[KEED-78] Her mother, Yuko Shiraki, who was forced out by her daughter's boyfriend in her absence, went into estrus.

I never thought I'd be attacked by my daughter's boyfriend... She resisted desperately, but there was no way she could resist the young man's strength, and Yuko was forced inside. Even more shocking than being guilty was that he had betrayed his daughter. Yuko decided not to hurt her daughter and decided to keep this incident under wraps. But since that day, her body has been burning hotly since she knew the pleasure of being penetrated by a young meat rod, and she would get wet just by making eye contact with her daughter's boyfriend who had come to play. Yuko oscillated between her mother's affections and the woman's instincts.
