In a clandestine encounter, a gym newbie finds himself in over his head with his buff trainer. The trainer, sensing his eagerness, leads him to the locker room, where he strips him bare, revealing a lithe, untouched body. He starts slow, fingering the newbie's virgin ass, making him squirm and gasp. Then, he pushes his thick cock deep inside, making the newbie wince and moan. The trainer takes his time, stretching and filling him, until the newbie is begging for more. He gets it, in a hot, messy creampie that leaves them both breathless and spent.
