Rarity routinely flipped through a fashion book that she had checked out from Twilight's library. Every week Rarity would go to Twilight's house and check out a new fashion book that she would then return the following week. This week she had checked out a particular book called, "How to Make Your Body Sexy". Rarity already knew that she was beautiful, but she liked to do everything that she could to keep it that way. Not to mention, that she just found fashion books interesting. As all of her friends knew, fashion was her passion.

It was late afternoon and Rarity had just returned from her weekly trip to Twilight's house. She was sitting at her kitchen table, drinking a small cup of tea, and skimming through her new book. She casually twirled one of her many locks of purple hair as she studied a picture of one of the models in the book.

Just as she was about to close the book and go upstairs to finish a dress that she had been working on, Rarity noticed a certain article out of the corner of her eye. At first she thought that she had misread it, but quickly realized that it was no mistake. Rarity took one last sip from her cup of tea, before levitating the empty cup over to the kitchen counter, all the while not taking her eyes off off the book. The title of the article read, "Breast Enlargement Spell". The article went on to say, "...for those who aren't happy with their breast size."

Now, although Rarity didn't particularly want to admitted it, she had never really been the happiest with her size. They definitely weren't small, but they weren't very big either. She knew that she was beautiful, everybody told her that, but she had always felt as if something very small was missing, and long ago she had decided that it was her breasts. She just wanted them to be a little bit bigger. Of course, there really wasn't anything that she could have done about it until now.

As Rarity read further down the article she noticed that at the very bottom it listed instructions on how to preform the spell. It was labeled as a adept spell, and warned that people who are inexperienced in magic should not attempt it. Now Rarity wasn't nearly as good as Twilight in magic, but she definitely wasn't inexperienced. After all, she used it all the time when she was making dresses. Of course, minor levitation spells are a lot different than spells that change your physical appearance.

"I guess I could always ask Twilight..." muttered Rarity to herself as she studied the spell, "She would be able to do it without even trying."

Yet deep down Rarity knew that she would never ask Twilight such a thing. It was unladylike and somewhat embarrassing. If she really wanted to do it then she was going to have to do it herself. After all, how hard could it be?

Rarity looked down at her boobs and cupped them, considering whether or not she actually wanted to go through with this spell. After a few moments of consideration Rarity decided that she might as well try it. If something went wrong, or if she just wanted them smaller again, she could always just change them back later. With excitement about what she was about to do, Rarity grabbed the open book and quickly sped up the stairs to her room without delay.

She closed the door behind her before stopping to look at herself in the mirror. She was wearing a long white dress that fit her figure nicely. It revealed a lot of her legs as well as a good amount of cleavage, but she didn't mind that, she liked showing off. A sparkling pair of diamond earrings complimented the dress nicely, as well as her long flowing purple hair which fell across her right eye.

After taking a few minutes to puff up her hair Rarity walked over to her bed where she sat down and opened the book on her lap. She studied the steps of the spell a few more times before taking a deep breath and closing the book.

"You can do Rarity, you can do it," she encouraged herself, placing her hands over top of her boobs.

As she focused on directing her magic energy, her hands began to glow a light blue color. The blue magic slowly seeped out of her hands and into her awaiting breasts. Rarity almost pulled her hands away when the magic first began to flow into her. It was somewhat like a slight tingling sensation that tickled. She tried not to laugh as the tickling sensation in her breasts intensified as she channeled more magical energy into them. After what seemed like hours, but was only minutes, Rarity removed her hands from her chest and eagerly looked down at her boobs to see if there was any difference.

To her surprise, her lady lumps defiantly seemed to have grown over that short period of time. Her boobs pressed at the white dress that she was wearing, which normally fit her perfectly. She could feel the slight pressure of the fabric as it restricted her breasts from expanding any farther. With excitement, Rarity quickly stood up and walked over to the mirror to get a better view of her body. As she stared at herself in the mirror she noticed that, although she was showing more cleavage now, the dress she was wearing still looked good on her. It was a little tight, but she didn't really mind that. She could always make the top a wee bit bigger in the future.

