Scientific Progress By Theo Winters

Written for Ghost Blackburn

The tubby lion walked through the lobby of the research lab, his heavy belly swaying from side to side with each step he took. It bounced between his four legs in time with his rolling gate, his tail swaying quickly from side to side to balance his weight. As odd as this should have been, no one else in the lobby seemed to care about a wild lion was in their midst.

He walked up to the front desk, his tail flicking out as he dropped down to sit on his wide ass. Lifting his head up, he licked his lips and looked at the cheetah woman sitting behind the desk. "I'm here to see Mr. Winters," he said, his voice deep and rumbling through his large body.

"Of course Mr. Blackburn," she said with a knowing smile, hardly phased by the fact that the fat lion could talk.

The lion nodded and didn't move from where he sat, his tail flicking against his rump in anticipation. He was eager to find out what his mad scientist friend had in store for him. In the past the crazy man had played around with impossible technology and weird magical hybrids. The majority of the time it made being a test subject very enjoyable.

Without thinking about it, he reached up and stroked his paw through his snow white mane, teasing it with his blunted claws. The last time he had come to visit he had found himself turned into a lioness, much to his own surprise. The time before that involved fruit flavored gum and ended up with him needed to be juiced. He looked back fondly on both of the incidents.

The cheetah smiled down at him. "Okay, Ghost, you can go back to see him," she said, buzzing open the door.

"Thank you, Felicia," he replied, hefting himself up onto all four legs. The large feral lion walked past the front desk and pushed open the thick steel door with his shoulder. It moved easily, even though it weighed a few tons, swinging open for him and then swaying back until it closed with a heavy thud that echoed down the hall. He padded down the hallway, passing some of the other staff as he headed towards the largest lab in the very back. The whole place was basically a collection of mad scientists of various types which led to things like the giant gerbil that made his home in the break room. They weren't all mad as such, in fact most of them were just eccentric and had a reckless disregard for safety. Even so they were very interesting and quite a bit of fun to work with.

Ghost walked up to the last door in the hallway, rapping on it with the tips of his claws. A moment later it swung open to reveal another heavy set lion. This one was standing upright, wearing a green t-shirt and jeans under a long lab coat. He looked down at the fat feral lion through his small glasses and gave him a smile. "I was wondering when you were going to get here."

"The subway wasn't too happy to see a lion," he replied, walking into the lab with his head held high and his tail swaying from side to side. "So, what do you have for me this time, Theo?"

"Oh, something that should be quite fun," the other lion replied with a chuckle, adjusting his glasses a bit as he closed the door, after that he walked through the various experiments to the far wall. It was dominated by a huge reinforced window and another heavy steel door. He sat at a desk by the window and brought up a holographic display and keyboard, typing quickly on the air.

Ghost walked around the lab, purring softly to himself as he looked over all the experiments. Most of them were in a half finished state, but a few looked like they might have been ready to test. He wondered which one it was going to be. Maybe it would be an update of one of the previous experiments, that always had the promise of a great deal of fun.

Finally he moved up to stand next to his friend. "So, what exactly will I be testing, or are you going to tease me about it?"

Theo chuckled and typed away on his insubstantial keyboard. "I was considering teasing you about it, but I'll be honest... I'm not quite sure what this one is going to do. I do have a few ideas about what it should be doing, but only ideas. So this is going to be fun for both of us, don't you think?"

"Not even a hint?"

"Not even a hint," the scientists replied, picking up a small tin from the work surface and giving it a shake. Something rattled around inside the tin, making small clinking noises. "This should take a few days to test, if you're interesting in giving it a try."

The feral lion nodded his head, purring softly.

"Fantastic," Theo replied, standing up and pulling at the edge of his lab coat. He carried the tin in one hand as he walked over to the large steel door and punched a code into the lock. There was deep thump as the locks opened and the door swung open, reveling the way inside the test chamber.

Ghost walked through the door, smirking a bit as his bright blue eyes twinkled in excitement. The doorway was narrow enough that it brushed against the curve of his belly and his wide hips. It wasn't quite enough for him to get stuck, more the pity. The test chamber was a plain room, with smooth white walls and floor, the only thing that broke up the walls was the door and large window. He walked to the center of the room and turned around before sitting down, his ass landing with a thud.

The other lion walked in and popped open the small tin. He pulled out a small black pill and held it gently between his fingers. "Open up," he said.

