>you feel something stirring you from your slumber
>something on and around your crotch
>opening your eyes to find the origin of these new sensations, you see two disheveled fillies, one on each side
>Celestia isn't far
>sitting neatly on her haunches, a few feet away in front of you
>Rainbow and the bookworm mirror each other, hooves resting gently on your thighs
>both kissing, paying no heed to how your member was between their lips
>you didn't even have the chance to breathe before you went from a sleepy half-mast to a full raging erection  
>wet, hot tongues snake over your stick as they join mouths
>with both sets of lips moving against each other, sucking on the tip of your dick, the sensation makes your toes curl
>they break their kiss, much to your discontent
>before you can protest, rainbow's wings curls around your dick's tip while Twilight works the base with hers
>their wings are fascinating to watch
>so dexterous and precise
>somehow, they can wrap their delicate, velvet-soft feathers around your shaft
>they’re like feathered hands
>you can't continue the technical appreciation of this due to how good it feels
>the warm duvet of four wings strokes your member in unison, massaging and rubbing every inch of its surface
>your eyes want to roll back, but Celestia catches your gaze
>still sitting, looking at the ground
>she's acting like she wants to be punished for something
>she was paying attention to Twilight the whole day
>you'd get to her soon eno-  
"Oh sweet fuuuuck..." you moan
>on cue, Twilight and Dash speed up their wings’ pace
>you run your fingers in the multicolored mane to your right and grab at the purple hoof on your left thigh
>you can only try to hold on gently as you shudder with pleasure, feeling wave after wave of euphoria
>you end up squeezing a fistful of mane, but it only served to make Rainbow blush
>your hold on Twilight's hoof was light enough, but the shivering contact made her bite her lip
>the sultry look in her eyes intensifies as warm cum ran over her feathers
>you sit back and recover as you feast your eyes over a wonderful scene
>Rainbow Dash leans in over your crotch, joining with Twilight in a display of mutual preening
>Dash pecks playfully at her friend's wing, inciting short gasps of surprise
>she returns the favor with long, sensual licks over the entire length of her pegasus partner's feathers
>the little purple alicorn nibbles at the blue wingtips, making Dash squeak with sudden pleasure
>they roll, intertwined, laying on your bare lap as they fondle and clean each other's wings
>breathing heavily, moaning adorably when one feels the other's gentle teeth straightening a feather, or when a muzzle caresses a wing pit
>you watch your blue pet stroke and clean the wings feather by feather, licking up your semen, red faced and panting
>Twilight wasn't doing much better
>hopelessly wet, her eyes unfocused
>she was getting pretty clumsy
>she laps lazily, nibbling and tugging
>she continues to seek out drips of fluids on the cyan feathers, cleaning it off regardless of how distracted she is
>Celestia is still sitting there, staring at the ground
>you catch her eyes dart up, then back down
>her white coat doesn't hide blush very well
>reluctantly, you push Dash against her little princess
>they both yelp and giggle, resuming their "cleaning activities"
>your eyes linger on their messy manes, glistening feathers and heaving chests
"Little slave..." you coo
>she dares not move, eyes frozen on her front hooves
"I couldn't help but notice that you've been a little distant today,"
>your voice grows lower as you go on, sounding a little dangerous
"Master...  I didn't mean to,"
>you stand in front of her, extending a hand to cup her face and lift her gaze to meet yours
>she looks into your eyes
>her expression is strange
>at first she looks scared, but her eyes are full of desire
"You've been a bad girl, so I'll need to punish you,"
>she nods
>without warning, you slap her hard enough that your hand hurts
"I didn't hear you reply, slave,"
>she winces and cowers
"Yes, Master, please punish me,"
>you hear hoofsteps behind you
"Celestia?  Anon?  What's wrong?" asks Twilight, suddenly worried
>Dash puts a comforting hoof on her withers
"The Princess likes it a little rough, Twilight.  Don't worry about it," she says
>the purple alicorn relaxes
"Oh, okay, I guess...  Can I watch?"
"Sure," you reply, giving her a warm smile before striking her old mentor with the back of your hand
>Celestia stifles a cry
"Mmmmmfff..."
