I have a fuck buddy coming over so I have you (my step bro) clean my asshole and pussy with your tongue before her gets here. I'm gonna let him fuck my ass so make sure my asshole if nice and clean! My fuck buddy shows up and you watch through the crack in the door while we fuck. We make out, I suck his cock then I take it up my ass. He fucks my ass in different positions then cums all over my butt! He leaves and I call you in to clean up the mess with your tongue !
