“So what is this about?” said Celestia, following Gilda into the hallway and closing the door behind her. “If it’s as serious as you make it sound, then-”
Celestia’s voice went abruptly silent - and so did her mind, as the collar clasped around her slender white neck. Gilda slowly lifted her talons away from Celestia, backing away nervously as she waited for some kind of reaction from the princess.
The thin black collar could easily have passed for ordinary. It was entirely unadorned, just sturdy black material with a metal clasp. If the castle guards had searched Gilda or Greta at the door, the presence of the collars they’d each hidden in the folds of their dresses wouldn’t have been too difficult to explain away - although it probably would have seemed strange that neither griffon was actually wearing the collar they carried with them.
Gilda wasn’t actually sure that the collars would work on a Princess. She was pretty damn sure that the pair of collars she’d found were the genuine article, ancient relics of immense power… but Celestia herself was also an ancient relic of immense power. The collar was supposed to be able to control anybody, but if it didn’t work… Gilda would have a lot of explaining to do, and very quickly.
But from the way Celestia was standing motionless in the hallway, it certainly seemed like the collar was working. With a slight quaver in her voice, Gilda broke the silence and issued a command. “Take me to your bedroom, princess.”
“Yes, mistress,” said Celestia, her voice entirely emotionless. She led the way down the long white halls of Canterlot Castle, her high heels clicking against the bare tile.
Gilda’s heart raced. It worked! It was working! No sign of resistance from the princess - Gilda quickened her pace so that she was walking beside Celestia, and peered at her face. Her expression was - well, not blank, exactly, but perfectly calm. If the “real” Celestia was trying to fight the collar, it didn't show.
They passed a handful of guards on the way to Celestia’s bedroom, but Celestia nodded to acknowledge them in a way that seemed to allay any suspicion. When she arrived at her chambers, she pushed the door open, permitted Gilda to enter, and followed behind her.
And then she just did nothing again, having no command to follow. Gilda tilted one arm downwards, letting another hidden item fall from the sleeve of her dress. She caught the little vial in the talons of one hand, flicked off the rubber stopper, and downed it in one gulp.
The flavor was familiar: the taste of bitter weeds masked poorly by blackberry. She wasn't drinking the magical potion for the taste, though; she was drinking it to expand her sexual horizons. She and Greta had gotten in the habit of using this potion to enhance their playtime, and the prospect of using it with a princess was irresistible.
She could only get it from pony merchants, though, and so it was a big, thick horsey cock that was currently growing from just above her pussy. But she'd gotten used to that; the look and feel of a pony dick was pretty natural to her at this point.
And since she was already turned on, the dick was already stiff as it began to grow. It made itself known, even from beneath her dress, as it tented up the plain white fabric. Celestia’s eyes drifted down as she perceived movement, but they drifted back up when the growth stopped.
Gilda was a little disappointed. Her cock was a foot long and thicker than her wrist; it was impressive, damn it. But then again, she hadn't ordered Celestia to be attracted to her yet…
“Celestia,” said Gilda, “I'm the most beautiful girl in the world. You're in love with me, and you, like, love everything about my body.”
As soon as Gilda was done speaking, Celestia let out a long, breathy sigh, her pale white cheeks flushing red as she gazed at Gilda. “Oh, my love, my mistress” said Celestia, “please permit your servant a single kiss. I would do anything for you, I would do anything to touch you just once…”
“You're gonna do a lot more than that,” said Gilda. “Strip, princess. Show me everything.”
“N-no!” said Celestia, and Gilda jumped back in shock. But Celestia began to pull her dress from her shoulders - slowly, giving Gilda a bit of a striptease - and let it drop to the floor. Celestia posed her body, thrusting her round snow-white breasts and tossing her shining hair.
Gilda felt her cock jump, releasing a drop of milky Previn that stained her dress. Every time she gave herself a dick, the damn thing was always so leaky… well, whatever. It was time for her to strip too. She pulled off her dress and tossed it away, leaving herself nude. Gilda may not have been the most beautiful girl in the world, as she'd ordered Celestia to believe. She wasn't even the most beautiful girl in this room, since the perfect Alicorn body of Celestia outshone her easily. But she wasn't bad to look at; she had an athletic build, with powerful legs giving way to a big, round feline rump.
