My sexual partner at that time was my girlfriend's mother. (Miike Koharu, ALDN-608)

I am Yuta. I've been married for three years. Our long-awaited child has arrived. Since the birth, my wife's mood has worsened more and more, and I can't find joy in our lives. One day, I met my wife's mother, Ms. Koharu, again. Actually, I had a somewhat ambiguous relationship with Ms. Koharu, but my wife and Ms. Koharu are now estranged. Meeting her again after six years brings back memories... the days of being pursued. A mother's deep longing for her daughter. The struggle I feel for my wife and child. When these emotions intertwine, we prepare ourselves... for a sexual relationship with my wife's mother. Re-experiencing physical pleasure after six years. I become obsessed with Ms. Koharu...
