I was either a freshman or sophomore in high school and had PE in the afternoon. We had finished whatever activity we had that day and the coach had sent us off to do laps around the track before heading back to the locker room. In the grassy area inside the track all of the field equipment was set up: shot put, long jump, high jump and whatever else. The high jump bar and the huge cushion for landing were at one end of the field inside one of the track's curves.
While we were doing our laps, one of the sports teams was out doing warm ups. I don't think I ever found out which team they were, but they were older than us and definitely bigger. Suddenly there was an outburst of noise from the jocks and sort of a fight and then one guy was hoisted up in the air and was being carried toward the high jump area. While they were carrying him some of the guys began wrestling down the guy's gym shorts till they were down around his knees while the guy yelled and hollered.
When they got to the high jump cushion they let him down and proceeded to "pants him" and someone was soon waving the captured gym shorts in the air. Next the got his gym shirt off and he was struggling there in just his jock and shoes. Our PE class meanwhile continued to run our laps. I'm sure a lot of guys would have liked to stop and watch, but for whatever reason we just kept going. I could hardly keep my eyes in my head, especially when we were rounding that turn and were only a few feet from these goings on.
The jocks then turned their teammate over onto his stomach on the high jump pad and held him down while he howled and struggled. One guy stepped up and began delivering a searing spanking while the others shouted the count: "One! Two! Three!..." up to seventeen. We had all figured out that it was a birthday spanking by that point. The guy's ass was definitely red and they held him down a while longer, laughing and horsing around. I got a good look while we ran by -- it was one of the most exciting and erotic things I can remember from high school.
Another guy then decided to take HIS turn giving the spanking and the birthday boy tried very hard to break free at that point yelling that he only had to take one spanking. But they pinned him again and the second guy started giving it to him. You could here the swats even from the far end of the track. All the guys in my PE class were smiling nervously and making remarks to each other. After a while people were saying things like, "_s_h_i_t_! they're killing the guy!"
There was sort of a free for all at the end with all the jocks reaching over to land a few whacks and then they let him up and they ran away to the outer field where they were working out, waving his gym shorts and shirt in the air. The guy stood up and rubbed his ass and looked incredibly embarassed. He was trying to smile and take it all in good humor but it was clear he was in real pain. It was so incredibly _s_e_x_y to see him standing there in just his jock in broad daylight rubbing his asscheeks and looking embarassed, vulnerable, tender.....
In just a couple minutes we were done and he ran with us in just his jock and his shoes back to the gym, hiding his nakedness by running on the far side of us so that no one looking over from the classrooms would see him. We all got a nice close-up view of his ass and of him. He was tall, slim, and very goodlooking (at least I though so). Every now and then I see a guy with his build or who looks a bit like him and the whole scene plays again in my mind. I never did find out his name, but I sure replayed his birthday spanking in my mind as a jerk-off fantasy for years. Still do as a matter of fact.
