I've been married for two years. I was living an ordinary but happy life... That is, until that person appeared before me again... When I met Chigusa again after 17 years, she had become a single mother. Chigusa was the first man I'd ever seen. "Naoto... don't you want to know how much lecherous we've both become since then?" What should I do when she said that... "If I don't get caught, it's not cheating..." "I'm on the pill, so cum inside me." I was confused. "Since I became a single mother, I've lost interest in romance. I just want to have a relationship where we enjoy sex. Don't you think it's not cheating if we don't get caught?" Chigusa approached me with teary eyes, and she was much more lecherous than 17 years ago... a total pervert...