>you turn to Dash
"Oh, be a dear and bring me that bag," you say cheerfully as you yank on Celestia's mane to pull her head down
>your pegasus pet wastes no time
>good thing too, your hand was getting sore
>once the bag is in your hand, you rummage through it while absent-mindedly running your hand down your pet's stomach, lower and lower, giving her nethers a slow rub as a reward
"Thanks," you say, extending your glistening fingers to her mouth
>as your little winged filly cleans her own juices from your fingers, you find what you were looking for in your bag
>a nice leather slapping paddle
>ruffling Dash's mane after enjoying the feeling of her tongue and lips on your hand, you turn your attention back to your slave
>head almost against the ground, she was being as submissive as she could
"Now, where was I?  Oh yes, right around here," you say, bringing the paddle down on her rump
SWACK!
>the sharp sound rings through the library, making Twilight jump
>you bring the paddle down with more and more force, large red marks appearing on Celestia's ass with every blow
>you hear her yelp and moan harder and harder as you slap down on her cutie marks
>Celestia's body rests lower and lower until her chin is against the floor
>she was drooling a little
>tears were starting to run down her crimson-tinged cheeks
>you get a satisfying cry when you swing down, holding the paddle with both hands, and land it right on her firm, curvy buttox
>you grab her mane again and lift her up to her hooves
>she stands, her knees shaving visibly
>the wet, dripping marehood between her legs was twitching
>Twilight and Dash were still sitting next to each other, finishing their preening, watching you and your slave
>Celestia's eyes were locked with her old student's
>the pegasus next to her liked what she was seeing, but Twilight was looking with a different expression on her face
>her sopping wet vagina reflected her expression
>Dash may have been enjoying the show, but Twilight was loving it
"Do you like being watched, slave?" you ask, fist still full of her ethereal mane
>she nods
>you yank her mane as hard as you can, pulling her until she flanks you
>you tisk while preparing another paddle blow to her evidently sore rump
WHHSH-SWAAACK
>you pull no punches
>you almost knock her down with every strike
"Y-yes...  Master..." she moans
>you can see small puddles of her slick fluids pooling between her legs
>you stop your assault on her ass
"I think they like watching you too.  However, I'm not done punishing you, slave,"
>grabbing her mane yet again, you drag her to the nearest wall and yank her roughly against it
>you pause for a second to admire the sight of your slave
>sprawled down in a sitting position, back against the wall, legs opened and displaying all they had to offer
>her wispy, ghost-like mane looked practically ruined, nebulous strands and locks floating wildly
>her wings were also a mess, feathers bunched up and sticking out
>she would need a preening after this
>you smiled in anticipation
"You look horrible,"
>she moves her front hooves to fix her mane and pat down loose feathers
>you slap her across the face with an open hand
"Just awful.  Don't even try, you'll just mess yourself up even more,"
>you slap her again, hearing a delightful little cry of pain and pleasure
"Even your own old student can keep her wings in order.  Pathetic, really.  You should be ashamed of yourself,"
>fresh tears form in her eyes as she breathes in huffs
>you lean forwards, gently placing a hand on her face, caressing her cheek
"Just tap my arms if you want me to stop, okay?" you whisper
“Yes, Master,” she replies, nodding
>you pull back, every last bit of softness leaving your touch
"You're useless, Slave.  You can't even reply properly.  You sicken me,"
>you wrap your hands around her neck and slowly squeeze
>Celestia's eyes open wide with surprise
>she looks alarmed as you squeeze more and more
>her hot breath becomes ragged then cuts off completely
"Such a bad little girl,"
>you feel her chest move, trying to breathe in or out but to no avail
"You're humiliating, you stupid horse,"
>you feel her body twitch and spasm, hooves scraping at the floor
>her neck is warm, the soft, short, furry coat was nice under your fingers
>you can feel her heart beat faster and faster as she squirms, eyes rolling back
>she hasn't tapped your arms yet, but just to be sure, you let go
>Celestia wheezes and coughs, slumping down
>as she recovers, you look back at Twilight
>she's biting her lip and fidgeting in place, sitting in a puddle of her own fluids
"Dash?"
"Yeah, what's up Master?"
"Give Twilight some head before she passes out or something, will you?
"Sure thing, Master!"
>you give her a thumbs up as she dives down to service her friend
"Dash, what are yo-
>Twilight goes bright red
Oh...  Wow..." she finishes, mouth slacking
>you turn back to your white Princess, shaking your head
"Where were we?"
