Stepmom fingers my ass (Holly West)taboo handjob

I don't know what the obsession is but I can't stop following my step mom around the house. I have to be near her. My step-dad really scored when he married her and I secretly wish they were only dating instead of married so that I may have a chance to swoon her away from him. I know I'm just a young guy who's barely legal but I know a great woman when I see her and my step mom is the best. I was heading out to the pool today and caught her from the corner of my eye as she was digging in her garden. She was bent over in her tight shorts with her round ass moving up and down. I could hardly contain myself and felt my erection immediately. I moved closer to her without knowing what I would say if she noticed me, which she did.
