Just read a story involving a boy and his sister when they were growing up. I had a big sister and I didn't have anything sexual to do with her but I can't say the same about one of her girlfriends.
At the time, I was 14. My big sister was 17 or 18 years old and her girlfriends were about the same age. There seem to always be a girlfriend or two over at our house all the time and most treated me like their own little brother.
There was one in particular. A red head by the name of Gail. She spent the night at our house quite often and she'd run around the house wearing her short little nighty and panties all the time. You can imagine the effect this had on me. She had very shapely sexy looking legs and when she'd set, I could easily make out the dark area between her legs made by her pubic hair. My young cock would instantly get hard.
Then, early one morning, things happened. I was up early and in the living room with the TV on. My sister was sleeping but Gail was up. Gail came into the living room and joined me. She sat across from me and what a view I had. Between seeing her beautiful thighs and that dark area between her legs, I was hard as a rock. I went to squirming on the sofa. Gail looked at me and ask 'What's the matter'? I told her nothing. Gail knew. She had boyfriends and knew exactly the effect her body had on boys. She got up and walked around the living room in front of me. She then came over and stood in front of me and ask 'Am I getting you excited'? I just looked up at her and didn't say anything. She than said 'I bet you'd like to feel these, wouldn't you?' holding her leg out. I just set looking at her leg. She then turned and sat next to me. She said 'Come on, go ahead. I don't mine' as she reached for my hand and put it on one of her thighs. It felt wonderful. She then reached over and put her hand on my cock feeling it thru my pajamas. She then ask 'Want me to take care of this for you'? All I did was let out a moan from the feel of her hand touching my cock. She then reached into the opening and pulled it out. She then went to gently doing her magic on me with her hand and before long I covered the front of my t shirt with cum.
From then on, every chance I could when no one was looking, I'd steal a quick feel of Gail's legs. When we were alone, Gail would give me a hand job while I felt her legs and touched her pussy. I found out years later that Gail had told my sister about our little sexual get togethers. I know I turned very red in the face when my sister told me this. Gail was my first love.
