Sweetie's A Big Girl Now

 

Be Anon.

 

You had shown up at Carousel Boutique to spend the night with your lady friend when you were met with a surprise.

 

Lately, a new spell had taken Equestria by storm. It was a mass transfer spell that allowed matter to be temporarily swapped between two similar bodies.

 

Or, in this case, female bodies—one of them belonging to your girlfriend, Rarity.

 

"So your breasts haven't permanently shrunk?" you ask cautiously.

 

"No! Well, not permanently. Sweetie Belle wanted to borrow some mass for a slumber party." Rarity explained, "It's only until the break of dawn, I'll be back to normal at sunrise. You don't mind, do you?"

 

You were a stranger in this land so things like magically lending your younger sister your boobs as a gag for a sleepover was beyond your understanding. But Rarity still had some admirable sweater puppies left over, even if they were now basketballs instead of the beachballs you were accustomed to.

 

"I think I'll live."

 

"Oh good," your girlfriend smiled, "Because that means that I can hold you even closer to my heart tonight. Among other things..."

 

---

 

Sure enough, in the morning she was back to her typically enormous proportions. You were just sad that you slept through her return to super-hugeness.

 

You were downstairs fixing breakfast when Rarity's little sister, Sweetie Belle, burst in.

 

"Rarity? You can take your boobs back already. Shouldn't I be back to normal by now?"

 

You stared in shock.

 

Sweetie Belle had beachball sized boobs that were barely contained by her huge stretched out t-shirt. They were almost as wide as the kitchen door which forced the tween to slow down as she entered the kitchen. With the way they were wobbling and the fact that you can see the outlines of her plump nipples you knew she wasn't wearing support of any kind.

 

She saw you and paused, "Oh, hello Anon. You slept over again?"

 

You nod and stammered that Rarity would be down soon. After that you both stood around awkwardly, you making breakfast and Sweetie trying to figure out how to stand with her brand new boobies.

 

It wasn't that Sweetie's breasts were the biggest you'd ever seen. Rarity's were still bigger, for instance. It was the fact that such a short, skinny kid had such a tremendous set of knockers. You were surprised she could still stand up strait. Of course, Rarity's mega-mams had never seemed to weigh her down so maybe there was some magic involved.

 

"I can't wait for Rarity to undo this spell so I can get rid of these things." Sweetie patted her chest. "That mass transfer spell was super fun, but I'm glad I don't have to deal with these things all the time."

 

Mass transfer spells had become very popular lately. It was a pretty simple spell too, so just about any magic user could use it to transfer size between two things. Or people. You couldn't use magic so you weren't really sure, but you thought most transformation magic was supposed to wear off after a while.

 

Which reminded you...

 

"Sweetie, the thing is, about Rarity..."

 

Rarity bounced into the kitchen, her breasts looking as full and round as always. The sisters looked at each other. Rarity looked confused and Sweetie Belle looks shocked.

 

"Sis, your breasts are back to normal? But mine..."

 

"Sweetie, why are you still so big?!"

 

You didn't know what to do in such a surreal situation, so you said the first thing that occurred to you.

 

"Um, pancakes anyone?"

 

---

 

You all did end up sitting down to eat pancakes; after Sweetie Belle stopped crying and calling herself a freak, much to Rarity's annoyance.

 

It was a fairly normal breakfast. Except for the fact that Sweetie had to learn to eat while sitting sideways at the table like her big sister.

 

And the fact that Sweetie ate like a starved horse.

 

You and Rarity watched as the kid packed away pancake after pancake. Eventually you made a whole second batch. Which Sweetie ate all by herself.

 

Maybe having ginormous jugs gave her a ginormous appetite?

 

After breakfast you were cleaning up when you heard a cry from the parlor. You rushed in and saw Rarity with a worried look on her face. Sweetie Belle was doubled over, clutching her stomach and moaning in pain.

 

"Oooh Rarity, it hurts so bad!"

 

"What hurts?" your girlfriend asked.

 

"Everything! Ooh..."

 

You helped the poor girl over to Rarity's fainting couch where she curled up as much as she could around her chest pillows.

