#sheith #nsfw #piss #galraKeith Here goes the second head canon for Keith.

- It's a Galra thing that Keith is unaware about: Whenever Shiro and he make out and things get heated, Keith gets the overwhelming urge to just piss. He always either interrupts things to go to the

bathroom and relieve himself, which lingers the feeling most times. Or he ignores it and powers through!

One day he's laying on top of Shiro, their bodies aligning all the way, they kissing fervently and panting into each others mouths and Keith rocks his hips with arousal..

and suddenly there's a burst of urine coming out. Small burst, but enough to make a wet patch on both his briefs and Shir's t-shirt. He freezes in shock, tensing up all the way from 0 to 100 and sucks the air in between his teeth sharply. He lost control, holy fuck... He

splutters frantic apologies to a confused Shiro and bolts to the bathroom. First Shiro thinks that Keith must've ejaculated prematurely and that's what he's embarrassed about, but quickly he realises it's too wet, not viscous enough to be precome or thick enough to be come.

There's a warm, heady smell and things click into place (you can imagine Shiro's surprised puppy Oh-face here). He goes after Keith to comfort him, inquire what happened, and calm him down, because it's not a big deal to him. It didn't even diminish his arouse, if anything his

erection is even harder than before. Eventually they figure out together that it's a quite intense Galra instinct that has to do with marking one's mate.

Shiro gets them some water repellent mattress protection for under the sheets and even puts one on the couch, beneath the

sleeves. Now there are two places besides the shower where Keith can just let go when they do foreplay and follow his instincts, which is really important to Shiro. And he loves it, it becomes a kink VERY quickly.

That's it.. lmk your thoughts! (and share if you like <3).
