Hi I am Ed, I was sitting on my bed reading one of my 2000AD comics when Wendy, my sister Kim girlfriend, came in and sat next to me very close. She was bored. They had been swimming in the pool all day and teasing me, especially Wendy. They had on new swim suits that were so revealing they might as well been naked. I had been trying to hide my hard cock from them all day. As it was I was waiting for them to go to sleep so I could have a wank.

I am 17 and my sister is 16 there is only 10 months between us. Wendy is 16 and 4 months younger than me. We are all skinny kids but they have some nice shape boobs and both have what can be describe as puffy nipples. Their new swim suits did confirm that today. Mum will not allow Kim to use her new swim suit outside of our pool.

Wendy said “Can we talk or something, Kim has fallen asleep and I’m um, well awake and need some help to get me to sleep.” I put my comic on my bed stand and looked at her. Mistake, she was wearing a sexy baby doll nightie which was quite revealing and my cock revealed itself. “Now that is the incentive I need to sleep. Have you ever had a girl before Ed?” as she reached for my cock and stroked it. I shook my head in the negative. She smiled. “Neither have I had a boy, lets learn together tonight. Pull your shorts off whilst I close the door.”