He did as he was told, and Theo gently placed it in the fat feline's mouth. With a flick of his tongue he swallowed the pill, though it was so small that he couldn't even feeling it slide down his throat. The only sign that it had even been there was a slight chalky taste at the back of his throat. A few moments later he could feel it in his belly, warm and tingling a bit. It churned and made him slight belch which was followed a moment later by a second, much heavier belch that made his belly jiggle against his legs. He flicked his ears back and blushed slightly though his white mane.

Theo laughed as he walked back toward the large door. "Well, that was unexpected. I'll have to make a note of that for later," he said, flicking his wrist out and summoning another hologram display.

"What was expected?"

"Some growth, at least that should be the case. It will be fine, as long as you don't explode from it."

That caused the fat lion to let out a startled belch. "Explode?" he asked as he took in another breath.

That made the lion laugh as he pulled on the edge of his lab coat. "If you wanted safety you should have gone to a sane scientist!" With that declaration he stepped out of the room, the heavy door swinging closed behind him. It slammed into place with a loud bag, followed a few moments later by a series of thuds as the locks engaged.

Ghost shook his head and flopped down onto his side in the middle of the test chamber. He rubbed his large belly with one forepaw, teasing the soft fur with the tips of his claws. "Maybe you'll get bigger," he said to his belly. He was a big lion, but that wasn't a down side to him. He had worked had to get to his current size, and being so large felt very good! His mad friend had promised to come up with some way to make him super fat, but so far there hadn't been any luck in that regard. He kept rubbing his belly, purring softly, hoping this would be the time he got really fat. Heavy enough that he couldn't get back through the door... or at least the main door. He knew that the ceiling could be opened if necessary thanks to the the time he was inflated like a blimp... and to the size of one as well.

A warm buzzing feeling started to form in his belly, deep inside his stomach and radiating outwards. He started to knead the soft fat with his forepaws, his purring growing deeper. The feeling was strange, but it also felt very good. The warmth was spreading out over his belly and along his chest, then finally down all four of his legs.

Ghost kept kneading more of his belly, letting out another huge belch, but this one ran through the length of his body, the warmth following just behind it. He could feel it filling his whole body, flooding through his girth and eventually rushing down his tail, the white tuft puffing out. The warmth was everywhere, covering his whole body, but it was starting to spread over his shaft and balls and making him twitch inside of the sheath. It was a very nice feeling, one that made him start purring again as his tail began to twitch slowly across the floor.

The big lion let out a low moan as the warmth grew stronger in his most private of areas. He found himself smiling and stretching out his hind legs, feeling his body pull as the pleasure grew and shaft starting to swell outwards, the pointed tip peaking out of his sheath.

"How do you feel?" Theo's voice asked over the PA.

"Gooood," he replied, flicking his tail up between his legs to rub the tuft over his balls, teasing it with the white hair. The warmth seemed to be growing stronger though his balls, more of his shaft slipping free from his sheath. Licking his jaws he rolled onto his back, his belly sinking down over him and his swelling penis rubbing against the fat. He returned his forepaws to kneading the soft surface while continuing to tease his tail over his balls.

By now, he had no idea what exactly what this experiment was going to do to him, but he was enjoying it so far. Chuffing deeply he kept teasing himself with his tail, sliding up to stroke along his shaft. The warmth was spreading out across his back, the fur tingling where it touched the floor.

He let out another long moan, whimpering softly and curling his toes as his shaft reached his full length. He was nicely sized, especially for a feral lion, the pointed head rubbing up against the curve of his belly and starting to dribble pre. Dropping his tail down, he wrapped it around his large balls, cupping and squeezing them gently as he teased his shaft with the tuft. The warmth was growing stronger by the moment, radiating out from his balls to fill his whole body.

The lion started to stroke his tail along the length of his shaft while at the same time rubbing the head of it up against the curve of his belly. He pressed his forepaws into his stomach, sinking them deeply into the soft surface and started to jiggle it in place. There was enough give to his belly that it started to rub up against his cock, teasing it even more.

Ghost let out a low growling moan that was mixed with a deep chuff. He was enjoying the feeling of this strange pleasure that was filling his balls. The warmth was so strong now that it was almost enough to get him off on its own. He squirmed in place, rolling his head back and lolling his tongue out of the side of his muzzle, his tail working to tease his shaft even more as his arousal grew with each passing moment.

He kept working his tail against his shaft, stroking the tuft along the length of it and teasing the spines around the tip. Precum was soaking the fur on his belly and starting to roll down his sides and soak his tail. It provided some nice lubrication as he continued to stroke and tease himself.

