Izumo
-Izumo and Kotetsu (on the off chance that you don't know them, it's the pair of Chūnin that are pretty much everywhere- one of them has a bandaged face, that's Kotetsu, and the one with his right eye covered by his hair is Izumo)
-On gate duty because I said so, and Izu's moving a lot- getting up and walking around, looking out the window, etc
-I think y'all know why but imma tell you anyway. Mans has to pee
-Kotetsu does not know this because how do you tell your friend you're into that, it's just not a good casual topic of conversation
-He has noticed something's up, he just doesn't know what
-So he asks, because these two have been best friends since the Academy and you don't get this far without good communication
-Izumo is a goddamn terrible liar on the best of days, and he's already pretty distracted
-So Kotetsu knows he has to pee now
-And he's wondering why Izu's not just. Going outside to piss or something, so he cracks a joke about Izumo being a kinky bastard
-But he doesn’t deny it??? Oh shit Kotetsu was RIGHT?? DUDE THAT WAS A JOKE-
-Kotetsu finds this absolutely hilarious, and a little weird but he's also trying to figure it out. Like why would someone be into this??? He wants to know
-Izumo is embarrassed as hell but if Kotetsu wants to know why his friend gets off on having to pee he'll tell him
-There's a very awkward explanation, and it takes a while to get words in order because neither of them ever thought this would be a thing they would ever talk about
-And the boi is even more curious because, seriously, what the hell
-Izumo is openly squirming in his seat because Kotetsu knows he has to piss so why would he still try to be subtle about it
-Reasonable man, that one, Itachi and Kakashi should take notes
-Skipping forward because I can, and nothing interesting happens except Izu getting more fidgety and Kotetsu watching him curiously which makes him squirm for a different reason
-Izumo was not aware of this before now but someone standing right there, who Knows he has to go and is just watching him, is apparently also a thing he’s into
-Aaanyway, gate duty ends, Izu really fuckin has to pee, Kotetsu does too (less so) because that’s how humans work, it’s been a while
-So they go to his place, because it’s closer, and Kotetsu uses the bathroom. Izumo has to hold himself and rock a little to stop from leaking and yeah, okay, maybe Kotetsu can see why it’s appealing to watch someone else get desperate to piss but why does Izumo like feeling it himself?
-Horny shit ensues because Kotetsu asks him to wait as long as he can because curiosity and then oh hey this is hot
-Which we’re not going into the details of because the only one who can write good smut isn’t into any of this, and it’s v sad but we can’t exactly do anything about that, but basically Kotetsu ends up finding it attractive from an aesthetic point of view but he still doesn’t get it, and eventually just lets a very desperate Izumo into the bathroom
-Izu’s a little bit disappointed but that’s how it goes
