I was raped by my step-son in front of my step-mom and son

I hate that woman the most in the world. From the day my father remarried and a woman named Yoko became my stepmother, I was ostracized by my family. My father doesn't even pay attention to me, and only loves the child born to me and my stepmother. Of course, my mother-in-law doesn't care about me either. My hatred grows day by day, and I want to destroy this family...
