One of my earliest sexual fantasies almost became a reality one day in Middle School, when the gorgeous red head sitting next to me and the hot brown haired girl sitting behind her challenged each other to an arm wrestling match. Just as they locked up, the bell rang -- and they disengaged. What a disappointment. I had to sit there for the remainder of the class period in my tight levis acting as if everything was normal, when I was quite uncomfortable. BTW, at that time, neither would give me the time of day, although I dated both in high school.
Eight and half years later the redhead became (and still is) Mrs. Bear. Even in our advanced age, I'd still love to see the two of the them settle the issue. How's that for an arm wrestling story?