The fat lion started to rock from side to side, pressing his ears down into his white mane as he rubbed the side of his tongue against his fangs. He squeezed at his belly, kneading his paws over it and rocking it down against his cock while his tail teased it even more. He squeezed it around his balls, feeling the warmth flair through him and making him tightly curl up his toes, squeezing his claws against his smooth paw pads.

Then without warning his climax crashed down over him, breaking across his body like a wave. It washed over him, filling him in moments before exploding out of him and into the air. He let out a roar, squeezing his balls as he came. He could feel his shaft swelling as cum shoot down the length of it and blasted out from the tip too spray over his belly. The climax was nothing like he had ever felt before, it was incredibly strong and growing stronger by the moment, causing him to roar a second time as more hot lion seed gushed out of his cock. In a few moments it felt like he had cum as much as he would have in a week, yet it was still coming and getting more intense by the moment.

Ghost rocked from side to side on his back, his orgasm showing no signs of abating. Instead there was a constant stream of cum spraying against the curve of his belly, the line of his urethra was swollen outwards from the pressure, pulsing against his tail. The pressure from his orgasm was sending a spray of lion cum up into the air to rain down as a fine mist over everything in the room.

Still his climax was not slowing down, wave after wave of seed was rushing down the length of his shaft. He could feel his testicals churning in his sack, squeezing as they were emptied out before swelling outwards as they almost instantly refilled. It was making them throb in pleasure, which just added to his ongoing orgasm. He rocked and whimpered, squeezing his tail around his shaft, stroking along the length of it. By now the lion's fur had been soaked with his cum and it covered his lower belly and his hind legs. With a twist of his tail he pulled his shaft up, sending the jet of cum arching over his gut to splatter onto his face, soaking his mane in an instant.

With a purr, the big lion opened his mouth wide, allowing the jet of hot seed to land on his tongue, filling his mouth in a moment. It was thicker then he remembered it being, but it tasted wonderful, sweet with a hint of something else under it. He couldn't quite place the flavor, but it was a very pleasant combination.

He closed his mouth and swallowed down the hot cum, which only caused more of it to spray against his face. With a snort of air, he cleared the semen out of his nose and opened his mouth to capture another load. By now every part of him was covered in his cum, it was dripping down his belly and rolling off his fur even as he continued to cum. A puddle of seed was starting to gather around him on the floor, and it was growing larger by the moment.

Ghost let out a soft cry, the pleasure growing even stronger as did the warmth in his shaft. His balls were churning and throbbing, putting out more and more cum by the moment. It added to the pool around him, which as starting to near the walls of the chamber. He turned his head to the side, shaking off the cum that had covered it and looked back through the window, seeing the scientist standing in place and watching with a look of glee.

"How are you feeling? Is it too much for you?" Theo asked, smirking a bit, one hand was hidden under the work table, but it was easy to guess what he was doing with it.

The fat lion licked the cum from his face, trying to keep it clear but finding it wasn't easy. Finally he had to roll onto his side, using his tail to point his shaft towards the floor. "It feels very good," he said, watching as the semen arched out from his cock to spray across the floor with enough force to nearly reach the wall. By now the floor was covered in a thin layer of cum, which was growing thicker by the moment.

"So good," he added with a whimper, rocking in place before rolling over onto his belly, pinning his jetting shaft under his own bulk. He could feel his cock twitching under his girth, pulsing against his fat with each jet of cum. The weight of his body pressing down onto his balls seemed to increase the force of his orgasm, even more of semen washing out from under him and across the floor.

As good as that felt, he couldn't stay laying on his cock while he kept cumming, so instead he forced himself up onto all fours, though that wasn't enough to lift his belly out of the line of fire from his cock. By now there was an inch of cum on the floor of the test chamber, and it was rising up higher around his paws.

The pleasure from the orgasm was making his head spin in a very pleasant way, but at the same time the pleasure had become such a constant that it was almost losing all meaning. It filled his body and his mind, making him whimper out in pleasure and thrust his shaft against his belly, his tail dropping down to splash through the pool under him. His orgasm was getting so strong he felt like he was going to cum out his balls.

His legs were shaking from how good the constant orgasm felt, his paws starting to slip in the thick sticky cum. With a yelp his forepaws went in different directions and his ass slammed down into the pool, sending a wave of it crashing accost the room to splash against the wall and up over the window. He grunted and tired to struggle back to his feet only to have them slide out from under him again, this time he ended up landing face first in the semen, which rushed into his mouth and even up his nose.

