“BRRRRRR,” shuddered Sweetie Belle, as another cold blast of wind blew through the open window.

She would have liked to have kept it closed, but then the room would quickly heat back up again. So for now, she was content to just sit upright in a chair, her enlarged chest resting in her lap, as she looked over the natty book in front of her.

I can’t wait for finals to be over with, she thought.

As she adjusted herself in her seat, she was also thinking about how good it would be to get back to Ponyville for Hearth’s Warming Vacation with her friends, and just relax. She was also eager to see Rarity again, since her post-Halloween growth spurt had caused her to grow a number of extra inches. Now, even the turtleneck sweater she was wearing felt like it was constricting around her ample bosom even more than usual. Looking around the room, she shrugged her shoulders before removing the top, and leaving her breasts encased in her overflowing bra. The cool air from outside felt nice on her shoulders.

As she reached over to write some notes, she felt like something was a little…strange. A few moments later, she felt a pinching sensation in her bra cups.

“Uh-oh,” she said, pushing back from the desk, and bouncing into the bathroom.

Her mirrored reflection confirmed her fears. The slightly-fuller bra, had now become even fuller! She could even hear the straps of her bra stretching, as her bosom pushed outwards.

“I better get this over with,” she sighed to herself, unhooking the rear straps. “Don’t want to end up like I did in Chrome’s place.”

As she peeled off the cups, her left hand flew to her darkened left nipple. However, as her fingers began to give it a tug over the sink, her eyes returned to her reflection, and stopped.

Like two balloons being inflated, she could visibly see her breasts growing before her very eyes. As she looked at their swelling forms, her fingers pulled away from her nipples, and she found her hands cupping the enlarged undersides of her udders.

She had touched her breasts before, but she could swear they were never this…sensitive! As her hands rubbed and stroked over the rounding shapes, she felt herself gasping as a tingling sensation shot through her body.

“Oh Celestia,” she gasped, surprised at the sensation.

A few moments later, she was back in the main dorm room, sitting on the edge of her bed, as a naughty thought passed through her mind.

“Maybe…just for a little bit,” she said to herself. “That can’t possibly hurt.”

Crawling over to the window, she shut it tightly, before closing her eyes and lying down on her bed. She was low enough below the window, that nopony could see what she was doing…or about to do.

As her left hand massaged and rubbed against her still-swelling left breast, her right hand made it’s way under her light-green panties.

Sweetie closed her eyes, as her fingers found the delicate folds of her vagina. A long moan escaped her lips, as the jolt of sensitivity from her breast fondling, combined with her sensitive ponybits, caused her to breathe harder.

She had pleasured herself many times before, but the tingling she usually felt in her nether regions, now seemed to be all over her body. As she focused on the overwhelming sensations, she was unaware of what was happening close at hand.

BRUHM-M-M-M-M

The sound of wood sliding on the floor caused Sweetie Belle’s eyes to snap open. Her first thought was that the hallway door had opened, but as she tried to sit up, her eyes suddenly encountered an expanse of white, which she soon realized belonged to her!

Whereas her breasts had been the size of large basketballs when she had started to play with herself, her chest was now so big it blocked her view of the room, except for a portion of the ceiling! Over to the right, she could see the source of the noise, as her right breast had grown so much, it had shoved Applebloom’s bed into the wall!

As she tried to grapple with how long she had been pleasuring herself to ignore such expansive growth, she attempted to move, but found herself unable to budge the immovably-huge ponybumps!

I gotta get help, she thought to herself. If this keeps up, I’m gonna get squashed by my own breasts!

Pulling herself over to the window and opening it up, she looked down on the numerous stallions and ponies walking about, and suddenly felt herself panic. She wanted to call for help, but she couldn’t help but realize the mess she was in.

What if someone sees me like this? She thought. I’ll be the laughing stock of Canterlot University if they find out.

Nervously, her green eyes darted to the massive white mounds rising towards the ceiling, before returning to the open window. At that moment, she happened to notice a familiar dark-blue stallion, in his purple-and-gold letterman jacket down on the walkway.

“Hey!! Chrome Shield!” she called out, waving her right arm. Several other ponies on the sidewalk looked at her window, but fortunately, Chrome did as well.

“Hello!” He called out. “Studying hard?”

“Kinda,” she replied. “Say, could you come on up here? I…need some, study help.”

