Little Mare, Big Family

2 Months Later (10 Months Pregnant)

“Hey, Boss!” A pegasus stallion waved at Rumble. “Back already?”

Rumble waved back, a happy smile on his face. He whistled as he set to to work gathering the bigger, more stubborn clouds.

Another stallion came up beside the first. “Aw man, Rumble’s back? I thought we’d finally got rid of—I mean, I thought he got that big, fancy promotion! Does that mean we actually have to do work now?”

“Damn right, ya do!” Rumble rubbed his hooves together, gathering pegasus magic into his hooves. “Listen up! Cloudsdale wants me to manage Ponyville’s weather team until they find my replacement! Chip Cutter, go wrangle up the stray clouds on the Everfree border. Cloudsdale wants us to have a rainstorm tonight. Crackle Pop, go tell the newspaper! Rain starts at four p.m!”

The two stallions saluted, flying off in separate directions. Rumble set to work gathering more clouds, forming a mass in minutes that would’ve taken most pegasi an hour.

The morning passed, the weather team working hard to get ready for the storm. Rumble oversaw thing while also doing a lion’s share of the work, their progress going smoothly.

Eventually, the team broke for lunch.

“Aw, horseapples…” Rumble rummaged through his saddlebags for the third time. “Don’t tell me I forgot it. I coulda swore I packed it—”

“Oy, Boss!” Crackle Pop pointed to an orange dot flying up from below. “I think your lady’s coming up!”

Rumble looked over the cloud’s edge. Sure enough, Scootaloo was swiftly rising to their height, ascending in a lazy circle on a thermal. Her wide wings stretched out far to either side, her violet mane and tail waving like windsocks.

“Erm, I don’t think that’s Scoots,” Chip said. He’d gone to school with them, and knew her past. “She’s never really been able to—”

“It’s her.” Rumble closed his saddlebags, motioning Chip Cutter over. “You haven’t seen her in awhile, have you?”

Chip furrowed his brow. “Well, no but… how can that be her?”

Rumble laughed. “You’ll see.”

A moment later, Scootaloo was at their altitude. She exited the thermal and coasted over, landing easily on the cloud.

“Don’t mind me!” Scootaloo shrugged off her saddlebags, making a beeline for Rumble. “Just making a delivery.”

Several jaws dropped, Chip’s most of all.

“Holy shit…”

It was pretty common knowledge that Rumble’s wife was a runt of a mare. Further adding to it was that Rumble was the largest non-alicorn pony any of them had ever seen, so the size difference was even more extreme.

The mare that stood before them, though, was no runt.

“SCOOTALOO?!” Chip rubbed his eyes. “Is that you?!”

Scootaloo turned at the familiar voice. “Chip Cutter!” She waved at her old classmate. “Wow, I haven’t seen you since the wedding! How’re you liking the weather team?”

Chip stammered and spluttered. He associated that scratchy voice with a petite tomboy with wings like a hummingbird, not a massive maternal mare nearly twice his size! Her long mane and coat had a blooming sheen, her wings powerful and developed. The flight muscles in her back rippled and flexed, even moreso as she stretched out like a cat. And her burgeoning, swaying belly hung low between her legs, its wide, round shape jutting out well past her hips.

Scootaloo ruffled his mane as she passed. “Don’t keep your mouth open too long. You’ll attract flies.”

“Hey, hun!” Rumble came up to nuzzle her. “Sorry you had to come up here.”

Scootaloo rolled her eyes as she gave him his lunch. “I get to do something I’ve spent my whole life wishing I could do. You don’t need to apologize.”

Now the weather team was gawking even harder. This was Rumble’s wife?! The dwarf everyone talked about?! She was even TALLER than their huge-ass boss!

Scootaloo leaned down to whisper in Rumble’s ear. “When will you be home?”

Her sultry tone sent shivers down Rumble’s spine. “R-Rainstorm’s scheduled for four. Gotta stay ‘til then.”

Sneakily, Scootaloo’s hoof snuck up to squeeze his toned rump. “You should say you’re gonna have lunch with me so we can sneak in a quickie.”

Rumble nearly bit his lip so hard it bled. “You think we can make it quick?”

“Mmm… we can try… “ Scootaloo’s hoof inched lower, creeping closer to his balls. “I’ll be in your that piddly little office of yours. Don’t keep me waiting, Shorty. I wanna rut your brains out again.”

Scootaloo cantered away towards a squattish looking cloud structure a hundred yards away. Rumble couldn’t help but gaze longingly at the gentle sway of her hips, the pear-shaped orange mass swaying beneath them.

