You barge into my room when Im trying on lingerie for my wedding night. At first Im mad and call you a perv becuase you are obviously looking but then I apologize because I didn't mean to upset you. You mean a lot to me.. will you help me pick out something sexy to wear? I show off some other options, at one point leaning over you and noticing your boner. Oh my god! Im your fucking step-sister! You are definitely a pervert. Don;t get upset, its OK. Look I want you to feel special.. maybe I can help you out just this once.. but you swear to god you won't tell anyone. I tell you to take out your cock and oh my its sooo big. I rub it between my perky tits and can't help myself.. I start to suck you off but well... we both want more. I ride you cowgirl and reverse and your dick just feels sooo good inside me. I can feel you're about to cum so I get on my knees an suck you until you cum all over my face.
