Holy Fuck, I Pissed Off a Giant Rainbow Dash

That's it.

Easy now. There we are. Just... put one wrist forward, push one foot back, crawl along and underneath the gigantic bottom, and hope that the air keeps. There were only a few miles of sheet and ass until freedom could greet me.

Celestia, this was a risky business.

It's hard to describe my surroundings, but I'll do my best. I'm currently crawling in-between two globes of giant, blue cheeks. They shift slightly, sometimes rubbing towards me, and I roll along, doing my best to keep straight in the gigantic... ass-crack.

Y'know, sometimes I really fucking hate my life.

Alright. Maybe I wasn't fair with that one. The area wasn't dark but dim. Rainbow's monolithic body, hind legs tucked in and forelegs erect on the bed, sat straight. Her once small and petite body was now the biggest thing I knew. She blocked most of the light, though some escaped between her legs.

“Well fuck.” Above me hovered the blue slit of the girl, only an inch away. “It doesn't matter how fucking small I am. One touch and she's feeling my ass for sure.” I sighed and shook my head, resuming my crawl. “Just keep low, Spike, and don't do anything stupid.”

Like anything ever went that way with me.

“Hmm?” the earthquake of a hum rumbled all around me. The shifting of the gigantic ass slowed. “Now that's strange. Why aren't I feeling anything poking at my rump?”

Light blinded me from behind. The structure that was Rainbow Dash sunk more into the bed as she put more weight onto her butt. The crazy girl! She meant to sit on me fully! If she didn't have me crushed before, then enduring her whole weight would just make me go splat!

Was Rainbow really that far gone? She couldn't be. She must have known I had moved, that I was trying to escape, that I was somewhere relatively safe. Her asscrack wasn't what most called safe, through having to date the girl to touch it and, well, being shrunken underneath it—but fuck, it fucking better being caught in her crevice between her cheeks than having either or crush my bones.

“Where ya hiding, Spikey-Wikey?” Rainbow giggled. “Or better yet, what are ya hiding from me? I'm too big and smart for you or your lies to slip away.”

I wish I knew whatever the fuck she was going on about. Lies? When the hell I lie to her?

The ceiling that was the twin cheeks pressed down further into the bed. The frame squeaked, the sound billowing into my ears. My heart raced only when the mass of the cheeks flatten against the bed, and with no more space below to take them, began to flatten toward me.

“Fuck,” I muttered as I continued my crawl along her crack. “Don't think. Just get the fuck outta here... alive.”

“Really?” Rainbow said from above her massive body. “Not even an itch against my butt? Now that can't be right.” The cheeks stopped flattening toward me, and for but a brief second, everything was still and silent.

I held my breath.

“Maybe you're tucked away somewhere naughty.” All of a sudden, the cheeks pulled up from the bed—fresh air blowing into my snout. I went to exhale but found that breath squeezed out of me. “Let clench to find out!”

“Ack!” I groaned and somewhat cried as the sides of the cheeks crushed into my own. It was pain and pleasure—pain resonating from every part of my body but one, and pleasure dripping from that one part, my aching cock. “Oh, c'mon! Now's not the time to be getting horned up!”

My shouts hadn't mattered and for a good reason. Rainbow Dash had caught me in her ass, squeezing her cheeks together on my sides, plushness enveloping my body and sinking me deeper into her crack.

Fantasy became a reality as my horrible situation became my ultimate pleasure. I was trapped by a mare who was incomparable in our sizes. Rainbow couldn't see me and barely felt me, yet her cheeks, her firm and toned ass clenched—and at once escape became impossible again.

Every squeeze pulled me deeper into her crack; every clench crushed my cock. The softness of the side of her cheek would let my dick press into it, sinking not even an inch, caressed by her fur before being rebounded as the cheek sunk away.

“Oh yeah, now this is a work-out!” the voice rumbled almost through her ass, and at last, her cheeks had split far enough for me to drop. My stomach churned as I fell, only for a second or two, until my hit and sunk into the mattress. “But that was just stretching, right, Spike?”

“Agh.” I slowly rose to my feet in the niche underneath her bottom. Stumbling to my feet, I glance up at the giant, quivering pussy. It winked. “Oh fuck... not like this...”

“Like what ya see, Spike?” The folds above split by an inch, exposing Rainbow's slit in all its glory. “Your cock has gone in there a few times. But you? I don't think I could ever say I had a full-blown dragon inside my pussy.” Giggles rained down from above as the pussy squatted down and closer to me. “Revenge is just perfect, don't ya think? For whatever reason, my marehood wasn't enough to hold ya to me, and now, you're gonna drown inside the thing!”

“You can't be fucking serious!” I threw my claw out to the side. “Can you even hear me right now? Call this shit off right now!” Tilting my head back, I shouted at the top of my lungs, “Will you stop fucking about so we can just talk!?”

