My Anonconda Don't Want None...

"Anon! Anon! Hey, Anon!" A kitten-sized blur flitted quickly past his head. It circled around once, twice, three times, before it skidded to a stop and resolved into Rainbow Dash. "Hey, Anon! Are you even listening to me?"

"Well, I am now." He shook his head and blinked a few times. Long as he'd been living in Equestria, it was impossible to get used to all of the tiny ponies running — or, often as not, flying — circles around him. He'd never felt particularly big and slow before shacking up with Rainbow Dash, but now that he was committed to the little pegasus, he rarely felt like much else. "What is it?"

"Not telling yet, champ!" she squeaked, in her itty bitty pony voice. She flitted over to his chest and looked up at him expectantly, eyes wide as they could get. "Carry me?"

Anon sighed and put his arms up, nestling Dash between them and his chest. She wiggled her rear in and rustled her wings a couple times to get comfortable, acting for all the world like she deserved to be carried. Anon shook his head and sighed again. She was pretty fluffy and adorable, and at least ponies didn't shed. "Where to?"

"Bedroom." She grinned. "We're gonna fuck."

"You sure?" No comment on how forward that was. Anon shuffled slowly up to the bedroom of his human-sized house, where he slept in human-sized sheets on a human-sized mattress. Most things in Equestria were much too small for him, but at least his house was built to scale. "We've talked about this, Dash. There's a little problem with trying to—"

"Hey, are you doubting me?" Rainbow Dash rustled herself in his arms, clearly offended. "I got it all under control. You just do the walking and I'll let you know when it's time for the talking."

No further comment, then. A quiet blush spread across his face as a warm, slick wetness bled through his shirt and smeared against his skin. Anon had his doubts that anything much like sex would be happening tonight, seeing as his dick could wrestle Dash to the floor with no added effort on his part, but Dash was clearly in the mood right now. The least he could do was entertain whatever crazy plan she'd cooked up this time. No matter what it was, it couldn't possibly be worse than the time she'd asked Twilight to shrink his cock down to tiny pony scale.

He opened the bedroom door and turned on the lamp in the corner — bright enough to see by, dim enough to hold a mood. "Alright, we're here. What's the surprise?"

"This!" Dash scampered out of his arms and zipped over to a large, blue-glass bottle on the nightstand, just a little taller than she was. She thumped the cork on top and stared at him expectantly. "You gonna help me with this or not?"

"Not until I know what 'this' is." He picked up the bottle, Dash and all, and studied it for any sort of identifying labels. A sticker on the bottom featured, in big, blocky letters, a rather ominous Drink Me. He squinted extra hard at that one. Shades of Alice in Wonderland. "How did you even get this in here?"

"C'mon, do you have to know?" Dash flew out of his grasp again and crossed her forelegs petulantly. "I got it from Zecora — you know Zecora, right? She's on the level. It's not like I'd ask her for anything too dangerous."

Anon heaved a sigh. Rule number one of being with Dash was no talking about fight club. Rule two was never arguing with Rainbow Dash when she wanted something. "Alright, alright, but if something goes wrong, I'm not explaining this to poison control." He dug a little fingernal into the cork and managed to pop it out with a couple tugs. "There. Got i—" His nose wrinkled a bit as fumes radiated out from the bottle's open neck. Holy shit, that smelled foul. Like a week-old cabbage deep-throating a rotten banana. He tilted his head at Dash. "You know this is going to kill you."

"Hey, shut up! I know what I'm doing." She dove back into his arms and pointed at her open mouth. "Gimme."

"I want it clear that I was against this from the start." Still, he tipped the bottle into Dash's waiting maw. It would have been kind of cute, even, like feeding a kitten milk from a bottle, if he could only forget he was swaddling a horny pegasus with a hunger for cock.

After a few swallows, Dash pushed the bottle away and gasped for breath. "Blech! Tastes like a week-old cabbage deep-throating a rotten banana."

"So..." Anon re-corked the bottle and set it back on the nightstand. Looked about two-thirds full. Hopefully that would be enough for a medical expert to figure out an antidote. "Mind telling me what that was, exactly?"

"Well, if you really want to, it was — hup!" Rainbow Dash hiccuped, and her body thrummed bigger in his arms. She dropped a little as he rebalanced for the extra weight. "It was — hup!" Creaking, cracking, bony sounds, and rubbery stretching noises. The little pegasus in his arms wasn't so much the size of a kitten now as a full-grown cat. "Growth — hup! — potion."

Aha! Growth potion! So that was the plan this time. Since she couldn't shrink him, or his dick, down to a pony-manageable size, Dash had decided to grow to match him instead. That was... surprisingly smart of her, honestly. And really hot. Finally, they could both be the right size for a proper fuck.

