Four gym babes strap a guy to an inversion table to see what sort of work out his muscles can get out of it. But as they feel how tense his muscles are, they notice that he is getting an erection. They are angry at his lack of control and decide to teach him a lesson. They cut off his boxers with scissors and then take turns to wank and suck his cock. When he cums all over himself, they hold his head so the cum drips down his body onto his own face as they howl with laughter.
