[1shot] Twice the Lady (F/F, unwilling pred)

>Day roofie in Equestria
>You are Nona.
>The titular human residing in Ponyville.
“The final answer is no.”
>”You don't have a choice in the matter, darling.”
>And you find yourself at a loss, trapped by the waist-high pony Rarity.
>Though you towered over the ponies in sheer height, their magic and schemes were very much something to be feared.
>Being human, you were void of magic, and only had your skills in conversation to get by.
“I don't care what concoction you had me drink last night Rarity, this is weird.”
>”Nonsense!  Twilight assured me the process was seamless and painless, now you just have to be willing.”
>Groaning, you survey your surroundings.
>The entire floor of the inspiration room was covered by a thin, plastic layer.
>Tied to a chair, your legs and arms were bound by rope, tightly fitted to your limbs to ensure no chance of escape.
>Even shifting your weight in the chair proved fruitless as it was practically glued into the floor.
>Probably magic or something.
>In the room, the only ways out were two windows and a door.
>Too bad you were completely immobile in your current state.
>Nor were you equipped with any tools.
>In nothing but your undergarments, you look to the white unicorn that stared up at you from between your legs.
>She pokes your middle with a sly smile.
>”You were quite ravenous last night dear... do hope you have enough for breakfast, that elixir should be making room in there for yours truly.”
>Your stomach grumbles in response as your tubby middle hung just above your thighs.
>The daily diet of sweets and pastries found their way on your figure, despite the amount of physical labor you did to burn the fat.
>Not like there was anyone to impress anyway.
“Trust me Rarity, hands and fingers and whatever are completely overrated compared to magic.  In the time it takes me to sew a dress, you could easily make 20 more!”
>She puts a hoof over your mouth as she clicks her tongue in disapproval.
>”Oh no no no no!  You're not talking your way out of this Nona.  We both know there's only one way to find out if your claims are true... conjecture is nothing but that!”
>She motions with a hoof behind her, bringing attention to the tub behind her.
>”After all, cannot have this large tub of olive oil go to waste, now can I?”
>You feel your eye twitch as Rarity steps into the tub with gentle grace, slowly coating her body with a slippery layer.
>She shudders a bit as her perfectly-kept coat is slathered with edible oil by her own hoof.
>Faking euphoria, Rarity “oohs” and “ahhs” as she covers every bit of her body.
>You shudder at the pony feigning pleasure to entice you.
>The posh pony gazes at you through her displeasure of the mess that dripped from her body.
>”Now for the Pièce de résistance!”
>She takes a bottle of balsamic vinegar and splashes the black liquid over her body.
>Her coat was dotted with tiny, black specks as she sets the bottle aside.
>With half-lidded eyes, she stares into your reluctant eyes.
>”Don't I look absolutely ravishing, you carnivorous creature?  I'll be sliding down that smooth gullet of yours in no time.”
>Shaking your head with gusto, you talk through sealed lips.
“Nuh uh, no way are you getting in!”
>She only giggles lustfully at your response as she steps out of the tub.
>Oil and fragrant vinegar drip from her body as she approaches you.
>”Oh, I'm not asking for your permission, not anymore at least.  I'm just declaring what I'll be doing to you.”
>She punctuates her sentence by tapping your breast gently, leaving a wake of oil on your skin.
>You stare at her rebelliously, your last method of getting out of this situation.
>Rarity laughs throatily as she stands up on your chair, putting her hind hooves on the gap between your legs.
>”Now, open up.”
>You shake your head, her hoof trying to find a place on your mouth.
>Excess oils drip from her body as she stands over you.
>”Darling, I don't think you understand... when I say 'open up,' I mean...”
>Her horn grows a brilliant blue as your head stays perfectly still, your lower jaw popping open under the magical influence.
>Rarity voice goes raspy for a brief moment before scolding you.
>”OPEN UP... please.”
>Your mouth stretches open painlessly, side-effects of whatever Rarity shot you up with.
>Wide enough to accommodate the pudgy width of the greased up pony in front of you, she places her forehooves in your mouth.
>You feel her pull her hooves back for a moment before sliding them further in.
>”Bleck... well... all for the sake of fashion, see you in a bit darling.”
>Unable to resist anymore, her slick legs enter your throat, gag reflex completely gone.
>She fidgets a bit, seeing that her head is the next to go.
