Rainbow Dash wakes up tied to Pinkie's bed naked and has no idea what the party pony has planned for her. Did I mention she was naked?

Warning: Contains mind control, Cum Inflation, Futa / Female, and tons of wiggles!

When Pinkie finds the power of a god (In her plump, jiggly cheeks no less! And no not those cheeks, think a little lower), can she handle the infinite possibilities? But of course, every god needs tribute...

Chapter 1: Let It Grow

My eyes opened, immediately closing them tightly as the light of the room made them sting. I quickly adjusted to the brightness and saw I was in Pinkie’s room, but no one was there. “Pinkie? Mr. Cake? Anyone??” I called. My face blanked as I felt a breeze. My eyes shifted downward and I saw I was tied down to the bed and my clothes were off. I yanked roughly at the restraints and quickly tried to cover myself up as I heard footsteps climbing the stairs. Knowing there was no escape I closed my eyes, taking a deep breath and letting the realization that whoever was coming up would see me.

Pinkie burst into the room with a large smile on her face. “Heeeey you’re awake!” She giggled loudly.

“Pinkie what the hell! Let me out.” I groaned, struggling against the ropes again.

“We can’t have that silly! You still have to pay tribute.” Pinkie said with the same stupid grin on her face.

“What?? The hell does that mean? Just let me out.” I groaned, glaring up at her. My heart skipped a beat as she started to undress. “Pinkie what… are you doing?!”

“Oh you’ll see!” She said, taking off her pants to reveal a small pair of underwear covering her nethers. But one thing was obvious… The pair of fuzzy balls dangling there, each testicle on either side of the thin g-string of her panties.

“How the fuck did you get a dick?! Did Twilight…” I started, my words trailing off as my gaze clung to the growing shaft that strained against the front of the outfit, only tightening the thin strap that was gripping her scrotum.

“Nope… all natural.” Pinkie bit her lip, obviously reveling in the strap that was continuously tightening against her balls by the still growing monster.

“That’s… not possible…” I mumbled, growing entranced by it.

“He… made it bigger… he makes it as big as I want…” Pinkie said, her face growing even redder than her natural complexion. I could see her chest moving faster as the bouncing breasts on her chest indicated her breathing was turning into a lust filled pant.

“Pinkie… just calm down…” I stammered nervously as she approached me.

“I just… I need to… I…” Pinkie said, her voice extremely strained as her eyes clamped shut tightly.

“What…” I mumbled. There was a tearing as the panties she was wearing snapped, her new package bouncing free and pointing directly at me.

“Ahhhhh… phew!” Pinkie said, wiping imaginary sweat from her forehead. “Any longer and I think I might have exploded right there!” She giggled.

“What… how is it still growing… Pinkie I…” I mumbled shakily, slowly realizing the situation I was in.

“Once I’m turned on, It won’t stop growing until… until I put it in something…” Pinkie said, her mouth hanging open as it slowly continued to stretch along with the heavy sack filling even more underneath. “At least… that’s what he told me…”

“Who’s he??” I said

“His name’s Glute. He lives in my pooper!” Pinkie spanked herself, giggling as the flesh on her large rump rippled like fresh gelatin.

“Pinkie are you high?” I asked bluntly.

“No I’m low.” Pinkie said, climbing onto the bed. My eyes widened as her bobbing member slapped noisily against my stomach and slowly stretched in between my breasts, pushing them apart slowly.

“Damn it Pinkie get it away! It’s drooling everywhere.” I groaned as it started coating the front of my blue fur in thick pre-cum.

“First things first! You need to be converted.” Pinkie bit her lip.

“What the hell is that supposed to meMMMPH!” I screamed as she quickly flipped around and shoved her ass directly into my face. My eye twitched as a twinge of anger shot through me. “Pnnki… gt… of… m. “I muttered. My eyes widened further as her ass seemed to grow slightly, maybe it was just my imagination. I soon realized that it was real, and my entire head was slowly being engulfed by her growing bubble butt.

