I went to a 7-week all-boys summer camp as a kid from age 10-15. It was an elite sports camp for kids who wanted to get really serious about high school and college sports. Most of the young men were in really good shape to begin with but would spend a testosterone-fueled summer packing on muscle after eating and exercising all day, getting absolutely jacked and of course, tan.
In the mid 80s and early 90s, this camp had a "no-clothes" rule on the dock when swimming in the lake. So here we were, kids as young as 8-9, butt-ass naked with middle school, high school, and college athletes. At the time it seemed normal; "it's just how we do it here". But in hindsight, it was probably pretty unusual and the camp eventually did away with the "policy".
So for those still reading, the whole scene was very much like Sean Cody meets a 90s/00s Abercrombie ad campaign. It was the first time I'd seen male nudity at the pro level. I remember thinking, "holy crap, the high school and college guys are all tall, ripped, and packing. How do they get that way? How do I get that way?!"
The middle school kids were a bit of a mix. Take the 14 year olds: some were barely going thru puberty and some were full-on men with massive dicks.
In the cabin at night, every once in a while, campers would whip their dicks out and compare. Usually I would observe but not participate - until one day when I was basically dared.
I was tall for my age and an early bloomer, so I knew how I stacked up against the other guys in my cabin. Finally, I caved and whipped out my 7.5" cock which felt big at the time. It stunned the other guys who were still hovering around 5" on average. Side note: I was 6'1 at the time - and felt my dick should have been WAY bigger given my height. It still drives me nuts even though I get no complaints on the size front. LPSG isn't helping matters ;)
Before pulling it out, I got my dick as hard as I could underneath my shorts. Once hard, I pulled down my shorts and my cock flipped up against my belly button with a pop. I proceeded to caress it so it would stay hard, and pushed as much blood as could to show off my thick veins. At this point, I was kind of running up the score because I'd already won the length contest by a stretch; no one had as veiny a cock as me, so I did it almost as a victory lap.
After 10 min or so, I could feel my juices flowing and I started to worry that I might leak precum (even then I was a big precummer and could push precum out on demand - especially when trying to get my veins to pop). I definitely didn't want to blow a huge load because not many other guys had started cumming yet, so 8-10 teenage ropes might have freaked them out. "Oh my god, are you ok? Is something wrong?! Someone go get the counselor!"
Anyway, I finally put it away even though several kids kept chanting "whip it out, whip it out." I knew if I did I'd have released a flood, so I declined the invite.
The next day, we had an intra-camp swim meet down at the dock. You guessed it: completely nude. One of my core memories was this absolute unit of a jock (think Brodie from Sean Cody, but way more handsome) ahead of me in the freestyle relay lineup. He was about my height, brown hair, tan and super muscular. He had one of the bigger cocks in our age group, and he was always showing it off.
When it was his turn, he bent over as most swimmers on the starting block do. His ass cheeks spread far apart and his perfect asshole was on full display for what seemed like an eternity. As the swimmer ahead of him was on approach, he relaxed his hole and then tensed up. His asshole opened wide and then clamped shut tightly - way more than just a wink. I remember this warm (almost hot) rush washing over me - and knowing then that I was not completely straight.
I often think back to that moment and wish I could relive it in slow motion over and over again.
I've often fantasized about what it would have been like if time froze and I could have spent the next hour rimming him, massaging his prostate, and fucking him so hard that I'd pop through his second hole. I wanted to hit the right spots over and over until a flood of precum streamed uncontrollably from his thick, veiny, rock-hard 9" cock. Eventually - with him still in that swimmers starting position - I'd get to see his muscular asshole and taint spasm over and over as his huge balls pulled up to his body and his cock spewed buckets of cum like a horse.
But time didn't stop. We went on to win the relay that day (naked high fives and bro hugs all around). He would go on to play Division I lacrosse at some Ivy League school and had his pick of whomever he wanted on campus.
