The armpits of a wife after taking a bath, the armpits of a wife seen while hanging laundry, the armpits of a wife seen while drinking alcohol, the sweaty armpits of a wife, etc. — seeing his daughter-in-law's armpits makes the father-in-law excited and impulsively assault her. Initially, the assaulted daughter-in-law says 'Please stop,' but ultimately succumbs to the pleasure and allows her father-in-law to have sex with her. Such is the sixth episode of incest between a daughter-in-law and her father-in-law.
