After childbirth, the nipples that have become particularly sensitive are targeted by a petty delinquent. On a crowded bus, he pretends to accidentally get close to a woman pushing a stroller and uses the bus's movements to rub or press near her nipples, gradually making her breath ragged. Then, he grinds his crotch against her and exposes his penis, causing the married woman to switch on, and despite her confusion, she complies and enjoys intense sex inside the bus.
