My step-bro was perving on my sunbathing in my bikini. He's such a perv. He's only watching because he's trying to imagine what I look like naked. Maybe if I show him then he'll stop trying to spy on me. I wonder if my bro will like what he sees? What if he gets hard for his sis?! Fuck it, I'm going in to his room right now. He better not tell anyone what I'm about to do.
