The Humper Pumper

Helen said she always liked a challenge when it came to designing toys and this had certainly been one. The idea had been comparatively simple, offered by one of her many valued clients, and it had immediately caught her attention. What if when you pushed into your partner's pussy or ass the stroke of your cock was like the piston of a pump? So each thrust would pump them tighter. And so the idea of the humper pumper mod had been born. The effect would be comparatively simple to fake, a simple sensor to detect the incoming cock and an internal tank to add the extra air. If you wanted to put a little more effort in programming the amount of puff to match the depth of the stroke would be easy enough. But such simple fakery was beneath Helen, and a tank like that was sure to run empty long before you could really enjoy the results. If you were going to fake it you might as well ask your partner to breath in in time to your humps. Doing it for real was the goal. A goal that had proven particularly hard to reach.

The first prototypes had been assembled quickly enough. A set of vinyl strokers with hoses hooked up at various points to see how much air a cock could really puff. The first actually required the boy to pull all the way out to let air back in. Only then could he thrust to the hilt to pump it through a gauge. The figures she obtained from even the biggest of her volunteers weren't too promising. Even the most capacious of love holes had surprisingly little available volume and boosting it would be detrimental to the feeling of the lovehole. After all, boys loved them to be as tight as possible. It was the slurp as they pulled back that gave her the first breakthrough. That suction could be used to refill the lovehole as he pulled back then pumped out as he pushed in. A simple pair of one way valves at the end of the stroker and they were in business. With the new toys her lusty boys didn't have to remember to pull clean out on every thrust. A more natural fuck like that was a must to bring this idea to life. While they certainly enjoyed the lewd slurp and whoosh of the toys the flow through of the next group of prototypes left a lot to be desired. Hooking up balloons to the output valve had been a fun sight to behold but even her stallion test subject had struggled. He was the only one of her boys who had managed to pop his balloon before he came. Of course offering her body to the first boy to burst his balloon then putting on a little burlesque show for them hadn't helped with their stamina. Once she had given him the reward he had so valiantly earned. And burned off some of the lust that was distracting her she turned her thoughts to solving that problem. It was his rod slamming deep into her jet black lips that had given her the information she needed

Length alone wasn't enough to achieve the results the vixen craved but it was girth that might be her answer. After all a cock didn't merely push deep into a pussy. It was the feeling of a thick cock stretching her walls that really made her purr. And the tighter the hole the more a thick cock would stretch it. Neatly combining her need for high flow through and her boys' needs for a tight hole to ram their cocks into. Leaving the stallion snoring she had gone to work. Adding a second chamber around the tight tunnel. The stretchy inner walls of the lovehole would be free to expand while the outer more rigid vinyl couldn't stretch. The air trapped between would be forced out by every thrust. puffing through a one way valve with just the right resistance to give that perfect tight feel. As they pulled back the thinner walls would rebound. The suction of their cock pulling out filling the inner chamber drum tight ready for another hard thrust. Her new design would pump so much more than the cock piston one. And it would eliminate the slightly embarrassing pussy farts her earlier prototypes had produced. But she hadn't been able to resist the urge to build a few double pump prototypes. The extra air was too tempting to resist and those furs who weren't shy around the occasional queef might enjoy the feeling of air escaping around their cocks. Some of her testers had blushingly admitted it felt quite nice.

Finally she had her pump and she delighted in watching her helpers swelling balloons from flat to bursting, a simple modification of a nozzle to hook hoses into and they could hump toys up as well. She soon had them working around the shop, lewdly inflating a few new display toys to line the aisles. The finale of the night had come with her riding a huge twenty foot dragon as each boy humped air into its many chambers. Three hoses had been hooked up to the main chamber and her trio of biggest boys assigned to those hump pumps. The sounds of all their moans and the squeaks of the ballooning inflatable had pushed Helen to her peak. And the sight of the vixen they served writing in pleasure had them cumming into their strokers. She hadn't realised that if a boy kept humping through his orgasm his own load would find its way into the toy he was inflating and the splatter of their cum flooding her mount had Helen cumming again. The hump pump had been born and Helen spent the rest of the day finessing the design, she would have the patent in hand and the first batch on her shelves as soon as possible.

But one challenge remained. One that would take a lot of research and thought to solve. She hadn't been challenged to build a pump you humped, as fun as those were. She had been challenged to build it into a balloonie lover. And there was the problem. Her hump pump was free to fill and empty from the back. And that was fine for the puff stroke but where would the air come from to fill the pump chamber. If it was drawn from the back of the toy it would simply pull in the air it had just puffed out. It needed to come from outside the balloonie in question. She had ideas for building them into simpler balloons and toys and these would have this same problem. She needed to draw air from outside. She pencilled out a few designs but none were what she was after. The first a simple hose to another part of the toy. Effective but aesthetically it was a disaster. She briefly considered using the other holes as options for the intake. After all there were only so many breaks in a balloonie's skin. While the idea of breathing through your butt was silly it would work. At least until you tried a threesome. Then each humper pumper would be trying to draw from a hole full of your playmate's cock. The mouth had a similar problem. It wouldn't work if she was sucking on a cock. Or even worse blowing up a balloon. That was likely to be a big draw for such a mod. Humping air into your lover as she puffs it into toys. Helen briefly considered nostrils or ears but she knew a few furs who considered those tempting targets for their cocks, and the smaller the hole the more obvious the suction would be. Imagine leaning in to whisper sweet nothing in your partner's ear but she can't hear a word over the hissing of the humper pumper drawing in air.

Her saviour was something that had until the start of this been of no interest at all to the vixen. Air permeable rubber and vinyl blends. After all, what would a lover of tightly inflated things want from something that didn't hold air. But that was just what she needed: a patch of the permeable rubber, backed of course by the classic air tight stuff she so loved to squeak, and the pump would be able to suck in without leaving any unsightly holes in the balloonie's pristine body. Spreading a few such patches around her form would complicate installation but it would mean there was almost no chance of blocking them all with writhing bodies. The permeable rubber was watertight so you could play in a pool without her sinking even if some of those patches were beneath the surface. All she needed now was to order the expensive rubber and get to modding. There was only one fur that could help her test her new prototypes. That honour fell to the lucky boy whose casual wish had just stolen two weeks of her time.