 

"Should we call an ambulance?" Rarity asked you.

 

By the time you answered, Sweetie had calmed down. You told Rarity it was probably just a cramp from eating too much and that you should probably wait for a few more minutes.

 

It didn't take long for Sweetie to recover from whatever happened. She moved to stand and you helped her to her feet. The first thing you noticed was that she felt heavier then before. As you held her by the waist she also felt quite a bit softer?

 

When she stood up strait Rarity gasped. Sweetie was taller then she had been a few minutes ago. Her skirt was shorter and her t-shirt sleeve pulled up further on her arms.

 

That wasn't all.

 

Your girlfriend's skinny little sister wasn't looking so skinny anymore (monster sweater puppies notwithstanding). Her skirt was pulled tight across wider hips and a much rounder butt.

 

Had Sweetie just had a growth spurt?

 

You turned to Rarity.

 

"Okay. Now we go to the hospital."

 

--

 

You all didn't go to the hospital immediately.

 

Rarity had to get Sweetie Belle something to wear. After the spell yesterday she had loaned Sweetie some shirts and a bra to wear to the sleepover but now it didn't fit right after breakfast. Her boobs weren't much bigger, fortunately, but the rest of her was.

 

The last time you saw Sweetie, a few days ago, she had been thin and gangly like a typical middle school girl. Now she looked more like a freshman in high school despite her girlish face.

 

Even though Rarity was freaking out you could tell that she enjoyed putting together an ensemble for her larger little sister. When everyone was ready to go you looked at them standing together. Sweetie Belle was only half a head shorter than Rarity now and her boobs were definitely smaller, even though they were still watermelon-sized.

 

You had gotten used to the fact that about a third of the women in this world were what Rarity called "bosom plus" sized, and you definitely appreciated your girlfriend's plus sized bosom, but it was weird seeing Sweetie like that. She was just a little girl after all, even though she looked less like one with every passing hour.

 

By the time you got in to see the doctor Sweetie had grown some more. Mostly her face looked more mature and she was a bit taller. She now looked like a high school underclassmen with two medicine balls stuffed under her shirt.

 

How these bosom plus women maintained there shape was beyond you. Probably magic of some kind.

 

The rest of the morning was a whirlwind of nurses, doctors, and tests. By the afternoon you were just waiting on test results.

 

Oh, and after lunch Sweetie Belle had another huge growth spurt.

 

When you all arrived, they had made her change into a hospital gown designed for busty women and confined her to a wheelchair. After lunch at the cafeteria you were pushing Sweetie back to the waiting room when she cried out and hunched over. You quickly rolled her into an empty room so she could ride out her changes in peace and it was a good thing you did.

 

Sweetie moaned as her thin green gown billowed out around her breasts. The sleeves worked their way up her arms and big gaps formed along her back where the gown was tied.

 

You couldn't believe what was happening. Even her cries of pain were changing, going from girlish squeaks to longer and deeper groans. You couldn't see her face because her hair was draped over her bent head and it had gotten much, much longer since this morning, falling to her mid-back.

 

This time it took a little longer for her to recover than she had in the morning but eventually Sweetie sat up. Both you and Rarity were surprised once again.

 

The first thing you saw was Sweetie Belle's face. All traces of childishness were gone. The girl now looked like a high school senior, with high cheekbones and plump lips.

 

It was obvious her frame was longer too, going by the length of her arms and neck. You really couldn't see any of the rest of her body beneath her voluminous gown except her boobs. You could definitely see those.

 

Her breasts had filled her lap before, but now they had gotten so full that they spilled over the sides of her wheelchair. And they still had that magically round shape which was clear because you could see her thick, fat nips poking strait out through her thin gown.

 

Of course, you probably shouldn't have been staring at them, but fortunately neither sister seemed to notice.

 

Sweetie wanted to see what she looked like in the room's mirror and asked for your help. Grabbing one of her arms, you steadied her as she stood. You tried really hard not to pay attention to the way her closest boob smooshed up against your entire lower body. Or how her large, round, perky bubble butt was on full display through the gaps in the back of her gown.