>Celestia coughs weakly
"Punishing me, Master," she replies
>you snake your fingers around her throat again
"Correct,"
>you squeeze once more, relishing in how her cheeks flushed madly
>how her reddened eyes well up with fresh tears
>you love to see her bite her lip and weakly flap her wings
>her lower legs twitch and kick
>her dripping cooch seems to beg for mercy
>behind you, Twilight's heavy breathing was slowly evolving into quiet, short moans
>you breathe in slowly, ecstatic
>your slave's forelegs tap your arms, bringing you out of your little heavenly moment
>you let go as if electrocuted
>she slumps in your arms, taking heaving, gasping breaths
>you hold her as she recovers, petting her untamed mane
"Are you hurt?" you whisper
>Celestia's breathing slows
"No, Master..."
>you smile as you see her look up at you, cradled in your arms
>her flushed face, messy hair, completely wildly feathered wings, and red-rimmed eyes were a sight to behold
>you give her horn a slow, teasing lick
>she stiffens, moaning softly
"More?"
"Yes, master, please,"
>you yank her mane, pulling her to the ground
>crouched over her as she lies on her back, you stroke her coat with your hands, settling back over her neck once more
>fingers tightening again, you hunch down and lick her horn as she bucks weakly under you  
>you lick her horn some more, just to be mean
>you let her get a gasp of air as you let your right hand off her throat
>you then bear down with the other and cut off her airflow before she takes another
>with your free hand, you give her a good slap in the face
>her crimson-stained cheeks are so pretty against her normally white coat, you can't help but smile  
>your attention wanders to Twilight and Dash
>the former is slowly building towards an impressive orgasm, shaking and thrusting her hips rhythmically, hooves on your pet's head, one eye shut, the other staring at you both
>her wings were extended, throbbing with pleasure
>the latter's face is buried between Twilight's legs, head deeply nestled, moving with every lick
>your pet was giving you a nice view of her marehood, wings erected stiffly
>every time you gave your slave a slap, you heard Twilight gasp, her head rocking back as she inched towards climax
>Celestia's eyes start to roll back
>as soon as her hoof touches your arm, you release her
>she’s a mess now, damp with sweat
>dripping with vaginal fluids
>completely exhausted and pent up
>her breathing was heavy and ragged, wheezy with strained effort
>you get off her
>she rolls to her side, looking spent
>you grab the paddle and give her sensitive, scarlet ass an unexpected and very energetic slap
>she cries out, her sharp yelp turning into a moan that carried on for a few breaths
>at the same time, you hear a strained, higher-pitched groan as Twilight cums to her old teacher's punishment
>such a wonderful relationship they have...
>you realize that you've been at full mast for a while, this business with your slave riled you up
>Celestia's wings are in a sorry state, perhaps they require attention, you wonder
"Hmmm...  Look at all these messy feathers.  I wonder who could help you groom them.  You obviously can't do it yourself,"
>the little alicorn was barely conscious, sitting there with that dead look on her face
>completely out of it, breathing slowly
>she didn't even notice Dash lifting her head to reply
"We could help, Master,"
>she nudges Twilight, trying to wake her up from her stupor
"Wh-...  Wha...  What's going on?"
>you smile at your pet
>that must have been fantastic head for that lavender pony to be so far gone
"Come on, Twi, the Princess needs a hoof with her wings,"
>she blushes even harder than before
>the hazy pink tinge on her face hasn't left since this all started, but the suggestion seems to have kicked it up a notch
"Preen...  The Princess?" she says, quietly, looking worried and embarrassed
>you cross your arms, getting impatient
>Dash shoves her unsteady friend into your slave, inciting a scared squeak and a surprised moan
>much better
"Princess...  Here I go..." whispers Twilight
>the sky-blue pegasus joins in, taking the other wing
>the effect is immediate
>Celestia tries to remain stoic, but she's clearly appeased and pleased with the gentle licking and biting
>the nuzzling and stroking of her wings sends her into a limp, blisslike state mixed in with small, jerky moans of intense pleasure
>you rummage through your bag some more, looking for toys to distract your slave even further
>you couldn't let her have it this easy after being such a bad little pony
>without a word, you sit behind her, rubbing her swollen, hot folds to lubricate your hands
>you see her muscles tense up, but she remains quiet
>after coating two vibrators in her fluids, you insert one in her ass and the other in her vagina
>she was unable to stay quiet for that
"M-Master..."
