Noriko Yada is at an age where her children are already independent and she even has grandchildren. Yet, her youthful beauty shines unbelievably bright, radiating a vibrant, erotic charm. Her relationship with her husband is merely coexistence, with almost no sex. Currently, she's been having affairs with two secret lovers, both of which she's finally trying to end. However, she hasn't been able to completely cut ties, and a selfish desire has begun to grow—she now wants to have sex with even younger girls. To satisfy these feelings, when her ample breasts spilling out from her beige lingerie are caressed, she gradually slips into a lustful state. Overwhelmed by pleasure, she can't hold back any longer and lets him cum inside her.
