When her husband is suddenly laid off, homemaker Mizuki remodels a room in their house and opens a beauty salon to help support him. Business is going well until a creepy neighbor books an appointment, flashes his throbbing cock, and pressures her to service him. Though reluctant, Mizuki gradually becomes captivated by a size nothing like her husband’s. The insatiable older man toys with her slim-waisted G-cup body, repeatedly cums inside her, and slowly brings the married esthetician under his control.
