"Getting Her Fill"

Dr. Helena Vuorela stepped though the massive front door of her home as she placed her keys in the basket next to her door. The gecko's big heavy steeps echoed slightly though her home as he stepped towards her kitchen. It was so nice to come home to a place built for a girl of her size as she reached into her fridge and pulled out a specially formulated protein shake. Forty thousand calories were packed into vanilla flavored drink making it one of the most nutrient rich substances on the face of the planet, but that's what it took to maintain Helena's massive size and physique.

Weighing in at a staggering 1500 pounds when fully pumped up, the gecko was the largest of her breed in the world. Her smooth blue green scaled head scraped eleven feet tall, and her shoulders were a massive six feet wide while the rest of her body was just as extreme. Extreme was perhaps the word that summed the gecko up best since she had worked so hard her whole life to get this way.

From an early age Helena had craved size, strength, and above all muscle in mammoth quantities. For a willowy young female reptile that meant steroids and a life time of pumping iron without end. By the start of her college career she was bigger than almost everyone but just being "big" wasn't enough for her. She craved the power and size that the PED's brought but had exhausted all the opportunity conventional drugs had to offer. It was time for her to take the next step and push herself even further, and to that end Helena enrolled in the finest bio-chemistry program in the nation.

Like everything else she applied herself to, her research began to pay dividends as she became her own guinea pig. Her advancements in muscle building drugs caught the attention of many even as her ever increasing size made some wonder at her sanity. In her last semester of college she made her greatest stride and compounded what would become her finest creation, Ubertrex. It was a steroid like compound with almost zero negative side effects and was soon being used to treat numerous types of muscle wasting diseases.

Jobs were practically being thrown at the newly minted doctor when she received a visit from the enigmatic CEO of the Sherex Company Lily. Helena saw in the gene spliced herm hedonist a kindred soul and someone who would not only understand her obsessions but encourage them. That didn't however stop gecko from letting Lily wine and dine her at an restaurant that cost more to eat at than two full semesters worth of books. She managed to make it through three courses before accepting Lily's offer and returning with the gorgeous hermaphrodite to the t-rex's hotel room were the pair spent a completely unforgettable night.

After graduation the muscle lizard moved south to Sherex HQ and was quickly plugged into one of the best R&D sections on the planet. Sherex seemed to be a match made in heaven for the power hungry gecko and it wasn't long before Ubertrex was even further refined. Soon the clever gecko came up with even more ways to feed her appetite for growth.

In order to ensure that she had a steady supply to feed her ever increasing muscle mass Helena developed an external delivery device that worked like a backup endocrine system. Similar to a giant insulin pump but on a crazy scale only someone like Helena could come up with. The machine was mounted on a magnetic vertebral rack surgically attached and wired into her nervous system and sat flush against her spine in the small of her back. A thin line of metal plate like scales that ran down the length of her backbone was the only outward sign of the vertebral rack, and depending on the size of the pump Helena decided to mount sometimes they couldn't be seen at all. A microcomputer at the base of the gecko's brainstem sent signals down her spinal column to control the distribution and output of any steroid pump she decided to mount, making sure the pumps continued to feed a steady stream of pure liquid power to each of her bulging muscle groups.

The Ubertrex got there through a network of clear plastic tubes. Depending on which pack she was wearing, the tubes could be quite large and numerous as they snaked around her bulging body and attached to metal plugs imbedded in her skin. The Ubertrex mixture she normally ran was slightly purplish and tended to make the tubes the same color. It also seemed to turn the thick webbing of veins that lined her hulking figure slightly purple as well. This gave the gecko a somewhat striking coloration when in the buff with chest, inner thighs, and the bottom of her thickly muscled tail being a lighter green color while the rest of her scaled body was a dark blue green.

The humungous gecko had no shortage of suitors and was quite a sensation on the internet, but Helena remained forever devoted to her own body as she looked at her reflection in the polished silver surface of her fridge. The giant reptile put down the empty carton of her protein shake and flexed one arm in front of her as she felt the fabric in her sleeve bunch their tear with a sharp 'RIPPP'.

"This just won't cut it," said the gecko to herself as she stared at the massive veiny peak of her bicep. While it might have been jaw dropping for a normal person Helena was actually at her smallest point of the day. The gecko wore a much smaller steroid pump to work that was only about the size of her purse most days. The flow rate wasn't near as much as she liked but certain sacrifices had to be made for the sake of work. Right now she was hovering around 1200 pounds which was practically puny and her small work pump was almost out of juice.

That meant it was time to pump up back to normal levels with one of her larger units as the gecko rubbed her paws together. She tossed her carton in the trash and walked to a door just off her kitchen. Like every door in her house, it was massive in size but it also had a security pad in front of it and no door knob. Helena keyed in the code as the door beeped and opened as the lizard began to descend the wide staircase into her lair.

While her house was nice thanks to her comfortable salary, the lab and gym in her basement cost almost twice as much. It was filled to the gills with cutting edge bio-compounding machines, and strength training equipment of the gecko's own design. The titan like lizard had long ago outgrown traditional weights and now used hydraulic and electromagnetic presses to grow herself further. The rest of the lab machinery was a smaller version of what she had at work and served her purposes quite well as the big gecko began to strip out of her clothing.

Like everything she wore her clothing had to be custom tailored to fit her figure, and every bit of it came off the minute she got home. Clothing was just a social nicety for the public and those at work when all it served to do was cover up what she had worked so hard to produce. Helena quickly hung up the blue business suit she had been wearing before walking over to a large raised dais surrounded by almost a dozen mechanical arms.

Clad in only a slinky throng stretched tightly over her wide muscled hips, the gecko went completely bra less thanks to a side effect of her long running steroid habit. One of the only things Helena regretted about her figure had been her complete lack of feminine endowments up high on her chest. She had always been jealous of chesty fems, and had completely destroyed her chances at developing a bountiful bosom when she began lifting and juicing. Her body fat percentage had been below one percent for years and was not conducive to growing a large set of sweater puppies.

For the longest time Helena had settled for a flat male like chest until Lily and Sherex produced a solution. Though some creative gene slicing Helena had managed to grow a chest large and eye popping enough to match the rest of her body. Perfectly round and prominent, they were the envy of many a fem and completely constructed of muscle. Built up on top of her already prominent pecks no one could tell the difference between her "muscle tits" and a normal pair, save that hers never sagged or caused her any back pain. Sherex was already beginning to market the treatment as a natural replacement for gel and saline implants and it was already receiving quite a bit of buzz thanks in large part to a number of nudes that company had used with Helena's permission.

She cupped them for a moment enjoying the sensation of her paws running over their vast firm expanse before tweaking her nearly shot glass sized nipples. They too had undergone some enhancement and were always dangerously close to bursting though anything she was wearing. The amount of pleasurable nerve endings there had been increased fourfold and doubled over the rest of her breasts allowing the lizard to cum without ever sending a paw below her waist.

Her teasing didn't go unnoticed by the rest of her body as her thick and prominent sex began to grow a bit moist, while the gecko's clit and meaty labia began to swell stretching her already taxed thong further. A line of moisture appeared on the front of her dark panties as Helena forced herself to stop and stepped up onto the platform.

She raised her arms to either side of her body and her paws warped around a pair of prepositioned grips as the machine whirled to life. Spindly arms descended from the celling began to gently detach the various lines connected to the fill sockets on her major muscle groups as a large arm reached down and griped the small pump attached to her spinal rack. The mag locks uncoupled and the arm lifted the pump clear of Helena's back as it disappeared into the ceiling with its numerous thin tubes trailing behind it like feelers on a jellyfish.

As soon another large arm appeared holding a pump unit more than twice the size of her compact work unit as it moved into position behind her back. The pump quickly attached itself and all of the spindly arms began to spin around the stationary gecko in a complicated dance. The machine was soon pluming Helena's body with the thicker plastic tubes, attaching each tube to the metal fill sockets embedded in her skin. The smaller pump used about half the fill sockets available on her body while the current pump used all of them and was designed for a much higher flow rate. It also held about three times the amount of Ubertrex cocktail her smaller pump could and allowed her to pump up to her full size.