Hector was his name, a tall and lanky red deer. He was shy but with a hidden needy kinkiness, maybe that was what had driven her to devote so much time to his fantasy. He'd been visiting the shop every other day for a few weeks, slowly gaining the confidence to talk to her about his desires and buy the toys he actually craved. His first purchases had been regular balloons with a mumbled justification of a big party he was setting up, then a few of the larger pool toys he claimed were for a holiday, she hadn't mentioned two of them were modded but had simply smiled as that confirmed her suspicions. Helen knew the signs of a shy fetishist and she was completely unsurprised when his next purchase contained a balloon doll. There was no pretending he had picked that out accidentally and he blushed a deep red as she slid the toy across the scanner. Ruining her eyes over the bimboesque doll in question. Willow the Wolf, the deep red rubber of her massive boobs and ass stuffed into a tiny black bikini. He blushed even further as she stroked a thumb across the glossy print of the doll's ample ass. It was true in her experience, prey species really did have a thing for their natural predators. “Just, trying it out, I couldn't pass up the chance.” He mumbled shyly and Helen smiled. “Oh I'm sure you'll love it, just be careful she's not too tight, we wouldn't want a pop before you're done, or would we?” Helen purred back. She always found this stage in her relationship with the shy fetishist style of customer amusing. She was a living balloon whose assets matched those of the lewd toys she sold, and yet they still got all blushy and embarrassed buying them, it was so very cute and she loved to tease them. Hector had blushed deeply but she could tell a pop wouldn't quite go amiss with the big stag. Her hand dipped below the counter and came up with a second Willow she dropped into his bag. “Just in case she does go bang on you. On the house.” Helen had purred to his surprise.

He had returned the next day the scent of rubber thick on his fur even under the heavy coating of soap and Helen hadn't been able to resist. “How was Willow? Nice and bouncy I hope.” She had said softly making sure no one was around to overhear. He had blushed but it was his turn to surprise her. He lifted a bag of rubber shards from his pocket and dropped them onto the glass countertop. The distinctive deep red of the shredded latex could only have come from two special balloons. He had blushed so deeply it must have been visible from space and yet he was smiling wide. Now it was Helen's turn to blush. Clearly someone had told him about her own kinky needs. She had lent forwards hungrily her boobs squishing to her counter, bringing her nose close enough to smell the scent of overstressed rubber, and male lust. “Tell me all about it!” She had panted and he had obliged. Overcoming his nervousness his story had earned him a trio more Willow dolls and sent the vixen scurrying to her back rooms for a little private time of her own.

From then on he had shared his stories of his play eagerly, talking his kinks freely, but with a trace of that blushing shyness that she loved to see. A trace that kept him in a good supply of free toys. He had tried a number of her dolls, giving her the feedback she loved to hear in all its juicy, squirting details. And had talked at length about what he would pick in a living balloonie of his own once he had the money and space for her. It wasn't hard to see Willow the wolf in those plans. That first bounce on a balloonie doll had left an indelible mark on the deer. She waited eagerly for the day he would pop a question that was sure to result in her own pop but as they had talked kinks he had admitted that he loved the idea of inflating his partner until she popped. But pumps and hoses had never quite been perfect no matter how many dolls turned to shards under them. Manual pumps and hoses took too much effort to control while tanks and electric pumps didn't allow for fine enough control. He wanted to inflate the dolls. Not ride them as they inflated of their own accord. If only there was a way for them to inflate from his thrusts. And so as he had given her such an amazing idea he just had to be the one to test it. There was simply no other choice.

And he wouldn't be free for at least two weeks. Oh well that would mean even more time to make the babes for him to enjoy. She looked over his last few orders picking out a few pointers for just what to build the lusty stag. At last it was the big day she couldn't wait to get started but it was still hours away. The day dragged on as she served a few customers. Both furs who really were planning parties and holidays, and must have been confused by the hints of lewder toys on offer, as well as her more usual clientele. But none of the shy blushy boys she so loved. Eventually the clock dragged towards the hour her store supposedly closed, and for once it actually did so. Helen hurrying the last stragglers from her shop and spinning the sign then hanging the 'no actually closed for real' sign underneath. As the shutters rattled closed she hurried back to the centre of the shop to set everything up, just a few balloons and toys to play on, a huge airbed, and her new prototypes.

She needn't have rushed, the knock she was excitedly waiting for arriving an hour later and she practically jogged to the door, pulling it open wide to find Hector standing shyly on the door step. Time to take their relationship to the next level. Even with the lewd stories he blushingly told he had never attended the shop after hours when things grew a little less restrictive so he was about to get a sight he hadn't seen before. And not just the lewder toys standing proud on the shelves. Helen's hand darted to her neck, finding the knot of her apron and tugging it open. The thick creamy fabric fell away but it was still tied tight around her waist. Revealing her huge boobs in all their glory. His eyes went wide and he gasped too shocked to do anything but admire the huge rubber globes before him. “You can touch baby, you've more than earned it.” Helen huffed, not caring that anyone on the street could see her.

The taut rubber squeaked loud as his hands landed on the huge orbs. Helen Stepped back and he followed her as if his palms had become glued there. The door swung closed with a jangle of the bell and she stepped in squishing her boobs to his chest as she locked the door behind him. As she stepped back his hands moved to frame her nipples. Lightly pinching the sensitive flesh. “I wouldn't have guessed black.” He said softly, clearly entranced by her massive boobs. Many of the dolls he had bought had been bigger, but then there was quite a difference between a balloonie and a balloon doll. The warm moving rubber was a whole different feel to what was little more than a very detailed balloon. “Having fun baby? Well get used to it there's quite a few on offer.” She purred, leading the way towards the centre of the shop. Making sure her massive boobs never slipped out of his reach. His hands fell away suddenly and he gasped as he saw the surprise she had prepared for him.

