My husband is a lazy man who doesn't work. He's also a pervert and makes me do all sorts of things. I became friends with his kind uncle, who listens to my troubles, and we started an affair. When my husband goes out to play pachinko, my uncle comes over. Those are the moments I feel happy at the moment... etc. There are all kinds of immoral affairs in this world. My husband's best friend, uncle, friend, senior, colleague... Is your wife okay? She wants to swap!? What the heck! Well then, live a naughty and fun life...