“Oh, we can talk alright.” I cried as the pussy came crashing down from the sky, knocking me down onto my back as mounds held down my arms. Her slit made me slick with her arousal. “You can talk to me from inside my pussy.” The weight of her pussy increased so much that we impressed into the mattress; Rainbow must have lifted a foreleg to laugh onto. “I'm sure I'll be able to hear you from deep inside me.”

What do ponies tell you to do in a dangerous or anxiety-ridden situation? Breathe deeply. Wanna know something they don't tell you about that? It's fucking hard to breathe when you've got a mile long pussy not only dwarfing you, but have the full scent, the full arousal and musk of a mare filling and expanding your lungs with total thickness and very little oxygen.

And you wanna know the worst fucking part about that?

It made me hornier than I thought possible. Something snapped. I snapped. Played around by a giant ass, crushed by a pussy bigger than my home, and my lungs filled with nothing but the lust of Rainbow Dash. Fuck it. Fuck it all to hell. She thought this was revenge? Shrink me? Humiliate me? Stuff me in her pussy thinking it would cause me misery?

Fuck you, bitch.

This was just going to excite me.

“Alright then!” I screamed up at the giant mare which, really, was just me screaming into her snatch. “You wanna punish me by putting me in your pussy? Fine. Game on!”

On either side of me where her slick folds. Grabbing each with my claws, I squeezed them as I pulled myself from underneath her slit—not to escape, but rather, squeeze myself through it. It caused some confusion for sure: Rainbow shifted from me moving.

“The heck are you doing to my pussy?” Rainbow's voice quizzically asked. “You're supposed to be scared! Why aren't you trying to escape or something?”

“Because I wouldn't be able to knock some sense into you otherwise,” I muttered to myself, forgoing logic with her for the moment. She was wet; I was hard. Might as well blow off some steam—maybe that would make her sensible. “You're my friend... with benefits. And this?” I'd squeezed my way along her slit, the slick fur her of her vulva rubbing along my sides. “This ain't anything different from our other sessions.”

I'd reached the top of her slit and held myself exactly there. My head was the only thing to stick out from her pussy—her folds were tight enough to keep me locked between them. In the dimness of the niche, her puckered ass hole loomed above. It winked.

“Seriously, Spike,” Rainbow's voice vibrated all around me in a solid hum, “what are ya doing to me from there? Ah, screw it. Get out of there. C'mon.” With my body tightly held by her folds, my claws were free to reach the top of her pussy, slipping underneath a familiar hood, and in blindness, my palms touched upon something hard. “Ack! W-What are you doing down there? Don't make me send a hoof to getcha!”

“Really think a hoof would do the trick, do ya?” I laughed as Rainbow's clit popped out from under its hood, engorged. My claws rubbed around the small ball, currently bigger than my body, feeling it become excited due to my work. “Small, and I'm still swell at getting a girl going.”

“Will you—nnnnnngh.... hmmm—q-quit that!” There. Right in her voice, in her very tone, the dripping arousal that matched the output of liquid coming out from her pussy below. I even looked down to see her folds becoming agape below, opening up and showing off her tight little hole. “T-That's it! I-I-I don't want you inside me anymore.”

“Oh yeah? Tough luck with that!” At once I let my claws drop, and feet kick against her folds. Rainbow was wet and loose below, and because of slick I was, I slipped right from her folds and began to fall to below. “Better get that hoof down to me quick!”

“Tempt me why don't ya!”

The giant structure of the mare leaned back as her rump scooted forward. Smiling as I fell along her bottom, her slit raced up along me, and after a few seconds, upon reaching the base of her pussy, I reached out to her heavy opening.

“Ack!” Rainbow whined as a shudder coursed through her body. The sudden surprise gave me a few seconds to grab the bottom of her opening, and, using her lower lips for support, pulled myself up and rolled into her entrance. “H-Hey! Knock that crud off!”

“No can do, Rainbow Dash!” I cried from on my back, laying at her entrance while I recovered my breath. “You can crush me with that hoof of yours on the outside.” I rolled over onto my stomach and, standing up on her dripping snatch, I faced the small, partly opening hole that was the entrance of her pussy. “But on the inside? Everything won't be so big, and we can finally talk!”

“Not on my watch!” At once my ground, her body, rocked and rumbled as she moved about. Light. Blinding light covered my eyes. Rainbow's bare crotch was now exposed to the outside word, distant objects blurry and incomprehensible. “There's no way I'm letting you get off to your punishment!”

“Too bad for that, then.” In the sky dropped the expanse of her blue hoof, a long cylinder that stretched well beyond the corners of my vision. The surface of the hoof was aimed at me, and like a slow moving rocket, it fired towards me. “Hope I'm better than the rest of your toys!”

I turned back around to the opening of her pussy. It was crazy how something usually so small was able to dwarf me now—like some kind of door that let me inside the body, the very landscape of Rainbow Dash.