 

Fortunately for your sanity Rarity noticed and adjusted the gown with its bigger ties. Unfortunately, even re-tied at its largest size there still wasn't enough cloth to cover both Sweetie's breasts and close fully around her back, but at least her bottom wasn't exposed anymore.

 

The growing girl was still a little wobbly on her feet so you and Rarity stood on either side to help steady her. Well, you stood by Sweetie Belle's side as one of her boobs eclipsed half your torso. Rarity, on the other hand, had to stand a few steps away because her own jumbo jugs were colliding with her sister's newly swollen ones. That's when you realized Sweetie's bosom was now larger than Rarity's.

 

But that wasn't the only way in which the younger sister had surpassed the elder. She was now a little taller than Rarity too, though it was a little harder to tell at first because of both sibling's poofy hair. But yes, Sweetie's eyes and mouth were a few inches above Rarity's. And even though you were six foot three, Sweetie now came up to your nose.

 

"Gosh. What's happened to me?" Sweetie said as she looked at herself.

 

Her voice matched her looks. It was mellow and mature sounding. Hearing that voice was what really sealed it in your mind that Rarity's little sister wasn't a kid anymore.

 

Rarity seemed to realize it too because you could see her getting teary-eyed. She was probably overwhelmed that her baby sister was all grown up.

 

You all spent a few more minutes in front of the mirror, Sweetie examining her new body, Rarity trying not to loose it, and you trying not to dwell on how hot your girlfriend's kid sister suddenly looked.

 

When you get back to the waiting room the doctor was there with the test results. From what they could tell, the mass swap between Sweetie's and Rarity's breasts had somehow tricked the younger girl's body into thinking it should be bigger and more mature than it was. As a result her hormones were in overdrive and that, combined with her own magic, was causing her to grow. The big problem was that the doctors weren't sure just how big Sweetie was going to get because her body seemed pretty confused.

 

That's when the doc suggested giving her a dose of female hormones. As weird as it sounded, the hormones that made a girl look more like a woman also usually caused her to stop growing taller. So they hoped that by giving Sweetie Belle female hormones that would stop her getting taller.

 

Personally you were a bit worried about giving Sweetie anything that might make her boobs even bigger, but both her and Rarity seemed to think that getting too tall was worse so they agreed to the shots. It was going to take some time to get the hormones together and they wanted to keep Sweetie Belle overnight. The poor girl was so frazzled that both you and Rarity agreed to stay until after they administered the shots for moral support.

 

Around dinnertime you reminded Rarity that no one had contacted her and Sweetie's parents to tell them what had happened yet. Mortified, your girlfriend went off to find a phone while you and Sweetie Belle finished dinner. In fact, the young woman finished her dinner, Rarity's (who wasn't hungry), and most of yours.

 

You were starting to see a pattern but the doctors hadn't said anything about limiting her food intake so you decided not to make an issue of it. Especially after Sweetie complained so cutely about how hungry she was.

 

Both of you talked for a bit, you in your chair and her sitting up in her hospital bed. After a while Sweetie got very quiet and you asked her if she was okay.

 

"I guess." she mumbled, "I just feel so strange. I'm getting so big and I must look really weird. All my friends are gonna think I look weird."

 

You assured her that even though she was bigger she didn't look weird. In fact she looked rather pretty, like her sister.

 

"Really?" Sweetie got a small smile on her face. Then she frowned a little, placed her hands on the either side of her boobs, and pushed them up a bit.

 

Staring down at her stretched out gown she asked, "And you don't think these are too big?"

 

You were amazed she could even lift her medicine ball sized breasts the few inches that she did. Although you could see Sweetie's arms and they were looking fairly toned as they pushed against their load.

 

You blushed when you saw how hefting her boobs caused the front of Sweetie Belle's clothes to stretch tight across her new bust. Her big thick nipples drew a tight line across the thin hospital clothing. As the girl presented her chest for your consideration you looked away and pretended to be deep in thought, both to hide your embarrassment and to give yourself time to think.

 

You didn't know how to respond to her question without getting yourself in trouble. Carefully, you reminded Sweetie that her sister had a large chest too and Rarity was very pretty, so she should have no problems.

