Martha hummed happily to herself as she got things ready for Ginney's morning enema. As was the case every morning, she had struggled with the strong temptation to wander the house naked. Even though it was becoming more and more difficult for her each day, somehow she always managed to exercise some serious self-control and make herself presentable for her stepdaughter. After all, she couldn't just parade around nude in front of Ginney ... at least, not yet.

These morning outfits always consisted of the smallest wisp of material possible; just a thin layer of fabric between her bare flesh and Ginney's wandering eyes. Today she had chosen her classy Victoria's Secret green satin chemise. The thin fabric clung tightly to every curve of Martha's luscious body, clearly outlining her ample tits and nipples, and was just barely long enough to cover her ass and pussy. If she bent over even slightly these wonderful charms were completely exposed. Martha had worn this out as a dress before and received many complements.

Martha was especially horny this morning in light of Ginney's exceptional performance and compliance during yesterday's breakthrough session. She recalled fondly that watching the tape of Ginney's exam last night had gotten her and Susan so hot that they had deliberately left Martha's bedroom door wide open while they licked and fisted each others asses, boldly reveling in their deviant anal pleasure while her stepdaughter slept only a few doors down the hall. Such an exciting and eventful first day had left both Martha and Susan incredibly anxious to continue on with the next phase of Ginney's training.

Martha smiled as she thought of the day's plans for her young stepdaughter. Little did Ginney know that yesterday's catheterization had been just the beginning. Martha and Susan, after working hard for quite some time, had finally put the finishing touches on the plans for an entire new, ambitious and extremely extensive regimen that would take Ginney's training to new heights in the coming weeks. This would include the introduction of a wide range of exciting and innovative new treatments to supplement and greatly expand Ginney's current routine, making it even more exhaustive and elaborate than it already was. Starting with this week, Ginney's delicate female organs were about to face an onslaught of poking, prodding, examining, and stretching that was well above and beyond anything she had experienced thus far...

Ginney woke to the familiar stinging sensation of her stepmother slapping her ass. The slaps were hard enough to sting just a bit, but not hard enough to be mistaken for one of Martha's painful spankings. Martha had been waking her up this way each morning for about as long as Ginney could remember.

Ginney knew the next step would be for her to assume the position for her morning enema. Every single day of Ginney's life since she was barely a teenager had started out with an enema. Her stepmother had made it an essential part of Ginney's morning routine and had made sure not to miss even a single day of this important ritual ever since the enemas started years ago. Martha stressed that taking an enema was the most important thing to do in the morning, even more important than showering or brushing your teeth, and so it was always administered before Ginney did anything else.

Ginney moaned softly to let Martha know she was awake. The slaps stopped abruptly.

"Good morning. Are you ready for your enema, dear?" Martha asked pleasantly.

"Yes, mother," replied Ginney.

"All right. Stick out your bottom so we can begin."

Ginney raised her delectable buttocks as high in the air as she could, bending her knees while keeping her face pressed down on the pillow. Ginney then reached up with both hands and spread her asscheeks wide, exposing her pretty anus to her stepmother. Martha sighed as she took in the hot sight of her stepdaughter's sexy brown hole winking at her. Seeing this first thing in the morning always made her day.

Ginney gasped as she felt her stepmother rub a generous amount of lubricant onto her anus. She was then rewarded with the erotic sensation of first one, then two, then three fingers being jammed in her rear as her stepmother expertly loosened up her asshole. Ginney moaned as Martha began thrusting her fingers in and out of her ass.

"We're dealing with a fairly big nozzle this morning dear, so it's important to get you nice and loose," explained Martha.

Martha stopped the thrusting action of her fingers after a few moments and removed then from her stepdaughter's ass, leaving Ginney feeling terribly empty. Martha then lifted the large enema nozzle and pointed it directly at Ginney's glistening rosebud.

"Here it comes, dear. I hope you're ready," Martha said as she inserted the nozzle in Ginney's rear. This required some pushing and a bit of encouragement, but eventually Ginney's hole expanded to permit the large invader's entry.

The nozzle felt huge to Ginney as it made it's way up her hot ass. Martha had decided to use a 7 inch long, 1 1/2 inch wide stainless steel nozzle this morning. It felt absolutely wonderful as it inched it's way past Ginney's sensitive anal ring, causing her to moan and pant with pleasure. She was very disappointed that Martha stopped the insertion once her ass had swallowed the nozzle completely. Aching to feel the huge steel rod invade her ass further, Ginney tried to reach back and push it in deeper herself, but Martha stopped her. "Now, now, Ginney. Leave our friend right where he is," Martha scolded, trying desperately to hide the fact that she was positively delighted by her stepdaughter's display of wanton desire. The fact that her desire was caused by this early-morning invasion of her rear end was a testament to what a special girl Ginney had become as her training progressed.

As much as she wanted to, Martha couldn't allow Ginney to insert the nozzle past the 7 inch mark because these morning enemas were intended to stretch Ginney's lower bowels. Enemas given later in the day focused on the more exciting upper regions.

Martha opened the tap on the enema bag and the warm water began flowing into Ginney's rear. As it did, Martha made sure to stroke Ginney's asscheeks as always and pay a good amount of attention to her clit, but not enough to cause an orgasm.

When the small enema bag was empty, Martha sent Ginney off to the bathroom. A mere two quarts of water were used for Ginney's morning enemas because they weren't meant to test her limits; their main purpose was to stretch, clean, and prepare her lovely rear end for the rest of the day's activities.

When Ginney returned from the bathroom she was surprised to see Martha still in her bedroom, waiting impatiently for her.

"Is your rear nice and clean now, Ginney?" asked Martha.

"Yes, mother," Ginney replied.

"Did you check it carefully the way I showed you?"

"Yes, mother."

Martha required Ginney to carefully inspect her ass after her morning enema each day to make sure it was perfectly clean inside. This meant Ginney had to stand on the bathroom counter, bend over in front of the mirror, hold her asshole open as wide as she could with both hands, and inspect her rectum by peering between her legs at its reflection in the mirror. If any traces of feces still remained inside the sexy passageway, she was required to tell Martha that another enema would be necessary that morning. Ginney knew better than to lie to Martha about this as she would often double check Ginney's ass herself or, worse yet, burst into the bathroom unexpectedly to make sure Ginney was examining her rear properly. The few times she had tried to get away with not doing this in the past had resulted in brutal spankings by her stepmother. Ginney knew better than to disobey Martha's orders anymore, no matter how bizarre they sometimes seemed. Besides, she didn't really mind doing the inspection anymore. Much to her surprise, the view of her lewdly exposed rectum in the mirror had grown to be quite pleasant and familiar to her, as Ginney now knew every hot nook and cranny of her sexy rear end very intimately.

"Ginney, I'd like you to bend over the bed now. I have a suppository for you," Martha announced, holding up a large, semi-clear cylinder. This was a new type of suppository that had not been used in any of Ginney's prior treatments. Its purpose was not to cleanse Ginney's insides like the soap sticks used thus far, but instead to lubricate her entire bowel. Once inserted, the long solid tube would dissolve into a rather viscous lubricant with a consistency slightly thicker than semen. Martha thought it was important for her stepdaughter to become familiar with the wonderful feeling of having her ass filled to the brim with this cum-like substance; it would serve her well in the future.

Seeing Ginney take Nurse Alcott's entire hand up her ass yesterday had inspired Martha to select a bigger suppository this morning than she ever had before; she was determined to take advantage of this exciting and unexpected turn of events. Martha had picked one out that was 5 inches long, which was actually shorter than usual, but was a full 2 inches wide. This was a whole 1/2 inch wider than anything that had ever been stuck in Ginney's bottom prior to yesterday's breakthrough with the nurse. And it certainly was much larger than any device that had been inserted without the use of an anesthetic. Such a large size would be very beneficial to Ginney, since it would stretch her insides wonderfully while it was still solid, and fill her ass with lubricant to the point of overflowing once it had melted.

Ginney's eyes grew wide when she saw the size of the suppository. "Another one?" she complained, "but I just had a soap stick yesterday. Besides, that thing is huge. It's way too big."

"Nonsense," Martha replied with a stern look. "Now we both know what you were able to do with the nurse's hand yesterday, don't we?"

Ginney blushed fiercely.

"Answer me young lady!"

Ginney replied softly in a little girl voice. "YYYesss."

"That wasn't very convincing, dear. Now tell me what happened yesterday."

"I...uh...I...I...Nurse Alcott...stuck her...hand in my ass," Ginney stammered, embarrassed almost to the point of tears.

"I can't hear you!" Martha bellowed harshly. She was loving every minute of this interrogation.

"I took Nurse Alcott's entire hand up my ass!" Ginney blurted out, surprising herself.

"Yes, you certainly did, my dear. Not to mention a good portion of her arm. Why, she was in almost up to her elbow!" Martha said, beaming with pride over her stepdaughter's achievement. "So I'm sure you'll be able to handle this harmless little guy. Honestly, something of this size really shouldn't be a problem for a big girl like you, Ginney. I could see you possibly complaining about this a few years ago, but my God, Ginney, you're practically eighteen. Please act your age, dear."

"All right, I'm sorry Mom," Ginney replied, now feeling guilty for making her stepmother think she couldn't handle the responsibility of the large suppository.

"You know, you really should know what you're complaining about before you open your mouth," Martha scolded. "This is the minimum size necessary in order for the suppository to work. There's nothing I can do about that. Besides, I think you'll like this much better than your usual soap sticks. This one won't burn or sting. In fact, it should actually feel quite soothing as it dissolves in your bottom. Now bend over so I can stick this in you. We don't want you to be late for school."

Ginney obediently bent over at the waist, rested her head on the bed, and pointed her perfect ass directly at her stepmother.

"Ok, now open up and say, 'ahhhh'," Martha cooed.

Ginney giggled at Martha's joke as she relaxed her sphincter and tugged hard on her asscheeks, causing her anus to open wide and expose her lovely rectum to her stepmother's hungry gaze.

"You're going to have to open up wider than that, dear," Martha said with a smile. "Here, let me help you."

Martha plunged two fingers of each hand into her stepdaughter's open asshole, causing Ginney to whimper a bit at this sudden invasion. Martha loved the feeling of the soft, moist flesh of Ginney's rectal cavity on her bare fingers - unlike Nurse Alcott, Martha usually did not wear rubber gloves when manipulating her stepdaughter's anus.

Martha pulled outward as far as she could with both hands until Ginney's asshole was positively gaping. She held this position for a bit as Ginney groaned from the painful stretching of her tortured hole.

