A resident named Isao from a certain apartment complex, who had long disliked the filthy room next door, finally went to complain about the smell. However, she was dragged into the room by a muscular physical education student and retaliated with rape. With endless, intense sexual desire, he made her cum repeatedly, while she was forced to keep smelling his sweaty body odor, leading to internal contamination. In a trance-like state, she was subjected to in-out 30 times of ejaculation into her uterus.
