You get a text from your wife to meet her at her step-sister's. You're not sure why, but of course you listen. You show up and... your wife isn't there. Her hot step-sister is though! With sexy lace and fishnet lingerie on. You're instantly hard even though you know you shouldn't be. She's on a mission to get your cock though, and there's no way you can resist. Why not, it's just sex right? You've always wanted this.

Blowjob, sex, then cum on my amazing ass!
