Sweetie’s Reward

Rarity leaned against the kitchen counter, sipping the last of her tea as Sweetie cleared the dishes. The meal had been delightful, and Sweetie’s cooking had truly surprised her so much so that Rarity couldn’t help but smile to herself every time she remembered how far her sister had come.

As Sweetie turned from the sink and dried her hands, Rarity stepped forward, brushing a lock of damp hair behind her sister’s ear.

“You’ve truly outdone yourself today, Sweetie,” she said softly. “With everything you’ve done and how well you’ve taken to our little magical experiments I think you deserve something special.”

Sweetie blinked, surprised. “A reward?”

Rarity nodded. “Yes. I want you to choose something anything. Name a change, and I’ll fulfill it. No questions asked.”

Sweetie’s cheeks flushed. “Anything?”

“Anything your heart desires.”

Sweetie looked like she might burst with excitement, but Rarity held up a finger.

“Take a moment to think it over. I want you to be sure. I’ll be waiting for you upstairs.”

With that, she turned and ascended the staircase with practiced grace, her silk robe trailing behind her.

Sweetie watched her go, heart pounding with anticipation.

-———

Rarity sat patiently in her bedroom, bathed in warm lamplight and soft shadows. She had changed into a sheer silk robe that hugged her curves just so, the fabric cinched delicately at her waist. Her heart fluttered not with nerves, but with anticipation.

After all their teasing, after meals and shared touches and whispered affections, tonight would be Sweetie’s reward.

The door creaked open.

Sweetie Belle stepped inside, her cheeks already flushed. She had changed as well into a pale pink camisole that clung to her curves like it had been painted on, and a pair of light gray shorts that rode high on her thighs, clearly a size too small. Her breasts pushed tightly against the thin fabric of her top, nipples visibly poking through. The hem barely reached her navel. Her shorts looked like one wrong movement might snap a seam.

She smiled, bashful and excited. “I’ve decided.”

Rarity sat up a little straighter, gesturing for her to come in. “And what did my precious sister decide?”

But before Sweetie could speak, Rarity lifted her hand gently.

“First things first. There are some... clarifications I need to make.”

Sweetie tilted her head, curious.

Rarity turned slightly and addressed the Root, her voice calm and commanding.

“Will Sweetie Belle remember any changes I make to her from now on *unless I specify otherwise*?”

A warm shimmer rippled through the air.

“And will any physical transformation I cause in those aware of the change be experienced as pleasurable by the one undergoing it?”

Another shimmer. Another yes.

Sweetie gasped, shifting on her feet as her thighs pressed together instinctively. Her already-tight camisole seemed even more confining.

“You mean I’ll... feel everything?”

Rarity’s voice dropped to a purr. “Yes, darling. Every glorious inch.”

Sweetie inhaled sharply, stepping closer. “Then... I know what I want.”

She leaned down and whispered her request into Rarity’s ear. Whatever she said made Rarity blink in surprise, then grin with delight.

“You really are full of surprises tonight.”

She stood, brushing Sweetie’s hair back from her face. “Very well.”

Rarity raised her voice again.

“Has Sweetie Belle always had the body and presence she’s dreaming of right now?”

The answer was yes.

And this time, Sweetie knew it.

The change was slow and overwhelming.

A rush of warmth surged up her spine, blooming behind her breastbone, radiating out like molten magic. Her breath caught in her throat.

“Oh—oh Rarity!”

The camisole clung to her chest for a moment longer... and then it gave way. Her breasts surged forward, swelling against the fabric until the seams creaked. Her nipples pressed tighter, then burst free as the top split down the center. Her moan was long and loud, filled with shock and pleasure.

Rarity gasped, eyes wide with admiration and arousal.

Sweetie’s legs stretched, her hips widened. Her ass rounded and filled her shorts to bursting. The waistband groaned audibly, the button popping off with a sharp *ping* as her thickening thighs split the seams. She stumbled slightly, gripping Rarity for balance as her body continued its blissful ascent.

Her moans deepened into ragged gasps. Her skin glowed. Her hair lengthened. Her lips parted in a trembling smile as pleasure rippled through her, driven by every inch of growth.

