Get Big On 'em (or, 'Rumble's Tumbles in the Hay')

Rumble was in his room, going over his list, which had by now grown to three pages (double-sided, and counting), when he heard a knock at the door. Not expecting company, and knowing his mom didn't have her hoof-care product sales meeting until next week, Rumble went downstairs a little uncertain, but mostly just expecting somepony lost and looking for directions.

What he got was the pair of Lyra and Bonbon standing on his front step. Lyra was looking away and shuffling her hooves on the ground awkwardly, while Bonbon was staring at him with a staunch look on her face, like she was being held at horn-point to recite a speech.

Rumble wasn't sure what to say. Best to start with the usual. "Uh, hello. How can I—"

"Is there somepony who lives here who..." Bonbon looked back at Lyra, then
down at a small list on paper she was carrying in her hoof. "...'is totally
ripped and kind of looks like that guy from Superpone after his transformation sequence'?" Bonbon crinkled her nose and squinted harder at the piece of paper. "Oh. And... 'he's totally a pegasus and he looks like he has a... the size of...'... oh. Ahem. Anyways. Is he home?"

Lyra whispered behind Bonbon, "You got this!"

"Shut up!" Bonbon whispered back, and swatted at Lyra with her hoof, bonking her on the head.

"Oh." Rumble took a moment to assess the situation. He had to think fast. But there were two ponies waiting for somepony else here, and all he had to do was be that somepony else. Maybe the potion was what had gotten them here in the first place. "Yeah, I think you mean my brother. He's uh, upstairs. I'll go get him."

Rumble took off as fast as he could upstairs, leaving a smiling Bonbon and Lyra behind.

"See? I told you he lived here."

"What if he comes down and it's a different guy?"

"Shut up!"

When Rumble got to his room, he checked the bottle he'd gotten from Flim and Flam to see how much was left. Over two-thirds, and he'd been sampling it every other night just to check the effects and jerk off while thinking about what his next escapade might lead to. This was definitely an occasion that called for a dip into the stash—and Rumble took double, just like he'd planned before. It was time to see what a little extra juice could do.

Still totally unlike the potion from Zecora, this elixir began the transformation almost instantly, and before he could put the bottle down, Rumble felt surges of muscle and growth going through his body. His wings enlarged on his back, his cock grew and dangled between his legs, hanging so low when soft it almost touched the floor. He could feel himself swelling, his balls getting bigger, everything about him becoming fiercer, larger, and more virile. The smell of pony-sex wafted off in a mix of pheromones, and he smirked to himself in the mirror before heading back downstairs, leaving the bottle stoppered and safely on its place on his bedside table.

"Somepony was looking for me?" Rumble said as he walked down the stairs to the front entrance. Sure enough, Lyra lit up at the sight of him, and then tried to hide her enthusiasm behind Bonbon's back. Bonbon seemed still more scrutinizing.

"I think so. You fit the description. This is the awkward part." Bonbon steadied herself and took a deep breath, closing her eyes as she inhaled and opening them with the exhale. "Okay. No pressure. Would you—"

"Doyouwannacomebacktoourplaceandhavesomefun?" Lyra blurted out, unable to contain her enthusiasm a second longer.

Rumble took a second to pull the words apart, but once he got the shake of the sentence, he couldn't help but grin. "Fun?" he asked. "What kind of fun did you have in mind?"

"Oh brother," Bonbon whispered to herself. "What have I gotten into?"

"So here's the deal," Bonbon said, checking the bedroom door locks and ensuring the blinds were closed. "Today's not a safe day for me, so before you cum, you gotta at least pull out and shoot it on my butt or something." Bonbon shook her rump for good measure, waggling her luscious, cream-white cheeks in Rumble's direction, and being rewarded with an eager-sounding groan. "Lyra's on that new magic pill or whatever—"

"I got the one that tastes like donuts!" Lyra interjected, smirking broadly.

"—right. So, you can cum in her all you want. Although, between you and me, what she really likes is when you pull out right before you're about to shoot, and give her a big sticky load all over her face and mane—"

"Bon!" Lyra slapped Bonbon's hoof. Her cheeks were flushed red, and her mouth was narrowed. "Cut it out!"

