After being fired from her office job, office lady Riri Nakayama begins working at a soapland in search of a new path. She has a stunning figure with a slender waist and voluptuous breasts, though she remains unaware of her own beauty. To satisfy her clients, she offers bondage-based services using ropes. Coated in slick lotion, her soft skin entwines with the ropes, creating an intensely erotic, tight embrace. In this bound state, her intimate service drives men to ultimate pleasure. Riri's seductive pussy nears its limit as her client's excitement peaks—his erect cock thrusts deep into her vagina, escalating into fierce, full intercourse.
