During the New Year holidays, I went back to my wife's parents' house. There, waiting for me was my sister-in-law, who had a sexy body that she couldn't control. My Kokoro was gradually wavered by the bold seduction of my voluptuous sister-in-law, and my honest body couldn't resist and I finally had sex with her. Why would such a beautiful woman want me? Even though I had doubts, I let myself be hers and became hers.
