Bondage widow Komatsu Chiharu

Yumiko loses her long-loving husband in an unexpected accident, causing her to feel lonely. Shinji, her husband's younger brother, gently approaches Yumiko with such kind behavior, but gradually she exposes her own sexual instincts and tries to force Yumiko's body into her own body. Shinji seeds are planted inside Yumiko's vagina, after being tied up, shamed and trained in front of the memorial photo of her late husband.
