Half-sisters Lauren and Kassi are very much amateurs, so much so that they need the firm direction of the cameraman to figure out how to make out with each other or with the clearly more experienced Lindsey and Lindsey. A bit of fumbling is cute; too much of it gets boring.

A little enthusiasm goes a long way, though, and all four girls are happy to give stripping and mutual masturbation the ol' college try. If the camerawork is a little shaky and smiles get a little glazed by the end of the night, at least everyone had a good time getting there.

Retailing: A hot tub full of enthusiastic co-eds.
