Growing Up Fast

     The bed sheets were a mess again. Tangled and thrown everywhere, and accompanied by the feeling of perpetual dampness, like they themselves were sweating. Rumble groaned and threw the blob of white fabric sideways, sending half of it off the bed.

                    “Hey! I was using those.”

                    Rumble‘s eyes widened. He wasn’t used to hearing another voice in his bedroom, especially waking up in the morning. With a creak of the bedsprings, he turned sideways, noting his place in the middle of the bed instead of on the side as usual.

                    Cloudchaser grinned at him from her pillow on his left. Her normally well-styled silver mane was a mess, looking like she’d been run through a regular marathon with no cool-down shower for weeks.

                   Rumble’s mind drew a blank, and his mouth almost hung open in shock at the lithe pegasus lying in bed next to him.

                    “Morning, big-guy. You sleep well?” Cloudchaser ran one of her hooves along Rumble’s chest as she spoke, tracing circles against his skin and fur.

                    “I, uh…”

                    “Too tired to talk, huh? I don’t blame you. Me and Flitter were pretty burnt out too, but you definitely worked harder than either of us… I’m surprised you’re awake at all!”

                    Rumble blanched.

                    He remembered, suddenly.

                    The blankets that had remained on the bed were tented at the bottom of his legs. Grinning, Cloudchaser lifted away the mountain of white to reveal a very perky Rumble standing at full attention.

                    “Wow. After last night you’re still not worn out, huh?”

                    Last night…

                    Rumble felt like he might be properly grown up after last night.

                    He and the twins had fucked until sheer exhaustion had overtaken them, and then retired to the bedroom where they’d managed to fuck some more. Thunderlane had sent a note home that he’d be delayed at work, but that he was one hundred percent sure Flitter and Cloudchaser wouldn’t mind looking after Rumble for the night.

                    He was one hundred percent right about that.

                    Rumble felt a hoof against his morning wood as the details flooded back to him.

                    To his surprise, he felt just as big as he had the day before.

                    Which meant Zecora knew how to make a hell of a good potion.

                    “Got time for a quickie before Flitter comes back? She got up early to make breakfast… but there’s something I’d rather eat up here.”

                    Rumble didn’t have to respond – Cloudchaser’s mouth was already hovering over his penis when she finished her sentence, and the moment Rumble tried to speak his words fell away with the sensation of an eager mouth on the head of his cock.

                    “Mhmmm,” Cloudchaser moaned. As Rumble had learned last night, Cloudchaser was much more vocal than her sister; a trait that apparently carried over to fellatio as well. The humming feeling was nice, sending a tingle up his entire shaft and a twinge through his balls as Cloudchaser lowered her mouth and took in a few more inches of cock.

                    Rumble adjusted himself as Cloudchaser began her blowjob in earnest. Where he had been sleeping last night, Rumble had felt too big for his bed – unsurprising, given its intended use for a tiny colt instead of a full grown stallion and his two bedmates. Now, for some reason though, the size felt just a bit more familiar. The pillow he was using didn’t have to press up against the headboard, and his wings didn’t stretch off the sides of the bed when they were flared out.

                    Cloudchaser moaned loudly as she hit the capacity of her mouth, fitting three quarters of Rumble’s shaft inside and tickling the back of her throat.

Hadn’t she only been able to fit half last night?

                    As Cloudchaser’s hair fell over her face, she stared up at Rumble with her eyes wide, batting her eyelashes in a sultry fashion. She paused her head bobbing to lick at the underside of Rumble’s shaft. Rumble felt himself twitch as Cloudchaser stilled her tongue and closed her eyes, steeling herself and pushing her head further forward.

                    Rumble felt Cloudchaser’s lips at the base of his shaft.

                    His wings were stiff from arousal, but the edge of the bed was further away now.

                    And there was a familiar feeling… like a stomach ache, or an itch beneath his skin.

                    What was the opposite of a stretch?

                    Cloudchaser continued her bouncing unabated, now taking the whole of Rumble’s cock into her mouth and slobbering obscenely over the entire length. Her moaning went on, sending shivers along Rumble’s spine and tinges of further excitement through his balls, which Cloudchaser grazed lightly with her hoof.