“Oooo ehehe!” Pinkie giggled loudly. “Just snuggle right theeere.” She moaned as my face slid between the crack. I struggled violently against the bonds in a final attempt to free myself. The lights went out as her ass covered my eyes. The horror eventually set in that I need air. My head thrashed around, trying to free itself from the jiggling flesh that was Pinkie, only causing her to moan loudly. All sound was drowned out as both cheeks surrounded my head and clamped together, forming a seal around my head. I frantically tried to escape, quickly being interrupted by a voice.

‘Don’t struggle.' It said. It was a calm voice, a relaxing, soothing one.

“Wh… what?” I said aloud.

‘Don’t fight it. It’ll all be over soon.’ The voice said. An immediate wave of adrenaline coursed through me, making my entire body relax for some odd reason. I felt safe, like nothing could hurt me here. Like I belonged with my face engulfed by Pinkie’s glorious backside, lik- What! What am I thinking? This is all wrong. I should be… I…

My thoughts were cut off as the light of the room hit my once more. I stared at Pinkie as she pulled herself off my and kneeled down in front of me. “Now I’m going to put my schlong in your meat socket!” Pinkie giggled. It was at that moment I realized I was no longer bound to the bed, that I could get up and leave. But my legs didn’t listen. Instead of jumping up and running, they spread apart, revealing the pink pussy that stood out from the light blue fur lined across the rest of my body. Why was I doing this? And why was I so wet all of a sudden…

“That’s the spirit!” Pinkie said, her smile beaming down at me as she mounted me and aligned the tip of her length to my entrance. It was that horrifying moment that I saw the titanic throbbing monster in front of me. It had been growing the entire time, and she was about to put it in me.

“Th… that’ll… never fit…” I stammered, my head feeling slightly woozy as the thought of leaving grew wider than the dick as thick as my leg that was teasing my lower lips. Her hips jerked forward in an attempt to jam it inside, failing and roughly grinding the tip across my slit and rubbing against my clit hard. I let out a loud gasp from the sudden spike of pleasure shooting through me. Pinkie’s tongue poked out of the corner of her mouth as she fiddled with the shaft so prominently displayed, attempting to push it into me.

“C’mon get in… if you don’t go in you’re going to keep growing and we’ll break her!” Pinkie said to herself. “Oops… too late… she’s doomed.”

“P…inkie… w… wait…” I mumbled, my face growing red as I slowly lost the strength to do anything. What did she do to me? And why is the thought of her tearing me apart turning me on? Because that’s what’s going to happen if she sticks it in me…

My snatch tightened in an attempt to keep the monster knocking at it’s door out, but she continued to prod it, adding more and more pressure until my body was rocked by a sickening stretching.

“Ohhhhh theeeeere we goooooo.” Pinkie sighed blissfully as the head found it’s way in.

“Piiiiiinkie!” I screamed, gripping the bed sheets tightly. “Pinkie no!”

The thin slit stretched endlessly around her engorged member that still felt like it was growing. Her mouth had fell open and she slid another foot or so in. I could feel every inch sliding in, causing chills of both pain and pleasure to sweep through my body. As much as I wanted her to stop, I wanted her to keep going just a little more. What’s happening to me…

“Oooopsie…” Pinkie said, looking down at my lower half.

“Wh… what…?” I mumbled through heavy breaths.

“I thiiiiink it’s ruined…” She said almost apologetically.

I looked down and saw how wide I had been stretched, and how I’d never be able to have sex with anyone else again. Something in my head loved that idea, and told me that it was okay. I was meant to be here, with Pinkie, forever. “That’s okay… just keep going.” I said. Yeah I wanted this. No no… I deserve this! No one else should have this dick but me, It’s all mine!

“Okie dokie lokie!” Pinkie said, causing me to scream again as she forced another foot into me, visibly bulging my stomach out. I looked down and saw the outline of the cock plunging itself closer and closer towards the core of my being. Our hips finally slapped together. “Ooooo that’s not good enough.” She said.

“What… what are you talking ab- NNGH! OH GOD!” I screamed again as I felt her start to physically grow inside me, not in width, but length, forcing itself against my cervix.

