Three years after my divorce, I was living a peaceful family life with my two sons. However, as I watched them gradually grow into young men, I began to feel my desires rising day by day. One day, driven by too much alcohol, I ended up seducing my younger brother, Ryo. From that day on, Ryo started showing interest in my back and my big ass, slowly beginning to touch my body, caress me, and passionately pursue me. Although I never intended to have such a relationship with my sons, my involvement with Ryo deepened—and eventually, my son Taito caught us in the act.
