Misora and his wife decide to take in their father-in-law who has decided to retire. Her father-in-law, who was feeling lustful for Misora, asks the cabin attendant Misora to cosplay and attacks her. She then continues to play tricks on her by making him masturbate in front of her and watching her have sex with her son. The masochistic expression of Misora, who can't refuse and obeys despite her shyness, is irresistible.
