The sound of a buzzer from the apartment's intercom suddenly cut through the air, interrupting the game Andrew and Nick were playing, forcing the former to pause it. "That's probably the mail," Andrew declared, and as the incredibly heavy-set orange-furred fox stood up, Nick felt the cushions underneath him shift from the sudden lack of weight on the other two thirds of the sofa. Nick had to lean back as far as he could to make room for Andrew to scoot past him, and even then Andrew's tail brushed across his face.

With nothing better to do, Nick turned in his seat to watch Andrew buzz in the visitor. In contrast to Andrew, whose clothes all were in sizes with more X's than L's, Nick was merely a bit chubby, with thick thighs to accompany his waistline. As a rabbit he had large feet too, along with a thick collar of light brown fluff around his neck, plus darker brown strands of fur hanging from the tips of his long, floppy ears. He'd come over to Andrew's just to hang out for a while, so both were dressed casually, with Nick in a t-shirt and jeans while Andrew wore a sweatshirt and sweatpants that both strained around his immense form.

When the door opened, Nick barely caught sight of someone in a uniform handing over a package once Andrew signed for it. As Andrew wobbled his way back towards the living room, Nick inquired, "What's in the box? Snacks?"

Chuckling, Andrew shook his head and set the box down on the counter in the kitchen area of the apartment. "No, it's from Ardyl."

"Ahh." Ardyl was a mutual friend of theirs, a dragon who described himself as 'a prodigy in the field of materials science,' but to Andrew and Nick he was 'the rubber maker'. Smirking, Nick leaned over the back of the sofa and jibed, "He's still on the endless quest to make something that can hold up to you?"

"Well... yes," Andrew answered with a chuckle. "Maybe he'll actually pull it off some day."

"Good luck with that," Nick joked, flashing Andrew a grin. "You could fill an oil drum with pre at the slightest provocation, no need to even cum."

"Oh, come on, I'm not THAT bad," Andrew protested, leaning on the box and heavily indenting the top of it as he did.

"Yes you are!" Nick insisted, "Remember last winter?"

"I wasn't trying to hold back, that doesn't count."

"Okay, what about the grocery store?"

Andrew rubbed the back of his head with one hand. "Look, I don't know why that guy was wearing skin-tight latex, or why he bent over right in front of me, but..."

"Come on, man," Nick pressed playfully, "I'm a rabbit, and yet I think you've got a ridiculously high libido, to say nothing of your actual output."

"I can keep it under control if I want to!" Andrew stressed, "I just haven't needed to, that's all."

Nick turned around fully to face Andrew, kneeling on the sofa cushion. "Then prove it," he challenged, pointing at the fox, "Pick the strongest thing that Ardyl just sent you, put it on, and head out for a day on the town with me. I bet you can't make the whole afternoon without causing yet another tsunami of cum."

Andrew put his hands on his hips and met Nick's gaze. "Of course I can! I have control of myself!"

"Then prove it!"

After narrowing his eyes for a moment, Andrew pulled open a drawer and took out some scissors, cutting through the tape holding the box shut. "Fine, you're on," he agreed, "What do I get if I win?"

Nick chuckled briefly. "We can worry about that if it happens, which it won't. But I'll pay for everything today at least."

"Everything?" Andrew inquired, arching an eyebrow.

"Everything, just don't expect a five-star gourmet meal," Nick answered.

"Good enough." Opening up the box, Andrew reached inside of it and rummaged around, taking a few things out to dig further down – Nick could see sheets, discs, and even clothes made of a dark gray rubbery material, presumably the latest iteration of Ardyl's special formula. Every time he came up with a new variant with improved stretchiness, durability or elasticity, he'd send some to Andrew for testing, of a sort.

With a little searching, Andrew found what he was looking for and held it up. At a glance it was just a disc with thick edges, but both of them knew from past experience that it was actually a condom. "I'll be right back," Andrew declared while waving the condom at Nick, "I'm going to get changed real quick."

"Into something stretchier?" Nick teased with a wink.

Andrew rolled his eyes. "Yes, but to account for lunch, not because I'm going to lose control," he quipped back. "If there IS a little leak, not that there will be, but if there is, it wouldn't hurt to have pants that won't rip open so easily either."

