Hasegawa Mai, a busty and beautiful married woman who debuted from Fitch, is finally allowed to engage in SM and bondage! Mai married into the Hasegawa family as a second wife to the wealthy Hasegawa. Her husband, Hiro, had become a son-in-law seven years ago after his wife passed away. Hiro relentlessly proposed to Mai, offering to take over the debt of her hometown's factory, and they eventually married. However, the Hasegawa relatives envied this and set traps for Mai. They took advantage of Mai's vulnerability during a bondage play, which was her husband Hiro's hobby, and humiliated her by tying her up with hemp ropes and forcibly inseminating her.
