Exploring a Giant, Nude, Sleeping Twilight

Part III

Underneath the Massive Ass

Meanwhile, down below, and inside and between the purple cheeks of heaviness and softness, Princess Luna was currently wiggling in place within her new confines. She hadn't expected the two hills of lavender to come crashing down on her so suddenly, a shadow blanketing her one second, a crack of the biggest ass she'd ever seen devouring her the next.

She slid in easily enough. Her arms were at her sides, and they were kept there, tightly, by the tautness of Twilight's fat behind. Worse yet was how pleasant it all was. The smell, the scent of heavy musk was thicker here, slightly tinted with sweat, but thankfully, Twilight kept herself very, very clean.

Stuck in the butt of my former foe! Not that... mind all that much. Luna wiggled from in-between the tight, curving walls, struggling and wiggling, feeling the cheeks shaking and jiggling, though immediately collapsing in the space created. And if she gets up, much less starts walking, then the rise and fall of her ass will rock me out.

It was humiliating. Utterly embarrassing to be a tiny girl caught in the bottom of a much bigger girl. Twilight was currently sitting on the side of the bed, vaguely aware of the itching sensation traveling up the crack of her ass, though for whatever reason, it felt oddly pleasant enough for her to not do anything.

In fact, the sleepy girl decided to play with the sensation a little, seeing how much of it was in her head. She wiggled her tush, not the biggest one around, but with enough junk in her trunk to obliterated the space of wherever she sat.

In shaking her ass, she felt the pressing sensation starting to fade. But Twilight didn't pay it much mind. With a shrug of her shoulders, and pushing onto her feet, she rose from the bed. She paused momentarily at the new sensations of weight. There was a magnitude to her now, a pull of force like a magnet to metal that yanked at her breasts, demanding they kiss the carpet below. It nearly broke the sleepy expression on her face, but with another lazy smack of her lips, Twilight went to go fetch herself some water.

Meanwhile, in the rising, falling, and shifting bottoms, caught snugly between the two grinding cheeks of purple, Princess Luna both loved and hated her life. It wasn't very noble for a princess of her status to wind up in the ass of another girl, having her face, chest, and rest of her body ground and pounded into by two, massive, rubbing cheeks.

Even worse was how their every rise and fall served only to drag her down Twilight's crack. Freeing her head slightly, Luna set her face to the side, seeing, through the slim crack of the purple behind the expanse of the massive bed becoming enshrouded in a haze while the two walked away.

Falling out here is not an option. Luna found it hard to think when the two walls of purple kept pressing into her body, throwing her back and forth. When she stretched, when she pushed, all that happened was her body sinking into the softness of the tush. It wasn't an opponent that could be beaten. It simply absorbed and humiliated her; an empty void that was filling faster and faster with Luna's dignity. And what's worse is that the punishment of Twilight's butt is the only thing keeping me from falling! Not only that, but I have to climb in even DEEPER to stand a chance at being safe during her walk.

After the umpteenth smack from Twilight's right cheek into her face, Luna managed to tilt her head back, the back of which sunk into Twilight's tush. She looked high up, the fatness and tightness of the ass blocking most of its inherent contents.

If I had to guess, then I would say I'm barely on the outskirts of her ass. That's not good. Luna reached her arms up, freeing her chest to be assaulted fully by the crashing of the cheeks. She shifted, crying and moaning at the immense weight of ass clapping into her softness. Deeper! I need to reach the deepest part of her rump before it's too late! The pressure may become unbearable, but it's better than slipping out from Twilight's ass!

It turned Luna on. It made her thighs rub together, the lips of her pussy started to itch, and for her skin to warm underneath the surface. Here she was, a tiny girl, climbing and wiggling herself deeper into the fat behind of a massive girl, one who was currently walking, unaware another was with her, caught by her, and being pleasured by one of her most private parts.

Trapped face first between the fullness of Twilight's cheeks, Luna realized was a prisoner of lust. Caged by her own growing arousal, there was no way to escape beyond the warden between her thighs: the only key to her release,

And it didn't take long for Luna to reached the center of the ass. She knew it was so when the spreading of her arms against the cheeks split them less. When they closed up quicker on the space her feet left behind. Soon enough, when the weight of both cheeks pressed down on her immensely, she tossed one final glance over her back, losing it at the fact her own ass was being smothered by the titanic cheeks—and that the crack she entered from was nowhere to be seen.