Nick turned around and slid back into his seat on the sofa, facing the TV where the game was still paused. "Go ahead, then. And after that I need to finish beating you before we head out!"

--------------------

And so, once they were ready the two of them headed out to go get lunch, with the fox now wearing the stretchiest pair of sweatpants he owned. They were spacious enough to almost conceal the bulge he was packing between his legs, where he had secured Ardyl's condom over his sheath. They took Andrew's car, and Nick gave him directions not to any particularly fancy restaurant, but to a barbeque place that had everything: great food, reasonable prices, and a booth large enough for Andrew to fit into.

So far, Andrew had been confident. A day out on the town? Easy! Lunch would come first, then a movie after to relax during, and they could poke around the mall after the movie for a bit before heading home. However, just as Andrew began turning his thoughts towards what he could ask for when he won the bet, a draconic waiter came over to give them some menus and tell them about the day's specials.

The menus weren't what really caught Andrew's attention though; it was the waiter's jeans and the broad hips and plump ass the denim fabric was valiantly straining to contain. The dragon's shirt was also having a rough time attempting to contain a prodigious red-scaled gut, but the curves of his ass were truly–

"Sir?"

Andrew snapped out of his thoughts, realizing not just that he'd been staring, but that his loins were stirring, and he quickly pressed his legs together. "Sorry, what was that?" he asked, looking up, seeing the waiter expectantly holding a notepad and a pencil.

A tiny smirk flickered across the waiter's face. "Would you like something to drink?" he repeated.

"Oh, uh..." Andrew's eyes flicked over to the menu, and he asked for the very first soda his gaze fell upon. The waiter nodded and took note of it before leaving them with the menus, and with every step he took, his denim-clad backside bounced and jiggled as much as his clothing would allow it to.

Andrew gulped nervously, shifting in his seat. This was going to be harder than he had anticipated.

Nick, meanwhile, was trying not to grin too widely, taking note of Andrew's reaction and knowing exactly what had prompted it. He kept it to himself though, instead striking up some innocuous conversation about what he'd been up to recently... while still taking note of every time Andrew's gaze started wandering when the waiter passed by while serving other tables. He seemed even more distracted when the waiter came back with their drinks to take their food order, and he knew Andrew was flustered when the fox only ordered a single large rack of ribs for himself. A lot of food for most, maybe, but for Andrew, it wasn't much at all...

Once the waiter came by with their food, Nick leaned over and stopped holding back. "Seems like there's some other kind of meat you're interested in, isn't there?" he teased.

Andrew, who had been reaching out for his cutlery, froze and glanced at Nick. "Er, what?"

"You don't seem very hungry," Nick remarked, tapping his fork against the edge of Andrew's plate. "Only one full plate? Are you saving room for dinner?" Leaning against Andrew's side, he went on, "...or is there something else on your mind?"

Andrew huffed and played dumb, glancing aside. "I don't know what you're talking about," he insisted.

"Maybe you're looking for something fattier? You're not exactly lean yourself, and neither's the guy you've been checking out..."

"Speak for yourself," Andrew muttered, reaching over and giving Nick a light poke in the belly.

Nick ignored it, however. "Oh, I'm nothing compared to you, or to the waiter. Why don't you ask him for his number? I won't mind... that way you can have something to take home, right?"

Andrew's gaze was wandering again, and Nick followed it, spotting the waiter bending over at another table to put down some drinks. "Go on, think of all the fun you two could have," Nick whispered conspiratorially while casually grabbing his own knife and fork. "He seems like a pretty friendly guy, you'd get along great!"

"I'm trying to eat," Andrew muttered grumpily, taking his gaze away from the waiter for just a couple of seconds before glancing back up again when he thought Nick wasn't looking. Smirking, Nick leaned back in his seat next to Andrew and took the chance to peek between the fox's legs – his previously spacious pants now had just a bit of a bulge at the front. Not enough to be all that noticeable, yet, but it was a start...

Between mouthfuls of food, Nick continued to tease the flustered fox any time the waiter came into their line of sight, making Andrew squirm in his seat, the faux leather booth creaking with every movement. And when the time came to pay, Nick waved the waiter over and put on his best smile as he held out his card. "And by the way, my friend here would like–"

"Oh, I'm fine," Andrew cut in abruptly.

