Mizuki, the petite Japanese beauty, takes on a daring challenge: how many times can she make her partner ejaculate within a 3-hour limit? With skilled use of her hands and mouth, she expertly milks his cock, alternating between deep-throating and rapid handjobs. Every time he cums, she swallows eagerly, ready for the next round. His stamina wanes, but Mizuki's enthusiasm never fades, pushing him to his limits in this intense, prolonged porn challenge.
