In the meantime, somehow he had attached the big vibrator to the thing in my ass, and it was starting to hurt. I didn't know what to do. I was completely helpless, and I wanted to cry. It was a different kind of pain - sharp rather than dull, but not the kind that makes you sick. Maybe it would be alright when I got used to it. I closed my eyes and started to whimper like a baby. Every few seconds I'd feel an involuntary muscle twitch. I wasn't sure what part of me it was. I was stuffed so full nothing felt normal. Maybe it was my abdomen. The twitches were getting stronger. A muscle would quickly clench and release - or a little shock would shoot through my pelvis.

The doctor was now abusing my clit with the little vibrator, pressing it into my flesh and shaking it rapidly. The spasms came quicker and I knew I was in for it. My little cries became a long low growl and my body tried with all its strength to straighten itself, first with quick pulses and finally with one long super human effort.

As I went limp I thought about the strong leather straps which were keeping me at once doubled up and spread apart.

I watched the doctor slowly remove the stepped dildo from my ass. At the moment I had no feeling there. I was quite sure my poor anus had never passed such a test before. The size of the thing that came out was still a shock to me, and I wondered how long it would take me to return to normal. I could just barely see the muscular ring around my opening, and it looked red and swollen. It seemed to me as if it had not yet fully closed.

The doctor walked to the refrigerator and opened the door. "Care for a Coke, Teresa?"

"No thank you, Sir." He walked back to the table and poped open a can. He had something else in his hand. He took a long drink and then placed the cold can against my sore anus. "Can you feel this, my dear?"

"Yes, Doctor, but it feels strange. It doesn't feel normal." I watched as he lubricated another dildo. It appeared to be made of aluminum, or some other shiny metal. "Please, sir. Not again. I'll never be the same."

"This will go in easly." I felt nothing. I watched him slip it all the way into me until the lip on the end would let it go no further. He then turned his attention to the monster in my vagina, applying pressure to force me to accept the final increment in size. This one also was pressed into me until the stop ring pushed into my vulva. The ring had a relief at one point to permit free access to my clit. Also, I had failed to notice before that this thing had a cord attached to it.

"Teresa, did you notice how easily your vagina expanded after the orgasm?"

"Yes, Doctor - But listen, I'm starting to feel cold. I don't know. I think my bottom."

"Yes, my dear." He clicked a switch, and the monster in my pussy began to move. It was not a regular motion - not a vibration - more as if something inside wanted to get out, knocking irratically against the casing.

"Doctor, I think it's getting colder - in my bottom."

"Teresa, I want you to explain to me again how you happened to get the package."

"Maria got it this noon from her aunt's house. It was taped up, just the way I gave it to you."

"My dear, that makes no sense at all." He walked to the refrigerator again and opened the door. The thumping of the thing in my vagina was getting all my attention for the moment. In a way I was glad, because it seemed to relieve the discomfort of my stretched openings.

The doctor came back with a small leather case. "What's your relationship with Maria's brother?", he asked me.

"She introduced us one time at a Christmas party, sir. Really, he's way too young for me, if that's what you mean. But I thought he was a good-looking guy."

"What about your business relationship?"

"I don't know what you're talking about. - Doctor, the thing you put in my bottom - it's metal, isn't it? - I mean - I mean, instead of warming up, it seems to be getting colder. It's starting to burn my anus."

"Your feeling is coming back, Teresa. We'll deal with it in a moment. But I need you to tell me how much he's paying you." He opened the little leather case and took out a small shiny curved metal rod. "I'm not a stupid man, Teresa."

"I understand that, sir." After a moment I felt something strange near my clit. "I think you have the wrong idea, Doctor. I'm just a - - sir, I - I don't know what you're doing, but - but it hurts."

"I'm going to ask you very simple questions. How long have you been working with Maria's brother?"

"Shit! That thing feels cold. What are you doing to me? - And that thing in my ass - it's hurting more and more. It's burning my anus, Doctor." This was too much. It felt like he was sticking a hot needle through my clit. "Doctor, you promised not to injure me or cut me. Are you cutting my clit?"

"I'm not touching your clitoris, Teresa." Ahh, I finally realized. He was sticking something up my pee hole.

"This is crazy! I've never had anybody put anything in there before. Why does it have to be so cold, Doctor?"