"Are you sure?" Nick remarked playfully.

"Yes, I'm sure."

"Are you sure you're sure?"

The waiter, who had been glancing back and forth between the two of them, cleared his throat. "Dessert?" he offered.

"Not today, it seems," Nick answered, pretending to pout. "Are you here often?"

"Every weekend," the waiter replied. "I hope I'll see you both again!"

"We both feel the same, trust me," Nick said with a huge grin, nudging Andrew with an elbow. The fox grumpily huffed again as the waiter walked off, his plentiful assets bouncing, and Nick gave a low chuckle. "Well, you've lasted this long, I'm surprised."

"Not for a lack of trying on your part," Andrew grumbled.

"Aww, you're fine." Nick stood up and stretched, taking his card back when the waiter returned with it, the receipt, and a few mints, one of which Nick offered to Andrew. "Let's head over to the theater, they've got a good line-up right now. I was checking earlier and I think I know a movie you'd like..."

Andrew paused in his unwrapping of the mint. "Oh?"

Coyly, Nick answered, "It just came out, but I've heard good reviews. You'll see."

Back they went to Andrew's car, and Nick smugly took note of the bulge in Andrew's pants. Bigger than it had been when he checked earlier, it was now more readily noticeable; the fabric wasn't overly stretched around it but the curve bulging out from his crotch wasn't subtle. As they left, it was the waiter's turn to stare as he caught sight of them leaving, and the smirk he flashed to Andrew only flustered the fox even more than he already was.

It was a short but quiet drive over to the mall as Andrew tried to keep his focus on other things. He was able to find a parking spot not too far away from the entrance that led directly into the theater, and Nick took the lead, grabbing Andrew by the wrist – the rabbit didn't have a hope of actually dragging the heavyset fox anywhere, but he led the way regardless. Andrew grumbled as he followed, having to push both of the double-doors open for his large frame to fit through, helping to clear a path through the other theater-goers. With Nick in the lead they first went to the ticket desk, then to the concessions, where Nick got a jumbo bucket of popcorn with extra butter to try and tempt Andrew with.

Once in the theater, it took quite a bit of squeezing for Andrew to get between the back row of seats and the row in front of it, and it proved to be an even greater ordeal to fit into the seat itself, leading to the bulge in his pants ending up fully on top of his legs where it wobbled about briefly once he stopped moving. Settling into his own seat, with the popcorn bucket in his lap and Andrew's left arm completely covering the armrest, Nick smirked a little at the sight of the swelling in Andrew's sweatpants. He may not have won yet, but it was only a matter of time...

Within a few minutes the lights dimmed, but they had to wait through all the trailers first. After five minutes with no end of them in sight, Nick leaned over towards Andrew and held up the popcorn bucket towards him. "Want some?"

Andrew tried to act stoic, but Nick could see the fox's nostrils flare at the small of all the butter. "No, thanks."

"Aww, come on, you can't come to the theater and not have any popcorn," Nick insisted, shaking the bucket a little bit. "There's plenty here for both of us, even with how much you can pack away," he added, giving Andrew's gut a gentle nudge with his elbow.

"I'm not hungry," Andrew insisted.

"Yeah, right, I've seen you eat three times as much in one sitting," Nick teased, raising his voice slightly to be heard over the trailers. When Andrew didn't reply, Nick crunched down another handful of popcorn before reaching over and prodding Andrew's belly. "You've got plenty of room in here. Heck, I think it's impossible for you to actually be full."

Andrew tried to shift a bit, as much as he could within the chair he was wedged into. "Fine, just one handful," he groused, reaching over, and Nick let him grab a bunch of pieces of popcorn, crunching into some of them a moment later. For a moment, Andrew paused, then mused, "Huh, this is really good," before wolfing down the rest of the handful and reaching for more.

Smirking, Nick held the popcorn bucket closer. "Told ya," he teased. Just as Andrew was munching away on the next handful, Nick reached over and put a hand on Andrew's belly, spreading out his fingers and rubbing in a circle. "Always got more room in here, especially for something tasty, huh?" Andrew huffed briefly, half-closing his eyes, and Nick teased further, "How else are you going to keep that belly so big, huh?"

