A former teacher reunites with a plain student he had not seen for several years. Before he knew it, Tsubomi had become a beautiful married woman. Her lovely, cute voice hadn't changed, and before he knew it, she had grown into a mature woman... Their affair begins after a chance reunion. "Teacher, cum inside me?"Tsubomi now belongs to someone else. Their creampie affair is even more pleasurable because it's dangerous for both of them. Lewd naked bodies and obscene ways of orgasming. They know it's wrong, but they end up getting addicted to creampie sex, seeking each other over and over again.