Ghost lifted up his and shook it, thick globs of cum flying from his mane to splatter over the walls of the test chamber. He followed that with a heavy snort to clear out his nose and then tried to wipe his face clean, but it did nothing to help. Finally he pulled himself back up to his feet, surprised to see that his constant climax had filled the room to the point that it was lapping over the top of his paws.

The fat lion lapped his tongue across his face, licking it clean. The taste of the cum had changed, but it had gotten even thicker, it also made it much easier to enjoy the flavor. He lowered his head down and lapped at the cum, flicking it up into his muzzle as he started to purr at the taste. He had always wondered what it would feel like to bath in a huge load, but he had never thought he would get the chance to do so.

His climax continued to rush over him and the level of semen in the room continued to rise, starting to lap against the bottom of his belly, more and more blasting free of his cock. The pool was at least six inches deep now and was growing deeper as he watched. The pressure was throbbing along his shaft as his orgasm continued unabated, his balls feeling huge in his sack, pulsing with pleasure. He flicked his tail down to rub at them, feeling the tight skin as the heavy orbs pushed out gallons of cum by the minute.

He let out a soft whimper, the pleasure was becoming too much for him, no matter how good it felt. The constant flow of cum was rushing down his shaft like it was a fire hose, spraying over his belly and into the pool around him. There didn't seem to be any sign that his orgasm was coming to an end, or if it ever would. For a moment he had an image of drowning in a room full of his own cum, which really wasn't that bad of a way to go, but it was too early in the day for that.

Carefully he made his way across the room towards the window, making sure of his footing with each step he took. He looked up at Theo through the glass, the other lion was watching with a smile on his face, making notes with one hand. By the time Ghost had made it to the wall the pool of cum was almost to his knees.

"I like this one," the fat lion said, purring deeply and shifting his tail over the surface of the sticky pool, letting it soak into his fur and making it look just as white as his tail tuft.

"So do I," the scientist replied over the intercom, chuckling softly to himself.

The big lion nodded and pressed his nose up against the glass while smiling at his crazy friend. "Now, how do we stop it?"

"Stop it?" the lion asked, saying the words like it was the first time he had even thought of the question. His ears perked up a bit and he rubbed his chin with one paw. "Stop it?" he mused, looking slightly befuddled by the very idea of it. "Well, I suppose that it wouldn't be that hard to neutralize the nanogenes, at least in theory. They really aren't that easy to program, but I'm sure we could come up with something. It should only take a few weeks..."

That made Ghost laugh, that was always the way with the insane lion. "I'll be floating in half an hour."

Theo paused at that, rubbing his chin again. "I don't think that would be a very good outcome to this experiment... that and I don't have a clone ready to be decantered. Still, I would rather not fill the room, the drainage wouldn't be able to keep up with your output. I might be able to do a quick short circuit of the programming."

"Well, don't take too long," the fat lion replied, dropping his down into the deep pool of cum and sending a wave of it rolling up over his back and across his head. The pressure was still growing in his shaft, and while it still felt good, it was becoming rather uncomfortable. He churning his tail through the semen, the tip bobbing along the top like a shark fin.

On the other side of the glass Theo had pulled out his holographic computer and was typing away. At the same time he was purring loud enough that it was echoing through the glass of the window. Ghost watched him, feeling the level of cum rising up higher with each passing moment. Even with how large the pool was, it was still warm and rather pleasant as it lapped against his belly and sides.

The room smelled of his heavy musk, so thick he could almost taste it on his tongue. "Where is all of this cum coming from?"

"Your balls," the lion replied, only pausing long enough to give the fat lion a bit of a look.

Ghost laughed and shook out his mane. "I know that, but how can I be producing so much of it?"

"Oh, that's easy. The nanogenes are using lepton level Feynman-Zeilinger matter transmission to gather stray elements from the curst of the Earth... or another Earth, I'm not completely sure about that part but it's not that really that important. The various elements, including hydrogen, carbon and nitrogen are used as raw material for protein chains which then are fed into your testicals. The nanogenes stimulate them to force rapid production and improve a few things to increase the flow. Your body could produce quite a bit more but other physical properties limit them."

The fat lion cocked his head as he tried to understand his friend, who looked so happy at his explanation. Some of it made sense, at least as words, but the rest of it was over his head. Still, he seemed to believe what he was saying, and when it came to mad-science that was really all that mattered.