A warm excitement began to build in Helena's belly as she felt the last of the tubes were plugged into her body. There were twenty four plugs in all, four in total on her arms and forearms. One was embedded into each shoulder, one beneath each trap, and one at the top of her delts. Each of Helena's breasts were fed by one plug each to keep them plump and firm. There also was a plug midway up either side of her rippling abdominals, and just for fun a plug on either side of the distended mound of her sex. A doubled sized plug was on the either side of her hips feeding her glutes, and two more of the same on the outside of both her quads feeding the largest muscles in her body. Lastly she had one plug at the top of either calf to make sure her lower body could support her upper one.

The network of tubes might have looked strange but the entire system had gone through so many advancements and refinements that the gecko had almost lost count. The entire apparatus spun 180 degrees till she was facing a mirrored wall. No matter how many times she did this it never seemed to get old as a specialized arm descended and plugged a thick hose into the top of her back mounted pump.

A purple liquid began to flow filling up the storage tank of the unit on Helena's as she felt her muscles tense and flex. She had made quite sure when developing Ubertrex that it wasn't physically addictive but she was quite sure that she and her body were completely addicted to the strength and power the drug brought. Some of her muscles began to twitch and strain as if they knew what was coming as she at last sent a metal signal to the machine on her back to begin pumping. The purple fluid was pushed out of the pump and into the tubes before being violently being forced into her eagerly waiting muscles. Purple veins popped to the surface of her skin around each plug as her body did the rest flooding every tendon, sinew, and muscle fiber with the super anabolic compound.

"OH GAWDDSSSSSS!" hissed the gecko girl as her whole frame began to twitch, throb, and then GROW! A read out of her vital signs was projected onto the mirror as she watched her body grow larger with hungry eyes. Her breathing was hard and heavy as she watched her biceps tremble then explode upward with even greater mass surpassing her previous flex while still at rest. The female reptile felt her back and shoulders pop and stretch as the muscles their fought for space, pushing her shoulders half a foot wider. Helena could feel her traps and delts thicken and tighten in a sinuous dace while he eyes watched the all-important number at the bottom of the mirror.

That number was her total weight, and pre-pump had hovered right around 1200 pounds. Now it was over 1300 and still rising as her legs shook and her sex clenched like and angry first. Helena had to fight not to plunge every finger she could fit into her churning roiling quim as the tubes on either side of her pussy pumped it up even further. Like her nipples the entire channel of her passage had been enhanced to deliver mind blowing orgasms. The twitching bulbous, and most decidedly angry clit peached at the apex of her folds had been enhanced far beyond what was probably safe as it stretched thicker and longer. Packed to the brim with enhanced pleasure nerve endings, just the feeling of her silky panties against her supercharged pleasure bud threw her head first into an explosive orgasm.

Like nearly everything about Helena, the gecko's climaxes were extraordinary. They were always toe curling, tail twisting, and heart stopping events where the lizard would nearly lose control of her formidable body as she gave herself over to her most base instincts. Her sex clenched and flexed swelling further as the muscles in her ass and thighs suddenly engorged adding almost a full hundred pounds to the lizards body. Likewise her tail thickened and lengthened twisting and thrashing behind her as her thong let go with a sharp snap.

Helena let lose a roar that was more dragon than gecko as shower of sticky lizard lust bust froth from her pounding sex. The first jet hit the mirror with a loud wet 'SPLAT' as her whole lower body clenched and the rest drizzled down between her legs. The pleasure hungry gecko sent a signal to the pump on her back to accelerated her steroid fill as the machine kicked into turbo mode and began pumping the cocktail into her muscles even faster than before.

With each fresh pump, Helena could feel the drug being forced into her muscles even harder than before, particularly in her lower body. Her quads, calves, and ass would spasm as more and more veins popped to the surface of her swelling muscles, and with each mighty flex Helena's pussy would fire a fresh round of her slick fem cum onto the ground and mirror. Each time she squirted it was harder than before as climax continued to grow along with the rest of her.

The lizard's upper body soon began to catch up with her lower as her breasts began to balloon larger. Already the size of basketballs, they were soon beach ball sized, flexing with each new wave of growth making her nipples positively ache with pleasure. The plus sized gecko wanted more than anything to paw at the rock hard nipples but her paws were still wrapped around the pair of grips attached to the machine, and it was the only thing keeping her body upright.

Her impossibly well-defined abs were scrunched up so tight she could barely move as each of the eight brick like abdominals almost doubled in size. Helena was an addict for the pleasures her own body could give her and knew just how to milk every last bit of ecstasy from her body as she began rolling her hips thrusting in time with each fresh squirt growling and howling as she did.

Her mind, foggy from the intense sexual haze, slowly began to clear as while her body started to relax by inches. After a minute or so she was able to put all her weight on her legs again and stand upright.

The view of herself fully pumped never failed to please her as she slowly eyed her reflection in the mirror. The vain lizard hit and explosive double bicep pose as she twisted her body and tensed her legs trying to force ever last once of blood into her muscles as she could. Helena cooed as she admired her tremendously pumped body while her sex managed to clench one last time further soaking floor beneath her. The weight readout at the bottom of the mirror rested at an even 1517 pounds and as her eyes saw it a brief bit of disappointment gripped her. It had been six months since she had crested 1500 pounds.

There had been a time when she never though she would ever be this strong, this big, or this gorgeous, but training, an iron will, and constant refinement of the Ubertrex cocktails she injected herself with had put her where she was now. Still as soon as she crested 1500 pounds she seemed to hit a wall. She was down a full fifteen pounds from last week and seemed to yoyo up and down no matter how much iron she pumped or how many gallons of roids she blasted into her muscles.

Helena loved the way she looked and pumping up to her maximum was just as orgasmic as ever but part of her very nature was the never ending quest for MORE! She HAD to get bigger. She HAD to get stronger, and the journey never stopped at least until now. This was the longest plateau in her growth she had ever experienced and it left her unable to cope. The gecko flexed again wondering if she had rung all she could from her body when her computed chirped at her.

She started to step towards it when she realized the state she was in as she looked down at the sticky mess she had made of herself. Her paw went to the terminal on the side of the platform as a screen descended and several drains opened in the floor. A quartet of shower heads were lowered from the celling as hot water began to beat down on the geckos body in waves. One of the arms passed her a bar of soap and she was soon scrubbing herself clean before getting one last rinse that washed the evidence of her deviant conduct away. The screen zipped back up into the ceiling as several large blow-dryers which soon had the female lizard dry as a bone before she at last stepped off the platform wondering how she had ever managed before adding all these neat features.

She padded with heavy steps over to her computer to see that it was an email from her boss Lily. In the body of the message were only the words, "Don't have too much fun!" and the t-rex's signature as Helena frowned and clicked on the email's large attachment. She was surprised to find that it contained a long but artfully written paper on the possibilities of using newly emerging nano-machine tech to treat endocrine and autoimmune diseases.

It was pretty dry reading but still interesting as Helena pulled up a chair and began to skim through it. Her pulse began to race as she read one portion in particular, but she forced herself to finish the document before feverishly turning back to the section that interested her. In the paper the author suggested using nano-machines as micro injectors that ached directly on the cells themselves keeping levels of desired chemicals within the microscopic bodies by attaching themselves to the cells and acting as mini chemical warehouses and regulators. This would vastly improve absorption of vital medicines and allow the user to tailor the treatment of drugs inside his or her body down to the cellular level.

From her own research Helena knew that most drugs, steroids included, only had about a forty to fifty percent absorption rate into the body's muscular system. This rate could be manipulated in various ways but an uptake rate over fifty five percent was almost unheard of. Practically, it meant that half the Ubertrex she pumped into herself was completely wasted when her cells couldn't take in anymore of the drug. Her solution until now had been to try and build her body through extreme strength training, and increasing and refining the Ubertrex compounds she injected herself with. Just the idea that she could have an army or tiny soldiers forcing even more of her steroid compound into every one of her muscle cells made the nude gecko a bit moist as she leaned back into her super heavy duty chair.

Mind ablaze the gecko turned on some hard pounding techno music before getting up and heading over to her stationary lifting equipment. Helena was more excited than she had been in quite a while as she spread her legs and placed her shoulders under the yoke of her hydraulic squat press machine. Two large pistons extended down from the ceiling and attached to either side of the thick steel shoulder bar. She pressed a button near on of the paw grips as two tons of force settled onto the lizards massive shoulders.

Ass up and tail high with her back straight, the gecko began pounding out rep after rep as her already huge legs swelled even further. Her eyes were blank as she let out a low grunt with each finished each rep but Helena was already thinking about how she could repurpose the program she used to mentally control her various pumps to direct nanobots inside her body.

