Step-brother... what the hell is that on your phone? PORN?? Not just ANY porn too... porn about step-sisters? Oh wow.... then explain these many photos of ME! Wait a second... are you having naughty thoughts about ME? Your dear little step-sister? You deny it, but why are you blushing...? Ooooo .... so if I were to just tease you, it wouldn't be a problem, would it? I mean, if you AREN'T turned on by your little step-sister, then if I were to unbutton this top it shouldn't matter, RIGHT? You wouldn't get turned on... or would you?
