you haven't hung out with your sis in so long and she wants to get to know you (the adult version of you) and ask you a sexual question... "what is your fetish?" she tells you to try not to feel weird about it but its been bugging her and she wants to know.. you're reluctant to tell her at first but then tell her that you like to watch in ces t porn. she's surprised but then tells you her fetish is tasting herself.. she wants to try out these fetishes so your step-sister starts to fuck you. "I want to taste myself on you" and starts to suck her taste off your cock. now she wants you to cum on her face! "who knows maybe that is another one of your fetishes"