“Hmm, how should we start?” said Gilda. “How about you lick my big kittycat butt, princess?” She leaned herself over the bed, wrapping her hand around her cock and raising her ass in the air. “Really get in there, your highness. Show me you love every part of me.”
“No, I will not-” there was anger in Celestia's voice, but by the time Gilda whipped her head around to look, the princess was calmly approaching her, looking hungrily at Gilda’s furry brown butt. She knelt, working her muzzle between Gilda's cheeks, and then her slick, warm tongue was circling the griffon’s anal ring.
Gilda had never had her ass eaten like this before. With other girls, there had been hesitance - making it clear that they'd rather have been doing something else. But Celestia was absolutely devoted to Gilda’s asshole, pleasuring it as if she loved it more than anything in the world. Gilda stroked her cock as Celestia's tongue probed her hole, feeling more pre leak from the wide, flared tip.
Celestia was too good at this - Gilda felt herself draw close to orgasm, and released her cock from her hand. “Okay, princess,” she said, “how about you lick my pussy?”
She rolled over, presenting the slick cunt at the base of her freshly grown dick. Celestia was all over it instantly, tickling her lips and flicking at her engorged clit. This time there was no resistance, no sudden flash of anger -although Gilda was still wary that it could happen again. Was Celestia’s resistance weakening as she followed Gilda’s commands… or was it getting stronger? Gilda couldn't yet tell.
Gilda gave her cock a few long, slow strokes as Celestia ate out her pussy. She was still dangerously close to coming, and she was going to blow her load all over Celestia’s beautiful wings if she didn't go easy on herself.
Then again, her magically grown dick did have the ability to cum multiple times in pretty quick succession. She figured she might as well ease some of the tension by cumming in Celestia’s mouth. “Okay, princess,” said Gilda, moving her hand down past her medial ring. “Blow me.”
Celestia raised her head, bringing her lips toward the head of Gilda’s cock - but conflicting emotions began to flash across her face. “No,” she said, “I… I don't want to… I won't, I…” but she opened her mouth wide and embraced the head with her lips, and soon she was giving Gilda the best BJ of her life. That nimble, busy tongue was gliding in circles across the flared tip, licking pre from her slit… and then her head was descending, her mouth swallowing up more and more of Gilda’s inches, until the princess finally kissed the griffon’s fat medial ring.
All the while, though, her eyes were shifting between panic and anger. She seemed to be trying to stop herself from sucking cock, but she couldn't. The collar’s control kept her on task, no matter how hard she fought. Gilda was of two minds: if she broke free, that would be a disaster. But seeing the pony princess literally unable to resist her cock was pretty fucking hot.
And Gilda was finding herself unable to resist cumming. She'd been horny all night, fantasizing about dominating Celestia, and now that it was happening, she couldn't held herself back. Her cock, halfway down Celestia’s throat, throbbed and gurgled and erupted, shooting a load right into her belly.
And as her cock shot that first jet of griffon seed, Celestia’s demeanor abruptly changed. She pulled her head back, suddenly panicked and angry - but taking her mouth off Gilda’s cock resulted in the next shot of cum hitting her right in the face. “I will not... “ she said, feebly lifting her arm to try and grab at her collar - and although it shouldn’t have been difficult for her to reach it, she didn’t seem to be able to get her fingers close enough. “Remove this collar, Gilda, or… or…”
Her face still splattered with Gilda’s jizz, she glared down at the griffon, her chest rising and falling with deep, angry breaths. Gilda was still mid-climax, kind of getting off on Celestia’s anger. But as the last of her load dribbled down her erect shaft, she had to admit that the princess’ resistance presented a problem.
“Shh, shh,” whispered Gilda. “You love me, remember? You don’t gotta be all angry, babe.”
Celestia looked confused. “I love you? I…”
“Yeah, baby,” said Gilda, sitting up on the bed. “Gimme a kiss…”
That humble request didn’t seem to trouble Celestia’s mind. She leaned in, pressing her lips to Gilda’s beak, meeting the griffon’s tongue with hers. The kiss seemed to be calming Celestia down; she didn’t object with Gilda went for her tits, squeezing them her her talons and softly raking the skin with her claws. So big, so round, so heavy…
“I just got an idea,” said Gilda, pulling away from the kiss. “How about you give my tits a little kiss too?” She hefted her left breast with one hand, offering it to Celestia. The princess knelt by the bed and, calmer now than before, only hesitated a moment before bringing her lips to the tip of Gilda’s breast.