It was here that Luna would be forced to endure everything. Near the outward parts of the cheeks, the space was loose, but the clapping of Twilight's ass kept her snug. But now? She was at the center where they were held together, the weight of Twilight's fat bottom applied constantly. Rubbing. They were still rubbing together.

Knowing that there was nothing else for her to do, that the worst that could ever happen to a princess already did, Luna decided to resign to her fate. In this strange place, where the lavender filed on her back was the same one pressing into her front, Luna found movement still possible.

The air was tight. A dense smell of lilacs filled her snout. Musk. It still pulsated around her, faintly though, but a trace, a sniff, a lick of it was enough to flame her loins with passion. A low growl escaped Luna's throat. Now was the time for her to play dirty.

She gave up resistance. The pressure of the pressing cheeks was immense, sure, and though the tiny girl was snug between them—that didn't mean movement was impossible. Luna rose her arms, pressing against the expanse of purple overhead, a pointless fight which her arms only sunk into the devious depths of the cheek.

With her arms now over her head, nothing was stopping from the full weight of the shifting cheeks. The malleable cheeks seemed to cascade around her, squeezing her body from every possible angle. They rubbed and pounded into her tiny little body, flattening her breasts, sinking into the crack of her own plump ass, while all the while, her miniature hips flicked against the flesh of the cheek, feeling its warm surface of skin and fur beat against and into her pussy with the stimulation of sexuality that the tiny girl had been dreaming for.

Twilight rocked the tiny princess with her giant ass—and she had zero clues about it.

When Twilight rose from her sleep, it was because of the itches sprinkling all over her body, something she was vaguely aware of while she slept, but only actually snapping her from it when it concentrated on her breast.

After sitting up and doing a small, cute stretch, the haze in her eyes revealed nothing about her breast. With that cleared, she wanted nothing more than to sleep, but knew her body must have been trying to tell her something by waking her up.

Which she, of course, thought was a cry for water.

But as she stood on the side of the bed, that itch came again, one still there even after she scratched her pleasant ass. It was deep within her butt, almost caught between her cheeks rather than on one of them and, had she been a bit more awake, then she might have been a bit more worried.

And oddly enough, she didn't mind it all that much. Even more so when she started to walk, feeling the sensation trapped by her booty forced to crawl deeper into her bottom, thus becoming further caught by something like her ass. It was a powerful feeling. Something she enjoyed even much.

Maybe that when she went to the bathroom sink for water, she leaned down and stuck her ass out as much as possible, feeling her cheeks come slowly apart, feeling the itch, maybe even object there fall more into her butt.

Twilight gave a sleepy giggle. What the hell was she doing? Sticking out her bare ass all to accentuate the wiggling feeling caught within it, delighting in how it fell, sunk, and crashed even deeper into her depths. Something small caught and held within the confines of her ass.

Why did it make her lips water?

Twilight didn't know why she kept her butt out, leaning over the counter with a glass cup now in hand, filling it with water beneath the tap. Without any reason to do so, other than doing so anyway, she swayed her rump left and right, enjoying, the small, miniature bouncing and smacking on the inner depths of her supple cheeks. Like rolling waves in the ocean, the rhythmic movements jiggled her bottom nicely with an ebb and flow of flexing muscle under a fine layer of chub.

The sensation seemed to spasm in response, made wild by the teasing, but never being relived. She should have scratched there. Dug a finger into her butt and scratched wherever her cheeks itched. But the feeling was too good to pass up. It wasn't normally like this, so it made sense to enjoy it while her body still rendered it, because of her sleepy state, pleasurable.

With the cup filled and the tap closed, Twilight rose the former to the lips, ceasing the swaying of her ass and instead, with a grin, raising and dropping her hips, feeling the bounce of her heavy cheeks, their drop and their smacking. Within seconds, the cup of cool water quenched the dryness of her throat.

And the destination within her ass ceased from her smacking of her ass.

