Meguri lives a comfortable married life with her kind husband. However, she has one major problem: living with her tactless stepfather. His constant sexual harassment has left her exhausted and drained. One day, while her husband is away, Meguri falls asleep. Her stepfather discovers her unconscious form and can't resist the opportunity. Taking advantage of his son's absence, he slides aside her underwear, touches her genitals, and hungrily licks the skin where sweat and womanly scent mix. Then, he thrusts his erect cock into her and forces creampie rape upon her. Again and again, whenever he finds a chance, he violates her young, pure body, defiling her innocence without mercy.
