“This sure looks like the right place.”
Kitsune Sumara, a bright yellow, nearly golden vixen with a perfect complement of cream underbelly fur, all wrapped up in a lime green half-kimono, was on her way to earn a little extra pocket cash, and perhaps have a little fun doing it. Times were tough for everyone, after all, and when Kit had spotted an ad in the local paper asking for resident females to test out a new sort of fertility product, she figured she had nothing to lose.
Still, skepticism was clouding her mind as she walked up the small stoop in front of 742 Wicker Drive, a small community center building with rooms often available for public use and classes. Being a Saturday, most of the rooms were empty, and as Kit opened the front doors to take a look inside, she was beginning to wonder if the entire place might be deserted. It wasn’t unlike an elementary school; a large, spacious hallway with tall ceilings, and doors dotted the walls on either side every thirty or forty feet. “Room 305…third floor. And there’s no elevator, naturally.” Kit was a little dismayed, but she watched the walls until she saw a sign for the stairs, and started her trek up to the third floor. This was starting to seem like more and more of a bum deal to her with each step she took…
“Well now, there’s a sight for sore eyes!”
…Until she saw a very close friend of hers standing at the top of the stairs. A long, flowing red dress, cut up the leg almost all the way to the hip adorned her figure, held up only by the large, pert bosom that rested upon her chest. Thigh-high leg sleeves of scarlet and gold added sensuality to the look, and clung tightly to legs that could kill a man, flowing up into wide, curvy hips, and slimming right back down into a toned, tiny waist. For the cherry on top to bring it all together, she wore sleeves upon her arms as well, matching of scarlet, with gold bangles hanging around each wrist. Under all of the bright, scarlet red and gold, dark, onyx flesh shined in the dim lights of the building, with white armor plates providing essential protection to her tail tip and the bridge of her muzzle, with a sharp black horn piercing through her mask.
She was no other than Angela, the cyber dragon.
“Angela!” Kit cried out joyously, her grim, bleak expression turning to a bright, beaming smile within an instant. The golden vixen immediately ran forth and threw her arms around her friend, squeezing her midsection so tight that Angela could scarcely breathe. “I was beginning to think that this was nothing but a wild goose chase…I’m glad to see I’m not the only one who answered the ad!”
Angela hardly had time to react to the sudden pounce, but she squeezed her friend in her arms all the same with a playful grin. “I was a little worried that I might have missed it, myself. This is the room, right behind us, but I haven’t seen or heard from anyone yet.”
“Did you…y’know…try knocking?”
“Well, no…” Angela replied glibly. “I kind of figured that if someone were going to be here, the door would be open so we would know we were welcome to enter. Besides, why should the door be closed just to run some simple tests of a drug?”
Angela didn’t have a good answer for that one. “I’m not sure, really. That is a little suspicious…but we’re just wasting our time standing outside, right? I’m at least gonna try knocking.”
A simple knock knock knock yielded the desired results, as the solid wooden door opened inward.
Standing on the other side was a the archetype of a scientist, wearing nothing but black dress pants, a tucked in blue dress shirt, and a lab coat over the top of it all. He was short, compared to Angela, and right about on par with Kit, being a little shorter than the average male. Thin framed glasses kept a somewhat disarming and almost nerdy appearance about the young scientist, a quiet, timid fox with short blonde hair. 
“Ahhh, two more test subjects for the day! Wonderful. Come in, come in…I certainly hope you haven’t been waiting long,” the short fox bid them enter, and suspiciously, he immediately shut the door behind the two females. Of course, one glance around the room revealed why the door was shut in the first place.
The room was a bit dim, thanks to all of the windows being blinded and shuttered, but Kit felt her jaw dropping as she took in the sights that were clear as day to her. All around the room, small pumping machines were attached to hoses, and those hoses went right into at least ten nude females, all of them blown up around the middle two a massive size, easily six or seven feet around at the navel, and each of them had some sort of toy to suck on, muffling what would be a chorus of moaning. Angela was a tough lady to shock, but even she felt her maw going slightly agape as she tried to drink in the enormity of what she was seeing.
This couldn’t be more perfect, Kit thought. Little did she know that Angela was thinking nearly the same thing.
