Ruisa, a married woman who couldn't climax with her husband's penis, was diligently doing pelvic floor exercises. However, her overly strict training resulted in her vagina making her husband ejaculate prematurely. This was an irreversible situation. To relieve her sexual desire, she felt guilty about cheating on her husband, but she repeatedly sought out other men in search of a satisfying cock. However, every man she encountered ejaculated immediately. "Oh... could it be that I can no longer expect pleasure from sex...?" Just as she was feeling discouraged, a lone burglar appeared before her, and the story begins with her being attacked by this man! This is a reverse-role, nympho story that starts with rape.