“Mmm, good,” said Gilda. “Now I need you to do something else for me.” She paused to bring her other hand to the crown of Celestia’s head, running her talons through the princess’ long, flowing hair. “Drink. I want to feed you, Celestia. I want you to drink my warm, sweet tit milk… you need to relax, and, like… bond with me. So drink.”
Celestia went from kissing to sucking, and soon Gilda felt a warm trickle from her nipple as the milk began to flow. She let out a happy, satisfied moan as Celestia suckled her, feeling the rhythmic tug from Celestia’s suckling mouth. The princess’ body began to relax; her shoulders had been tight since her last outburst, but now every muscle was loosening. The taste of Gilda’s milk seemed to be pacifying the princess, making her resistance fall away - and when Gilda told her she could stop, Celestia looked up at her with nothing but love in her eyes.
“Gilda, my love, my mistress, thank you for sharing your milk with me. The taste of your body is heavenly…”
“All right, sounds good,” said Gilda. “And you’re not going to get angry anymore? Not going to fight me?”
“No, never, never,” said Celestia. “I love you, Gilda, you’re everything to me… I’ll never say anything that could hurt you ever again.”
“Awesome,” said Gilda. “This calls for a celebration.” She fell back onto the bed and spread her legs, beckoning for Celestia to join her. “Mmm, never scissored with a princess before…”
Gilda’s cock, even after her climax, was still standing straight up - so when Celestia interlocked her legs with the griffon, there was nothing preventing their pussies from meeting in the middle. Celestia gasped as their lips touched; now that she wasn’t fighting back against the collar, contact this intimate sent a wave of ecstasy through her body. She began to roll her hips, grinding against Gilda, stroking the griffon’s slick, soft pussy lips with her own.
“Gilda,” gasped Celestia, “I… want you to love my pussy, I want to make you feel good…” She ground her hips deeper, and their clits touched, making them both whimper in surprise. Celestia followed up with movements that brought their clits rhythmically in contact, growing more precise and confident with each shift of her hips. The griffon and princess both squealed louder with every touch of their sensitive flesh, and when they came, they came together, spilling fluid onto the fine white bedsheets of the royal alicorn.
“Shit,” gasped Gilda. “Pretty fuckin’ good… but it’s not over till I cum in ya. Get on this cock, Princess.” She held the base of her dick, pointing it skyward, and Celestia straddled her, positioning her dripping pussy just over the flared head of Gilda’s cock. Celestia bent her knees and let her body come down onto Gilda, embracing the thick flare with her pussy and sliding down its length.
“Oh, that’s good pussy,” moaned Gilda, as Celestia slid past her medial ring. “The scissoring wasn’t bad, but shit… this is what pussy is made for. Take it all, princess… and ride me hard.”
“Of course, mistress,” said Celestia. “I can’t wait to feel you cum inside me… once my marehood pleasures your magnificent cock, I’m sure that you’ll want to do it again and again…”
Gilda grinned. Even though “her” cock only existed when she took a magic potion, it was still nice to have it complimented. “I bet I will,” she said.
Celestia was uncommonly tall, with wide, juicy hips - but even she had a bit of a hard time getting all of Gilda’s cock inside her. It took a little bouncing to get herself around the wide base - and once she started bouncing, she didn’t stop. Her pussy, slick and so wonderfully tight, glided up and down Gilda’s shaft as the bed creaked underneath them.
Gilda felt confident in her control now, but she was actually kind of overwhelmed. Celestia was tall, statuesque, with assets that jiggled beautifully with each bounce of her bountiful body. She was also powerful, practically a goddess - and with her resistance extinguished, she belonged entirely to Gilda. And damn, she could fuck. Gilda was going to need a lot of dick-growth potions… maybe some that lasted longer…
“Fuck,” grunted Gilda. “I’m gonna cum. Gonna… shoot a fuckin’... griffon load deep in that princess cunt. You want that? Wanna get a pussy full of my spunk?”
