During a family trip to the hot springs, an amateur female college student made a bold proposition to a man: 'Could you wash my penis with just a towel in the men's bath?' She was challenged to an intense cleaning mission, aiming to win a high prize by pleasuring the male guests' erections in the bath. The sudden appearance of a large-breasted female college student in just a towel left the male guests unable to hide their surprise and arousal. Despite her shyness, she serviced multiple fully erect penises, sucking and pulling out semen repeatedly. Her own arousal grew, leading to messy, frantic sex covered in semen.