"Well, I believe this should resolve some of the issues," Theo said as he adjusted his glasses and smiling with pride. He turned away from the window and did something with the equipment in the lab. "I'm going to have to use a more direct approach with administering it," he said as he turned back, fiddling with something just out of view.

"And what's that?"

Theo turned back to the window, smiling a bit. "You'll see," he said. A moment later there was a soft clunk from above. The fat lion craned his head up to see an open panel in the ceiling, the barrel of what could be a gun was tracking across the room towards him. He was about to object to it when it fired at him, a black dart smack hard into his flank, making him jump in the pool of cum.

He snapped his head around to bite the dart, pulling it out of his flank and spitting it towards the window. "Was that necessary?" he asked, flexing his hip, the impacted hip felt warm, the fur standing on end.

"Unfortunately yes, there's no way into the room unless it's drained. Though I had to dial up the pressure to get through your rather pleasing girth."

The fat lion shook his head, admitting that the crazy scientist had a point. The warmth was spreading across his body, filling him and making him purr. At the same time the pressure in his shaft started to drop as the constant orgasm finally came to an end. Strangely the end of the pleasure itself was actually rather pleasurable, though it leave him feeling a bit empty deep down inside.

Ghost let out a pleased sigh and flopped down onto his belly, laying in the thick pool of cum. "That worked," he said, his tail flicking happily in the pool, sending it swishing around him.

"I'm glad. Now let's see about getting the test chambered drained."

The fat lion nodded and was about to say something else when he felt a rumbling from deep inside of him. It was as strange feeling, not like he was hungry, but something else... and it was growing stronger by the moment. A moment later it was followed by a new feeling in his balls. It was a growing pressure, but not like before, and it was followed by an itchy feeling along the underside of his still hard shaft.

He sat back up and dropped his head down, trying to look at himself but couldn't see anything through the cum. The rumbling was growing stronger now, focused deep inside his balls and making him gasp in surprise. The rumbling starting running up the length of his shaft, all the way to the very tip. The pressure grew and grew, making him shift around uncomfortably.

The pressure kept growing, but it wasn't that bad in fact it was feeling pretty good... which was strange. His cock was pulsing with the strange pressure, rubbing up against the curve of his belly, sliding further along it with each passing moment. In fact it was pushing further against his belly then it ever had before.

Ghost stood up onto all fours and twisted his body around, trying to get a view of his equipment, but his girth and the cum didn't help at all. With a grunt he flipped onto his back then craned his head up, trying to get a view, but once again his belly conspired against him.

"Are you okay?" Theo asked over the intercom.

"There's something going on with my dick," he said, dropping his head back into the pool.

The scientist grunted a bit, which was followed by the sound of typing. "Huh, it looks like it's growing."

"What?" He asked, lifting his head up to look at the window.

All the other lion did was shrug a bit.

The pressure continued to grow, his shaft rubbing over more and more of his belly, his balls starting to press against his legs and pushing them apart. A moment later he saw the tip of his shaft summit his belly, rising up over the curve and growing higher by the moment. It would have been an impressive site if it had been something he had been expecting. Then again what could he ever expect with Theo?

The fat lion squirmed in the cooling pool of cum, his shaft rising higher over his belly, it was also growing wider. HIs balls were starting to spill over his hind legs, filling all the space between them. The weight was pressing down on him, pinning him to the ground, yet there didn't seem to be any signs of the growth stopping.

"Can you stop it?" he asked, watching the head of his cock as it rose up higher and higher over his belly, thick drops of pre falling from the tip to slash onto his face, soaking into the fur in a moment. It did feel quite good, but it felt out of place. If this was a bit more controlled he would probably be enjoying it more.

A heavy hum filled the room as the floor starting to vibrate under him, a moment later the cum started to drain away. He leaned his head back, looking towards the window to try and see the other lion but there was no sign of him. Looking forward again he was greeted with the site of his cock towering above him, the shaft jutting over the top of his belly and swelling out even longer then his body. The whole length was pulsing with the beating of his heart and growing a little bit bigger each time. It was half as wide as he was now and his balls were growing even faster, pinning his legs against the floor as it covered more and more of his tail.

He reached up with his paws, starting to stroke gently at the shaft, feeling it growing under his pads. Even the light touch sent jolts of pleasure along his length, making it bounce against his belly as more of the precum splashed onto the floor above his head. Slowly he lifted his tail, rubbing his tuft over his heavy balls is a motion that sent another wave of pleasure through his body.

