Stinky Piston

Take someone who is face down ass up and lube up your arm and repeatedly punch them in the asshole until your whole fist and arm enter. After it is in, then proceed to pump your clenched fist in and out. Making your arm bend and extend having the look of how a piston works. Hence… The Stinky Piston.

If you don’t shut up, I’m gonna give you a Stinky Piston!

triple piston

When a man, nude, between two females, as he is fingering both of them, one of them has a hand on his balls and the other is jerking his penis vigorously until they all get off.

Looks like a triple piston kind of night.

Pittsburgh Piston

A term used to describe when someone is getting their dick sucked or rode by a person while they’re driving a vehicle.

“Hey, do you mind if I give you a blowjob while driving?” she said. “Oh, you mean a Pittsburgh Piston?” I responded.

“Dude, get this. She rode my dick WHILE I was driving! Ain’t that crazy?”
“Damn! That Pittsburgh Piston must’ve felt nice…”