“Sure,” said Chrome. “Be right up!”

“Please hurry,” she called after him, as he trotted over to the entryway.

A few moments later, Chrome found himself outside a familiar door. Turning the handle, he found it wouldn’t budge.

“I think it’s stuck,” he called out.

“Just push really hard,” came a muffled voice from the other side. “If you hear anything…odd, just keep pushing.”

“Um…okay.”

Turning the knob again, he shoved as hard as he could. From behind the door, a pained moan was heard, as the opening door revealed a huge white mass, of which the door was carving out a little area for him to enter into!

“Wh-what happened?” He called out.

“Just shut the door!” she moaned back. “Follow along the wall to your right.”

The white mass forcefully closed the door, and Chrome almost found himself suffocated by tit-flesh! Sidling his way along the wall, he tried to ignore the moans from Sweetie Belle as he pressed against her unrecognizable breast. Eventually, he made his way to a corner of the room, then past the open bathroom door, before he emerged into the corner by the window. Seeing the masses of titflesh protruding from Sweetie Belle’s chest into the space in front of her, made him gulp nervously.

“Did this happen while you were sleeping again?” he asked.

“Um…not actually,” she said, looking nervous. “I…kinda wondered…how big they would get if I didn’t…milk them?”

“No offense, Sweetie Belle, but that was a really bad idea-“

“I know, okay!?” she retorted back at him. “I know and I’m sorry, now can you just please help me!?”

“Okay-okay,” replied Chrome, trying to not think of the bulge that was growing between his legs. “But this isn’t gonna be easy.”

Suddenly, there was a loud clatter across the room.

“What was that?” asked Chrome.

“I, think I knocked over the toaster in the kitchen,” blushed Sweetie.

“Actually…this may work better than I thought,” he replied. “I got an idea. Try to stay calm.”

“What are yo-OH!” shuddered Sweetie, as Chrome made his way back the way he had came.

This time, he made his way past the hallway door, until he soon came across a wooden countertop against the wall. Squeezing past it. He was confronted by the sight of Sweetie Belle’s left nipple, it’s areola at least 3 1/2 feet high, and it’s dark rubbery nub bigger than Chrome’s head.

Chrome could feel the erection in his slacks getting incredibly uncomfortable, as he slid past the thick nipple, hearing a loud moan on the other side. Once he brushed past it, he found what he was looking for: the kitchen sink!

“Sweetie Belle!” he called out. “Can you hear me?”

“Y-yes,” came a breathy sigh from across the room.

“Okay, I just want to warn you, this may get…messier and, feel a bit different than when we did this in my apartment. Fortunately you have a sink, so that’s one good thing we got going for us. Oh, and you might want to close the window.”

A few moments later, Chrome heard the sound of the window closing, and found his hands struggling with the huge left nipple. Trying to get his tiny hands around it was near impossible, and in the end, he ended up grasping the flesh tightly, and pulling as hard as he could, until he managed to get it close to the sink. Taking a few deep breaths, he tugged and squeezed as hard as he could, and a few seconds later, a powerful jet of milk shot out of the huge nub, hitting the sink with enough force to ricochet back at Chrome, drenching him from head-to-waist.

“Okay,” he called out, “this..is going to be even messier than I thought.”

And so it went.

After some time, Chrome soon found that if he held each of Sweetie Belle’s nipples in a “choke-hold” maneuver, he was able to not only get a better grip, but coax more milk out of her ponderous pontoons.

Try as he might to aim for the sink, a good majority of milk was soon dripping off the kitchen cabinets, and Chrome himself. After being spurted with about 6 gallons of milk, he finally threw off his jacket. A few moments later, his soaked shirt joined the pile of soggy clothing.

It took some time as he alternated between each breast, and Chrome’s forehead was noticeably sweaty, when he realized that the distance between the nipples and the sink was getting wider!

“Sweetie Belle,” he called out. “You’re getting smaller!”

“R-really?” he heard her moan. “I, I don’t f-feel smaller.”

“You are, trust me. Listen, I need you to move off the bed and towards me. It’s easier if we keep you by the sink so I can drain you.”

“O…okay.”

And so it went.

Chrome would tug and drag the huge tits back to the sink where he would continue the milking process, while trying not to think about Sweetie Belle moaning on the other side…or his strained boxers and pants.

