A patreon reward I got from  _GreyofPta for Bun Month and I decided to add a story below.

Nick, Judy, and Zootopia belong to Disney

The story's kind of a follow up to https://www.furaffinity.net/view/40393158/

Judy Hopps was in good spirits this afternoon. She was practically hopping; in fact, the bunny Zootopia Policy officer was. Her fox partner/boyfriend Nick Wilde wasn't the first to notice, as they were walking through the halls of ZPD HQ, but he was the first to say something.
"Watch it carrots you're bouncing almost made me spill my triple blueberry latte!" he said, pulling away his much-needed caffeine before Judy almost bumped him.
"Oh, sorry Nick I've been bottling up my excitement for too long!" she spoke.
"Yeah, I could tell, usually you only Bun Butt Crush a crook twice you gave that pack leader a third dose." Nick brought his cup to take another sip, in that moment Judy bumped hips with him. The coffee and cream soaked Nicks muzzle, turning his nose white. But not a drop was spilled.
"Is someone getting jealous?"
Nick didn't say anything and used his tongue to clean his nose and muzzle.
This morning they had busted a small pack of Wolves that were extorting protection money from some downtown businesses. It had been an investigation two weeks in the making and Judy and Nick had been the ones that had taken them down. Well mostly Judy had been the one that had taken them down, Nick had helped of course providing cover fire with his dart gun, but thanks to Judy's inflatable battle suit she had quite literally flattened the pack. In its deflated state, Judy looked like she was just wearing a regular ZPD uniform. Designed by the somewhat crazy, but loveable, hyena technician Wazima the suit could take in air from valves from the suit that inflates synthetic rubber muscles in the suit. The more inflated they got the more power she could deliver in her punches, kicks, and jumps! It could be inflated manually with an air source, sometimes Judy equipped small air tanks to her belt for such an occasion or the valves could take in air instead. The latter of which was controlled by certain buttons either of Judy's gloves. At her largest size she'd been able take down bears and even a hippo. The only downside was that the more inflated it got the more…fat Judy looked. Even at its lowest setting the synthetic muscles in the seat of the suit made Judy's Booty look big and its largest sizes she could have been mistaken for a sumo wrestler. Inflated Justice, Sumo Bunny, The Big Bun, the last of which was sometimes followed by with the Big Buns, were some of the playful nicknames that had gone around the office. But Judy had taken it all in stride and even joined in on the jokes. But she was still proud to wear the suit, she and Nick had been able to blow past their case quotas on multiple occasions, and she was able to protect and fight criminals in a way no small rabbit could.
But the bust and paperwork they had done on time wasn't what Judy had been excited about. Ever since Judy was little, she loved helping with the small mammal parade in her home town. She loved helping out with decorating the floats or setting up the one or two parade balloons they had managed to get. As she had gotten older, she found out about the small mammal parade that Zootopia hosted. This one blew her home burrow's out of the water! While she loved her home festivals, even occasionally returning to visit, the one in Zootopia had more than five times the number of floats, a few dozen parade balloons along with produce and flowers from all over the world! And this year they were honoring Judy with a spot on a float for her actions in the ZPD!
Bogo was a bit hesitant at first, he didn't want to be a member short. But they reached a pact as long as Judy and Nick had brought in enough busts, he could let the ZPD's secret weapon have the rest of the afternoon off. And with this wolf pack brought in Judy and Nick had made they had made their quota and then some.
Or so Judy had thought.
"So do you wanna grab some lunch on the way to the parade site or do you wanna see if we have any leftovers in the fridge?" she asked.
"Uh, actually carrots I've got some more paperwork to do." Nick said in between sips.
Judy's ears lowered; her step lost all of her bounce for the first time this hour. "Paperwork? I thought we were done; in fact, you were doing paperwork before the bust today."
"And the day before that…and the day before that. Look I'll just be tied up for maybe an hour and a half or so. It's just some stuff for evidence and I kind of promised Marcy I'd help. Don’t' worry I'll be there before the parade starts."
"Okay, I'll see you there then."