“Oh, well.” Twilight set the cup next to the handles, a surprise yawn escaping pass her lips. “It was fun while it lasted.” Still, unable to rid herself of the pleasure, Twilight clenched her cheeks together, feeling her plush hills of softness then transform into grinding walls. “Back to bed I go.”

Twilight walked back to her bedroom.

Luna wasn't sure how long she'd been stuck in Twilight's fat behind. Or how many times she had gotten off either. The shifting of the purple cheeks soon came still after some walking, allowing her to drink in the tightness of the air. That was, of course, before everything lifted.

“W-What's this?” Luna cried when the prison suddenly rose, the two sloping fields of purple lifting. Her tiny body slipped backward, further into the soft abyss. “It can't be! She's lifting her rump while getting water?”

But that wasn't all that she would be doing.

Slowly, surely, and quite scarcely, the two expanses of lavender swayed, the twin cheeks knocking her back and forth, moving her through the air, lurching her stomach, but yet, keeping her in the same place altogether. The powerful clap of her rump might as well been an ovation: the thunderous crashing of the monolithic bubbles deafened the poor mare inside, while the shifting movements commanded her body. Luna had never felt so powerless, the overwhelming thickness promising to be her salvation from the situation also held complete and utter dominance over her wriggling frame. She held no power here, complete and totally at the utter mercy of her captor whom wasn't even aware of her existence.

Did Twilight know? Did the vague notion something was trapped within her massive rump, and now, was seeing it fit to punish it with the very ass it had so desired? The swaying and shaking soon gave way to rocking up and down, and the thunderous claps of the Twilight's mighty ass nearly snuffed the life out of the tiny girl.

Her dark blur fur was flattened over by the bright fields of lavender. For better or for worse, the fingers jammed in her pussy were further beaten in by the clapping of the cheeks, the soft smothering of immense weight. To be crushing by something plush—such a thing wouldn't be possible in any other way.

Luna couldn't even dig the fingers out of pussy while she came, having them pumped and jammed, again and again, following by the slapping of the two massive cheeks. It was like being caught in the divot between two hills—only for them to come crashing together in the middle.

By the time the euphoria of her Gorgas started to clear from her mind, Luna was vaguely away for the rocking and rumbles coming from outside her purple confines. Twilight must have been walking again, normally this time, causing her cheeks to not be as aggressive as before.

It's a good thing I crawled all the way in, Luna mused to herself, enough space around her to pluck her fingers out from her cunt. They were soaked to the bone, her blue fur made even darker. Her limbs were limp, aching and resting. If I were to slip, I... don't think I'd be able to climb myself back to safety.

It wasn't until her giant owner stumbled back into the bedroom, nearly throwing herself on the bed and lying down, that the next problem for Luna began. Like a sea rising and parting, the quaking of raising bed sheet came muffled through the twin cheeks. The brightness of the lavender fur and skin illuminated the depths of Twilight's crack slightly, though the current of blanket threw over the whole of her body, the world dimmed.

And then distant snores soon followed.

“Quick to rise and quick to sleep.” Luna smiled. She was currently lying on her front on the bottom cheek, sinking into the softness slightly, while the top cheek flattened over her body without mercy. “My goddess clearly doesn't waste any time.” She laughed as she began her crawl forward. “Another thing to love her for.”

But Twilight had taken to a new sleeping posting. She now laid on her side. While this meant her left cheeks now became like a platform for the tiny girl, the right cheeks was now an immense and falling sky, covering the tracks Luna made the second she left them.

But the crawl wasn't all that bad. Luna had to push her body forward, using her hands to create a crack of space for her to crawl inside, leaving the space behind her to be claimed by the rolling tush. She may have suffocated if she were claustrophobic, but to her, all of this was magical.

And, of course, intensely sexy.

So. When her head popped out from the mile-long crack of the purple rump, Luna did so greedily drinking in the fresh air. Well, as fresh as it got underneath the blanket. The air was dominated by the smell of Twilight—her scent, her scent, her lingering musk. It must have been a few days since she last washed the bed, rendering it a wonderland of Twilight Sparkle.

And there was one coming attraction Luna had been dying to visit.

Princess Luna slipped out of the massive crack of ass near the bottom of its slope. She was able to sink into it, descending down the purple slide of the cheek, one that brought her close to the circular pillar of purple thigh in the distance.

