Part 1

Gwen sat quietly in the car as it whizzed down the freeway. It was just starting to turn dark and she wondered what the evening had in store for her. Her life had been a whirlwind of confusing emotions since she had answered that personal ad on the bd/sm website several months ago. She was always fearful at the start of these adventures, but always, always ended up doing as she was commanded and totally loving the wide range of physical pleasures that arose from them.

Tonight she really had no idea of where they were headed. Her Master had simply told her to dress or undress as the case may be. She wore just a leather collar, thigh high stockings and high heels covered by a long coat. His favorite outfit. He kept saying how much he appreciated the idea that she had given him for this, but really, she was in a fog as to what that could have been.

They turned off the freeway and headed towards the hospital area and Gwen wondered if she was once again going to be made to publicly exhibit herself for his amusement. She could still remember the shame and embarrassment that she had felt when total strangers had been allowed to look at her naked body as she stood on the street corner flashing them. Plus the adult book store. Not to mention the afternoon he had spent driving around the city with her sitting naked in the seat next to him. And the public scenes at the various play socials they had attended.

Not that it hadn't all been exciting!

Finally, he turned into a small parking lot and headed towards some offices at the far end.

"I just bet you're wondering what we're up to tonight, slave?"

"I'm here to please, Master."

"Hehehe, true. But I did appreciate your telling me a little dream that you had about your doctor a few months ago. It made me wonder what would happen if you had to submit to a more perverted physical exam by a professional. So I posted some messages on the net and interviewed a few people and found what I think will be an interesting partner to give you a most thorough exam tonight."

Interesting? Gwen's stomach clenched in fear as her mind flowed through the various tortures that he could devise in such a setting.

"Come on, get out of the car and let's go."

So she did and stood for him beside the car door as he came around and snapped a chain leash to her collar to lead her across the parking lot to what appeared to be family practice offices.

They walked up to the door and knocked. A nurse came to the door and let them in asking them to have a seat and the doctor would be with them in a minute. Only a ghost of smile flickered across her face as she took in the dog collar and leash on her new patient. Then she shut the door and locked it behind her as she obviously was leaving for the day.

"Take off your coat and hang it up, dear."

Gwen did as instructed taking her seat afterwards. She couldn't help, but send a glance to the glass door that looked out on the parking lot knowing that she could easily be seen in the brightly lit waiting room. As usual, she felt shame and humiliation, but also the deep excitement that was welling up inside causing her nipples to grow hard and her cunt wet.

"Mrs. ________, I'm ready for you now. Please come on back"

She was a small thin woman with short gray hair wearing a face mask and a white lab coat. Gwen and her Master followed her back to an examining room.

"Just hop on up here, dear and we'll get started."

Gwen did as she was told and laid her head back on the cushion placing her feet in the stirrups that had been stretched out from the end of the table. The side arms had been pulled out from the sides and quickly Gwen's arms were fastened tight to them followed by her ankles being tied to the stirrups until she was unable to move.

"Your Master and I have discussed what he wants done to you tonight and I expect you to behave and obey."

Saying that, she removed her lab coat and Gwen gasped as she looked at her.

Obviously, this was a woman as perverted as her Master. Large gauge nipple rings adorned her small and perky breasts, and there appeared to be a small circle of puckered scars around her aureola from repeated play piercings. But Gwen was astonished most at the size of the padlock that perforated her inner labia and stretched them down a few inches.

"Like the looks of that, do you? Well, maybe later, but for now, let's make sure you're nice and healthy."

With that, she pulled on a pair of latex gloves and gave a soft chuckle as she moved towards her.

Part 2

She grasped Gwen's ankles and made her scoot towards the edge of the table so her ass almost hung off the edge. Then quickly, she reached into a pan on the counter and deftly inserted a bulb thermometer deep into Gwen's rectum.

"We need to check that temperature, dear."

While she waited for that, she used her stethoscope to listen to her heart and lungs. Without bothering to warm it, of course.

