A masochist wife who is good at being scolded

A father-in-law and a brother-in-law spend sleepless nights, troubled every night by the loud voices of Rio, his sexually active wife who never misses a night's activities. Not only that, but I make some sort of mistake every day, so I have no time to relax. One day, while her husband is away on a business trip and she hasn't had sex in a long time, Norio is masturbating to release her sexual desire. As punishment, she is ordered to clean in a naked apron, but her horny stepfather plays with her big breasts as a "punishment."
