Slowly, Rarity began to emerge from her slumber. She had no idea where exactly she was. It seemed to be the same place where they did those experiments with magic and such. They told her they wanted to know how magic worked, and that they had "created" her. Rather, they had made a modified copy, but her memories were still the same nonetheless.

The only difference was that, instead of her normal pony body, they had given her memories a genetically-modified anthropomorphic body, which took her some time to adjust to. She had noticed that her magical abilities, the thing they were trying to research, did not work when in this body. She didn't know why, and neither did those humans.

As she became more and more awake, she realized something else. she was strapped to a chair. Naked. Previously, she wouldn't have cared that she was naked. Ponies were naked most of the time, though clothing was becoming something more and more regular, not just for fashion. This was probably due to the fact that the enviroment was becoming colder, but she wasn't sure. What she WAS sure of, was that humans (and thus anthropomorphic ponies as well) had to wear clothes. It was considered incredibly indecent to not wear any when being around others.

This was something she learned and adapted to rather quickly, being embarresed whenever she had to strip down to nothing more than her silky white underwear to place diodes for tests. The clothing was given to her by the humans, and although they weren't exactly fashionable, the material that they were made with felt incredible. Both her bra and panties were a bit too small, but she didn't tell anyone, as she liked how her panties dug into her pussy, grinding between her folds with every movement of her decently wide hips.

She had seen what the female humans looked like. They had told her that "bigger is better", and she was certainly bigger, in more than one way. Not only was she above average in terms of height, but her breasts, soft E-cups, were certainly above average aswell, being just slightly bigger than her perfectly round asscheeks, which where atleast as soft as her tits, if not softer.

Now that she wasn't wearing any clothes, she felt very naked, which, to be fair, made sense, as she was indeed naked for all to see. Luckily for Rarity, there was nobody there to see her. Or so she thought. As she was looking down at her body, she heard a speaker-system turn on.

"So Miss Rarity, it seems you are awake!"

She jumped, or jumped as much as one could do whilst strapped down into a chair, arms tied behind her back with rope.

The voice continued. "I bet you have atleast two questions: Why are you tied up, and why you are naked. I have an explanation for both."

Rarity kept swinging her head around, making her large breasts swing violently from side to side as she tried to see if there was anyone else in the room that might be watching her.

"I see you are looking for something. Or maybe someBODY? Well, don't bother. Cameras are something you'll understand at some point, but today won't be that day, unfortunatly. Just know that, we can see you, but you can't see us."

Us? That means... that there are atleast two or more people watching her, this instant, while she is NAKED? She felt embarresed, but at the same time, she was slightly turned on by that thought, as much as she hated it. She began to feel a dampness between her legs, as a clear fluid slowly began to drip down her perfectly tuned legs.

"Getting excited already?" asked the voice. "If you like this, you are going to love what we have planned for you today!" The voice sounded genuinly happy.

Rarity wasn't sure how to respond, so she said the only thing that came to mind at that time: "Let me go, you ruffians!"

"Oh, you are not going anywhere. Nobody is going to know what whe will be doing here, ever. But don't worry, we'll wipe you memory as soon as we're done, so you will never remember that this even happened!"

"Wh-what?! Don't you dare! You do not handle a lady like that!"

"Now now, no need to get angry. Just relax. It'll be fun! Trust me, you are going to enjoy this jsut as much as we are." After the voice finished his sentence, a small hatch opened from the roof of the white padded chamber. out of the dark hole came another rope, this one having a hook tied to the end of it. Rarity had no way of seeing it come down towards her, but she suddenly felt the cold metal hook on her back, grabbing the rope that was used to tie her hands together.

After it had latched onto the rope, the hook slowly lifted back up towards the roof, lifting Rarity's arms up behind her back, all the way until they were stretching her arms up completely, and then proceeding to go up, slowly lifting Rarity up as the restraints that kept her to her chair were released. She continued to squirm as she was hoisted up, now hanging from her arms as her breasts and pussy were now clearly shown for all to see, while her chair had now dissapeared back into the floor beneath her.

"What are you going to do to me?! Why are you hanging me here?"

"You'll need all the space you can get, trust me. Don't worry. You'll understand soon enough." As the voice said this, another hole opened up, this time behind Rarity, and out came a robotic arm holding a needle, which was filled with a green substance. A lable on the siringe read: BREX-82XL. "Now, you might feel a little prick in just a second..." Then, the needle made its way into Rarity's plump posterior, making her give out a small shriek as the cold and tiny metal rod inserted itself into her left bottock. When it had planted itself firmly into her rear just behind her Cutie-Mark, the contents of the siringe were forced into her body, after which the arm quickly returned back inside the wall.

