At last year's reunion of ●● High School, I unexpectedly reconnected with Kana Morisawa after ten years. The quiet girl who once went unnoticed had transformed into a stunning woman, completely captivating my heart. Despite being married, I can't stop having sex with her, drawn deeper into this adulterous relationship filled with guilt and desire. Kana always dominates me with bold cowgirl positions, overwhelming me with pleasure until I've lost all will to end it. This affair with her is no longer something I can simply ignore—it's become an undeniable part of my life.
