Trevor Tripp is a smooth Asian muscular jock, and the nicest guy. His smile would melt butter and the huge bulge in his gym shorts will harden your cock to steel. As a professional persona trainer he shows you how to work your biceps, his favorite part of the body to work out, and you try not to stare as he shows how big and powerful his guns are.
If you were lucky enough to watch him in the privacy of his home for a post workout jerk off you'd see the big mushroom head at the end of his awesome cock. If he knew you were watching he'd stoke it slowly, getting off on you watching him. He would then flip over and tease his furry hole with his finger as if enticing you to explore further.
He's got a great ass and loves to bottom. But that's for another time, for now he goes back to showing off his hot cock and jerking it until he shoots his load just for you. And if that's not an incentive to work out harder, we don't know what is.