Martha then picked up the suppository to begin the task of inserting it, which she knew would be somewhat of a challenge. Not only was the suppository huge, but in it's current undissolved form, it was also rather sticky. In fact, it was so sticky that Martha couldn't slide her hand up or down its length no matter how hard she tried. Obviously, the use of some lubricant was required. However, for today's insertion Martha had decided to apply only a minimal amount of it to the suppository - just a very thin coating on the end that would go in first - the rest of it would remain completely unlubricated. Martha really wanted Ginney to feel the insertion of this extra large device.

Martha poked the lubricated end of the large rod at Ginney's anus, still using her free hand to hold open Ginney's tender hole. She tried very hard to work it into Ginney's ass, twisting it this way and that, but with no success.

"Come on, Ginney. This is no bigger than the nurse's hand was," Martha said.

Ginney concentrated on opening her ass even wider and after a moment, she felt the huge rod finally penetrate her rear.

"Ooooh!" Ginney moaned as the lubricated portion slid in rather easily. Next would be the difficult part: the remaining four inches that were unlubricated. Martha tried to continue the insertion, but the sticky rod wouldn't budge.

"Ginney," Martha said, "you're going to have to push out for me like you did yesterday when Nurse Alcott shoved her whole hand up your bottom."

Her mother had noticed that? Ginney was always impressed with how closely Martha observed her exams. Ginney knew it was because she loved her so much.

Ginney had no problem complying with Martha's demands as the extra wide suppository was creating wonderful sensations in her rear similar to those caused by the nurse's hand the day before. She desperately wanted to get the entire thing buried deep in her ass.

Ginney took a deep breath and then pushed out with all her might. Martha pushed on the rod at the same time and it finally slid forward a bit.

Ginney was totally unprepared for the feeling this would cause in her bottom. The sticky rod only moved forward about a 1/2 inch, but as it did it scraped abrasively against the ring of her asshole.

"Owwww!" Ginney cried in pain. Her sensitive hole felt like it was on fire. Nothing that had ever been done to her anus had felt quite like this.

In spite of this Ginney still felt a strong desire to engulf the whole rod deep in her behind. Fighting back tears, she pushed out again and the rod slid in further, causing her to cry out once again.

As the rod inched its way slowly up her stepdaughter's bottom, Martha reflected on the progress Ginney had made in the two years since her father had died. She had truly made great strides since then. Only a short time ago such an insertion would have been impossible. Now, despite the difficulty of the procedure, Ginney hadn't complained once. Martha knew she had picked the perfect time to begin the more advanced portion of Ginney's training. This training would soon enable Ginney's ass to accept objects as large as today's suppository with ease, and eventually, much larger devices.

Ginney was pushing out with all her might at regular intervals now, trying desperately to get the rod to advance further with each successive effort. As the rod continued its journey up Ginney's ass, the pain in her anus began bothering her less and less. In fact, it seemed to actually intensify the strong erotic sensations the suppository was creating in her rear. These sensations were enhanced even further when her stepmother began expertly rubbing Ginney's clit with her free hand. Only a few minutes of this lewd treatment were enough to fully awaken Ginney's hot natural desires as every nerve ending in her sensitive ass came alive. Her cries during each forward thrust were no longer cries of pain, but of pure lust caused by the urgent need she felt to jam the huge rod as deep in her hungry ass as she could.

"Oooohhhh!" Ginney moaned. "Keep ... pushing ... Mom ..... mmmmm .... further ... mmmuch further .... stick it wwwaay iinn me ... more .... feels ... so ... goood .... oohhhhh ... deeper ... please!"

Ginney was panting and moaning like a bitch in heat. Her lust had reached a fever pitch. She pleaded for more each time her stepmother slammed the rod into her hot ass with screams loud enough to wake the neighbors.

"Mmmmm .... ohhhh ... mmy GAWWD ... YES ... OOOHHH ... NEED ... MORE ... HARDER ... PLEASE ... SLAM IT IN HARDER, MOM!"

Martha gave the suppository one final hard thrust, impaling her stepdaughter as the rod slid all the way in to the hilt. Just as her ass swallowed the last of the rod, Ginney finally gave into her hot anal lust, erupting in orgasm with a primal scream.

Martha watched with approval as Ginney's entire body shook violently from her climax. She was absolutely thrilled with Ginney's reaction to the rough, abrasive insertion of the enormous rod in her rear end.

"Now that wasn't so bad, was it dear?" Martha asked with a sly grin on her face.

Ginney just smiled at her, her face flushed from post-orgasmic glow.

"Ginney, you've done a wonderful job this morning. I'm very proud of you. Come give your mother a kiss."

As Ginney hugged Martha and gave her a kiss, Martha caressed Ginney's cheek tenderly, her hand leaving a glistening trace of Ginney's rectal juices in its wake.

"Now Ginney, whatever you do, DO NOT REMOVE THE SUPPOSITORY FOR ANY REASON," Martha commanded. "It must stay in your little behind until later. You'll understand why eventually."

"Yes, mother," Ginney replied as she had been trained to, wondering what her stepmother meant.

As Ginney walked around school all day in her uniform, she was constantly aware of the lubricant suppository and the effect it was having on her rear end. For the first part of the morning her ass felt extremely full and stretched. This was quite pleasant in the beginning but after a while it became rather uncomfortable. In addition to this painful stretching, Ginney felt a very strong urge to move her bowels due to her body's natural response to the large anal invader.

Martha knew exactly what Ginney was going through this morning and thinking about it was making her very horny. However, she also knew that with enough training, Ginney would no longer have this type of reaction as her ass became accustomed to having very large objects jammed inside it on a regular basis.

The pain in her rear and the strong urge to move her bowels made this morning's treatment the toughest test of Ginney's endurance thus far. It didn't help that the sensitive flesh of her tortured rear had already gone through so much the day before and now only hours later the elastic properties of this lovely organ were being challenged once again. Her body was begging for relief from the constant stretching; Ginney wanted desperately to just remove the suppository and end this ordeal. However, fear can be a powerful motivator - she knew that her domineering stepmother would never forgive her if she let the suppository so much as poke even the tiniest bit out of her puckered asshole. The inevitable punishment she would receive would be far worse than any pain she was experiencing now, so she forced herself to deal with it.

As the suppository dissolved and got smaller, the pain in her bottom faded and was replaced by pleasant, soothing feelings caused by the lubricant. Ginney couldn't believe how good the lubricant felt on the sore, sensitive flesh of her internal organs after they had been stretched so brutally by the large rod. A wonderful sense of relief and well-being overwhelmed her as the soothing lubricant slowly began to fill her sore bottom, delighting her senses. At this point, Ginney scolded herself for even thinking about removing the suppository earlier. She realized that even though it didn't always seem so, her stepmother knew what was best for her. After all, Martha was only trying to make sure she stayed healthy.

Eventually, the suppository melted to the point where her ass was filled to capacity with lubricant goo. So much so, that some of it leaked out of her anus and began to collect in the seat of Ginney's frilly white panties. This turned out to be a godsend as it created the most delightful squishy sensation when she walked. It was even better when she sat down. As Ginney sat through class after class, she couldn't resist squirming around in her seat to make the goo trapped in her panties deliciously stimulate her delicate anus. Eventually, Ginney became so entirely focused on her hot rear end and the wonderful sensations emanating from it, that she was completely oblivious to the lectures given in class or even what class she was in for that matter.

During her last class before lunch, Ginney was surprised to receive a note from Nurse Alcott indicating that she was to report to her office today at noon sharp. Ginney thought this was strange. After all, she had just had her usual weekly exam yesterday. Also, she had never been ordered to come down during lunch before. Ginney couldn't imagine why the nurse would need to perform any type of additional procedure on her female organs today; they had already received a great deal of medical attention this week. Perhaps the nurse just needed to tell her something. On the other hand, she could never be quite sure these days - she was constantly amazed at the incredibly wide variety of unusual medical procedures her stepmother and the nurse were able to cook up.

As soon as class ended, Ginney hurried over to the nurse's office. Ginney entered the room and found Nurse Alcott waiting impatiently for her arrival.

"You're late again, Ginney," she said sharply.

Ginney noticed the clock read 12:05.

"I'm sorry," she replied, "but I don't understand. I just had my weekly exam yesterday."

"That's no excuse for being late, young lady! Now come along, we must get started."

Ginney followed the nurse back into the examining room. As she entered the room, she was shocked to see her stepmother waiting for her inside.

"Mom, what are you doing here?" Ginney asked quizzically.

"Is that how you greet your mother?" Martha snapped.

"Oh, no. I'm sorry."

Ginney hugged and kissed Martha on the cheek.

"That's better," Martha said. "Now before we get to why I'm here, let's address your tardiness. Ginney, what time did the nurse tell you to get here?"

"12 o'clock," Ginney replied.

"12 o'clock what?"

"Sharp."

"Exactly. Sharp means 12 o'clock. Not 12:01 and certainly not 12:05, young lady! Now why weren't you here on time?"

"Uh...I...d.d.d.don't know," Ginney stammered.

Martha knew why, however. In fact she knew exactly why: Nurse Alcott had purposely set the clock in her office several minutes fast to make sure that Ginney would be "late" today.

"Obviously, there is no good reason," Martha replied. "I suspected this might happen today. Nurse Alcott tells me that you're late quite frequently for your appointments in her office. Well, you won't be getting away with that anymore, young lady. You know very well that these treatments are extremely important and are NOT to be taken lightly. I'm afraid you leave me no choice but to show Nurse Alcott how to punish you properly. That way she'll be able to spank your nasty little behind herself whenever she feels you've been naughty."

Ginney was absolutely shocked by her stepmother's words. It was already embarrassing enough being 17 years old and still getting spanked like a little girl by her stepmother on a regular basis, but now her school nurse was about to witness it. She was positively mortified by the idea of getting spanked in front of Nurse Alcott. No one besides Ginney and her stepmother had ever known about her frequent spankings. Up until now it had been one of their dirty little secrets. Ginney had hoped and prayed no one would ever find out, but now Nurse Alcott of all people was about to witness it first hand. And to make matters worse, Ginney realized that in addition to the numerous spankings her stepmother gave her, she would also be receiving spankings from the nurse in the future. It was almost too much for Ginney to handle all at once.

Martha sat down in a chair and beckoned Ginney to come over for her spanking. The look of shock on Ginney's face was priceless; she had turned bright crimson with embarrassment.

"Nooo! Oh please no mom not here!" she Ginney pleaded as she began to cry.

"Ginney get over here at once!" Martha barked, "Now young lady!"

Ginney's whole body visibly trembled as she walked gingerly over to her stepmother.

As she approached Martha, Ginney couldn't help but notice her stepmother was dressed much more businesslike than usual. She had on a blazer over an extremely low-cut, cleavage- revealing top along with a very short slitted skirt. Her hair was up in a bun. Ginney thought her stepmother looked both sophisticated and pretty at the same time in this outfit.