The floor shook again as the pumps turned off, only a few puddles of cum left on the floor though his fur was still coated in it. It was only something the lion noticed in passing, he had more important matters at hand.

He stated to stroke faster as his length, a deep purr growing inside of his fat body as the pleasure grew along with the length of it. It felt so good, no matter what the reason, and that almost overwhelmed everything else. He shifted his hind legs, trying to work them free of his titanic balls, but even just moving them was enough to increase his pleasure.

It was crashing down on Ghost, wave after wave of pleasure washing him away from all of his worries. It just felt too damn good! His paws stroked quickly along the length of his shaft, at least as much as he could reach of it. It was almost as thick as he was and it was still growing! There didn't seem to be any sign of it stopping, and he wasn't sure he wanted it too.

He was shaken from his pleasure by the sound of a number of thumps running through the room, followed by the sound of the thick steel door swinging open. The lion leaned his head back to look at the door and saw Theo walking inside, carefully stepping around the puddles of cum.

"Theo, I need your help," Ghost said, panting heavily. "I can't reached enough of my shaft, can you do it for me?" he asked with a hint of a wine, squeezing his shaft between his paws.

The scientist shook his head as he walked over. "Are you sure that's a good idea?" he asked, getting closer and closer.

"Yes!" he cried out with a whimper, his shaft at least twice the length of his body and still growing.

The other lion paused for a moment, almost like he was thinking it over but whatever response he might have had was interrupted as a huge belch force its way up Ghost's throat, his jaw prying open as the gas rushed forward with enough power to blow the smaller lion a few steps back. His whole body shook from the force of it, the fat of his belly quivering as his massive cock bounced in all directions. The belched seemed to go on and on, lasting well over a minute before coming to an abrupt stop.

Theo shook his head, stepping back forward. "Now that was an unexpected side effect, not quite sure why it would do that."

"Still feels good," the fat lion said with a happy whimper, stroking his cock, though much to his own sadness the growth had finally come to a stop, leaving his shaft incredible huge... but he knew it could be bigger!

"That's important," the mad scientist said as he walked under the shadow of the cock, coming up to the lion and placing a hand on his soft belly. "Still, it was unexpected..." his voice trailed off as he pressed his paws deeper into the lion's gut, sinking in further and further. "Are you getting fatter?"

That brought Ghost up short, dropping his paws from his shaft to rub at his belly. He could feel it growing softer under his touch, pressing out against his paw pads as he grew even heavier. "I am.." he said with a happy chuff, rocking his head back and lolling out his tongue.

With a chuckle, Theo stepped back and starting walking around the fat lion, purring himself as he took in the massive body.

Opening his jaw wide, the well hung lion let out another huge belch, in the process his belly swelling out even faster, the fat spreading out over him as his girth grew, pinning down even tighter to the floor. It was starting to get just uncomfortable enough that he decided to move, at least while he still could.

He started to rock from side to side, using his paws to force his growing belly to sway as well. Soon his huge shaft was getting into it, rocking from side to side as he twisted his body, the motion getting faster with each passing second. Finally he managed to produce enough momentum to pull himself over onto his side, his belly smacking hard onto the floor, his cock hitting the ground a moment later, filling the room with a heavy thud.

Theo ran up to his friend. "Are you okay?" he asked.

The fat lion responded by reaching out, grabbing the lion's lab coat with the tips of his claws. He sank them in and pulled him up against his belly, pinning him between his gut and his shaft. He wrapped his arms around the thin lion and licked him across the face. "I'm fine!" he said, purring happily

"As pleasing as this is, I can't help you here," he said, wiggling to try and get free which only ended up rubbing his back against the tree like shaft, teasing it even more.

Ghost rolled his eyes back, letting out as of long moan of pleasure, his belly swelling out even more as the fat starting to roll up over his sides and down his legs. "I don't mind, just keep doing what you're doing."

Laughing the scientist tried to push away, pressing his paws against the heavy belly. They sunk deep into the warm fat, vanishing half way up to his elbows before feeling any resistance. The blubbery belly rolled and shifted under him, still growing larger with every passing moment. He pulled himself back only to press up against the heavy cock, a stream of precum leaking heavily from the head and running down the length of it.

"Don't stop," the fat lion said, purring happily.

