A woman is attacked by a man disguised as a delivery man. Perhaps because of her fear, she is unable to say no, so the man takes advantage of her, visiting her frequently and engaging in increasingly perverted play. The woman, unaware that this is the case, accepts the man, thinking that he will leave once he is satisfied, but her feelings gradually change to affection, and he ends up ejaculating into her anus. She even allows the ramen shop owner who visited her home to cum inside her in both holes.
