How Could It End Up Like This?

Spike took a deep breath as he slowly, slowly closed the door to the Castle of Friendship. He maneuvered it, making sure that nary a creek or a squeak escaped the door frame or hinges. He'd been careful to give them a little extra attention in his maintenance duties this week, oiling them up and testing for errant noises that might give him away on his secret mission. He let out a sigh as he closed the door and then turned on his heel, heading for the town proper. He'd been staying there with Starlight for a week while they were handling some local friendship problems. It'd been nice to visit with her. The move from Ponyville to Canterlot had been hectic last year, but he'd finally started feeling like things had reached an equilibrium. He still came and visited Ponyville, and he still saw all his friends. He took a trip every month to play Ogres & Oubliettes with Discord and Big Macintosh. All in all, things were working out wonderfully.

Which had, of course, led him to tonight.

He'd just turned eighteen, and with his wings growing in and even his body gaining a bit of height, he'd felt like maybe... just maybe... he'd have a chance resolving something he'd put aside for a very long time. But! He needed help. An edge. He needed to gather intelligence!

As long as Spike had known Rarity, he'd been head-over-tail in love with her. He'd never lost that feeling, and he'd gone through most of his young life with her present. Now that he was a bit older, it was time to confront her, and see if she'd give him a shot. That prospect was terrifying, and so he'd hatched a plan that he hoped would even his odds.

Rarity kept a diary. It lived up in her room—her boudoir, as she liked to call it—and was jealously guarded. He'd seen it once or twice, with a quill and inkwell nearby. She must have used it to record her thoughts, perhaps about fashion or other important things. While Spike felt like he knew Rarity pretty well, he wanted to do something really impressive. He wanted to really surprise her. And so, he'd come up with a plan.

As he walked through the sleepy streets of Ponyville, he clutched his satchel close. It held the key to his plan, after all, and he didn't want to drop it or spill anything. He sped up past the streetlamps, trying to stick to the shadows, just like the spies did in his Equestrian Esponyage Comics he'd used to read.

He finally made it across town to Carousel Boutique. The trip had, luckily, been uneventful. Looking up at the bright colors and stylish design of Rarity's first boutique brought him back to his childhood, and he allowed himself to smile as the nostalgia washed over him. He'd spent many weekends here, helping Rarity, fawning over her. His pulse quickened as he glanced around. Rarity would be gone still, out at some fancy party in Canterlot for the night, and so this was his chance. He walked around the corner to the backside of the building, glancing around to see if anypony had seen him. Not a soul graced his eyes, and he sighed in relief before looking up.

Above him was a window, cracked open just a fraction of an inch. He knew it stayed open like that during the warmer months, and he knew it couldn't open any further as a safety precaution. He took a deep breath. "Get in. Get to her diary. Find out the perfect gift to get her. Get out. You got this, Spike."

With that, Spike reached into his satchel and pulled out a potion bottle filled with purple liquid. He'd had Zecora help him brew it. He'd told her it was so he could do some cleaning in hard-to-reach spots in the library for Twilight. He didn't feel great about the lie, but it was hard to explain to ponies that he was sneaking into his friend's house to find out the perfect gift to get her so he could ask her out. Maybe a little morally wrong, but it was for a good cause! Right?

He took a swig of the potion, and smacked his lips. "Huh. Tastes like—woah!" Before he had a chance to finish, he began to shrink. Within moments, he was teeny tiny, standing below the window of Carousel Boutique. He flexed his wings and zipped up to the windowsill, and he marveled up at the edifice of the gigantic building. It was like flying up a cliff side! He sighed. "Just a little exercise. No... problem."

With that, he set off, flying into the boutique's lower floors. He zipped through the "inspiration room", taking in the valleys and hills of fabrics that filled the lowland spaces, while a variety of couture in half-finished states made up mighty mountains. His travels took him to the boutique's sales floor, a sprawling countryside of clothing racks and ready-to-wear like massive pine forests. He reached the stairs and had to pause at the base there to catch his breath and let his wings rest. The climb ahead was the last major hurdle. After this, it was easy: into Rarity's room, up to her bedside table, and then into her diary. From there, he could retrace his path, or even go out a higher window. Ascending was hard work, but descending was just falling in style, after all.