 

Sweetie Belle beamed at your indirect compliment. You felt like a tightrope walker, trying to bolster the young lady's confidence without saying anything inappropriate.

 

Sweetie start to say something about her classmates and how they'd react to all this when she paused and got a funny look on her face. You asked what the matter was and she looked at you with a worried face.

 

"I think, I'm growing again."

 

Oh crap, you thought as she groaned and buried her head in her bosom. You thought about getting a doctor or nurse, but you were frozen in place.

 

Sweetie shuddered as her back stretched and arched. The sleeves of her gown cinched against her biceps as her arms grew longer and thicker. As her breathing got heavier and faster small ripping sounds filled the room. Her gown was falling apart before your eyes with the ties along her back pulling apart and the seams around her shoulders slowly bursting.

 

Just how big was Sweetie Belle growing this time, you wondered.

 

Eventually, Sweetie Belle stopped shuddering. This attack seemed like it had lasted longer than the previous ones.

 

Pulling her head up, she looked different. She looked like a college co-ed with her thinner, sharper face. All the rips and tears in her gown had exposed her shoulders and back which were looking incredibly toned and muscular. And that was probably a good thing because Sweetie's breasts were pushing out farther than ever from her chest.

 

Sweetie Belle looked at you in a guilty fashion.

 

"Why is this happening?" she whispered.

 

You didn't know how to answer her so instead you suggested she stand up so you could see if there were any other changes. You helped the young woman out of bed, which was a bit of a struggle as she was a lot heavier than before.

 

Still getting used to her new body, Sweetie wobbled a bit and leaned against you. Brushing up against her you could feel that she wasn't quite as curvy as her sister, her bigger boobs not withstanding, but her frame was solid. When she rose to her full height you had to look up to see her face.

 

She was looking down on the top of your head!

 

It was at that moment that Rarity entered to see you standing next to her now amazonian younger sister.

 

Your girlfriend fainted so hard that she forgot to magically summon her fainting couch.

 

Later that evening the doctor came to administer the hormones. He warned that Sweetie Belle might experience hot flashes and other side effects, but she was a champ and didn't complain while taking the shots.

 

It was late, so you and Rarity both bid her goodnight and headed back to Carousel Boutique. You stayed the night because Rarity didn't want to be alone. Trying to reassure her, you reminded her that the hormones would probably stop Sweetie from getting taller like the doctor said.

 

What you didn't point out was the possible effects that a megadose of female hormones might have on Sweetie's out of control body.

 

---

 

You both showed up to the hospital the next day. The nurse intercepted you and directed you to the doctor. The physician had a slightly nervous look on his face.

 

"Ah, Ms. Rarity. The good news is that your sister hasn't grown any taller."

 

You could tell there was a 'but' coming.

 

"However, there have been other, um, changes. You should be prepared."

 

Rarity asked what kind of changes.

 

"Well, the hormones we administered seem to have been, um, amplified by her condition. You should probably just see for yourselves. Just be prepared for her to look different."

 

Concerned, you both headed to Sweetie Belle's room. When you entered, the tall figure sitting in bed was looking out the window and had the bedcovers pulled up to her neck. Her face was turned away from you and all you could see was a long waterfall of pink and lavender hair that was much longer and fuller than it was the previous night. Rarity cleared her throat and Sweetie Belle turned her shaggy head.

 

Frankly, you were astonished.

 

The woman sitting in front of you looked more like Sweetie's older, hotter cousin than the young lady you left last night. Her face was full and vibrant with luscious, pouting lips. It was hard to put you're finger on exactly why but she looked insanely hot.

 

"Hi Rarity. Hi Anon." Her voice was rich and smooth, like something out of a porn video staring a seductive teacher.

 

Rarity paused for a moment trying to absorb the changes in her sister. When Sweetie Belle started to get nervous, Rarity snapped out of it and encouraged her sister to stand up so she could get a look at her.

 

Slowly, very slowly, Sweetie turned her body so she could swing her legs over the edge of the bed. That was when you realized that Sweetie hadn't been holding the bedsheet up to her chest.

