Hot Swap

“Welp, that’s it for these old things,” Applebloom sighed, throwing the crumpled remains of the cotton window curtains though the open window of the clubhouse. They fell to the floor with a wet soggy plop.

Applebloom and Rumble had both ripped off the curtains with the intent to use them as impromptu clothes after tearing off their former digs in a lust fueled romp within the clubhouse. Unfortunately the aged fabric was coarse and itchy. Not even the threat of nudity was worth wearing old curtains for more than five seconds. So the two had used them as towels to dry off their sweaty bodies.

“I just don’t want to be seen like this,” Rumble replied, preening her wings of the dried cum that had landed there twenty minutes ago.

“Ya won’t. We’re in a nice, secluded spot in the orchard. Not to mention since the Crusaders stopped using it we haven’t exactly been keeping the grass cut and the shrubs tidy…” Applebloom said, scanning the area. At her newfound height he could see pretty well and since the vegetation was so overgrown it actually wouldn’t be feasible for even an in flight pegasus to spot them.

In fact the trail leading here was mostly overgrown to the point of total obscurity. It was a little sad.

Rumble slowly wiped off the the last of the matted sweat between her huge J-cup breasts and tossed the rag aside as Applebloom looked around. Standing next to this Adonis of a stallion was a stark realization of how much they’ve changed in the past hour. Applebloom was seven feet of powerful, sexy stallion and Rumble was five feet of small, sexy mare. This discrepancy between their heights was huge. Rumbles eyes came to about an inch below Applebloom’s beefy pecs. And further down…

Since they’ve eloped, their bodies more or less relaxed. Rumble wasn’t craving sex the minute she’d woken up from their impromptu nap and neither was Applebloom. Out in the open the light breeze had helped them cool off. However, the sun was still beating down and there was no shade. At the moment Rumble was staring at Applebloom’s groin again: the sheath housing the two-foot pole of cock that was just slamming into her rear an hour ago wasn’t even fully retracted. About 6 inches of it were hanging out there, resting on a pair of softball sized nuts.

“Well, the coast is clear,” Applebloom finally said, satisfied he couldn’t see any ponies nearby.

“What’s your point?” asked Rumble tersely.

Applebloom balked. “Huh?”

Rumble spread her wings and flew up to meet Applebloom eye to eye. “We can’t turn ourselves invisible. How are we going to get home without being spotted? How are we going to hide from our family and friends until midnight? I know we aren’t staying in the clubhouse after THAT so… what’s the plan?”

“Uhh,” Applebloom blinked, trying to not stare at the twin pair of fat breasts dangling right in his face. “W-well, ah reckon we could make some clothes out of the leaves-”

“Are you joking?” Rumble interrupted, cocking an eyebrow. “We ripped our old clothes. The curtains are toast. But leaves?”

Applebloom scratched his red mane. “Why do y’all think that’s a joke?”

“How do you bind it together without string or rope? How do you get enough to make it stable and cover our bodies…” Rumble sighed, “How do you know for sure that you aren’t strapping poison ivy onto your penis? Do YOU want an itchy rash on your balls?”

Applebloom shuddered, a familiar arousal building in his body. Even being lectured at, the sexual attraction he felt to Rumbles titillating body was insane. He felt his cock stir and a few inches of meat slip out of his sheath.

“-plus I don’t want an itchy rash on these,” Rumble flipped her body from horizontal to vertical and hefted her enormous grey tits. “Plus I don’t know about you but moving fast with THESE probably hurts! That’s why Scootaloo wears sports bras! Even though she doesn’t have big fat monster tits they still move!”

“R-Right… listen. Calm down a lil’ now. I hear ya. Yer right,” Applebloom was staring at Rumbles tits, not her face. The breeze died down and Applebloom could smell the arousal wafting off her. “Odds are if we head home now we’ll be spotted easy. Sundown is at… seven today. We could just wait for that.”

“Don’t you have like, a bigger clubhouse to stay in?” Rumble let her tits go and planted a finger in Applebloom’s chest. It was partly to make a point but Rumble was starting to feel horny as well and mostly just wanted to touch Applebloom’s big sexy body.

