A father-in-law who fell in love with his son's wife, Kasumi, who should never be interested. Kasumi's gentle smile is wonderful, and her body is erotic no matter what.

A wife who masturbates to show off, a wife who gently gives a blowjob in the bath, and his father-in-law's delusions are expanding.
