You walk in to find me, your stepsister, and your adorable girlfriend making out in the living room. You confront your girlfriend and ask why she is cheating on you, especially with your stepsister. Eviee explains that she can’t resist my big boobs, and that’s it’s not really cheating because we are both girls. You are annoyed with us but I can tell your dick is getting hard. I call you out on it and you try and deny it. I ignore you and continue to make out with your girlfriend and you act surprised with how bold we are. I finally ask if you want to join us because I know you have wanted to fuck me for a long time, step sister or not, because you are always staring at my boobs. Two girls with big natural tits are wanting to fuck you at the same time so you can’t resist.
