Twilight shivered and attempted to roll over but the bottom half of her body did not follow the commands her brain sent. Confused and still half asleep she looked down to figure out what the problem was. The moment her eyes opened however, she remembered the previous night and realized the sensation she was feeling was Celestia’s still massive cock wedged inside her. A blush rushed to her face as she saw how big her belly had gotten. She poked the massive cum filled organ with a hoof and watched it shift and slosh around.

“I’m sorry dear, did i wake you?” Twilight turned or at least tried to face Celestia. Realizing that was impossible she looked over her shoulder to see Celestia’s magic providing the illumination she thought was from the sun.

Twilight shook her head. “Just cold,” she shivered again and scooched her body closer to the larger alicorn who in turn wrapped her legs around her. Apparently the blanket had vanished somewhere during the night.

Celestia was surprisingly warm despite the door to the balcony being open, letting the cool morning breeze in, a fact that Twilight enjoyed immensely as she nestled in as close as she could get. Celestia moaned softly as the movement was enough to remind them both of the fact that they were still locked together for the time being. Twilight smirked and ground her hips down, shifting and moving the huge cock still resting inside her. Her moans intertwined with her lover’s, drawing the attention of more than a few passing guards.

An alabaster hoof pressed firmly against Twilight’s mid section ceased her teasing. “Be still for a moment.”

Twilight frowned and did as she was told. After a few moments, Celestia’s magic slowly faded and she breathed a sigh of relief. “Raising the sun may be second nature but i think you just made me raise the sun a few seconds early.”

“I am so sorry, princess, i was just…” her excuse died off as she noted Celestia’s relaxed muscles. “I should apologize to Luna, i wouldn't want her to think that something malicious had happened, especially so soon after her return.”

“Oh she will be by shortly, my dear, you can tell her then. In the meantime though i'm sure you have a few questions and i need a moment to recuperate for that matter.”

Quill and parchment appeared from nowhere, summoned forth seemingly by Twilight’s unbridled curiosity forcing the universe to bend to her will. Celestia cocked her head, noting the fact that it didn't seem as though Twilight even used magic at all to summon the writing implements. Celestia prodded Twilight with a hoof. “Ask away, my pet.”

Taking the hint to stop worrying and start asking, Twilight cleared her throat. “My first question would have to be, how long does alicorn mating usually last compared to the average pony?”

“Well as you know pegasie mate the shortest, their mid air courtship rituals have fallen out of favor the past few hundred years but their short mating periods are remnants of those old rituals. Unicorns as you know you know are in the middle of the spectrum of mortal ponies, although many have forgotten or lost the unicorn kamasutra. Which is a crying shame, as to make love like the unicorns of old was ...” A shiver ran up Celestia’s spine, drawing a moan from the other princess currently on Celestia’s dick. Her magic flickering as she made notes despite the sudden rush of pleasure.

“You get the point, their finely tuned nerves necessary for casting magic make them have somewhat of a hair trigger. Lastly are earth ponies, as you have no doubt guessed my astute pet-” her said pet shivering in delight at the comment, making sure not to ruin her notes while she did so. “-they last the longest due to their hardiness and connection to nature. I am sure you will find this interesting but earth ponies have the oldest religion in equestria based around a fertility goddess.”

Leaping at the opportunity to speak between Celestia’s thoughts, Twilight politely cleared her throat and continued only after she was sure she was not interrupting. “Is there a reason you are giving me this much background information?”

Twilight felt the telltale twitch in Celestia’s cheek signifying her awkwardness. “Well, Twilight, for one thing raising the sun is more taxing than you might think. Sol isn't a morning being, ironically,” Celestia snorted in irritation. “And you should know by now what I’m like when I give you your special, private lessons.”

Twilight blushed and nodded. “Sorry to interupt, please go on.”

“Well as you know we are the embodiment of all three tribes, however this doesn't translate to our biology, oddly enough. Before you ask, i don't know why and my own experiments have been limited to myself, and such a small sample size does not a good study make,” both princesses shared a giggle before Celestia continued. “From my understanding, ancient alicorns ruled mixed tribes and ruthlessly fought amongst each other for dominance. I won't go into anymore detail but suffice it to say that the rule shared by Luna and myself was a break from the norm, as standard the affair back then was to fight the other potential ruler to the death. Or take them as a brood wife.”

Celestia shook her head, her mood souring slightly. “As you have no doubt noticed, Luna defers to me despite us being officially equal and although i have tried to mend this it always seems to crop back up later. Her thoughts are that since i am the eldest that she should defer naturally to me,” Celestia brought a hoof to her lips stopping her train of thought. “My apologies but i am rambling again. Ahem, as you can tell we alicorns subconsciously submit to a stronger alicorn usually - but not always - based on age,” Celestia looked out the window suddenly caught up in a thought.

Twilight furiously took a few more lines of notation before gently squeezing the white leg that lay draped over her. “I must ask you, Twilight, did you purposefully usurp Cadence to take her position within our hierarchy?”

“I uh, what?”

“Ahh, so you did so subconsciously. Interesting…”

“I did what?” Panic clear in Twilight’s voice.

“Don't worry about it, Twilight, i can feel my strength returning so we will wrap this lesson up here. As I mentioned, alicorns seem biologically predisposed to struggles for domination and this spills over into love making as well, I’m afraid. The long time it takes for the ‘male’ to finish as well as the female’s resilience are a result of this constant battle for domination and submission,” Celestia relaxed slightly, her voice shifting out of the one she normally only used during lectures. “Any questions?”

“Um, no, your highness,” Twilight’s pen worked furiously, filling another page before turning to the next and renewing its mad pace for nearly the entirety of the next. All the while Celestia began to tense up slightly, evidently feeling a little forgotten about although she did not air this feeling.

Her notes finished, Twilight nearly yelped when she leaned back against her lover only to find some Celestia’s muscles tense. “Oh, mistress, I’m sorry, I wasn't thinking,” Twilight slowly pushed herself down against the cock still buried inside of her grinding herself against the larger alicorn’s crotch. All the while withdrawing her grasp on the legs encircling her, holding her own tight to her chest making herself smaller.

Celestia’s tension slowly melted away, however only doing so completely when she felt her pet kiss up and down her exposed neck. Each kiss was a mere peck, soft and quick, as she reaffirmed her place beneath Celestia. Finally relaxed once more, Celestia held her pet tightly and hummed her approval.

“Good morning, Tia, lady Twilight,” both alicorn’s looked over to the balcony in front of them where Luna stood smiling. Shaking off the morning dew, she yawned exaggeratedly.

Twilight’s body tensed up and shame burnt across her face, unsure of what to do. She waited for Celestia to say or do something. When Celestia’s hips thrusted up into her she buried her face in her hooves and moaned softly.