"What? It's true."

Lyra shook her head, then turned to Rumble, giving him a big, filly-like grin. "Don't listen to her. I love getting a load inside my pussy. Mmhm-mmm. Fill me up, Daddy."

"Shut up! You just want him to finish in you cause that means you win."

Lyra did her best to look aghast, and put a hoof to her chest to complete the image. "What? I would never! This isn't about some silly competition, anyway. It's about three consenting, adult ponies..."

Rumble cleared his throat, masking the nervousness in the sheer baritone of his aged-up voice.

"...who are here to spend time together and make each other feel good." Lyra lied back on the bed and spread her legs, showing off her already damp pussy to Bonbon and Rumble. "Now, who wants to get their face wet first?"

Bonbon rolled her eyes. "First you complain about needing a dick, and then you wanna get your pussy eaten? You are completely ridiculous."

"I just wanted a little warm-up before we started."

"How about this," Rumble said. He stood up on the bed over Lyra, then effortlessly, almost like she wasn't there at all, picked up the green pony and held her over his head.

"Woah!" Lyra shouted.

Rumble spun her about once before plunking her at the end of the bed. He took his place where she had been lying, sitting himself down and putting a hoof against his half-hard cock, which even without a full erection, still put Bluey in the corner to shame and then some.

Lyra eyed his cock like the piece of meat she'd be hungry for. She stuck out her tongue and licked her lips, leaving a little bit of drool hanging from her chin.

"How about you warm up this—" Rumble gestured to his dick, which he held out with the tip towards Lyra's face. "—and get on, and while you're going to town, your girlfriend can lick you out." Rumble grinned as Bonbon's face twisted into the same. "That way you'll be nice and satisfied before she gets a turn."

"But I wanted to win—eep!" Lyra squealed as Rumble lifted her again, planting her down further up the bed, with her face directly in front of his cock. Despite herself, she found her tongue lolling out, unable to stare anywhere other than the tree-trunk think shaft stretching out in front of her face. "Ooh. That looks tasty." She gave the pole in question a lick, and giggled, apparently finding it to her liking. "Mmhm. Salty." She licked up Rumble's shaft again, starting at the base just above his balls (which she lapped at softly as well), before slowly tracing up the length of his dick, all the way to the head, which she finished with a little kiss, and another giggle.

"Are you gonna suck on that thing or do I have to do it?" Bonbon asked, tapping her hoof impatiently on the bedspread.

"Oh come on, I was just enjoying myself." Lyra lapped at Rumble's head again, and was rewarded with a twitch of his whole cock, which prompted another giggle. "Ooh! I think it likes me."

Seemingly satisfied with her introduction to her new, gargantuan friend, Lyra finally took Rumble's head into her mouth, albeit with some difficulty. She let her spit dribble out onto his head and shaft, and gave him a few gulps up and down, only about halfway down the length of his cock, but still more than enough to start him hardening in her mouth. Before Rumble knew it, his cock was a mess of spit and Lyra's mouth friction, warming him up and getting him as hard as he'd been in Spitfire and Dash a few nights ago. Maybe harder.

When Lyra was happy with her hoof-and-mouth-work, she popped off Rumble's cock with a slutty-sounding ahhhh, and wiped her hoof over her mouth, spreading the drips of drool across her chin and lips. "Yep," she said. "Tastes great. Heehee!"

"Just hurry and start getting pounded," Bonbon said, pushing Lyra's head downward and trying to move her body into place above Ace's now-throbbing member.

"Oh, fine! Stop rushing me." Lyra batted Bonbon's hooves away and propped herself up over Ace's body, staring down at his obscenely large tool and wondering if she'd bitten off more than she could chew. The descent was a struggle—Bluey had been amateur-size compared to this—but after a determined look, and a series of soft whimpers that made Rumble's cock twitch inside her, Lyra managed to make her way two-thirds down Rumble's cock. The remainder was just outside her cunt, filling her up all the way, spreading her lips wide.

"Holy buck," she said, shaking her head and sending a few drops of sweat flying. "I don't think I can take anymore. This thing is bucking huge."