“No…” Applebloom swallowed, feeling his cock rapidly plumping up. Any second now it would brush against Rumbles calves. “We’ll just stay here and wait. The last ingredient needs to be exposed to the n-night air anyway. It’s not a big deal.”

“Actually, it kind of is a big de-”

Applebloom put his hand over Rumbles mouth and pulled her into his chest, stepping backwards into the thicket closest to them.

“Mpmmpff?” muffled Rumble into Applebloom’s palm.

“Applebloooom?” called out Sweetie Belle’s light, airy voice. “Are you heeere?”

“Why would she come back here?” questioned Scootaloo, following Sweetie into the small clubhouse clearing. “I think it’s been a year since we visited the clubhouse.”

Rumble panted against Applebloom’s hand. Scootaloo and Sweetie Belle had walked into the clearing and were milling around. Appleblooms heart was pounding in her chest, both out of fear and from having Rumbles ripe body pressed against him like this.

“We always used to meet here when something’s wrong. We haven’t seen Applebloom since brunch!”

“Well yeah, you said it sounded like she had bad diarrhea,” snorted Scootaloo, climbing up the stairs. “Hey, the windows are open! Somebody’s been in here!”

Rumble could feel Applebloom’s heart pounding against her breasts. A strong, thump-thump that was rapid and insistent. Applebloom released his hand from Rumbles mouth and let the small mare breath.

“What do we do?” whispered Rumble, her forehead breaking into a sweat.

“Shhh,” Applebloom hissed, re-adjusting his grip holding onto Rumble. In an effort to make it easier, Rumble pressed himself up closer to Applebloom, wrapped her legs around his beefy trunk and threw her arms around his neck for support. Now they were as close as they possibly could be and Applebloom was loathe to keep holding Rumble so carefully. She was light already being a Pegasus. Almost like on autopilot, Applebloom caressed Rumbles backside as the other two crusaders investigated the clubhouse.

“Hey Sweetie! Somebody was rutting in here!” called Scootaloo.

“What!?” Sweetie Belle alighted herself in magic and floated up to the railing. “Really?”

“This place smells like sex. Like, hours of sex,” continued Scootaloo, “There must have been like a secret orgy up here.”

The close contact between Applebloom and Rumble was resulting in much quicker mounting arousal. Rumble began caressing Applebloom’s strong back muscles, and panting slower, deeper. Applebloom hadn’t stopped himself; and the result of his building arousal was now prodding between Rumble’s cushy butt-cheeks.

Rumble pulled her face away from Applebloom’s neck and stared into his golden yellow eyes. Her mouth was open slightly and giving Applebloom serious bedroom eyes. Applebloom flexed his groin in response, his erection pressing against Rumbles rear insistently. This was really really hot being like this but at the same time, Applebloom did not want to get caught right now, even with this unbearably sexy mare in his grip slowly grinding her ass on the tip of his cock.

“I found some weird bowl in here too!” Scootaloo said in surprise, holding up the mortar.

Applebloom flinched and loosened his grip on Rumble, who slid several inches down onto the hard cock probing her pussy.

“EEe!” Rumble squealed.

Applebloom’s hand clamped over her mouth, but not fast enough.

“What was that?” Sweetie Belle glanced in their direction.

Scootaloo put down the bowl back on the desk and squeezed back out the small doorway. “It sounded like a baby piglet. You think it escaped from the farm?”

“Probably. There aren’t any wild pigs out here…” mused Sweetie Belle.

Applebloom gingerly backed away from where Rumble had squealed, wincing as she did. Each step caused Rumble to slide another inch down onto Applebloom’s throbbing shaft, and each inch drew a small mewl of pleasure from the writhing Pegasus impaled on that cock. It was already difficult moving around in a big new body. Doubly so when you had more than a foot of dick stuffed inside a sexy mare.

As soon as Applebloom stepped behind a double wide dead apple tree the brush that was obscuring his massive body was pushed aside by Sweetie’s magic.

“I don’t see anything,” Scootaloo peered into the thicket.

Sweetie Belle rolled her eyes. “Go LOOK maybe?”

“My eyesight is just fine you know. I can see great from here!”

