Great scene from a documentary. A guy sees a dominatrix. She spanks him with her bare hands, spanks him with a whip, smacks his cock and balls with a whip and squeezes his balls while he's tied up. All real busts. The file is 60MB.

A hot Korean woman is on a train and a guy stands behind her. He accadentally bumps his crotch into her ass and she turns around, puts her hands on his shoulders and knees him in the balls. He goes down and rolls around on the floor moaning holding himself.

From a documentary, this is an unscripted conversation between a few hookers talking about a guy they service who likes having needles stuck in his dick and balls and some other cbt as well.