Andrew grumbled and took more popcorn; in response, Nick gave Andrew's gut a playful squeeze, making the fat fox squirm. "Do you want the whole bucket? I can go get another one, these trailers are still going on for like 10 more minutes, and I know you could pack this whole thing away and still have room for another."

As Nick continued to play with Andrew's belly, Andrew shivered slightly, gently pushing Nick's hand away. The rabbit chuckled and remarked, "Oh, I get it," before reaching over again, this time prodding the substantial swelling resting on top of Andrew's legs. "Worried about this, huh? Having second thoughts about our bet?"

"Of course not," Andrew retorted, grateful that they were in the back row and nobody else was close to them. "But you're cheating."

"Nuh-uh," Nick said, shaking his head and prodding the bulge again; underneath Andrew's sweatpants, the swollen, precum-filled condom sloshed, making Andrew tense up in his seat. "You said you could keep it all under control. If you can't handle even a tiny bit of teasing, that just proves my point."

Andrew grumbled, but didn't argue any further, and Nick leaned back in his chair smugly, munching on popcorn. When the trailers finally ended and the movie began, Nick watched the introductory scene while he ate; it was a spy thriller movie, and opened with the villain's theft of something that would no doubt be important later. As soon as the movie shifted scenes, though, Nick snuck his hand back into Andrew's lap; with the fox distracted, it was easy for him to give Andrew a firm grope at the base of the bulge in his sweatpants, making him gasp aloud in response.

"Hmm, is this bigger than it was when we came in?" Nick whispered. Grasping tighter for a moment, now that the theater was a bit quieter, they could both hear the rubbery squeak produced, and Nick smirked as Andrew's ears pricked up from the sound.

"N-No," Andrew tried to insist, pushing Nick's hand away, but Nick could hear the splurt and see the rubber expand a bit more as Andrew's potency led to a hefty shot of precum further filling the condom. Smirking, Nick went back to watching the movie, but every time Andrew let his guard down again and the movie got slow, Nick reached over to grope and squeeze the fat fox's crotch. There was always a rubbery noise from the motion, and more often than not it was quickly followed by the quiet sound of creaking as the rubber had to expand to accommodate the ever-growing amount of fluid inside of it.

While his pants were still holding it in, the bulge was getting ever more obvious, straining against the fabric of the sweatpants trying to contain it. So, with a smirk, once the next action sequence in the movie ended, Nick left the popcorn bucket in his seat and got up just enough to slide over and sit himself down in Andrew's lap... or try to, anyway. The bulge larger than a basketball took up Andrew's lap already, so instead Nick sat down on Andrew's leg, the rabbit's rump shoving the protrusion stretching the sweatpants aside with another squeak from the rubber underneath, and an accompanying squirm from Andrew.

Keeping his eyes on the movie, Nick continued to watch while occasionally shifting about in Andrew's lap to push the swollen rubber this way and that with his back and butt. He could feel Andrew wriggling in place and huffing to himself grumpily in between the groans through clenched teeth, and now and then Nick felt the bulge against his back wobble and jiggle on its own when Andrew unleashed another splurt of precum into it.

But then, to Nick's surprise, he got some help from the movie itself. During the action scene playing out on the big screen, the main character sabotaged some of the villain's machines at his secret base, causing them to run out of control. And one of them began pumping liquid into a storage container uncontrollably, seemingly just a background detail at first until Nick noticed the camera shots kept showing it again and again, each time fuller than before.

As the sides of the metal tank began to buckle and expand outwards, even Nick felt himself getting riled up by the sight, his pants getting uncomfortably tight. It was even worse for Andrew, though, and he could hear the fox's breaths as the movie went to great lengths to make it clear the storage tank was going to blow: popping rivets, buckling metal, ominous groaning and creaking sounds, even gauges with the needles jammed all the way to the right as far as they could go.

At last the protagonist noticed the imminent disaster and fled from the room as the villain's guards started to give chase – only for the tank to finally reach its limit. The metal protested with loud groans, and pipes and valves creaked and rattled, reaching a crescendo before the tank split open along the side. A tidal wave of some frothy fluid spilled out, washing away the guards, shown again from multiple angles, the last replay in slow motion, before the camera shifted back to show the protagonist making his escape.

