Zack’s girlfriend has been visiting her mother, so he hasn’t gotten any for a while. He picks out a porn video, gets totally naked and begins stroking his huge dick, as I watch off camera. Zack doesn’t know it yet but I have a surprise for him. Zack turns around and sees the jelly masturbator sleeve that I’m lubing up, so he nods me over. When I start stroking him with the slippery sleeve, I can tell he’s enjoying it, because his cock is so stiff in my fist. I jerk him hard and fast, until he spurts out a massive load of cum all over my hand.