"I just need to get your attention, my dear. There will be no injury. You can be sure of that."

Now that I understood what was happening, it made more sense. He opened the case and removed a larger one. I felt the first one being withdrawn. I knew it was very smooth, but it felt like it had barbs on it. What's next, Doctor, are you going to stick something up my nose?"

"I'm not that kind of a doctor."

"That's a joke. What kind of a doctor are you, anyway? - Damn! why does that thing in my ass keep hurting worse and worse? All the other pains seemed to go away after awhile. It's burning me alive."

"I think we can come to an understanding here, Teresa - something that will benefit both of us." He started slowly inserting the larger curved rod into me. It felt colder than the first one, probably because the first one had already cooled off the pathway. I don't know if he was using lubricant. It sure didn't feel like it. "I don't like this, Doctor. Something feels wrong about it. And you're hurting me."

"I can assure you, you'll be alright."

"And I want you to take that thing out of my ass right now."

"Or you'll do what??" I think he now had the curved rod all the way in my pee hole. It felt the worst when it was moving - both going in and coming out. "Teresa, I think you should be working directly for me instead of him. Simply tell me what your arrangements are, and I'll pay you more."

Jenny suddenly opened the door. "Doctor, Jake is bring Maria in. What do you want me to do?"

"I'll probably need your help, Jenny. I don't think Teresa knows anything."

"You know you can count on me, Doctor. I always said you should never trust Maria."

Maria was struggling as Jake forced her through the door. "Lock it, Jake," said the doctor. Jake let go of Maria and locked the dead bolt with a key. Maria stood there staring at me.

"My God, Teresa, I've never seen you like this. What's going on?" Jake took hold of her again, as the doctor carefully began removing my various and sundry insertions. Maria was no longer struggling. Jake was on one side of her and Jennie on the other. Jenny asked again, "What do you want me to do?" Jake added, "Yeah, Boss, what's the plan?"

"Take off her clothes." The doctor was finishing up with me. It felt really great to have my openings free again. He saved my pee hole for last. Actually that was the only thing that hurt coming out. He unfastened the straps on my knee supports, but of course I couldn't move.

Jake, meantime was holding Maria from behind, with his big hands cupped over her great breasts. Jenny was working on the skirt. She removed the belt and unfastened the zipper, letting the long skirt fall to the floor. I was surprised to see that Maria just let them do it. She was wearing a white half slip with an elastic waist band. Jenny pulled it to the floor, and ordered Maria to step out of the slip and skirt. Jake allowed her to take a step forward, and Jenny tossed Maria's things onto a chair.

I had been wrong about her legs. They were smoothly shaved, and quite attractive, though obviously strong. She was wearing what seemed like old fashioned undies. The black lace panties were of the full form style, and she wore an old fashioned garter belt, supporting full-length sheer nylon stockings. I was somewhat shocked.

"Where did you get those things, Maria?" I asked her.

"Oh God Teresa, I'm so sorry. You've got to help me. Can you help me please? I - I borrowed them from my aunt. You know. I just like nice things. She'd kill me if she knew. I guess I'm in a lot of trouble. You've got to help me."

With Maria's wide hips and slender legs, there was a good separation at the top. Her ample vulva made a nice bulge in her panties in the space between her legs. I wanted to see her buttocks, but she was facing me.

Jenny unfastened the garter straps, allowing her to roughly pull Maria's lace panties down to the ankles. Then she refastened the straps to the tops of the sheer nylons. "Step out," she ordered.

I wondered what I could say to cheer her up. "Maria, I had no idea you shaved your pussy. That's very sexy."

"Oh Teresa, that's not funny. Please help me."

The doctor was removing the wide leather belt from across my abdomen. My arms had fallen asleep and I couldn't move them. He kindly helped me slide back away from the end of the table and onto the raised portion, so I had a better view of what was going on. But the view was still framed by my legs, which were spread apart and still in the knee rests. My pussy was as bare as Maria's, although it was unshaved. I was really quite helpless.

"Doc, do you want us to strip her above the waist," Jenny asked.

The doctor walked closer to the group. "Let's see what we have here. Turn her around." They turned her so her back was now toward me. Jake and Jenny each had one arm. "Let's open her legs." Her handlers pushed outward on Maria's legs until she complied. The doctor put his hand in between and seemed to check her carefully. Then he got a chair and placed it behind her. "Bend her over."