Sweat dripped off her body as her grunts grew more fierce and her legs heavier. The rep counter above her head was already into the triple digits but the she lizard was so in the zone she didn't notice as she continued to force her muscles to work even harder. Five tones pressed down on top of her and it still wasn't enough as the pillars of swollen muscle that were Helena's legs began to shake with each lift while her grunts grew into roars. It was harder than she had pushed herself in years, but her excitement was turning to pure adrenaline which powered her epic workout.

The idea that she could force the nanobots to pump up any muscle group she wished and have an even greater control of her body's shape had her proud sex clenching and dripping as more silky fluids ran down either side of her trembling thighs. One finger hit the MAX button on the controls near her paw as the machine above her had groaned and tried to send her through the floor. Every single ripple and swell in the gecko's body seemed to clench and flex as she forced the yoke around her shoulders skyward.

Helena could never remember her legs being more tired as she started on her second rep at the machine's maximum setting. She had never done more than two even on her best day as he breaths came in raged gasps. The already thick veins that scored Helena's heaving leg muscles were swollen nearly twice their normal size as blood and Ubertrex swirled through her body. Something in her forced her to try for a third rep as she paused for just a second at the apex before she controlled the weight all the way down until her thighs were parallel with the ground.

The journey upward was an agonizing affair that seemed to strain every sinew and cord in her body right to her core. With a herculean roar the Gecko's body seemed to explode upward. Helena's eight bricklike abs stood out in stark relief, as her biceps flexed, and the mountain range that was her back seemed to erupt. The machine above her let out an audible groan as she threw herself against it, clawing for each inch as swear dripped off her body. Her legs were shaking in an almost violent fashion as Helena's iron will was tested and measured till at last she reached the climax of her lift. Excitement thrummed through her body at her accomplishment as her sex clenched hard and began to celebrate.

The gecko was barely able lock the machine in place before her legs fell out from under her and a paw cupped at her thick gushing pussy. It had been a while since she had cum pawfree from a workout and it was always an enjoyable experience as she slowly recovered. When she at last stood Helena's legs felt as pumped and engorged as she could ever remember them to the point where they were quite stiff. One paw trailed slowly up her thigh marveling at how rock-hard her quads were as she hummed softly and padded over to her mirror.

A few slow flexes were enough to show how massive her pump was as her hungry eyes soaked in the view from every angle. In the end the she lizard had to tear herself away from her own reflection in order to go and grab another shake from her basement refrigerator. She took a minute to drink the protein packed beverage and towel off before moving over to her hydraulic bench press to begin pumping up her upper body.

An hour and three shakes latter every single veiny muscle was as pumped as she could possibly muster as Helena stepped onto her mechanized platform again. The shower heads reappeared and began bathing her tired sore body in warm water. She gently cleansed herself as she eyed the weight readout on the screen in front of her. It sat at 1528 pounds and she enjoyed every last ounce as her paws roamed her colossal form.

The water shut off as a warm blast of air hit her and she mentally checked the amount of Ubertrex remaining in the pump riding on her back. The computer at the tip of her spine made the number 61% appear to float in the bottom left corner of her vision as she sent another wireless command for the machinery around her to top her off. A nozzle quickly descended and began refilling the pump on her back as she felt the fill pressure jump ever so slightly throughout her body. Her muscles consumed Urbertrex at an accelerated rate while lifting but it was almost as important to keep them pumped full of the substance post-workout as they rapidly healed and mended.

A few more mental commands made the pumping unit attached to her back increase the flow rate to her muscles as she felt the gentle pressure in her body tick up another notch. It had been a rather brutal workout after all and even it if wasted a bit of her mixture it was worth it to prolong this wonderful full pumped feeling as long as possible. The gecko was starting to wonder about what to do for dinner when her doorbell rang. It was rather late for guests, so as she gingerly made her way up the stairs, she wondered who it could be. The doorbell rang again and the screen beside her door blinked on showing her a crisp image of who waited on the other side. What she saw made the Geko chuckle and grin as one big paw reached down for the doorknob.

The eight foot tall chocolate colored stallion stood looking rather impatient on Helena's front step. His name was Blake and he was dressed in the familiar form fitting tan uniform of an Express Parcel Service employee because he was one. In his left paw he held a silver package about the size of a lunchbox covered in bright red lettering. In bold on top of the box were the words "URGENT DELIVERY" which meant that the package in his paw had probably cost several hundred dollars just to ship. Urgent Delivery was the fastest postal rate EPS offered and would have any size package delivered anywhere domestically within twenty four hours or your money back.

Blake had never before delivered an urgent delivery parcel but his curiosity was rapidly evaporating as he stood looking at the green door in front of him. He had been on his way home looking forward to a Friday night bar crawl with some friends and a high very likelihood of some pleasant female company.

From the ground up Blake was all stud and the trademark tightfitting EPS uniform with half knee short shorts delivered. Since high school the equine had been a rabid gym bunny and his hobby helped him a lot with his job as well as catching the eye of the fairer sex. At nearly four hundred pounds the stallion was built and if his physique didn't catch the eye his own personal package was just as impressive.

He snorted as he glanced slowly at the watch strapped around one thick wrist and his grip shifted on the tablet he held in one paw. Something bothered him about the door he was standing in front of till at last he realized what it was. It had looked almost normal from the road but standing next to it the thing was huge as his finger reached out and pressed the button for the doorbell again. It was built for someone even bigger than he was which was saying something since he seemed to do a lot of ducking around doorframes. The door finally started stared to open as he looked down at his tablet and keyed up the customer signature when he at last saw the nude gecko lounging in the doorway. His tablet hit the ground with a thud and his chin followed as he stared open mouthed at Helena.

Somehow the gecko managed to keep a straight face as she looked down at the very cute horse who was ogling her. It was a reaction she savored as put one paw up high on the door frame and the other on her hip. The reaction she got was telling as the horse nearly dropped the package he was carrying, fumbling with it for a moment before wrapping it up with both arms and squeezing it tight to his chest.

The thin material of his uniform did little to hide his muscled body, of which Helena approved even if he wasn't quite on her level. Still it did little to stop her eyes from running up and down his body once or twice or taking note of the heavy looking bulge that rested between his legs.

"May I help you?" asked the gecko in her friendliest tone.

"Y-you! Y-you're Helena Vuorela! T-the Gecko Goddess!" sputtered the stallion as he stared upward.

"How did you guess," said Helena with a wink. "You must be a fan."

"Oh my gosh, I'm your biggest fan ever!" said the horse as he practically bounced on his hooves. "I followed your whole carrier, and I own all your videos!" he stammered.

"All of them?" asked the gecko as she remembered one or two that have been closer to pornos than flexing vids.

"Y-yes," said Blake looking slightly embarrassed as he caught his idols eyes. "C-can you do one thing for me though," said the stud looking a bit sheepish.

"You need an autograph?"

"No uh, do you think you could..." he flexed his arm to demonstrate as Helena laughed and nodded.

"Sure I can! No use having these babies if you can't show em' off!" she said as she stepped out of the door frame and curled both arms. With a grunt she flexed as both her biceps exploded upward. Each veiny mass reaching for the sky as the gecko felt them engorge with blood. She let out a deeper groan and hit a crab flex as veins popped and Blake nearly fell over. A quick pec bounce had her wondering if the stud was going to fall out as she decided to go for broke and roared loud enough to blow his mane back as she hit a titanic most muscular. For the cherry on top she then lifted one arm and while maintaining her flex gently kissed her bicep.

Watching the Gecko Goddess flex was too much for Blake as he grew dizzy. She looked even bigger than in pictures or videos and all that herculean brawn so close to was just too much. The macho stallion promptly feinted dead away as he fell backward. His head bumped the pavement just before Helena darted forward to save him and snatched him up. She promptly threw him over one shoulder and grabbed the package and his tablet with the other as she closed the door and carried him into the kitchen.

The concerned gecko laid him out on island countertop in the middle of her kitchen as her fingers checked where he had bumped his head. The skin wasn't broken but it was starting to swell a little bit as she glanced down to see the horse's cockhead peeking out the left leg of his shorts.

She sighed scolding herself for pushing the show just a little too far even if the results did nothing but turn her on. Her exhibition streak had gotten the best of her again as she tried to calm down while her paws roamed the horse's toned body. Blake murmured something as his eyes looked up and her jerked like he had been shot.

"Am- am I in heaven?"