L-Let's hope they're as soft as they look! Luna pressed her feet into the cheek, feeling them impressed and then launch out, casting her away from the cheek. She fell for a few feet, the outward slope of the cheek, its apex, catching her and bouncing her afar—directly toward the pillar of purple.

Princess Luna hit the plushness of the thigh rolling, a hill much like the rest, though more round than anything else. Wherever she seemed to touch down on this girl, softness and plushness and thickness seemed to be in abundance—and that was true regardless of whatever size Luna was.

Luna took a moment to gather her bearings. Raising her head with a shake, she glazed over her head, seeing the other round pillar of thins blanket the sky with tufts of purple fuzz, made messy by rolling about in bed. Only a gap separated the thighs from pressing, something, which, Luna was thankful for.

That wasn't the tightness she currently craved.

Luna kept to the top of the expanse of the thigh, the ground hard to walk upon, even more so than the breasts or ass. It was putty to walk on. Almost like traveling across a water bed. Luna had to fight the temptation to crawl once more. She suspected that it was the desire to have her breasts sink and press into the plushness of Twilight's thigh. Giving up the final act so early would only hurt the overall arc.

So Luna continued to walk. And her walk was a short one.

The roundness of the slope began to dive downward, granting nearly close to no space for Luna to walk on, causing Luna to glance to her right. She was in the spot between Twilight's crotch and ass, the sweet, smooth center in-between.

Luna came to the sloping walls, finding herself able to hold onto the fuzz here, thankful it was longer here than in other places. Holding handfuls of fluff, matched with her legs hugging the sloping softness, the tiny began her crawl, doing her best to ignore the scent of dense musk trapped within the strands, or how the smooth surface rubbed against the parted folds of her cunt.

And the crawl, thankfully, wasn't a long one.

Princess Luna traveled with one raised leg and arm at a time. While she scaled the underside of the girl, her face had to push through tufts of fur and bushes, the scent trapped within the buzz reeking of musk. It was enough to make Luna go crazy. Pulling her into a maddening spiral of unthinkable lust, much worse than the arousal she so recently freed herself from. To throw her hips against the sloping softness, to sometimes plant her face in the dense hairs, inhaling deeply, filling her lungs with Twilight Sparkle.

So it wasn't much of a surprise that, once she reached just underneath the purple expanse of the crotch, that Luna, embarrassed, humiliated, and horny was in a mad crawl toward the protruding mounds and the slick, sweet, and delicious, lavender folds tucked in-between.

And then Twilight rolled back onto her back, though thankfully, Luna threw herself into the dense foliage. Everything was still once more. The tiny girl began her climbing once more.

By the time the tiny girl was crawling underneath the stretching slit, which flew on over the horizon of the mounds, rising and, to Luna, blocking the view of the descent. With the ground of women now flat, she was able to stand on her feet upon the squishy flesh, enjoying, nearly moaning at how it welled up between her toes.

The smell. The scent! The blanket trapped in Twilight's odor. It was like being baked in a sauna. Knowing that her body went on forever, that her skin was a wonderland, her most private places amusements to be explored.

Oh! How the dirty thoughts itched and burned at the lips of Luna's pussy. She couldn't help the hand that dived down her miniature body, her palm gracing over the furs of her tight body, letting her fingers, ever so slowly while she walked, trace and play over her own pussy.

The reference was crazy! Princess Luna bore in mind as she approached the left, sloping and squishy bound that she was touching the same thing below, that she had two dark-blue ones of her own, that impressed underneath the pressing of her digits. Her mounds were tiny against her fingertips; Twilight's rolled on like sprawling hills.

Something Luna also wanted to roll upon.

But she saved her treat until she would be inside.

It didn't take long to climb the top of the bound. Some sweating. But being trapped underneath a blanket, stuck upon a girl the size of a nation, while being close to her most private and warmest of places would do that to anyone.

But then came the next problem. Luna now stood on top of the left mound, feeling her body sink slightly into the surface. But that was the least of her concerns. Taking a final glance upward, the thick ceiling of the blanket greeted her, allowing, only through filtering it, some rays of moonlight to illuminate her tiny world.

