Math and science were strongly pushed by our educational system. There was a class on sex that we had to take each year. We were taught the few rules ...imiting our activities and given the opportunity to try many different positions. My only time being butt fucked was in that class. Even though the teacher, Mister Clark, was gentle, it wasn’t for me. I even lost my erection! I wasn’t the only guy who found that he didn’t get off that way. Interestingly, a few of the girls didn’t care for anal. After 5 or 6 very heavy thuds, he pushed it back in my mouth, grabbing me by the back of my head. My only option was to just open my mouth as wide as possible and relax my jaw. He started thrusting, and we settled into a nice rhythm, although I'm sure he wanted to thrust deeper. A few times I felt the head tickle against the back of my throat but never more than once or twice in a row. I fondled his heavy balls with my left hand and slowly worked my own cock with my right hand. He was. I felt still like a child doing whatever dad asked to do me. He helped me unbutton it and then removed it. I was wearing a soft cotton bra inside. In fact I never needed a bra but I did wear as an extra accessory to cover my small breasts and dot-like nipples over them.“Remove the bra also, Sumathi…only then you’ll feel comfortable” He was asking me remove even the skimpy bra that I was wearing inside. It was the last piece of dress on my body. He himself unclasped the bra, from the back,. Her cry`s, of “Oh, yes” and “yes, yes, yes!” music in his ears till with a gasp he filled her, she herself her hips rising pushing them both away from the rug, joined him in a groaning climax, then collapsing as he eased himself to a standstill, a spent force. They lay together, silently coming down, till he raised himself to his knees, caught sight of her swollen and wet red sex and could not resist, bending to kissing, the cum filled opening, immediately she began to protest and sit up to.