It killed me. It really did kill me to know this. Rainbow Dash was this giant thing that not even a thousand of me could reach the ankle in her leg. She was her own world unto herself, and knowing that I was entering her—another being entirely—just made my cock so fucking hard that constant analysis would never be able to explain.

Dropping to my knees, I crawled toward the bottom of her pussy. The small hole was currently open, a trickle of marecum leaking along its ground. I paid that no mind as I crawled forward, putting my claws through the hole—wrists seized by her walls.

“Augh! Ahhh. Ah ah. Oooooooooh.” Rainbow flicked her hips, the massive thighs shooting outward and making me along for the ride, causing my arms to whack around her opening. When the beast was done, a moan escaped past her lips. “Oooooh yeah, that's the stuff. Heh.”

Crap. Oh, crap on crap in Applejack's farm. During the sudden flick of her massive hips, my body was shot out from her pussy, where my legs dangled out from her massive pussy. But my arms and claws, those were still stuck inside her pussy, held tightly by her clenched walls.

And then the hips lurched further as the titanic blue body above leaned back. Rainbow put her crotch on full display to her distant muzzle. I hung from her pussy, and in my vulnerable state, I looked up, up past her slim stomach, past the soft, blue furry expanse of her chest, and then, then I saw her.

I was small, but let me tell you, there's a big difference in being small than feeling small.

“Oh... oh.” Rainbow's impossibly large muzzle was blurred in the distance, so high above that saying she was the very sky itself would be an insult to her statue. No. She was like a goddess watching from a plane I could not explain, her mane a very ocean above her head that fell along her head. Her eyes. Her eyes. Rose colored and the size of planets themselves. “You look... stuck.”

Rainbow must have felt it too. Celestia knows she saw just how big she was. I couldn't beat an inch on her body. This world, this massive world dwarfed me with its every object, big or small, and the only thing, the only place that was of scale to me, that was normal to me was a part of her.

Rainbow was truly a world to me, or, at the very least, a part of her, be it her mouth or pussy could become a normal place for me to stay... for me to live. There's no way I could navigate this world at this size without risk. But she, my Rainbow was a vessel that could protect me—but only if I was inside her.

Tiny and little Spike stuck inside the body of once a dear friend.

“So... you ready to drop out of me now?” Rainbow said from above. “You know you can't take me. There's just... too much of me and so little of you.”

“I know that!” I shouted back up at her, kicking my feet at the fur below her snatch. “But you seriously think I'm gonna roll over with this? I'm getting my word in whether you want to hear it or not.”

“And that totallyis not happening!” Rainbow cried again. From behind and below, the forelegs stretching down to the mattress suddenly rose, slowly and without sound, raising and crossing over the heavy chest above. “All you're going do is feed me some BS excuse about what happened!”

“And I don't even know what happened!” I slid my body onto the bottom of her pussy again, feeling her walls clench and pull at my arms. Looking above, the giant muzzle of the mare was looking away, perhaps unaware of the actions of her pussy—like it had a mind of its own that only I could experience, and by the way it pulled at me, endure. “Neither do you, either! So we're gonna get this sorted out, one way or another!”

“W-Wait!” Rainbow's body shook from above, and the shock almost hit me—but I was too busy working at her entrance, letting the walls beyond her hole suck me ever deeper into her pussy. She hadn't realized what her most sensitive area had been up to. “Nuh-uh! You're not gonna make it out of there alive.”

“Just watch me.” My head was next to sink past the hole and into the tight cave of her pussy. The canal was spacious at first, dim but not dark, light spilling in from behind me. Letting myself crawl forward, the walls around me clamped on me, squeezing me and tasting me, carrying me further down the tight tunnel. “We're gonna talk one way or another, marefriend!”

“Alright then! That's the way you wanna play? Then I'm horny enough to be game!” the pink walls around me rumbled in tandem to the voice of their owner, which was distant yet all around me. “Enjoy my pussy, Spike, because you're not gonna get out of it for a really, really long time.”

That didn't matter much to me. Closing my eyes and breathing deeply, the surrounding walls clenched around me, squeezing me, cum welling from them and brushing over me. Oxygen was scarce among the overpowering musk, but I still inhaled okay.

The sensation I focused the most on was my cock. It tingled between my legs, warmed by the heat of the snatch I was inside, crushed and soothed by the soft walls and their sporadic clamping. For once I felt at ease, calmed by my surroundings—the tunnel of the pussy didn't dwarf me, if anything, it was the only thing that felt normal and to my scale.

Which made me chuckle. It really did. This normal space existed only inside the body of another. My home could be in her cunt, and if she had been unaware, then I could have settled here without her knowing. She'd go about her day, walking and working, flying and playing, never notching the dragon placed in her pussy.

So we continued our little game, and for the time being, I enjoyed myself in this absurd situation.
