[1shot, prose] Sleepy Siblings (F/F, Oral, Full Tour)

	“Rarity...”  The little sister's voice squeaks out quietly as her hooves rock her older sibling gently.  The adult unicorn awakens with a huff as she sits up on her plush bed, the silky blankets roll gracefully off her white body.  She removes the frilly sleeping mask from her face, revealing heavy bags beneath her eyes.  Rarity sluggishly turns her body to the meek filly as she places a hoof to her back.  Lazily cracking her back, her eyes drift down to her sister as she leans against her pillow.  Work has done its toll on her this week, and her body desperately needed rest.

	“What is it Sweetie, big sister is trying to... sleep...”  She yawns deeply as Sweetie Belle climbs up Rarity's bed to snuggle in close to her.  The older unicorn instinctively brings the little one into a hug as she lays back onto the beckoning bed.  Sweetie grabs the covers below with her magic as she slips it over the both of them.  Rarity closes her eyes as her sister mumbles out her reason.

	“I had a really bad dream, can I sleep with you tonight?”  That was a half truth.  While her dreams weren't terrible, Sweetie has been craving for some sister time.  Rarity has been toiling away in her inspiration room all week, and Sweetie Belle missed being with her.  With Rarity's work finished in time for the weekend, the mischievous little mare took the opportunity to slip under the covers with an exhausted clothier.

	“Yes, yes... as long as you don't wake me up... for anything...”  With that, Rarity drifts off into an immediate slumber.  Taking advantage of the unconscious sister, Sweetie Belle nuzzles her big sister's nape, feeling the smooth coat brush against her snout.  Her stubby legs reach out to the warmth of Rarity's underbelly, feeling the radiating heat against her hooves.  Scooting in a bit closer, she smells a faint scent of vanilla as she presses her body against the larger pony.  As she prepares to fall asleep, a loud hollow grumble shakes Rarity's belly.  Thinking back on this week, Sweetie Belle rarely saw her sister remove herself from the second floor to eat.  Work typically comes first for Rarity, even before basic needs.  Sweetie frowns at her sister's neglect as she starts to shake herself from her sister's hooves to get her a snack.

	Unfortunately, Rarity's iron grip keeps Sweetie in place, trapping the filly between the long marshmallow forelegs of Rarity.  As she accepts defeat in slipping out, a warm, wet sensation crawls against the top of Sweetie Belle's head and through her poofy mane.  Rolling her eyes up, she sees the open mouth of her beloved sister slowly descend upon her head.  Frozen in confusion, she only stares as the maw slowly stretches to accommodate her sizable body.  The fashionista's lips crawl over her face until she stops at the base of Sweetie's neck.  Her sister's words echoed in her thoughts, reminding her not to wake Rarity up for anything.  While being swallowed whole scared her, the alternative of being scolded seemed like a worse alternative to the young mind.  Her thoughts are broken as she feels Rarity gulp her down, the distended jaws throw Sweetie's head into the tight entrance of the throat.  As the unicorn's body pulses around her, Sweetie stifles a laugh as the pearly whites of the generous pony gently graze her underbelly, tickling her pudgy belly.

	The body of the tiny unicorn continues to lurch forward into the dark digestive system of the posh pony.  Doused in the warm oral fluids of her sister, she gags as she accidentally sips at the thick broth as she tries to breath through her mouth.  The smell of a hungry belly fills her nostrils as the slippery tunnels pulsed around her.  Halting to a stop, Sweetie's head is forced against the entrance to the stomach as the esophagus slowly pushes her against it.  Thinking that she might be too big for the muscular entrance, it suddenly slurps up her head as she is forced into the tiny space.

	Outside, Rarity scratches her middle as the oval bulges of a smaller pony travel down her neck.  Her face visibly strains with each unconscious gulp her body does.  Sweating bullets, her body fights to keep the oversized meal down as the first large bulge slips underneath the round, plump belly of the white pony.  As the next series of lumps follow suit, slithering beneath the milky coat of the mare, her body lets out a giddy squeal.  A thin smile forms on Rarity's face as the sensation of being full keeps her in a sleep-induced state.  With her tummy no larger than it was before, faint traces of movement can be seen beneath her coat.  The meek struggles of Sweetie Belle, though mostly absorbed by the thick fat of the older pony, jiggles the pliant orb that contained her.  Soft murmurs of disapproval can be heard from within the cushioned stomach as the digestive organ eagerly churns its contents.