 

She was wearing the bed sheet on her chest!

 

Once she finally stood up you saw how the staff had used an entire sheet to craft the makeshift gown that covered her much, much bigger body.

 

Without a doubt the biggest thing about her was her breasts. Her temporary garment allowed you to see just how far Sweetie Belle's boobs now extended out in front of her. It was hard to believe but her massive mammaries were sticking out nearly three feet from her torso!

 

The draped cloth kind of obscured things but each breast seemed longer than they were wide. You also couldn't help but notice that the bumps of her nipples were poking through the fabric so you could also see that, as big as they were, they only pointed downwards slightly.

 

As she turned to the side you could also see that the rest of her figure had filled out quite a bit. Her hips were far wider than her shoulders and if the fabric hadn't been gathered around her narrow waist you might have assumed she had gotten fat.

 

But part of her that had gotten thick was her massive rear end! Her perfect bubble butt stuck out round and full. She was still massively top-heavy, but that booty was no joke.

 

Still, you tried to remain stoic. Sweetie Belle was just a girl after all, even if she did look like a walking fertility idol. Plus, she was your girlfriend's kid sister. In other words, you knew that you had to keep it together because Rarity was going to need your support.

 

They kept Sweetie in the hospital two more days to observe and make sure that she was stabilized. She did grow a bit more during that time, but nothing like she had.

 

When she was discharged Rarity brought some custom clothes she had made for her. A super baggy blouse made out of enough fabric for a full dress and a broad skirt fit her snugly. When you initially arrived in Equestria years ago the first thing that had blown you away was how abnormally large most women's breasts were. As you all left the hospital and Sweetie Belle struggled to walk while keeping her new assets from wobbling and bouncing all over the place, it became clear that even by Equestrian standards, Sweetie Belle's bosom was gigantic.

 

On the walk back to Rarity's place you wondered aloud if you shouldn't have called a cab. It wasn't a long walk from the hospital but Sweetie Belle was clearly struggling with her balance and gait. Plus your path ran right through the middle of town and lots of people were beginning to notice the enormously endowed beauty that you were escorting.

 

To your surprise, Sweetie herself nixed the idea. She was determined to make it back under her own power and you admired her fortitude. How she was even able to stand upright when each of her boobs was bigger than her torso was a mystery to you. But maybe not that big of a mystery; you glanced down at her back and saw well defined core muscles flexing through the tight fabric of her shirt. Glancing up at her exposed biceps and triceps you wondered absently just how strong this girl was now.

 

As you rounded the corner to Carousel Boutique you heard a pair of young voices address your girlfriend, one raspy and one twangy. As expected, Sweetie's partners in crime had shown up.

 

"Hey Ms. Rarity have they let Sweetie Belle out yet?" Apple Bloom asked.

 

"Yeah! It stinks that they won't let us go see her!" Scootaloo added.

 

Frankly, you were glad that the two little hellions hadn't been allowed to invade the hospital. As Sweetie Belle came around the front of the building Rarity gestured towards her.

 

"All right girls, calm down. She's right here."

 

The two Cutie Mark Crusaders looked to either side of their much bigger friend and started to ask where Sweetie Belle was. Then they stopped and looked up.

 

And up.

 

And up.

 

You could almost hear their brains breaking as they looked on in shock. To be fair though, in less than a week their BFF had gone from their height to six feet, eight inches tall.

 

"Swwwweeee... Sweeeee... SWEETIE BELLE?!" Both Apple Bloom and Scootaloo squealed.

 

Sweetie Belle blushed and tried to fold her arms across her chest but found that she couldn't. You had been impressed with how nonchalant she'd been acting for the past few days as multiple specialists poked and prodded her. This was the first time you had seen her truly get embarrassed since that first night in the hospital when she had asked if you thought she was cute.

 

Fortunately, Rarity interrupted just as Apple Bloom and Scootaloo started peppering the bashful girl with questions.

 

"Now now, you can talk all you want inside. We're starting to draw a crowd."

 

You looked around and saw villagers slowing down to gawk and rubberneck. Rarity ushered everyone inside while you gave a couple of guys who were loitering the stinkeye.