>once your distractions are in place, you walk back in front of her and lift her head up by the horn
>just high enough to put her at eye level with your very stiff member
"Now be a good slave and enjoy your master's treat.  If you stop before I let you, you'll be sorry,"
>Celestia grits her teeth as you slowly rub her horn
>overstimulated in every way, she was on the edge already
"Y-yee-hnnnnnnngg....  Yes, M-aahh... Aaaaahh...  Master,"
>her efforts to remain lucid were gargantuan
>but she replied, and opened her mouth to take you in
>without hesitation, her head plunges forward until her muzzle bottoms out on your abdomen
>you can't her but let out a stifled moan; her mouth was almost burning hot, dripping with saliva
>she started moving her head immediately, back and forth for just about an inch, touching your abdomen with every thrust
>your eyes cross when she starts to move her tongue
>it rubbed you, inscribing circles while maintaining contact with most of your shaft
>her warm, rough tongue's texture was magical when lubricated so generously
>even as she sucked, her mouth retained more than enough saliva to keep your dick completely immersed
>you forget to rub her horn for a few seconds
>even while being assaulted on all fronts, your slave was delivering beautiful head
>her wings twitched weakly, slowly extending, allowing Twilight and Rainbow to clean and align her feathers with more ease
>this only increased the amount of pleasure that her wings were giving her
>your slave's moaning was building up, sending shivers through your cock
>you keep your hazy mind in place, though, and start to rub her horn, feeling the smooth ridges with your lubricated hand
>Celestia's wings were now completely stiff, shaking as your pet and her old student mercilessly and vigorously preened them
>the toys in her orifices pulsed on as you moved your hand up and down her horn
>she tensed as her eyes rolled back, jerking back and forth to remain in motion over your shaft, sucking as if to ground herself through this Equestria-shattering orgasm
>her screams of passion, suppressed by your rod, still rang out clearly through the warm library
>you felt her hot breath over your stomach as she greedily sucked in air through her snout
>front hooves pawing at the wooden floor, she rode what seemed to be an endless wave of ecstasy
>every breath was loud with a muffled scream as she kept cumming harder and harder
>you rubbed her horn with increasing zest, feeling that you were about to blow as well
>her relentless, almost subconscious back and forth movement was taking its toll
>as she moaned over your cock once more, you clamped down on her horn and yanked her head until her muzzle pressed against your abdomen
>thrusting involuntarily as you cum in her mouth, you feel her start to slack
>your head rolls back as you groan, completely stiff with throbbing rapture
>you pump everything you have in her mouth, down her throat, pounding your dick into her with reckless abandon
>you're coming down from this unforgettable high when you feel your slave go completely limp
>uh oh
>you cough and shake your head, sobering up in a heartbeat
"Celestia?" you ask, pulling out
>her eyes weren't completely closed, but her eyes were still rolled up
>her mouth was open, dripping with cum and spit
>wings now slowly closing, no longer stiff and shaky
"Princess?" says Twilight
>you push Dash out of the way and roll the white alicorn to her side
"Celestia?"
>still nothing
"Oh my gosh did we break the Princess?" says Dash
>cradling the limp pony, you check if she's breathing
"She's breathing!" you say, relieved beyond words
>Dash sighs heavily, slumping back down on her haunches
>Twilight still looks mortified
"Is the princess going to be okay?  Did I hurt her?" she asks, wide-eyed, almost frantic  
>you pull out the vibrators from your slave, petting her mane
"She'll be fine, we just went a little overboard..."
>Twilight hovers around the two of you, looking like a worried mother hen while Rainbow slumps contently
>you feel her stirring
"Celestia...  Celestia, wake up," you whisper
>her eyes flutter open
"...  Master?"
>you smile at her
"Welcome back, my little slave,"
>her eyes open in shock
"Master, I didn't mean to stop, I'll continue-
>you kiss her snout
"You did just fine.  How are you feeling?" you coo, holding her against you
>she relaxes, settling in your arms
"Thank you, Master...  That was...  Not in thousands of years have I...  Thank you, Master," she replies, stuttering with awe
>Twilight settles as you two talk, sitting back down next to Dash
>you relax, looking down at your completely trashed slave
>save for her freshly cleaned wings, of course
>you remain like this for a while; enjoying her closeness, petting her mane, stroking her soft, damp coat, and calming down from the day's excitement
>you absentmindedly hear your pet talking
"I would have never pegged you for being that kinky, Twilight.  You were always such a proper pony,"
>she giggles before replying
"I still can't believe we just did that...  Oh my gosh..." she whispers hoarsely
>you could almost hear her going beet red
>Rainbow giggles, squeaking with glee
"You remind me of me when I found out what Fluttershy, Big Mac and Applejack do, sometimes.  Lemme give you a hint: they aren't pickin' apples,"
>you hear a chortled cry as Twilight buries her head in her hooves, saying  
"Ohhh my..."
