My father remarried, and his new wife, Aoi, turned out to be a young and beautiful woman. One day, I accidentally caught them naked, embracing each other. I didn't understand why, but a strange restlessness stirred in my chest. Unable to shake this growing tension, I asked Aoi to talk, hoping she could help me. At first, she resisted, but when she saw my rock-hard cock, her attitude slowly began to change. Before long, she started teaching me everything—patiently, thoroughly, from the very beginning.
