Reverse Booty Twist
A difficult defensive maneuver executed by the “bottom” participant during anal sex in which said individual backs up on the dick in their ass and performs a 360° degree corkscrew turn that forcefully ejects the penis from the anus.
I was hitting her hard from the back but I guess she had somewhere to be cause she hit me with that reverse booty twist and sent me back on my ass while she rushed outta the room.