He sat down and spread Maria's beautiful buttocks, continuing the examination. Jenny, I need some lube." Jenny got the tube and squeezed some on the doctor's finger. After a few moments he stood up. "She's a virgin." He continued examining her in back from a standing position. "Once more with the lube, Jenny." Jenny lubed the finger again, and I watched the doctor insert it fully into Maria's rectum. Turning it this way and that, he seemed to make a very thorough job of it. "She's in good shape. It will be fine. Leave her top on. This will do very nicely. - I like the garter belt." Jake and Jenny stood Maria back up straight again, and allowed her to put her legs together.

Then the doctor turned his attention my way. He carefully lifted each leg out of its knee support, slowly straightening it, and placing it on the narrow table. My hips objected the most. The muscles at the very tops of my legs had been stretched out of position for over an hour. He helped me swing around to the side and finally stand on the floor. But walking was out of the question. I felt light headed, my knees were wobbly, and my hips just plain hurt. "Jake, would you bring a wheel chair?" the doctor asked.

"Sure, boss, right away."

"Teresa, we made an agreement. You've kept your part, and I plan to keep mine. You'll get a nice check in the mail. Don't forget, we know where you live. We can pick you up again if it becomes necessary."

Jake brought the wheelchair, and the doctor helped me to sit down. "Just let me rest for awhile, Doctor, until I feel well enough to drive. I'm not going to leave my car here."

"Just as you wish, my dear."

I felt sorry for poor Maria, but I supposed that she was going to have to learn sometime. She really hadn't done me any favors by getting me into this. Perhaps the lesson was going to do her good. I really didn't know what she and her brother were trying to pull on the doctor, and I planned to keep it that way.

Jenny was leading Maria toward the examining table. The feeling had come back into my arms, and I tried turning the big wheels on the wheelchair to move myself a little bit out of their way. Maybe I'd stay to see if Jenny was as good as the doctor had said. Maria looked terrified. "Teresa, can't you help me?"

"You'll be alright. Just do what they tell you, Maria."

"But I'm scared. I've never been on one of these tables. And they took my clothes."

"Yes, I can see."

"And my panties, Teresa."

"Well, I lived through it," I told her. "Now it's your turn."

Jenny gave her a good hard slap on her bare bottom. "Get over there!"

"I just don't like undressing in front of strangers."

"That's okay. I understand. You may go behind the screen over there and remove them in private. I notice you're also wearing panties."

"Yes, sir, I am. They're on the outside."

"They must be removed as well. Don't put them back on. You may keep your skirt for the time being. When you've finished, come back to the desk."

I went behind the screen and slipped off my panties, hanging them over the top of the screen. I don't mind admitting I was nervous about what might happen next. I know I was sweating. I removed my skirt, making it a little easier to peel down the pantyhose. My crotch was warm and sweaty from front to back. A breeze from the window suddenly passed over the freshly exposed moist skin, rapidly evaporating and cooling the sweat. It sent a chill through my pelvis - as though my pussy and rectum were combined into one icy channel. My anus tightened. I think it sensed what was coming.

I hung my pantyhose over the screen and put my skirt back on, providing cover which I suspected would be short-lived. I smoothed out my skirt and went to take up my station in front of the doctor's desk.

"There, that wasn't so bad, was it?" He took a stethescope from a drawer and moved behind me.

"Teresa, just face this way for a moment and undo your blouse. - - - Yes, that's good. Let's check the old ticker."

After listening in four or five spots, he gave his report. "I think you're in pretty good shape. You should have no trouble handling the tests. - - - And now I need you to just sit up on the edge of the desk for a minute and pull up your skirt."

I had to hop a little bit to get my butt up on top. The desktop was hard, but I was still glad to sit. "How many children did you have, Teresa?"

"I've had three, Doctor."

After I pulled up my skirt, he reached behind one of my ankles and lifted my leg. "Your veins are still in pretty good shape." He kneeled down and checked the pulse in my ankles. "The circulation is okay - good strong pulse." He went back around the desk and got the little rubber hammer out of a drawer. "Cross your legs." He whacked me under the kneecap. "The other way." Again. "Very good. Your nervous system is in good shape. We'll have a great afternoon."

