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…”

Seized Piston

Can only be done in cold climates. When you are having sex or masturbating and when you are about to bust you run outside and stick your penis the snow.

PISTON SHUFFLE

Where a woman gives a man oral and the man uses two dildo's on the womans vagina and anus. With all three actions simotaniously it resembles the workings of a motor. Continue until desired affect.

I gave Brooke the piston shuffle and she didn't walk right for a week.

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.

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!
