AN: I've had the idea to do this for a while, and here it is finally. This takes place a long time before rocky, longer than anything else I've written. I think...yeah. So ooooooh Riff is having funny feelings for his sister...ok just had to say that, that is actually pretty much what this is about. And I don't own rocky horror, but we are all fairly smart and know that already, right?

She was already asleep when I entered the room, or at least close to it. She had turned out the lights, the only one left being that of the moon. I could see it floating outside the window, the most beautiful thing in all of Transylvania; both dark and radiant at the same time. But Magenta's beauty outshone even that of the moon, though she denied it whenever I told her this.
She lay in bed, drowned in the subtle moonlight. She was unaware of my presence, lost in her own dreams. I stood still, afraid that I would disturb her peaceful state at the slightest movement. The moonlight played on her pale face, making her appear more beautiful than ever. Even when rid of makeup, her lips were still deep red, and her long, dark lashes spilled out around her closed eyes. One red curl lay separate from the rest that framed her face, falling disobediently in front of her closed eyes. I wanted to push it away, to fully uncover her face, but I was afraid of waking her.
I walked across the room to my bed where my nightclothes lay, just as I had left them. I undressed and changed, leaving my clothing on the floor, not bothering to but them away. Ignoring own bed in front of me, I walked through the darkness over to Magenta's, sitting down next to her, softly, as not to disturb her. I touched my fingers to the strands of red that had made their way in front of her face, pushing them away. She stirred slightly, her eyes opening, framed by dark lashes. Silently, she pushed the covers back and moved over slightly, and I accepted her invitation by laying down next to her. I pulled the covers back up around us, wrapping my arms around my sister. She relaxed against me and closed her eyes once more, her head resting against my chest. I let my hand trail up and down her spine, knowing how this motion soothed her. I could feel each slow breath she took, from the slight pressing of her chest to mine, and her warm breath on my neck. The thin, dark fabric felt soft and smooth against my fingers, and I could tell that she wore nothing underneath. I wanted to wrap my arms around her tighter, to feel her body pressed against mine. I did nothing though, for I could tell that she had drifted to sleep now, and I did not want to wake her.
I kept stroking her, running my fingers slowly over her back. The fabric of her nightgown lay stubbornly over her bare skin, which I wanted so badly to touch. She had lay in my arms on the verge of sleep countless times before, but I had never longed for anything more than that, as I did now. I wanted to be closer to her, as close as possible. I wanted to slip my hands underneath the dark fabric, to explore her body, touch her everywhere, not only her back.
I forced these thoughts from my head, looking back down at my sister, still unaware of any of this. I supposed it was best that she did not know, for it may have scared her. It scared me. She was my sister, and I loved her, she loved me, but I was not supposed to want her that way. My sister, I repeated to myself, finally letting sleep wash over me as it had Magenta. My sister, that was all.
