Her boobs were trying to come out of her top. Her ass had never looked so amazing before. That was the moment that the devil inside me arose. I had ma...de up my mind.I told her to come in and took her to my room, as the computer was there only. I brought water was her and purposely spilled the water on her and this got a chance to touch her. I started teaching her how to use a computer. While teaching her I would hold her hand and she never refused. This was a good sign.I wanted to have sex but I. To this they both lifted thier tops, they had nothing on underneath, mainly because they didn't need to! but it was still a major turn on and I really started banging away at my cock.

I gingerly stepped closer to the bathroom. Gwen then made the announcement that since Becky had arrived we would stay in for dinner and she would go to the store while we got caught up.She went on her way and i had no idea what to expect.

She came over gave me a giant hug and whispered in my ear "want to play Nudist Colony?" It was a game we played ad k**s. Was what it sounded like we would sit around.
