Bedroom MF, mast, plaster Bedroom It started out as a lark. Tim, my boyfriend, was hanging around in my workroom while I was trying to finish up some sculpture that had been ordered. Specifically, I was making stoneware copies of an original that I had made several months ago, so it wasn't as if I was doing anything really creative. Tim would tease me a little just to keep me interested in him, then he would go off around the room looking and asking all sorts of questions. At one point he came back to me saying that he was surprised that none of the men I had sculpted were built anything like him and, to make sure I didn't misunderstand him, he cupped the bulge in the front of his pants. Now, mind you, Tim isn't one to brag but he certainly would have reason to if he wanted. His cock is a good 9 inches long and 2 inches in diameter most of the way. The first time we made love I was sore for two days afterward and not because I had been a virgin. Or maybe I was in the sense that I had never before been fucked by such a prodigious weapon. I wouldn't have even let him near me if I hadn't been so horny that time. But back to my story. When Tim teased me about not using his cock as a model for any of my sculpture, I got this crazy idea of using his tool directly for duplication just like I do with my original sculpture. I told him about my idea and he was certainly less than enthusiastic to be sure. But then I teased him a little about being afraid to let anyone see his "secret weapon". That was almost enough to convince him he should let me make a mold of his dick. When I told him how simple and harmless it would be he finally agreed. I instructed Tim to completely disrobe before we proceeded because we didn't want to ruin his clothes. I took off my clothes, too, more because I wanted to be naked with him than because of any danger to my clothes. While I mixed the special powder with ice cold water, Tim ran his cock up and down my ass making me have second thoughts about what we were about to do. I really wanted to fuck. But it would be a waste of good material to stop now so I started slopping the stuff onto his stiff cock. As the icy material hit, Tim reacted first with a few choice words about my trying to kill him, then with his cock dropping several degrees in elevation. Now, one thing I didn't need at this point was an impression of his limp cock so I handed him the gloppy mixture and told him to continue to spread it on while I knelt behind him and began tonguing his asshole. I don't particularly like doing it but it is guaranteed to turn him on no matter what. Sure enough, within seconds his rod was as stiff as before. I continued my tonguing until the material set. This stuff sets up within 2 or 3 minutes. I could tell the time had come because Tim complained about not being able to put any more on his cock. At that point I reached around to test its firmness. It was ready. I tugged it sharply which caused Tim to yelp in pain. I had pulled out about 15 pubic hairs but even more the suction developed from this mold of his cock sucked his prick more than he'd ever been sucked. As I continued to pull it off, he complained that I was going to suck his balls right through his cock. With that I gave his balls a sharp pinch causing him to go partially limp and freeing up the mold. Tim helped me mix up the quick-setting plaster that we would use for the first model. It is pink because it is used by dental technicians to model gums for false teeth. We figured that would add to the realism. Within a minute after we had poured the liquid mixture into the mold it had set hard. I peeled the mold off hoping it would be able to be used several times. The likeness was astounding. Although it was cold plaster I got hot just peeling it. Tim was even more fascinated with it than I was. After all, I had see his cock close up but he's always been 18 inches or so away. As he examined and felt this stone imitation of himself, his cock became almost as stiff as the plaster model. He self-consciously tried to open his mouth wide enough to encompass the model and realized it would be impossible. It also dawned on him just how such a tool would feel sliding up his ass like he's slid his into mine. That day I didn't give him a chance to worry about anything since by that time I was ready to be fucked. But it did give me some ideas for future projects. In fact my next project was a model made of a stiff rubbery substance with the firmness of tire rubber. It will bend slightly but not easily. It was also black as a tire although the finished product was smooth and almost glossy in places. The material takes up heat so that it feels much more comfortable to the touch than the plaster model I had made before. I had molded a six inch handle on the base of it so that it would be easier to work with during construction but it turned out it was too good to cut off afterward also. While putting the finishing touches on it I got so hot my pants were literally showing the dampness through both layers of cloth. The shape and size were Tim's but the color made it look like the cock of a black man. I decided to call it The Black. As I said, just working with it was getting me horny so right there in my workshop I shamelessly dropped my pants and proceeded to insert my new toy between my legs. My mind told me that it was exactly the same size as Tim but the blackness brought to my imagination the vision of a tall black dude fucking