Horny and discreet, a man boards a bustling city bus, his hand casually wandering down to his crotch. He's not just any passenger; he's a gay exhibitionist, and the bus is his stage. With a subtle glance around, he unzips his pants, revealing his hardening cock. He strokes it nonchalantly, hoping no one notices, yet secretly craving the thrill of being caught. The journey is filled with tension and excitement as he teeters on the edge of discovery, his masturbation becoming more daring with each passing stop.
