Rarity's Potency
🕑 Added 2023-10-04 12:04:40 +0000 UTC“Now, dear, if you could just hold still,” Rarity said as she slung the measuring tape around Fluttershy’s hips. “It won’t take a minute.”
“I’m trying,” Fluttershy insisted, even as she squirmed away from the seamstress’ touch. Or rather, the tremendous set of bulges that not so much poked into Fluttershy’s side as if threatened to envelop her entirely between them.
Rarity was a lot of lady to take in all at once. She was tall, leggy, and so ridiculously endowed that it was a running joke around town that she had made some infernal pact to be able to fit it all inside her elegant creations, much less being able to work so seamlessly around it. (Nonsense, Rarity insisted; demonic magic could not possibly hope to beat her skill with a needle for creating her compression wear.)
As it was, the purple-maned pony wore a chic pants suit that overflowed with cleavage, her breasts so large that Rarity could stick her arm out straight ahead and still not reach halfway to her nipples. The bulges between her legs were somehow even more outrageous, confining a cock several times the size of its owner and only Celestia knew how many pairs of ultra-virile balls besides. She could make anybody in Ponyville blush; no wonder Fluttershy twisted herself into knots at such close proximity.
But Rarity was not pleased. “Really, dear, I can’t work if I don’t get a good measurement. Is something distracting you?”
Fluttershy’s face was past turning crimson; the color looked more like to become a permanent fixture. She could hear the gurgling of Rarity’s nuts, like the rumbling of a distant waterfall. A waterfall that inexorably grew louder…
“Uhm…”
“Hmm. Let’s switch it up a bit.” Rarity’s measuring tape whipped around Fluttershy’s bust instead, squeezing her generous breasts. “Oh my, you’ve been growing, haven’t you? Good. We can get you a nice, low neckline to show that off.”
Fluttershy fidgeted with her hands. She didn’t speak, but her nipples grew hard against the tape.
“That’s a yes, I take it.” Rarity smiled. “Let’s just… Ah? You’ve got more for me?”
As Rarity held the tape close to read off the measurement, Fluttershy’s breasts pushed it out another inch. And another. And another. There was no question that her boobs were growing, and it made Fluttershy fidget even harder, looking away from both her chest and Rarity’s knowing eyes.
“That looks like a yes. I’m glad you’re excited, dear, but perhaps you could have gotten all of this out of your system before you came here for your measurement? Busting out of your top is good, clean fun, but you need to be able to put it on in the first place.”
“I’m not…” Fluttershy started, biting her lip. “Not d-doing anything…” Her breasts continue to swell, cup-size by cup-size. As they outgrew her head, she covered her chest, twisting around Rarity’s fat cockbulge with a pleading look on her face. “Rarity, I think… something’s wrong.”
“Now now, there’s no need to be embarrassed. Better you get it all out now. You’re a growing girl, I get it. I’ve been there.” Rarity allowed herself a little grin. “I am there, in fact.”
“No, that’s not what I—” Fluttershy whimpered, her words interrupted by a sudden, breathy moan. “Not what I meant!” Her breasts were growing quicker, now, as were her hips, her lovely figure blooming before the seamstress’ very eyes. Fluttershy could not stop touching herself, rubbing her increasingly plump thighs together as her body tensed and her eyes rolled back. “Oh, fudge!” she called, gushing a stream of hot, fragrant girlcum down her legs.
Rarity raised an eyebrow. “Huh. Well, if that’s what it takes for you to get it all out, then who am I to judge? Mind the spray, please.”
But Fluttershy was beyond caution. “R-Rarity!” she gasped, breathing hard as another orgasm rolled through her. Her cunt bulged between her legs, growing fatter with every messy squirt of juice that splattered across Rarity’s shop, staining floor and fabric in equal measure. Her breasts kept swelling, overflowing her arms as they, too, painted the shop with voluminous streams of milk. And there, pushing them up, was her belly, taut, round, and indisputably pregnant.
“Ah,” Rarity said in the calm tones of a gentleman detective, “I see what’s happening. Did I…?” She cast her gaze down to her tremendous crotch-bulge, running a hand over the smooth fabric until she found it: a torn seam.
She looked up at her by now constantly cumming friend “Apologies, dear. Seems I have a leak. You know how it is.”
Did Fluttershy ever. Unprepared exposure to Rarity’s sex was not to be taken lightly. By now, she was pregnant with hundreds of the studly seamstress’ foals and she hadn’t even touched it. But all that close contact was having an effect, even as Rarity took her time to decide if she should blow off some steam or not. The yellow pony’s big, enticing breasts rubbed over Rarity’s clothed bulge, which rumbled ominously and stretched her already straining outfit with another dozen feet of meaty mass.
Another seam popped.
And Fluttershy moaned, her mind wholly occupied with the dominating presence of Rarity’s cock. Her belly bloated rapidly, tits and ass swelling as if they had no other choice, and she threw herself around Rarity’s neck with no more wishes than to be fucked and bred further by her divinely hung friend.
“Well,” Rarity said as her cock steadily filled her shop, growing through even her carefully crafted compression wear. “It’s going to be that sort of session, is it dear?”
The air filled with a steamy musk, a pungent scent so strong that any pony around her would have to submit. But there was no need. Outside her shop, there was nothing but moans and gasps, a cacophony of sudden orgasms as the whole of Ponyville came at once: a hundred juicy cunts gushing, swelling, and growing pregnant from Rarity’s mere presence.
Fluttershy mewled in response, her belly pushing against the ceiling and lifting it straight off the top of the house. Although she would never admit it, the yellow pony was rubbing her dripping pussy against Rarity’s crotch, so eager she almost fainted.
“Oh dear,” Rarity said and broke out in a grin. “If that’s the game we’re playing.” She reached down to pull a thread and all of a sudden, her package came free. In the blink of an eye, her balls surged forward, looming above Ponyville with her cutie mark displayed above it at the size of Canterlot Castle itself. Her cock throbbed, growing constantly as it curled around the village, her first droplets of precum threatening to wash away the landscape entirely. Around the world, ponies dropped to their knees, cradling their expanding bellies—but none so much as in Ponyville, where the entire population already loomed above the ruined houses like so many multi-colored balloons.
Rarity graced them all with an imperious smile. Then she turned to Fluttershy, grasping her friend’s voluptuous hips. “Who am I to deny a friend in need? Hold still if you can, dear. This will take a minute.” She licked her lips. “Try not to pass out too quickly.”