"That sounds just fine, now let's see, your temperature looks normal so let's get you ready for your other tests."

Ready?

This time she brought out a huge speculum and lubed it up before forcing it into Gwen's spasming cunt. Before she had time to acclimatize herself to the feel of it, the kinky doctor had started cranking it wider and wider so Gwen could feel the pressure start to build as her pussy was forced to open. The doctor kept at it until a low moan escaped Gwen's lips signifying her submission to the tool.

Since her eyes were closed, Gwen only heard the ripping of cellophane and then felt fingers as they explored her cunt. Then she felt an unusual feeling as she realized the doctor was inserting a catheter into her urethra.

"Does that feel nice, slave? We need to take a urine sample so hold still."

Gwen could only lay there and feel the tube slide deeper until it finally penetrated her bladder and she felt the release as it was drained into a bag the doctor was holding.

It was humiliating to lose such control of one's body, yet Gwen felt the excitement start to build once again as she could look over and see the proud smile on her Master's face as she submitted to this perverted medical exam.

"We'll just leave that there for a minute to get every last drop. Now it's time for a blood sample."

She picked up the long piece of rubber that was used to make a tourniquet, but instead of wrapping it around Gwen's arm, she began at the base of her right breast, which she stretched out by fiercely tugging on her nipple and raising it to the ceiling. Then she stared started binding her breast tightly at the base forcing it to stand up and stick out. She completed the same task with the other one, then started slapping them with her gloved hands. Hard!!

Raising the head of the table, she moved Gwen into a sitting position, then once again went back to her little pan of goodies and removed a large needle. Without warning at all, she simply unsheathed it and inserted it deep into Gwen's tit near the nipple. Despite the whimpers that were coming from the slave's mouth, she continued until there were 4 of them placed prettily around each nipple.

Then picking up a small collection bottle, she pulled out all of the needles on one breast, placed the bottle so the mouth of it surrounded all of the puncture holes and started squeezing her breast to force the blood out so it would fill up the bottle.

Oh God, that hurt! The feel of the needles was bad enough, but then to squeeze them hard enough to make them bleed and drip like this was excruciating.

The doctor completed the same technique with the other breast until she declared herself satisfied with the results.

Placing the beaker on the counter, she paused to turn the screws again on the speculum to force Gwen's cunt even wider, then grabbed the tube protruding from her pee hole and swiftly pulled it out.

Ooooooh, that felt so strange thought Gwen. But nice too!

Again the doctor cranked the speculum even wider and as she looked down at her panting patient, she slowly began to lubricate her gloved hand.

"Now, you know you must have a thorough pelvic exam, right slave?"

So she quickly undid the metal instrument invading her cunt and placed her closed fist at the entrance to Gwen's pussy and started pushing. Since Gwen had been trained to take her Master's fist, this was not a problem and slowly the doctor's hand disappeared into her cunt. Once it reached the wrist, she quickly began rotating her closed fist inside the now sweating slave's cunt while her other hand palpitated her abdomen.

"Yes, everything feels just fine, don't you agree, slave?

Oh yes, it feels more than just fine, thought Gwen as she nodded her agreement and allowed the flood of sensations to wash over her. The doctor was now establishing a rhythm and occasionally, darted her head down to lick at Gwen's rock hard clit.

In the haze of her pleasure, she noticed that her Master had unzipped his pants and the good doctor was using her best bedside manners to stroke his hard cock with her free hand keeping time with Gwen's own pulsating pussy.

As the two of them grew closer to their separate orgasms, her Master reached over and picked up a pair of forceps and without warning, grabbed each nipple and begin twisting the throbbing nipples until Gwen started screaming her orgasm.

As she returned back to reality, she looked over and watched as the doctor finished her services to capture Master's seed in another specimen cup.

Finally, the doctor put away the specimen cups and reached into a cabinet and pulled out a couple of bags of liquid.