"Nope you're in my kitchen. I think you fainted and then bumped your head," said Helena as she turned towards her fridge and reached in to grab some ice. The gecko quickly wrapped then in a dish towel and gently placed them against the horse's head as his paw quickly replaced hers.

"I uh- that's never happened before," said the stud more than a little embarrassed.

"Aww it makes a girl feel good to get that kind of reaction. Plus I think it might have had something to do with rapid blood loss," she said pointing at his crotch. Blake jerked upward as he used his paws to try and cover himself while his face grew even redder.

"I- uh- I'm so sorry I didn't-

"Honey If I didn't want that reaction I wouldn't work so hard on this," said Helena flexing again. That make Blake's cock throb even harder as he groaned and the gecko laughed. She then picked up her package and flipped it up before promptly ripping the top off the box. Inside was a much more sturdy polymer hard case with a few clasps that her fingers had open in a second as it at last revealed her prize. There sitting in the case was a sealed glass vial marked "NANOMACHINES" and a small sender receiver unit about the size of a cellphone.

"Um, I'm going to need you to sign for that Miss-

"YEEESSSSSSSSSSSS OH GODS YESSSSSSSS!" shouted Helena suddenly as Blake nearly fell off the counter. She hadn't expected to actually get her hands on these for several months. Lily must have moved heaven and earth to get her a batch so soon and next time she saw that T-rex she was going to show her just how grateful she was. With the nanomachines in her paws she could start her new program TODAY! Depending on how fast they multiplied she could be pumping up within HOURS! The though had her loins completely drenched within seconds as a low moan split her lips.

The very idea that more size was within her grasp had her mind spinning as she glanced up at the cute horse. As much as she wanted to do this right now, pumping her body full of experimental nanomachines wasn't the smartest without some kind of supervision or at least someone to call an ambulance if things got out of hand. It would be much safer to have someone with her just in case the worse happened, and maybe to take the edge off while they waited...

"Um ma'am are you alright," said Blake trying very hard not to stare at her flushed and dripping sex.

"What did you say your name was?" asked the gecko turning her full gaze on the horse as she turned the charm all the way up.

"I-its Blake," said the stud as he watched Helena's tongue trace her lips.

"Blake I'm going to be brutally honest with you. I have the chance here to try something here today that could be a little dangerous, and I need your help."

"My help? What could I do, I just deliver packages."

"Well what I've got here in my hand is an opportunity to make myself even bigger!" said the gecko quickly as she held up the vial. "Would you be interested in watching me grow even larger even if it meant you had to cancel your Friday night? It would mean a lot to me." Blake's cock gave a visible twitch as he began nodding his head so fast it actually hurt.

"Anything you need! I'm your stud!" he exclaimed as Helena leaned forward and gave him a soft peck on the cheek.

"Mmmm, such a gentleman," she said as one paw casually stroked the exposed fur of the horse's thigh. "Come with me then," said the big female as she turned and motioned with a finger making the horse obediently trail after her.

Blake couldn't believe what was happening. Never in a million years had he expected to wake up today and meet one of his idols. Gods the gecko was so hot and her body almost defied description. She was defiantly bigger than in her last photo shoot. Her obsession with her size was part of what attracted him the most since he had a little bit of that same drive in himself, but to see the lengths she would go to made him all the more impressed.

The setup she had in the basement was beyond extraordinary as he stood around while the gecko went to work. Blake supposed that she couldn't just go to the local gym to get her pump on and needed the stuff she had down here. Like most of her fans he knew a little bit about her hulking steroid pumps and the aids she used to get so huge. It was a little bit intimidating as he eyed the ling lines of purple tinged tubes that fed directly into her hungry muscles. There was a sizable faction of bodybuilders who looked down on those that used such methods to get big, and Helena was one often one of their targets since she was a popular face of the pro-PED movement.

While some did feel it was 'cheating' to his knowledge the gecko had never held herself out as a drug free competitor and also didn't compete in competitions were PED's were banned. It was also frankly impossible for her to reach her current size without using steroids and other PED's and she had never been shy about telling her fans this fact.

Blake had been very curious about the Ubertrex compound but had so far held off using it. He enjoyed his job but wasn't wealthy by any measure and Ubertrex was one of, if not the most expensive PED's thanks to its how in demand the drug tended to be. His natural results had been enough so far thanks to good genes and a healthy work ethic. Still the more he stared at the gargantuan lizard the more he wondered what it would be like to be that big.

Helena's paws were almost shaking as she hooked the nanomachine transmitter up to her own computer and downloaded it's OS. The nanobots received signals like a host of other mundane household wireless devices and possessed their own wireless network which let them communicate with each other and receive instructions from their controller. After downloading the programing into the microcomputer at the top of her spine she stared to program and pinged the nanobots in the vial.

She quickly received a reply that told her 99.99% were responding as normal as she sent a query on their projected reproduction rate. When the numbers came back, she was more than giddy as she moved over to her large Ubertrex storage tank. The muscle lizard opened an auxiliary fill port at the top of the clear polycarbonate tank and dumped the entire contents into the it. Almost immediately after being dunked into the purple mixture the bots began to multiply as Helena's internal computer began to keep track of their numbers. In just thirty minutes they would be at full saturation as she rubbed her paws together.

She sauntered over towards where the stud was standing, catching more than his eye as she did. The brewing nanobots had the gecko so excited that her perpetually moist netherbits were clenching and dripping as liquid lust seeped down her legs. She saw the hungry look on the studs face as his cock stretched the integrity of his shorts and her finger went to the underside of his chin.

"So Blake we've got a bit of time to kill? Got any ideas?" she asked with a seductive smile.

"I've got more than a few," he said quickly as one of the gecko's paws tailed up the hard expanse of his chest. Before he could react on of her paws grabbed a handful of his shirt and ripped it away from his body.

"Oops," said the gecko. "Clumsy me."

"It's just a work shirt. I've got a bunch more," said the horse more turned on by the gecko's display of strength than anything.

"How about shorts?"

"Plenty of those too," he said as both her paws moved to his waist before splitting his shorts and underwear right down the middle. She tossed both halves away before pressing the horse's body into her much larger one.

Blake let out a muffled moan as his face was pressed into an endless bounty of impossibly firm tit flesh while his paws grabbed onto as much firm gecko ass as he should. The body he had drooled over was now firmly within his grasp as he squeezed at the unyielding muscle of the lizards backside and nuzzled within the canyon of her cleavage.

He let out a happy whiny as Helena did some groping of her own. The fact that the horse was so turned on by her body was turning her on in return as her palm gave a frim slap to the stud's rump. She could feel the horse's impressive hardness throbbing against one of her thick legs and while the idea of taking that thick shaft all the way to the hilt was enticing she wanted to be ready when the batch of nanobots was finished.

"Say Blake how long can you hold your breath?" asked Helena as the horse pulled his head back and looked up.

"Hold my breath? Why do you- oh..." he said as her gaze flicked downward. The muscle lizard then sat down in her reinforced chair and placed both paws on her knees as she spread them wide giving him an eye full of her glistening folds.

Blake was no stranger to pussy but he had never see one quite like Helena's up close. As his muzzle mover closer to his target he couldn't help but notice how muscular it looked. It was as if the gecko had figured out a way to make that part of herself just as strong as the rest of her body. The twin tubes pumping it full of Ubertrex probably had something to do with how healthy it looked but as his tongue started at the bottom of her opening and moved towards her clit he felt it clench and wink while she shifted above him. He warped both his arms around her huge thighs as his tongue plunged in deeper and he felt her body tighten and flex. Soon he had a rhythm going and the gecko was almost thrusting into his mouth as he drank up her sweet honey.

The stud began to feel quite proud of his efforts as he watched Helena's reactions. Her tongue was hanging out of her mouth as she let out a series of groans, moans, and coos, and she couldn't keep still. The gecko's massive quads and abdomen tensed and strained under Blake's oral assault, and just when she thought she couldn't take anymore his tongue flicked up and over her clit.

Like everything else about the lizard it was oversized and from the sounds she was making extremely sensitive as the equine began focusing all his efforts on her pleasure bud. He rolled his tongue into a 'U' as he lapped at her twitching clity and it didn't take long for the dam to break. Helena soon roared her approval and began painting Blake's muzzle with her juices.

The horse was almost alarmed at the duration and intensity of the gecko's climax as her whole body rippled and heaved. He was just about to pull back when her thighs tightened around his neck and a strong paw grabbed the back of his head. Helena's pussy was still squiring jets of sticky fem lust when she shoved the horse muzzle first back into her sex, howling as she did it.

