After vicious bullying at school, my adult brother withdrew from society. Our mother could not abandon him and eventually even began handling his sexual needs. Then our parents died suddenly in an accident, leaving just the two of us. Still shut away in his room, he demanded that I take our mother’s place. I hated it, yet I could not bring myself to leave him. Trapped in a deeply warped codependent relationship, we continue sinking into forbidden sex day after day.
