In an urban bus, a curious first-timer and a horny regular lock eyes. The seasoned one, eager to corrupt, guides the inexperienced hand to his bulge. The innocent tentatively strokes, then bucks at the sensation of a stranger's mouth on his cock. In the open air, they explore each other's bodies, moaning softly, until the innocent spills his load onto the bus floor, and the experienced one swallows his, marking a taboo initiation under the watchful eyes of the city.
