In the sultry streets of Rio, a young Brazilian twink discovers the erotic allure of his bicycle's pedals. Barefoot and reckless, he grinds his feet against the rough surfaces, feeling the friction against his soles. His cock twitches and stiffens, tenting his shorts. He leans forward, thighs clenching, hips bucking as he rides, the rhythm of the pedals echoing the motion of fucking. The city's heat and his exertion combine, leaving him sweaty and breathless, his hard-on aching for release.
