"Correct!" I assured her. "One last hint: when the boy starts to shake and his cock begins throbbing and spasming, concentrate on swallowing as much...of his cum right down your throat…he'll love that!" She smiled broadly as the wheels in her brain processed all the new information I gave to her.By now my own cock was already screaming, and I didn't expect to last very long. "Let's try it!" she announced, as I pulled her head closer to my member which literally shivered in anticipation."First,. . where to begin, masturbating is like sex, except you do it on your own, here do what I say, first spread your legs." So following her instructions I spread them."Now I'm going to show you how to do this once, but for future reference, you do the same thing, but you use your own hand." As she said this, she reached out, took my hard cock in her hand and began to pull it up and down my cock, slowly at first, but picking up speed with every stroke. She then put one of her fingers into her mouth. I helped him off his pants, and he was working on my blouse and off it went.I was going mad, and he started taking charge (surprising for a virgin), but he got on top of me in the bed. He started kneading my tits, and really squeezing them. He started sucking them, and on my insistence was biting off my nipples…I was on cloud nine, with my juices really getting stirred up.He had no problems getting inside me, He could reach my depths with constant pounding, and I was enjoying some real good sex. Of course a side benefit is that I can see everyone entering and leaving without having to interrupt anything. So I watched her come in and make her way down to the front row, taking her seat with a wide smile back at me.God, she was heart-stoppingly beautiful! A small black girl; actually she has a sort of warm honey-colored skin that just makes you want to lick her. So help me God, that vision of licking her all over just flooded my mind, and I had to look down at my notes for quite a while.
