A young woman named Lisa is on a crowded bus, holding onto a metal bar above her seat for support as the vehicle sways back and forth. She feels uncomfortable with the close proximity of other passengers and wishes to move to an empty seat. However, the only available spot is directly adjacent to a large, rugged man named Mark. As Lisa squeezes past him to take the seat, her bottom brushes against his bulging crotch area. She tries to ignore the awkward contact but feels increasingly self-conscious about it as the bus continues its journey.