“Good morning dear sister, we must apologize for shortening your night a tiny bit. This one did not make concentration an easy thing to do.” Celestia thrust powerfully at the end of her sentence making Twilight squeak suddenly.

Luna’s laugh though genuine, was marred by exhaustion and she looked down at the floor shifting from hoof to hoof. Celestia rolled her eyes. “Do come in, dear sister.” As her sister walked in, Celestia picked up Twilight’s back left leg allowing her to thrust harder into her pet’s sopping wet cunt. “How was your night?”

Luna’s initial confidence waned somewhat and she seemed to want to say something however found herself staring at Twilight’s massive cum filled stomach that shook with each deep, powerful thrust. Swallowing to force herself to focus she spoke in a trembling tone that quickly filled with confidence. “It was interesting … but we will talk more about that later, when you are not indisposed.”

Twilight found her curiosity overpowering her shame and she looked up at Luna in an attempt to figure out the source of the older alicorn’s trepidation. However all she found was a strange musty smell assaulting her nose. It was of rain and burnt ozone found after a lightning strike. It was a strange turn from Celestia’s soft flowery smell she seemed to ooze at all times. She was so captivated in her thoughts that she didn't notice Luna getting closer.

Celestia slowed her thrusts and eyed her sister curiously. “Do you need something else, little sister?”

Luna cleared her throat and straightened her posture before speaking. “I would like to use your concubine at the earliest convenience.”

Twilight froze. It wasn't that crazy of a request, one she would fulfill if Celestia willed it. Something told her it was not her place to speak now, so she merely studied the moon princess closely. Noting her powerful aroma and the drooping cock hanging between her back legs. It was far smaller than Celestia’s, and dripped a small but steady stream of precum. Twilight unconsciously licked her lips and made a note to ask about why Luna’s endowments were so much smaller than her sister’s.

Celestia’s lips curled into a snarl. “Maybe sometime in the future,” and from her curt tone and use of the term ‘little sister’ instead of ‘dear sister' it was clear to Twilight that Celestia was reasserting herself. She felt small and insignificant as both alicorn’s stared each other down. After a few tense seconds, Luna lowered her head and stepped back. Celestia’s dismissive snort allowed Luna’s head to rise.

Twilight desperately wished she could take more notes. Luna bowed slightly and moved to leave. “If that's what you wish, Tia,” as an afterthought she stopped in the doorway to the hall. “Just don't forget to open court for your replacement.”

“What do you... oh pony feathers,” Celestia cursed and mumbled still worse ones under her breath.

Luna giggled and left the room quickly, calling down the hall as she ran. “Sorry I can't help, I’m just too tired. Good morning, sister!” she exclaimed, her voice fading into the distance as she ran down the hall.

“That cheeky little,” Celestia laughed deeply. Slowly it petered away leaving her shaking her head. “Well i guess we will have to go open court today since my dear sister is already no doubt locked in her room, asleep.”

“Wait a second do you mean we- eep!” Twilight’s question turned into a squeal as suddenly Celestia stood up, carrying Twilight with her. “What are you … ?”

Twilight’s body was encased with the glowing aura of Celestia’s magic making her squirm. To be touched with her magic was like a being caressed by the soft light of the mid afternoon sun. Warm and relaxing, it reminded Twilight of laying in the sun with a good book. She became instantly thankful that such relaxing thoughts came to her mind as Celestia was apparently not finished. Gripping her pet tighter, Celestia twisted the smaller mare around until the two were facing each other. Twilight squirmed and was barely able to tuck in her legs so as to avoid hitting Celestia as she suddenly found her muzzle inches from her mistresses’.

Twilight’s legs instinctively wrapped around Celestia’s barrel, holding them close. All the while the cock resting firmly inside of her shifted and moved, causing both mares to moan in pleasure. Celestia’s magic held them firmly together while it split and grabbed the blanket from her bed and wrapped it about them both. With the blanket tied firmly, Celestia cast a simple spell to make sure the knot wouldn't come undone and looked down at her hoof work. Twilight rested securely against her barrel, her upside down face twisted in ecstasy as her body shook.

“Comfortable?” Celestia’s voice was thick with arousal and a hint of determination.

Twilight nodded, her stomach groaning slightly as it's distended mass was squished against Celestia’s stomach.

Celestia trotted around the room doing a quick circle. Twilight could do nothing but push her face into the neck of her mistress and bite back the waves of pleasure assaulting her mind. The enormous cock firmly wedged inside of her shifted dramatically with each step hitting another part of her abused pussy. Celestia nodded in approval and before Twilight could regain her senses she found herself being carried into the hall to the sight of two very amused guards.

“Wonderful morning, your highness.”

“Off to open court, your highness?” The second guard who looked far younger than his counterpart cocked a curious eyebrow at the odd sight the two tied together mares made.

“Yes we are. Day off or not it seems,” with a curt nod Celestia cantered down the hall, hardly noticing the twin salutes of her guards.

Twilight meanwhile had her face buried in her mistresses’ neck hoping to not attract any undue attention the already strange sight might bring. Celestia seemed nonplussed by the entire thing and walked around as if it was business as usual despite the fact that her cock was buried inside a mare currently tied to her barrel in broad daylight.

On the way down to court they passed the usual assortment of castle staff. Guards nodded greeting, maids bowed low and concubines not currently in the harem gawked and silently burned with envy. Twilight would have usually basked in the attention as those mares and few stallion were for the most part a jealous lot and she enjoyed the fact that she was Celestia’s favorite immensely. Just as they rounded the final bend and with the courtroom door visible at the end of the hall, a familiar pair of ponies walked in from an adjoining hall.

Twilight shrunk and silently wished she could become invisible but that's not what Celestia wanted so she reasoned she would just have to deal with the embarrassment that facing Rarity and her own mother would bring. Celestia was silent throughout the entire walk save for a few polite greetings - although this initially worried Twilight immensely. It was as if she had done something wrong, there was something about the way she walked and moved that told Twilight she was biting her lip and trying to hold back. While she distracted herself by analyzing her teacher, she heard the calm voice of her mother break those thoughts.

“Hello, your Highness, i hope my Twilight has been treating you well,” her tone was even and calm but anyone who knew her well could hear the pride barely hidden behind the polite voice.

“She is the perfect cocksleeve, Velvet, you should be proud,” Celestia’s words aroused Twilight and filled with shame in equal measure.

She shrank closer and ground her face into her mistress's’ neck, hoping to hide in her fur. “What brings you to the castle so early?”

Although her voice was polite, everypony knew better than to tary on politeness when commanded directly by the princess. Rarity stepped forward first, speaking a bit too quickly before she reigned in her nerves. “I am here because I was joining Pinkie Pie at court before I intended to spend the rest of the day at my boutique here in Canterlot. However, after I met this dashing young mare on the street and I’m afraid we got terribly carried away in our conversation.”

