It started as a joke... When my son said, "My mother isn't a woman," I tried to seduce my son. Of course, I wasn't serious. But my son couldn't resist the temptation and pushed me down, twisting his dick inside me. I wasn't entirely against it either, and somehow I started wanting it from him too. And then I had my son's semen poured generously into my vagina. It started as a joke, but I don't regret it. Because we love each other...