Six bikini clad balloonies stood around a huge balloon mattress that lay in the middle of a large circular pool, the high walls containing a sea of balloons and inflatables. But he had eyes only for the balloonies, and they had eyes only for him. “Time for some introductions, On the left in Angela,” Helen said and a large yellow lioness smiled and bowed low, her hands rising to bounce her boobs as she rose. With a sly smile she eased her glittery top aside just enough to reveal the deep black of her nipples. “Next is Brittany,” Helen continued. The tall shark made of a deep blue rubber licked her lips hungrily and beckoned for him to join her. He couldn’t help but wonder if those claws and teeth were as sharp as they seemed. “Charlie is the eagle in the middle.” She said as the short-stacked avian bounced her boobs at him. Her purple body shining brightly. Her large wings made her boobs bounce as she flexed them revealing the glittery finish of her feathers. “Danni is up next.” She added and a lanky but oh so busty crocodile made of black rubber slid her hands down her belly to frame the cleft between her legs, a hint of red shining through the thin fabric. “The penultimate pneumatic hottie is Ellie.” She said and a deep green bear smiled wide, stroking her hands down her hips. Unlike the other more lithe girls she was quite chunky and muscled at the same time. “Last but not least we have Willow, someone you're very well acquainted with.” She finished and Hector blushed as he ran his eyes over her familiar body. He had certainly blown away enough dolls with that body but he'd never expected to see her as a balloonie. He knew every detail of her shiny body intimately from her white tipped ears to the point of her long tail.

He walked towards the group in a daze, while each of the balloons was familiar to him he had never expected to see them moving, nor the sly grins that the sculpted rubber dolls bore turning to excited smiles. He wondered how long they had been waiting for him. “Mmm, it seems our little deer is enjoying the view, how about we give them something to look at too?” Helen purred in his ear as she slid her fingers into the waistband of his pants. With a hard tug she slid them down and his cock sprang free, the thick member standing proud and ready, almost pulsing with need. “Well that certainly explains how you manage to bust the dolls so easily.” Helen cooed as the balloonies giggled and traded whispered words. “So cutie who is going to ride this monster first.” Helen teased her hand stroking down the soft fluff of his belly to lightly grasp the base of his thick pole. From his expression of shocked delight she knew he simply couldn't choose. They would have to think up another method.

Helen paused for a second then smiled. Time to show off another invention the last few weeks had led to. She pushed him forwards into the girls. “Hold onto this cutie for me I've got to grab some things.” she called striding towards her workshop. Hector yelped as he was pushed into a rainbow of eager balloon breasts, their bodies squeaking against him on all sides. Helen watched happily as he was drowned in latex cleavage but she had more pressing matters to attend to and she strode quickly away, the faster she went the sooner she would be back. She burst into her workshop and quickly dragged a few newer projects aside until she found her target, a box of what looked to be fairly simple three foot beach balls. The same she ordered in bulk every week. Only the fact both ends bore a nozzle hinted at the special feature. Dropping a set of short hoses and a bag of six foot balloons into the box she had everything she would need. She lugged the box back towards the centre of the shop, the sounds of squeaking latex and sultry giggles growing louder with every step.

She was surprised at what she saw, Hector had recovered from his surprise and rather taken control. Willow was pressed to his chest while his hands were groping the butts of Charlie and Ellie, his fingers sinking deep into the rounded cheeks as he pulled them into her back. His face was buried in the wolf's ample boobs. The trio of remaining balloons were pressing against him, Angela behind him while Brittany and Danni flanked him on either side. His hands and lips were busy trying to please them all, groping and squeaking over the soft rubber of the eager balloons. The thump of the box as she dropped it made them all jump. He blushed at being caught that way, as if this hadn't been the plan all along when she invited him. A touch of his shyness coming back. “OK, each take a ball and start puffing, not too tight and only use the white nozzle.” Helen called tossing a beach ball to each girl in turn. They sank back onto the walls of the pool and started to puff into the toys. Swelling them fast as Hector watched in awe

“Never seen a balloonie puff something up before?” She asked the clearly impressed stag and he shook his head. “It's quite a sight, won't be long until they're full.” she added. True to her words the balls were tight in only a minute, the thump and squeak of vinyl ringing out as they capped the balls off and dropped them to the floor. It was the work of a moment to ease a balloon over one end of the hoses and she passed one to each girl. “Plug that into the black nozzle. And wait for the word go.” She told them then turned to Hector looking on with an expression of slightly confused excitement, he didn't know what she was up to but was clearly excited to see the results. “A little demonstration of what your idea resulted in. These are pump balls. When you bounce on them they puff out of the second nozzle. So to decide which girl gets to go first we're going to have a little race. The order you bounce on them will be the order they pop their balloons in. the fastest pop gets the first ride.” She cooed, the vixen almost as excited as he was. She had big plans for these balls. Starting with sticking a dildo in place of the nozzle but that would have to wait until the batch of custom dildos arrived.

“Take your marks.” Helen called and they watched as the girls chose their positions. Danni and Brittany decide to sit on their balls, simple but powerful. Danni hoped to show off her ass while Brittany was relying on the tease of her boobs bouncing. Ellie was leaning forwards pressing her breasts into her ball. While Angela had fully flopped onto it, her ass pointed at the fur she aimed to tease Charlie had decided on a unique strategy, planting her ass on the floor her ball was between her knees. She intended to put her powerful thighs through a workout. Willow seemed uncertain on what pose to choose. Perhaps the fact his eyes strayed only briefly from her ample curves was making her nervous. She eventually settled on sitting on the ball. Following the lead of Danni and Brittany

“Ready, Set, GO.” Helen called and all six balloonies bounced high as one. One of the few disadvantages of their air filled forms was a lack of weight, they would have to make up for it with enthusiasm. Only by bouncing high and slamming down hard could they match the force a regular fur could achieve with a light bounce and they would need to go all out to make their balloons pop. Six large squeaks forced six loud hisses down the hoses and the balloons started to swell, each one matching the balloonie whose efforts swelled them out. Hector didn't know where to look. He had walked here today expecting to talk to Helen, and now he found himself in a scene that not even his wildest dreams would have dared imagine. His eyes whipped from side to side, watching as asses and breasts squished into the beach balls with loud squeaks. His cock jumped as he looked from Ellie's breasts squishing and Angela's bouncing to Danni and Brittany bouncing their huge bubble butts on the balls. Charlie's powerful thighs had her ball squealing as she took the lead, her pose perfect to squish the ball. Angela on the other hand had picked a great pose to tease but she was trailing. Ellie's breast squish wasn't far ahead. Only the hard booty bounces of Brittany and Danni could hope to best the eagle and they were bouncing hard, booties rising and falling with loud boings to try to keep up. He looked to willow but to his surprise she was behind by even more than Angela despite her potent pose. Her eyes met his and she winked, clearly the wolf had a plan, giving up the first ride for something more desirable.

