My friend Ken and I liked to jack off together, but taught me something more one time. He had done a lot more different things than I, so he suggested that I get on my back and he kneel down over me, masturbating slowly while I stroked his legs, his balls and indeed his feet, which he liked me to do. It was so nice watching his very long erect penis with a big head on it, as he smiled down at me. At one point he said, Roy, I'm going to cum, and did.
The next time he got me to kneel down on him, pulling our erect cocks together, masturbating the both of us, so nice it was, as he gently stroked my legs and my balls and smiled up at me. But then he suggested that I put his cock behind me, which I did, first rubbing it on my buns, then between them, masturbating him as I did that, such a turn on it was that I shot right onto his shoulder.
Finally, another time he wanted to masturbate by me, with his cock close, asking me to stroke it myself then he would stroke it. Finally he came on my chest, which was such a thrill, making me take his still so erect penis in my hand and rubbing it on the cum on my chest. I still remember it.
