Fucked up StepSister

You should only be with me. and i am so sick of every person that you're with. i'm an overprotective stepsister, and i think the only person that you should allow touching your dick is me because i know exactly what you want and how you want it. and don't act like you don't want it either. because i know you do and i'm a size queen, and i know you have such a big dick hiding beneath those pants, you're gonna fuck me. and only me and if you do, you promise not to fuck any other woman in your life?
