A horny man boards a packed Santiago bus, his eyes scanning the crowded passengers. He spots an empty seat by the window, strategically placing his bag to conceal his actions. His hand discreetly slips into his pants, grasping his throbbing erection. He strokes slowly, eyes closed, imagining the touch of another. The bus's motion adds friction, heightening his pleasure. He's oblivious to the world outside, lost in his solo performance. The journey ends abruptly, his bag falling as he stands, revealing his glistening, satisfied cock.