>”...No funny business while I'm in there, got it?”
>You shrug, showing the lack of potential “funny business” you have.
>”Good.”
>Slipping her head in, you feel her horn scrape the back of your throat as it stiffly bends down.
>The sharp, salty tastes swirl on your palette as olive oil dribbles down your chin.
>Her silky smooth body slips neatly between your jaws, feeling your neck fit to Rarity's rounded body.
>As you salivate from the curiously delectable flavors of natural oils flowing over your tongue, Rarity's body rocks a bit to help squeeze into the skin-tight passage.
>The bulk of her tummy lays heavily onto your tongue, forcing it to slip out of your mouth and slither between her thick legs.
>You feel her struggle to fit into the entrance to your stomach, lodged deep within your body.
>Through the stretched flesh, Rarity mumbles out a request.
>”Darling, could you be a more accommodating host and open up for me?”
>Groaning at her complaint, the vibrations throughout your neck jiggle her body as she slips a bit deeper in, her body crammed into the bottom of your gullet.
>You tilt your head up, forcing the mixture that gathered into your mouth towards your stomach as Rarity clenches her hind legs in response, gripping your tongue between them.
>”Nona, please, just open up down here.  It's... it's quite... ohh...”
>Her rounded bottom, lodged deep into your maw bears down hard on your lower jaw.
>You wince as you feel your jaw strain at the force pushing down as Rarity's thrusts increase in pace.
>Before you can murmur out a complaint, you feel the mare shudder briefly before a sweet nectar exploded over your taste buds.
>”Oh... dear... that was quite unexpected.”
>Exhaling hard through your nose in a mix of irritation and relief, you feel the weight of the pony shift deeper into you as you see your stomach bulge out slightly.
>Your breasts jostle about as the eager pony wiggles her way into your stomach, taking advantage of the opportunity.
>Her slippery body slithers easily into you, closing your mouth behind the last of her hooves.
>She kicks out a bit to help propel herself down further, only giving you a headache as she bucks the roof of your mouth.
>Reluctantly gulping down at the last bulges of the fashionista that resided in your throat, you gasp for air as the mass within squirmed for comfort.
>Sporting a decently thick belly, Rarity sat behind the layer of fat, forcing your paunch to bulge out beyond your chest.
>A hoof and snout occasionally appear on the surface of your skin as she made herself comfy within the active organ.
>Your stomach rumbles deeply as you feel it twist and ooze on your meal.
>The potion of unknown origin appears to have accelerated the digestive process as the strong churning sensations within make you queasy.
>You gulp down one more wad of saliva, clearing your mouth of whatever was left.
“Hope you're happy Rarity, because we're going to be here for a while.”
>Through the bubbles and groans of your body, you hear her shout through the padded confines.
>”Of course!  Now I'll be able to see the wonder of your hands myself!”
>A sudden pang of realization dawns on you as you feel your belly throb against the delicate pony.
“Wait... how am I getting out of this chair?  I can't move at all.”
>”Oh.”
>Is all you heard before your greedy guts contracted hard on the pony, pulverizing her into your own flesh.
>Your belly pumps up and down as it ensures perfect liquidation of every bit of the body.
>No longer of solid form, you feel the distant drain of the thick soup into your winding tunnels.
>You blow a strand of your hair out of your face, feeling the heavy weight slowly leave your stomach and course through your body.
>Cravings repressed long ago from living in Ponyville rise up in your mind.
>The warmth of the fresh protein meal gave you a brief high.
>Though not the most traditional way of eating meat, the mix of the mystery elixir and your body's want for meaty nourishment made you salivate at the memory of Rarity's thick body passing through your mouth.
>Your stomach grumbles as you space out in bliss as a creeping sensation consumes your thoughts.

>”Nona?  Equestria to Nona, please respond.”
>A familiar voice shakes you from your reverie, as your eyes lazily search from the source.
>You try to stand, but your restraints were as strong as ever.
>”Not out there darling, in your mind.”
>Shaking your head, you recall today's events.
>At least, you still think it was today.
>The moonlight pouring through the room's curtains certainly indicated that some time has passed.
“How long was I out?”
>You hear her voice echo out in uncertainty.
>”Ehh... maybe a few hours, not sure.  Hard to keep track of time when I'm trying to get a grip on your complex body.  Controlling each individual finger is such a chore, so I gave up.”
