Mountain Climbingby Unideal
Chapters
The Mountaineer
Twilight Sparkle was bored. And frustrated. And third emotion conveying dissatisfaction. Her quality of life had entered into a downward spiral, and while she could point to any number of problems behind that trend, a good chunk of it was a good old-fashioned inability to hit orgasm.
It wasn’t for lack of trying — she had more toys now than she knew what to do with — so much as it was the lack of imagination. She needed to fantasize! Something to get her primed and ready. The time had long passed when she could masturbate to a cheap smut rag. She’d read every saucy novel in the library now. The dominating escapades of Mistress Topspin and poor Bottom Line, hot as they were, simply didn’t cut it anymore. Perils of a photographic memory.
“Uuuuuugh.” She rolled herself up in her sheets, trying to smother her own burning need. She brushed a couple fingers over her soaking panties, trying to let off a little heat, but that only served to stoke the flames. “I know life’s a ride, but I wanna get off now.”
A crash rang out from downstairs and her mind flickered to Spike. “Ugh, no!” she grumbled into her pillow. Not Spike. He’d grown a lot as of late, and was most certainly an eligible bachelor, but she couldn’t even look at him right now. He’d gotten all sorts of obnoxious and rebellious after reaching eighteen. Never doing chores, eying all the female visitors, and even folding pages in books! Sexually frustrated as she was, Spike was causing her too much regular frustration to even consider.
Another crash downstairs. She looked up from her pillow. “Speaking of Spike...” What exactly was he doing down there? Time to go check on him. She magicked the blanket off her and shuffled grumpily toward the door. So help her, if Spike was doing anything destructive down there, she’d find herself with plenty of dragonskin for her potions.
Wait. Her eyes snapped open. “The potions!” She shot down the stairs as fast as her feet would take her, wings fluttering anxiously behind her back. “No, no, no — oh, nooooo.” She crumpled to her knees when she saw the mess. Spike had gotten into the potions. Beakers lay broken on the desks, the shards dripping with beyond-precious contents. Her research manual had a hole burnt in it and her notes were soaked beyond belief.
Then sorrow turned to outrage. “As soon as I get my hands on the dragon, I’ll...” She looked around. “Where is that dragon?” There seemed to be no sign of him in the foyer, and she hadn’t heard the door open, so he had to be in the room. Where, though? It wasn’t exactly easy to hide six feet of scaly purple lizard. She should have seen him by now...
Her ears twitched as they caught a skritch-skritch-skritching sound. Just by her feet, beneath the desk. She groaned. Mice in the library? That was all she needed now. She bent down to check for any scurrying vermin, and found... “Well, what do you know?” she said, a grin spreading slowly over her face. “Scurrying vermin.”
“Twilight!” Spike squeaked. “Thank goodness you found me!”
“Thank goodness indeed,” she murmured, scooping the tiny dragon up. “Looks like you drank my shrinking potion.”
“I didn’t know!” He shouted, standing up in her hand. He was roughly the height of her palm now, which made him the perfect height for punishing. Six-foot-tall Spike never seemed to hear when she lectured him, but maybe six-inch-tall Spike would listen a little better. “I was thirsty and thought you were making a new flavor of Colta Cola.”
Twilight narrowed her eyes. “After I told you not to touch any of the potions on that desk.”
“Well, I might’ve tuned you out. Didn’t think it was that important.” He shrugged his little shoulders, then looked down at himself. “Did you mention anything about how long the potion lasts? I think I was an inch taller a minute ago.”
“It might be an interaction effect with the other potions you knocked over,” Twilight said through gritted teeth. She was just about ready to squeeze him and shout him into a pulp for what he’d done. But then a bright spark lit a bulb in her brain, and she got an awful, evil, incredible idea for teaching Spike a lesson. She grinned her nastiest grin. “I think you’ll be getting smaller for a while yet, Spike, so we should get on your punishment quickly.”
“Aw, but Twilight, I didn’t—”
“No buts,” she told him, magicking away the clutter on her desk. Every last beaker-shard and puddle of potion. Her research was beyond saving, but the desk could still be useful. Very useful. She set him down on the surface and pulled her shirt over her head. “I’m going to be honest with you, Spike, I’ve been feeling pretty needy today. I’m sure you’ve been listening to me whenever I talk about how important efficiency is, so we’re going to kill two birds with one stone.