“Yes, yes,” cried Celestia. “I need everything you can give me, Gilda. Feed me, feed my mouth, my pussy, give me cum, give me loads and loads of your wonderful cum…”
Celestia came, still bouncing on Gilda’s cock as her pussy spasmed and clenched around the thick shaft. “Fuck-” grunted Gilda, feeling her cock throb violently. “Gonna cum-” Another load pumped upwards, splattering into Celestia’s cunt - and leaking out of her pussy as she bounded up and down.
“Oh, I can feel it,” cried Celestia. “Your cum! My mistress’ cum, my mistress’s love, oh Gilda… Gilda, Gilda…” She collapsed onto Gilda, laying her body atop her new lover. “Please, Gilda, never leave me…”
“Sure thing, sweet cheeks,” said Gilda, grinning triumphantly. “Let’s get going, we should meet up with Greta…”
“All right, Moonbutt,” said Greta, slapping Luna sharply on the ass. “You’re all mine now.” She blew out a short breath. “Really nice bedroom, by the way.”
“Thank you, mistress,” said Princess Luna.
“Hm, mistress,” laughed Greta, flicking the collar around Luna’s neck with one talon. “I could get used to that. “Especially since you’re gonna be my big blue slut from now on. How about you show me those royal tits and that alicorn ass?”
Luna pulled away the straps of her dress and pulled it downward, slowly peeling it away from her body. Midnight-blue tits bounced into view, succulent round delicacies topped with nipples of darkest indigo. When Luna pulled the dress past her hips, Greta knelt behind her, clasping the princess’ ass with her talons.
“Damn,” said Greta. “Like damn. This is a choice ass, princess. Just wanna snuggle up between those big beautiful cheeks…”
“I can locate shrinking or enlargement spells that would make that feasible,” said Luna, her voice still eerily absent of emotion.
Greta raised an eyebrow. “Uh, I was bein’ figurative,” she said, “But… put me down for a solid ‘maybe’ on tryin’ that out sometime.”
“Yes, mistress.”
“Hey, can you… y’know... loosen up?” said Greta. “I need you to be sexy for me, and you’re kinda… stiff. Oh, that reminds me!” She stood, and shook the vial from the sleeve of her black dress and drank the contents, wincing at the bitter taste. As her cock began to grow, she circled Luna, showing off the growing bulge that lifted the fabric of her dress.
“Stars above,” said Luna, biting her lip, “You’ve given yourself a stallionhood. Look how it grows…”
“Totally, totally,” said Greta. “It’s a horse dick, too, so suckin’ it should come natural to you. You’re old as balls, right, princess? You sucked a lotta dicks over the centuries? Lotta stallions been up in them guts?”
“I…” Luna’s expression, which had been doing a passable job of looking “sexy,” suddenly darkened. “My… sexual history is… is not… you…” She stumbled, as if lightheaded.
“Woah,” said Greta. “Are you fighting back? Shit. Kinda hot, but… could be a problem.” She lifted her skirt, letting her cock flop out, and pulled the whole garment up over her head. “Just sit down on the bed and take some deep breaths, okay? Try to relax.”
Luna seemed to calm down slightly as she took a seat on her bed. “Good,” said Greta. “I can help you loosen up, okay?” she took a seat beside the princess. “You want to relax, right? You want to feel good?” She put her beak next to Luna’s ear. “You want me to finger your pussy… don’t you?”
“Yes, m-mistress,” said Luna, parting her legs.
“Of course,” said Greta. She laid her hand on Luna’s thigh and slipped her talons lower, until the knuckle of one finger brushed against Luna’s clit. The princess shivered, drawing in a long, shuddering breath - and since greta hadn’t ordered her to speak or move, all she could do was sit there and let Greta’s talon go deeper. Another finger, and another, joined the first, probing Luna’s slick depths.
“Mmm, nice and wet,” said Greta. “I command you to get real slick and horny for my big griffon cock.” She stroked her shaft, feeling Luna’s fluids wash over the talons of her other hand. “Ooh, you’re gettin’ excited now… maybe you wanna take a taste of my cock, princess? Get your mouth around it before I stretch out that royal pussy…”
“Yes…” whispered Luna, slowly bending at the waist. “Yes… mistress…” Her body shifted uncomfortably, and she hesitated as her mouth descended towards Greta’s cock… but eventually her trembling lips touched the flared tip and began to envelop it.
“Ohhh yeah,” groaned Greta. “Me and Gilda like to play with each others’ cocks, but beaks can’t do the same job as a nice wet pony mouth. All night long I’ve been hearing ponies talk... but this is what your mouths are really good for.”