His strength gathered, he winged up the plateaus of the stairway. It felt like it took him a half hour just to reach the top, even though it was far faster, and once at the top he stopped to admire the view, sitting in the carpet like a tiny bug. This last hurdle conquered, he flew to the door to Rarity's room. It was open a crack, and Spike slipped inside. When he reached the sacred interior, this sanctum of femininity, he couldn't help but take in the sights and scents. It was... a bit messier than normal. Lacey garments and frilled dresses covered the floor, and the scent of vanilla and expensive perfume filled the air. Spike paused, taking in the room, and his vision danced with all the times he'd snuck up here, hoping to catch a peep of Rarity as she went about her day. There was a bit of a thrill to it, something that'd changed over time from curiosity to lust. He'd gotten his first feelings of drakehood while walking these halls, spotting frilly undergarments that smelled like his most desired mare. Spike chuckled and blushed at the memory and made for the bedside table... and encountered his first issue.

The drawer that the diary was in was closed.

Spike grimaced and moved in closer, getting a good look at the drawer. Not totally closed, but it was absolutely not ideal. He wriggled into the space between the drawer and the bedside table, pushing it with all of his minuscule strength. It budged a millimeter at a time, and Spike let out a huff. "Ho boah... this is gonna take a bit."

It was perhaps an hour later before Spike got the drawer open, and he grinned to himself, peering at the cover of the little black book. This was it! His moment of triumph! All this hard work was gonna pay off. He flew down and perched next to the cover, laid his claws on it, and... hesitated.

This was Rarity's diary. Her most secret inner thoughts. Her fears. Her... desires. Was he really going to peek in there, just to find out what kind of present might make him more likely to catch her attention? Spike grit his teeth, staring at the book, his heart pounding. This...

This was wrong. He slumped across the diary, letting out an exasperated huff. "What the heck am I doing? This was such a bad idea. I know Rarity really well. I should be more confident and just think up a present for her on my own."

As he flopped onto his back, he heard the distant bass sound of thunder. He sighed. "And it's raining. Nice timing, universe. Really driving the point home, huh?" It took Spike a few seconds too long to realize that it wasn't thunder that he was hearing: it was hoofsteps. His eyes widened in surprise. "... Oh crud. Rarity must be home!"

Frantically, Spike spread his wings and flew into the drawer, trying desperately to close it. The thunderous sound of hooves grew ever-louder, as well as a melodic voice that could only belong to one mare. "Oh no, oh crud..." Spike panted as he strained against the friction between the drawer and bedside table. It was no use! The door was opening, a delicate hoof stepping into the room, and Spike looked around, trying to find a place to hide.

No time. The bed! He zipped through the air and dove into the cushy purple velvet that covered his feet like shag carpet. Oh, these blankets had to be expensive! But, of course. Who else but Rarity would insist on the finest bedspread? He scrambled over hills and valleys, desperately trying to find a spot to dig in and hide. The hoofsteps grew louder, and above him suddenly loomed a white, fuzzy edifice. A mighty alabaster titan towered over him, clad in the finest of fashion-forward dresses, a lovely black affair with sparkling gems hidden within it. It filled the space before him like a view of the night sky. His eyes grew wide, and he stared up and beyond the dress, at Rarity's delicate neck and muzzle. She was grinning, and her blue eyes were focused elsewhere. He hadn't been seen! Great! Spike ducked down, lying prone, hoping that he wouldn't be noticed against the purple blanket, or maybe just overlooked as a piece of discarded fabric.

Her entire body turned above him, moving with such grace for such a massive creature, and Spike suddenly had a terrible realization. He was near the edge of the bed. A bed that Rarity had just returned to. A bed... that she was about to occupy. He stood up and started to run, grimacing, trying to adjust to find a place where he wouldn't get squashed.