As time passed, the sky outside the window dimmed to a fiery orange. Soon, the last vestiges of the flaming golden ball had disappeared courtesy of Princess Celestia, and the bright sphere of the moon could be seen.

Back in the dorm room, the main light had been turned on. While most of the furniture had been pushed aside, Sweetie Belle was now leaning over the sink, her now beachball-sized bosom on it’s edge, as Chrome continued to milk her. Fortunately, her nipples were almost back to normal, and he could now get his hands around them. A few moments later he stopped, and dropped down to the floor.

“Are you okay?” asked Sweetie, before gasping as the weight of her chest almost sent her onto the floor.

“I need a break,” he replied, flexing his aching arms. “I’m not used to that much work.”

“So, did I give you quite a workout today?” chuckled Sweetie.

“…I think we need to be serious for a moment,” said Chrome. “Do you realize the kind of trouble you could have been in?”

“Well, yeah, but fortunately you were here to-“

“But what if I wasn’t here?” He replied, sharply. “Applebloom and Scootaloo weren’t here either. Would you have asked anyone else to help you?”

“…um…no?” she blushed. “Because it…it might have been embarrassing-“

“So basically, you didn’t think,” sighed Chrome. “Sweetie Belle, how could you be so stupid-“

It was then that Chrome saw liquid pooling in the corners of her big green eyes, and he took a deep breath before continuing.

“Look,” he replied, “I’m…sorry I got upset but…you need to make sure that you don’t let this happen again. I just…don’t want you to get hurt, okay?”

“Okay,” she replied, meekly.

“And…the least you can do is go to the local hospital after this for a check-up.”

“Why?”

“Maybe they can prescribe something for you to stop this. Plus, at the very least, maybe you can ask them for a classroom exemption notice.”

“For what?”

“In case this happens during class. I think today proved you need to be prepared if this happens at anytime. Can you please do those things for me? I’ll…sleep a little better knowing you’re taking care of yourself.”

There was a moment of silence, before Sweetie Belle gave him a little nod.

“Alright,” she said. “I’ll make an appointment tomorrow.”

“Pinkie-promise me you will,” he said.

“Cross my heart and hope to fly, stick a cupcake in my eye,” she replied.

The recitation and her actions caused Chrome to chuckle a little, before he got back on his hooves, rotated his arms a few times, and returned to his milking duties.

“I’m holding you to it,” he said after a few more spurts.

“Sir, yes sir!” replied Sweetie, clopping her hooves together, and saluting him.

“It’s not necessary to salute. Say, you don’t have an extra shirt that might fit, do you? I don’t feel comfortable wearing a milk-soaked one across campus.”

“I think Applebloom might have something that could work,” she replied. “Maybe once we get me back down to a decent size, I can give your jacket and shirt a washing. Can you believe this is the second time I’ve done laundry for you?”

”Hey, I’m not one to complain,” chuckled Chrome. “If you want to wait a little bit, I can bring over the rest of my laundry for you to-“

Suddenly, there was the sound of keys in the doorknob, which caused the two to go quiet.

A few moments later, the door opened, and Applebloom and Scootaloo walked into the room.

“Fer Celestia’s sake, Sweetie Belle,” said Applebloom. “Ya gotta remember to lock the-“

It was then that the yellow and orange ponies stopped in the doorway. Their eyes took in the furniture pushed against the walls, the milk-soaked kitchen area, Sweetie Belle’s huge chest perched on the edge of the kitchen sink, with a shirtless Chrome Shield frozen midway through milking her left breast.

“Wh-what hap…what’s going on!?” Scootaloo managed to eek out.

“I’ll explain in a minute,” replied Sweetie Belle, a deep blush spreading across her cheeks. “In the meantime, can you two please help Chrome out? He really needs a break.”

Author's Note

Been out of commission, trying to deal with real life. The other night after a conversation, felt I had the spark to write out this chapter.

One difficulty was coming up with why Sweetie Belle would let herself get so big. Curiosity just seemed ridiculous, but then the idea of pleasuring herself seemed to work on getting her so preoccupied, she wouldn’t realize what was happening.

Stories like this can sometimes get monotonous, so it helps to get creative in trying to keep it entertaining.

Like most chapters, I wondered if I could come close to my 2500 word maximum, and was able to do so.
