Close friends Sayuri and Non are chatting about their sex lives when Sayuri reveals that, while her busy husband is away, she has been enjoying sex with a younger adult man she met through an app. Believing it will be only once, Non lets herself be persuaded to try the app too. The young man she meets is obedient, awakening her taste for control, while he becomes equally addicted to the mature allure and assertive seduction of the two married women.
