The first is Nami, a beautiful, healthy housewife who works at a sports gym. She is a perverted woman who always looks at young men with sexual eyes, and her vagina is always wet. When her handsome nephew happens to come over, she can't resist her carnal desire and invites him to her room, thoroughly enjoying his young body and demanding that he insert it into her vagina. The second is Mika, an aunt with huge H-cup breasts. She is an exercise instructor and her costume is always digging into her vagina, making her horny at work. She can't control her carnal desire and has forbidden sex with her nephew who lives nearby.
