Cadance's Baby Quest

“You seem quite eager sister.”

Celestia shook her head, taken out of her sweet memories by Luna’s voice. She realized she was wearing a silly little grin, her wings fidgeting as they walked side by side. Their steps echoed around the Crystal Empire’s castle, and hers were hurried and nervous, while her sister walked with the grave and decorum expected of her station. She tried to school her features, but she couldn’t fool her sister that easily.

“Twould almost seem like it is thou who just had an offspring, not Princess Mi Amore and Captain Armor.” Teased Luna, snorting at her own joke. “Thou look positively delighted.”

“Well, of course I’m excited to see Cadance’s foal.” Celestia smiled pleasantly, hiding the thrill of fear she felt at Luna’s words. “I have known Cadance since she was little, practically raised her.” Celestia put on her best motherly mask. “She is like family, and so will be Flurry Heart.” She beamed, remembering how happy she had been when she had received the news of Cadance’s safe delivery. “I’ll be a good mother to her.” She blinked, realizing what she had just said. “I meant grandmother!” She corrected hastily. Too hastily.

Luna’s ears flicked, then she slowly turned her head, her smile melting into a neutral expression as she stared at her sister. Celestia kept her serene expression, tilting her head as if confused by Luna’s glare, but internally she was screaming like a little filly caught with her hoof in a cookie jar. Eleven months, eleven months of hiding their scandalous affair, feigning surprise at the news of Cadance’s pregnancy, congratulating Shining Armor without looking down in shame, hugging Cadance and putting an ear to her belly while trying to hide her raging erection, replacing the carpet in her parlor in secret… and she may have just spilled the beans at the worst of times!

“Sister…” Luna began, her left eye twitching ominously. “Pray tell, surely thou did not…”

“Oh look at this, we’re here!” Celestia interrupted loudly, trotting to the nursery door. “Come quick Luna!”

Luna grumbled under her breath, shaking her head. Celestia hid her relief when she saw Luna apparently give up on her line of thoughts, probably thinking she was imagining things, and she knocked on the door happily. Inside were Shining Armor and Cadance, both looking quite tired, but wearing wide smiles. Between them stood a cradle, and Celestia’s heart throbbed in happiness when she saw the tip of a little pink muzzle. She felt Luna’s gaze on her back, so she schooled herself as she approached the couple and their newborn.

They exchanged the usual congratulations to the couple, Celestia having to rein herself-in least she started to prance in place, so impatient she was to meet Cadance’s foal. Their foal. As much as she had agreed with Cadance to never contest Shining Armor’s legitimacy over their child, she just couldn’t wait to spoil the little filly rotten. She always monitored and made sure the foals she helped father were well cared-for from a distance, but this was a special case. Flurry Heart would be family.

“So, I guess you want to see her now?” Shining Armor smiled proudly, despite his exhausted look. “We have to warn you, she has a little surprise in store for you!”

“Yes.” Cadance bit her lips, exchanging a quick glance with Celestia. She looked away just as quickly, but still Luna’s brow furrowed, looking between them suspiciously. “A… surprise. We could have never seen this coming, nope, no way.” Celestia blinked. Was it just her, or did Cadance sound sarcastic?

Celestia pushed her worries aside and leaned forward as Cadance gently took the little filly from the crib and held her in one hoof. Actually, now that she looked closer, she looked quite big for a newborn… Oh, a horn! How lovely! A little unicorn filly, she could become Celestia’s new apprentice! The thought made her heart sore, and she cooed softly as the little filly started to wake. Flurry Heart looked at her with an infant’s wonder, a smile appeared on her little muzzle, and…

“Aguh!”

Flurry Heart’s wings suddenly sprang open, flapping at her sides as she gurgled happily. Time seemed to freeze for Celestia, her eyes going wide and mouth falling open. She felt as if the ground had opened beneath her, and she was falling into the depths of Tartarus.

“An alicorn?” Luna said at her side, eyebrows raised in surprise. “But how… There have been no records of naturally born alicorns in Equestria, this is impossi…”

She cut herself of, and rounded up on her sister who pointedly looked away. Celestia could almost feel Luna’s accusing glare drill a hole in the side of her head. Cadance gulped audibly, smart enough to realize Luna had seen through them, and she flinched when the dark alicorn glared her way. The three alicorns were locked in a silent conversation for a few instants, Luna yelling at her two fellow princesses with stares and eye twitches, while Celestia and Cadance tried to explain and ask for her discretion with winces and awkward shuffles. After a while Celestia, Cadance and Luna looked towards Shining Armor with fear, guilt, and pity respectively.

