My stepmom with a big ass gives me a blowjob in private

I've been walking around the house for a while, trying to find something to do. I was just about to head upstairs when my stepmom walked in, and we started talking. She's got a big ass, and I couldn't help but stare at it. She noticed me looking and asked what was wrong. I told her that I wanted to see more of her, and she didn't seem to mind. She took off her clothes and let me touch her big ass. Then, she went down on me, giving me a blowjob. It was pretty hot, and I enjoyed it a lot. She's not my mom, but she's still my stepmom, and I don't mind if we do stuff like this again.