Gwen could read the writing that declared them to be 100% saline. Quickly, the doctor hooked IV lines to them, then reaching into a drawer pulled out what appeared to be large gauge needles and alcohol swabs.

"Your Master has decided that your breasts aren't large enough for him to display you at the next play party."

Not large enough!! These DD size breasts had been literally a pain in the neck since she was 15.

"So he requested that I enlarge them with a few hundred milliliters to see how they look."

With that, she tore off the protective covering of one of the needles and approached Gwen with what appeared to be a very wicked gleam in her eye.

Part 3

Using her teeth to tear open an alcohol swab, the doctor approached Gwen and quickly rubbed down both breasts. The cool evaporation of the liquid made her nipples harden up.

Then without warning, the doctor pinched a piece of skin and stuck the needle straight in Gwen's tit.

Aaaaaaah! She closed her eyes against the sting, then looked down as the valve was opened and she felt the pressure begin to build in her breast. In seconds, a small bulge started to form around the needle and once she was satisfied with it's appearance, the good doctor removed the needle and inserted it in another spot to continue pumping up Gwen's breast.

It seemed like an eternity, but must not have been that long before her breast began to grow and Gwen felt the pressure of the fluid. The doctor changed bags and then proceeded to duplicate her efforts on the other breast.

As always Gwen's body betrayed her and her pussy began to moisten once again. Her nipples were throbbing from the discomfort that she felt, but she knew that deep inside she was enjoying herself as always. Judging by the way the doctor kept fingering her pussy and her Master stroked his cock, they were having a good time as well!

Finally, the pervert doc was satisfied with the appearance of her now huge tits. She removed the needle and then squeezed Gwen's tits smiling as blood and water oozed out.

"Get up on the desk."

"What?"

SMACK!!

Her Master had been speaking to the doctor and her slowness in obeying had earned a swift punishment. After that, she literally jumped on the desk and laid back exposing herself for his attention.

Pulling on a pair of rubber gloves, he changed the needle that was hooked up to the last saline solution. Then forcing the doctor's legs wide apart, he swiftly plunged the sharp point deep into her outer labia.

Gwen watched as the doctor bit her lip to keep from crying out and then watched astounded as the woman's cunt lip grew and grew. Her Master kept using the needle to inflate the women's lip to grotesque proportions. Then continued with the other side.

Once he was satisfied, he quickly wiped off the blood and saline displaying the woman's distended labia.

Then reaching over into a drawer, he pulled out a packet of oddly shaped, curved metal rods. Taking out one that was the size of his index finger, he slowly lubricated it up with some sterile jelly, then bent down to the doctor's vagina.

Gwen watched as he spread the woman's swollen lips and found the small opening to her urethra, then slowly forced the huge intruder inside.

The doctor gasped and whimpered as the metal rod stretched her tiny hole and yet, it was obvious that she was enjoying her humiliation as well. And with a final push from him and a shudder from her, the rod slid home.

Her Master then used more jelly to smear over both of his latex covered hands, and started inserting the fingers of his left hand inside the doctor rubbing against the metal rod still inside of her. With his other hand, he started playing with Gwen's pussy as well.

Somewhere during the evening, Gwen's hands had been freed so as she enjoyed the pleasure of her Master's attention her hands started caressing her swollen tits and squeezing her rock, hard nipples.

She had been well trained by her Master to take huge objects, so in minutes his fist was sliding in and out of her gushing cunt. And the same was true of the pervert doctor. She laid back enjoying the intense pleasure she must have been feeling by the constant friction of his knuckles as they slid past her now fat lips and the metal rod penetrating her bladder.

Gwen had been tormented and played with for too long tonight and as she pulled hard on her nipples and stretched them to the ceiling, she raced towards her long delayed orgasm. She heard the doctor coming as well as she continued to mercilessly jiggle her swollen tits by her nipples and screamed her orgasm out loud.

