Piston

A Sexual act similar to cave diving. The male not only sticks his head in the woman's vagina, but proceeds to climb entirely inside of her. Once inside of her he sticks his penis out of her vagina. Using his penis the girl goes and engages in intercourse with someone else. (The only downfall to this act is that a cesarean section will need to be performed in order for the guy to come out.)

Piston Puppet

How to describe a person that has been fucked so hard or for so long that their body flops around like puppet with every pounding thrust.

About 3-hours into the surprise gangbang party my wife was a pouncing bouncing spit roasted piston puppet. I warned her about trying to party too hard in the beginning but she's loves looking like a cock pierced voodoo doll within the 1st hour.