Luna slowly worked her face lower, taking more of Greta’s inches into her mouth. She was grunting, struggling, already gagging on the thick pink shaft. “Mmm, much better than talking, don’t you think, Moonbutt?” said Greta. “I’ve heard how you talk when your mouth isn’t full of cock. You’re all thees and thous and shit, right? Cuz that’s how everybody talked back when you went psycho and your sister had to slap the shit out of you…”
Greta laid her hand on the back of Luna’s head, pushing her further down onto her cock. “But now that you’re mine,” said the griffon, “You can just be my good little cocksucker. You don’t gotta worry about goin’ crazy again, you just gotta suck when I tell you to suck... and open your legs when I wanna nut in that tight princess pussy…”
Luna began to sound out muffled words, her mouth still stuffed with cock. Over time, the words grew louder - but not clearer - and Luna’s expression began to twist in anger. “Woah now, Luna,” whispered Greta, “Relax, okay? Just focus on sucking… and get ready for a big salty load.” She stroked Luna’s starry hair, pressing down firmly on her head. “You got nothing to be angry about, okay? You love having my cock in your mouth… and my cum is your favorite food… and I’m gonna give you a lot.”
“Nnnnmmmgghhh,” groaned Luna, pushing back against Greta’s hand. She struggled weakly at first, but she seemed to grow stronger - and the hair beneath Greta’s talons became darker and colder. Growling, Luna pulled her mouth off of Greta’s cock, pushing her hand away and springing off of the bed.
Luna stood before Greta, her body fighting itself as she glared at the griffon. Greta raised her hands, trying to placate the princess, but there was more than mere anger in Luna’s sudden defiance. Her cutie mark, the pitch-black sky, expanded across her body, bathing it in pitch-black from head to toe. Her horn lengthened, her wings grew sleeker, and her mane spread into a loose, flowing drift of stars. Nightmare Moon had returned.
“Woah,” gasped Greta, standing from the bed. “Chill out, chill out. Holy shit…” he presence of the nightmare tyrant was intimidating to be sure, but Greta couldn’t help but notice that Nightmare Moon’s bust and ass were better than Luna’s. Rounder, thicker, jucier. Whatever magic transformed Luna into her shadow-self, it had also granted her desires for a bigger, more beautiful body.
“We will not chill out, you iniquitous… chimeric… slattern…” grunted Nightmare Moon. “We are the nightmare itself, and you are a beast… devoid of magic…”
“Okay, wow,” said Greta. “First of all, the first part of that? Didn’t understand a word. And the second part… I got enough magic to collar you, princess.”
Nightmare Moon growled, raising her hands to her neck. “This trinket is not a match for one such as I…” her fingers plucked at the collar, unable to get a grip on the metal clasp. “When I am free, I shall reserve the deepest… darkest night for you. Your fate will be a nightmare unending…”
“Looks like you’re having a hard time getting that collar off,” said Greta, approaching the princess. “How about this? I order you not to remove the collar.” Nightmare Moon’s wrists went slack - but she fought her way back to control, and her hands found the collar again. “I command you to look at my big beautiful griffon tits.” Nightmare Moon continued to fumble at the collar, but her eyes stared at Greta’s pert breasts. “I fucking decree that you are imagining what my tit milk tastes like… your mouth is watering…” Greta put her hand underneath one breast, lifting it invitingly. “You’re a ruthless conqueror who takes what she wants, and what you want right now is a taste of my milk.”
“You cannot tell me what to do, mortal…” hissed Nightmare Moon. She opened her mouth, then paused, as if trying to remember something. “You… you will stand still, I command you to stand still while I drink from your breast…”
Greta cackled. “Sure thing, Nightmare Moon,” she said, grinning. “I’ll do whatever you want. You’re a big scary nightmare horse, I don’t wanna risk pissing you off. You just latch onto that little pink nipple and drink your fill, big girl…”
“Yes, I shall,” said Nightmare Moon confidently, kneeling and closing her lips around the tip of Greta’s breast. It had been a long time since Luna had suckled at a breast - longer for her than for most ponies - but it felt natural to lick and suck and feel the first drops of warm, sweet milk hit her tongue. She wrapped her arms around Greta, pulling her closer, and slowly filled her mouth with milk.
