She'd only seen it within his tight ribbed t-shirts, but his muscular pecs made her pussy wet. Of course, their mother clearly didn’t approve of Dil...on. She hadn’t voiced any protestations because she knew that her opposition would simply encourage Bianca even more. So, whenever Dillon came round, their mother was dutifully pleasant to his face when both girls knew damn well she was seething inside.
