Nao, who is sexless and frustrated, distracts herself by throwing her frustrated thoughts into housework. It is the son-in-law who looks hotly at Nao who is doing housework while sweating. I masturbate while spying on Nao's sweaty bra, but one day Nao finds the scene. On the other hand, Nao can't take her eyes off the young erect penis she happened to see. A meat stick she hadn't tasted in a long time... Before she knew it, Nao was clutching her son-in-law's penis...
