On a Sunday, my wife and son went out to a movie theater in the next town. Enjoying a rare day off, I was home alone when Akari Niimura, a mom friend of my wife's, visited our house, saying she wanted to discuss fertility planning. Overwhelmed by her stunning beauty and big tits, I could no longer hold back. Just with her, despite being with someone else's partner, I was shocked at how insanely erotic the experience became. Using the expert techniques only a mom friend could have, she brought me to an intense creampie climax. In the brief time my wife was away, I committed the first act of infidelity in my life.