"I thought you wanted a rutting, hun," Bonbon said, smirking. "Isn't that what you said?"

"A rutting?" Rumble asked, chiming in and getting another squeal from Lyra as his cock twitched once more. "Why didn't somepony say so?"

Lyra was just as light to lift a second time, only now she was lodged on his cock besides. It made the maneuvering a little more awkward, but Rumble felt a power he hadn't known in all his life, and it made rearranging everything easy, until Lyra was propped up on all fours and he was behind her, still not-quite buried inside. Rumble gestured down at Lyra's pussy, and Bonbon nodded, smiled, and lay down on the bed, sliding herself under Lyra's stomach and positioning her mouth just next to Lyra's dripping wet slit.

"Ready?" Rumble said, placing a hoof on either side of Lyra's svelte backside.

"Ready," Bonbon said, and nodded with a grin.

"Hey, wait a minute. I never agreed to—oh shit!"

Bonbon's tongue had gone into action the moment Rumble had slammed himself home, thrusting powerfully forward and burying the last few inches of his monster in Lyra's sopping pussy. A trickle of her juices ran down her leg and onto the bed the second she felt Rumble's cock-head slam inside her, and she let out a long, high-pitched moan that sounded like she was on the verge of a religious experience.

"Oh shit," Bonbon said, taking just a second away from her tonguing to clue Rumble in. "She's gonna cum soon!" Bonbon dove back to Lyra's pussy, licking circles around her clit and occasionally darting down to get a taste of Rumble's slick shaft as it slid in and out of Lyra's cunt.

"Ahhh, ahhh, ahhh!" Lyra lost words, lost language as her voice devolved into a series of desperate sounding screams, wrenching the sound and breath out of her body as she seized and began to shake and shiver, her pussy clenching tight on Rumble's cock. She rolled her head back and from side to side, tossing her mane wildly, mumbling incoherently as her pussy twitched the final time, settling her orgasm back on Bonbon's gently lapping tongue.

"See?" Bonbon said. "She's quick."

"Shut up—ahhh!" Lyra's sentence was cut off as Rumble started thrusting in her again, shaking the bed and Lyra besides. She reached back a hoof and Rumble took it, hanging on to her for balance and pulling him back against her each time he slammed his cock inside. "Unh, unh... holy Celestia this is good, this is just what I needed..." Lyra let out a throaty groan as Rumble fucked her, reaching back her other hoof to spread herself even wider for his girth, with Bonbon still licking diligently at her love-button. "Shit, I think you're gonna make me cum again." Lyra spread herself even further, began rocking herself back to get as much of Rumble inside her as she could with every thrust. "Shit, shit, shit, here it comes, I'm cumming—" Lyra tilt her head forward and bit down on the blankets, the last word blurring into a howl as her pussy quivered again, squeezing Rumble's cock like it was the last source of moisture in Equestria, aching for a hot coating of sticky semen.

But Rumble wasn't done yet. And Bonbon still had yet to get her turn.

"Do you want a spin?" Rumble asked, eyeing Bonbon and nodding to his cock, which was still halfway buried inside Lyra, throbbing maybe-even a little larger in anticipation of the load Rumble had yet to blow.

Bonbon extricated herself from below Lyra's legs, and nodded. "Uh-huh. She's not the only one who gets a turn." Bonbon's grin turned into a hungry leer as she turned and presented herself, peering up with her head turned and staring into Rumble's eyes. "Come on. Give it to me hard."

"With pleasure." Rumble pulled his cock out of Lyra's soaking-wet slit with a slurping noise, and was over to Bonbon before the first drip of filly-juice had left his cock-head. Lining it up, the same as the first, this time against a coat of cream-white and blue-pink swirls. Bonbon's lips parted to greet him, letting him slide the first few inches inside smoothly, Bonbon's gasps following as she took in the full size of the thing that was penetrating her.

"Oh my gosh," she said, steadying herself on the bed and looking back at Rumble to see what she was experiencing. "You weren't kidding, Lyra. That thing is huge."

"Isn't it?" Lyra asked. She sighed contentedly, sprawled out on the end of the bed, and began to play absentmindedly with her pussy, stroking it in circles with her hoof and moaning softly as she watched her partner get opened up by the biggest stallion-cock she'd ever seen. Even bigger than the ones in the catalogs.