me. By the time I had the entire shaft inside, I was literally whimpering with pleasure. The next day Tim came over and I got this awful idea in my head. As usual, Tim's thoughts were on sex and within an hour of his arrival we were naked in my bed. Telling Tim I wanted to try something new, I spread hand lotion all over my hands and began to massage his cock and balls. He was delighted at the sensation and didn't fuss at all when I slipped a finger down along the crack of his ass. In fact, he was so preoccupied with what I was doing to him that he readily turned over on his knees when I asked him to. Pretty soon, I had one hand pumping a very slippery cock and the other prying open his anus. By first slipping one then two fingers into his ass I knew I was heightening the sensations he was getting on his cock. When I felt he had reached the proper degree of relaxation, I quietly placed The Black against his hole and pushed with all my might. It slid easily until it was half buried in Tim's ass hole but there it stopped. But Tim let out a yell that could have wakened the dead. Leaving The Black for a moment, I grabbed Tim's balls and told him that I would rip them out if he let out another cry like that. I squeezed just enough that he knew I meant business. However, he began moving his bowels in an effort to dislodge the black menace. That simply gave me the opportunity to slide it all the way in. Tim moaned and begged me to please remove the giant cock. To see my macho boyfriend completely at my mercy gave me such a thrill. But I didn't want to kill him so I yanked The Black out...almost. Having been fucked in my ass, I knew that he would then beg for it back to fill the void and reduce the vacuum I'd just caused. He did, while gasping for breath as if I had slugged his stomach. This time I pushed it in slowwwwwly then began a series of slow ins and outs. Tim's cock, which had shriveled when I had first inserted The Black, was now as stiff as ever and I was getting so turned on, I wanted it inside me. I crawled down between his legs and pushing myself under him managed to bring him back down inside my throbbing love pot. He held my feet tenderly while his balls were crushing against my swollen clit, The Black was sliding in and out of his bum, and he was sobbing. I moved the angle of the dildo to what I knew would massage his prostate better and immediately got a yelp of surprise and pain from Tim. That was followed by spasmodic jerks that I have come to recognize as impending ejaculation. I wasn't very far behind. As Tim started to come, I pulled The Black out all the way, then pushed it back in all the way. Again and again I fucked Tim's ass furiously as he fucked me and his come seemed to last forever. God, what a feeling! The next model we made with the mold was of flesh colored latex. This time we included a tube from the base to the tip so that liquid could be pumped deep inside whatever the cock was penetrating. Then we molded a couple of balls free hand and attached them loosely to the prick. Inside the balls were rubber balls which we glued to a Y connection and that to the cock tube. When we were done the result looked even more like Tim's cock except that squeezing these balls dumped their load. The Y even had a special connection that prevented liquid from coming back in unless pressed in just the right way. Now it was my turn to be exploited. Tim gently worked The Black into my ass until I was more or less relaxed. Then he substituted the Squirt, as we called him, having filled the artificial balls with what he told me would be a "soothing" solution. He then washed The Black and inserted it into my vagina. I felt full but not uncomfortable. Tim positioned me on hands and knees in front of him so that I could suck his cock while he played with the toys sticking in my bottom holes. As I gulped on Tim's throbbing cock, Tim pulled and pushed, in a more or less random fashion, the two artificial rods that were fucking me. I was definitely getting into the action as my pussy was getting wetter and I was losing touch with reality. I felt liquid squirt up into my intestines. It jerked and spurted like Tim's sperm would have and I had a mini-climax right then. This was going to be fun, I thought. After a minute or so of enjoying the friction of the three cocks, I suddenly realized that I needed to shit, badly needed to shit. I tried to remove Tim's cock from my mouth to alert him to my problem but he was too far gone to let me. Tears were welling up in my eyes as I struggled to hold in the rising tide. I saw then that Tim knew what my problem was and my distress was actually leading him to a climax. I couldn't free myself and soon, in addition to the cramps that were racking my bowels, I felt Tim's hot sticky cum hit the back of my palette. I gagged. I felt like I was suffocating now. But still he continued. Finally, his hardness left and I pulled away and ran to the toilet. Yanking out the Squirt, I opened my bowels and pushed. What seemed like a gallon of putrid liquid rushed out, giving me an instant high. I even began pissing before I realized that The Black was still in my front portal partially blocking my pee hole. While I sat there catching my breath, I noticed the empty Fleet Enema bottle on the edge of the sink. No wonder I had had such an uncontrollable urge. I wanted to be furious at Tim but when I thought of how I had violated his backside, I decided that we were now about even.