With no other way to go than forward, Blake took a deep breath and sent his tongue as deep into the lizard's as he could. Praying that she was just as sensitive on the inside as the outside, the horse set his paws to work stroking and playing with her fat clit. He was unsure if the gecko ever really stopped cumming since her insides never stopped clenching but soon enough she peeked again as she threw her legs wide causing him to topple backward.

Helena couldn't keep her paws out of her pussy as she reveled in the feelings the horse gave her. One paw went to work on her clit while the other's fingers plunged inside trying to extend her pleasure as long as she could.

The stallion flopped back onto the ground as he was showered with more of her juices and got a front row seat for the show. His ego soared as he watched his handy work and smiled at a job well done.

Helena at last gained enough sentience to grin down at the stud as she withdrew her fingers. Perhaps he wasn't the best she had ever had but he was certainly a contender and she knew just how to reward him as she eyed his footlong stallionhood. Before he could react she bend down and grabbed him by the hips and hosted him up until his crotch was eye level.

Blake let out a panic whinny at being to very high up, but as soon as Helena's tongue snaked out and wrapped around his cock he forgot about all his fears. The gecko's long flexible appendage crawled down the studs cock like a candy cane stripe, squeezing as it went. He was so nice and thick there was a lot to grip as she briefly kissed his spade shaped tip.

Her next move shocked Blake even more as her arms raised him completely above her head till his cock was pointing straight down. Her tongue retraced teasing him for just a moment before she lowered his body and swallowed his cock to the hilt until her muzzle was pointing straight upward flush with his groin. Almost before he could enjoy the warm tightness of her mouth the gecko pressed him upward, lifting him until his cock was almost all the way out of her mouth before lowering him again.

This astounding display of strength combined with a world class blowjob had the stallion panting and moaning as he thrashed in her grip. The gecko began to effortlessly press the big stallion up and down inhaling his cock each time. Her grip didn't allow Blake to do a thing as Helena used him to fuck her muzzle faster and faster as she bounced him up and down like a pogo stick.

The muscle lizard's tongue was soon working the equine's cock in tandem as Blake felt his balls churn. He tried to hold back but the experience was just to much as he felt himself twitch and then explode in the grinning reptiles mouth. Helena hilted him again as he cried out and blasted his load down her throat while she gulped down his seed.

It was an impressive finish as the gecko slowly cleaned him off before placing him back on his own two hooves and smacked her lips. Blake was a bit woozey on his feet as he leaned into Helena and mouthed a low "Wow!" as she churred above him.

"Mmmm you were pretty good too stud," she said as she leaned down to kiss him again. Her computed dinged, as her head snapped around and she dashed over to the Ubertrex storage tank she had placed the nanobots in. Her sensors were picking up signals from a staggering number of the microscopic machines and visually the normal purple Ubertrex mixture was now emitting a neon purple light. The glow was a bit off a surprise but thoughts of growing even larger put off any reservations she might have had as the gecko ran over her filling platform.

Blake, still a bit shaky on his feet, trotted over to watch as Helena stepped up on the mechanical platform with a light tremble in her paws.

"Err, Helena do I need to do anything?"

"If all goes well not a thing," said the lizard as she held her arms outward and a set of mechanical arms again descended from the celling latching onto the pump mounted on her spinal rack. Another hose snaked down and began draining what was left in the pump's reservoir as she felt the pressure in her muscles subtly decrease. After it was done the glowing Ubertrex mixture began flowing into the tank on her back as she felt the computer at the base of her neck communicating with the bots.

Blake watched mystified as the tubes routed to Helena's many bulging muscles were emptied then filled with the new softly florescent purple drug. Almost immediately the gecko noticed a difference between a normal pump up and the new nanobot infused Ubertrex mixture. It seemed thicker and didn't seem to be absorbing as fast as the pump on her back kicked up the pressure to compensate.

Already swollen and full from her earlier workout, the thicker Ubertrex made the tightness in her muscles increase even further as Helena sent the signal to the nanobots to begin coupling with the muscle cells present throughout her body. A heat began to spread from the fill ports that dotted her body as deep tingle washed though the reptile's muscles. The added pressure and sensation of the nanobots working along with the idea that she was finally going to push past her plateau make the gecko squirm as she whimpered with pleasure.

Helena muscles had never felt so filled as they pumped up larger than ever before as a soft orgasm rolled through her. Blake watched drooling as an added layer of definition was added to the already ripped lizard. Her muscles slowly twitched and swelled larger as even more veins popped to the surface of her skin. Now the snake like blood vesicles feeding her swollen muscles actually glowed purple as the jerked in time with her heart beat. Seeing as the lizard now probably had more Ubertrex in her blood than actual blood the glow was not very surprising as the hose filling up her pump retracted into the celling.

The network of nanobots with in Helena's body was giving her second by second updates of their progress as they attached themselves to each and every muscle cell in her body. Her arms came down onto the support rails on either side of the platform as her chest heaved and she felt he added mass throughout her body. Along with the rest of her, the muscle lizards prominent tits looked slightly bigger as she turned around to stare at the mirror. Likewise her legs arms ass and tail all looked a little bigger as she slowly flexed.

She had never before been this vascular, as the purple glowing veins along her skin popped when she flexed and shifted but something wasn't right. As she stared longer at her body she noted that instead of the rock hard look her muscles normally had, they looked puffy and swollen like someone who had done too many of the wrong steroids. Her muscles hadn't looked like this since the earliest days of her journey towards bigness as a frown crossed her face. The weight counter on the bottom of the mirror showed 1598 pounds which was a tick up but not nearly what she had been expecting. A little bit disappointed in her progress the gecko stepped down from the platform as the horse moved towards her.

"You look amazing!" he said excitedly as she put on a happy face.

"I'm glad you think so."

"Not happy with how it turned out?" asked the stud as he detected a bit of disappointment in her voice.

"A little bit," said Helena as she wrapped one big arm over the horse's shoulders. "I really thought these machines were going to take me to the next level.

"But you look so huge!" said Blake as one paw palmed her abs. "I mean is there anyone even close to your size?"

"It's not about being bigger than anyone else, it's about reaching my potential," said Helena. "I know it's an obsession but if I'm not growing I don't know what to do with myself."

"Well I think you're gorgeous and big enough for any man," said the stud as he leaned forward and lightly kissed the top of the gecko's abs.

"Oh you are a charmer aren't you," said the gecko as her face seemed to brighten. "I suppose I couldn't interest you in some dinner then?"

"Mmmm what did you have in mind?" asked the horse as he grinned and pressed his body tighter against hers.

"Well I was thinking about ordering out then snaking on some nice big thick stallion until it arrived then having some more horse for desert," she said as paws found his firm rump again.

"Sounds appetizing!" said Blake. "Who's the lucky stud?"

"I think you know him," said Helena as she kissed him on the forehead and pulled away. "I'm just going to call out for some-

Blake waited for her to finish her sentence but it seemed the huge reptile was frozen in place as he stepped forward and waved his paw in front of her face.

"Uh Helena are you-

Her head flicked down in a jerky mechanical fashion as he saw her pupils blow outward and a thin line of drool drip from her muzzle. Before he could question her further her jaw snapped open in a loud gasp as her paws clenched into fists.

"Helena! What's-?!

"The nanobots haven't activated yet!" she panted as her chest began to heave and a fine tremble ran through her body. "They're startiinnngggggggggg!!!" she grunted as all her muscles erupted simultaneously flexed erupting to their maximum size. Every vein visible on the gecko's body bulged as her blood pressure spiked and she let out a ground shaking moan.

The nanobots had been franticly busy the instant they had entered the Helena's blood stream. Now over 99% of her muscle, tendon, and ligament tissue cells had several small bots attached to the outer cell wall with small micro-injectors spider webbed throughout the cell body. Rather than pumping however the bots next began wiring the big lizards body with a fiber optic neuronetwork that temporarily shocked the gecko's brain with all the additional input.

Helena could barely think or move as the sheer amount of sensory data overwhelmed her. There was simply too much to feel as the just the sensation of the air running over scales and her body rubbing against itself nearly drove her to her knees. Never before had the gecko been able to sense each individual muscle but now it appeared she could isolate and flex each one as the nanobots wired themselves into her brain and the computer attached to her brain stem. It took several moments for the network of bots to adjust the intensity of their signals as the musclebound she lizard gasped with relief.