“...Hey, Boss?” Chip asked.

Rumble swivelled his ears.

“Does Scoots have a sister, by chance?”

“A big sister… of sorts.” Although Rainbow Dash was now more the little sister these days. “Enjoy your lunch, fellas. I’ll be in my office.”

————————

Inside of Rumble’s office was a slew of boxes and posted papers—standardized sheets that had to be on premise, but safely put where the wind wouldn’t blow them away. Once a job was complete, the cloudbuilt structure could be moved to the next location with a few strong kicks. Rumble had barely been in his office before he’d been promoted, and hadn’t ever gotten around to expanding it to fit his size. As such, it was just a ten by ten square with no windows, one chair and one desk.

Rumble opened the door to find Scootaloo behind his desk, inspecting some papers pinned to the wall. Her massive body consumed the entirety of the far wall, and her bulging belly had forced the desk out of her way. The sound of him entering got her attention.

“That was three minutes.” Scootaloo pretended to pout, backing out of the corner she’d squeezed herself into. “I was starting to think you weren’t hungry.”

The bag lunch fell from Rumble’s mouth. “You know, I was hoping I’d get a chance to eat out.”

Scootaloo snickered. With how large they both were, the office might as well had been a closet. Her belly and folded wings pushed against everything in her way until she finally, she had her plush, jiggling rump right in front of Rumble’s nose. At her current height, he only had to just bend his neck to reach her nethers. But it wouldn’t be long before he could pleasure her while standing...

“Clock’s ticking.” Scootaloo wiggled her ass in his face.

It wasn’t like she had to twist his hoof. Rumble dove right in, his large, wide tongue plunging into her eager cunt. She was already hot and quite wet, so he wasted no time lapping and wriggling his tongue about, swirling in and around her plush slick lips like an overeager colt with an ice cream cone.

Scootaloo moaned, her snapping her wings open. Now at fifteen feet, her wingspan more than matched even Princess Celestia’s. They smushed against both walls in the room, skirting the floor as she stamped her hooves. In a hot minute they both were sweating and panting, not only from exertion, but from the heat their large bodies gave off in the tiny space.

Rumble smacked Scootaloo’s ass, her cheeks jiggling like a water balloon. Scootaloo yelped and shook her mane, her labia winking and dripping. Rumble spanked her a few more times, this time punctuating it by wrapping his lips on her ping pong ball-sized clit and flicking his tongue.

Scootaloo shrieked. Her front legs bent forward, her whole body shaking with the force of her orgasm. A gush of marecum squirted all over Rumbles face and neck, and he buried his snout in her pulsing snatch, lapping like there was no tomorrow.

But eventually, Scootaloo’s orgasm subsided, her heavy panting easing up. “That… was good…. hah… but it’s not….. hah… hah... what I came here for.” Scootaloo flicked her tail to the side, her flower winking again.

Rumble flapped his wings and mounted Scootaloo. Or at least, he tried to. His wife was so much bigger than him now that he couldn’t even properly rut her! Scootaloo giggled at the sensation of his hard cock sliding against her belly—he couldn’t even reach her ass!

“Damn it!” Rumble snorted steam, slipping off her.

“Get on your back, Shorty,” commanded Scootaloo. She straightened and turned around, careful not to knock into anything. “I’ll be on top.”

Rumble gulped, looking up to his enormous wife. “Uh… you’re a lot bigger than me now, Scoot… Bigger and heavier…”

Scootaloo flexed one of her forelegs, the thick, rippling muscle popping up through her sweaty orange coat. “Stronger, too! S’one of the perks of all this... but you are NOT a fragile stallion Rumble. Don’t worry!”

An inkling of worry remained in Rumble’s mind… but he REALLY wanted to have sex with his wife right now. His eager, throbbing horsecock agreed, too. His lusts won in the end, and so Rumble laid down flat on his back, his boner standing straight up like a twitching black flagpole.

Scootaloo grinned. If she looked tall on all fours, she had to seem gargantuan from a low vantage point. The look on Rumble’s face supported this idea as she swung her long, sturdy form over him, his cock throbbing even harder.

“Just lay there and relax, babe,” Scootaloo said. “I’ll do all the work.”

Scootaloo’s gigantic orange womb swayed in front of Rumble’s face. Quick as lightning, he sat up to plant a few smooches on it. Scootaloo giggled and took a step back to position herself, and one double check later, she lowered her rear, feeling for Rumbles cock by touch.

Tab A found Slot B, and Scootaloo sat down.