Right ahead of him landed a massive avalanche of black fabric and sparkling gems. A dress! Rarity's dress! He drew to a halt and had to duck low as the displaced air from the garment pushed him back. He got to his feet and ran the other way, but a shadow fell over him. Spike froze, despite himself, and turned to face what was coming. A black-pantied, massive derriere, falling down upon him like the smiling moon from Marejora's Mask. The curl of a purple tail, like a cascading waterfall. A delicate dock, barely peeking from the top of the undergarment.

"So, this is how I die," Spike whispered to himself. He shrugged. "Eh. Coulda been worse."

WHUMPH.

Spike squeaked as he was compressed, buried by the soft white fur and generous muscle of the massive mare above him. He grit his teeth and held his breath, trying not to suffocate as the avalanche of mare flesh and silken panties surrounded him. He couldn't move! It was pitch black, and he was trapped, fully surrounded by gloriously soft fur. He squirmed ever-so-slightly, trying to see if there was any escape from his predicament... and when he wiggled his tail, he discovered some movement was possible. Desperately, he squirmed south, following along the small indentation in the ass surrounding him that his tail had luckily landed in. His darkvision-capable eyes adjusted rapidly, bringing his vision into relief. All he could see was white fur and black undergarment, which was not helpful. He pushed, muscles straining, chest burning as he held his breath. He finally broke through, air surrounding him, and he gasped in a grateful lungful. His nostrils were immediately filled with the cloying, warm scent of mare. It was feminine, tangy, and filled his entire being with the smell of vanilla and expensive perfume, combined with more musky scents that wafted from overhead.

Spike blushed, still supine beneath Rarity, and reached up. There was just enough room to lift his claws a little ways up, and they almost immediately encountered... silk. Soft, hot silk. The blackness wasn't just the absence of light: he was surrounded by undergarment.

Spike could barely hear Rarity let out a sigh, more feeling it as it reverberated through him, and she said something. Unfortunately, all that carried was her dulcet tones, but it was incomprehensible. He was, after all, buried beneath her ass. Spike grimaced as the walls around him shifted as Rarity moved about, and he had to scramble to move with the motion and keep himself from being compressed again. He barely managed, his head and tail alternately being slightly squashed. Luckily, his scales were hard enough and Rarity's ass and her bedspread were soft enough that no serious damage was done... though Spike was sure he'd need to fix a few bent spines along his head at this rate. She finally settled again, leaving Spike pressed between the two glorious globes of her butt cheeks.

"Oh buck..." Spike breathed out after a moment, and he shifted slightly. His nose pressed into the undergarment above him unintentionally, and he paused there. He blushed, and gave in to a carnal request, and he took a whiff. Rarity smelled amazing, right here, and Spike found himself nuzzling a little bit at the fabric, stroking along the silk with his claws, while he inhaled her tangy, vanilla scent. He froze as his body began to react to the feminine scents surrounding him. He glanced down at his crotch, grimacing at the traitor between his legs. "... Seriously?"

His cock didn't care that they were probably about to get suffocated between a mare's ass cheeks. It just knew that it was right where it wanted to be: between a mare's ass cheeks. Spike suppressed a shiver that ran up his spine, and he leaned back, trying to relax. "Deep breaths. It'll be okay."

Deep breaths were the opposite of the remedy, though, as each inhale took in the scent of mare. His cock was rock-hard, the throbbing head pressed gently into the silk of the undergarment a mere inch from his face. Spike bit his lip. "... Dang it."

Suddenly, Rarity shifted again, squirming, and Spike found himself pressed into the bed, his tiny crevice of air squashed as something happened above him. He grimaced, holding his breath, pressing himself down as small as he could, hoping that Rarity shifted her position. She did, and for a brief moment, light entered his space as her back arched, and cool air flowed in. Spike took a deep breath, almost ready to dash for an escape, but just as quickly as she'd moved one way, she shifted again. The black garment overhead slid away, flowing like a massive tablecloth being pulled from beneath a set table. Spike had to grab his erection and push it down to stop it from getting caught in the garment. Finally, the movement stopped, and equilibrium resumed... but things around Spike had massively changed. There was no more black undergarment above him. Now it was naked fur... and beyond that, puffy pink lips that spread above and around him.

