A widow whose husband died a year ago, her father-in-law has been lusting after his young wife's body since his son was alive. The father-in-law has been holding back, but after the first anniversary of his son's death, he can no longer bear it and pressures her into having sex. At first the daughter-in-law resists, but Hanazono, who had rejected men, responds and takes her father-in-law's penis all the way to the base. Her brother-in-law notices this and takes advantage of the arousal in the woman's body and starts pounding into her.