>Rainbow giggles again
"You're so cute when you're embarrassed!  You know, if you get lonely when the princess isn't here, I wouldn't mind keeping you company.  If that's okay with Master, of course,"
>you give her a thumbs up
"Master, what's that supposed to mean?" she asks
>you facepalm
>no thumbs, right
"Means that I'm okay with it, petbro-Dash," you reply, grinning
>you didn't mind being nice to that little pegasus, she was just friendly however you looked at her
>she winks back, Twilight covering her face once again, quietly saying
"Ohhh deaaar..."
>she really was cute when embarrassed, blushing and messy-maned
>as you stir and sit up, Celestia shakes off her exhaustion
>she gives you a little show, slowly cleaning her front hooves, licking, eyes half-open and locked with yours
>she moves to her wings, going over the few spots that had been disturbed by the last few moments of her sexual adventure
>her horn glows faintly as she cleans her coat and face with magic
>the stains and red marks fade until they vanish completely  
>in a few moments, she was back to her usual self
>clean, not a hair out of place, her perfect mane swaying slowly in a nonexistent wind
>you get up and put a pair of pants on, stretching and scratching your stomach
"Anyp0ny hungry?" asks Dash as Twilight tidies up the room
>hungry?  She has to be kidding.  You're famished
>you're about to ask what would be for lunch when a Spike comes running in with a scroll
"Urgent news from Princess Luna!" he calls, looking worried
>he also has a strange, pale, traumatized expression
>how old is he anyway?
"Thank you, Spike," replies the Princess, suddenly regal
>Spike hands her the scroll and nervously backs away, not looking anyone in the eyes as he leaves the room
>you wonder what's eating him all of a sudden; he used to be a cool little dude
"This is not good," starts the sun princess slowly, a grim look settling on her face
"What's wrong?" asks Twilight
>the scroll magicks its way to her
"This can't be...  Griffonia?  We should leave right away, Princess Celestia,"
>you feel like you came in halfway through a movie
>what's Griffonia
>why is it bad?
"Uhhh... Princess?  Mind filling me in?" you ask
>Dash gives you a strange room when you call your slave "Princess"
>this is usual for you though; official Equestrian business is out of your hands
"The Kingdom of Griffonia has declared war on Equestria, Anon.  I'm afraid I'll have to head to the neutral zone and attempt negotiations,"
>you rear back
>war?
>Equestria's never been at war, from what you've read
>they've had disagreements and skirmishes before
>but war?
>what the fuck!?
"I'll go on ahead and warn my friends, Princess.  Dash, you stay here, I'll go get your Element and teleport it to you,"
>Rainbow nods as Twilight blinks off into a puff of magical sparks
>you don't know what's going on
"I'm comi-
"No!  You are to stay here or go back to Canterlot," she says, her tone firm, loud, and commanding
>she looked much larger now than she ever did before
"Celestia?" you croak, feeling a little incredulous and worried
>you've never even seen her like this
>her expression softens
>she slowly steps towards you, lowering her head until her eyes are below yours
"Anon...  Please, I'm sorry...  You must stay safe," she says, gently nuzzling your neck
>you realize why she ordered you to stay so vehemently as she pulls away
>she steps towards the door
>you are suddenly stricken with a cold dread
>if it wasn't safe for you
>if she was worried that you would be injured
>wouldn't that mean it would also probably be unsafe for her as well?
"Princess!  Wait, you can't-
"We have an agreement!  Do not get in the way of Royal business,"
>the heartbroken look in her eyes made your heart stop
>she's really torn up about this, just like you're feeling a rush of conflicting feelings
>your whining isn't helping her at all; you were hurting her with this bullshit
"Celestia, I just wanted to wish you luck!" you blurt before she can cut you off
>her eyes go wide as her wings settle back down against her flanks
"I wanted to tell you to be safe," you say, stepping closer to her
>you pull her into a warm embrace, hugging her tightly
>with your mouth moving to her ear, you whisper
"Come back to me, love,"
>she gasps softly, her muscles tensing slightly in your arms
>you pull away to see her face
>eyes brimming with tears, she nods slowly and kisses you
>you cup her cheek, deepening the kiss
>as it breaks, you hug one last time
>she leaves wordlessly, without looking back
>you stand there, still shirtless, feeling cold and alone even as Rainbow approaches, her face solemn
"Anon, you okay?"
>you look out the window, seeing Celestia flying off into the distance
"I don't know,"