	In the dark, humid belly of the dozing pony, liquids pool around Sweetie Belle as the sharp stench of gastric fluids tickle her nose.  Though the stomach churns against the vulnerable body of the filly, rubbing the stomach juices deep into her stained coat, Sweetie only found it an inconvenience.  The sweltering, thick mixture harmlessly rolls off of her skin while the stomach kneads at her body.  With no room to move, the young pony submits herself to the whim of her big sister's body as any attempts to reduce her to nutrition was futile.  She grumbles as she feels her world flip around and feels Rarity's weight press her against the bed.  Sweetie only sighs as her fleshy sleeping bag only tightens around her, practically fitting to her form.  Before she can complain into the fatty tissue, a sharp yank catches her attention.  Unable to fight back, she surrenders her body to the muscular forces as she is pulled into the winding maze of intestines.

	Snoozing peacefully, Rarity snorts as a large lumpy form rises out from beneath her skin.  She attends to the itchy mass by grinding against the bed, thrusting into the mattress to help move it along.  The gyration of her hips force the pony-shaped bulge to creep forward as her guts gurgle in distress.  Rarity's face scrunches as she slowly approaches consciousness from the pangs of pain in her lower body.  As if on queue, the obstruction glides forward, slithering back beneath the surface.  Rarity gives a sigh of relief as the round knots fade back into the pudgy underside.  She giggles at the soothing feel of stress leaving her digestive cavity.

	Time holds no meaning for Sweetie Belle as the greasy, ribbed passages of her sister ripple around every bit of her body.  Covered in all manners of thick, oily fluid, the tiny unicorn's only source of sanity was the steady beat of Rarity's heart.  She listens carefully for that steady throb among the chaos of the squelching sounds of digestion.  Focusing intently on the even pulse, she slowly slinks through the taut, narrow corridors.  Her body contorts awkwardly around the bends and corners of the slimy tubes as her journey continues without a hitch.  The scentless odor of a starved pony reeks from the fleshy walls as Sweetie sees no waste, even as her trip comes to an end.  With her head pressed against the sphincter of the colon, a cold breeze grazes her head as she waits for freedom.

	“Oh my, what a night of beauty sleep!  I must say I feel ten years younger and two times stronger!”  Rarity stretches out her limbs, yawning widely as her bones pop in relief.  Though she feels absolutely refreshed, something was amiss.  She looks under the covers and around her bed, wondering where the troublesome sibling has gone.  Before she can call out to her, a soft voice calls out to her, causing her innards to vibrate with each word.

	“Rarity... can you let me out please?”  Rarity's eyes shrink at the source of her sister's voice as she takes her chubby belly in both hooves.  The older unicorn stutters in confusion as the familiar feeling of nature calling presses against her hind quarters.

	“Yes... yes!  Of course!  Just, let me go to the bathroom quickly.”  She trots in a haste, feeling the extra weight bounce around inside of her.  Sweetie lays into the slick canopy as she bounces about with each step.  Reaching the bathroom, Rarity eyes the toilet.  She immediately discards the idea of dumping her sister in such an uncivil container as she positions herself over her tub.  The muscled ring anxiously protrudes out as Rarity strains to free her sister.  Sweetie Belle groans uneasily as the colon closes around her tiny frame, shoving her out towards the puckered exit.  Her horn is the first to taste freedom, as the cold air greets the exposed tip.  Rarity gives a macho grunt as excess air violently escapes her rear.  Sweetie Belle's head slowly crowns as the sloppy symphony of Rarity's behind play erratically.  With no energy, the younger sister hangs lazily from the exposed exit as Rarity's anus clenches around Sweetie's lower belly.  Natural lubrication sputter out from within the colon as Sweetie Belle slowly slides into the tub.  Rarity gives one final heave as she expels the long, slimy tail of her sister.

	“Sweetie Belle!  I am so sorry about that I-”  Sweetie Belle holds up a hoof to silence Rarity.  Having her sister's undivided attention, she looks at her completely straight-faced.

	“Rarity... I'm just going to take a shower... can you make breakfast, please?”

	“O-of course!”  The proper unicorn trots out bowl-legged from her recent experience as she politely shuts the door behind her.  The sound of hot, running water follow soon after.