Spike hadn't been certain before... but now he was quite sure where he was located, and his blush intensified, as did his erection. He stared up into Rarity's pussy lips, taking them in with shaky breaths. Her hips shifted slightly, and her body settled... and Spike suddenly was pressed against her. Wholly trapped. His face pressed into her sex, his entire body positioned along the warm crevice, his erection actually piercing her ever-so-slightly. He gasped, trying to breathe, and pushed his hands up. Rather than pushing away, they pulled her lips aside, just enough that Spike could get a breath.

And what a breath it was. It was pure Rarity. The vanilla and perfume were gone, replaced with more primal scents, and the warmth filled him and made his head spin. He giggled to himself, and without thinking, he pushed his hips up. His cock speared into Rarity, just a minuscule pressure, but to Spike it was heavenly. Soft lips sliding around his cock, caressing him, covering him and the whole of his being. It was divine, even if it was getting hotter and harder to breathe. He took another breath, the cloying scents overpowering him, activating some more ancient part of his brain. He thrust a little more earnestly, panting, and even pressed his hands up into Rarity's pussy, spreading her sex open and reaching up, feeling her from the inside with his entire body. In his ecstasy, his brain hummed as he felt his cock throb and his breathing became more ragged, his thrusting more hurried. He could barely believe what was happening, but... here he was. He'd come here to find a gift for Rarity, and the mare had ended up giving him a gift he'd never be able to repay... mostly because explaining it would be very difficult.

He gasped, panting, as something squeaked thunderously above him, and everything shifted. He was... stuck! Caught on her, inside her folds, deeper in her than he'd ever imagined. He'd fantasized often about being balls deep in Rarity, but this? Ho boah.

He moved with Rarity as she squirmed, and her voice rumbled out something, and suddenly he felt a new pressure enfolding him as Rarity ass cheeks shifted to a new position, and he found himself pulled deeper into Rarity's hot pussy. He growled in hunger, thrusting his hips, burying himself inside her further, until he felt something catch on his tail. A mighty weight brushed by, catching Spike's tail tip, and pulled him away from the heaven he'd been entombed in.

His cock throbbed, spurting, and Spike groaned in pleasure as he was brushed free from Rarity's pussy lips, leaving a tiny trail of sticky white behind, staining one beautiful red pussy lip. Deliriously, he hoped that Rarity would appreciate his little 'gift'. He fell a good distance to the floor, bouncing on the soft carpet, and Rarity's voice became suddenly clear. "What in Equestria was that?! Oh, Celestia, I hope it's not velvet mites again! I told Sweetie Belle no more Entomology experiments in my boutique. I don't care who she's helping get what cutie mark!"

Spike lay still, panting, his cock slowly retreating, and his blurry vision cleared slowly. He rolled to his feet with a little grunt, his muscles protesting, and he retreated underneath the nearest undergarment to recuperate. After a moment, he sat up, face flushed. Oh gosh... he'd... he'd just...

He decided not to think about it. Not right now. Right now was the time for escaping, and living to somehow find a way to make it up to Rarity that he'd nearly read her personal diary... and then had accidentally ended up fucking her.

"... There's literally no explaining this." So Spike got up, spread his wings, and flew for the nearest window. He paused on the sill and turned, staring across the expanse of the room to where Rarity lay, grumbling about her sister. "... I promise, though, I'll find a way, and hopefully you'll—"

And then the potion's power ran out, and Spike exploded into his normal size, shattering the window. Rarity screamed. Spike perched awkwardly on the remains of shattered glass, and he smiled a deeply embarrassed smile at Rarity. "Ho boah."
