Stepdaughter Claire Roos' Tight Ass

I didn’t mean to spy on my stepdaughter, Claire Roos, but I caught a glimpse of the cutie playing with her pussy. Sure, I couldn’t miss the show. I had a huge hard-on in my pants and I breathed heavily, and I think this is what disclosed my position. My sweet stepdaughter didn’t run away but asked if she could give me a blowjob in exchange for an anal experience. Can you guess my answer?