The walk over to her stepmother seemed like it took forever to Ginney. When she finally reached Martha's side, Ginney reluctantly assumed the all-too familiar position across her stepmother's knees and awaited her punishment. Martha promptly flipped up her skirt revealing her panty- covered backside. Martha was quite pleased to discover a large, wet circle in the center of Ginney's panties caused by the lubricant that had leaked out of her bottom that morning, as well as an ample damp spot in the crotch area that was obviously due to Ginney's own "natural" causes.

Martha pulled Ginney's panties down slowly to her knees and was treated to the sight of the lubricant still oozing slowly out of Ginney's perfect posterior. Martha turned Ginney's panties inside-out to inspect the blob of goo that had collected in the seat of them.

"Well, nurse," she said with a grin, "it looks like the lubricant suppository is doing its job. Someone's made quite a mess in their panties..."

The nurse leaned over to have a closer and look and then agreed wholeheartedly with Martha.

"Nurse, would you please get the paddle out of my bag?" Martha asked.

Nurse Alcott rummaged through the large bag of toys Martha had brought with her and then pulled out a large paddle with the word "Assphalt" printed on the handle in big letters. This was no ordinary paddle. Martha had taken great pleasure in covering both sides with the coarsest sandpaper she could find, creating a delightfully rough surface to rub and strike her stepdaughter's asscheeks with. This was one of Martha's favorite devices for punishing Ginney.

Martha took care to apply her usual grip to the wriggling schoolgirl in her lap before beginning today's spanking. This meant sticking one hand up Ginney's skirt and lovingly cupping her pussy in order to stabilize her, making sure to rest her middle finger directly on her stepdaughter's pulsating clit.

With this important step out of the way, Martha was ready to begin Ginney's spanking.

"Now the first thing you do is stroke her asscheeks with the paddle," Martha lectured Nurse Alcott. "Most people think you just start whacking away, but that is a big mistake. Thorough rubbing of her rear is a very important part of the punishment. Do one cheek at a time, slowly at first, then pick up the pace."

Ginney groaned a bit as the rough material of the paddle mildly irritated the delicate skin of her rear. As Martha picked up the pace, the rubbing became increasingly painful. Martha continued the abrasive massage, applying more and more pressure with the increasing pace of each stroke. Soon Ginney's left asscheek felt like it was on fire causing her to whimper and beg for relief. Martha paid no attention to her stepdaughter's pleas; she was determined not to stop until she was good and ready. Martha continued for as long as she could, until she realized that if she went any further she would actually begin to cut into the soft flesh of Ginney's ass with the paddle.

"There, see you want to rub until the cheek turns a nice shade of pink," Martha said to the nurse as she lifted the paddle to reveal Ginney's rosy left asscheek. Tears ran down Ginney's face as Nurse Alcott carefully inspected her quivering buttocks.

"All right. Now the actual spanking can begin," Martha announced happily. With that, Martha quickly brought the paddle down hard on Ginney's left cheek, making a loud "thwack!" as it slammed into her sore flesh.

"Owwwww!" Ginney cried out from the sharp pain.

"Now don't worry about hitting her too hard," Martha continued as she whacked away at Ginney's left cheek. "Her cheeks should jiggle quite vigorously if you're doing it right."

Ginney was in serious pain now as her stepmother absolutely pummeled her rear. Tears flowed down her cheeks as she began to cry again. This didn't phase Martha one bit. She showed no mercy whatsoever as she continued drilling the paddle into Ginney's ass as hard as she could.

Finally, after she was satisfied that Ginney had been in serious pain long enough, Martha's finger began working its magic on Ginney's clit. Martha always made sure these spankings were an erotic experience for her stepdaughter. This was a very important part of Ginney's training. In order for her stepdaughter to become a proper young woman, Martha felt it was essential for her to find great sexual pleasure in being spanked. And she was more than willing to provide Ginney with the training that would make her lovely rear end - both inside and out - become one large, extremely sensitive erogenous zone. Martha knew that this was true for all women; it just took a bit of conditioning to bring it out.

Ginney was thrilled that her stepmother had finally started rubbing her clit. These wonderful caresses slowly began to transform Ginney as her insatiable teenage lust kicked in, causing her nipples to harden and her pussy to cream. Soon the awful pain she had endured for what seemed like an eternity melted into a wonderful heat that started in her pussy and radiated throughout her behind. At this point Ginney started to thoroughly enjoy her spanking. She began to eagerly anticipate each blow with excitement rather than dread, raising her buttocks up to meet the paddle each time it came down, and then thrusting her pussy down hard onto her stepmother's hand. Ginney moaned wantonly as she continued to thrust her hips and buck her rear in rhythm with the paddle. She writhed like a sex-crazed deviant in Martha's lap as the paddle continued to slam hard into her ass with a sharp clap of jiggling flesh

The instant Martha sensed Ginney was close to orgasm, she stopped the spanking abruptly.

"You stop once the cheek has turned a deep shape of red," Martha said to Nurse Alcott.

The nurse examined Ginney's left asscheek closely, noting with pleasure that it had turned beet red from the hard spanking. Ginney's other cheek looked ghostly white in comparison.

"I see," she said.

"Would you like to try it now?" Martha asked.

"I most certainly would," replied Nurse Alcott with a smile.

"Ginney, the nurse will finish your spanking now," Martha said.

That was perfectly OK with Ginney at this point. Her earlier embarrassment at being spanked in front of the nurse was a distant memory. She had been aroused to the very edge of sanity and then not allowed to cum. Ginney couldn't wait for her spanking to continue. She didn't care who gave it to her anymore. She just needed it now!

Ginney got up and eagerly waddled over to where Nurse Alcott was sitting as quickly as she could, the soiled panties at her knees making it difficult to walk.

Nurse Alcott enjoyed the feeling of the nubile young girl as Ginney positioned herself in her lap. She was very happy to discover that Ginney's pussy was sopping wet as her left hand explored underneath Ginney's sexy plaid skirt. Nurse Alcott cupped the wet cunt with her left hand like Martha had taught her, resting her middle finger on Ginney's engorged clit.

Then she lifted Ginney's skirt and began rubbing her untouched right asscheek lightly with the rough surface of the Assphalt paddle. This felt OK but Ginney really wished she would just get going and start hitting her hard with it soon.

Martha sensed this and said, "Nurse, maybe you should go a bit quicker on this round. After all, there's no need to prolong the poor girl's agony by dragging out the punishment." Martha winked at Nurse Alcott before addressing her stepdaughter. "Ginney, would you like the nurse to rub your bottom harder and faster with the paddle?"

Ginney nodded her head yes vigorously. Nurse Alcott and Martha exchanged a knowing smile; their young patient was continuing to impress them.

Nurse Alcott needed no further encouragement. She immediately began rubbing Ginney's ass with the paddle as hard as she could without cutting the poor girl. This felt heavenly to Ginney as the warmth in her left asscheek began to spread across her entire rear. She moaned with pleasure as she ground her pussy into the nurse's hand, but Nurse Alcott wasn't ready to let Ginney cum just yet so she moved her finger off of Ginney's clit, frustrating the young girl.

It didn't take long for the vigorous rubbing to turn Ginney's right asscheek a rosy pink.

"Well that looks good, Susan," Martha remarked. "It may be time to start the spanking. Ginney, would you like the nurse to start spanking your rear end hard with the paddle?"

"Plleassee!" Ginney begged with urgency.

Nurse Alcott's face lit up when she heard this. She wasted no time and immediately starting giving her sexy young patient exactly what she so desperately needed. She tore into Ginney's hide with the rough surface of the paddle, pounding as hard as she could. At this point she thankfully placed her finger back on Ginney's clit, sending the young girl over the edge.

"Owhhhh!" Ginney screamed as each whack of the paddle caused her luscious cheeks to clap and jiggle provocatively. "Nurse! Oh, Nurse!... Oooooooo...Harder!...Plleeassse Haaarderrr!...mmmmm...so GOOD... Oooohhh!...Owwww!"

Martha took a position directly behind her stepdaughter's upturned rear to get the best view of this incredibly hot spanking. She hiked her skirt up past her waist as she openly masturbated to the erotic scene before her. She was so pleased with Ginney as she watched her bucking her hips wantonly in the nurse's lap while the tender skin of her ass was abused by the paddle.

Ginney felt like an animal as she reveled in this savage treatment from her school nurse. Her pleas for more had now dissolved into pure primal screams of lust. These continued until the heat in her ass finally caused her to cum violently, shrieking at an even higher pitch as spasms wracked her entire body.

Nurse Alcott was extremely grateful that she had the presence of mind to have her examination room soundproofed at the beginning of the school year. Without the soundproofing, she was sure that Ginney would have been heard throughout the entire school and probably even out in the parking lot; she had never heard anyone scream that loud before in all her years of nursing.

As Ginney lay across her knees, her nubile body still twitching occasionally, Nurse Alcott brought her hand up to her face and lapped up every last drop of Ginney's sweet teenage pussy juice, looking Martha directly in the eyes as she did. This was enough to send Martha over the edge. She came as quietly as possible, hoping Ginney wouldn't look up suddenly and see her squatting there with three fingers jammed in her pussy.

Once Martha had regained her composure she stood up and addressed her stepdaughter. "There. Now that should teach you not to show up late again, young lady," she said sternly, finding it hard to keep a straight face.

"Mmmmm...yes, mother," Ginney replied dreamily from Nurse Alcott's lap.

"Good. Now I'd like you to get up on the examining table and lay on your stomach."

Ginney did as she was told.

"After punishing Ginney, I always apply some lotion to her bottom in order to heal and soothe the flesh," Martha explained to Nurse Alcott.

Martha went over to her bag and retrieved a large tube filled with a special lotion she had lovingly mixed herself.

"Ginney," Martha said, "please lift up your bottom."

Ginney raised her rear up off the table a bit. This allowed Martha to hike Ginney's skirt back up over her waist where it belonged.

Ginney's ass was quite a sight to behold. Both cheeks were a very deep shade of red, almost purple. Ginney provided an incredibly sexy display as she lay on the table in her hot little schoolgirl uniform with her skirt hiked up and her freshly spanked ass prominently displayed above her knee-high white socks.

"Now you just squirt the lotion all over and then rub it in good," Martha said as she squirted a very liberal amount directly into the crack of Ginney's ass and a lot more all over both luscious red cheeks. Ginney then felt both her stepmother and the nurse's hands roaming all over her bottom as they massaged the lotion into her tortured cheeks. Her stepmother and the nurse also seemed to pay a special amount of attention to her cute, crinkled asshole and cleanly shaven pussy, which was more than fine with Ginney. Her stepmother was always telling her that these were two very important areas to keep moisturized and soft...for medical reasons, of course.

When the massage was finished, Martha and Nurse Alcott stood back and admired their handiwork. Now not only was Ginney's ass beet red, the lotion made it glisten enticingly as well. It was all both women could do to resist diving in and lapping at it hungrily with their tongues.

