Record Lap Time

[NudeBaG]

Just an idea bouncing around in my head:

A young teen boy (13-15) is an obsessive track star.
He happens to be the only/one of the only boys on the team.
While at a meet, he’s running and trying to beat his personal best time.
A female classmate points out that he’s close to setting a NEW record.
During what would definitely be a record lap, his shorts and underwear slip perfectly so as to not impede his stride.
It’s possible they even slip down and he literally RUNS out of them!
The bouncing, exposure and girls in track shorts have him aroused.
Just as he crosses the finish line for the record breaking lap, he has a powerful handsfree orgasm
