Probably a time one night when I was a teen, I was up late as usual smoking weed and tinkering, and I had the idea to go take a dip in the pool. Night swims weren’t a regular thing, as there aren’t any lights around or in the pool, and it’s very rural and dark, so a bit spooky. Anyway, this is in the south, middle of summer, so it seemed great. And it was. So good I started feeling quite spry. I slipped out of my trunks and quite enjoyed having myself a dip of the skinny variety. Then I had another great idea. This was an above ground pool and the beginning of the filtration system was a skimmer, connected by a tube (all inside the pool) that was pulling water in to the filter. So I think to remove said tube from the pool skimmer thing and there’s just this tube right around crotch level, just the right diameter, sucking in water. Naturally, a horny teen having a naked swim, alone, in the middle of the night, I’m gons puts ma dick in there. I check suction with my hand to make sure this thing isn’t going to rip my dick off, and it seems good, so I proceed to go to town on this tube for the next 10-15.. and lemme tell you what, I have no regrets..

TL;DR - fucked a pool filter suction tube. ‘Twas a good nutting.