"Ok, you can sit up now Ginney," Martha said.

Ginney sat up and faced them as Martha continued, "All right, now that your punishment is out of the way, I can finally tell you why I'm here today.

"Now Ginney, we all know that you have a bladder infection. Hopefully yesterday's treatment will put an end to it. However, the nurse and I have discussed it, and we are concerned that since this was most likely contracted while using the dirty school toilets, there's a very good chance that you may have a bowel or rectal infection as well. As you can see your little bathroom escapades have created a serious potential health risk for you, not to mention a lot of extra work for Nurse Alcott and I. Now do you see what can happen? I hope you realize how irresponsible it was of you to use the school toilets after I clearly forbade you to do so, young lady. Maybe next time you need to move you bowels, you'll think twice and actually hold it in until you get home like I told you to! Frankly, I find it disgusting that you would even consider placing your bottom on those filthy toilet seats anyway. Nurse Alcott and I just inspected them this morning, and honestly, they're so dirty that I think it would actually be more sanitary for you to have a little accident in your panties on the way home rather than using those disgusting things."

"Anyway, just to be safe, the nurse feels it is necessary for us to use a new type of treatment on your bottom today. It's called a colonic irrigation. I'm here today so that the nurse can demonstrate the procedure in case I need to administer it to you on my own sometime. I'll let the nurse explain how it works."

"Ginney," Nurse Alcott began, "I'm going to be demonstrating a rather elaborate procedure to your mother today. So, for instructional purposes, I'm going to be the doctor and your mother will be assisting me as the nurse during your exam. That means you will refer to me as 'doctor' and your mother as 'nurse' for the duration of the procedure."

"Nurse, remove the patients' panties and then get scrubbed and dressed in appropriate attire for today's procedure."

"Yes, doctor," replied Martha. She then slowly slid Ginney's panties down from her knees until they were off, being careful not to lose any of the precious lubricant goo covering the seat of them. She placed them carefully on the counter and then headed off to the adjoining bathroom to prepare for today's procedure.

"Let me tell you about the procedure now, Ginney," said Nurse Alcott. "I'm sure you know by now that all kinds of various toxins build up inside your bottom everyday. That is one reason why it is so important to take enemas regularly. Now enemas are certainly a good way to flush out the toxins in your rear, but a colonic is much more thorough and effective. Having said that, its important for you to understand that while colonics are very beneficial, they should never be used in PLACE of enemas. Doing so would be a horrendous mistake. No matter how many other kinds of treatments are used to help supplement and expand upon the numerous health benefits of your enemas, taking frequent enemas is still an absolute necessity, especially for a growing young lady like yourself - they are an absolutely essential part of maintaining a healthy rear end. Now that you understand that, let me explain how a colonic works. Administering a colonic involves using a special machine which I'll show you now."

Nurse Alcott opened a cupboard and took out the extra large colonic machine she had special- ordered just for Ginney. It was much larger and constructed differently than any normal colonic machine you would find at a clinic. The huge tube that would be inserted in Ginney's rear was 12 inches long and 2 inches wide, and was made of thick glass instead of the usual rubber.

Nurse Alcott knew that it would be impossible for such a device to be inserted successfully in just about anyone's bottom, let alone a pretty little one like Ginney's. However, a few weeks ago Nurse Alcott had made a startling, delightful discovery after while examining x-rays she had taken of Ginney's bottom. It turned out that incredibly enough, Ginney's rectum was a full 12 inches long! The typical size is only about 5 inches for most people. This explained a lot, including the reason why Ginney had always had problems with constipation. Never in her entire professional career had Nurse Alcott ever heard of a documented case of someone with such a large rectum.

Susan and Martha realized that they were truly blessed with a special patient. The sky was the limit for Ginney's unique rear end as far as they were concerned. To the delight of the two anally- obsessed women, they realized that incredibly large objects could be inserted into Ginney's ass once it was properly trained and stretched. They also theorized that Ginney would eventually be able to take extremely high volume enemas, perhaps 5 or 6 quarts, maybe even more than that.

So Nurse Alcott had gone out and ordered some special devices just for her exceptional young patient, including the extra large colonic machine. She knew from the careful measurements she had taken of Ginney's bottom that the tube was exactly the right length to just reach the first turn in Ginney's lower intestine when inserted fully. This would allow for the torrent of water to be fired directly at Ginney's sensitive intestinal wall while the width of the tube would test Ginney's ability to keep her asshole distended at a full 2 inches for the rather long duration of the procedure.

Ginney looked scared when she saw the size of the tube.

"Relax Ginney," Nurse Alcott advised. "Remember, I was able to stick my entire hand way up inside your bottom yesterday. This tube is much smaller than my hand."

Ginney still looked a bit concerned.

"Well I guess now you understand why your mother gave you that lubricant suppository this morning. Anyhow, here's how the procedure works. As you can see, the machine consists of a long glass tube, which has two smaller rubber tubes attached to one end. The glass one will be inserted in your bottom. You will notice that the glass tube has this doughnut-shaped, inflatable bulb on the end. This will be inflated so that the tube cannot possibly come out of your bottom until the end of the procedure. As for the rubber tubes, one of them will be connected to the faucet. The other will sit in this large plastic basin. When I open the tap on the tube connected to the faucet, warm water will rush into your behind. When I open the tap on the other tube, the water and whatever else was inside your dirty bottom will flow out and collect in the basin. That's how the procedure works: water is pumped into your rear and then drained out, then pumped in and then drained out, over and over again with the amount of water increasing each time. And that's all there is to it, dear. I'm sure you won't mind it once you get used to it. And the benefits of this treatment are tremendous. For example, removing the toxins from your bottom by colonic irrigation is absolutely wonderful for you skin. It improves your complexion and makes your skin softer and smoother. And I'm not just talking about the skin on your face; these benefits extend to your entire body, even the delicate skin on your bottom. That's why this procedure is so popular among fashionable, sophisticated young ladies in Europe."

"It is?" Ginney asked quizzically.

"Oh, absolutely. In fact, Princess Diana herself goes in for colonics regularly."

Well, if it was good enough for Princess Di, Ginney figured it was good enough for her. She no longer felt scared of the procedure at all. In fact, the nurse had done such a good job of peaking her curiosity that she was anxious to begin.

Of course, what Ginney didn't realize was that the colonic she was about to receive from the exceptionally large machine was nothing like the ones Princess Di got. No legitimate colon therapist would dream of using a tube even half as big as the one on Nurse Alcott's special machine.

"Well, as soon as my nurse shows up we can begin," announced Nurse Alcott. This was Martha's cue to come back into the examination room.

"Ahh, there she is now," she said as Martha stepped out of the bathroom door at the end of the adjoining supply room.

As Martha walked towards them, Ginney was surprised to see that she had changed into one of Nurse Alcott's sexy after-hours nursing outfits. The outfit consisted of a matching white top and shorts. The top was an extremely tight halter made of Lycra that clung to Martha like a second skin. It covered about three quarters of Martha's breasts on each side but plunged to a deep V in the middle that extended to the bottom of both luscious tits. The stethoscope around Martha's neck was tucked into this V, pulling it down even further. The top stopped several inches above Martha's navel, exposing her perfect tan stomach and sexy bellyring. The top was adorned with red crosses centered over each of Martha's tits, which served to draw even more attention to the bulging mounds of taut flesh. The crosses were accentuated by Martha's hard nipples protruding at the center of each through the tight material. The matching shorts were made of the same material and were cut high on the sides, exposing just a bit of Martha's jiggling asscheeks. This also made the shorts dig into every nook and cranny of Martha's body, exposing her pussy lips and asscrack to wandering eyes. Ginney also noticed that Martha was wearing the usual starched white nurses hat and a pair of white 4 inch heels, and was it her imagination, or did she have a lot more makeup on now than she did before?

Of the many different outfits Ginney had seen Nurse Alcott wear outside of school, this was one of her favorites. She thought her stepmother looked incredibly beautiful in it.

"How do you like my outfit, dear?" Martha asked before spinning around once to give her stepdaughter a complete view.

"Wow mom, you look great!" Ginney gushed.

"Thank you, honey," Martha replied, flashing Ginney a big smile.

"Yes, it certainly looks as though you're well prepared for today's exam, nurse," Susan chimed in.

"Thank you, doctor."

"Let's begin, shall we?" said Nurse Alcott. "Ginney, get up on the other table on your back with your feet in the stirrups. And hike your skirt up as far as you can."

Ginney obediently did as she was told.

"Nurse, tuck the patient's skirt under her sweater so it won't get in the way and then position her properly," Nurse Alcott ordered.

Martha lifted up Ginney's sweater and tucked her skirt up underneath it, letting her fingers graze her stepdaughter's bra in the process. She then moved Ginney down to the usual position with her bottom sticking off the end of the table and her legs up at almost a 90 degree angle in the stirrups. Her most private parts were now lewdly exposed, just waiting to be probed and examined by her stepmother and school nurse.

Nurse Alcott took a moment to enjoy the incredibly erotic scene in front of her before beginning the exam. Ginney looked so hot lying there with her plaid pleated skirt hiked up and her legs suspended in the stirrups half-covered by her knee-high white socks. Her pussy lips were still moist and engorged with the arousal caused by her spanking. And below them, her flesh changed colors dramatically as her ass was a still a very deep shaped of red. Susan noted approvingly that the lubricant was still oozing out of her ass slowly and a little puddle of it was starting to form on the floor.

After a moment, Nurse Alcott decided to begin the exam. The first item of business would be to remove Ginney's suppository.

"Nurse, bring me an anal retractor," ordered Nurse Alcott.

"Here you are, doctor."

Susan felt a shiver of excitement as she took hold of the large stainless steel spreader. The purpose of this device was the same as that of a speculum, but it was much longer and the blades were much thinner. She liked to use a wide variety of instruments on Ginney's asshole to keep things interesting and to provide different types of stretching to the pliant opening.

Nurse Alcott began to insert the long device slowly into Ginney's well-lubricated backside. Once Ginney had taken all ten inches of it rather easily, Susan opened the device and locked it in place at a width of 2 inches. Ginney groaned in pain from the sudden stretching of her sensitive hole. The goo filling her rear now began to slide out more copiously through her wide open pooper.

"Nurse, fetch the light for me."

Martha handed Nurse Alcott an examination light. Susan aimed the beam directly up Ginney's rear, giving her and Martha an excellent view of the yellowish lubricant sloshing around Ginney's insides. They could see what was left of the suppository as well: being as thick as it originally was, it was still a good 1/2 inch around.

"Nurse," Susan said, "the suppository still hasn't completely dissolved in the patient's rectum. Take a look."

