Hitomi My Step Sister [Final] [Mercure]

Things were going just fine until my father suddenly announced he was getting re-married, and his new wife and daughter were going to live with us. What am I supposed to do now?
My new step-mother is beautiful, but my new step-sister, Hitomi, is fascinating. She is so fragile and gentle. The way she smiles at me and tries to please me….I think she wants me. I….I think I want her. Whenever she is around me, I just want to possess her.
How far can I push her? What will she allow me to do to her?
“Please, Brother, I’ll do anything for you. Just please don’t hate me…..”
