Visiting Kentaro’s home for the first time in ages, adult classmate Ito accidentally catches sight of Kentaro’s mother Iroha’s pussy peeking out. Unable to resist the sight of her damp flesh, he pulls out his cock. The sticky sounds wake Iroha, but instead of getting angry, she exposes herself even more and taunts him. Forgetting the taboo between a friend’s mother and her adult son’s classmate, the pair spend the night having forbidden sex that ends with him ejaculating inside her.
