Bucky tried his best to act nonchalant as he walked alongside Steve down the crowded New York streets.
It was a nice day out. The sun was shining. It was warm but not hot. A nice breeze blowing around them.
But internally Bucky was screaming.
He needed to piss bad.
His bladder felt so full it could burst. It ached and throbbed in his abdomen, screaming for him to empty it now now right now and threatening to do it automatically if he didn't take action soon. The pressure and consistent dull ache were one thing, but the cramps. That's what he hated the most. These painful cramps that came and went, with each one the threat of a leak that he desperately tried to hold back.
The urge had come on strong and sudden, seemingly out of nowhere. One minute he was fine and the next he was bursting. That had been happening alot, since Hydra.
He was wearing a diaper. Steve had insisted. He often had problems with his control and sometimes not even knowing he needs to go, and frequent accidents.
Even though Bucky knew he needed to wear the diapers, he hated actually using them. No matter how much Steve told him it's okay, it's not his fault, incontinence is common, Bucky just couldn't get over it.
At home, Bucky often rushed to the bathroom when he would get that out of nowhere urge, even if sometimes he didn't make it. But now, out in public, he doesn't know what to do.
He'd promised Steve he'd use the diaper if he had a true emergency. And this certainly feels like a true emergency. But he can't do that in public. He just can't. There has to be another option.
"Steve?" Bucky says quietly, grabbing his boyfriend's hand. "I need to go!"
"There's no public bathrooms nearby, Buck. Is it an emergency?" Steve says.
Bucky bites his lip and nods, trying to resist the urge to squirm.
"Well you've got protection, it'll be okay." Steve says.
"I - I can't." Bucky grinds out, trying to subtly squeeze his thighs together.
"Bucky, there's no other option. You can't hold it long. We both know that." Steve says sympathetically.
"People will know!"
"No one will know. These are good diapers, they don't leak."
"But - but....mmmmhhh Steve!" Bucky tries to think of an explanation for why he can't, but he's too busy trying to hold his piss in but also not be obvious about it as another painful cramp hits him. He stomps his feet a couple of times and squeezes his thighs together and hopes nobody can tell.
Steve sighs, looking around to see if anyone is looking, before grabbing Bucky by the upper arm and pulling him into the nearest alleyway. He pulls them both behind the dumpster and out of sight.
"Steve it fucking stinks over here!" Bucky says, gripping his crotch tightly with both hands now that nobody can see.
Steve spins Bucky around and hugs him from behind, pulling his arms to remove his hands from his crotch.
"It's okay now, Buck. Nobody's around to see."
"Steve." Bucky chokes out, feeling a small leak escape and desperately trying to cut it off. "Please, Steve. I can't."
"You can. It's okay. It's all gonna be okay."
Steve starts trailing light kisses along Bucky's neck and jawline, nearly making Bucky lose control right there.
"Steve!" Bucky whines.
"Shhhhh. It's okay. I've got you. You can let go. Stop torturing yourself." Steve whispers into Bucky's neck.
"Please Steve I can't!" Bucky says, feeling tears burning at his eyes.
"You can. I'm here, I've got you. Nobody can see and nobody will know." Steve says, sliding a hand down to Bucky's crotch.
Bucky immediately presses both hands on top of Steve's in his crotch, pressing as if his life depends on it and crossing his legs around the hands just to try to get the right amount of pressure. It's still not enough. He feels like he's gonna lose it completely any second.
"It hurts, Stevie. I need to go so bad!" Bucky whimpers, tears nearly leaking from his eyes and piss nearly leaking from his dick.
"It doesn't have to hurt, Buck. It shouldn't hurt. You need to let go."
"I can't!" Bucky says, crying freely now.
"You can, Bucky. You need to. I'm here. I'll help you." Steve says, then his hand that isn't currently trapped between Bucky's legs is dropping from Bucky's shoulder to rest on his lower belly, right on top of his swollen, overflowing bladder.
Steve starts rubbing Bucky's bladder in slow circles, gradually pressing down harder as Bucky whines, writhing in pain and desperation.
"Steve no, please, please, Steve" Bucky begs. "Steve no, I can't, Steve I can't I can't I can't Steve aaahh Steve, n-aaaaah, Steve, please please please -"
Bucky can't hold even one more drop and his bladder spasms hard, deciding for him once and for all that he can and will. No matter how hard he clenches up, how hard he squeezes, how hard he crosses his legs and squeezes his thighs together, it's over.
He's pissing full force and even now he still feels that awful need, he had to go so bad it takes a bit for the relief to kick in but once it does, it's bliss.
Bucky slumps in Steve's arms, leaning against him with a loud sigh as his bladder drains into the diaper at long last. He can practically feel his bladder deflating, getting lighter as the padding grows hot and wet around his dick and balls, piss filling up the front of the padding before creeping backwards up the back of the diaper.
He's panting and moaning, completely lost in the ecstasy of simply no longer feeling that horrible pressing urge, and instead having it replaced with such wonderful relief.
Steve is kissing his neck again, whispering to him as he's emptying, pissing, and pissing, and pissing, it just seems to go on forever and it feels so good.
"I knew you could do it, Buck. You're doing so good. So good letting go for me. I know you were scared. I've got you. Everything will be alright."
"Mmm." Is Bucky's answer, too lost in the overwhelming relief to form a coherent thought. His stream seems never ending, still going strong with no signs of stopping even as his cock starts to perk up just from the feeling of finally pissing.
It does eventually taper off of course, and Bucky's rock hard by the time it's done. The hot, wet, squishy padding enveloping his genitals doesn't help that fact one bit.
"Hmm." Steve says, squeezing the padding around Bucky's cock as Bucky whines at the sensation. "Seems like you've got another problem, now. Can I help you with that, too?"
Bucky nods, still a little too blissed out for words.
Steve starts teasingly rubbing the swollen padding, squeezing Bucky through it as Bucky moans and throws his head back against Steve's shoulder.
When Bucky’s face turns toward his, Steve kisses him, passionate and deep, continuing to rub his boyfriend off through the wet diaper as Bucky shudders and moans into Steve's mouth.
Steve rubs and rubs, picking up the pace as Bucky moans louder, determined to get him off just for being so good and so brave for him.
It's a few minutes until Bucky’s whole body shivers, and he moans loudly as he humps into Steve's hand, shooting hot, sticky ropes of cum into the diaper, his cock sliding through it as more and more erupts from his tip until it's oozing down his shaft and onto his balls.
Steve stops rubbing when he's sure Bucky's finished, not wanting to overstimulate him.
Bucky's red faced and sweaty, slack-jawed as he turns around and pulls Steve into another kiss.
"I love you, Stevie."
"I love you too, Buck."
