He was lying between her legs. His dhoti was all undone. His naked bums were going up and down as he furiously pumped in between her legs. I stood by ...the door and watched them in amazement, not knowing what they were doing. He was huffing and puffing, she was making weird noises. They were not fighting, that much was clear to me. The action went on for some time and then I took off my school bag and put it down on the ground. The noise made her open her eyes. She immediately lowered her legs. Jiju was pinching My Sister’s erected nipples one by one and she was moaning with pain and satisfaction.Her boobs are 37 D sized (I got from her bra). They licked each other for half an hour and then My Sister cum so My Sister ran absolutely nude towards toilet. Jiju also went behind her. I sad on the bed and kept my eyes on them, the door of toilet were open and both of them standing together in the toilet. My Sister was trying to pee and Jiju was jerking his. My Sister peed all over the. When I offered her relief she started crying and admitted she didn't even know what that meant."Right then I changed the lesson plan for the day. I told her she had to come up and sit on my lap to help me demonstrate female masturbation. I spent the better part of the class calming her down, stroking her hair, and warming her up slowly. Just before the end of class I had her moaning, and her pussy was very wet. When the bell rang she grabbed my hand and pressed it into her pussy. Nobody got up. It seems as though Roomy wanted that asshole often after truly breeding him well the first time. Yes, Bill now wanted to worship his cock and fuck his cock from there on, he was hooked. Time changed and college was now over and Bill and Roomy went their separate ways. He married and had several K--s and has never touched another mans cock since. Those old day emotions started surfacing and that desire for cock has gotten too strong to ignore, especially since he hardly has any sex life these.