Twilight Velvet shrugged. “I was hoping to get a new dress for a dinner party later tonight that I’d forgotten about, when I happened upon Rarity. I knew that the stars had aligned.”

Celestia considered them both quietly, putting on an air as if they were being analyzed and studied. In reality she was merely holding back a laugh as she noticed that the similarities between mother and daughter were more than skin deep. How many times had she had to calm Twilight down after she’d forgotten about something after her studies had caused time to slip between her hooves.

Celestia’s chuckle dispelled the air of tension she had created moments before. “Sounds like fate favors you today. Be daring, they say,” Celestia’s wink made Twilight Velvet’s cheeks flush at the sight. “We shouldn't tarry long I’m afraid, lady Velvet, lady Rarity,” Celestia nodded at them both in turn.

Twilight silently thanked her mentor for saving her from further embarrassment, only for Rarity to ruin that. “Oh, darling, when will you be back in Ponyville?”

Twilight’s voice was so tiny from embarrassment and speaking into Celestia’s neck that she might have been able to beat Fluttershy in the quiet game.

“I didn't catch that, what did you say?” asked Rarity.

“By Tuesday.”

“Well, when you are back be sure to come see me as soon as possible!”

All the while Twilight hid her face against Celestia’s neck, her legs squeezing her mistress tighter as her embarrassment mounted. Celestia mercifully turned away and strode towards the court doors fending off any continued attempts at conversation by the talkative fashionista. “Thank you.”

Twilight’s muffled voice was inaudible to everypony other than the one it was meant for, who merely smiled and nuzzled the smaller mare as much as the awkward position allowed. As the pair waited for their arrival to be announced and the guards to open the doors for them, Celestia leaned down and whispered. “Do not be so scared, my pet, have we not done something similar before?”

Twilight blushed and hid her face further, her mind forced into reliving all the times Celestia had commanded Twilight to service her while in the middle of court. Or in a side room during a recess, or during the middle of a speech. By the time the doors creaked open to reveal the throne room itself Twilight had to admit to herself that she had loved all those times - this time was just a little more strange than usual.

Right when Twilight concluded that she had a handle on the strange state of affairs she found herself in, and was once more enjoying herself, her reverie was dashed the moment she heard Pinkie Pie shout “Hi, Princess Celestia! Hi, Twilight! Nice cock sock, your majesty.”

“Why thank you, Pinkie Pie, are you all ready for your day in court?”

“You betcha, princess!”

“Wait, what? You can't be serious, mistress! Pinkie pie is ...?” Twilight gaped as she turned an upside down look at the pink mare who was not only serving in court today but actually donned the golden throne and sat there quite contentedly. Twilight’s mouth opened and closed like a fish gasping for breath.

Celestia didn't seem to notice and strode confidently across the courtroom to stand beside the throne, positively beaming in pride. The gathered ponies of court all looked on in equal parts awe and confusion. Twilight’s brain still reeling from the news making her unable to do anything other than gape.

“I would like to thank my little ponies for gathering here today for a very special day court. First off, i would like to assuage any fears you may have,” Twilight noticed this part of Celestia’s speech seemed aimed at her. “Only matters concerning parties have been lined up today, as all other matters have been handled by the night court,” Twilight and a considerable amount of the gathered nobles let out a sigh of relief. “Without further ado, I officially hoof over temporary ownership of the throne to lady Pinkie Pie,” Celestia nodded her head at the party pony who grinned from ear to ear and saluted proudly.

Before Celestia turned to leave, she made brief eye contact with a non descript noble Twilight didn't seem to remember. The princess and her cock sock left before the nobles had even a chance to begin whispering amongst themselves, saving Twilight some embarrassment. As soon as the heavy doors closed behind them, Twilight grabbed her princesses’ head and forced her to look down. “Are you sure about this, mistress? Pinkie pie isn't exactly…”

“She's exactly what I need,” replied Celestia. Before Twilight could even begin to ask her to explain, she found the two of them being carried through a servant's door and down the less populated and more narrow halls used exclusively by the castle staff. Celestia’s tense muscles robbing Twilight of the ability to speak for fear that what she said would be out of place.

Once out of earshot of most ponies, Celestia cleared her throat. “I must admit something to you, Twilight. I am not exactly the best with parties,” she whispered. Twilight cocked her head, confused. “This may sound strange coming from me, but I’m not exactly the most social of ponies.”

Twilight gasped - Celestia’s ability to speak in front of a crowd in addition to writing amazing speeches were the stuff of legend. As if reading her mind, Celestia looked down at the mare who she was using as a cum dump. “Speaking in public is easy as it's a simple matter of looking up over the gathered ponies and speaking to the horizon. Luna always handled this type of thing, but now it seems as though in her brief time back in equestria she has garnered a reputation for being a loner,” Celestia snorted. “Which couldn't be further from the truth. That’s exactly why I got our good friend Pinkie to take over.”

Twilight mulled this over and was forced to admit that her plan held merit, despite the fact that it still included making Pinkie Pie a regent of Equestria. Had the mere idea been presented by anypony else, it would have reduced her to tears, though whether it would have been due to laughing or crying Twilight wasn't so sure. Sighing inwardly, Twilight admitted defeat and placed her hooves back around the barrel of her mistress.

Walking in silence, Celestia smiled widely the entire time. Only after Twilight heard the sound of cutlery did she even think of asking where Celestia was taking her. “Is that ... the kitchen?” Stuffed full of potent alicorn cum in her womb and stomach, Twilight wouldn't be hungry for days but something about the chance of chef Ram Seed’s cooking was not an opportunity she could refuse.

Twilight groaned as her legs were beginning to feel numb. Celestia seemed to pick up on her distress and double timed it past the castle personnel in order to pop her head into the kitchen. Once inside she snagged an enormous piece of a passing cake, the attendant carrying it was shocked and looked like he was about to say something. But Celestia pressed a hoof to her lips and disappeared back out through the door. The attendant merely looked around for a second to see if anyone else saw what he had. Noticing that no other pony had seen it, he merely shrugged and kept going as if nothing had happened. With her prize in tow, Celestia and her cock warmer quickly ascended a set of hidden stairs in order to get back onto the floor with their rooms, only for a strange voice to call out from behind them.

“Not running away from me are you Celestia?” Celestia rolled her eyes and Twilight grimaced, they knew that voice anywhere.

Turning around reluctantly they both met the amused glance of Chrysalis who had stuffed a muffin into her fanged mouth. Celestia sighed inwardly and put on her mask of politeness. “Funny meeting you here Chrysalis.”