“But you can’t HEAR anything,” Sweetie Belle retorted.

Appleblooms heart jumped.

“Fine, Fine.” Scootaloo jumped from the railing and landed, walking over to the shrubs.

Rumble twisted and turned her body on Appleblooms shaft, making small, almost imperceptible moans of pleasure. Applebloom reached his hand up to silently shush Rumble. In order to do so Applebloom let go of Rumbles ass and ceased supporting her, which caused the quivering pegasus to sink a few more inches right down to the thick medial ring.

Applebloom had to bite down on Rumble’s mane. It felt so fucking good plugged up inside Rumble again. Warm, wet, tight as a vice. This cute mare writhing on his massive cock as another equally sexy friend was wandering closer to their hiding spot. It would almost be worth it to be caught. Just to show off how big and strong and sexy he’d become.

Rumble was equally parts worried and aroused, but now she just wanted to get off. With great care she slooowly slid herself up a few inches of Appleblooms shaft, before dropping down just as slowly coupled with a strong rippling squeeze. The cock was so big that it didn’t even fit all the way inside. That thought turned Rumble on so much that she felt her orgasm upon her even before she could realize it.

Applebloom clutched the mare cumming on his cock tightly and covered her mouth again, still desperate to not be caught. He could HEAR the patter of her pussy juices on the leaf litter below them. It was like a small rainshower.

“I don’t hear anything over here,” Scootaloo said, uncomfortably close by. “It smells like yard work.”

“You find anything?” Sweetie called out.

Applebloom bit both their manes as Rumble came a second time. The repeated orgasms were too much to bear and Applebloom could feel his own orgasm boiling in his loins. His cock flared and his muscles tensed.

“Nah, I didn’t find anything!” Scootaloo turned and walked back to Sweetie Belle.

Applebloom came even harder than before. His pulsing cock spewed what felt like gallons of his potent seed up into Rumbles needy pussy. It was so much that Applebloom could feel Rumbles belly swelling against his rock hard abs with each spurt. That only served to double his output and Applebloom buried his face into the top of Rumbles head.

After what felt like a minute the deluge of cum ended and Applebloom felt like he could breathe again. He twisted his ear and hearing no voiced decided to carefully lift Rumble off his cock with a goopy-

Schlllurrp

Rumbles pussy loudly popped off Appleblooms softening shaft. A hot gush of cum and other juices followed. Rumble stood shakily for a moment and then fell to her knees, panting like a racer finishing a mile run.

“Ah can’t believe we didn’t get caught,” Applebloom said, catching his breath. “Why did y’all do that?”

“Hey!” shot back Rumble, “You could have put me down... at any time. I have legs… be honest. You wanted that to happen too, right?”

Applebloom opened his mouth to retort but instead thought of that for a moment. There was opportunity to set Rumble down but instead… Applebloom wanted her on him. Close to him. Pressed up against him. And he wanted to fuck.

“I wanted it too… we both wanted it,” Rumble said, tenderly rubbing his fat breasts. “It felt sooo good.”

“We did almost get caught y’know.” Applebloom said, glancing at her cock. Despite having just unloaded a couple gallons of cum it wasn’t going soft. It dangled down between her legs covered in both semen and mare juices.

“But… we didn’t” said Rumble, watching Applebloom pluck a leaf off a nearby shrub and wipe one of his balls clean.

“Stop!” shouted Rumble.

“What?”

“What did we just talk about with plants?”

“My cock is covered in… this stuff. I want to wipe it off.”

“Then I’ll clean it for you,” Rumble said excitedly.

“With whaa-A-a-a-A-”

Without warning Rumble was licking Applebloom’s cock, gripping with one hand by the ring and the other planted on Applebloom’s muscled leg. Applebloom watched with awe at how eagerly Rumble went about it. Long licks along the shaft. Short licks by the ring. It was incredibly erotic.

“Wow… what we just did was really hot an’ all but this is somethin’ else,” commented Applebloom, who was really starting to enjoy the clean-up. “Jus’ be glad we didn’t get caught. We’d have a lot of explaaaining to do.”

“Mhmm,” Rumble hummed, having finished one side of the shaft and now working the other. It was starting to get hard again and Rumble was shivering in delight feeling the soft shaft hardening under his ministrations.

