reverse 360 piston jammer

The advanced art of standing in front of someone, inserting your fingers into their anus, then forcefully rotating your wrist 360 degrees, it doesn't matter if it breaks, slowly insert more of your arm into the anus, then another forceful 360 movement, this time on your arm. Once this is completed, a full bottle of gorilla glue is applied to the arm and anus, locking it in place.

John: Hey Peter, why is your arm mangled?

Peter: Because I hit Dave with that reverse 360 piston jammer!

John: Peter, you're dead to me you retarded nigga.

The Screaming Pistons

A sexual act involving your cock, if you’re a dude, or a strap on, if you’re a chick, and a vibrator. You stick the vibrator up your girl's ass and fuck her doggystyle. As your dick (or strap on) goes in-and-out of her snatch, you use your stomach to move the vibrator out-and-into her anus at the same time. The variable motion of your cock (or strap on) and the vibrator going in-and-out of both holes resembles a couple of pistons. Hot to watch, fun to perform and, if done right, you’ll both end up screaming.

Jane cummed five times when Dick gave her The Screaming Pistons.

Those two lesbians are doing The Screaming Pistons.

The Screaming Pistons is like double penetration without the third person.
