I had just heard my Dad leave so I know it was just me and my Mom in the house, I quickly find her. I just wanna have a talk, I tell her I know we are alone and I have been having these urges. Every time I see my Mom I get all excited and I start to have these thoughts, I know they are wrong but I can not help myself she is just so hot. I tell Lexi I had enough and I need to act on my thoughts, Lexi is blown away but I do not care, I push her over and go to town. She isn’t gonna stop me I am gonna get what I need, at first, my Mom was pushing me away but after a while, I can tell she liked. I was just about to cum when I heard the door open, OH FUCK IT’S DAD!
