“Woo!” Spike jumped out of bed, covers tossed with abandon as he ran to the far side of his room. With a red marker, he crossed out today’s date, the thought of all the tasty gifts he might receive floating across his tongue. Quickly, he dressed and, with a wink at himself in the mirror, trotted out into the castle proper.

“Twilight! Guess what day it is!” When his echo was met with no response, he frowned, searching for the Princess of Book’s favorite nooks. Her bedroom, the library, and even the map room turned out to be completely Sparkle free. Finally, he found a letter taped to the inside of the Castle doors. After reading, Spike raised an eyebrow. “Really? On my Birthday?

“Of all the days to go teaching in Canterlot…” Spike groaned, crumpling the note in his claws. Then he sat back, closing his eyes. “Oh, I’m going to give it to her good when she gets back.”

Kicking the castle doors open with more force than necessary, he took a step back when he saw somepony waiting on the other side. In a lovely sunflower dress, Sweetie Belle looked at him with her head cocked to the side. “You’re gonna give it to who ‘good’? Do I need to punish the bad dragon again?”

With a little cough into his claw, he smirked and crossed the threshold to hug his special somepony. They separated with a little peck on the cheek before Spike was able to answer her joking question.

“It would be torture if you didn’t punish me, Sweetie.” He pulled her snug against his chest, her small frame and bosom fitting nicely against him. “Seemed like the princess of responsibilities and friendship forgot about her number one assistant.”

Sweetie nodded, a cute smile on her lips. “Well, I’m sure she’ll remember… eventually. Somewhere between her schedule, and her lists, and her everything else…”

They kissed again, then shared a little laugh at Twilight’s expense. As the morning sun illuminated and fractured off the crystal castle, Sweetie lit her horn and extracted a small bound book from her mane. Advanced Transmutation and Transfiguration for the Delinquent Mind came into view, and Spike couldn’t help but whistle.

“I finished it, Spike!” Her smile was huge, and carried a little mischievous accent in the corner of her lip. “And I’m totally ready to give you your present.” She floated it over to him, and as his claws closed on it, she sauntered ever closer. As her tail wrapped around his waist; her hot breath tickled his ear. “Anypony you want.”

Spike almost dropped the book. Almost. “Anypony?” Her fur tickled his chin as his eyes rolled to the top of his head, his mind spinning a huge wheel of images of ponies. “Even…” A particular figure and ivory colour came to mind.

“Yes, even her.” Sweetie blew hot air out of her nose as she turned her head back towards town. “I know I’m a late bloomer, so I’ll do whatever it takes, Spike.” She bit her lip. “I really want to make this birthday special.”

Spike took a deep breath, a genuine smile crossing his face as he looked deep into Sweetie’s emerald eyes. “Just you being here makes this special.”

Sweetie snorted, her horn scraping against Spike’s scales as her head jerked. “I hope you’ve got some meat to go with that corn, Spikey.” She bit her lip as she turned, and together, they headed towards Carousel Boutique.

A gentle chime announced Sweetie and Spikes arrival to the boutique, nary a customer in sight at such an hour. There was a recognizable drumming of water, followed by the humming of perfection.

“I borrowed the key this morning.” Sweetie giggled as they proceeded past the gorgeous dresses and occasion suits. She pulled Spike along with her, hand in claw, until they got to Sweetie’s bedroom.

“Yeah, the boutique isn’t usually open for another hour or so…” Spike made himself comfy in the pink and white pillow-ridden abode. With a flop onto the bed, he watched as Sweetie wiggled in anticipation. “I used to wait outside just so that I could ask to help her with work.”

“Aw… Poor Spikey Wikey has a little crush on my sister.” She stepped up, pushing herself between his legs that hung off the end of the bed. “She’s just too hot for her own good.” Sweetie frowned at nopony in particular. “You’d think she’d stop stringing you along…”

“I didn’t even tell her that we were a thing for like, half a year…” Spike rubbed his scales with his claws; the scraping noise made Sweetie cringe back. “Sorry.”

Sweetie accepted his apology by tracing her way up his stomach with her fingers as she slowly bent over, grinding firmly between his legs. “She’ll be done soon, it’s been about an hour.” She couldn’t help but give a little roll of her eyes. “Always uses up all the hot water... “ Her magic had already pulled the book back into view. “You’ve read it, Spike. Which spell first? We’ve got all day to have fun.”

