She watched as I combined the ingredients; however she failed to notice the actual amount of each ingredient I had put in the solution. It was a small amount yet sufficient to produce the desired cramps. The mere sight of the bottles was enough to instill fear in her mind. I filled the larger bag and attached the large tube to the hose. A quick purging of air brought the familiar gurgle from the tip. The tube was dry except for a drip from the hole in the end. I know she was wondering how such a large tube could invade her without lubricant, but I knew it wouldn’t be a problem since her lower colon was packed with the K-Y. The Vicks would ease it past the sphincter, and then the tube would be coated as it penetrated deeper inside her.

I sat behind her with the tube and waited. Her body was rebelling from the filling with the K-Y, the natural reaction trying to expel it, but her sphincter clinched tight to prevent that. I waited knowing that sooner or later the sphincter would give way and the grease would be pushed out. I placed the end of the tube on her anus in preparation of that moment. Sure enough, the feeling of the cold tube on her wrinkled opening caused her to lose control. A loud moan escaped her mouth and her anus blossomed outward to expel the intruding substance. Just as her orifice opened and the first of the lubricant squeezed out, I pushed 4 inches of the tube into her. Her reflex action caused her anus to clamp down on the tube, but it was too late, entrance had been gained and there was no stopping the invasion. I slowly pushed the tube into her in increments of a couple of inches at a time. I didn’t wait for her to adjust to the penetration; I just kept pushing the tube in, forcing it around the turns of her bowel, going deeper and deeper inside her. With the amount of lubricant just inside her sphincter, there was no way she could stop or even hinder the penetration. Her orifice was still occasionally dilating to rid itself of the mass of grease demanding to be expelled, but the only result was to coat the tube outside her anus thus aiding it’s penetration. The insertion went without a hitch, burying the entire tube in her bowels. I packed some tissue around the tube where it disappeared in her orifice, then removed the tape holding her cheeks apart, pulled her cheeks together trapping the tube, then taped them together to secure the tube and minimize any leakage.

Without any warning, I opened the clamp. She was still adjusting to the insertion when the fluid started filling her deep within her tract. She remained motionless for a few seconds, unaware of what was happening, then felt the fluid surging through her. The first moments of filling were erotic; causing her to moan in response, as she filled the ecstasy was replaced with a full feeling, then an uncomfortable full feeling, and then a feeling that she could take no more. Words softly flowed out of her mouth claiming that she was at capacity, I ignored them. I noticed her anal sphincter contracting against the tube in rebellion of the filling. The flow had slowed considerably, but the bag was still deflating indicating her bowels were still receiving the fluid. Finally it came to a stop, she was full, and I waited. I didn’t have to wait long; a gasp ushered forth from her open mouth as the first of the cramps seized her. Her vaginal muscles contracted along with her anal sphincter and inner thigh muscles. After a series of three cramps, they subsided and she rested. I slowly pulled six inches of the tube out of her allowing the bag to drain some more thus filling the void left by the tube. Just as the flow stopped, another series of cramps coursed through her. This whole process was repeated until only the tip of the tube was in her and there was no room for any more fluid. She was in agony now, the cramps intensifying with the additional filling.

I coated the expandable plug with some Vaseline, then quickly removed the tube and pushed the plug into her. Some fluid leaked out during the process and ran down her legs. Holding the plug in place, I pumped the bulb until it expanded to the maximum, spreading her bowel and gaining in size until it couldn’t pass her sphincter. Since she was sufficiently sealed, I cleaned up the spillage and removed the restraints allowing her to stand away from the fixture. Because of the severe discomfort, she was crouching rather than standing. The filling of her bowel applied pressure to her filled bladder causing a separate pain that she begged to be free of. I said we would alleviate that condition shortly; I had a use for her water filled bladder.

Placing my hand under her chin, I pulled her face up until she looked at me, then explained that now we would begin the foreplay that I was cheated out of. It would be enjoyable for me, but not for her. I wanted her to bring me to a climax but very slowly, and at my instructions, she was to do as I said and take no initiative on her own. She had started to reach for my cock and stopped midway on hearing those words. A subtle yes spilled from her lips and another cramp took control of her. Now the fun would begin, she would dread the action that controlled her desire earlier.

I decided that I wanted some prostate attention, and needed to clean out my lower bowel first. That would require an enema, but I had a special one in mind. I clamped the catheter and removed the plug, then coated the end with lubricant. I knelt down on the floor on my knees and chest, and then told her to kneel behind me as if she was fucking me. I felt her snuggle up against my buttocks, then lay down on my back, her nipples pressing into me and her hands reaching down to grab my cock. I reached back between my legs and found the catheter, then eased it into my anus. When it was in I released the clamp. I could feel her shudder of relief as the pressure in her bladder diminished, then the gentle filling of me as the water left her and entered me. It was almost unnoticeable since the temperature was exactly the same as my bowel.

Either her cramps were quiet for the moment, or overshadowed by the release of her bladder. I could feel her nipples harden and then she began a rhythmic pumping against my buttocks while filling me. One of her hands was stroking my cock while the other was fondling my balls. She was kissing the back of my neck and trying to bring me to a climax. It felt good but I had other plans that would delay that event. I removed her hands, which then went to play with my nipples while at the same time her nipples were rubbing against my back. I felt the flow stop indicating that her bladder was empty. I removed the tube and motioned her away from me. To prevent any further draining, I pushed the plug into the end of the catheter.

