A bespectacled, married woman with a stunning big bust sneaks away on a secret trip to meet her lover. Heading together to a hot spring, they start making out even before undressing in the bath, delighting in the man's growing arousal. They indulge in foreplay in the water, building intense desire. Back in the traditional Japanese room, the wife takes the lead, moving straight into sex. She grinds her pussy on his face, shuddering with pleasure, then mounts him cowgirl-style, clearly showing their joined bodies. At first, she controls the rhythm, but once the man thrusts back hard, she convulses wildly. Her yukata slips and tangles with every movement, fueling their excitement further, until she melts into a blissful expression as he cums deep inside her.
