When Rarity seeks out different ways to be 'pleased', Twilight gets her a vial that will "change" her temporarily. Rarity like the change more than she thought she would.

Rarity never was a... fetish sort of person. Plain old vanilla pleasures worked just fine for her, until as expected, she got bored of them. A lady can explore that domain without being scrutinized, right?

A passing mention of this to Fluttershy soon reached Twilight, who simply seemed to disappear for a few days then returned, only leaving a small bottle at her Boutique with a note attached to it, saying to try it when she's alone...

It's closing time, no one's home, and she has an entire night to herself...

She doesn't know.

Rarity considered. She had no idea but what the little vial would do to her. But Twilight told her it would be great, that it would be fantastic. She just randomly entered her Boutique, and dropped it off with a note signed by her. 'She can be as odd as Pinkie sometimes,' she thought. She stopped by earlier that afternoon to remind her of the vial, and to drink it "when the time 'feels' right", in a tone that stuck Rarity as rather odd, coming from Twilight. It was late at night, Sweetie Belle was sleeping at her parent's house. Opal was there too.

It was for that specific reason she thought of tonight to do it.

She wasn't even sure what the vial was supposed to do. She knew she had to drink it apparently, and then...?

Getting up from her bed, she walked up to her drawer next to her mirror, and carefully picked up the note Twilight left by it. Alternating between herself and the vial, she read the note carefully :

"Dear Rarity:

I decided to leave this you today. It's a drink that Zecora and I have worked on. You see, I have been looking at different... ways to... experience endorphins-"

Rarity widened her eyes at reading that, then shook her head in amusement. 'Really Twilight?' she thought.

"- and I think I've discovered a new way to experience them! I took it home, and drank it myself, and I have to tell you, it was one of the interesting experiences I've ever had! It was like reading a shiny new edition of the Equestrian Encyclopedia of Everything!-"

Rarity chuckled. 'That girl sometimes...'

"-Except even better!"

She held out the paper further from her face, as if she didn't believe what she had read. Did Twilight really write that? Did she really write that the experience from drinking that... she glanced at the bottle. ... thing? was greater than reading what is probably her favorite book on knowledge? The bright golden liquid glistened slowly in the low ambient light of her Boutique, and she could note a small mist moving about inside, as if wanting to escape the vial and enter her room.

She had to tear her head away from the glass to continue reading the note.

"Now I know you might think I'm lying to you, but it's honestly true! I can Pinkie Pie Promise even!"

She glanced again at the bottle, eying it almost suspiciously this time. She continued reading the note.

"This is why I want you to try it Rarity, I want you to experience it for yourself. Think of it as a gift! I prepared a batch for you. Just drink it and let it do its magic."

While reading, Rarity subconsciously went over to her bed.

"Speaking of magic... there are a few things I must warn you about."

She sat back down, on the right edge of her bed, facing the outside window. Moonlight peered in through the open curtains, signaling Rarity out like a spectacle.

"One: do not take more than three gulps of the liquid.
Two: cast a sound-proofing spell on your house. You do not want anyone outside (or inside... see three), hearing you.
Three: Be sure you're alone when you try this. Now I know you will definitely want to try it with more people later after you finish... but that's afterwards. For now, just you.
Four: It might... or rather, will... change you quite a bit, but don't worry. You'll be just fine by the end of it. Don't panic. Trust me, DO NOT PANIC.
Five: Enjoy!

-Twilight"

Rarity lowered the note from her eyes, gripping the perimeter of the paper harder than she should have as her mind raced in thought. Would she go with it? Should be drink it? Surely her best friend wouldn't do anything to hurt or harm her, she trusted Twilight with her life.

'Still,' she thought. 'Those warnings... they sound way too ominous to me.' She looked back at the end of the fourth warning. "DO NOT PANIC." Rarity said aloud, almost uneasily. That's what she should've done earlier that morning...

A customer had the gall to not only insult her appearance, but her Boutique and designs. Just who did he think he was? She angrily threw him out of the Boutique for his rudeness. Especially after he insulted poor Fluttershy, who was visiting. 'The nerve of some people,' she thought. 'All because of a simple suggestion...'

Setting the note back down on the edge of her bed, she once again walked over the drawer where she had placed the little bottle. She sighed slightly as she looked at herself. She wore a simply light dress, blue and white, with the string tied tightly behind. It gave her a more 'sexy' sort of look, but didn't reveal too much. 'Unladylike to reveal too much of yourself.' she thought. She regarded her... mammaries. She hated using any of the rude terms men liked to use. It was so degrading to women and certainly to her. But despite that, Rarity couldn't help but feel impressed by them. '34C is quite a suitable size,' she thought. She pulled her dress closer to her skin, revealing delicate curves and waist. 'And they do compliment my curves quite nicely,' she figured. She backed down on her the side of the bed next to the mirror and placed her left leg on the table that held the mirror, followed by the other. She had long, well-toned, almost glamorous legs, with her slightly thick thighs meeting up with her forelegs graciously as she wiggled her toes, placing her feet on the edge of the table.