"Oh Gods! Helena are you alright?!" shouted a panicked Bake as he looked up.

"Nooo0oo.... I-I'mmm feeeine..... nano000s ajjuuuutstingggggg.... Toooo b-b-bbbody," said Helena with a bit of a slur as she straightened up. It was still hard to move with her body fully flexed but she managed as she at last began to regain some control. The network of nanobots were now a part of her much like her internal computer was and they were transmitting one simple query directly to her brain.

<BEGIN PUMP? Y/N>

"YESSSS!" hissed the lizard as the Ubertrex pump on her back hummed to life and she felt the fluid begin forced into her already swollen muscles. Helena felt like a balloon about to explode as even more of the purple muscle juice slammed into her body. The nanobots reacted to the new rush of Ubertrex and what was already in her blood as they began to consume it then force it into the cells they were attached to.

Blake jumped as Helena let out a deep feral like grunt before she stretched her whole body wide. He felt the thump as both her feet came down cracking the floor and he couldn't look away as her whole form seemed to clench. That lingering bit of puffiness in her figure from her first injection of the nanobots melted away leaving her looking harder than ever, but the drooling horse noticed something else as well.

Each one of the lizards major muscle groups was twitching almost violently now with each pump of the machine on her back, and with each jerk the veiny mounds of brawn grew bigger each time. With a roar the great she beast's tail slapped at the floor as her calf muscles detonated almost doubling in size. It drew her feet upward as the massive ball of sinew stretched tight forcing her to stand on clawed tiptoes. Her quads seemed to receive the most attention next as a series of violent spasms seemed to grip them. There was no explosion of brawn only a steady relentless expansion as the mighty gecko moaned and twitched. When they hit their apex Blake knew even with both arms he wouldn't be able to wrap his arms around one leg.

Helena could feel the mightily pillars beneath her throb with power as the sensation rushed up her spine. She let loose a cry as her sex clenched and soaked the massive expanse of her inner thighs. The way the muscles of her impossibly thick legs pressed against her swollen vulva felt incredible and just moving was getting her off as she felt the nano's in her tail and ass kick into high gear. Soon her muscular rump was more than a match for the rest of her lower body as her tail flared and thickened while it trashed behind her. Through it all her her wasp like waist stayed almost impossibly thin as she felt the transformation move up into her groin.

Barely finished with its orgasmic contractions, the nanobot's went to work on the breathless Gecko's drooling sex with all the subtly of a hammer. Helena's love tunnel was forced into an explosive second climax as her sex thickened pushing out even further while her inner muscles strengthened. The star stuck fem found that she could now clench each part of her pussy like she could her paw thanks to the enhanced control the nanobots provided, and the extra sensory data that nano-network fed into her brain seemed to make those parts of her even more sensitive. It was too much for her heaving body to handle as the gecko made the hat trick and soaked the floor beneath her again.

Blake watched as the lizards hypersensitive clit seemed to swell and grow even larger, while it throbbed softly above her folds. It would jerk each time her sex squirted and the desire to wrap his lips around her thick nub was driving him mad. Only the fear of begin crushed stopped him from burring his face between those mountainous thighs as Helena roared again and her abs seemed to flex.

No matter how hard she worked Helena had never been able to achieve a ten pack. Though the eight she had were always huge and sculpted, the reptile had always lusted after that elusive fifth pair of abdominals and now it seemed she was going to get them as her stomach tightened stretching over abs nine and ten. While the rest of her core didn't gain much mass, the gecko felt it all grow stronger as the cells of her muscles began to braid themselves into dense spiral weaves thanks to nanobot manipulation. Amazed at their seemingly endless ability to adapt, the gecko clenched her stomach as the lines and creases on her front and back grew deeper. Excited at the possibilities of what the nanobots could build on the fantastic foundation had created, her joyous voice shook the room.

"YES! GODS YES LET ME GROW!" howled Helena as her paws shook with excitement. It was at that moment that the one thing that could have dampened her sprits happened. The tank on her back which had been pumping at max fill for several minutes ran dry as a signal was sent to the gecko's brain. Her joy came to an abrupt end as the crestfallen female looked down. Her lower body looked better than she had ever dreamed but her upper body was still mostly the same. It would take refilling her pump again before the nanobots could do anymore as she growled out her frustrations.

She turned heading for her platform when several of the clear plastic tubes attached to her fill ports released with a series of sudden soft pops. Helena froze, wondering why this was happening without her giving the command, only to have the rest of the lines come lose until they were all dangling from the unit on her back.

Blake opened his muzzle to ask what was happening when the mag locks on the gecko's spinal mount released letting the bulky pump crash to the floor. Helena turned in confusion as she checked her internal computer for errors only to find that the command to jettison the unit had come from inside her own body.

"Is something wrong?" asked Blake, unsure what to expect next as the gecko ran a paw over her head.

"Something is definitely screwy," said Helena almost breathlessly as she ran her paws over her still trembling hips. "I was about to refill when the nanobots ejected my pump."

"Don't you need it to, uh, grow," said the equine blushing just a little bit.

"Yeah but they shouldn't even be able to do- Ohhhh!" gasped the gecko as a sudden deep tingling started in her breasts. Her paws quickly shot to the thick pair of nipples that capped her chest as she felt the pair begin to expand.

"Ohhhhhh Gawwddddsss," whimpered Helena as the mammary issue within her tits began to expand after being forcibly pumped full of the hyperactive nanites. It was a slightly different feeling from when her muscles grew but still pleasurable as she ran her paws over her mounds. They were now slightly softer that before which was odd as she continued to palm them. Other than being slightly larger and softer they weren't much different as Helena cooed and pondered just what was going on. Coaxed by the nanobot's the expanded mammary issue in the gecko's chest rapidly began to produce milk as her eyes widened. Slightly purple tinged milk was dripping though her fingers as it flowed from her swollen nipples. Within seconds her limited internal capacity was full as the pressure within her chest turned into a pleasurable ache while her beachball sized jugs began to swell again.

"Nnngggg! I-I'm lactating!" hissed the gecko as she slipped a milk coated finger into her maw. The strange almost purple milk had a taste that she was familiar with as she realized that her milk appeared to be laced with what seemed to be Ubertrex. The sensations drove her paws back to her tits which kept growing as they hefted themselves even higher on her chest and firmed up even further. Her body quickly took notice of the new source of Ubertrex as the excess milk not able to escape from her leaking teats was reabsorbed back into her body. No longer in need of an external source of Ubertrex, the gecko's body now produced its own supply as the steroid was rushed to her waiting muscles.

"Oh fuck yes," growled Helena as she flexed her arms and the steroid flowed into them. The gigantic peaks of her biceps suddenly swelled larger while the rest of her chest continued to grow. Her breasts at last stopped growing when they were nearly twice the size they had been before. Blake released that her new size was going to cause a significant blind spot in her peripheral vision but he couldn't argue with the results as he ogled her gravity defying chest.

Ubertrex continued to pound through her veins as Helena soaked it all in. Her shoulders grew as her neck and traps thickened but nothing seemed to grow at the rate her biceps did. Larger than basketballs, the hulking masses seemed to grow thicker and stonger with each flex while her forearms did the same thing. It was a seemingly never ending series of flexing and growing and flexing and growing as the massive reptile roared her approval. When at last her body could hold not another pound without busting the flow of milk from her breasts diminished to a slow trickle just enough to keep her at her current size.

She came out of her growth induced haze as she looked at the parts of her figure she could see. The squeal of delight that came out of her made Blake jump as the colossal gecko ran over to the mirrored platform she had built. She hopped on it as the metal groaned and projected a number onto the glass in front of her.

"2077 pounds! I'm over a ton!" said the ecstatic lizard as she admired her reflection. Never before had she been so captivated by the way she looked. Every part over her looked pumped beyond her wildest dreams as she grunted and hit a most muscular. The nanobots were absolutely the best thing that had happened to her since she had invented Ubertrex and now they had freed her from having to use her steroid pump to reach her maximum size. Her entire body rippled with power as she bounced each breast and watched Blake's lust filled eyes glaze over.

The stallion's sizeable flagpole was standing straight out in front of him and had been since the gecko started growing. Something about all that sexy power in one package simply did it for him as she turned and gave him a predatory look that made him whimper.

