Game of ten strokes.

Sarah player a new game with her lovers called "Ten Strokes".
They told her she would enjoy it, and that they played it a lot with each other's dates. How it worked was that one oft them would start by fucking her with ten good long strokes. After that the next one would do the same, and add ten more, making it twenty. Then he would pull out and the next would take his place and add another ten to the twenty, making it thirty. And so on. And on. The winner being the guy who lasted the longest. Most women came a lot during the game, they told her. When she asked what the winner got, they said it was up to her. Some women let the winner fuck them in the ass. Some gave him head. Sarah said the blowjob part sounded pretty good, so she agreed.
