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.