As she slowly came back to reality and caught her breath, she heard his fist as it popped out of her gaping hole. The emptiness she felt was balanced by the fullness of her breasts still filled with the saline and feeling twice their normal size.

She looked over as her Master removed his hand from the doctor's cunt and then slowly removed the curved metal rod from her urethra followed by a gush of urine onto the tile floor.

Geez, what a sick person I am!! But even as she had that thought, she knew that she would be back for more.

Part 4 ?

Gwen pulled into the parking lot of the hospital. She was early for her appointment, but that was her always eager to please.

Her Master had made the mammogram appointment for her saying that she needed to have them checked after the many months of abuse that he aimed at them. Not that she didn't enjoy it too!

She had been here before so she quickly made her way down to the x-ray department, checked in and sat back to wait. As always her mind wandered and she dipped into her fantasies. She felt a little nervous after her experience with that sadistic doctor, but this was a hospital and should be a piece of cake after that ordeal.

Finally, her name was called and she followed the cute little brunette back to the room. She was told to undress completely which was a little strange, then the nurse gave her the teeny gown to cover herself with and said the doctor would be with her shortly.

After the door was closed, she heard the lock turnover and that's when she started worrying.

It seemed like as if she had been waiting forever, but she knew it couldn't have been that long. Finally, the lock clicked again and in walked the sadistic bitch who had tormented her those many months ago.

She gave Gwen her wicked little smile and handed her an envelope. Inside was a message from her Master telling her to be obedient and not disappoint him.

Looking at the other woman, her head gave a slight nod indicating her understanding and that she would obey her.

Reaching into a drawer, the doctor pulled out a box of gauze and some medical tape. First she taped over Gwen's mouth, then using the gauze, she made a wrap around Gwen's head and mouth so she looked like some sort of accident victim with only her eyes and nose visible.

Next, the doctor took Gwen's wrists and using more tape fastened her to various appendages of the x-ray machine so her large breasts were just at the right height to be crushed.

Gwen had had her breasts x-rayed before and knew how uncomfortable it could be. Her mind raced through the sadistic possibilities of what might happen now.

Reaching underneath a large cabinet, the doctor pulled out 2 flat plastic sheets. She held them up so Gwen could look at them closely and she gasped as she understood there was dozens of small little, pointy and sharp protrusions dotting the surface of each. She could only imagine the pain that would cause once the two sheets were placed in the machine and screwed down tight on her soft tits.

The plastic sheets were placed on the large vice like arms, then the doctor lifted Gwen's right breast and held it in place as she moved the sheets closer together.

Gwen could feel the sweat start to trickle down her forehead as she waited in anticipation of the torment that was coming. She could feel the pinpricks as the little points touched her skin, then felt more pressure as the sadist continued to move the arms and crush her breast between them.

She had rarely felt so helpless, she knew that she could move or she'd rip her skin on the protrusions and anyway, her bound arms and hands kept her perfectly still as the machine whirred some more and she felt the sting as the sheets mashed her breast flat.

Well, not quite. Once the machine stopped Gwen peeked down and realized that despite the crushing pain she felt there was still a few inches before the two sheets would have touched each other.

"This is a variation of placing a thin piece of wire in a suspicious lump for a lumpectomy. There'll be no wire left behind and I'm not using any numbing agent, but I thought this might prove fun."

She proceeded to use some kind of disinfectant on the part of her breast that was visible and then finally, opened up another drawer and pulled out some long and rather large looking needles.

Gwen bucked and tried to scream through her gag. She could remember the last time this bitch had played with her, but she knew she couldn't stop what was happening.

Her eyes were riveted down and she watched as the tip touched her skin, then slowly disappeared into her breast. Incredibly, this caused such a wave of heat and pleasure to rush through her body that Gwen couldn't stop the low moan that erupted.

The doctor just chuckled and reaching down toyed with Gwen's moist snatch and hard clit. Then she picked up another needle and repeated the procedure on the other side.