Helena grinned as she strutted towards the lust struck stud. Her paws went to his shoulders as she gently lowered him to the ground and hovered over him on her hands and knees. Blake swallowed hard as he stared up at the literal ton of horny gecko on top of him. The entrance to her glistening folds was a hairsbreadth away from the spade shaped tip of his cock as the smell of honry she-lizard washed over him.

"Still up for that bit for that bit of fun I talked about earlier," she whispered in a hurried raspy tone.

"Oh gods yes," said the horse as Helena churred and moved her lower body just a fraction dragging her puffy pussy lips across his tip. Blake felt her folds wink around him as he groaned and let out a heated snort. His hips bucked upward but were stopped by a large paw on his abdomen which held him back effortlessly.

"Now now, we're going to do this at my speed," she said as she began to lower herself onto the twitching horse. Helena was wetter than a boat in a storm but she still had to relax to Blake inside her. He was a big horse but she was an even bigger girl as she kept going, taking more and more of the studs steely length.

Blake was in heaven as he felt his cock disappear into the tightest, wettest, hottest fem he had ever been inside. He could feel the gecko's powerful quim squeezing and rippling around his shaft until an entire foot of horseflesh was throbbing within her. If the expression on her face told Blake anything she was enjoying it just as much as him as her muzzle darted downward and pried his lips apart for a kiss.

They feasted on each other's muzzles as she worked his cock out of her body before sliding down his length again. Their pace increased as Helena did all the work with her hips while gently holding her bucking steed down.

Blake could feel the strength in her paws and see his partner's giant body flexing and tensing with each movement. It turned the horse on more than he thought possible as she increased to a jackrabbit pace. Something that huge shouldn't have been as fast and as nimble as she was, but the stud couldn't think about that as he concentrated on not cumming.

"A hard man you are!" growled Helena as she began working a swing into her thrusts and ridding the poor horse forward and back on each trip up and down his cock. Blake nickered and snorted as his body clenched tight but he managed to hang on as the gecko brought him into another kiss.

Helena was enjoying her little session more than she could have imagined thanks to her new nano sized passengers and the overhaul they had performed on her nervous system. The sense of touch they gave her was frankly amazing, and she could feel even the minutest details of Blake's cock as it slid in and out of her. Every bump, every ridge, and every throbbing vein was recorded in prefect detail and transmitted directly to her brain which meant she was cumming almost every other thrust, only she wasn't. Her level of muscle control was now so fine that she could wrest back control over her body during the event or turn her sensitivity up or down at will. She had yet to throw the switch all the way to its maximum and had already decided to do so when the stubborn horse at last let go. In order to help him along one of her paws moved behind his head and forced the stallion's maw onto her quivering teats.

Like a good boy, Blake latched on and began to suck for all he was worth as the gecko's groin grew flush with his. He was frankly proud of himself for lasting this long as he cried out around the thick nipple in his mouth. The stallion's cock head flared as cum shot up his shaft and exploded deep into the waiting reptile. The she lizard could feel his warmth painting her insides as she turned the sensitivity of her netherbits up to eleven and began to fry her mind.

Blake felt two arms grab him and suddenly he was on top of a thrashing she-beast as she rode out the biggest climax of her life. Her pussy clamped down so hard around his rod Blake thought for a moment that it might break off before his mouth was flooded with milk. He reflexively swallowed as a warm feeling seemed to grip his body as he felt his on climax tapering off. His mouth stayed busy however as the flow of milk into his belly increased while the big gecko writhed beneath him.

Everything seemed to go white as Helena let loose and allowed the pleasure she was feeling to overtake her. Orgasmic sensations crashed against her like waves one after another as she rolled onto her back. It seemed to go on forever until she felt the sensation of a hungry muzzle on to one of her nipples sucking as the Ubertrex filled milk flowed right out of her. The feeling seemed to extend her cataclysmic climax even longer till at last she came to still shivering as Blake's paws kneaded at the huge milkbag he was drinking from.

The hungry stallion seemed to grow thirstier by the minute as the flow of milk into his body kept increasing, and it was beginning to have an effect. His muscles were bulging everywhere stretching his hide tight across his body as he kept on growing and Helena's critical eye estimated that the horse had already packed on forty additional pounds of brawn. The high protein milk and super pure form of Ubertrex were also having a profound effect on Blake's libido as the emerging muscle hoss gripped his resurgent cock with both hands.

Acting as if he hadn't just cum, the randy stallion plunged back inside the still quivering gecko. She moaned under him still pretty much unable to move thanks to the aftershocks of the climax she had just experienced and could do little as Blake's thrusts grew harder and rougher.

Blake had never felt so good in his life as his body seemed to burn with power. The stud's muscles all seemed to bloom while his lust grew hotter and hotter. He was fucking the lizard beneath him faster than he should have been able while his mouth remained attached Helena's thick nipple. Despite him sucking harder the flow seemed to slow as one of the gecko's paws grabbed him by the mane. He let out an angry snort as he was pulled off one breast only to be placed on the other as his hungry muzzle went back to work.

His growth fueled fucking was driving the big gecko mad as the stallion continued to pound away. It seemed that as long as Blake was slurping away at her milk, Helena had her very own tireless sex toy. The though led to another devious idea as she closed her eyes and began to concentrate giving the nanobots in her body some very specific instructions.

In his near feral state of lust Blake barely noticed it when a warm tingle seeped through his cock. If anything it made him pump faster as the virus sized nanobots made the jump from Helena's body to his. Soon he had a sizable collection with his shaft as Helena sent them a few choice commands. The industrious robots soon went to work expanding the network of blood vessels and tissues inside his shaft. It didn't take Blake long to notice something was different as a tightness seemed to grip his colt maker and his entire tool seemed to thicken making his thrusts slow to a crawl.

Bake looked up at Helena's grinning face with surprise as his cock gave another heavy throb and stretched several centimeters further into the gecko's clenching sex. One powerful paw gripped the back on the studs head and the other grabbed half of his rump as Helena laughed and shoved him balls deep while pressing his head further into her mountainous tit.

"Time to pump you up horse!" she growled as the massive lizard flexed her entire upper body and commanded her nanobot army to flood her with milk. The pressure inside her chest spiked as Helena let out one long low moan and felt her already beach ball sized mounds swelled and firmed further. Blake suddenly had quite the mouthful on his hands as he struggled with the sudden increase in flow. The fresh flow of Ubertrex and nano infused milk was even more potent this time as the studs eyes began to glaze over again while Helena watched as his muscles continued to twitch and grow.

His hips began to move as the nanobots continued to enlarge his already prodigious member pushing it past fourteen inches while the gecko's paw continued to drive their bodies against each other. Thrust by thrust the horse seemed to grow stronger, his hips rocking harder against the geko's body as Helena's paw moved further up the stallion's back. She could feel and see the horse's physique transforming further as sinew and brawn rippled and bulged under her fingers.

Blake felt alive and virile like he never had before as his whole body shook with might. The stallion's already thick quads gorged on ubertrex as his thrusts grew steadily stronger. The equines tail lashed back and forth against a muscled rump that was growing steadily larger as Helena squeezed hard enough to make the horse wince.

The stallions biceps bulged as he wrapped both arms around one of the gecko's beach sized breasts and squeezed. The super firm teat barely moved as Helena trilled with pleasure and Blake was rewarded as his mouth was flooded with an even heavier wave of cream. Not a drop was spilled as the stud gulped it down like a starving man. Not content to let him have all the fun, Helena sent a message to her tiny mechanical friends inside Blake's body as she shifted her free hand until both were filled with horse rump.

Blake's cock slammed home as his rump flexed and kept flexing as it grew even thicker to fully fill Helena's big paws. She squeezed again drawing another moan from the stallion as another part of him grew again. The sensation of his member growing inside the clenching gecko was too much for the overheated horse as he erupted inside the roaring fem beneath him. His mouth came off her swollen nipple as his arms snapped to her waist just to keep himself from falling over.

His cock flared and then seemed to flare again as his whole member thickened and stretched another several inches into the quivering gecko's tunnel making the muscle bound lizard howl with delight. Meanwhile a fresh wave of stallion seed rolled down his shaft as he attempted to fill up Helena's womb. It was more than Blake had ever come in his life as he let out a mighty whinny. Every muscle on his body stood out in stark relief and to Helena it looked like the horse had picked up a good two hundred pounds of brawn as he continued to spew like a geyser.