The changeling snorted and quickly swallowed what was left of her food. “It certainly is, isn't it?” The changeling and the princess of the sun exchanged an odd look that left Twilight confused. “But I might as well take advantage of this bit of serendipity so i may have the chance to properly thank your cock warmer for all her help.”

Chrysalis’ genuine smile disarmed Twilight of some of her mounting ire, which disappeared entirely when her pride in servicing her princess bubbled to the surface. “You’re welcome Chrysalis. I was more than happy to help any allies of Equestria,” her prideful smile marred somewhat by it being upside down.

“Oh no, you misunderstand me. Tokens of appreciation from a changeling always take a physical component as such I present to you a boon in the form of a spell that I would like your permission to cast upon you,” the changeling queen’s tone was honey-sweet and although Twilight was sceptical, she doubted she sensed sincerity in Chrysalis’ voice.

“What does it do, exactly? Princess, is this allowed?”

The sun princess seemed to roll the idea around for a few seconds, shifting her hooves and Twilight from hoof to hoof. “I don't see why not. Chrysalis is an ally after all, I'm sure she would never do anything to endanger a friend,” she finished the sentence with an icy tone and equally icy glare leveled at the changeling, who - despite what she would claim later - was genuinely intimidated even for but a moment.

“Of course not,” Chrysalis scoffed.

“Then you may cast your boon upon my cock sock,” she said, as the pride that welled in her voice made the shame burn from Twilight’s face.

The changeling smirked at the description and lit her horn. After a few seconds gathering power, she leaned forward and touched it to the space between Twilight’s eyes. This required her to bend in an awkward angle and was only made possible by changeling flexibility. The instant Twilight felt the horn touch her forehead a rush of power ran through her like a jolt of electricity. Only where real electricity flowed from one point to the ground this seemed alive in it's intent. It lingered on her eyes, burned along her spine and seemed to sit momentarily at her breasts and pussy before disappearing.

With practice garnered over centuries, Celestia held back a moan as the writhing mare impaled on her cock twisted and turned. Twilight had no such experience. “Oh, Celestia, Aaaa,” she groaned, as the pleasure twisted and changed. She dragged out Celestia longer and longer until she realized the state she had been reduced to and quickly closed her mouth. The cock lodge inside her stopped twitching a moment later allowing Twilight to think.

“You ponies are not nearly as prudish as we thought,” observed Chrysalis. When both mares who were currently copulating in broad daylight turned back to the changeling queen, they saw a rare blush across her face. A moment later it was gone but both observers couldn't help but realize that they seen a rare sight.

“Now, if you'll excuse me, I was hoping to gorge myself on the ambient love but I seem to be full already,” Chrysalis continued. The changeling pressed a hoof to her lips, a wisp of green smoke rising from within.

Not waiting for either mares to respond, the queen simply turned and left, holding her stomach with one hoof. Twilight turned up to her lover. “Did she look a little … full to you?”

Celestia tapped her chin and smiled. “She was positively full to bursting.”

Twilight squinted, making out the changeling queen as she squeezed past a servant at the end of the hall. Her large distended belly making this act difficult, forcing another belch from the changeling’s lips.

Both mares turned to each other and giggled quietly at the silliness of it all. The faint wisp of hunger that Twilight had felt when she realized that she’d had the chance to taste the much lauded chef’s cooking had disappeared. The only thing currently on her mind was Celestia.

Celestia looked down at her concubine with a strange look in her eye the second they stopped giggling. Twilight couldn't place the odd feeling that burned in her breast but a moment later she didn't have to give it any further thought, as the pink lipstick-covered lips of her mistress gently pressed against her own. Suddenly she was lost in an ocean of pleasure as Celestia’s hips pressed forward slightly grinding against her own. Twilight could do little but grip her mistresses’ barrel and hold on. Parting her lips when Celestia’s insistent tongue overcame her meager resistance.

For a while that's where they stayed, locked together in the middle of the hall. Servants passing by, most not even batting an eye at the strange pair fucking in the middle of the hall. Celestia pressed her tongue deeper, holding Twilight's tongue down as she her hips ground harder making the poor mare - already lost in pleasure - moan in ecstasy, her mind little more then swirl of lust and devotion.

After a few minutes passed, Twilight could feel her mind finally clear enough to form a coherent thought that didn't begin or end in how much she loved her mistress. Smiling stupidly her tongue roamed around her mouth looking for Celestia’s, but coming up empty. She looked up at Celestia who was merely looked forward. All around her she could see ponies pass by, catching glimpses of the sky as they passed windows in the hall..

Dimly aware of the distance traversed, the only thing on Twilight’s mind was the cock resting in her womb. It was all that mattered, she reminded herself. The only thing in the world worthy of her attention other than the rest of Celestia. Whilst inwardly giggling, she managed a frown. Celestia’s graceful gait ensured she was hardly ever jostled even though she lay between all four of her legs. Twilight’s frown deepened as she realized how little she had attempted to ensure Celestia was properly pleasured, and in that moment she forgot Celestia’s desire to hold back until they were alone once more and begun to thrust back against the penis resting so deeply within her.

She felt Celestia’s chest muscles tighten somewhat and - misinterpreting that as a move to keep going - Twilight did just that. Clenching her inner muscles and gripping the larger alicorn tighter, Twilight rocked back and forth, working the huge shaft inside her until she could feel Celestia’s walk become slightly more awkward. Burying her face in Celestia’s neck Twilight took a deep breath, catching the alicorn’s scent and moaned loudly, forgetting the presence of the other ponies entirely.

Twilight heard somepony speak, but it hardly mattered. Listening didn't have anything to do with pleasuring the cock she loved more than anything. Her legs tightened and she swung herself back and forth violently, the thin fabric holding them together drawing loose under the alicorn’s furious thrusting. Twilight slowed her pace, panting and moaning as she ground her hips down. Feeling the massive cock head press against the back of her womb brought a fresh moan to her lips. Moments later she could feel herself cumming, taking all of her willpower to not thrash around. She gripped Celestia’s barrel tighter and pressed her lips against her mistresses’ neck over and over again.

When her orgasm finally died down, she noticed they were no longer moving. She shrugged to herself and started to work her inner muscles once more, only to feel an aura of magic suddenly overtake her. Her thrashing did little to dampen the magic that surrounded her. Slowly she felt herself being removed from the cock she so desperately craved. A pathetic whimper escaped her lips as her hooves reached out, trying to pull her closer.

Slow as to very nearly feel cruel, she felt Celestia’s perfect dick escape her until with a resounding pop she felt it finally slip free from her cunt. “No, please goddess above, don't take it out,” whimpered Twilight pathetically. She fought against the aura frantically, desperation pouring onto strength that she didn't realize she had.