She leapt onto the bed, finally heavy enough to bounce the springs. The mattress sank slowly beneath her as her body thrummed bigger in tiny, fitful spurts. "Well? What're you waiting for?"

"Fucking nothing, that's what!" His clothes came off in a flash and his dick stood erect in ten seconds hard. "Let's go!"

Dash crawled up onto his stomach as he laid his naked body on the bed. She wasn't quite the size of an honest-to-God pony just yet — probably closer to a smallish dog — but the end of her growth seemed nowhere in sight. It was the strangest thing, feeling the soft, furry weight on his chest get five, eight, ten pounds heavier in a single leap. Her racing heart seemed to pump deeper and faster with every passing moment, and new inches of Dash's body stretched over him with every spurt.

But strange as it was, his painfully-erect rod certainly wasn't complaining. Neither was Dash, if the little drops of pegasus-juice pattering on his stomach were any sign. He reached a hand behind her and gave her flank a little squeeze, eyes widening as muscle and fat strained against his grip. He pulled his hand an inch away and Dash gasped as her swelling ass grew again to meet his fingers, expanding until it started to press them even further back.

"You don't know how long I've been waiting for this," Dash panted. She groaned as particularly strong growth spurt ran through her body and her head crept noticeably higher. "You as ready as I am?"

Anon had no words left, and hardly any breath with a growing Dash lying on his chest, but gave her a clear nod of approval. She nodded back and positioned herself carefully over his awaiting length. Her warm, pulsating lips ran slowly up and down his shaft, kissing and caressing it until it was slick enough for the main event. Fuck! He had to bite his lip and strain to not cum right then and there. He didn't have much experience fucking ponies, but Dash's pussy against him, sliding ever so slightly as Dash herself grew larger, was better than anything he'd ever felt. It beat the hell out of masturbating, anyway. That much was certain.

"Ah!" They gasped together as Dash finally impaled herself on his dick, her pussy big enough now to take him at a tight squeeze. The walls wrapped around his cock like a too-small glove, the gentle throb of Dash's own heartbeat sending periodic jolts up Anon's spine. "Fuck! Too much!" Dash cried, just as another growth spurt her. She shot up to an even four feet, giving her plenty of extra room for him. She sighed and moaned a long, deep moan, her pussy clamped down to give him a proper love-squeeze. "Theeeere we go." She groaned as she rose up and sank down. Up and down again she pumped, hips colliding just a tiny bit harder than before. "Loving — unf — the weather up here! Is this what it's always like for you?"

Up and down once more, but this time her head fell nowhere near as low. Far from the cute, kitten-sized Rainbow Dash who'd originally stood shorter than his own cock, the new and improved Dash almost seemed to tower over him. Their hips collided with avalanche force. "Dash!" Anon cried out, the impact finally cutting through the haze of pleasure. "You're still growing!"

"I know!" Dash shouted gleefully. "It's the best, right? Biggest and fastest pony in Equestria, and she's all yours." She grinned down at him as she surged up another half-inch and her still-growing cunt pulsed against his cock. "Or more like you're all mine. Same — fuck yes! — same difference, y'know?"

Anon didn't entirely like the sound of that, but Dash's powerful, oven-hot pussy rolling over his shaft shorted out any conscious objections. Dash was big now, and a big Dash was a sexy Dash. All he could do was pray to Celestia that Dash didn't get too big — not that she was liable to answer. The increasing expanse of his lower half smothered by Dash's warm, pillowy flank paid testament to that.

"Mmm, Yeah! Harder!" Her spacious honeypot was still milking his dick as hard as ever, but he could only fill less and less of her as Dash's growth continued. Her hips slammed down on him wetly and slowly rose up for another, even heavier descent. Anon tried a weak, half-hearted thrust in a desperate attempt to sate her, but when his met hers, her bulldozer of an ass pressed him into the mattress like he'd never even tried. It was like trying to fuck a truck. A giant, horny, technicolor truck. He was going to be feeling that one in the morning.

"C'mon, Anon, I thought you were bigger than that!"

"Not if you keep growing!" he grunted. Thankfully, it was just about then that Dash's growth seemed to peter out, but that was too big, too late. From the mountain of pony sitting on him — her oppressive weight cushioned only by a layer of soft, fatty flank — it looked like she was just taller than he was. Sitting down. "Dash..." he started. "You're—"

"Huge, I know!" Dash cried. "I'm big pony on the playground now, and I love it!" She looked down to her crotch, still hilted on him, her cunt still rolling and undulating against his dick. "But — and not trying to bruise your ego here — you're a little too small for me now. You know the feeling, right?" Her pussy released him with a reluctant schlorp, the mattress creaking in protest as she turned around and presented her dripping slit. "Mind bringing me to the finish line?"

