Scissor Piston

Similar to female on female scissoring, a Scissor Piston is the sexual act of two MALES scissoring. During the sexual act, each male interlocks taints and has his penis inserted into the other’s rectum while making a pumping piston action.

I walked in on a couple dudes doing a little Scissor Piston in the bathroom at the rave Friday night. They were squeezing each other’s nut sacks like turkey basters as they pumped away!
