What a massive hunk of man Carlo Masi is. He epitomises the Colt look - big and manly, hairy and rugged, handsome as hell. He takes part in two scenes in Muscle Up!, the opener where he tops Mike Dasher and a scene where he bottoms for Adam Dexter. It's nice to see the hard Masi sit down on Dexter, facing the camera in a solid shot. Some others make lasting impressions, too. Dave Angelo is one hell of a seducer - he really works up Lee Young, picking him up and setting him on the pool ledge, licking his chest, sucking his toes, caressing his torso and neck, sniffing his swimsuit. Viewers might shoot a load before the action begins. Chris Wide also shows off his nice meat in a jack off only scene with Roger Danik, but it's Pierro Sias' rigid erection that is the sweetest sight in the whole feature. Cast: Dave Angelo, Edu Boxer, Mike Dasher, Adam Dexter, Carlo Masi, Chris Wide, Roger Danik (Nick Lord), Pierro Sias, Lee Young
