I moved up near her head where she could watch what I was doing, and then I picked up a latex exam glove and pulled it onto my hand, allowing the cuff to snap in place. I picked up the tube of K-Y and began coating my right hand, covering all my fingers, palm, back of hand, wrist, and part of my arm. Gasping, she asked, “What are you going to do?” My reply was, “I have small hands and I am going to insert it in your vagina, there will be a moment of pain when the knuckles pass the vaginal sphincter, and then an internal pressing against your internal organs when I am completely inside. I will allow my fingers to fold into a fist when penetrating the canal. You will experience something unbelievable.”

I moved down to stand behind her, then checking to make sure the view on the TV wasn’t blocked, I removed the clothespin holding her labia together. She snapped to attention, obviously having forgotten it was there with the other entire goings on. I put the tips of my fingers and thumb together making a wedge and positioned them in front of her slit. With my left hand I spread her lips and grasped the plug I had pushed into her vagina. In one swift movement, I pulled out the plug and jammed my fingers into her wet canal. The plug had done a good job of retaining the secretions of her vagina; I could actually feel the pool of liquid.

The fingers slipped in easily to a point halfway between the first and second knuckle. Additional pressure succeeded in reaching the second knuckle, but then the sphincter was tightening to prevent further penetration. A diversion was necessary. I leaned forward between her spread legs, grasped her left shoulder with my left hand as an anchor to apply pressure with my right hand, then bending down, sucked her left nipple into my mouth and bit down on it. Her cry of pain broke the silence, but the vaginal muscles went slack for a moment. It was enough to force my hand into the knuckles, the maximum diameter needed for penetration. I stopped all movement, allowing the tissue to try to adjust. I knew her orifice had been severely stretched, but there was no damage done. After a couple of minutes her moans quit along with her pleading for me to take it out. She came to the realization that she had no control over my actions and that the exercise would continue no matter what.

Gradually the tension on my hand diminished a little and I knew that would be the extent of it. Very carefully I slowly pushed my hand inside her, folding my fingers as I did so, making a fist when past the sphincter. When the orifice settled around my wrist, I stopped, allowing her to rest. The stretched tissue was now comfortable around that diameter whereas earlier it would have seemed impossible. My fist was coated with her juices, and I sensed that there was little space beyond for thrusting. She had paid the price, now it was time for the reward.

“Are you ready to cum? Have you rested enough?” “I don’t think I can, I am tired.” I was sure that what was about to happen would result in an orgasm, but to make sure I decided a little jump-start wouldn’t hurt. I opened the valve momentarily to force a small amount of the glycerin into her, then waited for the result. Nothing happened right away, I knew she didn’t realize she had been injected. Shortly she gasped and I could feel some ripples of contractions from her bowels. They were minor but sufficient to make her aware of what I did. Now that feelings had been awakened in her, I began my slow twisting. I kept my knuckles on the colon side of the passage so that minimal pressure was on her G-spot, when the moment of orgasm arrived, I would reverse positions and let the knuckles rattle across that tender spot.

She was watching the TV, engrossed in the sight of a wrist twisting inside of her cunt, and starting to moan indicating an approaching orgasm. I picked up the pace a little and with my other hand, reached for the clamp on the hose. Her eyes went wide when she saw that, knowing what was coming. I opened the clamp all the way, allowing the soapy water to force the cramp-producing glycerin into her bowels. I increased the tempo of my twisting while waiting for the results of the injection. I could feel the cramps start deep inside her body.

Suddenly a severe cramp materialized, her eyes were closed as every muscle in her body contracted, then a moan as I felt her vagina pulse with an orgasm. I rotated my hand 180 degrees and rubbed hard against that bundle of nerves with my knuckles. I felt something warm on my arm; I looked down and saw that she was spraying me. Her juices were being forced out of her by her contractions, with my hand and wrist occupying all of her uterine cavity; there was no room for the juices when she clamped down on my fist. It was a short spray and she didn’t see it since her eyes were closed, I waited and watched, shortly another orgasm washed through her with the same result, a short spray from around my wrist to land on my arm. There was no sense in having her look at the TV; she was in another space, the cramps and orgasms totally controlling her mind, shielding her from the outer world. She would enjoy watching the replay on the tape.