"Hmmm, I wonder what size I am now?" wondered Rarity as she ran her hands from her chest down to her waist.

As late afternoon progressed into evening Rarity measured herself and tried on a variety of different sizes of lingerie that she had laying around in her boutique. She was happy to know that she was able to pull off such a complicated spell successfully, but she was even more happy to pronounce that she had grown an entire cup size. All the way from a small C cup to a D. When the time finally came for Rairty to go to bed that night, she had no trouble sleeping with the thought that she now had something that she had always wanted.

The Following Morning

Rarity woke up the next morning, rather joyfully, and quickly got ready for her busy day. As she put on her bra that morning, which she had just measured to fit her perfectly the last night, she noticed that it seemed to be somewhat tight. This struck her as a little odd, but she just came to the conclusion that she must have been tired when she was measuring herself and that she was a little off. So, she found a new bra that was slightly bigger and put that on before continuing on with her daily routine.

After eating breakfast Rarity noticed that, once again, her bra seemed to be rather tight. This troubled her a little, because she knew now that it wasn't her measuring that was off. Her breasts seemed to be growing. Not only that, but they seemed to be growing at an increasing speed. It had taken all night for her other bra to become tight, but it only took a few hours in the morning for her new one to become too tight as well. Hesitantly, Rarity placed her hands a few centimeters away from her chest. To her dismay, the gap was filled within only a few minutes.

"I must have done something wrong when I cast the spell," thought Rarity as she looked down at her boobs with alarm, "I made them grow, but I didn't make them stop growing!"

As she began to think about what she could have possibly messed up on, her new bra started to become unbearably tight. She hastily ran up to her bedroom where she sat down on her bed and took off the white dress that she was wearing. She normally hated to wear the same outfit two days in a row, but that dress really looked good on her, especially with her bigger boobs. After she took off the dress she looked down at her breasts with fright. She was afraid that they were going to snap the bra soon. After a little effort, Rarity managed to take the bra off as well. She sighed with relief as it relieved all of the building pressure.

"Now what am I supposed to do!?" thought Rarity as she stared down at her ever-growing melons, "The spell is obviously still working it's magic, so I'd have cast a contradiction spell in order to stop it."

Unfortunately, Rarity had no experience whatsoever in counter magic. There was almost nothing that she could do. She didn't want to attempt a counter spell and possibly make it even worse if she failed, but she also didn't want to ask for help either because it was so embarrassing.

"Maybe it will stop by itself," laughed Rarity nervously, "Maybe they'll just grow to a certain point and then stop."

So, Rarity did one of the only options that she had. She began to wait impatiently for her boobs to stop growing. Of course, as time progressed, she began to slowly loose more and more hope in that theory. Her breasts were now the size of large basketballs and they showed no sign of slowing down. In fact, they still seemed to be increasing in the rate of growth. The only positive prospective that Rarity could possibly put on the situation was that they weren't sagging. They were staying nice and perky.

By now she knew that she was going to have to do something. Like it or not, she was going to have to try and preform a counter spell. Gingerly, Rarity placed both of her hands over top of her now huge naked breasts. Both of her nipples poked out between her fingers. After a few moments of thinking, she started to concentrate on preforming the counter spell. Once again, her hands started to glow a light blue color. The only difference this time, however, was that the tingling sensation in her boobs was a lot more prominent. Maybe it was because the spell was making her boobs more sensitive as well, or maybe it was just because her hands were now in direct contract with her them. Either way, the tingling sensation felt rather good this time, and it seemed to be spreading itself out all across her boobs, with the majority of it being in her nipples.

Rarity tried to refrain from moaning as the counter magic continued to flow into her. She had to stay focused. She had to do this right. With determination, she doubled the dosage and discharged even more magic into her. Unfortunately, this was a bad decision. It only increased the pleasing sensation throughout her breasts.