Anon gulped as the overwhelming musky odor of Dash's arousal washed over him, bathing his face in a thick heat. Streams of her own lubricant trickled down from her puffy pink cunny, big enough to swallow any dick — or even an arm! "I, uh, well..." he stammered as she wiggled her flank in his face, sending droplets of Dash-cum flying in every direction. He wasn't altogether sure of the wisdom of letting Dash's heavy hind-quarters anywhere near his fragile head. "I don't know, maybe we should—"

"Not interested?" Dash snorted. "Then how 'bout I sweeten the deal?"

She leaned down and wrapped her lips around his cock, enveloping it in her warm, moist breath as her titan-sized tongue wrapped around his shaft. At that size, his dick hardly even counted as a decent snack to her, but his second brain had no way of telling the difference. An inarticulate moan of pleasure escaped his lips, followed up by a more coherent "Fuck yes."

Rainbow Dash seemed to take that as approval, and her sky-blue ass fell on him before he could clarify. His world quickly turned to sopping horse cunt, half-drowning him in Dash's salty-sweet arousal before his brain could order his mouth to start working. His hands wrapped themselves around her cheeks, squeezing the paradoxical mix of rippling muscle and jiggling pony fat to get a grip as he started eating her out. He'd never done so before with much enthusiasm, but he was doing so now with all possible gusto — half from sheer arousal and half because he could sense his own dwindling oxygen supply. If Dash didn't get off quick, it was disturbingly possible that he'd wind up smothered under her ass. Death by plot — what a way to go.

And as he licked and suckled at her enormous, throbbing clit, Dash stepped up her own efforts on his merely average cock. Her tongue danced between fondling his balls and wrestling with his shaft, a gentle sucking in the background as the head touched just barely against her throat. It was simply too much for him. Anon had taken all he could stand, and he couldn't stand no more. "Uungh!" It would have been a scream, if not muffled by Dash's all-encompassing flank. The orgasm was mind-numbing, balls pumping out all they could spare down the black hole of Dash's cavernous throat. All higher thought was swiftly obliterated by the release, but he remained just barely functional enough to continue lapping at Dash's slit, gulping down as much of her juices as he could manage and massaging her inner walls with his tongue.

"Ah, oh, there! Yes! Yes! Oh, Celestia, yes!" Dash's own climax was explosive, to say the least. The walls contracted tightly and let out a positive flood of marecum, displacing everything that might have been air with her own essence. If Anon hadn't been soaked in Dash's fluids before that, he definitely was now. Dash rolled off him with a contented sigh, slipping right over the bed's edge and crashing straight to the floor. It was just as well, Anon supposed. The mattress would probably need new springs after this one.

"Good for you too?" Dash panted, picking herself slowly off the ground. Even sitting down, she could look down on him easily. "'Cause that was pretty good for me."

"Yeah," Anon panted, savoring the fresh oxygen now that Dash was off him. "Pretty good." And it had been. Not quite what he'd been expecting, but it was a hell of a lay for his first real fuck with Dash. "Pretty damn good."

Now that he had a moment to stop and think, though, it was time to figure out the next step. Big Dash was hot as hell, but another round of sex with a pony that big would kill him. "Hey, Dash..."  Maybe if he could get her back down to a more reasonable size. Just a little, down to a manageable four feet or so, instead of a towering six. "That potion ever going to wear off?"

"Beats me." Dash shrugged. She laughed and stood up to her full height. "But so what if it doesn't? I like being large and in charge."

"Uh, well..." Anon's heart skipped a beat. Well, that didn't sound good. Six-foot-tall Dash was an amazon to him and a bona fide giant to other ponies. It was bad enough if she stayed that way, and even worse if she got to enjoy it too much. She needed to shrink, if even just a little bit, and he had to convince her that was a good idea. That was possible, probably. He just had to broach the subject carefully. "You know you can't stay that size forever, right?"

"Yeah... I guess so. Can't stay this size forever. I'll talk to Zecora in the morning. We'll see if she can whip something up for me."

Dash heaved a sigh of disappointment and Anon heaved a sigh of relief. She didn't look totally convinced, but so long as she — wait. He paused. Was that a smile?

Was that a smile?

"In the meantime, though," Dash said, breaking out into a full-on grin. "I'm feeling kinda thirsty right now." A massive hoof reached down toward the blue bottle on the nightstand, still two-thirds full with concentrated growth potion. The cork popped off with barely any effort, and Dash raised the bottle slowly to her waiting lips. "Think I could use another drink..."