"I think I'm going to be a nervous wreck, Doctor."

"Nonsense. Face the desk again." After I followed his instruction, he moved behind me and lifted my hem, tucking it into the waist band; then he lifted the fold, and tucked that in as well. The result was that for the most part my bare bottom was nicely exposed.

"That's very good, my dear - very nice indeed. Now let's open the legs."

I guess I knew that was coming. "Like this, Doctor?"

"Perfect. Now just reach across, and grab the far edge of the desk top with both hands."

I struggled with that instruction, squatting down a bit to make it easier to reach the far edge. "This is very uncomfortable, Doctor. Don't you have an examining table, or something a little more civilized?"

"Yes, of course, but that's in the other room. You'll see later. Right now we need to make some measurements. And I'll have to ask you not to bend your knees. I want your bottom to be elevated." The doctor was beside me again, making sure my knees were straight and my feet were as close as possible to the desk.

He slid his hand down the curve of my buttocks to my vulva, and moved a finger between the minor lips of my vagina. I would have expected the opening to be dry, but something had evidently prompted my juices to flow. The finger slipped easily between the lips and thence into the opening. He didn't go deep at all, but used the finger to spread my fluid around the vulva, upward (or forward) until my clitoris too was very slippery. I was aprehensive, and my elbows hurt from the hard table top, but I felt that I deserved at least this small treat from the doctor's finger. It actually felt pretty good, and since I had no idea how long it would continue, I thought I should make the best of it. Perhaps it's a bad idea to let your enemy put his finger in your pussy, but on the other hand it's kind of erotic. Anyway, it didn't last very long at all.

The doctor returned to the front of the desk and recovered some miscellaneous items from the desk drawers. Then he placed them on a cart which was beside the desk, and wheeled the cart and his desk chair around behind me. I imagined that when he was seated, his shoulders would be about even with my anus. This was not good news.

"Teresa, I'm going to take some measurements. We'll lubricate your bottom and insert an instrument to gradually open the anus."

"Doctor, you never said anything about putting an instrument there. I don't like it. I don't want it."

" We have an agreement, Teresa."

"Why can't we have a nurse here. They always have a nurse present during examinations, don't they? The lady at the front desk seemed very pleasant. Maybe I could do it if she was here."

"That's very funny. You don't know what you're asking for, my dear."

"I don't get the joke."

"She'll have you screaming for mercy. She'll make you sing like a bird.

"But I can't sing if I don't know anything. I don't think she's going to torture me, Doctor."

"First she'll play you like a violin, then she'll make you sing."

"I don't get it."

"In the beginning she'll make you scream with pleasure. She's very good. Trust me."

"What's the punch line?"

"Pleasure can easily cross the line into pain. She knows how to read her patient. I'm doing you a favor."

"Man, this really sucks!"

The doctor lubed me up and had his finger in me before I felt a thing.

"You're a very healthy lady, Teresa. You're fortunate. At this stage I can see no reason why any form of anal penetration should be a problem for you."

"It's not the pain that bothers me, Doctor. I can stand pain. I just don't like the idea of it. I think it's very humiliating."

"That's plain foolishness, my dear. All of the organs which provide the best erotic sensations have other more mundane functions. You're just missing out."

"No Thanks."

"Okay, here's the first expander. You'll feel each step as it passes through the anal sphincter. If you think I'm goint too fast, we can rest for a moment - - but we don't back up. The instrument stays in place till we're ready for another."

"That's the other thing that bothers me, Doctor. Sometimes somebody sticks something up your ass and it doesn't really hurt - - I mean, not so bad you can't stand it. But you just want it out of there. That's all you can think about. Jeez, can't I have a pillow or something? It's my elbows that hurt; not the rest of me."

"Wait until we've put this one in all the way. Then we'll let you get used to it for a minute."

"I guess I can wait, Doctor."

"How does the instrument feel?"

"It's not what I expected. It felt cold at first. Each time you push the next step through my opening it tickles a little bit."

"We're still below the normal size. It should feel good, as long as you stay relaxed. - - Okay, this is all the way in. I'll get you a pillow."

