The good thing was, as a graduating senior he had first choice of all the offered classes. He sat down at his computer and looked over the list. Socio...ogy, Psychology, Inter-cultural-Relations . . . It all sucked! Then he saw it, way at the bottom of the list, the name alone grabbed his interest, “Principles of Lust – An in-depth study of the history and nature of human sexuality” It sounded like pure bullshit, but, hey, he might learn some things about sex and god knew he needed help there. He. He was now more excited than he had been in a long time and he wanted to take over caressing her but he didn't want to waken her from the sexy interlude so instead he grabbed his erect cock and lightly stroked the length as he stood glued to spot.It wasn't too long that her left hand slowly slid under the elastic at the top of her skirt and came to rest on the top of her tiny pink underwear. He moved a few steps to the side so he had a clear view of her hand as she caressed her covered. I watched him stroke himself for a few seconds then reached out with a finger. My finger tip gently brushed against the tip of his cock. When he didn't object I began to gently stroke the head then let my fingers move down to the top of his shaft. A second finger joined it. He let go of his cock allowing my fingers full access.I gently wrapped my fingers round his shaft. He felt so hard, his cock throbbed slightly. My fingers slowly worked their way down his shaft, cupping his balls then. You pumped it with both hands and you felt an insuppressible urge to lick and suck it. You looked back at me and said are you sure. I said, Nothing would make me happier. You turned back around and started sucking as much as you could. It was so thick that you could barely get the head inside your mouth. You were licking the head while it was in your mouth and stroking it faster with both your hands. You felt my cock starting to twitch inside of you, you felt his cock starting to twitch inside.
