My stepdaughter has been begging me to take her to the gym, & I always turned her down because she’s so petite… I assumed she wouldn’t be able to keep up. I’d never really looked at her inappropriately before today. But watching her stretch in front of me, that tiny little body and her perfect, tight ass. Something was coming over me that I couldn’t resist. With her lying backward on my chest, her sweet bubble butt in my face, I was getting harder and harder. I needed her to stroke my cock - I didn’t care if she was my stepdaughter or not. She saw my monster dick, and neither of us thought it would fit inside her. But we were both so turned on, we knew we had to try at least…