                    Rumble felt paralyzed. Cloudchaser’s attention was ecstatic, but the rest of him felt like he wanted to throw up again – or to get up, to run to the bathroom and look into the mirror, to see if what he was feeling was real-

                    Cloudchaser wasn’t bobbing her head anymore – she was moving it up and down in short several inch movements. Her lips were stronger now, pressed against Rumble’ shaft instead of the insides of her cheeks.

                    And amidst the surging in his stomach and the feeling of his body compressing upon itself, Rumble felt a strong twitch, and a reminder at the back of his head.

                    “Cloudchaser, I think I’m-“

                    His warning was devoid of depth and husky tone. He sounded like a kid asking for a cookie out of the jar.

                    “Mhm,” Cloudchaser murmured over the cock in her mouth. She didn’t open her eyes or look up, but continued her sucking.

                    An instant later, Rumble came.

                    One, two, three squirts. Cloudchaser swallowed all three of them, and pulled her head up with an ‘ah’.

                    Rumble stared up at her. The world at once seemed much bigger again.

                    “Oh… wow. Look at you.”

                    The words of someone not sure entirely what to say.

                    “Am I…?” Rumble began to ask, but found the answer in his own voice. It sounded just like the colt who had begged Zecora for her potion in the forest.

                    “Huh. You, uh… you look a little… younger, Rumble.”

                    “I do?” Rumble asked, almost with tears in his eyes. He had been so sure. Zecora’s potion had worked, and he’d endured stomach aches and shifting, and then been rewarded with…

                    “Yeah. You look like… wow, you do not look like I remember from last night. Ohmigosh, last night…”

                    Rumble would have blushed if he wasn’t so distraught.

                    Cloudchaser was in a bit of a state herself, torn between wanting to comfort the obviously distressed colt lying in front of her, and the realization that she’d just spent an entire night in what essentially amounted to roundabout foal-fiddling. Even the memory sent a twitch in between her legs though… well, Rumble had been an adult then, so maybe it was all good.

                    Of course, he was a colt now, and Cloudchaser could taste his cum on the back of her throat.

   "You were... when we showed up you were in bed, and you were normal size... but then you... and we..." Cloudchaser was talking mostly to herself, trying to puzzle out how the visit had gone from a check up to a three pony rutting in the living room.

   "I guess... I remember feeling your wing, and it was so well-formed and buff, and you looked just a little bit bigger than I remembered. And then you, uh... looked a lot bigger."

   Cloudchaser hazarded a glance in Rrumble's direction.

  "I guss we just got a little... carried away."

                    Rumble sniffed in an attempt to hold back his despondence.

                    “Oh, jeez… listen, uh, little guy–“

                    “Don’t call me little!” Rumble huffed, and turned sideways. He was barely big enough to reach halfway down the bed now.

                    “-Sorry. Listen, uh, Rumble… I dunno what happened last night really. I mean, I know what happened, but I don’t know why you, uh… and Flitter and I…”

                    The words weren’t helping. If Rumble had clarity to spread on the situation, he was withholding it in interest of his own depression. Which, in his mind, he had every right for. So close, he had been so close to being a proper grown up, and now it was all gone after one of the best nights of his life that he’d never have back…

                    “Look. That’s not important. I uh… I can’t see that happening again while you’re so, uh… I mean, I’m not sure what to say. You’re just a kid, Rumble! We shouldn’t have been doing stuff like that with you in the first place!”

                    “But I’m not a kid!” Rumble protested, turning back to face Cloudchaser. “Or at least, I wasn’t then… and I’m not supposed to be now either.”

                    “Well… okay, fair enough to your first point. I don’t know about that second part though. I mean… you look like a kid to me.”

                    Rumble’s eyes teared up, and Cloudchaser tried to form a different counterpoint.

                    “That’s not a bad thing! I mean, you’re cute as a kid. You’re adorable!”

                    “I am?” Rumble asked, not sure if he should wear the description like a badge of shame or triumph. He crinkled his eyes as Cloudchaser rubbed his head with her hoof.

                    “Yeah, you’re the best! And, uh… I mean, when you grow up, if last night is any evidence…” Cloudchaser coughed loudly before continuing. “I’m sure you’ll have plenty of mares wanting a piece of your business.”