Helen smiled as she watched him desperately trying to see every bounce and squeak. She could afford to savour each one in turn, after all she knew every bounce was being recorded. She sat back to watch the show, it wouldn't be long. As the balloon swelled they boinged and squeaked louder, each girl pulling the balloons against them to make the latex squeal, but they knew not to cheat, a squeeze pop was more likely to get them popped by the pink vixen than the cock they so desired. But that was really the only chance they had to best Charlie. Her balloon was already creaking while the others had only just reached the rated size. A few more powerful squeezes, crushing the ball between her knees and the balloon blew with a soft boom. The safe pop rubber tumbled lightly to the ground. Things were going to get loud soon enough, no need to make his ears sting before they really started. Danni's balloon burst mere moments before Brittany's succumbed to her ample ass, a real photo finish. Ellie's breast press took a few moments more to add another bang to the count. It took nearly a minute longer for Angela's unique pose to produce a pop, but watching her breasts bounce really had Hector huffing. She would have done much better with his cock between those huge boobs. They looked over at Willow and the big wolf smiled. Her hips suddenly starting to move, her long, deep bounces sank her rump further into the ball than even Charlie's thigh squeeze had managed, the balloon at the end of the short hose surging out with a squeal of stressed rubber only to blow apart only a few seconds later. The buff wolf smiled, revealing she could have won with ease, but instead had chosen to be the last girl he would ride.

“Well looks like we've found out the order, Time for you to get humping lover boy, remember the harder you bounce the faster they balloon, but no holding back I want to see that cock of yours make these toys pop.” Helen huffed revealing her oh so kinky side. Stories were nice, but for her very valued customers she needed more, she needed to see them in action. He hesitated for a moment then climbed over the high wall of the pool, the warm rubber of the balloons that filled it squeaking around him. He turned at a squeak and saw Charlie climb after him, she had won the first round and he couldn't help but be excited. She was a goddess of an eagle, her sculpted rubber form implied powerful muscles, and yet her huge ass and even bigger boobs had curves that made him huff. “How do you want me baby?” She trilled licking her beak with a squeak. “Let's start with a classic, missionary.” He replied, from his experience with the doll versions, her wide wings were perfect to brace against the bed, pushing her chest up as he hammered at her nethers. He hoped a living balloon would push up even more eagerly. He watched her lie on the bed and jumped up eagerly after her, the inflatable mattress rocking beneath him as he crawled forwards. He wanted her bad, but despite his need he knew the importance of foreplay. Gently spreading her knees he pressed his muzzle between her legs, his broad tongue pushing her bikini aside then playing over the valley between them. Her soft trill of pleasure made his rod bounce in sympathy. The latex felt different under his tongue, but he couldn't tell if that was because she was a balloonie, rather than the balloon dolls he had played with before, or because of her intense wetness that slathered his muzzle and chin. What he did know was her lips were much puffier, perhaps part of the changes Helen had applied. And he had to fight to plunge his tongue into her dewy flower. The tip sought out the amazing nectar within and made her squirm as it plunged deep.

Locking lips with her pussy he blew softly, something he had always delighted in doing with the dolls, the valve within letting his air flood through to swell her bigger. But with a living balloon it was on a whole other level. Charlie's squawk of surprise gave way to a long deep moan, her powerful thighs that had so easily pumped the beach ball closing on his head and squeezing tight, The rough texture made him hope she didn’t intend to use her claws, that though was quite an incentive to make her moan. With soft squeaky rubber all around him he blew again, even harder. His hands on her hips feeling them swell out wider and curvier. The sound of her moan echoing through her hollow body made him huff as her juices poured over his tongue. It took quite a bit of pressure to force her legs open before he could push up and crawl forwards once more. His soft puffs had swelled her breasts out at least an inch and her bikini had sunk into the soft latex. He was t empted to free her huge bouncy boobs but the effect was too hot. Instead he groped them then lay atop her, squishing her breasts against his chest as he pressed his lips to her beak. He was focused on Charlie but it was hard to miss the appreciative huffs and soft moans all around the pool. The others were clearly enjoying the passionate show.

He humped lightly trying to find his mark then gasped as his tip kissed her plump lips. The wetness around his tip was unlike anything he had felt before as he slowly eased his way into her. She was tight, way tighter than the doll he had tried before. Even when he had puffed it right to the edge of popping. And yet her lips yielded to his thrust, letting him sink into the silken vice of her pussy with a long squeak of wet rubber. He drove into her feeling her swell beneath him, driving to the hilt in one long thrust. The light slap of his balls against her made them both groan. Hector held there for a few seconds savouring the feeling of her pussy before pulling back slowly to the tip. The suction around his cock trying to drag him back in. He had to push up and brace his palms on her wings, holding her down to drag his rod from the vice tight tunnel. The soft hiss of air over his tip as he broke the seal proved too much and he surrendered to her body's desire diving back into her with a lusty moan. The feeling of her boobs surging out against his chest made him gasp and he pushed up as he eased his hips back once more.

Driving in slowly he watched her swell, her boobs gaining two cup sizes as her ass pushed her up towards him. Her top pulling tighter, sinking deep into the ballooning boobs, another buck and the thin straps were strained to their limits. Hector smiled and bounced with shallow thrusts, none greater than a single inch. Despite the shallow humping, each one drew a soft hiss from her pussy and swelled her breasts even bigger. With a loud snap her overstretched bra gave way her huge boobs spilling out as she moaned loud. With a loud caw she pushed back with her wings, forcing her chest up and her bouncing breasts squished to his face, her arms wrapping around his back and pulling him into the deepening valley between her expanding breasts. He could feel her pussy going wild on his cock. Each clench pushed more air into her body, almost as much as his rapidly deepening thrusts were pumping into her.

Hector was in heaven, each thrust driving more air into his partner the squeaks and hisses and boings of a hard pump hump making him shudder and moan, and from her lusty gasps and trills Charlie was fast nearing her own peak. He could feel her body growing tighter under him but he was too lust drunk to notice. Helen on the other hand was biting her lip. She hadn't expected the eagle to swell so fast. She had overshot her target, each thrust was pushing more air than planned, but that wasn't all her fault, he should have told her he was packing such an impressive plunger. Forgetting to factor in the effect of the girl's own muscles was her fault though. She hadn't considered the fact that each clench and squeeze she gave would also pump more air. But then that was why she ran these tests, and why she had prepared multiple babes for him to try out. She watched as Charlie ballooned under him, her body easily taking his hard bouncy thrusts, but not for long. Soon she was creaking, but her loud cries of delight masked them, simply urging him to bounce faster. The first Hector knew of how close she was was the scream as her orgasm hit, between his long, thick pole pumping her pussy and her dangerously tight body she hadn't been able to resist. Most balloonies tried not to cum before their partner but she was helpless under him.