“W-which two birds?” Spike stuttered, shuffling back as she unclasped her bra, and practically scrambling as she set her breasts on the cool wooden surface. “Those two birds?”
“Maybe,” Twilight giggled. She’d never admit it to anyone, but she was more than a little proud of her assets. They’d always been big (and sensitive!) for a mare her size, and had only gotten bigger after her ascension to alicornhood — firm and full mounds that sat a teensy bit over a handful. Sure, the extra back pain was terrible, but she had spells to handle that. The stares, though, were priceless.
And Spike’s staring was beyond priceless. He gaped and gawked at her bare naked chest, pressed just slightly into the desk. Slowly he mustered the courage to approach it, and she couldn’t help but notice that he stood just chest-height to her swollen nipples. He was definitely getting smaller. So tiny that she could practically do anything with him. She bit her lip to stifle a moan as her mind raced over the possibilities.
She’d finally found her fantasy.
“We’re going to play a game,” she told him, giving her chest a little pat. She slipped a hand down toward her sopping panties — not like Spike could see what was going on beneath the desk. “I’m going to drop you under one of my, ah... my breasts, and you’ll have to get out in under five minutes. If you win, I’ll forgive you for messing with my potions, and I’ll work on something that can grow you back ASAP.”
“Uh...” Spike took a second to keep staring, the blush evident on his cheeks and between his legs. He seemed entranced, or maybe intimidated, by a nipple the size of his head. “And if I lose?”
“Then we’ll, um, play another game,” said Twilight. She flushed as her fingers worked her up from down below. Luckily for her that Spike wasn’t staring at her face. “And we’ll play until you win. Sound fair?”
“I guess so,” he said. Then a glint sparked in his eye and a cheeky grin spread over his face. “Wait, no. I think you need to sweeten the pot. He gestured toward her tall-as-him tits. “It’s only fair, right? The odds are kinda stacked against me. So how about this: If I win, you also have to do whatever I say for the rest of the week. Like doing all of my chores for me, promising to stop nagging, and calling me Lord Amazing Spike.”
“Fine,” Twilight grumbled. If ever she’d had a doubt about what she was putting Spike through, those had all evaporated. It was clear now that Spike needed to be taught some manners. “We have a deal?”
“Deal.” Spike grinned harder. “Prepare to call me Lord Amazing Spike.”
Twilight snorted. “As if!” She lifted up a ponderous tit, brushing a finger slowly over her nipple. Dear Celestia that felt good. She could only imagine how electric it’d be with Spike trapped under there. He wasn’t getting out from that. She’d make sure of it.
Spike strutted confidently under her shadow. “You ready to lose?” came his squeaky voice.
“Pretty sure I'm ready!” She laughed and let go of her breast, and a veritable wave of flesh fell on her little dragon. “Are you?”
The Mountain
Spike had read a story once about a giant dragon who’d carried the whole world on his back. He’d thought it was just a neat story back then, and he could care even less about fairy tales at his age, but it occurred to him now just how that dragon must have felt. Twilight’s one breast felt like the whole sky falling on him; a wave of warm, unrelenting fat. It wasn’t enough to floor him by a long shot, but darned if it wasn’t the heaviest thing he’d ever carried.
“Dragon strength, don’t fail me now.” He’d fallen to a knee at first, but as soon as he put his back into it, he could feel Twilight’s squishy tit moving up. “Ha!” He knew it. She was big, but not too big yet to crush him. All he had to do was start moving and he’d win the game easy.
“Hanging... hanging in there, Spike?” came Twilight’s voice from above. She sounded a little off. Was she...? No! He shook his head, trying to clear his thoughts. He had to focus! Twilight was probably just nervous that he was going to win.
“Gonna make you clean the bathroom!” he called, taking a solid step forward. Good progress. If he just kept his shoulders up and his feet moving, he’d be out from under here in no time. A good thing, too. The air under Twilight’s breast was only getting hotter and heavier from her own, all-encompassing body heat. “Ugh.” Mammals and their awful warm blood. “And the toilet too!” he groaned.