Theo shook his head, trying to push out of the lion's grasp while still laughing. "I'm not trying to do anything!" he said with a smirk, sliding against the soft gut. The lion's already thick legs were swelling out even larger, layer upon layer of fat pile up on them; folds were forming around his knees, even his tail was starting to get thicker as it thumped against the ground in excitement.

"You're going to smother at this rate," the mad scientist said, fighting to get free but starting to purr in time with the big lion. It seemed like even though he was protesting he was still enjoying the experience, though the space between Ghost's belly and cock was getting smaller by the moment. He continued to struggle, starting to work his way free of the girth but it wasn't an easy task.

Ghost wasn't going to have any of that, it felt too good to have the thin lion pressed up against him. He rocked himself to the side, then back towards the other lion, pressing up against him. His growing girth moved like pudding, rippling from side to side before the force of it made him roll over on his belly; pining his shaft, as well as the smaller lion, under his gut.

The fat lion grunted, finding that his paws just touched the ground around his incredibly fat belly. Just enough that he could barely move. He shook his head, dozens of chins shaking under his white mane as he looked down between his legs. His massive cock jutting out under him, the tiny lion peaking out under a fold of fat.

He started to rock on his paws, sliding his shaft over the trapped feline and against his still swelling belly. Rolls of fat were starting to fold over the top of all four paws, this legs getting thicker by the moment. Purring happily he kneaded his paws at the ground, the claws pulling at the steal floor. He shook his tail from side to side as it too grew softer and wide. Soon each time it thumped against the ground it made the floor shake.

Theo struggled under his shaking belly, trying to get free but instead just rubbed at the huge cock, teasing it with his body. His own purring was growing stronger by the moment, the look on his face one of pleasure. He kept struggling with the fat, pushing against it, his arms sinking deeper by the moment.

The titanic lion humped against the floor, as his weight crossed the multi-ton threshold the steel floor creaking under him but still held. That seemed to be the enough for now, his growth coming to a stop. He was slightly bothered by that but didn't care, instead he just used his think tail to rub his car sized balls, teasing each one as he kept humping at the ground.

"I really like these nano-things," he growled, his belly shaking as he started to chuff in pleasure. He kept kneading at the ground, the tips of his paws just scraping against the floor. A moment later he felt his toes pressing against the damp ground, then soon part of his feet.

Blinking in surprise he pulled a paw free, lifting it around his body to look at it. With a purr of pleasure he saw that they were growing larger, swelling out in both size and fat. The pads were getting thicker yet at the same time loosing the rough edge while his whole paws expanded.

"Nice," he said with a pleased grunt, dropping the paw back down to the floor, finding that he was able to comfortable press them on the ground. He kept humping his cock against his belly and the trapped scientist, purring happily as his pleasure grew again. Soon he found himself able to brace his growing paws against the ground, making it easier to fuck the room itself.

Theo pushed at the belly, trying to get free. "I'm glad you're enjoying it!"

"So are you," he said with a laugh, reaching up with one paw to rub the lion's mane, finding that he could easily cover the whole of his head with the paw with no trouble at all. Instead he just teased the lion a bit, rubbing at his mane and face as he kept humping, the pleasure growing stronger by the moment.

Ghost leaned his head down to lick over the smaller lion's face, purring happily as he rocked his body, his tail rubbing and teasing his huge balls, stroking along them as the precum continued to run heavily from his pointed head. The pleasure was amazing but not like before, it wasn't just concentrated on his shaft but instead filled his whole body, his fat tingling with it even as his paws continued to grow larger.

By now Theo had given up on trying to get free, instead he had started working on rubbing up against the lion's belly, teasing the fat with his paws and running his fingers through the white mane and countless chins. "You feel so good," he muttered, pressing his face up against the warm fat.

The fat lion grunted in agreement, rocking faster as his pleasure continued to grow. He started to chuff with each trust against his cock, his balls throbbing in excitement as his shaft twitched under him. With one last thrust, Ghost humped himself hard against his belly and let out an earsplitting roar as he came again. Cum rushed down his shaft and gushed out like a fire hose, hitting the wall of the test chamber with enough force to dent the steel. It felt fantastic, his whole body shaking as he thrust hard against his belly and the ground, flooding the room again in moments. Wave after wave of semen rushed out of him, but unlike the last time he could feel it starting to wane after only a few moments.

Ghost let out a pleased sigh and dropped to the ground, once again resting in a pool of his own cum. He let out a long purr and relaxed off his paws, each one now large enough to be wrap around his cock. "Feels so good," he purred, his eyes closing slightly.