Martha leaned over and peered up into her stepdaughter's open rear end. "You're right, doctor"

The two women proceeded to chit chat about why it hadn't dissolved, whether or not there was enough lubricant in Ginney's bottom, if additional measures show be taken, etc. Susan kept the flashlight pointed directly up Ginney's ass as she and Martha scrutinized the state of their young patient's rear in excruciating detail. They continued this discussion for as long as possible as both women were very aware that Ginney was struggling with the painful stretching of her delicate asshole the entire time.

Ginney remained fairly quiet during this part of the exam, only grunting and groaning softly as she squirmed on the table - she was determined to behave for her mother and Nurse Alcott while she underwent this important procedure. But the intense stretching of her sensitive hole eventually took its toll on the poor girl. Just before she was about to cry out that she couldn't take it anymore, Nurse Alcott finally unlocked the retractor and removed it from her bottom, at last giving Ginney some relief.

Nurse Alcott announced that it was time to remove what was left of the suppository. She donned a pair of rubber gloves and asked Martha to lubricate her hand. Martha got out a tube of K-Y jelly and squirted a liberal amount all over Nurse Alcott's right hand and up her forearm. She then used both hands to spread the lubricant evenly from Susan's gloved hand all the way up to her elbow. The lubricant was necessary because Nurse Alcott was going to remove the suppository in a rather unconventional way - by sticking her whole hand up Ginney's hot ass. Upon discovering Ginney's ability to accept an entire hand deep in her bottom yesterday, Nurse Alcott had decided then and there that from now on she would remove any and all devices from Ginney's rear end in this way and ONLY in this way. She was absolutely thrilled that Ginney had achieved this important milestone ahead of schedule.

Nurse Alcott slid two fingers of her lubricated hand easily into Ginney's backdoor, causing the young schoolgirl to gasp slightly. She proceeded to work three, four, and then all five fingers into the distended hole. After a bit of encouragement from Martha ("Push out for the doctor, dear"), Susan's knuckles slid past Ginney's anal ring and she was in up to her wrist in one quick motion.

"Ooooo!" Ginney moaned from the sudden invasion.

Susan slowly began twisting her hand in Ginney's bottom, probing the inner reaches of her favorite patient. The lubricant filling her hot rear was soft and squishy on Nurse Alcott's hand; it felt as though someone had poured a container of molasses inside the young girl.

Ginney began moaning and writhing with pleasure as the nurse's hand felt even better in her ass than it had yesterday. There was an even greater feeling of fullness this time due to the huge amount of lubricant trapped in her rectum. The nurse was sloshing it all around with the motion of her hand, which felt absolutely heavenly as it oozed across her sensitive anal tissue.

Nurse Alcott located the suppository and grabbed the end of it. Ginney felt the nurse's hand start to move back out of her ass. "No!" she thought, "she can't be taking it out already!"

But just as Susan's knuckles reached Ginney's asshole, she thrusted her hand back in hard. Ginney squealed in delight at this wonderful invasion of her backside.

Susan began shuttling her hand in and out just as she had the day before, bringing it out to the knuckles each time before thrusting forward once again. The two quickly found a rhythm this time as Ginney took advantage of the valuable lesson she had learned the day before and pushed her asshole out with all her might each time the nurse's hand surged forward. Each stroke elicited a high-pitched scream of girlish pleasure from Ginney.

Both women were breathing heavily as the reaming continued - Susan from the exertion of the thrusting action and Ginney from the strenuous task of manipulating her asshole. Eventually, Nurse Alcott's hand reached the delicate entrance to Ginney's lower bowels. She stopped suddenly. The going had been very slow once she had reached this point yesterday. However, this time Susan had the suppository to work with. She brought her hand way back - almost all the way out of Ginney's ass - and then thrusted in extra hard, burying herself to her mid-forearm in one obscene plunge. Nurse Alcott was gratified to feel the end of the suppository poke through Ginney's rectal sphincter this time and into her sensitive lower bowels.

"OH....MY....GOD!" Ginney cried. The feeling that shot through her body as the suppository penetrated her lower bowel was pure bliss.

Unsure as to whether this was a cry of pain or pleasure, Nurse Alcott nonetheless continued her thrusts with vigor.

"Oooh....oooo....Oh, nurse....YYYesss.....deeper....deeeeper....further......I can take more....much more.....mmmmm....plleeassseee....deeeeper..." Ginney cried out.

Ginney's unintelligible screams of pleasure continued until finally her whole body convulsed as she had her third mind-bending orgasm of the day.

Nurse Alcott was very happy for Ginney. Based on what Martha had told her this morning, it looked as though she would have an orgasm each time one of these suppositories was inserted or removed from her bottom - Susan certainly hoped so. She mused that there would undoubtedly be many, many chances to test that theory in the coming weeks as lubricant suppositories would be used extensively throughout the rest of Ginney's training.

Ginney was disappointed when the nurse finally removed her hand from her hot rear - it just felt so EMPTY back there.

Susan handed Martha the suppository and said, "Nurse, bring me a towel." A thick coating of the gooey lubricant from Ginney's ass covered her arm almost all the way up to her elbow. Unfortunately, she needed to clean off the sexy fluid so she wouldn't soil her school nurse's uniform.

Susan quickly toweled herself off and then said to Martha, "Now that I have done my best to dissolve as much of the lubricant suppository in our patient's bottom as possible, we can perform the colonic irrigation."

Did you hear that, Ginney?" asked Martha. "Are you ready for your first colonic?"

"Yes."

"Yes, what?"

"Yes, I'm ready for my first colonic, mother."

"Doctor, I want to make sure the patient understands how this procedure works before we begin," Martha said to Susan. "Now Ginney, I want you to tell me what's about to happen to you."

"The nurse is going to stick the long tube in my bottom and squirt water up inside me."

"I'm the nurse and Ms. Alcott is the doctor today, young lady!" Martha corrected her. "And the water doesn't just squirt out, it shoots into you quite hard. I thought you understood how this procedure worked! Now, are you ready for the doctor to stick the long tube up your bottom and shoot water deep into your bowels, dear?"

"Yes, mother."

"All right. Then why don't you ask the nice doctor to do that for you so we can get started."

Ginney sighed in frustration. She knew her stepmother would make her sit there all day if she didn't do as she was told. She looked up at Nurse Alcott and said sweetly, "Doctor, would you please stick that big glass tube in my bottom and shoot water deep into my bowels?"

"I'd be delighted to, my dear," Susan replied. "But first I'm going to need you to open up very wide for me."

Ginney placed both hands at either side of her rear and pulled, opening her sexy asshole once again.

"You're going to have to open up wider than that, honey. Try sticking a few fingers in and pulling out."

Ginney stuck two fingers of each hand in her ass and pulled out with all her might. Her asshole responded and was soon gaping open obscenely wide.

"No, I'm afraid that just won't do," said Susan. "Nurse, why don't you assist the patient with her asshole."

Martha leaned over and placed two fingers of each hand at the top and bottom of her stepdaughter's asshole. She pulled hard at the elastic opening, her fingers at the top and bottom augmenting the pressure applied by Ginney's fingers at the sides.

Ginney groaned as her poor browneye was stretched in every possible direction.

"Ahh, that's better," said Nurse Alcott happily.

She then positioned the tube in front of the wide open hole and inserted the end slowly. The two older women watched with glee as Ginney's asshole was stretched by the enormous 2 inch wide tube as well as the fingers from four different hands. The lubricant in her rear did its job as the long tube began to slowly disappear between the schoolgirl's bright red bottom cheeks.

The tube felt ridiculously large to Ginney; and it really hurt. In fact, as it made its way up her spicy behind it felt like she was being RIPPED apart. As pain radiated throughout her bottom, Ginney couldn't help but let out a few moans and whimpers. She tried her best to limit these however - she was determined to take this obscene invasion of her rear end like a lady. After all, she was sure Princess Di never made a fuss during her colonics. Despite her determination, Ginney couldn't help shedding a few silent tears as the huge tube tore into her sensitive bottom.

At the last, the tube was in all the way and Ginney felt Nurse Alcott inflating the doughnut- shaped bulb near the base. This only served to intensify the painful stretching of her insides.

Nurse Alcott was both surprised and impressed with how well-behaved Ginney had been during the painful insertion of the enormous tube in her bottom. The progress she had made over the past several months was astounding. Susan and Martha exchanged a knowing smile as both women realized their sexy patient was really becoming a fine young woman.

"Nurse, bring me the examining light," Susan said to Martha, causing Ginney to wonder what was going on. Nurse Alcott detached the plastic cap and rubber tubes from the end of the large glass tube. She wasn't ready to begin Ginney's colonic just yet. First, she wanted to check the position of the glass tube in her patient's bottom.

Nurse Alcott pointed the small light up the tube. She was pleased to see the side of Ginney's intestinal wall at the other end; her measurements of Ginney's bottom had been perfect. She let Ginney's stepmother have a look up the tube and then reassembled the machine.

"All right Ginney, now before we begin I just want to let you know that this quite a lengthy procedure," Nurse Alcott said. "But don't worry, you've already been excused from your study hall next period."

A lengthy procedure? Ginney wondered how long she could possibly endure having the gigantic tube jammed in her ass. She feared that she was about to find out.

"Nurse, run the faucet to until the water reaches exactly 100 degrees," Susan ordered. "Then connect the rubber tube to it. And make sure the faucet is on as high as it will go."

Once Martha finished these tasks, it was time to begin the colonic. Susan let the water pressure build in the rubber tube a bit before unleashing it on Ginney's unsuspecting bottom.

"I hope your ready for the water, dear. Here it comes!"

Ginney couldn't have possibly prepared herself for what happened next.

The water shot out of the machine with incredible force, slamming directly into Ginney's intestinal wall. Ginney was stunned by the power of the machine - this was nothing like taking a simple enema. It felt like someone was spraying a fire hose up her rear.

The blast, though powerful, was a short one. Nurse Alcott closed the tap on the faucet tube after she had fired only about a pint of water into her patient's bottom. Quickly, she opened the tap on the drain tube and Ginney felt the water rush back out of her and into the basin. Nurse Alcott opened the tap on the faucet tube and another powerful blast rocked Ginney's insides. She continued this pattern, injecting a slightly larger amount of water each time and gradually forcing Ginney to retain it longer and longer before expelling it.

As her colonic continued, Ginney was surprised to discover that she was actually beginning to enjoy it. The action of the water produced intensely erotic sensations in her bottom as it drilled hard into her sensitive bowels. And she especially enjoyed the sensual massage she was receiving from her stepmother. Martha did this under the guise of massaging Ginney's belly, but her real purpose was to rub her stepdaughter's clit, which she did enthusiastically, expertly making it appear to be incidental contact. Soon Ginney was moaning and sighing with pleasure. She barely even noticed the pain from the huge glass tube anymore. She decided that she absolutely loved this new treatment.

