Our Models Behaving Badly video series was a big hit on our Sharp Men website, so we collected the best and put them together in Muscle Explosion Vol. Eight. Watch 7 professional models being unprofessional. When the official cameras are off and they are in their dressing rooms, these muscle and fitness models whip out their private cameras and film each other doing things they wouldn't dare do in front of their print and TV gigs. With a trusted buddy behind the cam, these well-known stars get naked and put on a private show you wont see anywhere else. These studs get so turned on showing off and touching their own hard bodies, they don't stop until they get themselves off. And a couple of them even feel and fondle their naked buddies as they film them. This certainly isn't typical model behavior.