“Sure about that?” Twilight giggled, her chest bouncing softly on top of him. “Because aaaany second now...”
“Oh no...” Twilight’s breast, already the heaviest thing he’d carried on his back, was getting even heavier. He was still shrinking! The gap of light that represented freedom closed slowly as he shrank toward the ground. The weight of the world on his shoulders grew from ridiculous to impossible, and slowly he fell again to his knees.
“You can always give up, Spike,” Twilight sang. “I’ve got so many... mm... ideas for new games after this one.”
“Never!” he shouted. But it was an empty bluff, and they both knew it. The avalanche of Twilight pressing down on him was more than he could take. Eventually his legs gave out, and Twilight’s warm breast pressed him into the desk. It didn’t crush him to death, like he’d worried it would — it was more of a big, absurdly heavy pillow than anything — but he was definitely at risk of smothering. It was pitch-black now, and the atmosphere had become a full-on sauna, with Twilight’s own sweat covering his body in a slippery coating.
He tried scratching at her like an angry cat, but that only seemed to spur Twilight on. “Keep... keep going, Spike!” she told him, her voice dulled by a thick layer of breast fat, and followed up by a muffled moan. “You can still... ah... you can still... mmmf...”
That bitch! She was getting off to this! “Twi—!” he tried shouting up to her, but there was no room to do that without a mouthful of salty breast sweat. Plan B, then. He clawed himself forward, finding a little purchase on the slippery surface of her boob, and slid up. If he could just keep going before time ran out, he could—
“If I’m right,” came Twilight’s muffled voice again. “It should happen right aboouuut...”
Oh no. Spike’s claws slid off her skin as he shrank again, and her breast caked him into the desk. “Alright, alright!” he shouted up to her, using all four of his limbs to push up as much slippery tit as he could. “I give up! You win, Twilight!”
The only answer he got back was another moan, and the world around him shook in response. She couldn’t even hear him! With no way out and no hope left, Spike took a deep breath of what thick, boiling-hot air remained around him, He let Twilight’s breast swallow him altogether, and focused on conserving oxygen.
“Time’s up!” came a booming voice from above. The voice giggled. “Looks like you’ve stopped shrinking. You got pretty tiny, didn’t you, Spike?”
Spike’s eyes snapped open. Light! Precious light! He inhaled. Air! Sweet, cool, delicious air! He was safe! He was free! He was... Hold on. He turned around to see a positively gigantic Twilight standing over him. He was screwed.
“You lost,” said Twilight, grinning down at him. A predatory glint sparked in her eye. “You know what that means!”
Spike gulped. “Another game?”
“Another game.” She nodded. “Same stakes as before. Only...” She hefted a sweaty breast, which seemed as big now as a hundred Spikes, and held its shadow over him. “You’re a little too small now to carry anything, so we’ll have to mix it up. I know just the thing!”
Her horn glowed, and in a flash of light, Spike found himself on a much softer surface than the hardwood desk. It was soft, bouncy, and warm, and the whole of it seemed to be covered in some kind of... purple... fur. He looked up to the ceiling. From the color, it looked like they were in Twilight’s bedroom. Twilight was lying on her bed, and he — he was on Twilight.
“Figured it’d be comfier if I could lie down,” Twilight boomed, her face blocked by two purple mountains in the distance. “The next game is mountain climbing!”
“And the mountains are...”
“These!” She picked him up by the scruff of his neck to give him an aerial view of her breasts — definitely mountainous at this point, and capped by swollen pink peaks taller than he was. She set him down at the base of her breast. “If you make it to the top, you win all the benefits from before. But if you can’t...”
Spike didn’t care to hear the end of that sentence. He knew the stakes. Victory had to come here and now, before Twilight put him through any more of her crazy games.
He looked up at the towering tit before him. If he won, he’d be taking Twilight much more seriously. And he’d put her on a diet. He’d made a couple of jokes about her udders before, but these were simply too big.
“Ready?”
He grabbed a tuft of purple fur from the base of the breast. It was slippery and sweaty, but if he could get a decent enough grip on it, it would be possible to climb it... Hopefully. “Ready!” he shouted.
“Go!”
