I have been an avid fan of Solo Touch for a long time now and have found many stories on this site to be brilliant and am glad to finally add one of my own.
I am seventeen (a virgin), still living at home with my parents and my sister (sixteen). As my sister and I are old enough to look after ourselves now, our parents are free to leave us behind and go out themselves. I had always had a thing for my sister but had never done anything about it. She and I knew she masturbated and also knew I did to, but we have never caught each other in the act.
One night when they went out, my sister and I stayed at home and decided to watch a movie. The movie had just started and it came to a part where a guy was shaving his pubes to make his dick look bigger. Just as this part in the movie passed I looked at my sis and then back at the screen. We watched the movie till the end then she went to bed.
After seeing this I decided to give this a try. I headed for the bathroom (which my sis and I shared). I trimmed my pubes first then got a razor out and a new blade and began to shave. I was nearly finished when my sis walked in to use the bathroom. She stopped in her tracks and then we looked into each others eyes for a few seconds (which seemed like eternity). She then headed towards me, took the razor out of my hand, wiped off all the sticking hair then knelt and covered my dick in moisturiser that was sitting on the sink. She then energetically jerked my dick so hard and rapidly that I came almost instantaneously. I came all over her nightie. Then again without saying a word she cleaned up and then left the bathroom and went back to bed.
I still stood there astonished with cum remaining on my dick. My fantasy had come true. I then cleaned up and headed off to bed.
The next morning, when we were having breakfast all my sis said was 'Nice hair-cut,' Not a word more or less.