Applebloom continued. “And ah ain’t going to lie, it feels really good being a big ol’ stallion. Always wondered what it’d be like to be in Mac’s horseshoes, but this is me bein’ bigger than him.”

“Mmmm,” Rumble was half-listening, licking the last bits of cum around the tip of Applebloom’s growing shaft. It was nearing full mast already and pre was bubbling at the tip.

“So when ah say I really appreciate what yer doin’ I tell you I mean it. It’s not like anybody else was going toooo!! Ahh!”

Rumble was outright bobbing her head on the first few inches of Applebloom’s fully hard shaft and swirling her small tongue around the head. A few bursts of pre jettisoned down her throat and she moaned at the salty taste.

“Oh FUCk that feels soooo good,” Applebloom shrugged his shoulders and sighed happily. He placed his hand on Rumbles head and leaned back against the tree as Rumble serviced her cock, bobbing her head in short quick motions and fondling his large balls.

“MMmmmmhmmm,” Rumble inhaled and swallowed several more inches of cock, feeling the dark obelisk stretching his mouth and throat wide. With one hand fondling his swollen nuts and the other rubbing the shaft it wasn’t even that long before Rumble was able to draw out another orgasm from Applebloom. She could feel the rapid pulsing of his cock. The flare widening and bulging out to the point it was visible through her neck. And in seconds Applebloom had both hands grasping Rumbles hair and was dumping another couple gallons of cum down her throat. It wasn’t even ten minutes after his last orgasm and Applebloom’s output had not changed. In fact it might have even increased.

Applebloom gasped as the last few drops of his orgasm finally ended. He looked down at the sweaty grey mare with her ass sticking out and most of his cock down her throat, and gently began pulling out. It didn’t feel sore or painful in any sense of the word. As Applebloom pulled the tip out of Rumbles mouth he realized that his shaft didn’t look or feel any less hard. It bobbed in the air happily as if the last orgasm didn’t even happen.

“If we keep this up ah’m not going to have a mind to blow by the time we switch back,” Applebloom wheezed, grasping his rigid shaft. It was so big. And most of it was just stuffed down Rumbles teeny tiny mouth.

A jet of pre squirted from the still flared tip and fell somewhere over Rumbles shoulder.

“Thanks for the blowie,” Applebloom said, not sure what to do about this rock hard shaft.

Rumble just laid on the ground flat on her back, playing with her big soft breasts. That last load had swelled Rumbles belly up to the point past where it looked like she’d had a large meal. It wasn’t obscene but it was noticeable and made her belly jiggle around like her breasts were doing right now.

“I don’t know what came over me. I saw your cock and I just wanted it in me again,” Rumble said with a sexual moan, “You taste so gooood."

Applebloom’s cock twitched. It was like being hypnotized. Staring at this mare. Heaving chest capped with fat, dark nipples, thin waist, wide hips and now that cum bloated belly. It was hard not to stay aroused.

“Fuck me again."

“What?!” said Applebloom. He heard what Rumble said, but wanted to hear it twice.

“Fuck me, now,” demanded Rumble, spreading her legs. “I need that in me again. We're alone. Let's do it some more!”

Applebloom eagerly walked over, lined up his cock and glided right inside of Rumble yet again.

“Ahhhhnnnngh!” Rumble arched her back and moaned, forehead pressing up against Applebloom’s muscular body. “Yessss… ohhh, fuck meeee!”

Applebloom obliged and began thrusting in and out, in and out at a much more rapid breakneck pace than before. Rumble was not quiet. She moaned, groaned, squeaked and squealed at every powerful thrust. It was unreal. Sex just felt too good to pass up and they both loved it.

“Harderrrr,” Rumble squeaked out, twisting in ecstasy on the ground beneath Applebloom.

Immediately he picked up the pace, performing a much more diligent and powerful fucking. Applebloom craned his neck to just watch and delighted at watching Rumbles entire body wobble and shake with each strong thrust. It was so erotic that he felt his orgasm already building. Applebloom reached down to fondle Rumbles erect wings and squeeze the smooth flesh under the joints.

