2big: i too ran track in high school. i also ran the hurdles. there weren't too many tall guys running track, so i got stuck with them. we had the little 80's style nylon shorts and could not wear spandex underneath them because of uniform rules. (we all had to match). anyway, i wore my tighty-whiteys underneath my shorts even though i hated them because i bought them big for extra room for my cock. during the first track meet, running around the track my cock bounced out of the leg hole. i had placed my cock along the front of my thigh because that was the best place for it in those underwear. i had never worn them to track practice because i always wore some sort of spandex underneath my shorts, so i didnt know that i would fall out of the leg hole under the pressure created by running. i didn't fall out of the shorts completely thanks to their nylon lining, but it made me realize what had happened because i could feel my cock now on the inside liner. and feeling it in high school meant getting hard. i fell out of my underwear toward the end of the race, so i was still getting hard in my shorts as i finished the race. i did my best to conceal my hardon but just about everyone saw. it wasnt like i could hide it that easilly, it was poking out past my hip. in any case, i ended up quitting the team because of the embarrasment. it was one of my many difficult experiences as a kid dealing with having a large flaccid cock.
