Just read about this guy name Thomas and his first with his sisters girlfriends. Just like me.
After reading about this guy Thomas, I had to write. I had a similar thing happen to me when I was 14 involving my big sister's friend. I too lived in an old rent house and the bath room had this add on door added sometime after the house was built. The door went from my sister's room to the bathroom. This one evening, I got home from football practice and headed for the bathroom to take a shower. It was a Friday and my sister had a girlfriend over. On my way through the house, I had checked her out. She was wearing some cut offs and did she ever look good. I could even see the cheeks of her ass. All this did was get me aroused and when I got to the shower, I was hard.
I got in and soaped down some. Then, I heard the door open from my sisters room. In walked her girlfriend. I turned around real quick trying to hide my hard dick from her. She just smiled and said 'It's OK. I've seen it before'. I didn't know what she was talking about and she told me about the crack between the door and the frame. She said it lines up just perfect with the shower. I felt very embarrassed, but at the same time also very excited. She said 'I've also seen you jerking off'. Now I was really embarrassed! She walked over to the shower and said 'Want me to do it for you'? I was so excited over having a girl see me and wanting to actually touch me. I slowly turned towards her. She was looking down at my cock. It was jumping with excitment. She reached in and wrapped her soft hand around it. All the while I was looking at her legs and tits. She then slowly went to stroking me and I soon blew my load. I'd never cum so much in my life. She ask 'Feel good'? I just shook my head yes. She then left the bathroom.
After this, every time I'd see her I'd get all excited and hard and she'd follow me to the bathroom and jerk me off. It was great.
