Our MILF neighbor knows i’ve been looking on her

I was sent next door to borrow a cup of sugar from Mrs. Hanson. Her stepson David is my best friend and we have been neighbors since I was just a wee one. My bedroom window is directly adjacent to hers and I take every opportunity to look on her and masturbate while watching her. Anyway, I come over to her kitchen door and she is smoking, which is my fetish, because of her. We small talk for a few minutes but out of the blue she tells me that she is aware I've been looking on her. I'm so embarrassed and I try to deny it, but she seems to think it's funny. She drops the top of her dress and drops to her knees and begins to give me a blow job. Next, she sits on the kitchen counter with her legs spread wide and I start eating her pussy. She gets off the counter and turns her ass towards me because she wants to get fucked. I fuck her hard and I can feel the cum well up deep in my balls and I cum all over her plump little ass.