The colonic continued for what seemed like an eternity to Ginney, with her stepmother and Nurse Alcott taking turns operating the machine while the other massaged her belly. Although she really enjoyed it at first, as the procedure wore on, it became increasingly difficult for Ginney to endure. After about a half hour, her anus really began to have a tough time maintaining the two inch opening required for the glass tube. The colonic still felt wonderful whenever the water was fired into her, but the time between filling and draining had become quite long. It was during these times that the painful stretching of her asshole was most apparent. Retaining the water had also become a bit of a chore as she was now being filled each time to the point where her stomach bulged out and she appeared to be a few month's pregnant.

To help herself make it through these tough times, Ginney imagined that she was Princess Di, receiving her colonic somewhere in Buckingham Palace from her own Royal Nurse. Ginney felt truly honored to be receiving the same treatment as such a classy lady. In fact, the more she thought about it, the more she realized that she was a very lucky girl: her stepmother and Nurse Alcott were treating her like a princess! She had never felt this sophisticated in her entire life! Ginney smiled slyly as she mused that Princess Di was also probably naughty at times and required a good spanking. A feeling of great pride overwhelmed her as she lay prone on the examining table, forced to take her colonic like a proper young lady.

At last, Nurse Alcott decided it was time to end the procedure. She wanted to fill Ginney up to her known limit of 2.75 quarts to close things out, but it was hard to tell exactly how much she was injecting with this machine. She decided it was better for Ginney to be too full than not full enough so she really let her have it. Ginney groaned as her insides were stretched to their limit. Ginney was forced to retain this final load for a full ten minutes. Martha rubbed her clit intensely the entire time, bringing Ginney agonizingly close to another orgasm. She stopped abruptly when Nurse Alcott opened the tap and let the water drain out of Ginney's bowels, leaving her stepdaughter aching for release.

Nurse Alcott made a note on Ginney's chart that her colonic had lasted almost exactly one hour. She planned on making each successive one a bit longer in the coming weeks as Ginney's training progressed and she got used to the procedure.

Once the last of the water had finally gurgled out of Ginney's bowels, Susan took hold of the glass tube and began to remove the machine from her patient's overworked rear end. She did this at an agonizingly slow pace, prolonging the stretching of Ginney's helpless anus for as long as possible. The water had rinsed away most of the lubricant, so as the tube passed through Ginney's sensitive anal ring it created an absolutely wonderful friction. Every nerve ending in Ginney's asshole sent shock waves of pleasure through her as the enormous tube passed roughly through her sensitive hole. Even the slightest movement of the tube produced moans of pleasure from Ginney.

At last the end of the tube slid out of Ginney's ass with a pronounced popping sound. Ginney was grateful to finally be able to rest her sore anus. It seemed as though it had been open more often today than it had been closed. In fact, now it seemed like it didn't WANT to close. Ginney could feel the cool air form the room rushing in through her partially open hole, tickling her insides.

Nurse Alcott noticed this as well and was quite pleased. She made a note on Ginney's chart that her asshole had remained open about 1/2 an inch after the tube was removed. This was another important stage of Ginney's development that they would be improving upon with further treatments and monitoring closely during future exams.

Ginney was certainly happy to get a break from the painful stretching of her asshole. However, now her bottom felt terribly empty, like something was missing; something big and important that BELONGED back there. Having been brought agonizingly close to orgasm, but then not allowed to climax had left her overcome with lust. Anal lust. So much so that she was unable to remain still on the table. Her whole body twitched with desire...she wanted more.

Martha and Nurse Alcott watched with amusement as Ginney struggled with her horny state. Of course that matter would be taken care of eventually. Being the excellent medical professionals they were, Susan and Martha weren't about to let their patient go unsatisfied. In Nurse Alcott's mind, that was equivalent to malpractice.

"Well Ginney, you handled your colonic quite well," Susan said. "In fact, I think you might even be able to give Princess Di a run for her money."

Ginney broke out into a huge smile. "Wow, really? Thank you, doctor!" she said, getting into the game now. She was absolutely thrilled by Nurse Alcott's complement. It was the nicest thing she had ever said to her.

"Now don't move Ginney," said Nurse Alcott. "We're not done yet."

"THANK GOD" thought Ginney.

"Nurse, bring me the proctoscope," ordered Susan.

Martha returned with another glass tube that was of the same exact dimensions as the one that had just been in Ginney's ass. It was another extra large instrument Nurse Alcott had obtained just for Ginney.

Ginney got excited as soon as she saw it.

"Doctor, are you going to stick that in my bottom?" she asked eagerly.

"Why yes I am dear," Nurse Alcott replied happily, unable to stop herself from smiling wickedly. "I'm going to stick this way up inside your little rear end. But hold your horses, young lady. I know you're very eager to get healthy my dear, which is wonderful, but you must learn to have some patience. In order to further your medical education, Ginney, first I'm going to explain to you how this ingenious device works.

"You know, you really should feel lucky that not only are you receiving an incredible amount of private medical attention, you are also acquiring a great deal of valuable medical knowledge along the way. I guarantee you that most girls your age aren't getting this type of education from their mothers. God knows, I wish my mother took the time to teach me these things when I was your age. I think you will find that this all ends up being even more useful than the formal education you are receiving at school. Especially if you want to follow in your mother's footsteps and major in nursing."

Ginney wasn't so sure about that, but she was so horny, she really didn't care at this point. All she could think about was getting something, anything, back up inside her tight, young ass.

"Ok, Doctor Alcott," Ginney replied breathily. "I guess it's just that I REALLY, REALLY want you to continue examining my bottom...I don't want to get sick."

"Well Ginney, I'm glad to see that you're finally taking this as seriously as your mother and I. After all, it's not like I go around sticking anything I can get my hands on up your bum, you know. This isn't a game, my dear." Martha and Nurse Alcott exchanged looks of amusement. Both women knew this couldn't have been further from the truth.

"Now," she continued, "this device is called a proctoscope. Doctor's use this to do detailed examinations of patient's behinds. As you can see there is a thin fluorescent light strip running down the length of the inside of the tube. Once the tube is inside you, the light will illuminate your entire bottom. This will allow me to examine your bottom thoroughly for signs of infection. So, are you ready begin, Ginney?"

"Yes, doctor. Please stick that big tube up my rear. I'd really like to know if I have an infection." Ginney threw that last part in about the infection just so her stepmother and the nurse wouldn't think she was taking this important medical procedure lightly. The truth was, her ass was practically begging for further attention.

"Very well then," Nurse Alcott said, noting Ginney's eagerness. "Nurse, lubricate the patient's asshole while I work on the proctoscope."

Ginney then felt the familiar sensation of her stepmother massaging lubricant into her anus.

Nurse Alcott meanwhile was spreading lubricant onto the "proctoscope", stroking it as if she was jerking off an enormous cock.

Nurse Alcott ordered Ginney to open up wide once again for the insertion. Ginney knew what to do this time. She stuck her fingers in her ass and pulled out with all her might. Right away, she felt her stepmother's long fingers join her own, aiding in the stretching of her asshole.

Nurse Alcott inserted the end of the proctoscope and switched on the light, giving her a beautiful view of the delights normally hidden inside Ginney's puckered anus. She could see the glistening tissue of Ginney's most private and intimate place expand to accept the large invader as she pushed it forward slowly, driving it deeper into the hot recesses of her patient's sexy bottom.

As the enormous tube made its slow journey into her sensitive rectum, Ginney couldn't help moaning sensually. It felt soooo good. She wanted it as far up her ass as possible. She really wished it was longer.

Regretfully, Ginney felt the end of the tube bump into her intestinal wall much too soon. All 12 inches of it were now buried in her ass.

Nurse Alcott took her sweet time enjoying the view afforded by the tube protruding from Ginney's stuffed bottom. She pretended to make notes on Ginney's chart as she peered through the tube lustfully, muttering things like "hmm, that's curious" along with various phony medical terms as the fake exam proceeded almost comically.

After quite a bit of this, Susan decided to give Martha a turn. "Nurse, why don't you have a look up you daughter's ass?" she said to Ginney's stepmother.

Martha gladly took a turn peering up into the tube sticking out obscenely from her stepdaughter's behind. The two women exchanged phony medical talk as Martha enjoyed the erotic view of her stepdaughter's most intimate organs.

After a few minutes, Nurse Alcott reached over and spread Ginney's pussy lips. She discovered that Ginney was sopping wet. In fact she was so wet that her pussy juice was dripping onto the floor, mixing with the puddle of lubricant goo that had oozed out of her ass earlier. Susan also noticed pleasantly that Ginney's peehole was still a bit swollen and distended from last night's manipulations. Above that, she noticed Ginney's clit, engorged and pulsating harder than she had ever seen it before.

"Nurse, this is quite remarkable," said Susan as she peered into Ginney's open pussy. "You can see the proctoscope through the patient's pussy. Have a look."

Martha leered directly into her stepdaughter's pussy and saw that Susan was right. She could clearly see the light from the proctoscope through the narrow wall separating her stepdaughter's pussy from her rectum.

"Why doctor, you're right. I can see it clearly," said Martha, trying to sound as clinical as possible.

"Nurse, take my position here," said Susan. "I want to try something."

Martha took over for Susan, keeping her stepdaughter's pussy lips spread.

As Martha bent over to get at her pussy, Ginney noticed that the stethoscope dangling between her stepmother's breasts swung forward, pushing the thin fabric of Martha's revealing, low-cut top a good six inches away from her sexy body. Ginney gasped as her stepmother's gorgeous tits came into full view, hanging out fully exposed, the turgid nipples sticking straight out at attention. Martha continued to keep Ginney's pussy open with both hands and acted as if nothing had happened. "How could she not notice?" thought Ginney.

Martha noticed all right. In fact she had purposely weighed down the end of the fake stethoscope so that this would happen. She had tested it in the mirror this morning. She new that any time she leaned over far enough her tits would be completely exposed to Ginney. "Nothing's too good for my daughter," she thought with a grin.

"Ok, Nurse. I want to see what happens when I move the proctoscope," said Susan. She reached between Martha's legs to get at Ginney's ass and began pumping the huge rod back and forth, causing Ginney to pant and moan uncontrollably. As she did this, her arm conveniently rubbed against Martha's wet crotch.

"Can you see the scope moving through the patient's pussy?"

"I certainly can, doctor," replied Martha.

"Good. That will serve us well," replied Susan cryptically. "Ginney, I'm going to have to move the proctoscope back and forth in your bottom. This is the most important part of the procedure because the thrusting action of the tube will dislodge any bacteria clinging to the walls of your bowels."

"Ok," replied Ginney. She didn't care what this procedure did. She just wanted Nurse Alcott to start fucking her ass with the big tube.