There was no second warning, Charlie's orgasmic moan cut off by the titanic explosion as her body came apart, the two boobs around his head turning from huge four foot spheres of taut latex to clouds of confetti, the massive ass that had bounced him so high vanishing into shredded latex. Her body came apart in a moment, seeming to vanish beneath him. His hands had been braced against her wings and their sudden absence made him slip. With a yelp he dropped to the bed, landing hard with a squeak amid purple snow. Only her limbs and wings had left any recognisable shards, but even they looked as if they had been pushed through a shredder. Hector pushed up, ears ringing, the surprised expression on his face giving way to a smile as his cock basted the bed with pre. It had come earlier than he expected but he had fucked air into a balloonie until they blew. And there were still five more to play with. He eased some of the shards of Charlie's pussy from his cock, it had fared better than most of her and now looked like a lewd burst condom on his thick pole. He hoped she wouldn't take too long to reform but he had other balloons to focus on for now.

“Whoops, looks like the queen of the skies couldn't take a few bucks from our buck. I'm up next.” Danni called the tall croc stepping towards the pool only to see Brittany already scrambling over the side of the pool. “Hey- I called dibs” “No, I'm up next.” the shark huffed as Danni jumped after her. “Girls, Girls, you're both up next.” Helen called and saw Hector gulp. Handling two needy balloonies might prove to be a bit much for him, and the croc and shark were the biggest and buffest of the group. But he relished the chance to try. Brittany reached the bed first jumping up and flopping down onto her back with a loud squeak, only to let out a loud ‘oof’ as Danni threw herself on top of the shark, pinning her down breast to breast. Hector huffed happily as they made out, they both wanted his cock first but they were here to tease him above all and they knew it. Their bodies squeaking together drove him wild and he almost jumped on the balloon pile but he needed to calm down a touch, no sense popping on the first thrust. He was a true gentleman and knew to never skip foreplay even for a threesome.

He straddled brittany's finned tail and gently lifted Danni's long tail high to expose their big bubble butts, his left hand squeezing Danni's while the right groped Brittany's cheeks, he did his best to keep things fair matching grope for grope as both bouncy babes moaned for him. The difference in texture was amazing. Danni’s rougher scaled booty vs Brittany's smoother almost velvety shark rump. Leaning in he nuzzled into their pussies, the plump lips pressed together, squeaking as they moved. Hands stroking over both booties he hooked their panties with his thumbs easing them aside then pressed his lips to theirs trying not to favour either of the girls. His tongue squeaked over the shiny latex with twin squeaks. The vibrations of each balloonie make the other moan and gasp. He lapped over their latex lips with a loud squeak then pushed it between them. To his surprise their juices had two distinct flavours. Danni's juices had a hint of liquorice, an acquired taste perhaps but one he liked. Brittany's flavour was predictably blueberry as they ground their bodies together and his tongue stroked wildly over their pussies their juices flowed freely dripping down Brittany's rump to pool lewdly over her tailhole. The sight made him huff, he was going to have to tap that ass.

Pulling back he eased his thumbs into each balloonies pussy, smearing his hands with their sweetness. With a smile he guided his thumbs to the other girl's tailhole. Smearing Brittany's blueberry flavour wetness over Danni's ass. The liquorice sweetness was already drooling over Brittany's backdoor but she moaned loudly as he pressed his thumb into her rump. “I've only got one tongue, girls, so who wants to get their ass eaten first? Whoever can resist the longest gets my cock first.” He purred. It should have been an easy choice, but with his thumbs teasing their rumps as his fingers worked their magic on their drooling pussies spreading them to let his tongue squeak over their sensitive lips they soon found it hard to resist, pleasure later was hard to wait for when the pleasure right now was sure to be pure ecstasy.

Danni squirmed as his thumb pressed into her ass and fingers drove into her pussy again and again with lewd slurps and pops. She had to resist, she wanted his cock bad, but it was all too much. “Oh oh fuck eat me out.” The big crocodile begged, blushing a deep crimson through her black rubber. Brittany smiled in triumph under her but her expression turned to jealousy as the croc's mouth opened in a lusty moan, her eyes crossing with pleasure as Hector focused wholly on her. His tongue slamming into her tailhole and fingers groping her huge cheeks dangerously tight. The squeaks of wet latex ringing through her body served to tease Brittany even more. He was far from done and pulled back for a moment to huff deeply. Pressing his lips to her booty once more he blew hard. The loud fwooosh was completely inaudible under Danni's scream of pleasure. He teased her for nearly a minute before turning his attention on the shark. She had been helplessly trapped under her rival, watching as each move the deer made made her judder and jump. The feeling of his tongue on her own ass made her squeal in excitement. The rough tongue fucking rocking her body, then he blew hard and it was Danni's turn to look on jealously as the shark writhed under her. She could see her swell when he blew and jump as he plunged his tongue deep.

Hector wrapped his palms under the croc’s big tail and lifted her high. The sudden press of his tongue to her backdoor made Danni jump and She looked down on Brittany as her look of disappointment vanished as she felt his cock sliding along her tail. His hands lifted Danni's hips up a little higher, his tongue playing over her ass and pussy as he slowly slid his rod towards his target, the massive puddle of need that coated Brittany's backdoor. He sank into her ass with a loud squeak and even though her lust Danni watched in awe as she ballooned. “Damn she's so tight you're pumping her huge.” She panted as the shark's already large breasts puffed out against hers. He bounced a few more times then pulled back, pressing Danni down onto Brittany until their pussies were grinding together with loud wet squeaks. She felt his hands on her ass and moaned loud as his cock found its mark, sliding into her ass with surprising ease despite the tightness. Danni howled as she felt it force air into her body. Swelling her in Brittany's arms, the shark pulled her close, making out with her as he bounced lightly in her booty. The wet squeaks his cock wrung from her asshole making them both shudder.