"What was that for?! You could atleast warn me next time!" she exclaimed into the camera, as she had nobody to yell at directly.

"I did. Anyway, you should feel the effect of the serum in a few seconds, if our simulations were correct."

"Serum? Are you saying that that cold, disgusting thing shot something into me?!"

"Yes, exactly!"

Rarity didn't know what to say, so instead of saying anything, she focused on the warm feeling that was growing in her bossom. Letting out a quiet moan, more fluids continued to poor down her legs, dripping down onto the floor, and eminating a strong sexual odour. She could feel something brewing in her breasts, as her nipples began to stiffen from arousel.

"Ah, it seems the serum is beginnning to kick in. Now, time to enjoy the show!" said the unnamed voice.

As she looked down at her breasts, she began to feel a stretching feeling on her skin. Then, without warning, her breasts grew atleast half a cup-size, jiggling slightly, and leaving Rarity hanging there with her eyes trained on her expanding tits. But it didn't stop there. Slowly, her breasts continued to expand, audibly creaking as her skin stretched out more and more, her tits now atleast F-cups, while still expanding.

Rarity kept moaning, louder and louder, until she was practically screaming out of pleasure. She had never felt anything like that. Her breasts, now swollen beyond any known cup-size, and reaching the volume of two small beanbags, were stretching out her skin massively, making her tits unbearably sensitive. They reached all the way down to her hips already, and they showed no sign of slowing down. Her nipples, stiffened from arousal, were pointing straight ahead.

"It looks like the serum is working. Great! Now, let's see how long this is going to continue."

And continue it did. As Rarity's bossom continued to grow past her hips, it began to sag inbetween her legs, and the bottom of her breasts were now covered in her own juices. She couldn't believe what was happening. All she knew, was that she wanted to be BIGGER. MUCH bigger. Bigger than anyone or anything. Her tits were now reaching her knees, extending some 5 feet in front of her chest. They were feeling heavy, and she could feel something sloshing around in them.

As her breasts reached her feet, the pressure in her tits grew too large, and she could feel a warm liquid travel down from her nipples, creating a steady stream of milky goodness down her massivelly engorged bossom. The bottom of her massive tits came closer and closer to the white floor of the enclosed space. Rarity could do nothing but watch, as her senses were scrambled and hazed by the growing sexual arousal from her oversized and stretched-out bust.

The flow of juices from her slit became heavier and heavier, eventually becoming a steady flow sliding down her legs and breasts. A small puddle was forming on the ground, a feet or two above her hoof-feet hybrids. After another 30-or-so seconds, her massive tits had finally reached all the way down to the ground, landing in the puddle of her own love-juices, covering the bottom of her now rubbery breasts with them.

"We have touchdown!" announced the voice over the speakers into the room, but Rarity didn't even hear it anymore. All she could think about, were the two funbags attached to her chest, which had both reached the size of a small car, and were still not showing any sign of slowing down. She was in nirvana. She couldn't think anymore. Any hope or will to get out of this situation completely replaced by the growing need for release. She was practically trembling with arousal, making the entirety of her tit-flesh jiggle with each motion.

She moaned and screamed, shook and shuddered, all the while being watched trough the camera. On the other side of the connection, it was decided that she had served her purpose well, and that the experiment had been a succes. Serum BREX-82XL had been proven to be functional and -somewhat- safe, and that's all that mattered. Now, they had just one thing left to do:

Return Rarity to her normal state.

The hatch behind Rarity opened once again, this time holding a different syringe, this one containing the anti-serum for the BREX-82XL serum. It made its way once again to her posterior, and rammed itself into her beautifull ass, filling her left buttcheek with the cold anti-serum. Rarity didn't even feel it anymore, nor did she protest. She just wanted to orgasm, as she knew that she was on the edge of either cumming or passing out.

The anti-serum worked in quite an interesting way. Rarity liked what it did, as the serum had reached her slit, and was now also making its way to her stiff nipples, which were still pumping out a small bit of milk. After another two seconds, Rarity felt like her entire body was on fire. Then, it happened.

She climaxed, releasing a heavy squirt of hot love-juice from her pussy and staining her tits and legs, whilst a small burst of milk erupted from her hardened nipples, covering the wall in front of her, making it even whiter than it already was. She felt amazing, as she was in complete bliss for several moments, before passing out from the unbearable amount of stimulants she was receiving from her nether regions.

Her tits began to reduce in size, going back to H-cups, then G, then F, where they stopped. They were stretched out after all, so returning them to her exact previous size would require more intricate procedures, like making the breast-skin tighter. "Alright, seems she passed out. Wipe her memory, clean her up, put some clothes on her, and prepare the next test!"