"I do look gracious." she finished. "No idiotic guffaw can say I am not."

She turned around to look back at the note at the other side of her bed. 'What does it mean by 'change me''? She considered. 'Will it change my appearance... or change... what?'

She removed her feet from the table and placed them back on the small rug next to her bed, then stood up. No point to keep on waiting. Using her magic, she cast that sound-proofing spell that Twilight said in the note on her home, making sure that no one outside could hear. It was now or never.

She reached out, and grabbed the bottle. Carefully removing the cork, she held it at eye-length. She could smell its aroma, it smelled faintly like daffodils. 'A pleasant smell at least' Rarity observed. She peered down the neck of the open bottle to the golden fluid. Sighing, she slowly brought it to her mouth, and carefully, took two sips of the liquid. It swirled around in her mouth for a while as she gulped it down, feeling in slush down her throat.

Rarity wiped her lips. It didn't taste bad at all, a little viscous, but nothing bad. Now she waited, briefly wondering how long she would have to wait.

Not long at all, as she quickly found out.

Rarity tilted her head. She carefully placed the bottle back on the table in front of the mirror.

Then, she felt it.

A small tingling feeling, coming from her right hand. It quickly spread out like cold water through her right arm, swirling through, reaching her shoulder. Rarity shivered as she felt that icy feeling seem to concentrate in her chest and lower back, almost like a knot, becoming slightly uncomfortable, feeling that 'knot' seem tighter and tighter. She began to sweat, her breathing quickening as her nervousness began to show. A feeling of dread came over her as her hands began to twitch, the knot almost seeming to suffocate her from the inside-out...

Then, just as suddenly, the 'knot' loosens.

Rarity lowered her head and moved her arms closer to her body as she felt was seemed to her almost like electricity jolt from the knot's former place and shoot through her entire body, feeling a curious sensation as the jolt spread to her thighs, moving towards her legs, then returning to her center, traveling through every inch of her body, finally resting at her feet and disappearing, all in a small wisp.

Recovering, Rarity tried to stand up as she felt the sensation leave. 'Really?' she thought. 'THIS is what Twilight wanted me to experience? THIS is what's so amazing?' she thought, almost angrily. 'I'll be having several words with that girl...'

She got up from the bed, and as soon as she took one step, she felt something again, coming from her thighs, Rarity winced and braced herself, shutting her eyes from the dread of what was to come.

This new sensation, though, was different. It wasn't exactly pleasant, but it was better than before. Almost like being tickled. Rarity shivered once more as the sensation started started to spread, moving towards her toned forelegs as she tried to stand back up again, only to find that she had trouble doing so. She looked in the mirror. What she saw shocked her.

While Rarity wasn't thick, she did have some extra mass on her. Her thighs flexed and the curvature of her muscles could be seen through the soft layer of fat, complimenting her figure.

But now...

Her left thigh was slightly larger than the right one. A small budge seemed to appear as she looked at herself, her thigh slowly growing bigger as that tickling sensation returned.

"Twilight...!" Rarity exclaimed to no one, anxiety growing in her voice. "What... what have you done to m..."

She never finished her sentence, yet another new sensation suddenly poured into her. But this one was different. It felt... good.

Rarity closed her eyes as she started to wiggle her toes, the unknown, but nice, feeling growing stronger within her. Rarity opened her eyes and looked in the mirror once more. So was she.

Rarity arched her back towards the bed as she started to note the ceiling becoming closer to her, inch-by-inch, each little spurt of height sending her mind reeling, feeling the desire for more increasing with every inch. The dress she was wearing felt tighter and tighter, so tight that she felt and heard the cracking sound of a fabric threatening to rip. Sighing at the sensation, she scrambled to remove the dress, quickly moving her hands to the attachments in the back to remove the dress. However, as soon as she touched it, the dress came loose, coming off quickly and dropping to the floor. Rarity sighed and moved her now-longer arms upwards, enjoying the new-found freedom. Her bra and panties were the only thing left, they too becoming tighter and tighter as Rarity inched higher in small occasional spurts, each time sensation now sending wonderful feelings through all her body. Her breathing quickened, and she began to pant, as her breasts began to expand, stretching her bra until she once again heard the small cracking sound of fabric beginning to rip. Not bothering to remove them, she left her bosoms buckle against the cup, the outline of her nipples imprinting on the felt of the bra as the bra came free with an audible snap. Rarity sighed in delight as she felt her now enormous breasts coming free, bouncing slightly, audibly against her chest. The wonderful sensation now turning into pleasure, Rarity moaned as she felt her hips begin to widen, the buttons of her panties straining against their restraints. Her vaginal outline pressed tightly against it, with a visible dark smudge, stained by Rarity's growing excitement.

"Oh dear Celestia..."

The three buttons that held her panties together slowly came loose, with the first unbuttoning itself, followed by the second,

"Oooh..."

Then the third,

"Ahh...!"

as the cloth snapped, having reached its limit, and fell to the floor next to her, Rarity sighing in bliss as that tension left her, her crotch finally free from their felt restraints.

