Runneth Over

Appearing with a flash of light and pop of displaced air within the Carousel Boutique, Celestia opened her eyes. The shop was dimly lit and vacant, bereft of customers or employees, though she wasn’t paying a visit at such an odd time for no reason. As her ears perked up at a noise coming from the employee area behind the counter, she grinned.

“Knock knock,” she called out.

“Just as expected, you’re right on - goodness gracious,” Rarity gasped, trotting out from her studio and coming to a screeching halt.

Celestia’s cheeks darkened as the couture stared over at her open awe. There was a very specific reason she’d explicitly asked Rarity to come after hours for her order, but she hadn’t been as forthcoming with details as she could have been. While she had told her friend that she was pregnant and that she’d be requiring some new maternity attire, she’d failed to explain why she desperately needed a few new garments.

Glancing over at a standing mirror, she sighed. She was positively gravid, her stomach so large that one could easily assume she was carrying triplets, and her breasts - heavens be, her heavy, milk-laden bosoms were the size of small beach balls! Each gargantuan breast was engorged and virtually spilled out of the makeshift toga she’d fashioned for herself, and she knew they’d only get larger as time progressed.

To make matters worse, as if having an even larger rack and huge belly didn’t complicate life in the Crystal Empire, she’d put on a considerable amount of weight. Her tush was bigger and softer than ever, devouring even her most conservative panties and transforming them into thongs, while her pudgy thighs strained any leggings or stockings she slipped on. She’d known it would only be a matter of time before doing some clothes shopping, but even she hadn’t realized how quickly her wardrobe would require new additions.

“You failed to mention that you were in - Ahem - such a state,” Rarity falteringly clucked, struggling to compose herself as she trotted over to her.

Turning in place, she lowered her gaze past her heaving bust. “Yes, w…well it’s a bit complicated.

Rarity peaked a brow and scrunched her snout. “Complicated. Darling, you’ve had at least seven months to -”

“Two weeks,” Celestia interjected, simultaneously amused and embarrassed by the mare’s stunned expression.

“I…h…how - two weeks?” Rarity croaked. “There’s no possible way that -”

Blushing harder than ever, Celestia held up a hand. “I wouldn’t lie to you, Rarity. As silly as it may sound, this,” she explained as she caressed her abdomen, “is the result of, shall we say a bit of overzealousness on my and Cadance’s behalf…”

Rarity reluctantly turned and waved for her to follow. “I would never assume you’d lie to me, Celestia - be that as it may, I’m curious about…”

Trotting along after her, Celestia uneasily chuckled. “About how this happened?”

“Quite,” Rarity whispered, pressing into her workshop and over to her drafting table.

Celestia walked in and veered slightly to her right. Coming to a stop at an open area of the floor, she grunted and ran a hand over one shoulder and to the knot securing her improvised attire. Wearing a bed sheet around, while comfortable and serving to retain her modesty, wasn’t the most elegant way to dress, but it was the only option she had.

“It’s not that grand of a story,” she began, shrugging the toga off herself.

While Rarity prepared, flitting about to gather measuring tape, pinking shears, and a few bolts of fabric, she recounted the passionate and admittedly ambitious scheme Cadance and her had enacted. Rarity, much to her credit, remained silent throughout most of the tale, until she sauntered over with a cart laden with the tools of her trade.

“I’m not that surprised that you and Cadance would want to be mothers again, although you seem to have gone a bit overboard - no offense,” Rarity laughed.

Celestia extended her arms to her sides and held still as the mare levitated a stepping stool over. “None taken, but you know what they say about hindsight being twenty-twenty.”

“Hold this,” Rarity instructed, holding the end of her measuring tape to Celestia’s naval. “I presume the maternity ensembles I fashioned for you have long since been discarded?”

“It’s been roughly two decades,” Celestia pouted, turning her head to watch the mare circling her. “For the record, I didn’t discard them.”

Coming around to her front, Rarity completed the one measurement and jotted it down on her clipboard. “Charity then?”

Celestia nodded. “Actually yes. The proceeds went to a hospital.”

“Well I hope they went to the maternity wing,” Rarity laughed as she stepped onto the stool.

Snickering at the joke and genuinely wondering if some of the funds went for such an apt purpose, Celestia held still. It was far from the first time she’d gotten a fitting, and it assuredly wouldn’t be the last, yet having her bust measured was always a bit of a delicate affair - especially under such unique circumstances. Keeping her arms extended out to either side, she watched Rarity struggle to wrap the tape around her expansive chest.

“Would you like me to…?” she let the question hang and shivered as the mare’s face practically disappeared into her cleavage.

“Mph nnnnf mmph nf!” Rarity replied, her words muffled by the exorbitant amount of breast meat surrounding her head. She ultimately pulled away with an exasperated look and pursed her lips. “Are they even bigger than last time? I could swear they weren’t this prolific.”

Prolific - the word resonated with Celestia and sent a shiver up her spine. Several days prior, she’d realized exactly why her bosoms had ballooned to such an absurd size. Recalling how Shining had discovered that, irrespective of how early in her pregnancy she was, she had already become as productive as a dairy cow, she glanced to her right nipple.

Right on cue, seemingly knowing it was being looked at, the delicate bud of rigid flesh leaked a drop, then a small stream of milk. Fantastic - just wonderful. She wasn’t particularly bothered by showing her bare body to a professional like Rarity, but spontaneously lactating while having her measurements taken was a bit awkward.

Rarity stiffened as small jets of milk sprayed from one teat and then the other, showing the floor to either side of her. “Stain resistant, waterproof, and with adequate dimensional folding to accommodate some growth,” she murmured as she scribbled upon her notes.

