Like I said, I usually declined such "fashion" jocks because I consider them too "precious;" that is, they're too self-aware; they scream, "Look at me! Oooh! I'm so sexy!"
To me, a classic Bike jock is much hotter; a guy just grabs whatever jock's available and puts it on without thinking too much about it. This unself-consciousness makes it all the more appealing.
Nonetheless, I had bought this red lycra jock with a one-inch waistband in 1984. I wore it at the local university gym a lot. This gym had an incredibly active sauna scene; you could have either a jerk off one on one or a circle jerk almost every day. Imagine that: hot college and grad school dudes in the sauna; horny as fuck. Sounds like a fantasy, I know, but I swear to you it was real. Of course, to me, it was Heaven.
Anyway, I used to wear my skimpy workout shorts into the showers, rinse in them, and pull off the shorts and make a show of rinsing and squeezing them out while I stood in my red jockstrap, all innocent, ya know. I'd then pull off the strap and rinse it as well and hang it on the shower knob. I'd soap up, spending a good deal of time on my cock and balls, of course, and then rinse and dry and go back to my locker with the squeezed shorts and jock.
One day I decided it'd be hot if I left the jock hanging outside my locker, with the strap locked in place by the exterior combo lock. It'd hang there as a temptation. Well, it was apparently TOO much temptation, as the next day I arrived to see the combo lock broken and the jock missing! I was pissed until I remembered how many jockstraps I'd stolen over the course of my life (and thank God I grew up when all guys jocked up for sports... not like today), so I had to admire the guy's balls for going to this extreme... but wait.... inside my locker was a note saying that he'd taken the jock because he couldn't help himself, and if I wanted it back, I should call the number on the paper and he'd bring it to me. I think, tho' I can't now recall for sure, that he offered to blow me.
At any rate, I called, and he showed up and we went to the little-used stairwell off the locker room and he showed me my jock, which he was wearing and he got on his knees and sucked my cock till I shot all over his chest. I almost decided to let him keep the jock since I understood the power of the fetish, but in the end I took it back.