 

You made lunch while Sweetie Belle and her friends went to the parlor so she could relate what happened to her and her experiences in the hospital. While you made sandwiches Rarity wandered in. She gave you that tired little look that meant she was grateful for your help and toyed with a tape measure draped around her neck.

 

"Sweetie has been such a trooper but I can tell she's near her limits." Rarity sighed. "After lunch I'll need to measure her again if I want to make her some proper clothes. I just hope she's finally done growing! She..." Rarity was interrupted as Scootaloo came racing into the kitchen.

 

"Rarity, Anon, can you come here? Sweetie's crying."

 

All three of you entered the parlor to see Sweetie Belle sobbing and brushing off Apple Bloom who was trying (and failing) to console her. Apple Bloom looked up guiltily.

 

"We were just talking and she..." she gestured helplessly.

 

Rarity gracefully swooped in and started ushering Sweetie towards the stairs.

 

"I think we've all had a long day. Why don't you girls head home, alright?"

 

Both girls looked guilty as their fellow Crusader went to her room.

 

"Don't worry about it girls," you reassured them. "Sweetie's just tired and cranky. You shouldn't take any of that personally."

 

What you didn't add was that Sweetie Belle's crazy hormones were also to blame. According to the doctor it was like combining the mood swings of a pregnant woman with a woman going through menopause. It was like a perfect storm of temperamental female moodiness.

 

Could there be anything more terrifying?

 

You escorted Scootaloo and Apple Bloom to the door and made sure they were okay. When you re-entered the parlor Rarity was waiting for you.

 

"I put her to bed," Rarity said. "The poor dear, at least her friends are supporting her." Then she frowned, "I just hope they can continue supporting her."

 

"What do you mean?" I asked.

 

"I mean, things are going to be different for Sweetie Belle now. She looks like a grown woman! I'm afraid it's going to be hard for her to adjust to all the unwanted attention she'll get. Especially with her new figure."

 

Your girlfriend patted her own extravagant bosom.

 

"I remember when I was a girl and I began to fill out. I was terribly excited but it was also sort of scary. But I had years to get used to my endowments. Sweetie's had everything thrust on her all at once!"

 

Rarity was starting to freak out; not a major freakout, just a small Rarity-freakout. Fortunately you knew how to handle one of those.

 

"Look sweetheart, this town is a nice place and she has a good support system. Every group of kids has its early bloomer. Sweetie is just an extreme example."

 

Truth be told, you were a bit worried too but Rarity seemed to accept what you were saying.

 

"Come on, let's eat something and I'll take Sweetie some food in a few hours"

 

Later that evening you prepared a plate full of sandwiches and took them to Sweetie's room. In the hospital you'd learned that she had an out-sized appetite to go with her out-sized body.

 

You knocked on Sweetie's door. Inside you heard a small cry of surprise. Concerned, you asked if everything was alright. A slightly panicked voice asked you to hold on a moment.

 

It was still weird to hear Sweetie's new voice. In fact, of all the changes she had gone through it might have been the hardest one to get used to. You were used to a high pitched, slightly squeaky Sweetie voice and now her tones were smooth and a little husky.

 

Eventually the door opened a crack and the big girl peeked down at you.

 

"Uh, I brought you some food." You held up the sandwiches.

 

Reluctantly, Sweetie Belle opened the door to take the food. A musky smell hit you and Sweetie's face was flushed. Glancing down at her bed let you see the mess of bed covers. And... was that a damp spot on the mattress?

 

Oh, no.

 

Nope, nope, nope, nope!

 

You did NOT just walk in on your girlfriend's kid sister getting herself off. When you looked up from the bed Sweetie was watching you.

 

Crap.

 

Trying to ignore the incredible awkwardness of the situation you handed her the sandwiches and made to leave.

 

"Wait, Anon!" Sweetie Belle reached out and grabbed you by the hand.

 

You lurched to a halt. Holy cow, this girl was strong; her grip was like a steel trap. After she stopped you getting away, however, she didn't know what to say.

 

"Um, I, uh, I just was... I..."

