omo tropes i absolutely adore:
humping to help hold. watching someone wiggle and whimper and moan while rubbing against their hand or a pillow (or my fav: a partner's leg) is enough to make anyone's mouth water. when someone is so close to an accident that they have to distract themselves with the enticing friction of something pressing on their parts? delicious.
peeing in bottles. for dick owners, they have to try and aim their twitching cock into the hole while drops leak out of the tip. for pussys, they have to line up their pee hole with the bottle's opening, oftentimes making a mess because the piss just sprays out too aggressively. either way, it's just sooo *chefs kiss*
physically holding the pee hole shut. this is something i've tried a couple times myself and let me tell you, it's a truly magical thing. with a finger firmly pressed against someone's pee hole, you essentially cut off their option of relief completely. no matter how hard they squirm and relax and even push, nothing can come out. they're forced to sit with the maddening feeling of fullness until eventually the finger is removed and all the piss comes gushing out of them in a torrent.
begging. probably a basic answer but i don't care, i'm a whore for dirty talk. phrases like "i can't hold it much longer" or "i feel so full" or even just "please let me pee" is enough to make me instantly slick. bonus points if there's a term of authority in there like mistress or sir.
peeing outside, especially in the woods. there's something so electrifying about squatting down behind a bush or watching a stream splatter against a tree trunk or make a puddle in the dirt, especially if someone is at their absolute limit and has to find a spot for a last resort.
having to stop mid way through peeing. imagine finally, finally getting the release you crave and then all of a sudden having to shut it off. the shiver you get, the way your pee hole convulses, your bladder aching with all that liquid still trapped inside. my favorite scenarios of this include: being stumbled upon while peeing outside, someone physically pulling a character away from the toilet, a dom stopping a sub's stream just to be mean, and even the classic "i'll just pee a little to relive some pressure."
being tied up while desperate. one time i read this fic about a girl being strapped to a chair and pressed for information by this guy who kept giving her water as "mercy" since she'd been there a while. her bladder started filling and soon she was desperate and he used that to his advantage, pressing on her bulge and teasing her until she broke and told him everything in exchange for access to the bathroom. i can't remember how it ended and god i wish i could find that again, because the idea of being restrained and not even able to squirm is delicious.
the iconic pee dance. i mean come on, what's not to love? when someone's resolve finally crumbles enough for them to abandon all sense of dignity, you know they're truly at their breaking point. seeing the full package is truly a treat; i'm talking hands shoved between thighs, feet prancing back and forth, knees bending up and down, body hunched over at the waist, face scrunched in concentration, the whole ordeal. it's the sexiest sight imaginable, especially if that dance suddenly stills and a flood follows soon after.
