I had quite a experience with my mom during my teens... but after her divorce and when I heard her behind my bedroom being fucked by her exbf... first it was kinda disgusting but with each time I heard it, it turned me on more and more and I also noticed the way my mom would dress around the house when he was coming over (dress, tan pantyhose or stockings) and damn... it felt so kinky in the same time and that guy was a bit younger than her..