I pulled her against me, her swollen belly pressing against mine, and her back arched to push against my cock with her crotch. Any movement brought the tube and bulb brushing against my legs. I reached behind her and felt the crack of her ass where the inflating tube for the plug entered her. I made short jerks on it to trigger the cramps again. It worked; she collapsed against me as a wave of cramps coursed through her. She started rubbing against my cock, thinking that as soon as I climaxed, she would be allowed to expel. I let her rub but my mind was centered on the beginnings of my own cramps. They were short stabs of discomfort now, but I knew they would increase in intensity shortly. Of course they would never grow to the magnitude that she was experiencing, and of course I would get relief any time I desired. As the cramps went through me, I supported her buttocks and pushed on the plug in her anus triggering more cramps. We held on to each other as the severity increased.

When I felt like I had had enough, I led her into the bathroom where I sat on the toilet and had her stand in front of me. I had her spread her pussy lips so I could inspect her inner sex. The catheter exiting her urethra had pushed the flesh away, which strained her clitoris. Her vagina was wet with moisture but not secreting in the throes of passion. Her cheeks were spread from the internal stretching of her bowel, the tube and bulb looking small in comparison. In the sitting position on the toilet the urge to evacuate was greater, but I managed to contain it.

I slipped two fingers into her moist cunt, pushed upwards to where the G-spot was, and could feel the catheter just on the other side. Pressing so that a finger was on either side of the plastic tube, I began rubbing the magical spot. She moaned and bent over to rest her arms on my shoulders. With the pressure relieved on her bladder and the adjustment to the ever-present cramps, she began to become aroused. I increased my stroking, pulled a nipple into my mouth, and commenced biting down on it hard enough to produce an erotic pain. Her cunt was squeezing my fingers hard now, building up to an orgasm.

I ripped my fingers from her cunt and taking a nipple in each hand, squeezed and twisted it violently to bring her down from the pinnacle before she came. “There, foreplay, that is the lesson here, we have all day to reach a climax. I am going to empty myself now, you know how intense that can be, to release the injection and alleviate the cramps.” She whimpered at the thought, then when she quieted down, I let loose of my sphincter. The sound of the water exploding from my bowel intensified the need for her to seek relief. I pulled her toward me and hugged her as I emptied which took several minutes. The sound of me getting relief amplified the cramps in her bowels seeking the same release. She was hugging me now and murmuring softly “Please.” I ignored her.

When I had finished and cleaned up, we went back to the bedroom where I climbed on the bed and knelt down on my knees and chest with my legs spread. I had her coat her index and middle finger with Vaseline, then push them into me. With a little direction, she found my prostate gland and I had her gently stroke it. Several times she tried to increase the pressure or the rhythm which I prevented explaining that it was foreplay that we were interested in. I also made her keep her other hand off of my cock, which was a natural thing to do. As I became aroused, I let her take a finger and spread the pre-cum fluid over the head of my cock, making it shiny and slippery. Just before I came, I had her remove her fingers, and then I rolled over and made her put her head close to my hard cock, but not to touch it. She was staring at it, watching it twitch in excitement, her tongue periodically sticking out in a desire to lick it. “Remember, foreplay is the key.”

I was in bad need of releasing my built up load of cum, but wanted to make it unique. I came up with an idea. I slit the sheath releasing the retention bubble on the catheter so it could be removed, but left it in place. I draped a robe around each of us and led her into the back yard. The neighbor watched us but lost sight of us as we walked behind the bushes. Once there I removed our robes and spread them on the ground for us to lie on. She was looking around to see if we were being watched, nervous at being naked outside in the daylight, but knowing that relief was coming soon, evidenced by my throbbing cock. Once I came, she knew she would be allowed to expel. She dropped to her knees and took me in her mouth, working frantically to speed up my orgasm. I pulled her off my cock. She moaned in disappointment.

I lay down on the robes on my back and motioned her to squat over me. She was on her hands and knees straddling me. I reached between her legs and laid the catheter over my left hip where it would be accessible, then reaching behind her to hold the inflation bulb out of the way; I had her settle down on my cock. As my cock penetrated her pussy, she collapsed on my chest. I could feel another cramp take hold of her, probably caused by my cock taking needed space inside her. I pushed on the retention plug to acknowledge the cramp, and without her knowing it, opened the valve a small amount so the plug would slowly deflate.

I pulled a nipple into my mouth and began a steady pumping into her pussy. She was wet from involuntary reactions but was anticipating the end and wishing it over soon, oblivious to any pleasure from the coupling. As I thrust I could feel her bowels recoil from the cramps, aiding in the stroking of my cock. I bit harder on the nipple as I felt the contractions beginning in my groin signaling the approaching orgasm. I was close, I held off wanting the timing to be perfect. To hasten along the event, I slowly pulled the catheter out of her. She cried out as she felt it exiting her, I also could feel it rubbing along the length of my cock as it retreated. I rammed deep into her and shot my load of cum. At the same time the plug had reduced in size and no longer was prevented from sliding by her sphincter. When the hot cum hit the back of her

cunt, the plug and a stream of fluid exploded from her anus. She curled from the reaction. Another contraction deep within her caused another expulsion. I could feel the violent wave of fluid against my cock as it rushed out of her. This triggered another spurt of cum from my throbbing cock. She finally noticed that I was cumming and began stroking in time to the explosions from her anus. We lay coupled until all of the fluid was pushed out of her. I am sure the neighbor heard us and thought she knew what had happened, but little did she know.
