I didn't care of course, but I felt awesome knowing Tanya and mom had gotten comfortable with this kind of conversations around me, forgetting I was a...teen. I felt like one of the big girls. Mom,"He is fun to suck on though, makes for an interesting deepthroat."Tanya, "You are such a whore."We all laughed. If it weren't for the videos I was watching, I would have been clueless, but no one seemed to notice I knew more than I should.I kept getting more and more attention at school. I was growing. I almost wanted to give him back his check and call the whole thing off, but I discovered something about myself as I stood there quivering as I removed my blouse, skirt, shoes, and socks. I was turned on. I had juices running down the inside of my legs and I could smell my own excitement. I don't know what excited me more. The taboo of having sex with someone old enough to be my grandpa, or not knowing what he might ask me to do, or the fact that this was all new to me. Well, I knew what sex. Throbbing, pumping, pulsating around my rock-hard erection. Eyes closed, it felt like I had been taking this feeling for forever, and I knew I couldn’t last for much longer.“M-m!” mom disagreed when a powerful spurt of thick goo suddenly shot into her mouth. “M-m-mm-m!” complained my mother, who was on her knees. Her lips had been the warmth I had been feeling, although I had closed my eyes and tried to think about pretty Jenny Fisher rather than my mom. Constantly feeling my mother’s breasts. My Girl Friend’s skirt had gone up and he could see her sexy thighs. He knelt and told me to go to the corner of the bed. He sat in front of her and started touching and rubbing her legs. My GF had long slim tan legs like a supermodel and silky skin. John was savoring every touch of her. He would move his hands up and down slowly while looking at my GF to see her reaction. They both were enjoying each other while I sat on the corner watching them. I was getting turned on watching that fat old.
