You know the sound that's made when your stroking your dick and the skin rolls over the top than back down? I swear that's what I heard. I sat there t...ying to figure out if he was really jerking off or if I was imagining it. the only way to find out would be to look, so I rested back against the couch, then used my peripheral the look. sure enough he was slowly stroking his dick. I got really nervous, id never been in this situation before, what should I say or do? I couldn't stop staring. We both stood up, Matt was on her right side and I was on her left side. My mom tilted her head back opening her mouth wide, with her tongue sticking out. She began to massage her tits as she looked at us, "Come on boys! cum all over me!" We both stroked our cocks wildly, looking down at my mom. I had such lustful, dark, deep incestuous thoughts on my mind, I started picturing my mom with my cum all over her. Matt's prick erupted with a huge, long spurt of cum! It splattered across my mom's. There were a couple of younger men I might classify as twinks, and they were hot, though clearly not interested in playing with anyone my age. The crowd was not what I was hoping for, which was basically naked gay sex night at a frat house rec-room.I fooled around with a couple of the more interesting middle-aged guys in the huge playroom, walked around in my towel watching a few other people having sex (watching is one of my favorite things to do), but mostly ended up in the video room jacking. It wasn't as if he had seen a whole lot of bare breasts in his lifetime, but Sandy's had to be the closest to perfection he had ever seen.They were a bit bigger than pears, probably 'B' cup size, but on Sandy's slight frame, anything more would have been too big. From the nipples upward to her chest was a smooth and straight slope. From the nipples downward was a delicious curve with no overhang whatever. Unless her breasts grew considerably larger, it was likely they would never sag.Sandy was.