>Frowning at her weak response, you sigh.
“So, what now?”
>”Well... we could watch your so-called breasts jiggle for another hour, that certainly kept me entertained while you were out.”
>Your body suddenly hops up and down without your permission, your head bowed down for a full show of your wobbling mammary glands.
“Rarity!”
>”Sorry, didn't know they were so entertaining though.”
>Feeling control return to you once again, you look past your breasts to see your belly back in its spherical glory.
“Uhh... why do I look pregnant?”
>A sinister titter resounds in your head.
>”Well, I have to come back somehow Nona, everypony would be absolutely devastated if I just left!”
“But...”
>Your stomach cramps up a bit as something snaps inside you.
>A gush of vaginal liquids erupt between your loins, spilling all over the chair you sat in.
>Your underwear clings to you as it soaks up the amniotic fluid that spilled forth.
>”Oh!  That's my cue, see you outside!”
“But-”
>A writhing figure arises from your skin as a horn pokes out, in search of the exit.
“Oh sheesh...”
>The unicorn thrashes a bit, your body keeping her close to you as you clench down on the panicky figure.
>A familiar voice pierces your lumpy middle.
>”Nona, I cannot see.  Mind helping me out?”
>Shifting in your seat, you find no way to make this more comfortable for you.
>But the movements within made your heart race.
>Each struggle and kick gave a pulse of pleasure through your body.
>Hardening your abs, you feel her squeak in surprise as Rarity's wrestled with the shrinking confines.
>Her soft hooves pushed out against the muscular walls, the slippery lubrication making it difficult to find the way out.
>You pant as your cervix tightens around the mare, having complete control of her body.
>Drooling in concentration, you shimmy out of your underwear as your plush rear squeaks against the soaked chair.
>Your flower opens up below as you prepare for evacuation.
>In a single motion, your mind lights up with pleasant release as you push your entire weight onto the struggling figure, a second rush of fluids racing forth from your slit.
>The bulges flail about wildly within your pelvis, crawling towards the gaping hole.
>A horn was the first to appear as you rhythmically squeeze the large body out from your own.
>Straining against the large girth of her belly, the crowning of the white middle was heavenly as the rest of Rarity's body slipped onto the messy covers below.
>Blind with pleasure, you look to the ceiling to help gather your mind.
>”Now... that wasn't so bad, now was it?”
>You feel your restraints loosening as your body laid slack against the sticky chair, doused in your own fluids.
“Never again Rarity...”
>”Oh come now, I knew you would like that, you just didn't know it yet!”
>You roll your eyes as you handle your sore wrists, reddened from the bindings.
“Really, how do you know I enjoyed it?”
>She gives a malicious giggle before continuing.
>”I was inside you Nona, I felt that carnivorous spark when my lovely body flowed through you.”
>You blush at her words, reminded of the sheer relief upon incorporating her body into your own.
>A smirk grows across her face as she sees your reluctance.
>”Now now, we don't have to do this again soon, but know that I'm always willing to give my body for a dear friend.”
“I never said-”
>Rarity thrusts her head into your vision, her saucy smile in full view.
>Her voice oozes confidence as she interrupts you.
>”As long as I come right back out, sounds good, darling?”
>You stutter, secretly wanting that feeling again.
“F-f-fine...”
>Her innocent demeanor returns as she back up.
>”Good!  Now if you'll just bend over-”
>Standing up as Rarity unties your final binding, you back up a bit as you almost slip on the slippery floor.
“Woah woah woah!  Why?”
>The unicorn expresses a bit of displeasure as your first action of freedom is to distance yourself from her.
>”I am fresh out of magic, and I am not destroying my lovely home to escape my inspiration room.”
>You look to the door, your only viable way of leaving this place.
>”You see, in order to make sure you didn't escape, I swallowed the key to this room before entering you, and I don't think it followed me back out.”
>Swinging your head back to Rarity, your eyes dilate at her words.
>Seeing the shock in your expression, she giggles behind her hoof.
>”Seems you understand Nona, now, if you'll be most cooperative...”
>Rarity grabs a rubber glove from seemingly nowhere as she pulls up a second tub.
>You clench your cheeks in horror as she inches her way to you.
>”Bend over.”
>She waves her gloved hoof to you.
>”It's going up your ass, darling.”
