established relationship cynari where tighnari has a piss kink and cyno has a thing for (in kink scenes) trusting someone so completely that he'd let them have complete control over them and trust them more than himself

so when tighnari tells him he can still keep holding it, cyno believes him

and when tighnari starts teasing his bladder, pressing down on it as cyno whines in a way he never thought would ever leave his mouth, he knows that he won't so much as leak, because tighnari said so, because tighnari believes in him

just. cyno enduring hours of bladder torture because tighnari loves it and he loves tighnari taking control for a bit, and the way his whole body shudders when tighnari finally says he can let go, and even when he's dead tired afterwards, tighnari smiles and pampers him enough to make the last few hours melt away

just... Dom tighnari with a piss kink, man. his snarkiness and clever teasing would be agonizingly wonderful I think