“I’m sorry that I wasn’t able to explain the testing process further before letting you in; you haven’t run away yet, so I assume that you’ve either been shocked into comas, or that you’d like to stay and see what we’re testing!” the fox said, trying to bring both ladies back to their senses. “My name is Jayden…you can call me Jay for short, if you like. I’m the head scientist conducting the use of the new fertility drug we made you aware of. It’s called ‘Prebudila,’ and you two look like you’d be perfect candidates to give it a try. We’ve yet to actually have a vixen or a dragoness to test the drug, so if you were still interested, please, step over to the desk with me so you can fill out your waivers.”
Kit and Angela simply stood in place for a few more moments, completely engrossed in the sight of all the females bulging at the stomach, and writing around on the floor in what was either deep, terrible pain, or the most blissful pleasure that one could experience. Given the nature of the tests, both females were hopeful that it was the latter.
“Are you two still with me…?”
It seemed that Jayden was going to be having to regain their attention all night long. “Oh! Yes…sorry about that. It’s just a little…fascinating, is all,” Kit finally responded, having to choose her words carefully as she watched with peaked interest.
“I didn’t know there would be a waiver. Hopefully this isn’t going to be anything dangerous?” Angela asked, towering over Jayden as he sat down behind the only desk in the room and pulled up a couple of forms.
Jayden set the two waivers in front of the females and shook his head. “We’ve already made sure that no ingredients that go into Prebudila can possibly harm you in any way, and the…growth, so to speak, should recess within an hour of the drug entering your system. Preliminary tests are showing no signs of stretch marks or excess skin remaining, so as far as we can tell, the drug has no side effects. Today, we’re testing a different aspect…that being the arousal of females who take the drug. If women who take Prebudila become too aroused by its use, we’d have to put restrictions on who could take it, and where.”
Kit and Angela showed an unusual haste as their eyes flew across the thick stack of papers before them, hardly taking any time to read the waivers in their eagerness. Though they weren’t voicing it yet, each one was thinking about the other the entire time, and how much fun it might be to have a little inflated fun together. “Well, sign me up! I could use the extra cash anyway…” Kit mentioned, adding her signature on the bottom line at the end of the last page. Angela quickly did the same, giving Jayden a devious grin.
“It’s nice to see you two are so eager already…that should give us a very good indication of how the drug effects your levels of arousal. Looks like you two are ready to go! I’ll file these waivers, and…uhm. Can I help you two?”
Just as Jayden was leaning over to place the waivers back in his desk, it shook and nearly bashed against his head. In the short time that the timid fox had been reading back through the waivers and placing them in the desk, Angela had wrapped her arms tightly around Kit’s waist and pushed her into the desk. Jayden felt an urge to rest one of the waivers over his groin as he looked up and saw the cyber-dragon’s large, soft breats pressed tightly to Kit’s perfectly sized pair, their bodies so close that the flesh of their chests nearly strained in the tight confines. A long, draconic tongue slipped past Angela’s maw as she looked Kit over, but instead of shying away, Kit obliged, pushing her hips right up to Angela’s body. Once again, they didn’t hear Jayden the first time, and it seemed that they could care less about his presence…but it gave the fox an idea.
“Hm…ladies!” he yelled, finally managing to get their attention as they turned to look at him, just as Angela had a clawed paw halfway into Kit’s kimono. “We’ve only been able to collect data on individual, straight females so far…but you two are clearly, well…at least on the fence about it. Perhaps the two of you would like your data to be collected together so that we can examine a new dimension of the drug?” 
Though Jayden was timid, he was just like any other straight male, and the sight in front of him was clouding his better judgment, if not making him forget about collecting data entirely. Lucky for him, it seemed the two sensual females were more than happy to oblige. “If that’s what you want, I’m more than happy to…” Kit replied, gasping as Angela finally got a hold of one of her peach fuzz furred breasts and squeezed it tightly.
“Quit pussy-footing around, fox boy. Hook us up to a machine already.”
Jayden gulped, wondering just what he might have gotten himself into as he stood up, holding one of the waivers in his paws still and keeping it hovering just in front of his crotch. It was becoming clearly obvious to both ladies that he wasn’t very good at keeping control of his body. “Y…yes ma’am,” he replied shakily, quickly scooting past the desk and in front of them in the hopes that he might hide the stiff tent that was sticking out from his pants, but a stifled giggle from Kit made it clear he had failed.