Every few thrusts he switched from one balloonie to another. His long cock wringing loud squeaks and deep hisses from their bodies as well as their lusty moans. He did his best to keep them roughly the same size, even with the intense pleasure he felt he was doing a good job there. But the real test was about to begin. Pulling his cock from Danni's ass he pressed between their lips. The feeling of two soaking wet pussies around his shaft made him moan loud and he sank into the pair, reaching around Danni to grope the quartet of balloon breasts on offer. They humped together, squishing his cock between them as he humped gently. Just that pressure on their pussies was enough to swell them slightly but the two big balloons knew that wouldn't be enough to tease. They took it in turns to blow into their make out and the feeling of the bodies swelling under, and around him made the big deer huff.

He huffed with need and pulled back, aiming up slightly he felt Danni's lips part around his tip. She gasped as he pushed in with a loud, wet, squeak and a loud whoosh, he felt her ass swell against his hips and her boobs ballooned but she knew he wanted Brittany swelling too and as she ballooned she puffed an equal amount of air into the shark under her. With a lusty moan Hector pulled his hips back and aimed down to sink into Brittany's waiting pussy. Now it was the sharks time to swell but she too blew into the kiss, he drove to the hilt then pulled back fast, he felt her roll her hips to help him change target once more. It was surprising how quickly they had figured out what he wanted but the results were exactly what he hoped. Each thrust he changed the balloonie he was pushing into. And the hole he was humping, savouring the different tightnesses of their pussies and tailholes. The squeaks and whooshes of the pump fuck making his toes curl.

Each thrust swelled both balloonies bigger and tighter. Hector could feel his own peak was approaching fast but somehow he knew their limits would arrive first. He could try and draw things out but he had three more eager balloons to play with. Why not give them what they craved? They were so big and tight, ready to pop at any moment. He drew back slipping from Danni's lips with a squeak, both balloons were right on the edge of popping, he had worried that just pulling out might have blown her to bits. With a huff he guided his tip to the diamond of their pussies and sank blindly forwards. Chance would choose where he ended up; shark or crocodile the result would be the same. His hips bucked to drive him deep into the lewd valley with a squeak, knowing full well that neither could take his cock. With a titanic double boom they exploded beneath him. Their powerful bodies shattering into black and blue confetti. He was never sure who he had hilted in, or if he had at all, maybe just the pressure of his cock had been enough to push them over the edge. It seemed only fair that such a pop should match the pop they had managed in the race.

He pushed up panting hard and looked over at Ellie. The big bear was huffing and panting madly, the show had clearly proved too much for her. He pulled her up onto the bed and pushed her down onto her back, his hands stroking over her shiny latex to cup her huge breasts. “I know where I want to be, only try not to crush me like you did to that ball.” He teased as he played with her ample assets. Each touch made her gasp and moan, and to his surprise swell slightly. Helen laughed as he squeezed her breasts tight. One hand sinking into each massive orb. “Well I couldn't resist, not with boobs like hers.” She called out as he groped her breasts bigger. Much to the bear's vocal delight. He straddled her belly and pushed his cock between the bear's massive bouncy balloons. As long as he was her huge tits swallowed it with ease.

He had always enjoyed the feeling of rubber balloons around his cock. He was no stranger to balloon titfucks, but those tits had belonged to simple dolls. A balloonie was on another level. His hands squeezed them to his rod, the warmth all around his shaft making him huff. His hips started to buck and he bounced lightly on her belly. As his ass sank into her her already massive boobs ballooned even larger. Shrinking slightly as he lifted off. With every bounce he slid a little deeper into her cleavage, smearing it with the slick juices of his previous playthings. Each buck of his hips making her rubber breasts squeal around his cock. Her breasts were just too sexy. He couldn't keep his hands off them. It didn't help that every squeeze he gave to Ellie's massive breasts only ballooned the bear’s big boobs even bigger. Already it looked like she had a pair of tight thirty six inch balloons on her chest and they were only getting bigger. He wondered if he could go all the way and pop her just from that, but it didn't seem fair to ignore her pussy. Not with the needy gasps and pants every squeak of his cock on her skin forced from her lips. He grabbed her hands and pressed them to her boobs, leaning back he kept bucking into them but one hand stroked down her belly. With a squeak and a happy moan from the bear it slid between her legs.

He pressed his hand into the sopping wetness between her powerful legs then drove his fingers into her tight lower lips. The crushing clench that followed her loud moan showed just how horny his toys were getting. She needed more and bounced her boobs on his rod fast, squishing them together as she lifted them then slammed them down into his crotch. Her fingers were pressed deep into her thin rubber, almost as deep as he was sinking his into her pussy. He had made gentle love to her breasts. Ellie's efforts on the other hand could more accurately be described as a brutal fucking. If she had been a regular fur she may well have ended up bruising his legs and belly with the force she was pumping her boobs up and down against him. But as they were balloons it simply made her ample breasts squish beautifully. He couldn't help but buck into her, urging her on with expert strokes of his fingers. Hector watched in a mesmerised trance as her breasts bounced and stroked his cock. The bear was no stranger to pleasuring a guy and she changed her tack every dozen or so bounces of her huge breasts. At first lifting and dropping them together. Then one rose while the other fell. Then she spread them to clap them on his cock as they bounced. Each new tactic pushed new feelings into his rod, and she made sure to use every inch of his impressive length.

With such an amazing distraction, and a big bear to make moan, it took him a while to notice something was missing. His comparatively gentle handling has swelled her breasts nicely. Ellie was pressing her hands into her breasts as if she was kneading dough, but there was no sign of swelling. “Shouldn't your boobs be bigger by now?” He huffed to her and she frowned. The big bear was equally as confused as he was by the lack of ballooning of her chest. “Oh that's a safety thing.” Helen said, reaching out to squeeze her breasts hard making Ellie moan as they gained a cup size. “You can't let girls like this slut balloon their own bodies, if I had left that in she'd have groped herself to a pop long before you arrived.” Helen continued squeezing Ellie's breasts again and huffing as they ballooned. Hector couldn't help but smile. It wasn't just Ellie looking towards seeing them blow. Noticing his attention Helen blushed then smiled. “If you want these to blow you'll have to do it yourself.” Helen said, giving the huge breasts one last squeeze then stepping back.

Hector nodded he was more than willing to put in the work to make her blow. But it would need a change of position. And since he was moving it would only be fair to try out her pussy, the way it had clenched on his fingers with every stroke had him eager to feel those clenches on his cock. He pushed up, lifting from her belly to slide back to kneel behind her. Her breasts had inflated the most, almost doubling in size, but the rest of her had filled out a little too. The puffed up lips of her drooling pussy called to him and he slowly guided his tip to them. The green latex spread as he pushed in, feeling like a silk covered vice. He was lucky she was so wet. A pussy this tight wouldn't have been able to take a cock like his. Even so, pushing in wasn't easy. And it got even harder as he grabbed her ankles and lifted her legs high. He pumped down into her squishing the bloated bear into a hard mating press. The squeak of his cock driving deeper than ever into her pussy drowned out the soft whoosh that swelled her even bigger.