Spike licked his lips once. Twice. A third time. “Number four, I guess. That seems like a good one to test.”

Sweetie tapped the book against his chest. “You’re a naughty dragon, Spike. And I...” She purred as she leaned over him. “...love every bit of it.”

The angelic humming grew louder as the water cut off, the fast flick of the curtains preceding the trickle of water upon the tile floor. Spike and Sweetie Belle stood frozen as they listened to Rarity musically towel off her hair, the anticipation nearly suffocating in her room.

Eventually, after at least ten minutes had passed with Sweetie and Spike locked eye-to-eye, the bathroom door opened. Steps clopped down the hall past them, and they finally let out the breath they’d been holding.

“Any reason we’re being so quiet?” Spike raised an eyebrow. Sweetie gave a shrug before dragging herself off Spike, a lingering palm across his hot crotch.

“Because it’s fun?” she cooed as she led him to the door. “I know you want to watch, Spike. I know I want you to.”

“Oh, Celestia, yes.” Spike stepped up to the door as Sweetie Belle opened it. Sweetie stepped slowly through it, turned to Spike, and winked at him.

“Happy Birthday, big boy.”

The hem of her sunflower dress spun as she turned into the hallway, heading towards the kitchen where Rarity had gone. Spike followed at a distance, keeping out of sight as best he could.

“Rarity~” Sweetie skipped down the hall in the most disarming, carefree motion. “Rarity? Guess what day it is!”

“Oh, Sweetie Belle? You’re up early.” The sound of pouring cereal made Spike inch closer to hear better. “School doesn’t start for another week, so it can’t be that…”

“It’s Spike’s birthday, Rarity…” Sweetie whined, stomping a hoof. “I can’t believe you forgot.”

There was a sigh, then the setting of a glass on wood. “Sweetie, I’ve been busy. The shop in Canterlot, and the friendship missions and…”

Sweetie cut her off. “He’s been helping you almost everyday since he moved here. How could you forget?”

Spike could feel the pout on her lip from where he stood against the wall adjacent to the kitchen. He peeked around the corner to glimpse Rarity standing across from Sweetie Belle, hands on her hips, still wearing her royal blue shower robe. She hadn’t tied it quite tight enough, and her massive chest was already cresting the mountain peak. Her hair, still damp, was slicked across her right shoulder, just perfectly accenting every visible curve.

“I don’t have time today, Sweetie.” Rarity took a deep breath. “But if I move things around, maybe I’ll at least be able to swing by and give the little darling a gem and a hug.”

Spike grumbled under his breath, and Sweetie’s eyes flicked to him for only a moment. Finally, Sweetie stepped around the breakfast table separating them and lit her horn.

“It’s Spike’s birthday, and what my Spikey Wikey wants, my Spikey Wikey gets.” In a flash of brilliant emerald magic, Sweetie Belle launched herself at Rarity. The surprised fashionista cried out, her limbs flailing out as Sweetie connected with her stomach, horn first. Then, in a wiggle of flesh and magic, melded into her.

Rarity’s eyes widened in panic as Spike’s jaw dropped in awe. He watched, biting his lip as little ripples of fur ran up and down Rarity’s gorgeous body, Rarity herself in complete shock.

“Sweetie! Where did you… What did you do!?” She started to shake, then things started to change. Her mane tinted with lighter shades, and streaked with a single white line. Her tail twisted into a roll akin to a frosted breakfast pastry. And finally, her face scrunched slightly and took on a visage more similar to her sister. “Ah!” was the last thing that escaped Rarity’s mouth before her limbs fell limp.

Then she raised her head, a sure smile adorning her face. “Oh, Spike. Your filly friend has a little…” She looked down at her loose robes, into the mountain crevice; her smile widened further. “...Your filly friend has a big surprise for you.”

Spike stepped out from his corner. “Sweetie Belle?” He stepped towards Rarity with an open mouth and wide eyes. “Did it work?”

