Housewife Asami lives a quiet day. Hell arrives. Three former coworkers who went to prison after her husband reported their embezzlement come for revenge. They wait until the husband leaves, force their way into the house, and fuck her. She screams and fights and is wrecked. It does not end that day. From the next day they keep using her. They bind her slender body. The anniversary promise with her husband is not kept. She ends up going to the men herself.
