A bit too much like my sister

I awoke the next morning feeling slightly odd. First of all, I felt very sluggish. Usually, I was first up in the morning, but I could already hear Zoe in the shower of our shared bathroom. There was also a weight on my chest, and there was hair in my face. Also, it seemed my boxer had ridden well up between my asscheeks. I tried to drag it out, only to find that I wasn't wearing a boxer. I was suddenly very awake, sitting straight up in my bed. The weight on my chest shifted downwards, and I glanced down through the blonde hair to see a pair of naked breasts! I also noticed that I was in Zoe's room. Getting out of bed, I walked over to the full lenght mirror and saw the reflection of my sister. The wish from last night had worked better than I'd intended it to work. It was hard to be much more like Zoe than I now was.