"Nurse, I'd like you to observe the proctoscope through the patient's cunt while I look up her ass. In order to do this, you're going to have to assume the Klinefelter Position," said Susan.

"Yes, doctor," replied Martha. She and Susan had come up with the phony name for the position after Ginney's exam last night.

Martha got up on the exam table and straddled her stepdaughter's stomach facing Nurse Alcott. She then laid down with her face just inches just inches away from Ginney's pussy. Ginney could feel her stepmother's hot breath on her clit.

Martha's gorgeous ass was now right in Ginney's face. Ginney didn't mind this at all; she thought it was very pretty. Little did she know that Martha was considering taking this position in the future wearing a short skirt and no panties.

Ginney stared straight at the large red cross in the middle of Martha's shorts as her stepmother's rear end covered her entire field of vision. Below that, Ginney was surprised to see that the white material of the shorts appeared to be quite wet in the crotch area.

"All set, doctor," said Martha as she reached down and spread her stepdaughter's pussy lips.

"Ok, here we go," said Susan as she began thrusting the tube back and forth. As the tube moved in and out through Ginney's rear, she could clearly see the delicate tissues of the young girl's bowels expanding and contracting in rhythm. Susan really loved this device.

Martha was also enjoying her view; she could clearly she the light from the tubing moving through Ginney's pussy. As she stared into her stepdaughter's open cunt, Martha used her free hand to rub Ginney's clit.

Ginney was once again on cloud nine as the tube and Martha's finger's both felt absolutely incredible. She cried for Nurse Alcott to go harder and faster in between her moans of pleasure. Again, she found herself wishing that the tube was longer.

Nurse Alcott fucked Ginney's ass hard with the tube until she thought Ginney was at the peak of her arousal. At this point, she stopped abruptly, causing Ginney to groan in frustration.

"Well, so far Ginney I'd have to say the results of this exam are inconclusive," said Nurse Alcott. "But an infection is a definite possibility. There certainly seems to be a lot of bacteria in there, which we hopefully were able to dislodge with the proctoscope. In order to be certain whether an infection exists or not, I need to examine much more of your bottom. This will involve the use of a much longer device called a sigmoidoscope. However, I have to warn you that if we proceed with the exam, there is the risk of the sigmoidoscope puncturing your intestinal wall, so I will only perform the rest of the exam with your permission. Bear in mind that it is extremely important that we identify any possible infection as early as possible."

This was music to Ginney's ears. She loved the proctoscope exam and now she was about to get something even longer stuck up her bottom! Much longer, according to Nurse Alcott. At this point, she didn't care that it might puncture her bowels. All she could think of in her horny state of mind was how wonderful it would be to have something else forced up her ass.

"Well Ginney, would you like to continue with the exam?"

"Oh yes, doctor. Please do," replied Ginney around her stepmother's ass.

Nurse Alcott and Martha were both delighted by Ginney's response. "Excellent," said Nurse Alcott. "You've definitely made the right choice, Ginney. I just need to go get sigmoidoscope and then we can begin. Nurse, you might as well remain in the Kleinfelter Position so you can massage the patient's bowel area during the procedure."

Nurse Alcott walked back to the supply room, purposely leaving the proctoscope in Ginney's ass.

Ginney was shocked when she saw Nurse Alcott return from the supply room carrying a 50-inch long rubber tube. This tube was a full 20-inches longer than the colon tube Ginney had grown accustomed to having up her ass during her enemas, and a lot wider. It was only about 1/2 inch wide at one end, but gradually expanded to a full 2 inches at the other end. Nurse Alcott had put this beauty together herself. The idea had come to her in a stroke of brilliance. She special- ordered the rubber tube and then simply placed an ordinary sigmoidoscope inside it. Based on her own painstaking measurements of Ginney's bottom, she had modeled the tube to fit her young patient's insides perfectly. The varying width of the tube coincided exactly with the varying width of Ginney's bowels, leaving only a tiny fraction of space for the tube's passage. This perfectly snug fit along with the ribbed surface of the tube (another special feature) would provide Ginney's bottom with maximum stimulation. Susan envied her lucky young patient.

Just to add a bit of excitement to the proceedings, Susan had decided to go with a very thick black rubber when she ordered the tubing. So thick that it would just barely be bendable enough to make it through the turns in Ginney's bowels. At least, Susan thought it might be...either way, they were about to find out.

"Don't look so surprised Ginney," said Susan when she saw the look on Ginney's face. "Your bowels are over 4 feet long and I need to examine every square inch of them. This is a normal procedure that's performed in hospitals every day. Now, I just need to lubricate this and we can begin."

"Are you done yet?" Ginney asked after a few minutes had passed.

"My, my. Someone's quite eager to begin, aren't they?" Nurse Alcott replied with a big smile and a wink as she rubbed lubricant onto the last section of the tube. The entire length of the black tube glistened menacingly in the harsh fluorescent light of the examining room. "Well I can't stress enough how glad I am to see that you're becoming as passionate about anal health as your mother and I are."

Martha and Nurse Alcott exchanged glances. Both women were ecstatic; Ginney was responding better to this treatment than either one of them could have dreamed.

"Well, you're in luck, dear. We're about to begin," said Nurse Alcott. "Now you're probably wondering how in the world I'm going to see way up into your bottom using this thing. Well, unlike a proctoscope, a sigmoidoscope has a tiny little TV camera inside it. As I slide the tube into you, a picture of your insides will be displayed on this nice big TV monitor."

Susan wheeled a large 35 inch TV over to the side of the examining table so Ginney could see what she was talking about.

"Wow, you can see it on the TV?" asked Ginney.

"That's right. Your bottom's gonna be on TV, Ginney!" answered Nurse Alcott. "Now obviously, you won't be able to see this TV during the exam, Ginney, but if you'd like I can put it up on the screen above you, too. If you know what's good for you, you should check it out. After all, you can never know your own bottom too well."

For the first time Ginney noticed the large, flat TV screen built into the ceiling above her.

"Nurse Alcott's right, Ginney," Martha chimed in. "Up until now, you've only been able to study a small part of your bottom in the mirror. But there's much, much more to explore back there. A lot of people never get this opportunity."

"Well Ginney, would you like to see the inside of your bottom?" asked Nurse Alcott.

"Ginney, what do you say to the nice doctor?" Martha interjected as if she were directing a young child to say thank you to someone.

Ginney didn't think this was really a choice for her to make. She suspected that if she said no, a punishment of some sort would be forthcoming. She also wanted to get the exam started as soon as possible, so she said exactly what she knew her stepmother wanted to hear. "Yes, doctor. Would you please turn on the big TV above me so I can see up inside my bottom during the exam?"

"That's a good girl," cooed Nurse Alcott. "Nurse, please slide forward a bit so Ginney can see the TV. She's been staring at your bottom throughout this procedure, now it's time for her to study her own."

Martha slid forward a bit, placing her nose right in her stepdaughter's fragrant cunt. Nurse Alcott switched on the TV and Ginney could see that the camera was currently pointed right, giving her an excellent view of her upturned legs and exposed crotch. She could see the end of the enormous proctoscope sticking out of her distended asshole and her mother's face covering her pussy. Ginney got even wetter seeing herself like this and couldn't believe how strange the tube looked in her ass. She felt a strange surge of pride well up as she noted her ability to accommodate such a large object in her bottom.

Ginney watched on the TV as Nurse Alcott began removing the proctoscope from her rear end. She did this at an agonizingly slow pace, making Ginney feel every inch of the huge glass rod.

Once the last of the rod finally passed through Ginney's sensitive anal ring, Nurse Alcott said to Martha, "Nurse, please verify that the patient's anus is ready for this procedure before we begin."

Martha wiggled even further forward from her position on top of her stepdaughter's nubile young body. As she did this, Ginney felt Martha's bare tits rubbing against her upper pussy area. She could see on the TV that Martha's tits had popped out of her top again. Once again, much to her surprise, Ginney found this strangely exciting. Partly because they felt so good as they rubbed against her clit, the turgid buds of her stepmother's ample tits meeting the throbbing bud between her legs. Her stepmother seemed to be giving each tit several turns down there as she squirmed around. Ginney assumed that she was trying to get into the proper position to view her asshole.

Martha rested her chin at the bottom of Ginney's pussy. Her eyes and nose were now practically touching her stepdaughter's puckered rosebud. Martha inhaled deeply, enjoying the musky scent of Ginney's ass. She was happy to see that Ginney's asshole was still distended a full 1 1/2 inches. The sexy opening throbbed enticingly as Ginney's sphincter muscles tried to return the stretched hole to its normal closed state.

"I'd say the patient is definitely ready, doctor," Martha said from her position between Ginney's upturned legs. "Her asshole is wide open. In fact, it's positively gaping."

"You're right, nurse. It is open rather wide indeed," replied Nurse Alcott. "Although given my extensive personal and professional experience, I wouldn't exactly call it gaping. In fact, this is actually the MINIMUM amount that Ginney's asshole should be dilated before performing this procedure. If you ever feel the need to open her asshole wider than this, by all means do so. It is much, much better to open it too wide - if there is such a thing - than not wide enough. You can't be too safe, you know. Also, feel free to use whatever means necessary to distend the patient's anus the desired amount: dilators, a speculum, your fist, whatever strikes your fancy. Of course the most effective solution is a combination of many different anal stretching techniques, so that is usually the most desirable approach."

"Don't worry, doctor. I'm sure I won't have any trouble remembering to do THAT," Martha replied. It was so much fun talking about stretching Ginney's sexy little asshole right in front of her like this. Martha wondered what unsettling thoughts were running through Ginney's head during this rather embarrassing discussion. She hoped that Ginney was at least getting the hint that this was not the last time she would have to endure this procedure. Soon this lewd invasion of her bowels would become as familiar to her as her enemas.

Martha couldn't resist taking some deep breaths and blowing a couple of times directly into her stepdaughter's open ass. She was gratified to hear Ginney moan audibly from the delicious tickling sensation this created in her sensitive bottom. Martha smiled as she wriggled her way backwards a bit, giving Nurse Alcott access to Ginney's yawning anus.

"Here we go, Ginney!" Nurse Alcott announced as she pushed the small end of the rubber tube easily through Ginney's wide open hole, beginning its long, slow journey into the deepest reaches of Ginney's exquisite behind.

"Are you watching your bottom on the TV?" Nurse Alcott asked Ginney.

Ginney could clearly see the pink, glistening flesh of her rectum and colon magnified considerably on the big screen TV above her. "Wow, that's what my bottom looks like inside?" Ginney thought. It didn't look anything like she had expected. "You know, it's actually kind of pretty," she mused, which caused a warm pleasant feeling to spread through her body.

"Yeah doctor. I can see everything very clearly," Ginney replied with a hint of excitement in her voice.

