I overheard the girls talking. They seemed to be checking scorecards so to speak. They were rating boys to the enjoyment they got from them.It seemed ...hey both were quite the sluts. Neither were virgins. Thank God my daughter was on the pill. From their talk, both had a very healthy sex life just not a happy one. Sucking dick and handjobs seemed to be at the top of their lists. Both agreed fucking wasn't always the greatest as it never lasted long enough to give them pleasure. I heard them tell. He looked around and noticed that most of the couples had started busily getting undressed as well and Rob was really gratified to see how well some of the eager boy/girl couples were actually helping each other not only get disrobed but also how several of the girls were going ahead and demonstrating for him their jacking off and blowjob techniques in preparation for getting their sex partner's cock hard and prepared to take the condom sheath over his hard erect dick. Rob loved every sex ed. When I said it to him he got really hard in his pants.We walked around to the other side of the wall and he pulled his pants down. His cock was not that big, maybe 5 inches, but I did not care, as I mentioned before I am not hung up on cock size. I dropped to my knees an swallowed him whole and started sucking him into my throat. I do not think he was expecting this because he almost fell over it felt so good. I could tell he was getting close to cumming but I wanted him in my ass. By this. We both heave a bit with the first spurts, so the first to cum sets off the other. Sweet. Sometimes, though, his thrusts are long and deep. He loves to hear me cry out in lust, so one of his best tricks is to pull almost all the way out, flex my rim. He gets two cries: the first is one of loss, a lament of despairing desire, as the cock that I need and worship is almost gone; the second cry is one of ecstasy and rapture, as he flows into me in a smooth invasion of my being. More than once I’ve.