The smaller lion let out his own pleased purr, slowly wiggling his way out of his prison between the fat and softening cock. "I'm glad you liked it," he said as he tumbled out onto the floor and landing in one of the pools of cooling cum. Slowly he pulled himself up and adjusted his lab coat which somehow managed to still be perfectly clean.

He leaned up and rubbed the massive lion on the nose. "I think I would call this a success," he said with a laugh.

"Yeah," Ghost said, licking his nose. Slowly he started to sway his tail against the floor, feeling the three foot thick limb jiggle and shake as it moved from side to side. It felt so good, and soon he felt the familiar warmth returning through his body. His semi-soft shaft starting to swell again.

Rubbing his chin, Theo took a step back. "Huh, that's interesting."

Ghost ignored the comment, sliding his tail up around to start to tease his tail tuft over the curve of his balls. It sent a shiver though his body, his fat rippling across his back as his belly swelled out a little bit more, lifting him another inch off the ground.

Theo took a step back, a smile spreading across his face. He made a show of carefully taking off his glasses and cleaning them on his lab coat before returning then to his muzzle. "It seems like you grow when you're aroused. That could be an issue."

"I don't mind," the fat lion replied, starting to rub his large paws against his soft belly, pressing deep into the warm fat and purring happily. The combination of the pleasure and the growth felt wonderful, and the growth made him hornier by the moment. Precum was already start to drip from the tip of his shaft and splashing on the ground.

"Well, I do mind. We need to keep you from growing for a few days so I can get you turned back to normal... otherwise I wouldn't be able to experiment on you again."

Ghost chuffed a bit, not really caring about that for the moment.

The scientist shook his head and walked out of the test chamber, laughing softly to himself but leaving the heavy door open. Not that it mattered, the giant lion was much too big to get out of the door now, instead he focused on pleasing himself, stroking his shaft as he felt his weight growing by the moment.

He was so enraptured with his own pleasure that he didn't even notice when Theo returned, pushing a large box along with him. With a kick of the box,he opened it up, a large bundle of leather spilling out onto the dirty floor. This finally got the lion's attention as he found himself coming up short on his rubbing, instead watching as the mad scientist carefully unwound the straps and laid them out on the floor. They were all long, but some were significantly longer than others.

"What are those?" Ghost asked, cocking his head to the side, his tail smacking at the floor.

The smaller lion smirked. "Something I made just for you," he said, then quickly clapped his hands together twice. The leather straps all snapped rigid then started to move on their own accord. They slid across the room and starting to circle around Ghost, moving closer and closer by the moment.

"Theo?" he asked, reaching out with one paw.

The leather strap shook in place, then suddenly leapt into the air, wrapping around the fat lion's paw. The other straps followed suit, leaping high into the air and pouncing on the lion. They wrapped around each limb, his paws, the base and tip of his tail. Three large straps wiggled under his belly to wrap around his girth, sinking into his fat and two more wrapped around his shaft, one at the base and the other near the middle.

Ghost let out a soft yelp and opened his mount to say something but it was interrupted when a bright red ball gag lifted out of the box and flew into his muzzle, fitting tight inside of it. The straps wrapped around his head and held it tightly into place.

With a smirk Theo clapped his hands again, and this time a number of chains shot out of the wall and latched onto the leather straps. They pulled back, his limbs drawing tight and holding him firmly in place. All he could do was wiggle slightly and moan, his belly hanging just inches off the ground. He grunted and gave the scientist a long look.

"There, that will keep you from playing with yourself. I'll let you down in a couple days once the nanogenes get you converted back to normal," and with that he turned around and walked back out of the test chamber, the door closing behind him... though not before he burst into mad laughter.

Ghost struggled to try and move but found that he couldn't do more than twitch. All he wanted to do was to masturbate, to get some more of that pleasure but he couldn't do it. He couldn't tease himself, he couldn't rub himself, all he could do was sway just inches from the ground.

His mind raced a bit, surprised that Theo even had the bondage gear in his size, let alone just laying around. Then again he was a mad scientist, this was the sort of thing they did. But really, they were exactly the right size for his weight and even for his shaft... how could he have had that ready ahead of time. Unless he knew this would happen, not just the cumming but the growth as well. He had to planed it all.

The fat lion found himself laughing into his ball gag, having been tricked by the lion yet again, and it was hardly going to the be the last time.