“Extensive growth,” Celestia added. “Considering I’ve got months ahead of me, I’d much rather err on the side of caution when it comes to my attire. I do have a question though - that dimensional folding you mentioned, might you teach me how to do that?”

Peeking up at her, Rarity smiled. “Of course, darling! It may seem like a complex enchantment, but it’s actually shockingly simple. After we’re finished up here, I’ll jot down a few notes and fetch you a book detailing the process.”

“I’d appreciate that,” Celestia mused as an idea began to coalesce. “Just to be sure, you should double the space for my bust…”

“Double - no, quintuple the space,” Rarity stated as she rewrote and underlined the last line she’d jotted down. “It couldn’t hurt to -”

Grrrrrrr

Celestia froze and her attention sailed downward and to the source of the sudden noise. With a flustered expression, Rarity anxiously laughed and batted a hand. No way - there was no way that the two fountains of milk showering from her breasts had given the mare hunger pangs ~ could they? Entertained by the notion that she’d unintentionally triggered the normally demure mare’s appetite, she clutched one of her tits in both hands and gave it a small squeeze.

The flow of her milk amplified into a geyser, practically pouring from the held bosom while she giggled. “If you’re feeling peckish, you could - you know…”

She’d merely meant it as a joke, seizing the moment to fluster her friend and break the tension from what would otherwise be a somewhat uncomfortable moment, but her plan backfired spectacularly. Instead of brushing off the offer or making light of the situation, Rarity licked her lips and gazed longingly at the gushing bud of flesh. Though she should have stopped things there and urged the mare to continue where they’d left off, the thought of being nursed upon made her marehood wink.

“I…I mean…” Rarity trailed off, struggling to avert her gaze while she rubbed the back of her neck.

Angling her tit over and relaxing her grip, Celestia giggled. “Come now, it’s not like Shining or Cadance would mind - besides, I’d rather somepony drink it than let it go to waste.”

She stepped back, released her breast, and brought her forearms together over her chest to press her bosoms together. To Tartarus with it - she’d done more scandalous things over the millennia than letting a friend nurse from her. Playfully swaying her shoulders from side to side, she mutely pressed her offer.

“Oh buck it,” Rarity halfheartedly groused. Closing the small gap between them, she paused, looked up, and lifted a finger. “Not a word of this to anypony ~ promise?”

“Only if you swear to do likewise - oh and don’t be shocked if I make a bigger mess,” Celestia whispered, sensing an ache steadily growing in her loins.

Being pregnant, regardless of at which stage, was a blessing and a curse. The added weight, bizarre cravings, and occasionally sore feet weren’t that bad, but her insatiable libido could and at times had caused a number of problems. She’d had all sorts of wild experiences throughout her life, although there were few things more torturous than having to maintain her composure throughout a meeting while being painfully aroused.

“Very well,” Rarity responded, “but you’re going to help clean afterwards.”

Celestia nodded and sent power surging into her horn. If they were going to indulge themselves in such a spontaneous way, she wasn’t going to cut any corners. The golden aura surrounding her clit and radiating into her depths went unseen, but it would be just the thing to let her fully enjoy a pair of luscious lips upon her.

Casting her reluctance to the side, Rarity stepped back onto the stool, leaned over, and latched onto her nipple like a starved child. She wasn’t sure what was hotter - the fact that her friend and a hero of Equestria was sucking on her breast or that it felt absolutely amazing. Her tits had always been a weak point of hers, and she loved having them played with while making love to either Shining or Cadance, yet they became leagues more sensitive when she was lactating. Surreptitiously using her magic to get herself off, she slipped a hand to the back of Rarity’s head.

As she closed her eyes and savored the blissful sensations washing over her, her thoughts drifted into amorous waters. She couldn’t say if things would stop with Rarity nursing on her, but she hoped they wouldn’t. The relationship she had with Shining and Cadance was somewhat open, allowing them to include a fourth in the bedroom at times, and she wouldn’t be opposed to bedding an Element of Harmony.

Regardless of how things played out at the Carousel Boutique, the morning was a reminder of the long, lustful road ahead of her. Shining had been lucky all those years ago, essentially only having to deal with one gravid, horny Princess at a time, but now he was going to have to weather the advances of Cadance and herself for the better part of a year. Fixating on the passionate night she’d been knocked up, she softly groaned.

Glancing over at a nearby mirror, one that appeared to have been pulled from a dressing room, she marveled at the spectacle she was making. Rarity was voracious, gulping down mouthfuls of milk like she hadn’t eaten in days, and the bottom of her blouse was already rounding from the impromptu meal. Refocusing her magic just a touch, if only to make her host a bit more comfortable, she unbuttoned the mare’s shirt and pants so she would give herself a bit of a peep show.

The view was spectacular. Rarity’s soft, gradually rounding belly and bra contrasted sharply against her curvaceous physique, but that wasn’t what drew her eye. Her areola, normally a light pink, had darkened and grown considerably since she’d begun producing. Now larger than a pony’s head, the dark, delightfully tender patches of skin on her tits stood out more prominently than ever.

Rarity lifted an arm, pawed at her free breast, and lovingly pinched her unaccosted nipple, causing her faint moan to elevate into a whimper. The normally reserved seamstress knew exactly what she was doing, and the added bit of stimulation was just the perfect complement to the staggeringly lecherous exchange. As she tightened her grip and weaved her fingers through the unicorn’s mane, a smile split her muzzle. Yeah, the next couple of months were going to be very, very interesting…