Nick brought in Judy for a hug, and then sipped his latte. "Don't worry carrots I'll dot my I's and cross my T's as fast as I can." He pecked her on the cheek, his nose was still a bit wet.
They parted ways, Judy heading for the parking lot and Nick heading back into the office. Once Judy was out of sight, the smile Nick had been holding back all day finally graced his muzzle. His tail began to wag.
Judy stopped for a veggie burger along the way. During the drive she had been bummed out without Nick occupying the passenger seat. The only voice in the police cruiser, she had gotten permission from Bogo to take it, was the radio that was advertising the parade events today. The parade committee led by a nice older bunny had requested that Judy wear her quote special police uniform for the parade.
The committee leader was waiting for her in the parking lot when she arrived. They greeted each other and exchanged pleasantries; the leader gave Judy the rundown of the parade as they walked into one of the hangars where the parade balloons were being blown up. The hangar filled each of Judy's senses with joy. While the parade was for small mammals there were some larger species, some were predators, helping set everything up. Young cubs, kits, bunnies, were playing, eating or sneaking food, helping out, or admiring the floats and balloons. The smells of the flowers and produce, filled Judy's nose with many different flavors and combinations. She wished she hadn't eaten a veggie burger. As for the parade balloons they were mostly from mascots or cartoons, while a few were original in design.
"One more thing we've had to make some recent changes to your place in the parade." The committee leader said.
"Oh, what is it?" Judy asked. This was the first she was hearing of such a thing.
"You'll be in the same spot; however, you won't be riding in a float you'll be…helping with a parade balloon. I hope it's not too much of a bother, it's what we originally wanted to do but we weren't able to get the resources until someone reached out to us."
"Oh, it's no bother, so which balloon will I help pull?"
"Your preparation spot is back here. The committee leader led Judy back past most of the parade balloons to an open area, and ushered her to an area before leaving. When Judy arrived, her jaw dropped. Standing in the open space leaning on a helium tank was just Nick possibly drinking the same latte.
"N-nick?" was all Judy could muster.
"Hey carrots I said I'd make it." He downed the rest of his cup tossed it away into a nearby bin.
She confronted him hands on her hips. "What's going on did you lie to me?"
"I didn't exactly lie, I got all of that paperwork done this morning I just had to submit it to Marcy and I decided to eat here instead." He reached into his pocket and pulled out a few blueberries and popped them in his mouth. "Mhmmm, these are almost as good as your families. As for what's going on I'm helping. For your place in the parade they originally wanted a parade balloon bunny cop, however they weren't able to muster up the resources and time together to make one. So Wazima and I got an idea to remedy that."
"Oh, did Wazima make a balloon, where is it?" Judy turned her head from Nick and looked around. "I wonder if it'll talk." Nicks right paw slipped to the helium nozzle; his eyes were focused on a certain area of the backside of his girlfriend/partner.
He plugged the helium nozzle into one of the valves in her suit. "Oh, I think you know, it's been ready for a long time."
"Eeep! Nick!" Judy shouted, at first thinking her boyfriend/partner was being playful. She looked down and noticed the hose plugged into nozzle on the right side of her hip and followed the hose to the helium tank Nick was slowly turning on.
The hose slightly swelled as it emptied the tanks contents into Judy's suit. The first part of her suit to inflate was the seat, already making her curvy posterior even rounder and wider. Next her sleeves and pant legs swelled, making her look a bit rounder and buffer.
Judy's ears lowered, her nose twitched harder and she blushed. This expansion felt different, when she used her suit in the field she was always in control of when it was blown up. She could have pulled the helium hose let it fly around and maybe whip Nick in the muzzle or sweep him off his feet. But no, instead she stomped over to Nick, the rubber muscles in her legs added. Paws on hips she scowled at him.
"What I thought you wanted to be the center of attention? Everyone will get a better look at you and your suit's booty up in the air instead of riding on a float. You probably didn't want to ride on it anyway it was just a wooden platform with some flowers and maybe a banner. Also, Wazima has been wanting to do this test for a long time. By her calculations you could push your sumo mode some more sizes." He popped a blueberry in his muzzle and chewed.