"One last one, then we can take the picture."

This time she placed the sharp point against the tip of Gwen's hard nipple and started pushing it in.

Aaaaaaaaaaagh!! Even muffled, Gwen;s scream was plenty loud. But to no avail, the doctor continued until most of the foreign object was buried in her tit.

Going behind the screen, Gwen barely heard the click and whir of the machine as she took pictures of Gwen's tortured breast.

Then the doctor came around and start freeing Gwen's breast.

"Now the other one."

Everything was repeated again as she skewered Gwen's left breast. Gwen started floating somewhere in there and it barely registered what was happening to her. But finally, she looked down and realized that she had been freed from the machine and her hands were able to softly touch and caress her breasts being careful not to disturb the metal sticking out of them.

Taking up some gauze, the doctor swiftly pulled out one of the needles and holding the gauze tight, waited patiently for the bleeding to stop. She continued until only the ones in her nipples were left and naturally, she took her time removing those slowly so Gwen could feel every nerve ending protest.

Once done, she helped Gwen put her hospital gown back on and then placed Gwen in a wheelchair and left the room saying she'd be right back.

She was true to her word and came back in saying the pictures looked perfect and they would not have to repeat the procedure.

Repeat? Gwen could only shake her head in disbelief.

Since she was still in a daze, she was only vaguely aware when the good doctor started using tape to fasten Gwen's wrists to the arms of the wheelchair.

Taking a heated blanket from somewhere, she placed it over Gwen so she was covered up and the bondage didn't show.

"Now let's go for a ride."

Part 5

Gwen could feel the palms of her hands get sweaty as they approached the medical park and drive through it to their destination. She could clearly remember her last visit to the cruel and sadistic "doctor" that Master had brought her to for her last yearly exam. She even felt a tiny prick of pain in her breasts as her mind flashed back to the painful mammogram the doctor has subjected her to at the hospital.

But a year had passed and now her Master had decreed that it was time again for a yearly physical to make sure all was well.

She had been new to the lifestyle back then, but now being driven to a strange destination knowing that she would be the object of various pain and tortures no longer scared her. It just made her wet and excited and she realized that she had become the total slave that her Master had predicted she would be so many months ago.

As they walked to the building, she felt a slight chill between her legs as the breeze wafted up her skirt to her naked mons. She was freshly shaven as always and her large breasts jiggled and bounced as they entered the waiting room and took their seats.

In the waiting room, she looked around at the other women and couldn't help but wonder if they too would be victims of the sadistic doctor or was it just she that enjoyed such "intimate" exams.

Finally, the nurse called her name and back she went. Once in the examining room the nurse looked at her records, then told Gwen to strip naked. A perverse smile crossed her face and Gwen knew that she would have a larger audience today.

Finally, the doctor arrived and she and the nurse both donned their rubber gloves. Telling Gwen to lie back and spread her legs, her feet and hands were immediately fastened tight by the attractive nurse and in minutes the good doctor had inserted her hand deep inside Gwen's spasming cunt checking for irregularities. Then she stood back and told the nurse to do the same.

Gwen's face turned red as the young woman twisted her fist and felt around per the doctor's instructions looking for any abnormalities, Then Gwen felt the twinge at her anus as the woman slipped a finger in her now tight asshole and continued to insert more fingers with a generous portion of lube to help find her way in and incredibly, Gwen felt the nurse's tiny hand slip inside and then she proceeded to fist fuck her anus and pussy at the same time.

Gwen could only look over at her Master's satisfied smile and think back on the many hours he had spent using various huge dildos and large objects to get her to this point of depravity.

Just as Gwen thought she would lose total control and orgasm, the nurse slowly withdrew her hands and pronounced herself satisfied with Gwen's anal and vaginal health.

"That's good to hear, now those breasts of yours need some special attention today."

Oh, Gawd, Gwen could only imagine what that must mean as she recalled the last time they had been the object of th doctor's attention.
