JOCKS WEAR JOCKS! (jock straps)

Wore the UA jock in my profile pic today for a 25k run. My shorts had a liner in them, but I knew that wouldn't be secure enough for my dick and balls. Had one of my other athletic jocks (I only wear those...no fashion jocks for me) lined up to wear, but remembered that my UA jock is the most comfortable. Loved the secure feeling throughout my race. Pealed everything off once I was done and saw the strap marks on my ass. Got me hard... :)
