She was cuddled up close to me since her Mom was out. We were watching a movie with a very steamy sex scene and I started to get hard. She noticed before I could cover it up. playfully she poked at it and said "you should really do something about that'. I said," I need your Mom to take care of this, but she wont be home for hours".  Teasingly she rubed it a little and said "you should just take care of it yourself".  "it is better when somone else does it" I said.  With that, I unzipped my shorts and pulled it out.  She was shocked at first, but with a little coaxing she grabed it and gave it a few strokes. That was the first time that she ever touched a cock.
