Sena Ayumu plays a married woman whose father-in-law, Ryohei, lives a lonely life, largely ignored by the family. As the only person who talks to him, Ayumu becomes a frequent visitor to his home. Under the pretense of teaching her fishing—his sole hobby—Ryohei begins molesting her body. Overwhelmed by his persistent, greasy touch laced with the scent of aging, she eventually ends up with his thick cock rammed deep inside her. Unable to confide in her husband, Ayumu suffers in silence—until Ryohei's evil hands reach out to violate her once again.