Spike grabbed on and pulled himself up. One claw, one foot, other hand, other foot. He worked his limbs in a slow and careful rhythm, saving his strength and making steady progress.
“Keep it up, Spike!” came Twilight’s voice from the other side of the mountain. “It tickles!”
“Yeah, I’ll bet,” he grumbled, digging his claws in extra hard. Maybe Twilight had remembered, or maybe she hadn’t, but mountains were a dragon’s natural habitat. There was no way he was going to lose this, and she'd deeply regret everything she’d put him through after he won. Somehow.
He took a second to wipe his brow, taking a look at the purple-fur ground below to check his progress. Not a lot, but the only real obstacle at this point was just how much he had to climb.
A minute or two later, he’d made it a good ways up Twilight’s ‘mountain’. He was maybe halfway there, if the twin peak beside him was any indication, and he still had strength to spare. The faint hope in his chest swelled further. He was going to make it!
Unless Twilight had anything to say about it, of course — and she did. “This game’s looking a little boring for me,” she rumbled. “You can keep playing, Spike. I’m just going to make some of my own entertainment.”
“What’s that mean?” he shouted. No answer came, but the hand descending on the neighboring mountain gave him a good idea. He could see Twilight pulling and pinching at her nipple in the distance, and if her earthshaking moans were any indication, the other hand was somewhere further south.
“Keep going, Spike!” she groaned. “If you stop now, the... mmm, oh! The earthquake might get you!”
That was good advice, loathe as he was to admit it, so he returned to climbing. One claw, one foot, other claw, other — whoops. His foot slipped as the mountain jiggled under him. Twilight wasn’t directly interfering with his efforts to climb her, but her antics were definitely having an impact on his climbing.
Still, he could pull through. He set his foot back on the warm swell of her breast and locked it in place. One claw, one foot, other claw, other foot. He just had to maintain the rhythm, ride out the worst of the boobquakes, and he’d be golden. There it was, just ahead! The mountain was curving, and he could see the tip of Twilight’s erect pink nipple. He was going to make it!
But it wasn’t to be. Spike should have realized by that point that all hope was temporary. One claw, one foot, and a deluge of something thick and salty rained on him from above.
“Oops!” came Twilight’s voice. “Soooorry, Spike!”
“Agh!” He spat out as much of sticky liquid as he could, and used a free-hanging claw to wipe his eyes. What was all of this? Glue? No, Twilight had been lying here with him the whole time. She couldn’t have gone to get anything. Where was all of this coming from?
...Wait. His eyes widened as he looked to the shadow above him. Twilight had moved her sticky, cum-drenched hand just over his... and another drop was falling off.
This wave was even thicker and stickier than the last, filling his mouth and drenching him from head to tail in Twilight’s essence. It wasn’t glue, but it may as well have been, and the force of the drops were threatening to break his grip on the mountain.
“That’s cheating!” he sputtered. He’d spat out most of Twilight’s marecum, but the taste still lingered. “Twilight!”
“All’s fair in love and war,” Twilight sang. “You should be proud, though, Spike! I haven’t been this wet in months.”
Spike wasn’t feeling very proud at that moment, though. Particularly not as a third and final drop of marecum fell from her finger. The biggest of them all.
There was no hope. The sticky droplet tore his grip from the mountain and carried him all the way down to the summit, leaving him buried in a sticky puddle of Twilight-juice.
“I think that makes another win for me!” Twilight cheered. She brought her soaked hand down and stuck Spike to the finger. “Another game, Spike? I’m feeling really lucky today!”
“Please...” he gurgled. There should have been a no at the end of that, but there was too much gunk in his throat to say any more.
“If you say so!” Twilight said happily.
She leaned over and wiped him off on the sheet between her legs. From the puddle of marecum, Spike staggered to his feet. Warm... she’d put him some place warm. He brushed the juices from his eyes and stared up at the next ‘game’ Twilight had prepared for him: her own pulsing pussy, big enough to swallow him whole and already drooling in anticipation.
“You ready, Spike?” Twilight called, her boulder-sized clit throbbing with need. “‘Cause I am!”
“Ready...” Spike sighed. It was going to be a very long day.
Spelunking
"Gee, Spike!" Twilight giggled, impossibly loud and yet so far away. "You don't look so hot. You sure you want to keep playing?"
