Celestia's Relaxing Vacation

Celestia didn't normally call Twilight to her own bedroom. Their nightly play time had always been held in her own room, but tonight Twilight had been informed that Celestia was waiting for her in her own bedroom. Wanting to look nice for her mistress, Twilight tightened her collar and slipped into some black thigh high socks that she had stolen from Pinkie's room. She had quite a large collection of sex toys after having raided Pinkie’s room.

She thought fondly of her friends as she made her way to Celestia's quarters, drawing the gaze of many of the royal guard in the process. She gave a few of them a wink, shook her hindquarters at a few more, but didn't waste too much time slutting it up when Celestia was expecting her. She finally arrived at Celestia's room and knocked softly on the door.

"Your Highness?" called Twilight, "I'm here as you wished."

"Come in, love," Celestia spoke gently from inside.

Twilight opened the door slowly and walked in, trying to strut a bit to look nice for Celestia. Looking about the room, it looked mostly the same as it always had. The one big difference was that Luna's torso was laying beside the bed, fresh cum drooling from the cadaver's pussy. Twilight tried not to stare at it, looking instead at Celestia, who was laying calmly on the bed.

"What a cute little outfit. Come up here love, don't mind Luna," Celestia said, "She's just here to cuddle up to at night and sometimes remedy my morning wood."

"She looks good as a fuck pillow," Twilight tried to gauge the situation, carefully thinking about what Celestia might want her to say. She moved forward as Celestia had asked, crawling up onto the bed and kneeling down to lay on her belly next to Celestia.

"She does indeed," Celestia said, reaching a hoof to stroke down Twilight's back, “And now there is only one Element left to extinguish. I'm sure your torso will look every bit as sexy. As will your severed head in the throne room."

Twilight felt that raw surge of abject horror rising in the back of her throat, like only Celestia could get from her, stuttering, "Y-you flatter me, Princess, I... I am ready to die, to disappear, as that is your wish." Twilight felt her soul wilt, now certain that this was why Celestia had brought her here. There was no escape; she may as well accept her mistress’s will.

Celestia casually moved one of her hind hooves between Twilight's hind legs and rubbed it against her slit. Twilight spread her legs to allow her access. Celestia leaned forward, and Twilight did the same, their lips meeting in a deep kiss. Twilight tilted her head into the kiss, deepening it and playing her tongue against Celestia’s, even as her whole body shivered in fear of what was to come. She pulled back and took a deep breath.

"So," said Celestia, continuing to rub between Twilight's hind legs, "Yes, all of them gone, souls gobbled up. You know what happens now, don’t you."

"You’re going to kill me... extinguish me..." Twilight said in a whisper.

"Mmm hmm," said Celestia, "Definitely so, and I intend to make your death particularly agonizing."

Celestia moved from where she lay, sliding over to cover Twilight. Moving above her, Celestia lay with her belly pressed against Twilight's rump. Celestia placed her forelegs on either side of Twilight's upper half, and Twilight felt a heavy shaft flop out against her behind and begin to rapidly harden. Obediently, Twilight lifted her rump into the air, flagging her tail out of the way and assuming a position with her head down and ass up. She spread her hind legs and rolled her hips back willingly against her mentor's shaft.

"A-after I've had the foal, right?" Twilight asked softly.

"I don't know," said Celestia, "I've started to wonder if you're really worthy of having my foal. I can’t have a disgusting cum rag like you bearing my child; I have a reputation to uphold. I'm sure you understand."

Celestia's voice was kind and gentle, practically cooing her words, the way she got sometimes when she was feeling particularly cruel or aroused. The protection Twilight had assumed she had by carrying Celestia's foal slowly melted, and Twilight felt her stomach sink. Yet she also had to admit, the sudden danger made her pussy go from lightly aroused to sopping wet within a few moments.

Twilight obediently kept her position, and as Celestia's cock tip pressed against her entrance, Twilight rolled her hips back to impale herself onto the thick shaft. Celestia popped inside of her, sinking deep. The princess moaned at the feel of Twilight's tunnel wrapping about her shaft, and thrust forward until her tip bumped against Twilight's cervix. Their hips began to thrust together, the wet sound of penetration filling the room as Celestia pumped in and out.

"You’re going to kill me tonight?" Twilight asked softly, taking a deep breath as she continued to move against Celestia.

"Mmm hmm," said Celestia, "By tomorrow morning I'll be enjoying how your corpse cunt clings coldly around my cock."

"A-and my soul?" Twilight panted, her pussy drooling fluid down Celestia's balls profusely.

"Oh yes, I'm going to gobble it up," said Celestia, "No afterlife for you; by tomorrow your life force will be snuffed out. Oh I'm going to cum into you so hard as I eat your soul."