Judy continued to scowl at him, she was slowly leaning forward. Now her suit had puffed her up three sizes, her tail becoming smaller compared to her large inflated backside. In this state if she wanted to kick Nick's butt for this trick she easily could, no had a better idea. She lunged forward; Nick yelped his arms instinctively raised to protect himself from the bloated bun fury! Instead, she pulled him into a somewhat crushing hug, pressing Nick against the inflating chest and belly of her suit.
Nick blushed a bit bewildered at first. In his mind he hadn't been certain how much his plan would blow up in his face or if Judy would go along with it.
"Thanks Nick my parents always came in second or third for the best float." He returned her hug wrapping his arms around her back and pressed himself into the inflating suit. And I've got a surprise for you, Judy thought. She eyed the helium tank's valve.
With one free paw she seized the valve turning it up, almost all the way. Filling the suit with helium had been different experience, for Judy. The helium wasn't as effective as air for her suit's rubber muscles. The lighter gas did make it easier to move in the suit but at a cost of some of the suit's strength. It hadn't been until Judy wrapped Nick in the hug that she felt the helium's attempt to lift her upward, only weighed down by the suits somewhat heavier material and her boots. Judy took some mental notes this could probably double her jump height. The increased gas flow had gone unnoticed by Nick. He was enjoying the hug a bit too much; his paws had wandered down to feel her suit's inflated seat which could have easily crushed him.
It took him a few seconds to notice that neither his nor Judy's feet touched the ground. They now hovered over the ground a few inches.
"Uh, carrots I think you need to let me go," Nick said getting worried his paws had left Judy's backside and were now trying to break her hug.
"Just a bit a little longer Nick," Judy said, a sly smile was now on her face, unseen by Nick.
Nick was getting worried, those few inches had now turned into a foot and was only climbing higher. Not only that Judy was getting the biggest he had ever seen. With this much helium in her she really was starting to look like a parade balloon. Nick was starting to get wedged in between the suit's breast. Her butt was now the size of a weather balloon. And her arms looked like they were stuffed with large balloons. Forget beating a hippo she was on the way to being the size of one!
They were now floating a few feet off the ground, when things shifted. A lot of the helium was gathering in the seat of Judy's suit, her butt was now the size the size of a weather balloon, lifting her up and shifting her body from vertical to horizontal. Nick's feet were no longer able to find purchase on the suit's belly, they were now dangling in the air. Nick wasn't sure what to do if he should hold on or try to break free. He couldn't reach the helium hose to unplug her or slide down that way. A part of him was really wishing he had let Judy know about his plan.
"Uh…Judy-" He was cut off when Judy let him slip from his grip a bit. Nick almost yelped before Judy caught him by his wrists and let him hang like he was shirt on a hangar. He looked down they were now nine feet in the air, when he looked up he saw the beautiful curvy parade float bunny girlfriend of his with a sly smile on her muzzle.
She lifted him up wrapping him in another hug and kissed him on the lips. Using just her right thumb she pressed a button on her glove that released some of the helium from vents on the back of her suit. Gently they drifted towards the ground and when they were a few feet off the ground Judy let go. He fell and landed on his butt. "Ouffff…" Nick said. He rubbed his poor posterior. Looking up Judy now floated over eight feet above him, she was almost parade ready.
"Oh, I almost forgot to get your cables hooked up." He spoke.

Almost everyone from the Meadowlands district and plenty of other Zootopia citizens came out to see the small mammal parade during the afternoon. If they weren't on the sidewalks or balconies, they were watching it on TV. There were many wonderful floats some handing out flowers, seeds, or produce. But one of the biggest stand outs was ZPD's own Judy Hopps carried by a lone Nick Wilde, he was able to carry by using boots that were weighted down that Wazima made. At first some of the parade goers thought she was just a balloon until she smiled and waved. Some laughed, cheered, some thanked Nick and Judy for their police work, others came up with some new nicknames for Judy, Blimp Bunny was pretty popular, no matter what the sight of the Judy Balloon brought smiles.