“Harderrrrrrr!” Rumbles tongue lolled out her mouth as Applebloom really started pounding his hips. His fat balls slapped Rumbles huge ass with impunity and the air was filled with the steady slap-slap-slap noises of their lovemaking.

Hard--fffffffuuuck! Yes!!!” Rumble seized up and came, feeling Applebloom’s shaft swell and erupt another hot load of cum inside of her. “Yesyeysyesyesyeysyesyesssss,”

Applebloom pulled out before he was finished to stand up straight and grasp his cock, aiming at Rumble. Hot, thick ropes spewed out and marked Rumbles body. A shot on her face, another for each fat breast, two more on the belly and finally one that traveled the entire length of his body leg to neck. It was the hottest thing he could think of doing, and the results were more erotic than he imagined.

Applebloom briefly admired the sun shining on the globes of cum he’d painted Rumble with and collapsed on his back and closed his eyes.

Minutes of silence ticked by. The only things audible were the chirping of birds.

Light hoofsteps caught Applebloom’s ear and he felt the unique sensation of Rumble straddling his midsection.

“Hard enough for ya?” he grunted wiping his forehead with the back of his hand.

“Sweet Celestia yes,” Rumble said stretching his wings,” It absolutely was. Thank you.”

“Anytime,” Applebloom said, cock twitching. “I just thought of something Rumble. If everyone were naked all the time, sex would just be easier. No clothes to get in the way, or to wash. And if somebody were turned on by you it’d be easy to tell. There’d be a lot less guessing games.”

“What are you talking about?” Rumble giggled, her small hands resting on Applebloom’s abs. “Society isn’t going to change because we had great sex.”

“AMAZING sex,” Applebloom pointed out. “And yea, you’re right about that… I’m just talkin’ ah guess. I don’t know what else to talk about,”

Rumble remained silent.

“Just looking at the sun it looks like it’s only… I want to say three o clock?” mused Applebloom. “Gosh we’ve still got so many more hours to go. Rumble? Why y’all bein’ so quiet?”

Applebloom tilted her head up quizzically.

Rumble had hefted her right breast up and was suckling her nipple.

“Holy- What’re you doing?!” Applebloom’s body lurched in surprise.

Rumble met his eyes and for another couple of seconds continued sucking. She released her nipple and let her breast fall and slap against her belly with a lewd smack. After that last load Rumbles belly had grown to be even larger than before. It was big enough that it began to part her breasts and jiggled enticingly with every subtle movement despite how stretched and rounded it was.

Applebloom’s cock started getting hard again.

“Are you still horny?” Applebloom asked incredulously.

“Yeah,” replied Rumble, idly rubbing his very swollen middle. “Are you not?”

“Ah,” Applebloom paused, and realized he was. Almost like clockwork it was stirring to full mast. Already it was brushing up against Rumbles outstretched wings. The base of his cock starting to nestle between Rumbles prodigious rear.

“You’re staring at my stomach,” Rumble said bluntly, hefting her big jiggly belly. “Do… you like this or something?”

“Ah mean, look how much I put into ya for that to happen!” Applebloom said, his hands traveling up Rumbles legs. “Can’t help but look at ya,”

Rumble could feel it again. The familiar solid erection sliding up her back. Rumble licked his lips and ground his ass against it with a sultry moan. She stood up and Applebloom noticed the wet sticky matting of her fur on the inside of her legs. All that cum he’d filled Rumble with was practically oozing out of her pussy. The sight was incredibly erotic.

Not wanting to wait another second Rumble flapped off of Applebloom’s midsection and descended onto the erect tool waiting for her.

“Oh YES! YES!” cried Rumble in sheer ecstasy, sliding straight down onto most of Applebloom’s cock. “YES!!”

Applebloom watched that svelte mare sliding down nearly the entire length of his cock until even hitting the medial ring. Rumble was so short, and the cock so big, that she needed to crouch just to be fucked in a comfortable position. It was too big for the whole thing to fit at this point but did Rumble try. She bucked, raised herself up and dropped herself down, desperate at this point to take the whole thing.

