A lanky teen boy with a massive cock steps onto a bustling bus, his eyes darting around nervously. He finds a secluded spot by the window and, with a subtle glance to ensure no prying eyes, begins to stroke his enormous dick through his shorts. The fabric tents as his thickness grows, drawing curious stares from fellow passengers. He ignores them, lost in his own world, as he pulls out his throbbing meat and starts beating it in earnest. His grip tightens, rhythm quickening, until he's on the cusp. Suddenly, the bus lurches to a halt, and he's left hanging, pants around his ankles, as a group of students board, their eyes widening at the sight of his engorged cock.