"Oh, wow," Nick muttered quietly, hearing Andrew huffing behind him. He felt the growing mass of Andrew's pants bulge wobbling heavily against him as thicker and heavier bursts of precum erupted into it, with the scene having clearly taken them both by surprise. "Is that going to be a preview of what happens to Ardyl's rubber later?"

Andrew gave a quiet groan and started to stand up, dumping Nick out from his lap and onto the floor. The entire swelling in his pants sloshed loudly and wobbled around, spilling over the back of the empty seat in front of Andrew. It was impressive that the pants were still holding up, but he'd filled the condom so much that it was getting to the point of being encumbering, and reaching down as Nick got back up, Andrew began stuffing the condom underneath his shirt to get it out of the way and make more space.

Yet with every movement he made, and every time he pressed on it, the rubber vessel creaked and groaned in protest, stretched heavily by the precum inside. Getting it under his shirt was an ordeal enough that some people a few rows down turned around to see what the noise was about, and Andrew quickly began making as hasty an exit as he could in the narrow space between the seat rows, with Nick grabbing the popcorn bucket and following along behind hoping the tent in his pants wouldn't be too obvious. On top of that, Andrew's flow hadn't stopped – the rubber was still getting bigger, stretching his shirt out further, and he fumbled to try and pull his pants up enough to prevent the condom being visible between his waistband and the bottom of his shirt.

Blinking as they emerged from the dark theater, Andrew huffed and made his way through the nearest exit, only to end up in the mall concourse rather than the parking lot, the rubber under his clothing giving a squeak each time he moved. "Wait, where...?" he began in a flustered tone, constantly adjusting his clothing to try and hide the expanding bulge underneath it, his shirt producing a far more prominent outline. The concourse was big and open with a roofless design, featuring multiple floors, each upper level edged with tubular railings and glass panels.

"Straight ahead then left will take us back to the parking lot," Nick helpfully informed Andrew, tossing some popcorn into his mouth. The fox gave Nick a suspicious look, but Nick simply pointed to a nearby hanging sign that offered directions. As Andrew turned away and began shuffling along, Nick smirked to himself; he didn't need to tease Andrew any more. He knew from the way Andrew was acting that the fox had already passed the point of no return, and he merely needed to bide his time.

After all, there was a feedback loop now: each time Andrew waddled another step forward, his 'gut' wobbled and the rubber pressed against his prodigious belly, making him add another burst of precum to the condom, so that on the next step it was even bigger and pressed against more of him and squeaked even louder. People were staring, and Andrew was taking heavy breaths, a look of concentration on his face as hurried through the mall towards the intersection ahead.

Smugly quiet, Nick followed along, snacking on popcorn and keeping his eyes on Andrew's wobbling body, particularly the growing bulge at the front that was becoming more and more obviously not just the fox's own prominent waistline. Andrew had to know he was on borrowed time, but still he hurried onwards, reaching the intersection with a big statue and some benches...

He tried to head up the small step into the raised center of the square, but he was in too much of a hurry and tripped, falling forward. It was truly a testament to the strength of Ardyl's rubber that when Andrew's substantial weight fell onto the condom it didn't burst on the spot, but it did produce a loud creak of protest, and Andrew sank into it like a waterbed before rebounding a little and bouncing upwards. Flailing his legs to try and regain his footing, he instead ended up shifting his weight, rocking his hips against the rubber beneath him, and that combined with the rubbery squeaking noise produced was the final straw.

"Ohhh... fuu...!"

As Nick smugly watched with a mouthful of popcorn, Andrew moaned loudly from feeling his climax hit him. Immediately the bulge in his clothing, already resembling an overstuffed body pillow, bulged out to twice its size and strained his clothes to their limit. Losing himself in the moment, Andrew mindlessly humped against the rubber vessel he was perched on, blasting another thick eruption of cum into it, and his clothes lost their battles, the shirt bursting open while his pants ripped apart at the seams.