Two realizations immediately hit Rumble. The first was that for the first time in their entire relationship, Scootaloo was able to take his entire length. And in one go, no less! She was amazingly warm, incredibly wet, and it made his dick harder than diamonds.

The second was that Scootaloo was stupendously fucking heavy.

Rumble could barely breathe. His world was nothing but orange as his eyes bugged out, his frame sinking more into the cloud.
“Ohhh, yeeeaaah...” Scootaloo’s inner muscles flexed and massaged Rumble’s thick tool, plunged so deeply inside her. Every muscle in her body was stronger, and the ones in her pelvis were no exception. “I needed this SO baaaaaaad...”

“Scoot!” came a small breathless gasp from below.

“Rumble…“ she bit her lip, running a hoof through her long, silky mane. “Oooooh, you feel so GOOD! FUCK!”

Rumble wheezed. His cock felt amazing, but everything else was being crushed! And he couldn’t even get Scootaloo’s attention with her titanic belly blocking her view! He finally had to reach up and tap it three times on the big warm mass to just to alert her.

“Mmmm? Oh!” Scootaloo adjusted her hindlegs and sat on them a little better. When she was her original size, she would tap on him three times if his size was giving her discomfort. The tables were turned, but she still remembered their code.

“Jeez, you are HEAVY!” Rumble gasped. Sweat dripped off his light gray coat, the office fast now a sauna. A lewd sauna, smelling of sweat, sex, and need.

“I’m only going to get heavier~” Scootaloo’s tongue lolled out her mouth. “Ooooh, you’re going to look like a little colt to me soon...” She gave a rippling squeeze around his turgid cock. “You’re gonna knock me up again and again… nggh… filling me up with MORE foals each times… mmhhh… you’re gonna make me so BIG…”

Rumble didn’t respond. He was getting close to his limit already. How could he have known sex where he didn’t have to move could be so rewarding?! Scootaloo was doing all the work, wiggling and squeezing, her velvety walls clamped down on his cock. He could feel his balls bloating and tightening, his head flaring deep within her...

Scootaloo was drunk on the sensations, mind foggy and fuzzy. To be so much bigger, to be so much to handle! Before, it was her that needed delicacy in their sexual excursions, her that was pinned to the bottom under a much larger lover! Now, SHE was the dominating force! She lifted herself off Rumble dick and bounced, her oversized clit bumping against his medial ring, and when it did...

“FUUUCK!” Scootaloo went over the edge. Her tunnel flexed and contracted, and Rumble followed right after, gripping her huge belly as he pumped her full of cum. Jet after thick jet he shot into her eager pussy, but Scootaloo took it all, squeezing so tight that not a single drop escaped her.

After the tenth and final spurt he relaxed, panting like he’d just run a marathon. Scootaloo had dropped her full weight on his pelvis again, but he didn’t care. He just felt too good. Life was too good.

What felt like hours later, the waves of pleasure finally ebbed. Scootaloo let out a long, satisfied sigh, standing shakily back up and relinquishing her prize. Rumble’s cock slipped out of her with wet schlick, followed by pints of their cum all over the cloud floor.

“That… was good.” Scootaloo smiled, body dripping with sweat and reeking of sex. In the dim light of their office, she almost looked like she was glowing.

“Agreed,” Rumble said. He was still on a sexual high himself. “What… time is it?”

Scootaloo stared at the wall clock. After ten seconds of zoning out, she registered the time.

“Five to two.”

“…Back to work.” Rumble shakily got to his hooves, almost falling into her. She caught him with one of her downy wings.

“Gimme a kiss, stud.” She crouched to be at Rumbles height. They made out, deep and long, Rumble’s tongue dominated by Scootaloo’s now larger one.

“And one for the kids,” Scootaloo said, breaking the kiss.

Rumble planted four kisses on her bulging side. He smiled when he felt a hoof press against his face.

“Won’t be long now…” Scootaloo patted her baby bump. “Hey, I’ll see you later at home. Make sure you’re on time, ‘cause this momma’s making a lot of food tonight.”

“You eat like a horse,” joked Rumble, getting a light punch to his shoulder. They opened the office door and exited.

The bright sun made them both wince. They stepped out into the open sky, and despite the relatively warm weather, their coat hairs stood up on end. It was understandable—they could feel the sticky heat behind them warming their rears.

The weather team was working suspiciously hard. And also hard were a number of the stallions, whistling to themselves while looking away from their boss.

“Brag about it,” Scootaloo whispered in Rumble’s ear. “I totally would.”

Rumble laughed. He brushed his wing along her side as she nipped his ear. She spreading her wings and jumped off the cloud, gliding back to Ponyville.
