A Distant Incest thread

Before I go over my idea I want to get a few things straight, I will only rp over pm or form, if you're interested in this then please pm me about it. If you want to add anything to my idea or change something I'm all ears, I'm not to good at making plots so I'm all open for criticism.

My idea is that YC had long since moved out of the house after graduating college and hasn't seen his little sister in over eight years. Now a senior in high school the nineteen year old (she had been held back when she was little) the girl gets the terrible news that her parents were killed in a car crash and her brother who just so happened to have moved back in town will have to be taking care of her from now on since she can't afford her own place and finish high school. But things have changed, MC has matured both mentally and physically and she had nearly forgotten all about her brother who left when she was eleven. After moving in with her brother she quickly discovers that he's a very wealthy man but he gets his wealthy from a porn magazine he owns. After roping his sister into joining the business as a model they quickly become more than just photographer and model

YC will have to be a very dominant man, different than the little boy from the pictures in their old homes. He will dominate his sister not only mentally but physically as well