The short, timid fox led the two ladies to the far back end of the room, where one machine took up the back wall all by itself. It was a slightly larger pump, with two hoses coming out of it instead of just one. “Both of you, lay down next to one of these hoses…and disrobe, if you…already…haven’t,” Jayden stammered, as he turned around, only to see that Kit’s kimono was in a heap on the ground, and Angela was removing the last of her sleeves, placing it on the neat pile that was formed from the rest of her clothes. “…Er…in that case, just rest here on the floor, and I’ll get each of you hooked up.”
Kit flopped down to the floor, putting on a slight tease for Angela as she lifted her legs back, acting like a cute little puppy with her legs kicked up in the air, her breasts growing a little perky as he nipples were kissed by the breeze of the air conditioning in the room, and her labia shined against the golden-yellow of her fur. Angela took note of this and had to bite back on her desires to keep from jumping atop of her and ravishing her, but she returned the teasing favor, stretching her arms above her head to display the air of sexuality about her, from her massive breasts to her perfectly trimmed slit, often kept locked behind a strip of armor, but for this special occasion, the cyber-dragoness decided it was appropriate to show off for the vixen she was about to take. 
“That’s…that’s perfect,” Jayden said, as the lenses on his glasses actually started to fog. He was nearly drooling at the display in front of him, and he was sure that the girls were putting on this show just to tease him, though he couldn’t have been further from the truth; he was just a casualty in war of passion that was about to be waged. “Now, keep your legs spread for me. You’ll both feel a little bit of pressure when I insert the hose, and when you reach optimum limits, it should pop free from your nethers and leave you to explore as you see fit. Remember, you will only have one hour at most to record data, but it may be slightly less as we tamper with the product.”
Angela reached her paws underneath her buttocks and lifted her legs back, spreading them wide and glaring teasingly right at Kit, knowing that she was stretched far wider than she would ever need to be, but Jayden wasn’t complaining, and he fumbled with the end of the hose as he tried to contain his own lust. A small amount of medical lubricant was placed on the end of the hose, and Angela hardly even noticed it penetrating her body at how smooth it entered her. As soon as the hose was in deep enough, the drug started to flow forth, filling Angela’s womb first with a lukewarm fluid, causing an almost immediate bump. Kit was enjoying the show so much that she only barely noticed Jayden spreading her moist slit open so he could fit the hose inside of her, and having a slightly smaller body, she was a little tighter. She winced in a moment of discomfort, but once the flow of the drug started, she was well on her way to cloud nine. 
“I’ll leave you two to your business, then. As per security reasons, I must stay in the room, but…you won’t even notice I’m here. Enjoy yourselves, and feel free to do whatever comes to mind…we need the most honest data we can collect.”
With that, Jayden quickly stepped back from the machine and adjusted his glasses nervously, knowing that there was nothing he could do hide his raging hard-on at this point. He briskly made way back to his desk as the machine pumped away mindlessly, and within mere moments, each lady had a bulge in their tummy the size of a nine month pregnancy, at the very least. 
“You have no idea just how hard I’m gonna fuck you once that hose pops loose, Kit. I’ve been waiting to get you naked and in the mood for a long time…didn’t think that chance would…oooh…present itself today…” Angela admitted, but a sudden gasp broke her train of thought. Jayden had given no warnings of the side effects of the drug, likely to keep the data honest, so the cyber-dragoness was taken completely off guard when she felt a surge of pleasure that was just barely less than an orgasm. “Woah…woah!! Holy shit!”
Kit was enjoying herself deeply already, but she couldn’t help the distraction when Angela started writing as her tummy bulged up even wider. “Angela…is everything all…all…ooooh God! Angela!!” Kit screamed, and suddenly, she was riding the same wave of pleasure that she’d seen in Angela. Every nerve ending in her body was on fire as her tummy started to widen even further, and her breasts grew on top of the mound of flesh that was now her midsection, easily sitting at four feet around and still growing. “Angela…I think I’m gonna cum already…I don’t believe how hot this feels!”
Angela could barely catch her breath long enough to speak. The machine didn’t have the mercy on her to simply give her a release as the stretchy fabric that made up her body continued to grow, but each shock of pleasure she felt was like reaching the peak of orgasm, only to fall just inches short of it and have to try again. “Hehe…that’s…that’s the beauty of being a female, Kit…if you feel that urge, take it…cum once, and I’ll make you cum again, I promise you  that…” she guaranteed, keeping her arms around her tummy to see just how far this machine was going to take her body.
