Threatened by my stepbrother

Hey! Get out, this is my room! What are you doing here? GO away. ...Wait, what?! How did you hear about that? Who told you I cheated on my boyfriend? You-you're not going to tell him, right?.. Please? Hey! That's not fair! Please, I can't believe you'd rat your own stepsister out. Why aren't you on my side? Ookayy... No.. I'm not going to show you my tits just because you're threatening me. C'mon, that's not cool. Seriously, what are you thinking? We're stepFAMILY! Can't you- No, I don't want my boyfriend to find out, please pleeease don't tell! Okay, okay, I'll do this but just this once! Fine, had enough? ...No?! You want me to strip for you? What the fuck. Oh my god, are you hard right now?! Your own stepsister's got your dick up. I can't believe this. You pervert! This is so wrong. Hold on, I'm NOT sucking your dick. Not even if you were the last guy on Earth! ... Fuck, please don't tell, okay okay! But ugh, promise this stays between you and me.
