My stepmother, Chisato, is 48 years old. Since losing her husband three years ago, she has lived as a widow, but she seems visibly troubled, unsure of how to deal with her own sensual body. Though she dedicates herself to taking care of our household, lately my needs have gone unmet because my wife is pregnant. Perhaps because of this, I've started consciously seeing my stepmother—whose age isn't so far from mine—as a sexual object. One day, I caught her masturbating in the bathroom, and my heart was deeply shaken.