The gray rubber condom spilled forth, free from its confines, wobbling heavily underneath the fox of a similar size perched on top of it. His pants hung in tatters around his legs, with his huge, heavy balls resting on the back of the rubber container currently serving as his waterbed. As other people nearby watched in shock, Nick casually strolled closer to Andrew, and when the fox's balls next clenched the resulting surge of cum bloated the rubber out even further with an enormous eruption that brought the rubber to twice the size of Andrew. Nick deftly climbed up onto the condom behind Andrew and sat down on it, just in time for the next blast of fox jizz to raise them both up even higher.

Forgetting about the mall-goers, Nick, and the bet, Andrew mindlessly humped into the ballooning condom underneath him; an even bigger wave of cum from him brought him and Nick level with the second floor of the mall. Around them, some people were fleeing while others watched, all while Nick snacked on handfuls of popcorn, grinning like a madman; he knew Andrew would be at this for a while, and he was here for the whole ride.

Over and over Andrew moaned and swelled the condom ever bigger than before; if anything, as his climax went on, it seemed as if he was pumping out ever more cum. He sprawled out atop the gray rubber, eyes rolled back as he rocked his hips into it while his cock throbbed and fired one enormous blast of cum after another into it, his arms rubbing and caressing the stretched surface. The entire condom wobbled underneath them, and as they reached the third floor of the mall, at last the extra-strong rubber from Ardyl began to protest against the abuse it was going through.

At first it was just a gentle creaking sound like a balloon filling up – a rubber balloon the size of a hot air balloon, that is. But with every subsequent torrential gush of Andrew's semen into the ever-expanding condom, the rubber strained further to keep its contents within itself. Not that he could have stopped himself even if he wanted to, but he was so lost in the unexpected release that he only humped and thrusted into the rubber balloon under him all the harder. It was not only growing upwards but outwards too, wedged between the statue in the center of the intersection and the balconies at the edges. Glancing upwards, Nick was glad that the concourse lacked a roof at its top, as they were about to meet it – all that much faster with the architecture around them constraining the condom further.

Andrew panted suddenly, and Nick raised an eyebrow; surely Andrew wasn't done already, was he? But then the fox gave an even longer, louder moan as his body trembled and his balls pulled up in their sack to unload even more, lifting the both of them up through the roof and into the open air. Andrew's eruptions of cum became more powerful, but less frequent, and the two of them rose higher and higher. Pushing another handful of popcorn into his mouth, Nick looked around, able to see into the car park and across the empty space, roads, and buildings arranged around the mall.

The creaking from the condom grew louder and more insistent, and looking down, Nick could see a few spots where it seemed a bit thinner than the rest. "Go on, you can do it," he encouraged, not that Andrew really needed it, nor was he listening. Andrew rolled his hips back and thrusted forward again with a groan, sending the entire top of the condom wobbling underneath them, another thick shot of cum into the rubber lifting them higher still above the roof of the mall. As he grinded his hips into the rubber, it strained audibly once again, its immense size a testament to Ardyl's skill...

...but it wasn't enough. On the next blast of thick cream Andrew shot into it, the condom's creaking began to peak. Somewhere much further down below them the material gave way at last, and a tidal wave of cum surged out across the mall interior. Both of them plummeted downwards atop the rapidly deflating condom, while the oblivious Andrew continued to add even more cum to the mess with another huge spray of cum from his cock. Thick white fox cream surged from all directions at the intersection of the mall interior, washing away anyone foolish or horny enough to have stuck around to the very end, while the sound of the tsunami of jizz was audible to them both as they descended uncontrollably back through the open roof.

When they reached the bottom it was a landing in several feet of cum filling the interior of the mall, beginning to drain out through various exits; even with the remnants of the top of the condom between them and the thick, warm flood, they still ended up covered in it when they splashed down and slipped under the surface temporarily. Within moments the fluid level began receding and Nick surfaced his head, followed by the trembling and panting Andrew who was basking in the wake of his orgasm.

All around them, every surface was either submerged in cum, or dripping it. Every storefront, every pane of glass, and every sign were whitewashed completely. Nick grabbed his popcorn bucket before it could float away from him, even though half of it had fallen out during the sudden fall, and as the receding levels of semen slowly exposed the rest of their bodies, he gave Andrew a smack on the ass with one hand.

"Told you so!" he declared smugly, and Andrew grumpily folded his arms in silent concession.
