The bus rumbles on, filled with the sounds of their lust. The twink, now naked from the waist down, strokes his thick, uncut cock, its head glistening with pre-cum. The older man, his own cock out, jerks off lustfully, his eyes locked on the twink's tight, round ass. They switch positions, the twink now on top, riding the older man's cock in the cramped space, their bodies slapping together, echoing the bus's engine. The scene heats up, the twink's ass milking the older man's cock, until they both explode in intense, sticky climaxes.
