Morning Sis

When the parents were rebuilding part of the house, my sister had to sleep on a cot in my rooom. one morning I woke up with my usual hard on and rolled over to see if she was still sleeping. I noticed she had kicked the covers off of her and her night shirt was up around her waste. The closer I looked, I could see that the panties she was wearing were about two sizes too big. Her legs were wide open and the crotch of the panties was laying to one side. I was mesmorized by the site of her pussy. I could almost smell its wonderful scent from where I was laying. I didnt care at this point I was so hard. I went over and knelt down by her and proceeded to masturbate. It only took about five pumps and I came. I crawled back in bed, and shortly after she woke up.