Sweetie was exploring her new self, hands caressing every curve before finally landing on her sister’s massive breasts. A long moan escaped her, and her eyes closed from the sensation. “You know…” she said as she lifted them, each one the size and weight of a large melon, “...I get why you’ve liked her for so long.” She stepped up to Spike, his head just getting wedged between her chest.

“You’re technically an adult now, Spikey. So how ‘bout we celebrate?” She pressed his head between her breasts before pulling him along to Rarity’s bedroom. The elegant purple drapes were fortunately already closed as Spike was first led, then pushed onto the bed.

Sweetie teased the already loose robes, her breasts baying at the clothes like hound dogs trying to get free. When she finally dropped the robe, and her body was fully exposed, Spike grunted hard as he nearly climaxed on the spot.

“Oh, no, not yet,” Sweetie cooed, bringing Rarity’s porcelain white fur up the full length of Spike’s already boiling body. She brushed against his member, and Spike had to bite down on his lip to not squirm beneath the beauty upon him. “Tonight,” she said, Rarity’s breasts pressed hard against his chest, “she’s going to repay you for every kindness. I’m going to make sure of that.”

Spike drew in a shaky breath as Sweetie bent down, her magenta mane swirling to caress her face. Her wet, glistening mouth opened as she took him fully. She angled her neck, and her throat was opened wide as Spike’s world became only pleasure. His claws clamped on the downy mattress, his eyes closed as he tried not to trust upwards.

Again, and again, and again, she swallowed his dick fully, her tongue tickling and teasing him as she watched his progress towards his peak. With a sultry and devilish grin, she’d move off with a little pop, and Spike would stick out his lip. Then again, Sweetie used her sister’s body to fulfill Spike’s long awaited desires.

It was only when he was sore from being denied repeatedly that she finally moved away, and started to turn to offer her magnificent posterior to him. Then, her whole body shook. Spike stopped just as he had moved to mount her, eyes wide and concerned.

“Sweetie Belle?

She shook like marshmallow in a mixing bowl, her fur ripping as a strained cry emitted from her clenched mouth. “Get… Out!!” Muscled tensed, Rarity’s horn glowed two different shades of green before her form blurred. With yell and a thunk, Sweetie fell down onto the floor, both of the sisters sweating and wide-eyed.

Rarity looked from Spike, to Sweetie, and back again, shivering with a mix of rage, confusion, and something else unidentifiable. Her mouth opened to speak, her hand in the air with a glower on her face, but then she stopped. She coughed, twice.

“Sweetie, we will not discuss this later. Not ever. Spike…” The poor dragon had long since gone soft, and had scooted as far from the angry fashionista as possible. “Happy birthday.”

The pair were promptly defenestrated without ceremony, the shuttered slamming shut behind them.

Spike picked Sweetie up and brushed the dirt from her coat. “I’m sorry I asked you to-”

“Are you kidding!? That was the most fun I’ve had in ages!” Her smile was bright as the morning sun above them. “And you know what?” She gave Spike a mischievous grin. “She had fun too. Otherwise, we’d probably be skinned alive and used as fabric by now. She’s just… too much of a lady to admit it.”

Spike raised an eyebrow. “So what? You’re not getting grounded?”

Sweetie rolled her eyes. “Oh, I’m sure she’ll find some form of revenge. A proper lady always does.” She moved to grab his arm, cuddling up as he pulled her close in return. “Soooo, now what?”

Spike tapped his chin with a claw. “Cutie Mark Crusaders, magical kinky adventures?” She answered him with a kiss on the cheek. “I bet we’ll get up to all sorts of trouble… as long as you don’t chicken out.”

“Are you kidding? I have a feeling I’ll remember today forever. You know what, let’s make a whole week of it. At least, until Twilight shows up to ruin the fun.”

From the window of the boutique, a flustered unicorn narrowed her eyebrows at the pair. Her body was sweaty and still dripping with her own sex, and she couldn’t help but stick out her lower lip as they left. “No, Rarity. A proper lady does not get jealous of her sister. Well, she doesn’t admit to it anyway.”

She watched the pair trot off to inevitably cause more trouble. “I should probably tell Twilight…” She bit her lip, hesitating as she faced her bedroom door. “...later. I’ll tell her later. After I get the juicy details from my sister, of course.
