My wife, Natsume, who lives with her husband in an apartment owned by her father-in-law, Tatsunori, and usually helps with cleaning the apartment. One day, Natsume, who was working in Tatsunori's room, got tired and took a nap. Tatsunori sneaks up behind Natsume, sniffing her hair and touching her body. When Natsume wakes up, what she sees is not her usual kind father-in-law, but a beast-like father-in-law who bares his glaring desires!
