Step sister educates me about sex while we watch TV

I was chilling with my step sister on the couch, flipping through channels when she caught me staring at her feet. She playfully teased me, telling me how much she loved it when guys stare at her feet. I've always been into that kind of thing and she found it hilarious. So, I decided to give her a little taste of what it feels like to have someone staring at her feet. Surprisingly, she seemed to enjoy it and we ended up getting pretty heated up. She's always been the kind of girl who likes to keep things professional, especially around her family. But there's something about our chemistry that just clicks. We both admitted to ourselves that we've had some kind of attraction for each other for a while now. We're not blood related but she's definitely the hottest step sister a guy could ever have. Anyway, we continued our little game, transitioning from just teasing and flirting to actually fucking. It was a wild ride, but one that I wouldn't mind repeating.