It was a sensation that Rumble felt she was never going to get tired of. Being filled up to the brim. Being fucked by a massive stallion. It felt natural for some reason. Where the first time was a primal, alien feeling of penetration now everything about it felt right. This deliciously full sensation of her body being filled up was too good and the mind-melting orgasmic nirvana that followed was the cherry on top of what this amazing sex was. One was building up inside her right now as she bucked up and down with glee.

A few minutes of frenzied, ball-slapping mind-blowing sex later Applebloom was cumming yet again, gripping Rumbles hips and unloading what felt like his biggest load yet. Rumble’s tiny body shook and she threw her head back and screamed her orgasm out unabashedly, a hot gush of her juices splashing out onto Applebloom’s lap. The added fluid lubrication allowed her to sink just a few inches further and take the medial ring into her already stuffed pussy as volleys of hot cum unloaded into her already overly stuffed womb.

In seconds Rumble’s already swollen belly expanded in jerking spurts. Every pump of cum into Rumbles womb stayed there, plugged by the tip and the ring and in no time at all her belly was jiggling to the size of that a pregnant mare.

Applebloom looked up during the seemingly endless volley of his orgasm just in time to see Rumbles belly button pop out out from the sheer amount of cum being pumped full into her womb. He had to reach out and touch it. Just to feel the swollen jiggling mass expanding from the force of his never-ending orgasm.

Finally the deluge ended, and Applebloom could feel the volleys of semen slowing down. Eventually his cock softened to the point where Rumble could begin to move, and she slipped herself out with a wet POP!

A verifiable deluge of sticky white cum followed, spilling out onto Applebloom’s sheath, balls and stomach. Rumble took a janky step forwards and eased down onto Applebloom’s body, snuggling up to the stallions chest once before.

“Oh Sweet Celestia,” Applebloom breathed, head swimming from both the sun’s heat and physical exertion.

“Sex feels sooo goood,” crooned Rumble, a dopey smile on her face.

The two layed in the grass under the sweaty sunlight, enjoying the company of each others warm bodies. Applebloom caressed his lovers full, taut belly and his mind flashed back to what just inspired.

And… felt his penis starting to stir in his sheath.

“Rumble…?” began Applebloom, a beam of lucidity striking his thoughts. “What are you thinkin’ about right now?”

“More sex,” replied Rumble matter-of-factly. “Are you thinking about that too?”

“...yeeah, ah am. Plus ahm not tuckered out after all that,” Applebloom felt his groin flex, a few more inches of cock spilling out. “This has to be a side effect of the potion. Us fuckin’ like rabbits out in there and now out here.”

Rumble sat up, bracing herself with an outstretched arm. “...you’re right. That’s all we’ve done and… wow. How many times have we had sex?”

“We fucked five times,” Applebloom stared longingly at Rumble’s distended navel and rounded belly. Now there was even a thin dark line traveling vertically down her belly through the belly button. She looked eight months pregnant.

“And I sucked you off once,” noted Rumble, fondling her fat breast with her free hand.

Applebloom saw and felt his cock rising to full mast, spilled cum sliding down the spongy flesh. “Alright, we need to get up and do something in the clubhouse. Whip up another potion or SOMETHING.”

With a grunt Applebloom hefted himself up into a sitting position. He almost reflexively grabbed his cock but resisted, instead choosing to wipe off some stray blades of grass on his legs.

“Something what?” Rumble asked quizzically, tugging on her nipples.

“Something that maybe stops us from being so damn horny!” exclaimed Applebloom. “If ah don’t we’re going to end up laying around here rutting like rabbits until your belly is so stuffed full of cum that ya can’t walk anymore!”

Appleblooms cock lurched and shot a jet of pre-cum onto the ground in front of him.

“Yeah… let’s uh. Let’s just get inside and do that,” Rumble rubbed his head. “I need to be able to think about something that isn’t sex with you.”

“Right, and maybe I can figure out exactly how this damn potion I brewed actually works. Cuz you and me stopped growin’ and shrinkin’ at this point,” Applebloom switched to a standing position and gave his balls a quick fondle. “Let’s go.”

Sweaty and sexually charged, the two of them stood up and walked over to the cutie mark crusaders clubhouse.