 

You patted the hand that was holding you and tried to put on a comforting face.

 

"Look, Sweetie. I'm not gonna tell anyone. Besides, we all have needs. Don't ever let anyone try to make you feel guilty about this kind of stuff. Especially after what you've gone through. Okay?"

 

You must have been batting a thousand when it came to comforting females because Sweetie immediately looked relieved.

 

"Thanks Anon."

 

You smiled softly and looked down. Now it was your turn to blush as you realized she was wearing the same shirt from earlier. Several buttons were undone and she was showing off several feet of soft cleavage. It made sense that she would wear that shirt to sleep in since nothing else fit her and you doubted she was used to sleeping in the buff, but damn it was distracting.

 

Unfortunately, Sweetie noticed where you were looking. She didn't get embarrassed though. Instead she gave a small smirk, as though she was enjoying your discomfort.

 

She let go of your hand and turned to set the sandwiches on her nightstand. As she turned, her boob-shelf turned out of the way too and no longer blocked your view of her lower half. You could see how snug the light purple shirt was around her trim mid-section.

 

You could also see that she wasn't wearing anything else besides a pair of satin panties. As she bent over slightly to set the plate down her massive posterior peeked out from the bottom of her shirt tails. The three diamond mark on the cloth showed that the pale panties must have belonged to Rarity. But though your girlfriend herself had a pleasingly plump posterior, the underwear was clearly too small for Sweetie Belle. The clinging cloth cinched up between her big round cheeks, not quite making a thong but definitely showing off the goods.

 

Ohhh, this was not good.

 

Sweetie turned back around with that little smirk still on her face and sauntered back over to you. Her hands were clasped behind her back and in any other circumstance she would have looked rather innocent and girlish. But when that pose was combined with gallons of jiggling boob-flesh barely contained in a shirt that was thin enough to show off her long, fat nipples, innocence was the last thing on your mind.

 

Mesmerized by her cleavage, you didn't realize that she was coming in for a hug until she had her long arms around you. She crushed you to her, powerful arms pulling you into her plush pillows. It was a good thing you were so tall; if Sweetie pulled this move on Rarity you were certain she would be completely smothered! Sweetie leaned forward, snugging you even more into her bosom. She giggled, her immature laugh at odds with her silky, sultry voice.

 

"You know Anon, I was thinking being so tall would be terrible. But I kind of like how small and cuddly you are. I mean, all the boys at school must be even smaller." She jerked back, releasing you.

 

"Oh my gosh! Do you think that will make it harder for me to get a boyfriend?" she said in a panic.

 

Recovering from her squishy frontal assault you said the first thing that came to mind.

 

"I don't think so. I'm sure there are a lot of guys who like big girls."

 

Again she gave you that mischievous smirk.

 

"Like you, Anon?"

 

"Maybe," you laughed, "But I'm already taken."

 

The giant schoolgirl leaned forward to look you in the eyes. You swore you could hear the buttons on her shirt creak ominously.

 

"Humph! Like she could stop me if I wanted to steal you away."

 

Uh oh.

 

"Um. But if you did that then you be a boyfriend stealer, and nobody likes those."

 

Sweetie frowned petulantly, "Yeah, I guess so..."

 

Yup, despite her mature body she was still a innocent girl at heart. Speaking of which...

 

"Besides, you're a little young to be worrying about a boyfriend, aren't you?"

 

Sweetie Belle put her hands on her hips and struck a confident pose.

 

"Oh, I don't know. Everyone tells me I'm very mature for my age!"

 

She puffed her chest out proudly, only this time one of her buttons actually did burst off her shirt!

 

"Eek!" Sweetie cried as she hunched over to cover her spilling cleavage.

 

You couldn't help but laugh.

 

"Why don't you worry about finding something that fits before worrying about boys, eh?" She stuck out her tongue as you left.

 

In the hallway Rarity asked how her sister was doing.

 

You considered telling her that once Sweetie figured out how to use her sinful new body she was going to be absolute hell on any and all males in town and their poor girlfriends.

 

Instead, you smiled and said, "My dear, I think Sweetie will be just fine."

 

The end.