Unable to withhold the urge to give in any longer, Rarity began to moan with enjoyment. As she continued to work her magic, her hands began to start fondling with her boobs, before slowly moving up to her nipples. She threw her head back and carelessly let her tongue hang out as she pinched and twisted her nipples. She knew that she should be focusing on the counter spell, but it just felt so good. Unable to control herself, Rarity laid back onto her bed and continued to play with her boobs, every now and then letting out a small sharp exhale every time she pinched her nipples.

Continuing to fondle with her breasts, Rarity halfheartedly looked down at them to see if the counter spell had prevailed in halting their growth. However, the spell seemed to have no affect. They were still growing, and they were now about the size of large beach balls. Although half of her was disappointed, the other half of her was almost exhilarate by the fact that they were still getting bigger.

"They seem to be getting more sensitive too," moaned Rarity with pleasure as she lifted her left nipple to her lips, "I've always wanted to try this, but they were always too small."

With that, Rarity slipped the awaiting nipple into her mouth and began to suck on it. She twirled her tongue around it in tight circles as she continued to simulate her other boob with her hand. The pleasing sensation was almost unbearable and Rarity could feel herself beginning to become moist. Not only that, but after a little while Rarity began to taste a soft, sweet, and cream-like substance flowing into her mouth. Her breasts were starting to produce milk. It must have had something to do with the spell, but at the moment Rarity didn't really care.

As she continued to drink the sweet tasting liquid that was, by now, streaming constantly into her mouth, she also began to squeeze her right breast which started to squirt the rich creamy milk as well.

"You mustn't..." thought Rarity as she milked her massive boobs. But she couldn't hold back any longer.

Rarity slid her right hand down her slender body towards her pussy, which was, by now, extremely wet. She momentarily stopped sucking her nipple and began to moan as she slipped two of her fingers inside of her. The walls of her pussy fit tightly around her fingers and she slowly slid them back and fourth. As she continued to finger herself, Rarity rearranged her tits in such a way that both of her nipples would fit into her mouth. The warm stream of creamy milk poured out into her mouth twice as fast as she began to finger herself more quickly.

"Well, if I'm going to do this then I might as well do it right!" sighed Rarity temporarily stopping her session.

Reluctantly, she pulled her fingers out of herself and reached over towards her nightstand. Opening the drawer revealed a large purple dildo awaiting inside. It was her favorite toy, so she kept it in her nightstand drawer for quick access. Pulling the dildo out of the nightstand, Rarity spread her legs wide open and lined it up with her pussy. Without hesitation, she thrust the large toy into her tight pussy. As she began to gain speed she started crying with pleasure. He tongue hung out of her mouth as she bounced up and down from the thrusting force and groped her boobs. By now her boobs where enormous, about the size of a yoga ball. She didn't think that she would be able to get up from the bed if she wanted to. Her breasts were pinning her down. They bounced in sync with Rarity's thrusting as she continued to dig the dildo deeper into herself.

Suddenly, Rarity flipped a switch on the back of the toy and it began to vibrate. This was too much for her, and she began to pump her hand back and fourth as if in turbo mode. Meanwhile, her tits were continuing to spew out milk as she played with them.

"I think... I think I'm.... going to cum!" panted Rarity feeling herself reaching her climax.

Her back began to arch as she thrust the large vibrating dildo into herself forcibly.

"Ahhhhhhhh!" cried Rairty with great pleasure stopping in mid-thrust and throwing her head back, "I'm cumming!"

After she had finished Rarity switched off the vibrating dildo and laid limply on her bed. Her large boobs were still slightly trickling out some milk that was dripping down her now sweaty body, and the toy was still thrust half way up her pussy. She took a second to close her eyes and just soak in the pleasure of one of her most delightful orgasms ever. However, while her eyes were closed she noticed that the weight on her chest was beginning to disappear.

Rarity opened her eyes, and, to her surprise, she noticed that her breasts were actually starting to become smaller. They were reducing in size even faster than they had been growing. After a few minutes Rarity's boobs returned back to what she assumed was her original size. She must have done something to reverse the spell while she was masturbating. Although Rarity was, for the most part, happy that her breasts had returned to normal, she was still going to miss them a little bit. The sensation that they had given her was positively fabulous.