His production was in large part down to the millions of nanobots populating his steadily swelling balls which were now the size of healthy grapefruits. The nanobots were also spiking his testoerone levels through the roof as he at last finished with a fiery snort. Helena looked flushed her scales slick with sweat as she purred and grinned up at the stud.

"Ready for round two?" she growled as she hefted her other tit and a pearl of milk beaded of the tip of her swollen nipple. Blake's still hard cock throbbed deep inside her as the stallion drove himself forward hard enough to rock even Helena's heavy body. She cooed as his lips latched on to the leaking pink bud and his groin slammed home into her swollen clit.

Almost reluctantly he pulled out of her as his muzzle came off her nipple and motioned for her to roll over. Helena caught on quickly as she went to all fours and raised her trunk like tail high. Her tits were so large that her nipples rubbed against the floor as she wiggled her muscular rump and looked back at the stud over one shoulder.

Blake was momentarily stunned by the view in front of him and the jaw dropping new size of his own endowment. He had always been rather well hung but now he sported a veiny monster that was much closer to two feet than one. It also didn't seem to be finished growing as finger sized veins fought for space and visibly throbbed with each beat of his heart. His cockhead was so wide he looked permanently flared and he briefly wondered where the gecko had managed to fit all this. His thoughts were quickly forgotten as his tip began to rub his partners thick velvety folds.

Helena was dripping a mixture of her own juices and some of his cum as she felt the horse slowly grind his cockhead against her. The hulking she-lizard had to bite her lip and muffle a growl as he at last pushed forward and spilt her swollen vulva wide open. Blake's size was putting him in very rarified air as Helena paged the nanobots in his body to keep growing the glorious horse cock that was stirring her insides. She felt one of his arms wrap around her upraised tail while the other gave her ass a nice hard slap as he thrust all the way home.

Blake nearly lost it when he heard the sounds that coming from the gecko's mouth as his hips started going. Helena was so big than even on her hands and knees she was just the right height to be pounded silly as her arms stared to shake. He felt her cum around him as her snatch clamped down and a new wave a strength seemed to roll over his body. Blake let out a masculine roar as his muscles rippled and grew, gorging further on all the Ubertrex he had consumed.

His package received the lion's share of the growth as his balls went from coconut to melon sized, and his cock smashed past the two foot mark as he stretched Helena to her limit. A barely sane lizard sent one more command to the rutting beast behind her as Blake's lower body trembled and grew again. The nano-bots threw all their resources into bulking up the stallions already powerful legs and rump to give him even more thrusting power as both Helena's paws flew to her throbbing clit.

With his new found strength Blake began to set a blistering pace, sawing in and out of the massive she-lizard while she fingered herself. Her massive muscle tits were big enough to keep her back mostly straight as her weight pressed them into the floor. Purple tinged milk continued to leak from a pair of impossibly erect nipples while Blake continued to pound her insides flat. Ever the masochist the, geko's paws moved to pinch both her nipples shut cutting off the flow and making them swell again. The added pressure inside her globe like jugs make them firm enough to where they refused to flatten out under her body weight as their slowly expanding size began to push her higher. The strain on her chest brought about a pleasurable ache as more and more veins popped to the surface of her muscle tits while they continued to grow ever larger.

Blake soon noticed that Helena was slowly rising as her voluminous chest continued to grow each time he plunged into her depths. The idea that he was making the massively swollen lizard grow even more lit a fire under him and the randy stud redoubled his efforts.

Helena's mouth hung open as she tried to focus through the waves of bliss that crashed against her body in an endless stream. She couldn't focus enough to turn her body's sensitivity down and didn't really want too as the pressure inside her chest kept climbing. Her breasts where almost prefect spheres now with only her nipples touching the floor while her fingers kept a death grip on them. She was squeezing so hard it hurt but the feeling of her tits being forced ever larger was making her gush around Blake's thick tool. The stud's cum heavy balls smacked her engorged cit just right each time he slammed home as more and more of the purple milk began to slip out from between her clenched fingers.

"MMMM YES PUMP ME UP BIGGER! BIGGER!" roared the near delirious geko as Blake hilted himself and fired round after round of hot horse spunk into her womb. The sensation of him filling her up combined with the pressure now beanbag sized muscle tits was too much as Helena's body twitched and her fingers came off her turgid nipples.

Twin high pressure jets of gecko milk blasted the floor hard enough to crack the tile as Helena experienced her first nipplegasm. Her whole chest clenched and began forcing all her surplus milk out flooding the floor around them and making the she lizard's mind go hazy with pleasure. She couldn't help but grab as much of her chest and squeeze as her nipples fired off wave after wave of Ubertrex laced milk while Blake continued to pump her full of his own cream. It was the most delicious sensation the jaded reptile had ever experienced as she felt her partner give out just before the last few drops trickled out of her teats.

Unsure if it her orgasm had lasted five minutes or twenty, she felt Blake collapse on top of her back as his semi-hard member slowly slipped out of her sex. She quickly caught the exhausted equine before slowly standing up and cradling him against her now smaller chest. Force inflating them with her own milk appeared to have had quite an effect since now they looked noticeably larger and quite a bit more vascular than they had before. Her nipples also looked noticeably larger and were the same vivid shade of purple her Ubertrex filled milk was. Both her muscle tits seemed to fade from the normal light green of her under belly to a more purplish color as you got closer to her nips which added an interesting contrast as she viewed herself in the mirror.

The tired stud in her arms had also been though his own transformation as she looked down at his thickly muscled form. His legs were massive and outsized the rest of him making him slightly out of proportion but Helena would fix that as she brought his muzzle up to one of her teats. With a sleepy mumble the horse's lips quickly wrapped around the fleshy cap as the gecko opened the taps again just a bit to give him the calories he needed to grow even bigger and stronger.

His gentle sucking made her coo and shiver as she took the steps up towards the first floor. The now hungry gecko grabbed a full six pack of her calorie packed energy drinks and polished off two before she even left the kitchen. Still holding Blake in one thick arm the gecko moved into her bed room her shoulders brushing every doorway she didn't go through sideways. She finished off another shake before stepping into her bedroom shower and rinsing the both of them off.

Blake, more asleep than he was awake, never once stopped nursing until Helena slowly but them both into her massive bed. His head ended up between the gecko's massive breasts as the reclining reptile sent a message to the nanobot's swimming around the horse's body. By morning his upper body would be proportional with his lower and his body weight would be almost doubled. Not bad for one day's work as Helena slowly ran a paw up his chest. He was too tired to do anything but snuggle up closer as she let out a long slow breath.

Her own body needed time to recover as well as she felt her muscles go into their recovery cycle. There was only one thing left to do before bed....

Lily the CEO of Sherex was reclining in hir cave like den as the warm fire behind hir bathed hir brown scales with warmth. One off Lily's tendrils played slowly over hir semi-hard cock as the t-rex's pondered on what to do for this evening's entertainment. There was always hookers and blow, perhaps some VR porn, or maybe just a cigar or two while shi let hir tentacles ease the pressure in hir over full balls.

Hir phone hummed as shi picked it up with one clawed paw and saw that it was from Helena. The gecko was a girl after hir own heart as Lilly's cock stood up straighter. The T-rex pressed a finger to the screen as a picture of the Gecko on her bed greeted her. Even laying down the flex Helena was holding in the pic make Lilly salivate as hir eyes roamed the rolling expanse of her employee's body.

Lilly's cock went ridged as several more tendrils joined the one already there while a few others began to tease hir folds. She had never seen anyone so huge! So massively pumped! So utterly swollen with might they might explode if they flexed any harder! Lilly was a walking encyclopedia of fetishes and was quite huge herself but Helena had taken it to another league. She had the lust for muscle in quantities that made even the t-rex blush. The gecko's hugeness and her dedication to making herself that way make the t-rex moist as hir cock dribbled pre onto the floor

The phone in Lilly's orange scaled paw beeped again as a fresh picture appeared. The sight of it promptly made Lilly cum with a roar as her eyes feasted on the screen. Helena's long tongue was wrapped around one of her huge nipples as she slowly lapped what looked like milk from her own tit as the t-rex's cock shot streamer after streamer of pearly white cum clear across the room.

When the shi rex was able to at last calm down and read the read the text on the screen shi smiled to hirself and let out a low chuckle. The nanobots had been a complete success and now the t-rex was itching to try some. Hir muscles flexed and clenched at the idea of all that power as the leather chair underneath the massive herm creaked. Tomorrow was Saturday so perhaps she ought to pay her favorite employee and her new stud a visit...