Twilight's tunnel convulsed around Celestia's shaft as they continued to push together. Her insides rolled up and down Celestia in a smooth milking motion, her body beginning to quiver harder with each stroke. Not all of the quivering was from fear though, it was apparent that Twilight was getting off on being fucked far more than usual.

"Are you ready for the darkness, Twilight?" Celestia asked as she licked the back of Twilight's head, "This is your reward, the only reward you deserve, to die in agony and fade from existence."

"I-I am ready... for whatever your pleasure is... my goddess..." Twilight stammered. “I’ve been a terrible student, I deserve this and more.”

Twilight's movements became unstable, her hindquarters twitching as her entire body shook. The purple alicorn suddenly came hard on Celestia's shaft, juice pouring down Celestia's base and balls and soaking into the blankets beneath them. Celestia increased her motions, and Twilight groaned again, another burst of fluid spraying back as her insides convulsed around Celestia's thick shaft.

"Are you getting off on this?" Celestia chuckled.

"A little..." Twilight admitted.

"Do you know what I'm going to do to you first?" Celestia grinned as she continued to pound into Twilight, her tip beginning to beat at her tightly shut cervix harder and harder.

"Y-you're going to fuck my fetus out of me," Twilight groaned, "You're going to purge it from my unworthy body with your fat throbbing cock, oh please do it! Ram right through into my womb!" Twilight couldn’t believe what she was saying, yet it all seemed so right somehow.

Twilight got her wish. Even as her pussy continued to convulse, Celestia forced her way into Twilight's sealed womb, breaking open her cervix and sending throbs of pain through her. Twilight clenched up her face, but continued to thrust her hips just as enthusiastically, arching her back and rolling her eyes back as if she couldn't stop cumming over and over again. Celestia felt her cock punch through and her tip bumped against the partially developed foal inside Twilight's womb.

"Oh Twilight, I'm going to cum so hard," Celestia groaned.

"Oh yes," cried out Twilight, "Cover that little slut in fuck juice, drench it in your cum. Then you can pummel it to death with your cock and rip its cum covered body out of my womb! Then shove that aborted cum bag down my worthless throat!"

Celestia's whole body tensed up as she sprayed her load directly into Twilight's womb. Her fetus bounced about as the torrent of seed filled her up, soaking every corner of her womb with thick goo. Celestia packed the fuck honey into Twilight, but then her thrusting gradually slowed down, panting. She felt her energy inside of Twilight, groping around.

On the edge of ecstasy, she was able to feel Twilight's soul writhing about. It was powerful, just as she thought it would be, but it was different from any other soul she had tasted. Instead of shrinking away, it pushed itself against her, practically begging her to take it in. It took all of Celestia's willpower to keep from ripping it out outright. Instead, she settled for a few nibbles before pulling back. To her surprise, Twilight’s soul followed, practically throwing itself into her, so eagerly that Celestia barely kept from consuming it whether she wanted to or not.

She yanked her cock back from Twilight's cervix, her horn glowing as magic filled Twilight's body. The fetus was protected with a shield and a healing spell, and her womb was resealed. Afterward, Celestia's hips came to a stop, panting as she looked down into Twilight's eyes.

"That's right! I--I... your Highness?" Twilight blinked and looked back up at her mentor, ceasing her own hip movements as well, "Um... did I do something wrong?"

"My faithful student, toy, and lover," said Celestia, "I am afraid I have lied to you just this once, but you have proven your obedience to a fault, and now I'm going to give you something in return."

Twilight groaned as Celestia extracted her cock, her body reshaping itself into her natural form as she pulled herself from atop Twilight. In turn, Twilight's body reshaped itself into a thick sheath and throbbing shaft. Twilight flinched, then looked up into Celestia's eyes with a look of confusion on her face.

"I don't understand," Twilight was a bit slow when she was horny.

Celestia rolled over onto the bed, laying on her back and spreading out all four legs. She waved her tail about her smooth slit, and beckoned Twilight with a single hoof.

"Don't keep me waiting now," said Celestia, "That's a fully fertile shaft hanging between your legs, and I'm quite in season; you don't want to waste this chance, love."

Twilight moved cautiously towards Celestia, still panting from her unquenched arousal, her fresh shaft standing at attention beneath her. She stepped up to Celestia, leaning downward and breathing deep at her mentor's waiting slit. She slid her tongue from below the slit, over the drooling lips, and then up Celestia's belly. Shaking with excitement, she didn't want to waste too much time on foreplay. Instead she continued to lick up Celestia's body until finally her belly was above Celestia's, her shaft throbbing between their stomachs.

"I'll even let you talk dirty to me, in fact I insist," whispered Celestia, then placed her hoof gently to Twilight's nose, "Just. This. Once."

"Y-you ready for this, you royal s-slut?" Twilight tested, caught off guard by Celestia's unique requests.

"Mmm, yes," said Celestia, "Ram that fertile cock womb deep, my little stud."