“Mmm, it’s good, right?” said Greta, reaching down to stroke the alicorn’s wings. “I think you’re gonna like being my bad little slut. You can be as angry as you want… use as many old-timey insults as you want… but you’ll always do what I tell you to. You’ll be mine forever, Nightmare Moon.”
Nightmare Moon kept suckling for a time, although anger began to show on her face. She swallowed, a lump descending her throat, and then she pulled away from Gilda with a sigh. “Damn you,” she muttered, lowering her head. “Curse you…”
“Mmm, nice,” said Greta. “I can put up with a little anger from my sexy little pet…” She flopped onto the bed, her cock waving back and forth as her body bounced on the mattress. “Feel free to call me whatever dirty names you want, Nightmare Moon… just as long as you hop on my cock.”
Nightmare moon, her face twisted in anger, approached the bed. “You have no right to issue orders to us…” she fumed. “You are beneath one such as I…”
“That’s the idea, babe,” said Greta, grabbing the base of her cock and waggling it mockingly. “I’m beneath you, you get on top and ride my dick.” Still grumbling, but not slowing, Nightmare Moon crawled onto the bed and lifted her hips up above Greta’s cock. “Mmm, that ass is even better now,” said Greta. “You got thick in a hurry when you went all evil.”
Nightmare Moon, now straddling Greta, slammed her pussy down onto the griffon’s shaft, taking the first four inches in one forceful motion. “My physical assets do not require your approval,” she snapped, working her hips lower. “I will… pleasure myself on your member and hopefully you will cease your abuse for a time.”
“Mmmph, maybe,” said Greta. “Ride me hard, babe… but don’t be too rough.”
Grunting in anger, Nightmare Moon worked her hips lower, taking more and more of Greta inside herself. “Rrrgh, you are so damnably thick…” she growled, working her way past the medial ring. “Your cock stretches me so…”
“Ooh, you know how to flatter a girl,” said Greta. “Tell me more about how it feels to have my cock inside you, baby.” She reached up to squeeze Nightmare Moon’s ass, pinching the black, furry cheeks between her talons.
Nightmare Moon scowled, not wishing to flatter Greta - but she couldn’t resist a direct order from the griffon that collared her. “It fills me,” she hissed. “My marehood grows wetter just at the thought of it, and its touch is… ecstacy… I despise you, yet I cannot stop myself from plunging your magnificent cock deeper and deeper into my divine cunt…” She finally hit bottom, taking the last inch of Greta’s cock into her pussy. “Oh, stars above…”
Gasping and whimpering, Nightmare Moon lifted her body and slammed it back down. “I need it,” she moaned, pawing at her tits with desperate, groping fingers. “Your cock, I need it, I cannot stop myself… please, you must… never release me… I cannot live without your cock…” She began to bounce on Greta’s dick, bringing her hips slapping down onto Greta’s pelvis with each bounce of her statuesque body.
“Damn, you’re heavy,” gasped Greta, astonished at how much Nightmare Moon was making her bed bounce. “Those big round tits and that thick ass… that’s a lot of mare… Shit, you’re gonna make me cum, girl.. You want that? You want me to shoot a big griffon load all up in your pony pussy?”
“Yes,” growled Nightmare Moon. “Yes, you vile, worthless creature… release your seed. Breed me, order me to carry your foals, fuck me every night… degrade me until I shriek with rage…”
“Fuck, oh fuck, you are perfect,” moaned Greta. “My big angry fuckdoll, so pissed off about how much she likes gettin’ fucked… hates me... but loves... my dick…” Greta’s body spasmed, and her cock shot its first jet of cum, splattering the thick load against Nightmare Moon’s cervix. “Cum for me,” ordered Greta.
And Nightmare Moon came, her cruel voice crying out, her legs kicking against the mattress. The walls of her pussy milked Greta’s spasming cock, greedily filling her love tunnel with the griffon’s seed. It was the biggest, best climax of the princess’ life, a gift to her body from the collar that controlled her. And when it was over, she fell forward, feeling completely fulfilled but helplessly weak.
“Aw shit,” whispered Greta. “All right, five minutes of cuddling, then we gotta meet Gilda in the courtyard and fly on outta here. She is gonna flip when she sees I collared Nightmare Moon…”
