The niece prefers to fuck with her hands tied
He always thought something was wrong with his parents. All those therapies and the money that was being spent to be able to “straighten” the girl ended up being insufficient. He always knew that she just needed understanding and support regarding the things she wanted to do and what she wanted to be. When he takes the step, he discovers that his niece prefers to fuck tied up, something that not every man can do, but he, being a slut from the same family, has no problem doing it. It’s about her happiness and if he has to fuck her like a bitch, then he’ll do it without asking.