The drawn out foreplay had already swelled Ellie pretty tight but he couldn't resist burying his face between the bear’s massive boobs. The pressure of his muzzle between them was enough to make them swell once more. Her hands rose to cup her breasts, while the pressure of her fingers couldn't trigger the swelling. The pressure of his face could. Squeezing her ballooning boobs to his muzzle only made them grow bigger and bigger much to her delight. He knew from the growing creaks she didn't have long. His orgasm might be out of reach, but hers was in sight. Hector's hips slammed down into the bear hard and fast, making her pussy clench and whoosh around his cock. Each thrust pushed her towards both her peak and her pop. The mating press let him plunge deeper than ever. He could feel the internal valve at the back of her pussy and pushed even harder, he wanted to push through it and he didn't have long. A final deep plunge and it opened before him. His tip pushed through into the inside of her hollow body. With a howl of bliss and squeal of rubber she came on his cock. Her breasts surging out to smother him as her overblown body gave in to the pressure within. Her lusty roars of delight ended in a boom that left his head ringing, maybe having his face between her huge boobs as they blew hadn't been the best idea.

He dropped to the bed through a cloud of green rubber shards, panting and huffing as he caught his breath. His cock still aching with need. But by putting on such a show he had insured he wouldn't be getting any breaks. Almost at once a new balloonie landed before him and he found Angela's literal bubble butt bouncing just inches from his nose. Her long tail swayed happily. “My Turn baby, pump me until I pop.” She begged needily, Being so late in the line up had clearly had an effect. Watching four lusty balloon girls booming had driven the lioness wild for her own fuck and pop. She wanted to blow and wouldn't take no for an answer. “I'm gonna need a bit to recover.” Hector panted but that wasn't part of Angela's plan. “I'll let you fuck me in the ass.” She huffed needily, her hands grabbing her plush cheeks and spreading them. That sight managed the sort of rejuvenation that normally took a two hour nap. With a needy groan he pushed up and lunged onto the lioness' back.

She squished under him as he lay atop her, his hands hugging around her to grope her breasts. He humped into her and felt his tip push into her pussy. Angela tutted and reached between her legs, pushing him back from her lips and guiding him up to a tighter, lewder hole. With a groan of need the buck sank into her rump, taking the lioness backdoor with a wild need. The tightness all around his rod whooshed and squeaked with every thrust, her vice tight backdoor pumping more air than her pussy would have. Already her breasts were ballooning in his hands, much to the buck's delight. She hadn't expected her tease to land so effectively, he was full in rut as he rammed her ass with deep fast thrusts. Pushing his long cock to the hilt before her bouncy booty lifted him back to the tip. And each thrust simply made her booty bouncier under him. Two desires warred within him: one his need to cum, urging him to hold back, not to burst the balloon under him. The other, in a louder and more excited voice, wanted only one thing. To pound the predator's tight ass, until she gave in.

There really was no choice at all. Angela's lusty yowls as his bucks sped up and he thrust into her deeper and harder showed he had made the right choice. The thump and boing of his hips on her ballooning ass drove him wild and he lent in, pressing his muzzle to her ear. “Gonna fuck you until you pop.” He panted and yelped as her ass clenched tight. “Go on my big buck fuck me until I can't take any more. ” Angela panted back. The lioness’ reply had exactly the effect on him she had hoped for and he started to slam down into her. Bouncing so high on the inflatable mattress that she was lifted after him. Only for him to come crashing back down, squishing her to the vinyl and making her already overblown body bulge.

Helen pulled Willow close her hands idly exploring the ample ass of the big wolf. It wasn't hard to see how much the show was affecting the vixen, it wasn't much better for the wolf herself. Knowing that everything was going according to Helen's plan wasn't helping her bear watching him pound Angela's tight ass. The boing and squeak of every thrust echoing off the high ceilings. “Just let him wear himself out a bit more. Angela's not going to last much longer.” Helen whispered her hands stroking over Willow's powerful thighs. She could feel the wolf trembling with need. Each moan from Angela makes her grind her thighs together with soft squeaks. Hector was oblivious to their quiet planning, all his attention was focused on the lioness whose ass he was balls deep in. Each boing and thump of his hips bucking was joined by a soft whoosh. The sound was music to their ears as both he and Angela were desperate for what it would bring.

Watching the once lithe lioness round with every pump of his cock into her ballooning ass was driving him wild. His hands stroked up her thick thighs and over her bloated belly to grope her massive boobs. They had grown so large they were pushing her arms outwards and her nipples brushed the bed as the huge orbs bounced and jiggled. Her head hung low as she took his hard ass fucking and with a sudden ecstatic moan she clenched down hard on his cock. “Oh Fuck I'm going see though.” She panted lust dripping from every word. Clearly seeing his cock pumping her through her own overblown boobs had a powerful effect on the soon to blow balloonie. He knew he didn't have long and bounced wildly on her but he wanted even more. Hector reached out, grabbing her wrists and pulling them up and behind her, now his entire weight was being supported by her massive boobs and they squeaked and squealed as he bounce fucked her bigger and bigger by the second. He might not be getting an orgasm out of this but she was. Angela roared passionately as she came, the rough handling pushing her over the edge just before the humper pumper pushed her body over its limit. Her juices were spraying over his balls when she gave in with a titanic boom at the bottom of a hard bounce. Hector dropped to the bed with a thump and lay there panting as he caught his breath.

Rolling over he looked up at the final balloonie, his first doll brought to life and panting hard at the sight of the cock she was about to ride. The air filled mattress rocked under him as she Jumped up and crawled towards him. Her fingers easing Angela's shredded booty off his cock and dropping her among the shards that surrounded him. Her hand pressed to his chest held him down gently as she straddled him, her red rubber body shining bright as she manoeuvred into position “I'll take charge baby, you don't want me to pop too soon like the others.” She said softly and he nodded letting her take the more dominant role this time. He had to admit it did make his heart race to be under the big buff wolf. He slid his hands to her thighs, sinking his fingers into the soft rubber. “I'm ready.” He huffed and she sank slowly onto his cock. His tip parting her ruby lips with a squeak and the faintest whoosh.