"You want it hard too?" Rumble asked, shoving himself the last few inches into Bonbon's cunt. "You want me to rut you?"

"Buck yes," Bonbon said, raising her squishy butt up more and jiggling it in Rumble's face. "Rail me. Now."

Rumble, never one to disappoint a filly, did as he was asked. Bonbon's butt bounced against him like cushioning as he thrust in hard, making a smacking noise and then drawing his cock out again, teasing Bonbon with the head in little one-inch bursts.

"Come on," Bonbon hissed through her teeth, staring at Rumble's cock between her legs. "Don't tease me. Rut me. Please."

Apparently this was the correct response. Rumble grinned and put a hoof on either of Bonbon's luscious cheeks, squeezing them together, before he began pounding her, fast, hard, so much the pictures on the night-stand started to shake and jostle towards the floor.

Just as one of the pictures was about to slip off the table, Lyra caught it with a flash of green magic. Her horn glowed as she hovered the other pictures into a small pile next to the bed, resting safely on the carpet, as long as nopony aimed their load in that direction.

Speaking of which...

"You want me to cum on your ass?" Rumble asked, slamming Bonbon so hard her tiny moans were interrupted every other thrust as her body jostled against Rumble's thick, masculine frame. The set of cheeks in front of him was definitely a sight waiting to be painted in cream, to match the colour, to dribble slowly between her cheeks...

"No way," Bonbon managed, finding her breath and the space to speak inbetween thrusts. "When you're... gonna cum... unh!... you've gotta... holy buck... pull out and... unh... do it on Lyra's... face." Bonbon grinned over her back at Rumble before returning herself to face-down, ass-up position. "She... unh... loves it..."

"Oh, come on, you're spoiling me!" Lyra smiled and shuffled herself on the bed so she was closer to the action, now with a close-up view of the sight of Rumble's cock sliding in and out of her partner's warm, lubed-up slit. Lyra licked her lips as she watched the veiny shaft bury itself, then slide back out, the head just peeking as it parted Bonbon's lips.

"Oh buck, I'm gonna cum," Bonbon shouted, bracing her hooves on the bed. "I'm gonna cum so hard..."

Sure enough, Bonbon started clenching like she was possessed, suddenly wringing Rumble's cock for every drop of hot, sticky cum that had been stored up in his overgrown balls.

"Me... too..." Rumble managed, grunting furiously as he plowed Bonbon's ass at full speed. He waited as long as possible, letting Bonbon's cunt squeeze him, squeeze him tighter, listening to Lyra and Bonbon both moaning as he pulled his cock out, pointed it squarely at Lyra's face, and began to jerk it with both hooves. "Here it comes..."

Lyra opened her mouth wide and rubbed her pussy frantically as Rumble's load hit her face. The splash was so powerful, she staggered back a little, going from a clean, albeit sweaty face, to suddenly being coated in jizz, like she'd put on a face mask that was three times thicker than normal.

That was just the first blast. The second made a thick 'splash' sound as it sprayed against her chest, jerking up to hit her chin and inside her mouth at the last minute. Her mouth was overfull already, rivers running down her lips and staining her coat a bright white.

Rumble groaned and squeezed his cock with both hooves. Bonbon, on the tale end of her orgasm, spun herself around and started licking and squeezing Rumble's balls, coaxing the last few spurts of cum out of them, the final of which dribbled down the head of Rumble's cock and left a thin trail between it and the bedsheets.

All three ponies, when the final spurt of cum had been fired, collapsed onto the bed. Bonbon and Rumble sweaty, Lyra the same, but also looking like she'd gone bobbing for apples in a barrel of homogenized cream.

"That," Lyra said, "is what I meant by a 'rutting'." She sighed and flopped over on the bed, unconcerned with the dribbles of cum soaking into the blankets and spilling onto the nearby carpet.

Lying back on the bed, his hooves behind his head, Rumble smirked.

So many mares, and so little time... before he knew it, he'd be paying another visit to Flim and Flam. Hopefully somewhere more hospitable than the Everfree this time, mind...