Twilight pulled herself back and lined up her tip to Celestia's slit, eagerly pushing against her lips. Celestia was tight thanks to her tendency to heal everything; had Twilight not known better she would have thought Celestia hadn't been used in years. Her whole body tensed at the heat as she penetrated the slickened tunnel, feeling Celestia's lips roll over her shaft as she pushed deep. Thanks to the size of the breeder she had been given, her tip bumped against Celestia's cervix well before she was ball deep.

"Oh you're so wet," panted Twilight, "You're so ready for me to knock that slick fuck hole up aren't you?"

Twilight groaned and enjoyed the feel before pulling back and beginning heavy thrusts, slamming herself against the entrance to Celestia's womb and gripping about her flanks with both forelegs. Celestia leaned forward and they two kissed deeply once again, saliva dripping down their chins as they lathered their tongues together. Twilight pulled back and renewed her thrusting, slowly forcing Celestia's womb open, and then finally feeling the tightness of her cervix around her cock tip. Twilight lunged forward again, her belly finally slapping against Celestia's as her tip prodded the back of Celestia's womb.

"You like that fuck spire rammed ball deep into your cum sucker?" Twilight became more confident as Celestia allowed her to speak as she wished, "I'm going to give you just what you want, whore goddess." The feeling of power from being allowed such a thing was incredible, almost more arousing than the sex itself. Twilight now understood a small bit of how Celestia must have felt.

"Yes, fuck that royal cunt," said Celestia, "I'm just a cum bucket at heart, I want you to swell my belly with your hot fertile spunk."

Twilight tried her best to hold out, wanting the moment to last for as long as possible, but that was a tall order as Celestia's pussy rolled over her cock so expertly, centuries of experience making her a master at milking when she wanted to be. Celestia responding to her words drove her even further, balls seeming to tighten up as Celestia's tunnel rolled up and down her pulsing shaft, pre drooling from the tip. Twilight gritted her teeth, trying desperately to hold on.

"I'll... fill that... cum trap... oh fuck I'm gonna cum so hard," Twilight muttered between clenched teeth, "You whore... I bet you've had... more cock than Pinkie." Of course that wasn't difficult to have done at Celestia's age.

Celestia grinned, "Oh many times more. I lost track of that long ago." She leaned forward and whispered, "But you're the first one I've ever allowed to impregnate me."

"Oh fuck yes... get ready for my load, I'm gonna knock your whore cunt up!" Twilight screamed.

The surge of sperm was so large that it almost hurt. Twilight flooded her foal juice deeply into Celestia's womb, swelling Celestia's gut to be as large as Twilight's already was. It overflowed as Twilight continued to pack more cum in, splattering out around the penetration and pouring down Twilight's thighs, drooling off her ball sack. Twilight's body spasmed as she continued to cum, finally collapsing once she was done, limp atop Celestia's body.

Celestia casually pushed Twilight off of her to the side, Twilight's body separating with a slurp and cum pouring out of her impregnated pussy. She rolled over onto her belly, stretched out, and spread her hind legs once again.

"You're not done yet are you?" asked Celestia, "The whore goddess isn't sated yet."

Twilight grunted as she came back to her senses, pulling herself up to all fours again, legs shaking but shaft still rock hard. She excited moved back to Celestia, pulling her front hooves up onto Celestia's ample plot as she slid herself back between Celestia's legs and smacked her cock against Celestia's behind. Celestia flagged her long tail up and wrapped it about Twilight's neck affectionately.

"Y-you want that cock in your tight whore ass?" panted Twilight, "Well you're gonna get it you pregnant bitch."

Twilight stuffed her tip against Celestia's rear entry, but Celestia was intentionally clenching it as tightly as possible to make Twilight work for it. Work for it Twilight did, straining and gripping about Celestia's behind until she finally popped herself inside. Moaning as she forced her way deeper into the clenched tunnel, she managed to force her way until her balls swung forward and smacked against Celestia's drooling cunt. Celestia loosened up once she was in, and Twilight began to rapidly thrust into her mentor's behind.

"You like that up your plot hole, you cock-woshipping nympho?" Twilight moaned, "Beg for me to cum in that ass!"

"Oh frisky," Celestia grinned, "Please cum into my tight ass, cram me full of fuck juice; I'm your cum bucket now."

Twilight couldn't have held herself regardless of what Celestia said. So stoked from what she was being allowed to do, she blew another load even faster than the first one, blasting Celestia's guts full, swelling her up once again. She grunted and gripped Celestia's behind, rolling her eyes back and groaning out again. After packing her seed deep, her hindquarters slowly ceased again as she began to slump atop Celestia once again.

"Yeah..." panted Twilight, "That's a... good slut..."

Celestia shrugged Twilight off onto the bed once again, watching her collapse onto her side with a happy grin on her face.

"Well I hope you enjoyed yourself," said Celestia, "Now go back to your room. I want to spend some quality time alone with my sister