The cramps were intensifying, taking over, all sexual arousal overshadowed by the wrenching cramps. When the next one passed and she relaxed for a moment, I unfolded my fist and withdrew my hand. It didn’t appear that she was even aware of what I had done.

I rotated her upright to a sitting position, slowing down the flow, and positioning her for the expulsion. The bag was deflating, but the rate of injection had slowed considerably. She must have been near capacity or totally out of control, because with each cramp, a spray of fluid exited her anus around the tube. I cleaned up my hand, wrist, and arm while the bag finished emptying. When it was empty, she slowly returned to the present, opening her eyes and looked at me. Another convulsion went through her, then she begged me to take out the tube. “Please, I can’t take any more, please take it out.” She didn’t realize that the flow had stopped.

I held her head in my hands while looking at her and said I would, but she would have to retain the fluid. Squatting down, I grabbed hold of the tube and using both hands to maintain constant withdrawal, very slowly pulled on the tube. I could feel her anus unconsciously clamp down on it to prevent the movement, but it was useless. The tube sliding through her sphincter was like a bow being dragged across a violin string, resulting in vibrations. That plus the additional feeling deep inside her of the movement of the tube resulted in a constant moaning. I suspected that she might be having another series of orgasms. Because of the slow withdrawal, it took a long time before the end popped out.

I looked at her, her eyes were shut again in concentration as she tried to hold the fluid, I knew it was impossible. She gave a small cry and I heard her release. The first of many streams shooting out of her was a long one. I began preparing the rinse.

I knew she was weak from the preceding events, so I decided that I would use the Balloon for the rinse. It would be a warm water rinse with salt to replace the electrolytes lost in the previous cleansing s. The Balloon would do the retaining so she could just relax and let it happen. I mixed the solution, filled the bag, attached the nozzle to the hose, and then waited for her to finish expelling. Gradually the bursts of expulsion dwindled to nothing. I removed the restraints from her wrists, shoulders, and ankles, then helped her off the fixture. I helped her down to the floor and placed her in the shoulder knee position with her buttocks raised high in the air. I lubricated the nozzle and bladder of the Balloon, then gently pushed it into her dilated orifice. I gave the bulb connected to the inner bladder four quick pumps inflating it inside her colon. I saw her shudder as she felt it expanding, pushing outward on her anal passage. I gave four quick pumps on the bulb connected to the outer bladder, which expanded and pulled the inner bladder back against her sphincter, squeezing against it to effectively seal it. This resulted in a moan from her.

With her properly prepared, I lay down on the floor and pulled her over me, her legs straddling me and her hips poised above my rigid cock. I eased her down over me and felt my cock slip into the wet hot passage, then pulled her to me. As the two pubic areas touched, I opened the clamp, filling her with the rinse. I could feel her insides filling; at least I thought I could. She was moaning and rocking back and forth on my cock, pressing into my pubic area to stimulate her clit. I could feel the juices escaping from her aroused hole, running down on me. Se would have to clean me; I had other ideas that required a dry cock if I could keep from cumming now. As it turned out, she was somewhat tired but very horny and came quickly just before the bag emptied. I grabbed the bladder sticking out of her and twisted it, rotating the bladder inside her; this resulted in another orgasm. She collapsed on top of me and rested until the urge to evacuate became unbearable. I released the valve on the inner bladder, removed the nozzle, and watched as she ran to the bathroom.