“G-g…good, cause I’m gonna…I’m gonna cum…holy shit…Angela!!” Kit cried out in a sudden and fast wave of orgasmic bliss, her whole body shuddering as every erogenous zone was hammered again and again with doses of the powerful fertility drug. The Prebudila was doing its job in droves as Kit could still just barely reach around the mass of her tummy, and she rubbed her pawtips furiously against her peaking clit, trying to draw out the pleasure she felt as much as her body would allow, but she soon found the greatest positive of the fertility drug: It was manipulating her nerve endings, putting her into a harsh and sudden state of heat, and just then, the vixen’s eyes narrowed harshly at Angela. “Listen here, dragoness…the moment these hoses come loose…you better fuck me til neither of us can walk, or I’m gonna have your ass…got it?”
“I…Kit…are you okay…?” Angela asked, spilling a mix of excess Prebudila and feminine arousal onto the floor as she watched her prospective lover orgasm so violently across from her, but her concern was with the words. She’d never known Kit to be that aggressive, nor to be so blunt with her words. It seemed that the drug had far reaching effects on the libido of whoever it touched, and when the effects appealed to their fetish as well, it was enough to simulate a heat cycle for a canine female. Jayden already knew this about it, but Kit was just having her first experience with the drug, and it was too much for her to keep control over. 
The first hose finally popped out of Angela, and Kit seized the opportunity, though as inflated as she was, she found it hard to move about. She turned to her side and managed to get in just close enough to lap hungrily at Angela’s soaking cunt, her long, canine tongue teasing all the way up and down over her slick, pouting labia, just before probing into her innards. The lust-driven vixen found the taste of Prebudila to her liking, and she became greedy in her tastings, drinking down all the fluids she could from Angela’s nethers, while driving the cyber-dragoness right to her first orgasm. “Kit…yes…good girl! Keep licking, please don’t stop…I’m cumming, Kit! Ahhhn! It’s…it’s too much!!” she yelled aloud, so much that it echoed the walls of the room, and suddenly, the pair understood why the other girls had toys to hold in their mouths. Still, the cyber-dragoness was completely overwhelmed by how sensitive the fertility drug made her. The sudden rush of pleasure that brought her orgasm was the most intense she’d ever felt in her life, and Kit wasn’t going to be stopped from her tastes, making each consecutive lick feel like another shockwave of pleasure for Angela.
Glub…glub…pop! The second hose finally popped free from Kit with a light splash of clear fluids upon the floor. At this point, the vixen was at least seven feet around in the middle, having a perfect, firm bulge to her stomach that she couldn’t quite reach around. Angela was nearly eight feet around, being of a larger frame, but she found herself in the same situation. Filled with affection and desire for each other, the two ladies sat upright and pressed their artificially grown bellies together in an embrace that was not full, and yet, was more meaningful than any other hug could be. 
“Go on and take me, Angela. Show me how bad you need me…” Kit growled lowly, the very essence of a vixen in heat about her as one orgasm was simply not enough, not matter how amazing it felt to her. “I wanna feel that perky little clit of yours grinding against mine…I want you to rub me raw!”
Jayden was watching breathlessly at the show unfolding before him. From the comforts of his desk, he could tease his throbbing length just a little bit and still get away with it while he watched Angela manage to push Kit over to her side. The rest of their bodies had remained normal, so their bellies could still sit tight together as Angela’s artificially large growth kept Kit’s legs spread perfectly for her. “I’m not just gonna rub you raw, my dear vixen…I’m gonna absolutely wreck you,” Angela warned, as her absolutely soaking slit slipped along Kit’s, the mix of fertility drugs and lady-nectar making their nether regions so slick, grinding down and into Kit’s pussy was going to be a struggle…
…But it was a struggle that Angela was up to.
