A packed bus, a hot day, and a bulging crotch start a chain reaction of lust. On board, a rugged gay man notices the prominent package of the passenger beside him. Unable to resist, he discreetly reaches over, giving it a gentle squeeze. The recipient, surprised but aroused, reciprocates, his own bulge growing. Their secret game of touch and feel intensifies, beads of sweat mixing with their pre-cum as they struggle to keep their composure amidst the unaware passengers.