"Thank you." The doctor came into my view as he got me a pillow out of the closet. I didn't want to try to move with that thing inside me. Actually, after being motionless for a couple of minutes I could no longer feel it. I tightened a muscle, as If I wanted to stop peeing. Yes, it was still there.

He laid the pillow on the desk beside me, and I arranged it as best I could. He next pulled the expander out of my ass and immediately replaced it with a larger version. Like the first one, it was cold going in. He had pulled the first one out quickly, and it gave me a bit of a thrill. Then the cold jab was the icing on the cake. I suppose he was right about erotic pleasure, but I always had a problem with anal sex.

He worked faster this time, not pausing after each step. He pushed it straight into me with a steady pressure, giving me a different sensation than before. It hurt progressively more, but I decided to try toughing it out to the end.

Well, almost to the end. "Can you just leave it like that for a minute, Doctor?"

"Of course, my dear. When you're ready, we'll replace it with a plug and give your anus some time to relax. We're still in the average size range, but as soon as you get used to the plug we'll forge ahead."

"I think this may be big enough for me, Doctor."

"I don't think so. You don't even have tears in your eyes."

"I didn't have tears in my eyes when I gave birth to my children, but that doesn't mean it didn't hurt like hell."

"Yes, I understand. But I'm sure you realize the anus is a different creature. It's designed to close tight and remain that way - - tightly closed. It has limits. When you exceed those limits it's going to hurt."

"I guess some people like the pain."

"Yes, you're right. - - - Teresa, I'm going to remove this now and insert the plug. It will hurt going in, but once the knob passes through your sphincter you'll be okay."

"But why?"

"The knobs keep it in place. You'll see. The anus will learn to accept it."

When he pulled out the expander it felt even better than the smaller one. Then he relubed my opening and popped in the plug. He was right. It hurt.

"This one has a vibrator, my dear. I'm sure you'll like it. It will relax the muscle so we can continue later. How does it feel?"

"I - I don't know if I can take it. Maybe if you turned it down a little bit."

"Sure. If you like, we can increase the speed again later. Teresa, why don't you see if you can straighten up now. I'm going to take you into the other room so we can have a look at the rest of you."

It took a while for me to stand up properly. The doctor kindly untucked my skirt and let it fall back into it's normal position. At first I felt like I still had to stand with my legs apart, but I found that by experimenting, it was possible to stand and walk normally. The outer "handle" on the plug pressed into my cheeks a little bit, reminding me I should lose some weight.

The doctor beckoned for me to follow him. We exited his office and started down the hall at a pretty fast clip. "Hey, remember me? I have something sticking out!"

"Sorry, Teresa. My mind is on what I'm going to do to you in the examining room. I think you'll enjoy it."

We passed a cleaning lady in the hall. I was sure she could hear the vibrator in my ass, but she never looked up. "This is embarrassing, Doctor."

"Hey, don't worry about it. Just worry about what will happen if you don't tell me the truth."

"But, - - "

"I'm going to enjoy this anyway, my dear, whichever way it turns out."

"You must examine beautiful young women every day. How can you enjoy working on an old lady?"

"Well, let's say I like you. This is a special situation. I have you over a barrel, so to speak.

"What if I don't convince you?"

"Maybe I'll bring Jenny in and let her work on you."

"But Doctor, that's not fair."

"Don't worry. We're going to do this the way I've planned. I don't often have an excuse to put all my skills into practice. As long as you behave and keep my interest up, I think we'll be okay."

We had entered the examining room while we were talking, and the doctor flipped on the lights and removed a cover that was draped over the special table. It wasn't what you'd call modern, but it sported the usual amenities. "Do you think I could have a glass of water, Doctor?

"Of course. Would you like something stronger?"

"Thanks, but I don't think so. I'm tired and I'm driving - - at least I will be if you don't keep me here. Shall I take my skirt off, Doctor?"

"Yes, please."

I hung my skirt up while the doctor drew my glass of water. When he brought it to me I had already stepped up on a little stool and was now sitting on the examining table, my feet dangling over the side. This caused the plug in my butt to press into me a little, but I was able to ease the situation by leaning forward a bit. I finished my water and swung my legs up onto the table. I was pleased to see the knee supports, as I've always found them more comfortable than stirrups I lifted one leg, and then the other, placing them into the forms.
