A young couple who boarded a crowded bus. The wife, wearing a tight mini-skirt and with a plump butt, tries to avoid her husband noticing by pressing herself against another man and wriggling, driven by dissatisfaction. The erection is in close contact, increasing excitement. Next to her husband, she grips the other man's erect penis protruding from his pants, excited by the thrill, and slides her panties aside to guide her wet groin, inserting it discreetly to avoid her husband noticing, unable to stop the excitement.
