You know your step-sister is a whore because I fucked one of your friends. You threaten to tell mom and dad about it unless I am a whore for you too. I am grossed out and annoyed by you, but I suck your dick anyways because I don't want you to tell mom and dad. I roll my eyes, scoff, and continuously seem annoyed that I have to suck your cock. I am on my knees for you for a while and you still aren't cumming, and you decide to take it up a notch. Now, I have to fuck you! I am grossed out but let you fuck me anyways. The whole time I am riding you, I act bratty and disgusted by you. My big tits are bouncing, I roll my eyes, and insult you a bit. What kind of pervert wants to fuck his step-sister anyways? It's because you aren't fucking anyone else and got desperate, isn't it. Hurry up and come so we can get this over with. I instruct you to pull out because I don't want you to cum inside me -- gross. You cum inside me anyways because you know I am a whore and let all kinds of guys fill me up. I show your cum dripping from your step-sister's pussy and, annoyed and disgusted, kick you out of my room after you are done.
