As I was walking down the hallway to my homeroom I couldnt stop thinking about what Ren had just told me about taking her mothers place when she would...go out of town, my mind kept wandering to nighttime in their house and where Ren would sleep when her mother was not home, I was getting very hard in my pants when I wouldbthink of Ren sleeping in her fathets bed, wondering if she would do things with her father when her mother was gone.I sat down in homeroom with all my thoughts still consumed. He was playing with her tits for a rather long time-pinching the nipples, flopping them in his face, licking the areolas, spitting on the nipples, sucking them in his mouth, even biting them aggressively. Once the nipples were rigid, he brought out a breast pump to further stimulate the aroused breasts. The nipples were extremely hard, almost pointy when she began to leak. Overtly excited, the man abandoned the breast pump and began to suck her breasts ardently. He pulled away from the nipple. This time, her belly and thighs pressed agaist my ass, and my erection started to grow. "Come inside, wash up, and I'll give you something to eat," she said. As we walked to the house, I asked her if she hadn't better get going, and she replied, "I'll have plenty of time now."I washed my hands, and told her I really wasn't hungry. "Thirsty?", she asked. "No, not at all," I replied. She leaned up against the counter and with a sly lok asked, "Horny?" I realized the bulge in my jeans was very. OH! MY! GOD! It was getting even bigger! I tried to hug it but couldn't even reach my arms around it - but I certainly did my best! By this time the knob had risen completely from the foreskin so I stated kissing it. As well as my arms, I wrapped my legs around the shaft & started humping it with all my whorish might - rubbing & grinding my pussy juice all over it. He seemed to be enjoying this very much & was roaring, growling & beating his big muscular chest with his fists. I'm no zoologist,.