                    Rumble looked up hopefully at Cloudchaser, asking without words if she thought she was telling the truth.

                    “Just, uh… not us. Right now.”

                    The two sat in silence for a moment. Cloudchaser tried to keep herself as composed as possible, but still found herself reminded that as much as she protested, she had just swallowed a spray of little Rumble’s cum only minutes ago.

                    Rumble wasn’t sure what to think. He’d had everything he wanted, and then had it pulled away from him. Was there a positive spin on that?

                    Well, maybe.

                    Rumble had gotten a preview of what was to come. More correctly, he had gotten a preview of one very particular aspect of adulthood – and he’d loved it, no question. But that was only part of being grown up. He’d been physically bigger, and he’d done things that only older ponies did (and a great many of things none of them did)… but he hadn’t done everything. He’d grown, but he hadn’t really grown up.

                    Maybe that was the point. Zecora wasn’t the type to be straightforward… and she’d made that potion with so little hesitation, Rumble had guessed there was some kind of catch.

                    Was it a catch, really?

                    Rumble had been ‘grown up’ for a little bit… and he’d realized that even in that grown up situation, though he’d adapted relatively quickly, he’d still felt lost a great deal of the time. He’d found his way by instinct – and maybe that was the whole key to it. Grown-ups weren’t any different from kids… they were just ponies who’d gotten used to thinking differently. And if Rumble had convinced himself he was different from his classmates, whether through instinct or distaste for stupid games – he wasn’t meant to be ‘older’ than them. He was just more ready for the day that he was grown up.

                    That meant waiting. But, at least in a concrete sense, Rumble was fairly certain there wasn’t really a magic potion to make him grow up.

                    He had grown, certainly… and maybe he’d grown up just a little bit.

                    “Are you guys ready for breakfast? I hope I didn’t make too much.”

                    Flitter opened the door with a tray of pancakes and orange juice, floating them over to the bedside table before turning to the bed’s occupants.

                    “Oh, my…” she said upon seeing the de-grown Rumble and Cloudchaser beside him.

                    “Yeah… uh, sis… it looks like things last night might have been a little… weird.”

                    Flitter blinked and looked at her sister before quietly looking down at the floor.

                    “Cloudchaser, you have a little something, on your, uh…”

                    Cloudchaser raised a hoof to the side of her mouth, her eyes wide in embarrassment. Her hoof dabbed just a tiny bit of wetness. When she pulled it away to examine it, she found a speck of white on her hoof.

                    All three ponies sat in silence for a minute.

                    With a sigh, Cloudchaser wiped her hoof on the remaining blankets.

                    “I told Rumble, uh… that whatever happened last night, I don’t have a problem keeping it to myself, but that it probably won’t happen again anytime soon. Which, I think he gets, right?”

                    Rumble sighed too, but nodded otherwise silently.

                    As much as he didn’t want to, he ‘got’ it.

                    “Stellar. It’s nothing personal, Rumble. Just, uh… maybe when you’re grown up some day, okay?”

                    “Um.”

                    Flitter drew attention to herself in as non-conspiratory a fashion as possible. Both Rumble and Cloudchaser turned, finding the pegasus with one of her forelegs behind her back.

                    “On my way downstairs to make breakfast, I, uh… found this rolled out from under the bed.”

                    With a clink, Flitter set the green bubbling vial down on the bedside table next to the pancakes.

                    Rumble and Cloudchaser stared at it. The liquid inside burbled and glowed in a semi-threatening fashion.

                    “Rumble, is that…” Cloudchaser asked, not sure particularly what to call her speculations on the nearby concoction.

                    Rumble couldn’t bring himself to lie.

                    “…yeah.”

                    All three ponies paused for a moment further.

                    “Well…” Cloudchaser said.

                    “Um…” Flitter accompanied, both of them staring into space at nothing in particular.

                    Rumble hazarded a glance towards both of them before reaching out and grasping the beaker in both hooves.

When you’re grown up some day…

                    “Mind if I take you up on that offer sooner rather than later?” Rumble asked.

                    The twins grinned at him.