Hector did his best not to hump up into her but it was a struggle. The girl of his dreams was bouncing on his cock. And each squeaky bounce swelled her even bigger above him just like she ballooned in his kinkiest dreams. Willow smiled down at him as she bounced then lent in pressing her boobs to his face. The giant red rubber orbs squishing to his muzzle “Helen told me all about your dolls baby. Bet you've never had one this way.” She purred and he moaned happily. She was tight, he'd always taken the toys in dominant positions, but he was starting to see the appeal of letting her have his way with him instead. He gently pressed his hands to her hips sinking them into her rubber skin to feel it swell and stretch. The soft hisses that underlay the lewd slurps and shlicks of her slow ride making him huff happily. Part of him wanted her to go faster and deeper, to swell out above him more and more with every bounce of her amazing ass. But another part knew this was his last chance to cum. He needed her to outlast him. Even if it meant taking things slow.

Watching the five balloons before he burst had shown Willow what she had to do, she wouldn't make it if she simply bounced on his cock. Her body would give in before he popped his cork, she would need to excite him some other way and it was Ellie that had shown her how. Her hands rose to grope her boobs, squeaking the thick rubber loud as she pressed them to his face. His muzzle sinking deep into her inflatable cleavage. His cock throbbing with every squeak revealing her plan was working. That the pressure of his face on her boobs was helping to swell them added a little extra kick to an already amazing ride. As his head vanished between her boobs Willow realised she had missed the second lesson she should have taken from Ellie's boob play session. The first was that Hector loved to be smothered by huge rubber boobs. The second was that smothering him with those boobs would make them swell fast. She was starting to creak and he was far from his own pop.

She found she couldn't slow her bounces, if the choice was popping or slowing there was only one thing she could do, her moans grew louder and louder as she neared her limits, her bright red rubber fading to a transparent pink. She was about to blow when Helen intervened, pressing a simple balloon into her hand. She stretched it quickly in her paws racing her own pop then pressing it to her lips. A deep breath swelled it out just in time, her body shrinking just enough to take the next bounce puff. Helen smiled, that had been close but she couldn't just let her have it so easy. She lent in her lips as close to his ears as she could get with the titanic boobs either side of his head. “No need to hold back any more baby, fuck her hard.” She purred to the deer.

Willow moaned as those words landed in his lust-addled brain and he thrust up into her. Only a deep puff into the balloon saved her from exploding. The swell and shrink of her boobs on his face made him huff and buck harder. The squeak and whoosh of their play grew louder as he hammered up into her with lust wracked moans. Willow wasn't one to give up her role so easily and as he started to thrust she bounced harder and deeper, puffing out as she sank onto his cock. It would have been easy to blow and the moans he made as her boobs swelled on his face tempted her to go bigger even as she pulled him close to smother him. The balloon she was puffing out groaned as she forced it to swell faster and faster to take the air his thick cock was pushing into her dangerously overinflated body.

Helen settled back to watch the show, Willow's hard fast bounces vs Hectors deep thrusts. The squeaks and moans filled her shop as she slid her hand between her legs. They were really going at it but she couldn't help but notice the balloon Willow was puffing up, the one that was all that was keeping the wolf from popping, was getting pretty tight. Neither seemed to notice and she doubted they would care, they were right on the edge of their own pops. Hector's hands explored Willow's body with loud squeaks as he pulled her down onto his cock again and again, her drum tight rubber body letting out hollow thumps as she landed that were counterpointed by loud squeaks as her vice tight and soaking wet pussy slid up his cock. He grabbed her hips firmly and started to pump her fast the whoosh of the humper pumper just audible between their moans and the squeak and slap of their bodies grinding together. “Oh fuck Willow I'm close.” He panted to her and earned a lusty moan back from the big wolf. “Go on! Fill me with your cum!” She begged and he slammed her down deeper than ever her lusty moan whooshing into the balloon.

It had fought valiantly against her hard puffs for as long as it could bear but even the premium rubber had a limit. The huge balloon exploded with an enormous kaboom. Luckily for Hector Willow's breasts pressed tight to his head were the perfect ear protection, even so it was loud and he could feel the vibrations of the shockwave ringing through the wolf in his arms. It was that that finally pushed him over the edge and he pulled back from between her breasts to look her in the eyes as he came. “Here it comes.” He gasped as he exploded within her. His cock throbbing hard as he unloaded into her clenching pussy. Watching her head fall back as she howled her own pleasure loud. She was so big, the already large wolf had more than doubled in size. The deep crimson of her body had become a see through pink as she grew bigger than her body could handle. His heavy long awaited load would see to that the added filling pushing her beyond her limits. Willow's lusty moans turned into a gasp as she felt her body give in. “Oh baby I'm gonna-” She panted but never finished the sentence. Her body exploded with another huge boom.

As shards of red rubber rained down all around him Hector slumped back onto the bed. He lay still for a few seconds, enough to worry Helen and she moved in fast to see if he was OK, Only to freeze half way there as soft snores filled the air. He was fine, just worn out by the power of his orgasm. It was no surprise, five of her air filled helpers had accidentally edged him to perfection. Then Willow had popped his cork and it had popped her in turn. She smiled and walked over to a cupboard pulling out a thin blanket. She laid it over the sleeping deer. Gathering the more accessible shards she headed for her workshop. She would need to note down the results of the first test and get Willow into a jar of quick patch gel, he had more than earned her. She stopped off quickly at the security booth, making sure the recordings were saved, the store's many cameras would have caught every last moment.

Maybe a pump that could push a thirty six inch balloon from flat to fragments in only a few dozen thrusts wasn't the best thing to put in your lover. Her lust for fast inflation had led her a touch astray. She would have to dial back the output volume a touch for the final version. She hadn't thought to account for the added pressure a fur's weight would put on his partner, and the pump within her. She reached for some red rubber sheets and started to unroll it. If she worked fast she should have just enough time to make a controllable humper pump, being able to fine tune the speed of inflation on the fly would make it so much more useful. Willow and Hector would be sure to help her test it out and this time she might take him all the way herself. She would leave the others with the overactive pumps for now, there were plenty of her regulars who would love to meet them. She shook her head to dispel the lewd images and turned back to her work. She would need a distraction to keep herself from waking the big buck and taking a ride of her own.
