I pulled them on in front of her and the fact she was enjoying watching me dressed like that was a massive turn on and my cock was throbbing and achin... to be stroked. She told me to rub it while it was inside the panties which was increasingly difficult as my hard on was forcing my cock out. I did my best and she sat on the bed naked fingering her cunt watching me dressed in her finest I was in heaven and soon needed to cum. Please cum in my panties she instructed me and I needed no. We were fooling around in her parent's living room one time, just groping and kissing like most teen-agers do, when I told her about a fantasy of mine. I suggested that she dress up in the shortest skirt she owned, a skimpy tube-top and heels... so that she had a dirty-girl look... and we'd drive down to the public park on the lake and have sex anywhere and everywhere possible. She loved the idea and rushed off to get ready.I waited in the car for her, and when she stepped out of the house I. The first was Cindy, Mary and Martha."You still planning on setting Gail up on one of our nights out" Mary asked."I don't know yet. I'm still trying to make up my mind on whether to set Gail up, set Rob up or do them both. I'm leaning toward both. Rob is so gaga over Gail that he might just forgive her. I don't think Gail would forgive him if she caught him. If I do them both and she goes off on him hard enough it might make him pull back from her."The talking stopped when a couple more people. Things were soon back to normal and we were fine but I was soon thinking of ways to turn him on again. I tried to remind myself that he was my sister’s son but my mind and body wanted more.Late one night I saw Tom in the study room wearing only a pair of boxers having just come from the shower. He typically doesn’t dress like that to study but I was not going to complain. Wearing just a long t-shirt and a pair of panties, I fixed a drink of ice water and joined him in the study to see what he.