I cleaned up the equipment and waited for her to return, I was rock hard and in need of relief. The first thing I did was make her lick all her juices off of me; I needed to be clean and dry for what was to come next. I made her kneel with her ass in the air and her hands pulling her buttocks apart. I coaxed her to pull hard enough to open her anus. I took the thumb on my left hand, placed it just above her anus, and pulled upwards. This resulted in a small opening in her anus. With my right hand I placed the nozzle on the Balloon and pushed inwards. With and me working by pulling and stretching, we managed to get it inside until half of the bladder was in. The sphincter was around the center of the bladder, half of it in, the other half out. I removed my thumb and concentrated on the task at hand. I pumped the bulb twice and saw the bladder inflate, dilating her anus. This produced a throaty moan from her. I pumped once more and saw that the wrinkles of her rosebud were disappearing from the stretching. Another pump caused pain and the tissue took on a white appearance, devoid of blood. She was pulling harder now to alleviate the pain, of course it was all for naught. I waited, I knew that the body would adjust, the muscle would accept this new dimension, and I meant for it to take even more.

After a while her breathing settled down and her muscle spasms quieted. Very gently I pumped the bulb one more time. The sphincter was stretched even further; the tissue bone white, the rim muscle so thin it looked like it would tear. I waited. She was laboring with the expanding of her orifice, trying to adjust, but the demand was too great. An expulsion of despair wrought the air, and then I knew she was ready.

My cock was rock hard from watching the dilation of her sphincter. I held it in my right hand, and then with my left hand I released the valve. The bladder collapsed quickly and I pulled the nozzle out of her. Her hole remained wide open, but I knew it would collapse soon. I shoved my cock into her. I got almost all the way in before her dry tissue gripped the skin preventing further penetration. I stopped and waited. I felt her sphincter slowly grip my cock like a warm hand would. She was still spreading her buttocks and I could feel her sphincter squeezing now, she had regained feeling and was testing to see if there was any damage, there wasn’t. I remained totally still, wanting her orifice to get as close as possible to its normal size. It took a while, but finally I sensed that the goal had been reached.

I tried to push more of my cock into her, but the dry tissue prevented that, instead the sphincter folded inwards following my cock. The opposite happened when I tried to withdraw; her colon tried to fold back on itself and was squeezed by her sphincter muscle causing pain. This was what I had hoped for. I began dryfucking her hole. I made sure that I didn’t cause enough pain to lower her state of arousal, just enough to enhance it. She was moaning and telling me that it hurt, but at the same time was explaining how she could feel my cockhead rubbing the walls of her colon. I reached around and felt her cunt, it was wet. I wasn’t going to be able to last long; I had been in a state of arousal for too long a time. I stroked her clit as I increased the pace and then I came. My cock was jerking as it unloaded into her, spraying into the canal. I kept stroking her clit until she wailed in orgasm.

I waited until my cock shrunk back to its flaccid state, then carefully pulled it out of her anus. I lay on my back and had her straddle my stomach with her knees. I then spread her buttocks with my hands, and waited. I knew it wouldn’t be long, the cum settling around her sphincter would trigger an involuntary spasm demanding release. I saw her sphincter contract violently, the first of many. As they contractions continued, she began bending forward with each one. Finally she begged to go to the bathroom and expel the substance in her. I said “No, release it on me.” I knew that wouldn’t be easy either, but I waited and soon I saw her anus blossom open and a small stream of cum drip out onto my stomach. She gasped in relief but it took 2 more releases to empty her. I made her lower her head to my legs, then back up until her buttocks were over my face. Her mouth sought my cock, taking it in and sucking the residual cum left in the urethra. I spread her buttocks wide and began licking the area around her anal ring, but not touching it. Now she was pushing out on her sphincter, seeking the attention of my tongue. I teased with my tongue, circling the orifice, touching the wrinkles but avoiding the muscle. There was some spillage of cum that I cleaned up, but the orifice itself was still wet with it. She was clenching her anus and tightening her leg muscles, all the while begging for me to rim her. I let her beg, and then slipped in to lick around that quivering muscle. I slowly circled the contracting muscle, listening to her cum, then felt her juices joining my cum which I cleaned also. I could take it no more; I pushed the tip of my tongue into her anus, which resulted in her cumming again. When she had calmed down, I had her move backwards and lick the cum off my stomach, then we went to bed. I didn’t know it at the time, but she would make a big mistake in the morning. We went to sleep.
