I'm lying in my bed, feeling the heat of the night, my sister sleeping just a few feet away. I'm trying to calm myself down, but my mind is racing with dirty thoughts, my cock throbbing with anticipation.
I'd been living with my stepbrother for a few months now, and the tension between us was palpable. We'd always had a bit of a weird relationship, but since we'd started living together, it had become even more intense.
I'm feeling like a total slut, my heart racing, my breathing heavy, as I think about my stepbrother's huge cock pounding into my pussy. I've been wanting this for so long, and now that we're finally alone in the house, I know it's going to happen.
