A smiling Saejima couple who are working hard to make children every day. My wife, Kaori, has been feeling very uneasy recently. I can't help but feel like someone is watching me while I'm doing housework. One day, what I thought was an overstatement became a reality. Makoto, who is my brother-in-law, suddenly invaded and pushed me down on the bed and fucked me! Feeling guilty about her husband torments Kaori.
