120 Nights of Pony

"That was adorable."

"Fuck you."

"Perhaps later. Especially now that Applejack has taught you how to slow down."

I sigh, as I plot my next move...surely Pinkie knows some freaky stuff?

"Hi hey hello welcome to Sugarcube Corner--oh, hey Nonny!"

I stare at her for a moment. I blink. "How," I ask, "did you know my--"

"I know everypony's name, silly. Besides, you came down to Ponyville last week! You still haven't had your welcome party~!"

"But I--"

She ducks below the counter and pops up behind me, nudging my shoulder. "Got stuck in a timeloop, and got bizzaaay~! I know all about it," she says with a wink. "Don't you worry, Nonny. My friends don't call me Kinky Pie...but I know you do!"

"Heheh, yeah," I mumble. You know, nobody ever talks about it, but Pinkie's shenanigans are kind of scary.

"So, you ready to put some cream in the Pie?" Pinkie says, bouncing around me with wild abandon. "C'mon! Let's head up to my room! My bed's super comfy. I know you like doing it where ponies can see you, but I don't wanna freak out the neighbors." She talks nonstop as we head upstairs, her perky pink posterior waving in my face the whole time.

In the upper floor, there's three bedrooms. Two of them are closed off by regular-ass wooden doors. The third is bright neon pink, covered in rainbow glitter, and has "PINKIE" spelled out with cut-out bits of construction paper.

"Guess which one's mine. Go on. Guess."

"...that one?"

She gasps! "How did you know? You must have Pinkie Sense too!" She zips into her room, leaving the door open. It's like a sugar-coated rainbow explosion went off in there.

I walk through, closing the door as Pinkie bounces on her bed. "Okay, Nonny! How do you want me? On the floor? On the bed? Upside down? Ooh, maybe you wanna set up a gloryhole! Don't worry, I won't mind--"

I hop onto the bed, planting my hooves on her shoulders with a squeak--wait, squeak?

I rub her shoulders a bit. They squeak again, like I'm rubbing a balloon. In fact, she feels unnaturally smooth, almost like--

"Oh, I forgot to mention." She smiles wide. "Glimmy and I did some experimenting a while ago, and Twi was there too, and you know Twi, always worried about side effects--but this time, the side effect was amazing! It turned my whole body into a balloon! Twilight was super interested."

My jaw drops.

"I turned myself into a balloon, Anon!" she shouts. "I'm BALLOON PINKIIIIEEE!"

...Well, I might as well make the most of it. "So, you're just...made of--"

"Latex, yeah! I can streeeetch," she says, wrapping her forelegs three whole times around me. "I can beeeend," she adds, as she lets go to bend over backwards--so far around that her head ends up under her tail. "I can even blow myself up! Like a balloon. Twilight gets nervous if I don't specify that."

"Okay. Okay. I can work with this. Can you sort of, uh, roll over--"

"Like this?" Pinkie says, as she casually rolls around--leaving her lying on her belly, her front half folding back over her rump, with her face hovering upside-down at the perfect height for dick-sucking. She reaches out and boops the tip of my shaft with a giggle. "You like flexible girls, Nonny~?"

My wingboner answers that one for me. I line up with her mouth, carefully planting my hooves--I don't wanna knock her off-balance, but I gotta get a grip on the bed. When everything's sorted out, she rocks backward and smooches the very tip of my shaft--and I rock forward, and she takes it like...well, like a lubed-up sex toy. Because, in a sense, that's what she is. She's made of latex, after all. And her mouth feels exactly the right kind of slick...

"Mmf! Mfhghfm mff mm!" she moans, her tail twitching as my balls slap against her nose. I pull out.

"Whuzzat, Pinkie?"

"I said your dick tastes good, Nonny!" she squeaks out, trembling slightly. "Also, did you know I'm super into oral now? Twi said that my mouth is practically an erogenous zone now. Apparently, when I turned into a balloon, it couldn't tell the difference between my horsepussy and my face, so it made them both work the same way! Also I just like having dick in my face. Just rub it all over!"

God, she won't shut up. I stuff my shaft into her mouth mid-sentence and--after a brief but very arousing moan--she continues, mumbling nonsense around my rod as I start facefucking her. Her throat stretches, a neat cock-shaped bulge forming every time I thrust, but I guess she doesn't need to breathe either, because she still hasn't stopped trying to talk around it. She gently pokes my butt, and I pull out.

"HAAH~! Thanks, Nonny! You're pretty big, y'know? Anyway, you should try stretching me even more! Hold on--" She adjusts herself so that she's bending at the neck instead, leaving a lot less room for dicking. "Okay, now j-j-jam it in!"

The dumb hentai reference is arousing me and I hate it. But hey, I'm not gonna stop now--I slide it in again, all the way up to about the 3/4 mark before it stops at the bend between her throat and her chest. There's still a little give, and I can see my tip stretching out the latex--just a bit more...fuck it. I thrust again, hard. It stretches her even further, the rubber tightening around my tip as I push beyond what should be physically possible. She squeals around me, and I pull out--"You okay, Ponka?"

"Okay? Okay!? That felt fucking amazing, Nonny! Do it again!" she shouts, flailing her hooves wildly.

"Fine, okay, gimme a second--" I grab her face, eliciting another excited squeal, and shove my cock down her throat again. The rougher I go, the more mewling and moaning I get out of her--I hear what sounds like a little confetti bomb going off, and when I look down between her hindlegs, I see a puddle of marecum and a few scraps of rainbow-colored paper. Turning my attention back to her face, I feel myself growing erratic--feel the coming rush--and start to slow down, dragging it out a bit. Pinkie taps me on the butt again, and I pull out once more.

"Hooh boy that was somethin'. Thanks, Nonny, but I'm a bit stretched thin, and you won't be up for that for a couple months!"

"Wha--"

"But don't worry! You can cum in my mane!"

I sigh, and make ready to stroke myself off--but then Penka untwists, turns around, and tugs a bit of her mane out of the way to reveal...a hole.

"It's my secret fun times hole!" she says. "I use it when somepony wants a quickie but I'm all stretched out everywhere else. Also for stashing an extra bottle of lube, for lube emergencies."

"But--how--"

"I'm made of rubber, Nonny, I can be any shape I want."

...fuck it. I mount her head, from behind, and try to line up with this...hair-gina? Never using that word again. I press my tip to it, and--it sucks me in!

"Awww yeah, that's the stuff~!" Pinkie moans, as her mane starts milking me. "C'mon, Nonny! We gotta get this done before the chapter ends!"

"Wha--whuh--the fuck--h-hold on!"

"Shoot your goo, my dude!" Pinkie moans, as her balloony body tightens around me. I can't help it--I blow a load, pumping 'my goo' into her. She releases me, and I slide out, spurting a couple more streams of spunk onto her head--she turns as I unload, getting a nice even coat on her face and mane.

"Heheh, nice. You made a lot! Don't worry about the mess, it'll come right off. Perks of being a balloon~!" she says with a wink.

"...you know, you're less of a balloon and more of a--"

"Living sex toy? Yeah, but if I called myself that it wouldn't be safe for work!"