“Twilight, calm down,” her mistress commanded. Celestia’s voice was firm and absolute, but the smaller alicorn still pawed at the floor and whimpered. Rolling her eyes Celestia lifted her hoof and lightly smacked the smaller alicorn across the face.

All at once Twilight stopped her mewling and placed a hoof to her cheek in shock. Suddenly realizing what had happened she looked up at Celestia with tears in her eyes. She tried to say something but the tears came faster then her thoughts could. Celestia’s calm and forgiving tone rescued her from the tears about to cascade down her cheeks. “Shhh, Twilight, it's okay. It was just Chrysalis’ spell. It was a little too much for you,” she said, as she leaned down, her hoof reaching forward and carressing the smaller alicorn’s cheek. “It's okay.”

Swallowing hard and wiping away her tears, Twilight choked down her sadness and looked back up at her mistress. “What happened?”

Celestia’s serene and smiling face was marred with concern, making a fresh wave of concern rise within her pet. “You got a little overwhelmed and made for an interesting walk back to our room,” responded Celestia. Her soft and gentle smile worked wonders on Twilight’s sadness.

Twilight’s eyes could no longer hold the gaze of her mistress, shame burning across her face. “But I came without permission and … and ... and,” she stumbled. Celestia’s hoof stopped her train of thought before she could start crying again, gently running across Twilight’s chin.

“Yes you did, and you are partially forgiven. I will punish you accordingly in a moment, my dear pet,” she suggestively mentioned. Celestia’s honeyed words and gentle tone made a shiver run down Twilight’s spine despite the fact she had displeased the only pony she could ever love.

Sighing softly, Twilight took a deep breath and steadied her internal turmoil. “Yes, mistress. What would you have me do?”

“Rise little one and go put on the clothes and makeup i have set out for you.”

Twilight rose obediently and picked up the clothes that sat on the bed without looking, and scooping up the makeup in her magic while she trotted into the attached bathroom. Celestia closed the door behind Twilight using her magic.

Once alone, Twilight stood there staring at the cold floor while a mascara stained tear ran down her face. I really fucked up this time, didn't I? Desperation flooded her mind and for a moment she stood there breathing hard and trying not to panic. Slowly subduing those thoughts she stood up with determination in her breast. Celestia gave me an order, I can beat myself up later. She looked into the mirror and grimaced. Her eyeliner had formed long blackish lines down her face, carried by her tears. Her lipstick hadn’t fared any better and was almost completely gone.

Frowning to herself, she wiped it all away with her magic and turned to the bundle of makeup which she grabbed without looking. The usual black lipstick was there but also a few other hues and colors. Twilight gasped and barely resisted the urge to do a little dance, the amount of time and effort her mistress had put into the little package striking the young mare.

She put the rest of the makeup aside, quickly turning her attention to the clothes she hadn't checked out yet. They looked like a bundle of black lace on the ground. After she picked it up in her magic, she blushed so large that it covered her face. There were stockings that covered her legs from hoof to hip but also a lacey vest-like thing that would stretch across her barrel. Putting it on quickly, she turned to the last object which looked like a veil of some kind. It matched the rest of the black lace perfectly. Putting it aside to put on last, she grabbed all of her makeup once more and turned to look at her reflection. I will look perfect for Celestia. With thoughts of her mistress fresh in her mind, she went about applying the makeup exactly how she knew Celestia liked.

In the other room Celestia frowned and shifted her weight around on the bed. Everything felt uncomfortable, especially the clothes she wore. They were too … she looked down at the yellow and pink lace covering her hooves and neck. She fidgeted uncomfortably, unsure as to whether or not she should remove them. However her thoughts quickly turned to her pet who had been in the bathroom for quite a while now. Thoughts of her pet made her still hard cock twitch and a fresh wave of worry ran through her mind. Had she been too harsh? Not harsh enough? She squashed the idea and turned back to the bathroom door just in time to see Twilight.

Twilight stood awkwardly in the doorway, shifting from hoof to hoof, as Celestia stared at her. Twilight wore slight eye shadow complimented by the twinge of blush she wore and renewed Lipstick. The pièce de résistance was the immaculate way she had curled her eyelashes with the same color as the lipstick. Twilight’s eyes drew Celestia’s own to her like a moth to flame. She could not look away, nor did she want to. Twilight looked back at Celestia and opened her mouth without speaking, silently asking permission to speak. Celestia merely nodded, not even bothering to close her own gaping mouth.

“Is everything alright, mistress? I can change if you don’t approve?” Twilight turned, intending to go back into the bathroom. Celestia pulled her around with her magic and brought her skidding across the floor until they were muzzle to muzzle.

Insistent lips pressed against Twilight’s own, to which she eagerly submitted. Celestia leaned forward, extending a hoof to roughly slap Twilight’s flank, making a moan escape from Twilight’s lips. She felt her mistresses’ hoof grope her backside as her tongue pressed into her mouth. Twilight was lost in a sea of pleasure until she felt Celestia’s large, dominant tongue withdraw from her mouth and the hoof on her flank disappear. She held her eyes closed until Celestia’s lips finally pulled back from her own. With great reluctance she opened her eyes to find Celestia’s inches from hers. Twilight’s first reaction was to look down and avoid eye contact but there was an insistence in Celestia’s eyes that she dared not refuse to meet.

“I am sorry, Twilight, but I must punish you now. Do not worry though, little one. You will enjoy every minute of it,” whispered Celestia huskily. Twilight shivered as her own barely contained lust made her quiver in anticipation. Celestia used words like ‘punish’ quite a bit, but in her experience it usually meant doing nearly the same thing Celestia always told her to do - just minus the politeness. Something about Celestia’s brutal domination made her even wetter than dressing up so sluttily had already accomplished.

Rampant desire clouded her judgement. Twilight looked Celestia up and down, defying her instincts which told her to look down and avoid eye contact. However the instant she looked upon her mistress in all of her perfection, she was glad she resisted that urge as Celestia positively radiated beauty and … Twilight didn't understand, as Celestia was the most beautiful being that had ever existed and every moment spent with her was spent realizing just how perfect she was but now she was different.

In place of usual fetlock regalia, she wore pink and yellow lacey sock things. Twilight couldn't find a word for them. They weren't stockings like hers, as they looked thicker. They were still lace, so they couldn't be socks. Shaking such thoughts from her head she noted the ribbon Celestia wore at the base of her tail, very much akin to the to the black bind she wore around her own tail to ensure it wouldn't get in the way if Celestia decided to mount her. More amazing still was the fact that her black lipstick kisses hadn't been cleansed from Celestia’s perfect white fur making her usually immaculate coat seem a little out of place. But finally the slight pinkish eyeshadow and look of pride she wore seemed to suggest that Twilight’s kisses were left there on purpose. Twilight very nearly melted as her blush become intense. Only the insistent and questioning eyes of her mistress kept her in check.

