I revealed to my mother that it excites me to look at her and that I wank on her. She accepted my revelation and the story ended there. Until one day she asked me what the thought would turn me on the most and I told her that I wanted to see her get fucked by someone so hard that it would make her cry but that she had to think only of me. And so she did, she called some random guy and they started fucking while I was inside a closet window in his room. She starts being a slut and getting her ass fucked already but in the direction of this closet, so that I could see everything clearly. The guy comes pretty quickly and she decides to let him cum in her ass and asks him to continue. She opens her pussy wide and starts getting fucked like a real slut, screaming and moaning a lot. Meanwhile I was jerking off very hard and had already come twice inside his closet. For the finale she comes very close to the slit she left open, puts her face inside the slit and gets fucked until they both come and I come in front of her eyes. It was just too exciting
