Caio Vilar, the muscled jock, heads to the gym for a workout but finds himself the object of Miguel Trajano's lustful gaze. The personal trainer beckons Caio to a private room, offering an 'aula particular' that's far from academic. Caio, turned on by Miguel's intensity, agrees. The lesson begins with Miguel admiring Caio's physique, tracing his abs and pecs, before guiding Caio's hand to his own throbbing bulge. Caio takes the hint, dropping to his knees to worship Miguel's cock with his mouth, taking it deep until Miguel's precum drips onto his tongue. The lesson turns raw as Miguel bends Caio over, spitting on his hole before sliding in, fucking him hard against the wall, their grunts and moans echoing in the empty gym.