“Mistress Celestia you’re ... you’re … Perfect!” exclaimed Twilight, her tone filled with reverence. She very nearly fell to her knees at the sight.

Celestia’s smile must have borrowed some of the power of the sun, for she lit up the room and allowed the light to spread to Twilight’s face, the instant she looked upon it. There was a hint of pride there but it was drowned out by the genuine affection that burned through her. After a moment, it faltered and Celestia creased her lips into a thin line when she remembered she was still supposed to be punishing her pet.

Clearing her throat much the same way she would when she got off topic during a lesson, Celestia directed her attention down to Twilight - still half kneeling near the bed. “Stand up straight,” Celestia commanded. Twilight obeyed before her mind had a chance to realize what she had done. “Dance for me,” came the next command. Twilight blushed and obeyed, having done something similar on many occasions for her mistress.

Twilight stood tall on her hind legs and wiggled her hips as she brushed a hoof down her body spinning slightly as she did so. Running her hoof down her chest as she faced away she leaned down and presented herself, winking at her mistress as she did. Already Twilight could hear the bed sheets moving as Celestia’s enormous beast of a cock woke from its slumber. Twilight leaned forward more and more until she pushed herself up and stood on her forehooves, smiling at her mistress. Celestia ran a hoof across her shaft, nearly breaking Twilight’s concentration.

However she was bound, and determined to do whatever her mistress demanded. Swallowing hard, she shifted her weight to her right hoof and extended one of her hind hooves. outwards, showing off her flexibility. In a feat that required tremendous concentration, she took her breasts in her magic and pulled gently on her tits. A barely audible gasp came from Celestia, emboldening Twilight as she continued her dance. She charged more power and gripped her own body in her magic, making her spin twice before gracefully landing onto her hooves, whereupon she strutted up to her mistress, already wondering what she would do next to tease her goddess.

The sight of the twitching, engorged mass of her mistress's’ cock stopped all thought within Twilight, it was so huge! She had worked on her dance for awhile but it was hardly over. A wolfish grin overtook her mistress's’ face and with the smallest of nods Twilight shivered and obeyed. Hopping quickly onto the bed and trotting past her mistress, she allowed her to observe her entire body before she had one last glance at the sopping wet marehood that glistened under the tiny bit of light.

“You have outdone yourself, my pet,” Celestia moaned and gave Twilight’s flank a firm smack as it passed her by. “Truly enchanting.”

Twilight smiled inwardly and made a note to wear the same outfit more often. Maybe only once and awhile so it would still hold its elure. Rarity would be the best pony to ask about it … she shook her her head slightly and leaned forward on the bed presenting herself to her mistress, both submitting and invitingly.

Celestia just smiled at her pet’s enthusiasm, but did not accept her open invitation. Instead, she lay on her back beside her pet. Twilight caught her eye and a moment of confusion passed in front of her eyes. “Mistress? I thought you enjoyed this position.”

“Oh I do my pet, however,” she said, her horn lit up as her magic took hold of her massive mostly hard cock and levitated it up for all to see. “That position would make me do all the work and while you lied there and enjoyed yourself. We couldn't have that, after all.”

Twilight’s near instant panic was soothed somewhat by Celestia’s calm expression however she still jumped at the opportunity to fix her mistake. She looked down at Celestia, which was not something she was used to doing and then at her levitating cock, held at the perfect height for her. Without thinking, Twilight found herself licking her lips at the mere thought of that giant pillar of alicorn cock. It instantly made her mouth water and a faint twinge of hunger come from her gut.

Looking down again at Celestia, Twilight saw the ghost of a frown crease her lips. Taking the hint she quickly straddled the larger alicorn, doing what she could despite her smaller size. “Are you sure this is alright, mistress? I am not used to being on top.”

Celestia’s gentle smile calmed her nerves somewhat. “Twilight, you are servicing your mistress while I do little more then relax and let you do all the work,” Celestia stated. Seeing that her pet remained unconvinced, Celestia continued. “I tell you what. I was going to save this as a surprise for another time buuut ...” letting the sentence hang as her magic grabbed something from inside a drawer across the room. It floated towards Twilight’s neck.

Twilight jumped a little as she felt something click into place around her collar and tug her forward. Looking down she saw a long silver and gold leash had been attached to, and despite her logical side saying this was silly, she couldn't help but feel even more turned on by this as she was now at her mistress's’ every whim.

A moan slipped from Twilight’s lips before she had the chance to stop it, drawing a grin from Celestia. “I knew you would like it my pet. Now then, your mistress is hard,” she suggested. Twilight’s body moved on its own, Celestia’s statement being a command, every fibre of her being moved to oblige.

Twilight felt the collar turn on her neck until the leash faced backwards, held aloft by Celestia’s magic. As she shifted around trying to place her dripping sex against the massive rod of her mistress, she felt the leash pull suddenly, forcing her backwards. The massive cock made hardly any headway even with Twilight’s copious juices easing things considerably. Both mares moaned audibly as the cock head barely squeezed inside Twilight’s tight cunt.

Twilight shifted her hips and tried to find a perfect position to push back but Celestia interrupted her before she could move. “Hurry up slave, your mistress demands to be pleasured,” ordered Celestia. Her words were harsh, but Twilight could see the smile on her face.

With a fresh wave of arousal from Celestia’s words, Twilight nodded once and without a second thought threw herself against the cock head, barely able to poke its way inside her. For a moment nothing happened and Twilight was left to wonder if sleeping with it inside her had done anything to loosen her up at all. However a second later she felt it starting to slip inside and nearly lost her balance plunging nearly half of the tower of alicorn cock deep inside her. Celestia let out an uncharacteristically loud moan, while Twilight was left cringing from the pain. Within seconds however it dissipated as her alicorn physiology adapted and loosened enough to allow the massive invader enough space.

“Don't stop there, slut,” growled Celestia, as she tugged harder on the leash pulling Twilight away and further against her mistresses’ cock.

A pained moan escaped Twilight’s lips before she bit down gently, stifling it. Forcing herself to bite through the pain, she continued to work at filling her aching pussy with more of Celestia’s amazing cock. The insistent tugging on her collar wasn't enough to choke her but it was a constant reminder of her mistress's’ will - and something about that turned Twilight on more than she cared to admit. Her hooves gripped the satin sheets as much as they could as she pushed herself backward against the massive cock coming to a rest against the huge medial ring.

Gripping the sheets tighter, Twilight took a few deep breathes before throwing herself backwards. This time the cock slipped inside her with ease, the copious amount of mare cum that had dripped down the length of Celestia’s cock lubing it just enough to allow access. Once over that proverbial hurdle, Twilight stopped to catch her breath. However a now familiar tug at her neck made her open her eyes, just in time to catch Celestia’s deep frown.

