Todd was doing something like this to Alice and Amber during Surprise Anal Sex Week at the Kinky College:

She saw a large man who had stacked two short, skinny, bleach blondes - who looked like they must have just turned eighteen - one on top of the other over the arm of a couch and was furiously pounding into their once tight assholes in turn. He’d pull his eight inch cock out of the one on the bottom and then plunge it full force into the one on top only to yank back and pierce the first one again. They squirmed and cried out each time he thrust into their battered assholes.