At the same time, Rarity let out a quiet whimper.

Her own robe tightened. Her breasts, responding to the earlier truth, expanded gently just enough to remain the largest in Ponyville. A delightful heat rushed to her nipples, and she squeezed her thighs together as the magic teased her own senses.

Sweetie collapsed to her knees, panting, as the final waves washed over her. Her curves now rivaled the most decadent fantasies. Tall, busty, radiant.

A goddess made flesh.

And she remembered every second of it.

Rarity knelt beside her, brushing sweat-slick hair from her sister’s flushed face.

“How do you feel?”

Sweetie’s lips curled into a needy smile. “I feel like I’m ready to be yours forever.”

Sweetie Belle knelt before Rarity, still glowing with the heat of transformation. Her skin shimmered with sweat, her breath came in trembling waves, and her ruined clothes clung to the last threads of their seams. But it wasn’t until Rarity placed her hand gently under Sweetie’s chin and said, “Darling… stand up for me,” that the full impact of her new body became clear.

Sweetie stood.

And stood.

And kept standing.

Rarity slowly tilted her head back, eyes widening with each inch. Sweetie now towered over her a full head taller. Her thighs were thicker than Rarity’s waist. Her hips flared like an hourglass. Her breasts hung heavy and full, proud and high, casting deep shadows as they swayed with every movement.

Rarity let out a soft, unbidden gasp.

Sweetie noticed. She smiled.

Without a word, she lifted her arms and gave her sister a slow, sensual spin. Her hips rolled with confidence. Her breasts bounced with each pivot. She paused halfway, giving her rear a teasing sway before turning to face Rarity again, arms at her sides like a goddess on display.

“Well?” she asked breathily. “Do you like what you see?”

Rarity nodded, speechless.

Sweetie stepped forward, her presence immense but gentle. With ease, she slipped one arm under Rarity’s back, the other beneath her knees, and lifted her off the floor in a single smooth motion.

Rarity squeaked. “S-Sweetie!”

“Hush,” Sweetie whispered, nuzzling her sister’s cheek. “Let me carry you.”

She walked them both to the bed and gently laid Rarity down against the pillows. Then she climbed atop the mattress and positioned herself above her sister knees straddling her thighs, arms extended on either side, her powerful body hovering just inches above.

Their breasts pressed together, pillowy and soft, nipples brushing and drawing twin moans from their lips. Sweetie’s face hovered over Rarity’s, her hair falling around them like a curtain.

“I want to thank you,” she whispered. “Properly.”

Before Rarity could answer, Sweetie leaned down and kissed her deep and needy, with more **** than before. Rarity responded with a moan, hips shifting beneath her, legs wrapping around Sweetie’s waist.

“You’re quite forward tonight,” Rarity panted between kisses.

“I want to make you feel good,” Sweetie whispered. “I want to show you how grateful I am.”

She kissed down Rarity’s throat, trailing her tongue along the collarbone, her fingers working open Rarity’s robe to reveal her breasts. With reverence and hunger, Sweetie took one into her mouth, sucking gently, her hand teasing the other.

Rarity writhed beneath her, gasping as pleasure rolled through her.

Sweetie worshipped her slowly—licking, kissing, stroking every curve. Her hands traced over Rarity’s hips, down her thighs, then slid back up, lifting the robe higher.

“Let me taste you,” she whispered, her voice husky and reverent.

Rarity nodded, breathless.

Sweetie kissed her way down, each touch a promise, until she nestled between her sister’s legs. She began slowly tongue flicking, lips pressing, fingers spreading her open to taste the heat and sweetness she craved.

Rarity cried out, gripping the sheets.

Sweetie’s tongue moved with skill and purpose, stroking her sister to peaks of pleasure over and over. Every gasp made her smile. Every moan made her hungrier.

When Rarity came, it was with a sob of bliss her legs trembling, back arching, mouth open wide.

Sweetie licked her clean, then crawled back up to lie beside her, cradling her in strong arms.

“You’re everything to me,” she whispered. “And I want to be everything to you.”

Rarity curled against her, kissed her chest, and smiled.