“I didn't say you could stop, slave.”

“But mistress, I need time to-” Twilight closed her mouth, her begging doing little to stifle the older alicorn’s disappointment.

Grimacing to herself, Twilight redoubled her effort, heedless to the slight pain of being stuffed so full. This time she lit her horn and exerted and pushed herself back using her telekinesis. Inch after inch slid inside Twilight’s now quite full cunt until she felt the now familiar feeling of Celestia’s cock head resting against her cervix. By now her cunt burned and even her earlier excitement wasn't enough to lube all of Celestia’s massive cock.

The pain had become immense after the last few inches, and even the pleasurable feeling of fullness couldn't outweigh the sheer amount of stretching happening inside her. Silently she wished they had stayed locked together longer as maybe it would have had a more permanent effect on her too tight pussy.

However, through the haze of pain and despite the fact that she could literally feel the waves of annoyance from Celestia, a subtle warmth came from beneath her. It was small at first, radiating up her hooves in slow waves but it was there. It was a feeling she could not describe, the closest she imagined was the warmth she felt when her friends surprised her with a party, or that time that Spike had organized the library and brought her breakfast in bed when she was sick. It felt like … love.

Strange feelings aside Celestia’s insistence on stuffing her absolutely full domineered anymore thoughts. Twilight refused to meet Celestia’s eyes, fearing the disappointment they might hold. Biting her lip harder she pushed forward slightly before slamming her hips backward until her butt rested firmly against Celestia’s crotch. A content sigh escaped her mistress’ lips after her cock slipped through Twilight’s cervix and poked against the other side. Twilight’s face twisted in pain for several agonizing seconds until the waves of love radiating from beneath her washed away any discomfort, leaving behind a near endless ocean of pleasure she was quickly lost within.

Twilight’s tight lace outfit stretched over the obscene bulge in her stomach exaggerating the heart designs until they were unrecognizable. Twilight’s moaning became unintelligible when she felt Celestia’s cock twitch inside her deepest reaches. A second later she felt a tug on her leash, forcing her eyes open only to meet Celestia’s insistent gaze.

“Go on my pet, hurry up or i will do it for you,” she ordered. Twilight considered slowing down and letting Celestia make good on her threat but decided going against a direct order wasn't worth it, no matter how curious she was.

Twilight heaved her hips forward until she felt the medial ring nearly slip out of her before she threw herself back. Every thrust back and forth made her stomach bulge as Celestia’s cock slipped out of her womb only to slam back inside once more. Her mistress seemed to enjoy it but Twilight wasn't used to such a physically demanding position and she quickly felt her relatively low endurance give in. For it was arduous work and within minutes her knees burned under the strain. To top it all off the position hardly allowed the small alicorn to do anything other then push forward and back leaving her unable to lavish her mistress with the kiss she seemed to be longing for.

“Mistress my knees hurt, I don't think i can keep doing this i'm sorry,” Twilight cried as she stopped with Celestia’s cock firmly embedded inside her, panting and out of breath while her knees visibly shook.

Celestia’s frown deepened as she looked her slave up and down. However when their eyes met once more, Twilight saw the usual caring she’d beheld everyday since she first met Celestia.

“Very well, my pet, consider your punishment postponed,” Celestia commanded. Twilight almost breathed a sigh of relief. “But i rather like this position,so allow me.”

Twilight cocked an eyebrow but instantly understand when she felt Celestia’s powerful aura overtake her entire body. The feeling was orgasmic as her every movement was completely and utterly restricted allowing only her breathing to remain unrestricted and her muzzle loose enough to allow her to speak.

Twilight’s analysis of Celestia’s spell was interrupted when she felt her body lurch forward, being dragged roughly along the massive cock still resting inside her. Along the massive cock she slowly moved, more and more slipping out of her while she whimpered pathetically. Only the medial ring slowed her movement for a moment as it audibly popped out of her. A second later she felt as though she had been turned inside out as only the massive head of her mistress's’ cock still resided inside her. Her pathetic whimpers became more desperate as Celestia simply held her there aloft in her magic.

“What do you want, little pet?”

Twilight whimpered one last time before reluctantly speaking, a blush already rushing across her face as she knew what was coming. “I need your cock, mistress, please.” She felt her body shift back a little and before relief could flood over her she stopped only a few inches down. “Please, mistress oh please, i need you. I feel so empty without you.”

Celestia merely smirked and turned Twilight’s head so she could meet her gaze. “Beg for it, my pet, beg for my cock and I might just let you have it.”

The way Celestia had made that last offer almost made Twilight think that she genuinely wouldn't give Twilight what she craved. The mere thought of losing the chance to pleasure her mistress galvanized her thoughts.

“Please, mistress, I need it, I crave it, it's the only thing I think of, and unless it's inside me every waking moment I ache from the emptiness inside me,” Twilight’s pathetic sounding voice was doubled by her wobbling lip. “I will do anything mistress, absolutely anything to have your cock inside me once more and to feel your warm cum fill my womb. Fuck your little cock sock, please mistress.”

Celestia’s face remained a stoic mask the entire time Twilight spoke, but the second she stopped to take a breath and think about what more to say, she saw her mistress’ face light up with a huge smile. Before she had a time to congratulate herself on getting better at dirty talk, which was Celestia’s favorite, she felt herself thrown backwards as Celestia’s cock quickly filled the entirety of her cunt.

Twilight could do nothing but mumble half formed words that quickly devolved into unintelligible moans as Celestia used her. Celestia grunted from the effort and held Twilight tightly in her aura using her like an oversized sex toy. Slamming her up and down, her long cock at a near break neck pace. Anything either of them would have said was lost under the unintelligible grunting and moaning combined with the wet slapping sound when Twilight’s hips met Celestia’s.

Twilight came several times. There was no warning and nothing she could do to stop it - being held so completely by her mistress destroyed her very ability to speak. All the while she felt the same loving feeling permeate her very being. When she was finally able to become acustomed to the massive waves of pleasure assaulting her mind, she noticed her cunt felt utterly destroyed.

Being thrown up and down on Celestia’s massive cock at such a fast pace made her cock slam in and out of her cervix so quickly that by now it held no resistance. Celestia’s cock slammed through the barrier before it had a chance to tighten again. Twilight twisted her head as much as Celestia would allow and looked down at her stomach. What she saw nearly made her cum again, a mere thirty seconds after the last time. For her belly bulged obscenely with every thrust. Celestia’s enormous cock left a distinct outline every time she felt her hips press against Celestia’s crotch.

