A salaryman visits a men's esthetician in Tokyo to relieve his daily stress. Although intercourse is not allowed at this particular establishment, one of the female staff members takes matters into her own hands by offering an illicit service that gradually escalates towards forbidden penetrative sex. Her targets are customers with large dicks, whom she teases with dirty talk handjobs, close-up rear handjobs, and even breast smothering using her voluptuous breasts – all while discreetly pushing them closer to the taboo act of creampie!
