We got to Marvin apt, he was on ground floor so I could park almost at patio door, got out and walked up side walk door slid open and Marvin was there...nothing on but a hardon, when we walked in saw 5 other bulk guys all naked and hard, Marvin told me to get her dress off, they gonna fuck her first get her heated up for me to fuck her up her ass. Marvin gave her a glass filled with rum and coke,pulled her nipples while she drank it then pushed her to her knees told suck his dick then started. I got up as close as I could, pulled down my trunks and started to jack-off. I tried to not make any noise and really don't know if I did or not, but, then she seemed to spot me up on the dune and pointed me out and they were soon laughing.Me, I was cumming. The couple probably knew what I had done, I really didn't care. I was feeling too good enjoying the sexual release after seeing such a sexy sight. I think the woman kept looking up at me, it was hard to tell for sure, she had on sunglasses. The thong that Jim was wearing right now, the one he shot the big load of cum into that was slowly drying on his rehardened little dick. The next picture appeared, mummy and Tina were hugging each other. Then a modest kiss on Tinas cheek, followed by a picture showing the two of them sharing a passionate kiss. Jim coulnt beleive that mummy was kissing Tina. He knew that they were best friends but he could have never imageind that they would be lovers too. Some more pictures of them kissing and. I walked my knees back a little so I could lean further into him with my jaw forward, straightening my neck, all the while bobbing on his cock relentlessly. I heard him moan, his hand went to my hair, and I knew he would soon no longer be able to resist pumping his hips. I wanted him to thrust. I put my hand around the back of his thigh, so taught, almost as hard as his cock, and pulled. The tip of his cock broke the barrier of my throat and plunged past. He thrust reflexively. Both of his.