“Do it if you can, Angela…and don’t you stop til I’m squirting all over your pretty little pussy!” Kit screamed, certain she was going to cum again as Angela finally hit home and pressed her slit down hard right against the horny vixen’s, splashing feminine fluids all across the floor as the drug was hard at work inside them, amplifying every aspect of their female sexuality. The nectar that flowed freely from their slits, the libido that drove them towards a need for a mate, the sensations that rocked every erogenous zone from the stiff nipples atop their swollen breasts to the tiny pleasure buds that hid just so perfectly under their clitoral hoods, and the hymn of pleasure that arose from their voices mingling…everything was brought to an entirely new level that neither lady had ever dreamt of.
Kit braced herself against her massive, bulging tummy, holding onto the firm flesh tightly as Angela ravaged her soaking slit. She could feel her second orgasm right on the brim, but she was so dizzy with pleasure already that she almost couldn’t grab onto it. She panted desperately as she managed to catch Angela’s eyes, met with a devious, bordering on evil stare, filled with all of the dominance and desire that Kit had come to expect from the cyber-dragoness, but pushed to the very limits that she was willing to go. The harsh slap of the vixen’s natural flesh against the rubber compound that made up the majority of the cyber-dragoness was even a turn on, and every meeting of their thighs brought a fresh slap, slap, slap into the air, driving Kit to near madness as she felt the Prebudila teasing her body just as it was meant to, making her hunger for a mate above all else, and she’d found a perfect match.
“I know you want to cum again for me, my dear Kit…do it! P…please…I can’t hold out any…any longer!” Angela admitted breathlessly, as each stroke of their clits together, separated by the delightfully firm flesh of their overgrown bellies had her inching closer and closer to an orgasm she could feel was already greater than the first. “I need my vixen to cum all over me…to squirt right down my sweet little fuckhole!”
The lewd, dirty words that filled the air were driven almost entirely by the Prebudila, and the level of the noise, not to mention the intensity were some of the best side effects that Jayden had found the drug to have. No matter how timid a female was, once she was dosed with the drug, it seemed they couldn’t do anything to contain their howls of delight, and Kit was finally able to give in to the drug one more time as Angela had one more trick up her sleeve…she rubbed Kit’s belly, right where the greatest mass of the drug was, activating it to its fullest potential. 
“FUCK! Yes, Angela…yes!! Fuck me…I’m cumming I’m cuuuuuuuuuuming!” the vixen screamed, unbridled and unabashed, as the building stock of her girlcum released with a sudden splash, and she squirted all over Angela’s sex. 
The pair were trading orgasms in that very moment, as Angela tensed up her entire body the best that she could, dripping sweat from the effort of fucking her mate so hard, she finally reached that gratification that she so hungrily desired. “Kit…KIT! YES! I’m cumming too, baby…don’t hold back on me…not even a single drop!!” she commanded, as her own juices gushed forth in a burst, and then trickled down slowly like a river, adding to the small puddle of feminine fluids and fertility drug that had formed beneath them on the floor. 
The room nearly shook with the boastfully loud orgasms of the pair, so much that every other female in the room had paused to watch, only to be driven to an orgasm of their own…the only one who hadn’t quite made it, it seemed, was Jayden, who sat behind the desk in utter disbelief of the experiment he had been assigned to run, but no less, his cock was ready to burst from his pants…but he’d have to worry about that himself.
This is probably the hottest thing I’ve ever seen.
**
“Sorry if we made too much noise. We really do appreciate you letting us take part,” Kit said as she took her payment from Jayden, the shy, timid fox now trying to use his lab coat to cover his tenting pants. 
The exhaustion of two orgasms so powerful took their toll on Angela and Kit, and the pair had nearly passed out from the exhaustion shortly after. As much as they wanted to shoot for a third, their drug was nearing its end, and the pair returned to normal size, and just as advertised, there were no side effects. If not for the fact that both ladies reeked of sex, no one would have ever known a thing of what had happened to them that day.
“No apology necessary, ma’am. We wanted honest results, and…I’d say we got that, for sure,” Jayden replied bashfully, handing over his payment to both females, and then, he gave each one a small pill bottle. “As an extra thanks for your particular brand of data, we’d like to give you each your own bottle of Prebudila, safe to use anytime and anywhere that you have…privacy. We’re working on a pill that can be taken anywhere at all, but the testing isn’t quite done yet. If you two would like, we could always use more volunteers for the next batch?”
The cyber-dragoness looked down at Kit with a devious grin, and looked back to Jayden knowingly. 
“Name the time and place, fox boy. We’d love to be of service.”