“Theeeere we go… Now we just need to get in there!” Pinkie giggled. She moved her hips back until just the tip was in before jackhammering herself forward, bashing it against my womb’s shield without mercy.

“PINKIE! PINKIE PINKYHMNPH NHAHHHHHHHH!” My screams trailed off to inaudible babbling as the pleasure of each pounding both shook my voice to oblivion and replaced it with choked moans.

“Knock knock! Package for my wittle Dashie Washie!” She giggled as her thrusts picked up speed somehow, hunched over and clinging to my hips like a tick in need of blood, even though she had plenty down there. My thoughts were scrambled by the mind numbing surges of pleasure I was given by the mini-orgasms each veiny thrust was offering. My tongue flopped out and was tossed around by every violent shake of the bed I was so recklessly being pounded on.

“Eehehee! I can feel something building up down there… He said it would feel tingly!” Pinkie laughed loudly as her thick mass started to twitch from the release that was so dangerously close. My brain went on overload as the biggest orgasm yet hit me, locking Pinkie in place as the back arching, toes curling, eye rolling sensation exploded through me I sat there in utter bliss for a minute before going limp, panting heavily on the bed.

“Pinkie… that was… awesome…” I chuckled, feeling my sanity returning to me for the first time since we started. My face blanked as I noticed hers, seeing the absolute surprise stabled to her expression. Her eyes had rolled back and her features were locked, extremely tense.

“Phhhntph oh… oh oh OH! OHHHHHHMMMMPH HOOOOOLY WOOOOWIE ZOOOWIE!” Pinkie wailed, her head falling back as the tip of her dick flared wide.

“Pi… Pinkie wait…” I said quickly, trying to push her away as I felt her dick start to swell from the oncoming orgasm that has been delayed for who knows how long. “Pinkie pull it out now!”

“WEEEEEEEEEEE!” Pinkie screamed as the first load shot at my cervix, sending a shiver through my spine.

“Pinkie no! NO PINKIE!” I shouted as I felt another hit, and another, and another. My eyes widened as It packed so much in that my cervix finally gave way. Almost as if Pinkie sensed it, increasing the already prodigious loads to reveal her true orgasm. My womb was filled in an instant and my stomach started to stretch in order to make room.

“Please god! Pinkie PULL IT OUT!” I gasped as my bloating gut continued to swell larger until it pressed against my face, threatening to smother me. Finally I felt everything settle, my stomach resting as her orgasm stopped.

“Ummmmmm…” Pinkie said aloud. I felt a small tugging inside of me, making me worry slightly.

“Um? What’s um mean?” I asked nervously.

“It’s stuck.” Pinkie stated, scratching her head curiously. She moaned every time she attempted to pull it out. “Ohhh it feels so good…”

“Stuck?! How can it be stuck! Just pull it out…” I said frantically, wanting to get her out before she came again. I hoped she was empty, but who knows how much she still has in that freakish beast.

“Oh Dashie… I feel tingly again.” Pinkie announced as she started playing with her breasts.

“Stop doing that! Take it out right now! Pinkieeeee!” I shouted, desperately trying to free myself from the pole that I was impaled on.

“Ohhhh Dashhhhhh OHHHHHH HERE COMES A BIG ONE!” Pinkie shouted. Instead of pulling, she pushed, forcing the flared head into my womb. The cervix that once acted as a barrier, now formed a watertight seal around the head.

“PINKIE PLEASE STOP! I… I CAAAAAAAAN’T NNNHHHGH!” I groaned as I felt my distended midsection gurgle and jiggle as it began to grow once more.

“Hee hee! You’re going to be sooo big!” Pinkie said, kneading my stomach as it continued to press outward. “We’ll do this every day don’t worry!”

“Oh god… I… I can’t… bllng…” I sputtered, unable to find the words to speak anymore.

“Juuuuust sit tight. Get it? Cuz you’re tight! Well maybe not after this but… Maybe Glute will let us go after a few more.” Pinkie giggled.