Celestia had centuries of practice in magic but this pushed her to the very edge of that training and experience. At first the pleasure worked against her concentration, making Twilight almost slip out of her grasp more than a few times. However after a few minutes and a couple hundred thrusts she could feel that same lust driven pleasure enhancing her concentration. All at once the need to pay so much attention to her spellwork seemingly vanished as that same intense desire to use her slave like the cum dump she was poured power into the spell instead of removing it. Free to enjoy the sight of her slave Celestia smiled at her hoof work. Twilight was reduced to a gibbering wreck cumming every minute like clockwork as the changeling spell and her own less than tender ministrations drowned her in pleasure. Even though Twilight’s stomach was still full of potent alicorn cum that had not been digested, she could still see Celestia’s cock poke and stretch the skin of her little slave.

She drew an enormous amount of pleasure, so much so that the last of her resistance finally caved and she threw Twilight down onto the end of her cock and locked her firmly there. The audible churning noise drew a worried thought from Celestia. Could it be that Twilight had teased her too much? There is no way the little alicorn was ready for a full load from Celestia’s powerful balls. However the thought was gone as quickly as it came It didn't matter if she was ready as it was coming far faster than even she could stop.

Twilight cracked her eyes open at the last second as she felt the enormous cock inside her begin to twitch and pulse. “Mistress?” Her eyes went wide and whatever she was about to say was lost as the first massive load bubbled up Celestia’s thick cock. It was so massive that despite Twilight’s already stretched and abused cunt, she could still feel the lump the massive load made as it traveled up the thick cock.

A millisecond later she felt it splash into her womb. The thick flared cock head of her mistress keeping it locked inside. Her eyes rolled back into her head while her tongue lolled out of her mouth. “Cumming, mistress,” groaned Twlight, an orgasm barely held back, a bit lip crushed her thoughts as it rolled over her body.

Twilight shook as her body was wracked by more pleasure than she had ever felt in her entire life. However one thought, one idea shone through the haze. “I love you, Celestia,” she cried, over and over she repeated it from a mumble to a yell as her own orgasm peaked.

Celestia herself was a moaning wreck who could do little more than hold Twilight down as she filled the smaller alicorn’s womb with her seemingly endless supply of cum. Barely above a whisper she spoke. “I love you too, Twilight my pet.”

Twilight heard the words she had so desperately wanted to hear for over a decade and her orgasm she thought had already peaked hit a new high that she didn't think was possible. She wanted to thank her or perhaps continue to simply mumble how much she loved her mistress over and over, but a fresh blast of cum splashing into her womb changed her focus. She felt her stomach distend, sloshing around as her slowly dying orgasm shook her body. She hadn't had the presence of mind to count Celestia’s seemingly endless loads but if she had she would have been shocked to feel load number eighty splash into her womb.

For nearly a minute both mares merely panted, exhaustion creeping up as their orgasms finally died off. Celestia’s orgasm tapered off much slower than the mare on her cock, who could do nothing but gawk as her stomach continued to grow every passing second. Quickly surpassing ‘pregnant with twins’, it only seemed to slow at ‘nine months pregnant with quadruplets’, before finally stopping after she could no longer even see her own legs.

Twilight and Celestia both gawked, unable to do anything but stare as Twilight’s stomach grew painfully large. Celestia shook the astonishment from her face first and gently pulled Twilight from her cock, causing the last few spurts of cum to shoot all over Twilight’s wings and back. Instantly the sheer pressure shot out gallons of cum from within Twilight’s packed womb. Her stomach shrank until it was no longer painful, then seemed to stop. Twilight could feel herself slowly begin to tighten back up, her alicorn physiology already going into overdrive. Inwardly she cursed as that meant she would have to deal with her womb closing and making her deal with her distended belly for the foreseeable future however… Looking down at it she could feel a sense of immense pride coming from inside herself. This is what it would look like if i was pregnant with Celestia’s foals.

The thought sent shivers down her spine and looking down at Celestia who was busy staring at her massive belly Twilight could tell similar thoughts were running through her mind as well.

After both mares had time to gape at the sheer size of Twilight’s belly Celestia unhooked the leash and tossed it aside for now. Left wondering what her mistress was thinking, Twilight cocked her head only for her answer to come a moment later in the form of Celestia gripping Twilight’s collar tightly and dragging her forward into a forceful kiss. Twilight collapsed against Celestia’s chest, unable to stand any longer. If Celestia noticed, she didn't seem to care, and continued to kiss her pet. Only breaking the kiss reluctantly as she felt Twilight begin to tremble as exhaustion took hold of her.

“Did you enjoy yourself, my pet?”

Twilight nodded weakly. “Yes, mistress.”

“Good.” Celestia gently ran a hoof through her pet’s name cooing softly as the smaller alicorn regained her bearings.

There they sat until curiosity finally got the better of Twilight. “What exactly did Chrysalis’ spell do?”

“What do you think?” Celestia’s tone was patient and reserved, the exact same one she used during Twilight’s tests.

The thought of being tested that arouse from Celestia’s tone of voice gave Twilight the energy she needed to formulate her thoughts. “It felt like i could sense emotions. When you kissed me i felt warm and i remembered all the times i felt truly loved.” Twilight tilted her head up enough to look into her mentor’s eyes.

A slight blush dusted the elder princesses’ cheeks. “You are correct my pet, since you lack the organs necessary to eat love when a changeling bestows a boon upon a pony, it makes them keenly aware of the emotions of those around them. And in your case, you got swept up in it,” she explained. A twinge of guilt rolled in Twilight’s stomach, but the gentle smile of her mistress remained.

“Don't worry, I saw that part comin., I forgive you of course,” Celestia booped Twilight’s nose playfully, drawing the studious mare from her inner turmoil. “Well that and it should make you incredibly fertile for a few hours.”

Twilight’s mind came to a crashing halt. Ideas and thoughts smashed into each other and leaked out of her mouth. “Wha wha what?” A sudden energy filled her and she stood up quickly. Her belly sloshing audibly in the silence.

“Are you telling me ...?” Celestia was already nodding as Twilight stuttered and continued. “I'm going to bear your foals?” Celestia nodded still. “Me?”

Celestia rolled her eyes. “Yes, my pet, you will bear my children. No, our children.”

Twilight’s eyes became the size of dinner plates and she could hardly contain the excitement welling within her. In an instant, all the exhaustion and aches and pains fled from her body and were forgotten.

“However, we only have a few more hours left on the spell so…” Celestia was tempted to order Twilight into position, but the fire that burned in her eyes told Celestia she wouldn't have to.

The sheer ferocity in the small alicorn’s eyes nearly made Celestia double take, and before she could get a word in edgewise she felt her still semi hard cock rammed into Twilight’s sopping wet pussy.

A moment later Celestia was hard once more, minutes later she came again, hours later they would lie awake in bed talking about foal names.
