Next-door stepfather decides to retire and moves in with Miku and her husband. Fascinated by Miku's job as a flight attendant, he asks her to wear a costume, and unable to resist her appearance, he assaults her. Afterwards, he repeatedly torments her—masturbating in front of her, spying on her having sex with her husband. Miku, blushing and ashamed, cannot bring herself to refuse, helplessly submitting to his demands. The way she is consumed by her stepfather's desires appears strangely seductive, filled with pleasure.
