Vivian and I went into the bedroom for a talk. I asked her if it was her idea or Peters. She floored me by saying it was her idea. They had watched po...n and the whole idea had got her excited. In preparation she had bought a couple of dildos. One was about 9” long and very thick. The other one was maybe 18” long and my pussy was twitching. How much of that could I take I wondered.Vivian was getting turned on as we talked and fondled the dildo. I moved in and kissed her. She was surprised at. ” Luke announced, “penalty to the girls.”The other girls let me take it and I scored.By then the score was girls 4, boys 3.I backed away from the action for a while again and soon the boys equalised.As the game went on the tingling in my pussy started to disappear so I got back into the game and ‘engineered’ another tackle from the boys. Down I went and again the buttons on my dress popped open, possibly helped by me not fastening them all when they first came undone. Again I lay there on my. I came up behind her and started pressing myself into her, moving in rhythm with her, and I waited to see if she would grind back without even knowing who it was.

Then her eyes blinked wide and she saw me looking at her. She flushed bright red, her flush disappearing into and under her T shirt. She leaped to her.