Looking downward, however, told a different story.

Luna's previous actions on Twilight's body, matched with the friskiness seen in the bathroom, led to the bigger girl becoming excited in her sleep. The tiny girl had already breathed in a year's supply of Twilight's personal scent, but now, it was filtering the air, dominating it, making it solely her.

Was it like this for all girls? Was that tiny smell to their noses speaking little of how much air they transformed down there? Or here, right now? Luna could barely hold herself back from the idea. Of being in the panties of Twilight as she got wet and hot, being bathed in her scent, drenched in her cum, becoming, much like the air here, property of Twilight Sparkle.

But that would be nothing compared to the next course of action.

Luna had enough teasing to simply be outside the source of her pleasure. Or Twilight's pleasure, for that matter. She gazed down into the purple abyss, the twin, plush, protruding mounds, once crashing tightly together in the center, now, due to slim walls that were tucked between them, pushing them apart.

Pride welled in Luna's heart. Had she done this? Her? This tiny little girl, with little use of her magic, and zero use of her wings—it was always more fun that way—able to make the massive and her giant pussy ready to play? Well, seeing how the folds gave way to the endless depths below, it was pointless to be getting a big head now.

There was no winning when playing with Twilight's pussy, not when its depths were delicious and never-ending, with close to no light going in. This wouldn't be a matter of playing. This was a matter of getting devoured. Twilight's pussy opening up wide, tasting, licking, and eating the tiny princess. It would seal itself tighter once she had gone it, finally given its treat that would deliver the pleasure it sought—even if that pleasure only came from knowing a tiny girl was cast and locked inside the giant pussy of another.

“There may not be getting out of this one,” Luna said to herself as she stood at the edge of the mound, gazing over the border to peer into the tight hole below. It was open, waiting for pleasure, delighting in the suspense of devouring her. “At least, not for a long time.”

Being cast away inside Twilight's pussy, even for a thousand years, didn't seem all that much like punishment to Luna.

Which was why she stepped off the mound without hesitation, or why her wings did not flutter while she fell. The only thing to happen was her horn lighting in a soft blue. Its glow cast around on the rising setting around her. The texture of the folds, nearly hidden behind the layer of purple fur, were detailed to Luna's eyes.

Gazing up, she saw the tops of the two mounds, both of them shifting slowly together, and even though she had yet to make an impact, Twilight's pussy could sense the falling treat. Below, her round, tight little hole opened further, allowing the falling princess to slip into it without restriction, without even having to touch.

The dimness of moonlight disappeared around the falling girl. The air, once bearing some freshness, thickened into pure musk and girl. The skin and squishiness of the folds and the mounds transitioned into the pulsation and undulation of the tight tunnel.

“N-Nngh!” The muffled moan came from everywhere and nowhere, somewhere outside and somewhere inside, deep and close, but still sounding very far away. The tunnel lurched forward, tightening closer together while vines of white liquid hung from the ceiling. “Mmmhmm.”

Meanwhile, the falling and tiny girl, seeing the rising bottom of the tunnel, braced herself for impact as the massive girl with the fat ass finally sat up slightly. Luna crashed into the ground, the spongy ground breaking her fall. The impact made her body pressed into it, causing Twilight's juices to well up and into her face, sticking to her chest, darkening her fur, coating her pussy in juices other than her own.

Luna should have been mad or, at least, slightly irritated. It wasn't like her to take such embarrassment and humiliation willingly. It was resentment to her sister, and shame to her own ability, that caused Nightmare Moon to come into being.

But this? Being dominated by the towering pussy of the one who had beaten her, who now had her trapped in her cunt, covered in her juices, with only more on the way... why now was she loving every second of this? Why did she, the moment Twilight's buttery honey splash onto her face, respond by rolling around in the tight passage, enjoying how more of it slathered onto her, or how the tunnel shook and bounced her around?

It was punishment, in a way, but also a reward at the same time.

Both of those things, for whatever reason, made Luna feel whole.

“Glad to see you enjoying yourself, dear sister of mine.” The voice, this time, was not muffled but clear, close, and familiar. “Out of all of our subjects I expected to find you with, my dear Twilight was the least I suspected of finding you inside.”