"Uuuunh," Spike groaned. The world seemed to swim around him, or maybe that was just the cum in his eyes. He was barely standing on both feet by this point, and the sweltering heat of Twilight's arousal didn't help. Tough as a dragon was, there was only so much he could handle before falling over. "No, I gotta..."
It was more than a matter of pride at this point. He did want to take a game off Twilight and finally show her who was top dragon around here, but if he didn't keep playing... He gave Twilight's massive, dripping vagina a good up-and-down look. By Celestia, it looked big enough to eat a full-grown dragon. How was he supposed to compete when he wouldn't even qualify as a snack?
No! He shook his head. If he didn't keep playing, there was a very real chance that he'd be this small for a very long time — if not forever. So long as there was even the faintest chance he could win, he had to keep trying.
Still. He shuddered as a long, thick line of drool ran from Twilight's quivering lips, big enough for him to drown in. It honestly did seem like the faintest chance.
"Tell you what, Spike," said Twilight, her tone positively dripping with smugness. "I've been on a pretty dominant winning streak, so I think we should amend the rules. We can't keep playing games forever, right? So how about we make this the last game and I'll grow you back either way. No change for your prize if you win, but if I win..." Her pussy gave him a playful wink, open and shut. "If I win, you'll have to keep me 'entertained' while I work on your antidote. Sound like a deal?"
Spike took a second to think about that. On the one claw, he didn't even want to imagine the consequences of losing and being forced to 'entertain' Twilight. On the other claw, what was the alternative? Losing game after game until Twilight got bored? He winced, thinking back to the crushing weight of a single Twilight tit, now the size of a mountain. He definitely wouldn't survive if he kept playing games.
And how long would it take for her to make an antidote anyway? This was Twilight Sparkle. She could probably brew up a new potion in under five minutes. Even if he lost, he wouldn't have to suffer all that long, and if — if — he won...
A grin crept slowly onto Spike's face. Now it could be for pride. Oh, the payback he'd get once he'd won this last game. If he won it. "Alright, deal!" he shouted up to her. "What's the game?"
"Spelunking!" Twilight said brightly. Of course. "Five-minute time limit. You're going deeeep inside me this time."
"A-and what?" Spike asked. Make her orgasm? That... that would actually work! Twilight was so obviously on the edge that even at his size he could bring her over. So long as he didn't die in there, he could do it! "Wait, let me guess," he said, trying not to sound too obvious. "I have to make you cum, right?"
"Nope!" Twilight said happily. "Just the opposite. You have to make sure I don't cum." Even without a good look at her face, he could practically see Twilight trying to stifle her laughter. "I'm giving you the advantage here, Spike. You're so small now, I'll hardly even feel you!"
"I don't know if that makes me feel better," he said. Twilight's pussy winked again, giving him a sneak peek of the cavern deeper in. Being so small would definitely be an advantage in the game, but it'd also make it all the more likely for him to get lost in Twilight's 'cave,' never to be seen again.
A thought struck him. "Hey!" he called up to her. "If I do this, that means you play fair this time! No masturbating while I'm in there!"
"Scout's... mmm, scout's honor, Spike!" Twilight said, absently fondling one of her tits. "It's not like I'd need to. The thought of my little troublemaker in there is aaaaall I'll need."
"O-okay then." Spike blushed. That wasn't entirely what he'd expected her to say, but so long as she played by the rules this time, there wasn't much he could argue. "Ready, I guess?"
"I sure hope so!" Twilight laughed.
Her colossal hand dropped down behind him and pushed him slowly toward the awaiting cave. "H-hey!" he shouted. He tried to push back, but his feet instantly slipped on a slick trail of Twilight cum, and her hand slid him ever closer to her titanic pussy. She pressed him up against her folds and fresh globules of piping-hot marecum dripped down on him from above. "Don't I get to choose when we start?"
"Nope!" And with that, a column-like finger shoved him in.
The rush wasn't too far off from a water slide, if water slides could squeeze him to death. Spike tried to grab hold of Twilight's finger as it retracted, but her undulating walls gripped him tight and the finger slid out without him, leaving him trapped alone in the darkness. Not that he could see anyway. Her juices were so thick and copious inside her that he had to keep his eyes permanently shut, lest he go blind. The only reminder he was even still alive was the thump-thump-thump of Twilight's heart above him, slow at first, but quickly building speed.