“So, what do you think?” The stallion’s gaze flicked between them, the smile on his muzzle never wavering, completely unaware of the silent battle that had just occurred before his eyes. “Isn’t she the cutest little filly you’ve ever seen?” He gushed , leaning over to tickle Flurry Heart’s belly. “Who’s the cutest little filly ever? You are! Yes you are! Say daddy! DA-DY! Oh look honey, she puked on my hoof, get the camera!”

Luna sighed deeply, glanced at her sister and Cadance, and finally gave a reticent nod. She wouldn’t be the one to destroy this stallion’s happiness. Both alicorns breathed in relief, Shining Armor too busy praising his daughter to realize anything was amiss. He excused himself so he could go wash his hoof, and left the three… Or four, alicorns together.

“So.” Luna growled. Both Celestia and Cadance flinched, the two of them shuffling until they were side by side, comforting each other by their proximity. “Explain.”

“She made me do it.” Celestia instantly said, pointing towards Cadance childishly.

“Hey!” Cadance cried out, affronted. She elbowed Celestia in the ribs, much to Flurry Heart's enjoyment, but any more shenanigans were halted when Luna cleared her throat. “… Okay fine, I totally made her do it.” Celestia nodded eagerly. “Though I had nothing to do with what happened the morning after, that was totally her. I woke up and she had already started.”

“It was morning wood!” Celestia defended angrily.

Cadance opened her mouth to retort, but Luna snapped at them. “ENOUGH!” They both closed their mouths with soft *clicks*, looking sheepishly to the ground. “Sister, while it isn’t our place to judge what thou and thy concubine do…”

“Concubine?” Cadance squeaked, cheeks flushing.

“It’s not what you think!” Celestia rushed to say. “We’ve only done it the once.” She said, unable to hide her bitterness at that fact.

“Yeah, we won’t do it again!” Cadance promised, ignoring Celestia’s grumble. “I just needed help to have a foal!”

Luna quirked an eyebrow, clearly not convinced. She opened her mouth, but before she could speak Shining Armor waltzed into the room, a spring in his step.

“It feels so good to be a dad!” Shining gushed, giggling like a school filly. He turned to Cadance, wearing an exuberant grin. “I can’t wait to have another foal with you honey!”

Cadance’s eyes widened in fear, Celestia perked up with a hopeful expression, and Luna facehoofed.

“Oh... Another one?” Cadance smile was strained. “Hmmm… How many do you…”

“At least a dozen!” Shining Armor laughed, a manic glint in his eyes. It might have been the lack of sleep talking, but he did seem honest enough. “Do you think they will all be alicorns?”

Before Cadance could respond and try to curb her husband’s enthusiasm, Luna interjected. “Yes, I believe they will be.” Shining did a little jig of happiness, missing the confused stare Celestia and Cadance were leveling at Luna. Celestia felt a chill, surely Luna wasn’t planning on… “Don’t worry Cadance.” Luna turned to the pink alicorn, a toothy smile appearing on her muzzle. “We will be sure to help you.” She turned to Celestia, the older alicorn puffing up like an angry toad. “Won’t we sister?”

Cadance’s gaze went between the two alicorns, confused at Celestia’s anger, until she heard the distinct sound of flesh slapping against somepony’s coat. The sound had become something of a regular occurrence whenever she and Celestia were together, much to her exasperation. Since that night Celestia couldn’t help but lust for her, popping invisible boners at the worst of times, but Cadance had been clear: sex was off limits, she belonged to Shining Armor. Celestia’s puppy dog eyes often got the better of her though, and Cadance would end up helping the alicorn… relieve herself; but she always refused to let Celestia actually fuck her.

She turned to Celestia, glaring at the princess for getting a hard-on with her husband present, in front of their foal no less, but the sound repeated itself, and it was not coming from Celestia.

It was coming from Luna.

“After all.” Luna devoured Cadance's frozen form with a predatory gaze, eyes lingering on her rear, her fangs glinting in warning. “Sisters should always share.”