"Excellent, Ginney. Now keep watching. You should give your bottom your full, undivided attention throughout this procedure. It will be wonderfully educational for you. The more you know about your bottom, the better, so study it carefully. I know I certainly will be."

"Sure, doctor."

Ginney shifted her gaze from the monitor to her stepmother's tight rear end. Martha's daisy duke style shorts had worked their way even farther into her asscrack. About half of Martha's bottom was completely exposed, revealing the lovely dimples on the side of each asscheek. "I wonder what MOM'S bottom looks like inside?" Ginney thought devilishly. For some reason she didn't understand, Ginney's mouth began to water.

Nurse Alcott felt some resistance as the tube reached the first twist in Ginney's intestines. Now it was time to find out if the thick rubber tube was bendable enough to make the turns in Ginney's bowels. If not, Nurse Alcott would MAKE it work somehow.

She tried twisting the sigmoidoscope as she normally did with Ginney's enema tubes, but it wouldn't budge.

"Oww!" Ginney yelled as the hard rubber tube tried to force its way up her sensitive bottom.

"Now Ginney, I need you to cooperate with me here," Nurse Alcott said. "You just need to relax like you do for your enemas. Nurse, assist the patient by rubbing her bowel area."

The brief pain Ginney had experienced when Nurse Alcott tried twisting the tube was also accompanied by intensely pleasurable sensations. These feelings were enhanced as her stepmother began to rub Ginney's clit with her well-trained fingers. Ginney decided that a bit of pain was well worth the incredible amount of pleasure the tube was producing in her young bottom. She was determined to take the entire 50-inch length up her ass.

Ginney concentrated all of her energy on allowing the tube to get beyond the blockage and deeper into her hungry ass. After several long minutes of straining, grunting, and groaning from Ginney, and some really hard thrusting of the tube, it finally broke through the blockage. Ginney gasped with pleasure as the sigmoidoscope invaded her bottom further, advancing forward into the next portion of her rear. She was very proud of her accomplishment.

Nurse Alcott realized that inserting all 50 inches of the tube was not going to be easy. Both she and Ginney had to use every once of determination they possessed just to get it past the first major turn. Nurse Alcott knew that the same monumental effort would be required for every single turn in Ginney's bowels.

However, Ginney was more than equal to the task. She couldn't believe how heavenly the tube felt in her bottom. It was even better than the 30-inch colon tube that was often used for her enemas. The thicker rubber and ribbed surface of the special sigmoidoscope created much more intense sensations in her bottom than the colon tube ever had. Being much wider, the sigmoidoscope also filled her intestinal tract completely, rubbing deliciously against the sensitive walls.

The sensations became even more intense once the tube invaded the virgin territory beyond the 30-inch mark. This combined with the erotic view of her own bottom on the TV sent Ginney into a sexual frenzy.

"Yes, nurse!" Ginney exclaimed. "MORE, I can take MORE!...further...mmm...ooooh!...push harder!...God this is good!....NEEEED...I NEED M...M...OOOOH...SO FULL...MMMMM....NEEED MOOORE..."

Periodically, Nurse Alcott stopped jamming the tube up Ginney's rear and paused to make phony notes on Ginney's chart. This was simply to maintain the charade that this was a real medical exam.

Ginney found these pauses agonizing - her body ached for more of the tube. She squirmed in frustration on the table, while Susan pretended not to notice and continued scribbling gibberish on Ginney's chart.

It was a good half hour before the tube finally reached the 50-inch mark.

"That's it, dear. It's in all the way," Nurse Alcott announced.

Ginney was a bit disappointed to hear this, but also extremely proud of her accomplishment. She had never felt so incredibly full in her entire life. She had also never felt so incredibly good in her entire life. Her training was constantly bringing her new levels of sexual pleasure. Prior to the onset of her training, she never would have dreamed that such enjoyment could be derived from sticking objects up one's bottom. Of course she had played with her anus a bit out of curiosity prior to her training. What young girl didn't from time to time? But it was nothing like this. Her stepmother and school nurse had introduced her to a whole new world of sensual delights. A world most people never get to experience. As she lay there with 50 inches of thick rubber buried deep in her ass, Ginney felt like the luckiest girl on earth.

"Ok Ginney, now comes the most important part," said Nurse Alcott. "In order to dislodge any harmful bacteria, I'm going to have to move the sigmoidoscope back and forth in your bottom like I did before."

"OK, doctor!" squealed Ginney with unconcealed delight.

"Nurse," said Susan, "make absolutely sure you massage the patient's bowels during this part of the procedure."

Susan grabbed the end of the tube protruding from Ginney's bottom and pulled out hard. She paused once about a foot of the black rubber was exposed, the copious lubricant causing it to glisten menacingly in the light. Susan admired it for a moment, then quickly slammed the tube back into Ginney's ass, getting her whole body into the motion in order to generate as much force as possible.

"OOOOOOHHHH...MY...GAWWWD!" Ginney bellowed at the top of her lungs. Her entire body was rocked by the impact of Nurse Alcott's incredible hard thrust. The feeling as all 50 inches of the hard rubber tube slammed hard into her bottom was indescribable.

Beads of sweat formed on Nurse Alcott's brow as she continued to slam the tube into Ginney's hot ass with all her might, her shoulders running into Ginney's upturned legs at the end of each thrust.

"OOOHH ... OOOOHHH .... YES ... NURSE! ... MOM! ... THANK YOU! .... MMMMM ... HARDER! ... PLEEEASSE ... STICK IT IN DEEP!" screamed Ginney as her entire body trembled with pleasure. Finally she had found something big enough to fill her hungry ass. And the harder Nurse Alcott slammed it into her spicy behind, the better it felt. "Now if I could just do this with the nurse's sexy hand..." Ginney thought. She was determined to take Nurse Alcott's hand farther up her bottom at the next opportunity.

Ginney hoped this hard reaming of her bottom would never end, but eventually she lost control. She orgasmed violently, screaming so loud that Martha and Susan were forced to plug their ears. Ginney's body spasmed forcefully, almost knocking Martha off of her. But her stepmother managed to stay on top of Ginney despite the wild ride, never letting her hand stray from the young schoolgirl's clit. Ginney passed out after several minutes, her body overcome with pleasure.

The room was completely silent in the wake of this highly successful procedure as the three women tried to recover from the experience. They were all drenched in sweat and breathing heavily as if they had just run a marathon. It was several minutes before any of them were able to regain their composure.

Martha made the first move, getting off of Ginney and walking over to stand next to Nurse Alcott. For the first time in several hours Ginney was able to see something other than either her stepmother's rear end or the inside of her own.

Now that her arousal had faded, the huge sigmoidoscope jammed in her bottom actually began to feel very uncomfortable to Ginney. She felt a growing pain throughout her bowels. Her anus hurt especially bad, as the poor hole had been forced to remain open a full 2 inches for several hours. As she lay there, Ginney wondered why Nurse Alcott still hadn't removed the sigmoidoscope from her sore bottom.

Ginney could hear Nurse Alcott and her stepmother discussing something in hushed tones. Both of them sounded very concerned about something.

"Mom! Nurse!" Ginney called out, "this is really starting to hurt."

Neither her stepmother nor Nurse Alcott responded to her plea. They continued on with their discussion for what seemed like an eternity to Ginney. She felt completely helpless as she lay there with her feet still locked in the stirrups. All she could do was wait.

Finally, Nurse Alcott's head appeared between Ginney's upturned legs.

"I'm afraid I have some bad news, Ginney," Nurse Alcott said. "Due to your continued use of the filthy school toilets despite your mother's warnings, you have contracted a bowel infection."

Nurse Alcott paused for a moment to let this sink in before continuing. "This should be treatable without hospitalization, but I still need to determine which type of treatment would be best to cure your particular case. At any rate, I'm afraid I'm going to have to ask you to cancel any plans you might have for tonight; your bottom may require further medical attention at home this evening."

"My God!" Ginney thought, "This is getting ridiculous. There's no way I can take any more of this today. My bottom needs to rest at some point!"

Nurse Alcott was pleased to see from the expression on Ginney's face that she has succeeded in scaring her a bit. This would keep Ginney on her toes tonight and most importantly, keep her thoughts focused on her rear end.

At this point Nurse Alcott decided to give Ginney some relief and finally started to remove the sigmoidoscope from Ginney's ass. But just to frustrate Ginney a bit further, she did this at an agonizingly slow pace.

Ginney gave an enormous sigh of relief once the last of the huge rubber tube finally exited her body.

Nurse Alcott then unlocked Ginney's legs from the stirrups and told her to sit up. Ginney was shocked to see that the clock on the wall said it was almost 4pm. She had been in the nurse's office for almost 4 hours! The time had absolutely flown by. That almost always seemed to be the case with her exams, but they had never run THIS long before.

"Don't worry, dear," Martha said. "The nurse will write you an excuse for the classes you missed today. What we were doing in here was much more important anyway. What classes did you end up missing?"

"Math and Chemistry," Ginney replied, wrinkling her nose in disgust.

"Yuck!" replied Martha. "Well a pretty girl like you doesn't have to worry about that stuff anyway, Ginney."

Ginney beamed at her stepmother's compliment.

"I have your panties, dear," Martha said, holding up the frilly white garment. "Why don't you get down from there and I'll help you put them on. But watch your step; you made quite a mess on the floor."

Ginney blushed deeply when she saw the large puddle of lubricant and pussy juice that had collected on the floor in front of the exam table.

Ginney's legs had fallen asleep after being nearly vertical in the stirrups for 4 hours. Nurse Alcott took her hand and helped her climb down gingerly from the exam table.

Martha got behind Ginney and told her to lift first one leg and then the other so she could slide the panties on. Martha took her time with this, inching the panties up Ginney's long legs slowly so she could enjoy the silkiness of her stepdaughter's perfect skin. She paused when she reached Ginney's ass.

Martha lifted up the young schoolgirl's plaid skirt and stuck her head right up there, bringing her face within inches of Ginney's lovely bottom. Ginney could feel her stepmother's hot breath on her sensitive anus and pussy. After a long moment, Martha pulled Ginney's panties up the rest of the way.

Ginney was pleasantly surprised to discover that the large blob of lubricant goo from this morning was still in the seat of the panties. It felt absolutely delicious when, as a final touch, Martha wedged the gooey panties into Ginney's pussy and asscrack with her fingers.

"There we go, nice and snug," Martha said, grinning in Nurse Alcott's direction.

"All right, now run along, dear. We wouldn't want you to miss your last class today, too," Martha said, giving Ginney a wink and a final pat on the bottom.

Ginney kissed her stepmother and said goodbye to the nurse, and then hurried off to class, enjoying the squishy sensation of the goo in her panties as she walked with an extra spring in her step and sway of her ass.
