The widow, having removed her mourning clothes, was gently and passionately caressed by her adoptive father, who rubbed her itchy anus and continued to stroke it. (Kawagoe Yui, HEZ-932)

It's the first anniversary of her husband's death. The wound in her heart has yet to heal. One day, her widow, Mio, accidentally injures her hand. Her adoptive father, out of kindness, offers to help take care of her. From feeding and bathing to even caring for her lower body. During this process, the adoptive father develops lust for his beautiful adopted daughter. Faced with Mio's refusal to have sex due to her concept of chastity, Shinya suggests an alternative form of sex to her.