"Okay, okay," he whispered. He took a deep breath, trying to suck as much oxygen as he could from the humid atmosphere. "No need to worry. She can't get off if I just don't do anything."
He curled up into a ball and held still, careful not to rock the boat. For just a fleeting moment, he was able to believe he could wait out the game — right before Twilight's walls squeezed him like a fist.
"Tsk, tsk, Spike!" Twilight's voice thrummed around him. "That's not in the spirit of the game at all. You're going to play with me, one way or another."
Shit! Of course. He'd been smart enough to set masturbation off-limits, but that didn't even cut out half of the ways Twilight could screw with him. Twilight's pussy, already a tight enough space, contracted in another crushing squeeze, forcing him to scramble for safety.
"Ahhhh," Twilight groaned as he slid over her sensitive walls. The death-squeeze relented — for the moment. "Now you're getting it, Spike."
Shit, shit, shit! What was he supposed to do? He couldn't stay still, or Twilight would squeeze him into action. He couldn't keep moving, or Twilight would most certainly orgasm. The only thing he could think of was to ruin the moment for her. Enough pain to cut through the pleasure.
"Here goes," he muttered, extending his claws. He bit and scratched at every available inch of Twilight's pussy as he tumbled through, spinning like a roaring tornado of death. It was hard to find purchase on the slick muscle, and he bit more often at mouthfuls of sticky marecum more than he did Twilight, but he liked to think she could feel what he was doing up there.
And did she ever. "Ah... ah... Allllmost there!" The tremors immediately kicked into overdrive, and her pussy flooded quickly with more juices than ever before. "Y-you're not very good at this game, huh, Spike?"
It was all Spike could do to not break down and cry. Everything he did just turned her on further! Not even in this, her most sensitive of places, was he big enough to do anything that Twilight wouldn't feel like a finger over her clit!
Except one thing. One final trick he'd been holding up his sleeve. "Alright, Twilight!" he shouted, vaguely aware that she couldn't even hear him. "You asked for it!" He climbed to something approximating an even footing — or as even as it got in Twilight's undulating cunt — and took a deep breath. The deepest breath. And when he'd inhaled all he could possibly inhale, foul, musty, and thick as the air was, he let it all loose in a mighty gout of flame.
Twilight screamed.
The walls clenched.
And all hell broke loose.
"Whew!" Twilight panted, feeling almost lightheaded in the afterglow of her orgasm. "I don't know what you did, Spike, but that was incredible." She leaned over to look at the itty bitty dragon, waterlogged in a puddle of her fluids. "Do I need to say that you lost?"
"I..." He staggered to his feet and raised up a claw. "I surrender. I'm sorry, Twilight. I should've listened to you when you told me not to drink your potions."
"Aaand?"
"And..." His voice dropped to a low mumble. "And I promise to listen to you more from now on."
"Good enough for me!" She picked him up and gave him a good lick-off to clean the marinade of her own juices. "So, now that I'm properly de-stressed, I think I should get to work on that antidote I promised you."
Spike's face instantly brightened. "Wow, Twilight! Really? Right now?"
"Of course!" She slid on her bra and reconnected the clasp. "I'm a mare of my word. Win or lose, I'm going to get you back to normal size. But speaking of..." She grinned. "I did win, so you're going to have to provide the entertainment while I work on it."
"Pft," Spike snorted, a tiny jet of green flame erupting from his nostrils. "Okay, fine. So, what, I have to get you off for another five minutes while you make me an antidote? Whatever. No problem."
She did so love bursting his hot air balloon. "Who said it'd take that long? Given all the potions you tipped over and the interaction effects, it'll take me at least three days to figure out the proper antidote. Plenty of time to keep me company."
Twilight stifled a giggle as Spike's jaw dropped. "N-n-no! P-please!"
"You still have a lot of lessons to learn," she said as she stuffed Spike into her bra, pinned between the fabric and her fat, swollen nipple. "Better get to it!"
And with that, she gave a cheery whistle as she sauntered over to the door, and made her way slowly downstairs.