Rarity's growth had stopped, and she felt a small tingle throughout her body. She slowly stood up, pushing herself against the bed to support herself, and looked at the mirror, taking in her new form. She was now at least 12 feet tall, the tip of her head just a few centimeters from the ceiling should she stand on her tippie-toes. Her breasts, now as least a twice the size of a normal human's head, stood proudly against her chest. Rarity took a hand and slowly rubbed against them, taking in their form, their texture. This felt good, this felt right. Rarity purred at the pleasant sensation, beginning to feel herself moisten again. Still looking at the mirror, she lowered her other hand and began to slowly rub it around her waist, trailing around her even-more-pronounced curves, her hands lapping up small droplets of sweat that had built up from Rarity's experience.

She had back down on the bed again, as she began to imagine how... incredible her new form was. She was the pinnacle of a woman, an object to be admired and inspire awe. She was a living work of art, her glamorous body displaying the true ideal of a female.

Rarity closed her eyes, her mind racing with thoughts. What would her friends think of her new form?

She blushes slightly as she sees her friends. All of them, gasping with surprise, but quickly approaching her and admiring it. She imagines Rainbow Dash envious of her monstrous mammaries. She imagines Pinkie Pie jumping up and down, excitedly blabbing about whatever party she wants to throw for her now. She imagines Applejack, blushing, delightfully, looking away at her newfound glamour. She imagines timid little Fluttershy, blushing harder than Applejack, covering her eyes with her hands, hiding behind her hair as she is overwhelmed by the presence of perfection. She imagines Twilight...

Twilight...

Rarity shivered as she thought of her. It was Twilight who gave her this. The reason why she's a work of art now.

Her lower lips began moistening further, the edge of the bed becoming wet from her enlarged mound. Rarity rubbed her thighs together in need as her thoughts turned dirty.

She now imagines Rainbow gripping her enormous mountains placing her head between them, licking the space in between. She imagines Applejack oogling her left breast and taking as much as she can into her mouth, failing to even get her nipple. She could almost feel her hot, sloppy tongue trail around her nipple, searching for any sensitive spot, only to find none...

Rarity lowered her hand towards her nethers and slipped a finger in, entering her now nearly-gushing insides easily. Perhaps she should slip in another one... and another...

Rarity grunted as she slipped four of her fingers into herself, continuing to imagine her friends service her. She imagines beautiful Fluttershy, peaking out from her bangs and lightly touching the breast that Applejack wasn't attending to. Rarity moaned as she then saw Fluttershy's mouth water and fiercely kiss her nipple, then moving downwards, planting soft, wet kisses as she made her way downwards.

Then Twilight...

She gave another loud moan as she moves her breast towards her mouth, sucking on it as she imagines Twilight standing up, admiring her form, then moving towards Rarity's grandiose slit, having to step on a small chair to be on eye levels. She then ima- ooh!

Rarity gives a deep groan into her breast as she sees Fluttershy reach down there at the same time Twilight pushes her head in and starts licking her down there, lapping up and swallowing her juices, not letting a drop be wasted. She then imagines Twilight deeply kissing Fluttershy, who kisses back as she feels her soft, delicate hands caress her large clit, as she feels her friends start to shift positions all around her, Pinkie nibbling her rear, Applejack licking her legs, Rainbow groping her back and neck, sending wave after wave of complete ecstasy throughout all of her body...

It was too much.

"Oooooh sweet, sweet Luna!"

Rarity cried out in utter felicity as she felt her walls tighten around her hand, her eyes shut and her hips thrusting against her hand as her nectar gushed out, splattering against the nearby wall, staining the sheets. Her back arcs again and again, her entire body almost convulsing as she was overwhelmed by the intense sensation, her breathing ragged and rapid. At last, finally the last of the most intense orgasm she had ever experienced subsided, letting out a blissful sigh of satisfaction as she laid on the bed, resting in the aftermath. She open her eyes and pulled herself up, sitting on the bed. She looked in the mirror.

She was normal size again. No more of her artwork. No more of her new body.

Upon realizing that, she almost pouted. Her breathing returned to normal, her mind finally settling on one thing:

That was the most amazing experience she had in her life. 'Why did that feel so good?' She wondered. And it had to end so quickly as it came.

Rarity sighed sadly as she realized that.

However, she remembered the bottle. Eyes widened, she sat up and walked away from the bed towards the post, where the bottle lay.

There it still was, lying there, glistening in the night light. It seemed like barely any of its contents were used at all. Rarity smiled gleefully.

She looked towards the window. The moon was no longer visible, it too far above in the sky to be seen at that angle. Small twinkling stars appeared above one larger one, the smaller stars alternating, forming a near-circle.

Rarity sighed once more as she gripped the bottle in her hand, looking at the note Twilight sent. 'Yes Twilight,' she thought, 'I will definitely want to try this with more people...' She lets out a quick needy groan as she remembered her imaginings of her friend's thoughts to her growth. Her breathing became erratic, her eyes taking on a more lustful tone. She spoke her next thoughts aloud, making sure only she could hear even though no one else was there:

"Starting with you."
