The royal throne room was abuzz with negotiating ponies, two earth pony families fought over who had rights to the local river. It was far too shallow for both of them develop thus their bickering had eventually caught the attention of Princess Celestia. She brought both families to Canterlot in order to personally deal with the matter. Her regal figure sat upon the golden throne, her violet eyes watched the lips of the speaker. Occasionally she would shift in her seat to make a motion, allowing the other pony to speak their word. This certainly wasn’t the first time the princess had dealt with an issue as such nor would it be the last, at least an entire city wasn’t on the line.
There was a loud knock at the giant doors to the throne room. It echoed for a moment which made Celestia look up from her current task. The alicorn raised a hand to silence the speaker then her lips parted, sucking in air for her words.
“Enter,” She spoke with authority yet it rung with softness throughout the chamber. The door opened and a single guard stepped through the doors. His golden armor glistened in the chamber’s natural sun light.
“Princess Celestia, we found her,” The guard spoke, he bowed to one knee in honor the leader of the land. Celestia raised an eyebrow, a smirk formed across one cheek.
“Is that so…? Bring her here please,” The princess spoke, the guard nodded in response. Her gaze settled upon the earth ponies.
“I’m quite sorry but something has come up. My guards will lead you to your resting quarters. I will think upon both your statements and come to a conclusion tomorrow. Until then please rest and enjoy Canterlot,” Celestia smiled to her guests. The statement was followed by many ‘thank you’s and bowing. The princess motioned to her two guards at the entrance to escort the ponies away.

Only a handful of minutes later an unimpressive white unicorn was brought into the chamber flanked by two guards. She struggled, presumably the mare had run out of profanities by now. Despite her struggle the guards retained a firm grip on their captive’s arms.
“Thank you guards. You are dismissed,” Celestia spoke as she rose from her throne.
“Bu-” Both guards dropped the prisoner to the floor with a thud.
“I can handle what she throws at me,” Celestia cut the protesting guards off.
“Of course,” With a single bow they both left in perfect practiced unison. The massive door closed, yet not a sound was made. Celestia locked the doors with her magic then focused her attention on the prisoner. The white mare glare at the princess but the princess spoke before she could.
“It’s been some time hasn’t it… Chrysalis,” Celestia emphasized the final word which shocked the unicorn. “Surprised? I cannot blame you Changeling Queen but my sister’s dream walking betrayed you the moment you slept within my realm. No need to try anything brash, you’re no longer fueled by some of the strongest love in the land - you are hardly my equal now,” Celestia’s voice was harsh, true and powerful. Each word sent shivers down the Changeling Queen’s spine. She was alone with one of the most powerful beings in the realm. Yet if she could replace Celestia Equestria would be hers to rule! Despite these daring thoughts she found herself incapable of acting upon them. Step by step Celestia descended from her throne until at last she stood on the carpeted marble floor. The next words shocked Chrysalis however.
“There’s no need to be afraid… take your true form,” Celestia tenderly said, her expression was calm and affectionate towards the bug-like creature. With a nervous gulp the charade of a white unicorn was swallowed in green flickering flames. The carpet she stood on did not burn nor was the fire hot. As soon as it started the green inferno faded to the royal air. Now golden sunlight fell upon the onyx form of the Changeling queen. She looked up at Celestia, they stood not three feet from each other and it was clear that the eldest alicorn dwarfed Chrysalis.

Queen Chrysalis’ eyes took in every aspect of the regal ruler. Her mane flowed, swirling with color in an absent wind her tail did similar but slower. Princess Celestia rolled her shoulders as her noble robes came loose. The golden garment slipped down off her body to the floor exposing a much different Celestia. Indeed what stood before Chrysalis was very revealing, the reserved princess of the sun now wore garbs that draped over her huge bosom. Above her right breast was a purple brooch that held her clothing together. Chrysalis looked across the princess’ body and blushed as she noticed how ill fitting Celestia’s attire was. Clear as day Celestia’s areola was posed and her clothing peaked with a perky nipple.
“I didn’t expect such a reaction from a ruler like yourself,” Celestia giggled a little, she raised one hand to hide her smile. Chrysalis finally looked up to Celestia’s face, her jaw was pushed closed by the princess’ index finger.
“Before you ask ‘why’ I simply wanted to get more comfortable. I suspect we’ll be talking for some time…” Celestia began, her tone was relaxed and surprisingly playful. Chrysalis nodded slowly, her mind tried to predict what was happening. Was this a trap? Was Princess Celestia simply feinting this kindness to strike the Changeling Queen down? Her mind raced for an answer but nothing came.
“I suggest you do the same before something unfortunate happens,” Celestia recommended to the Changeling. Almost mindlessly she obey and stripped off her clothing, kicking it to the side. It was cheap and allowed her disguised form to blend in with the people of Canterlot. Princess Celestia nodded slowly, her eyes scanned Chrysalis just as the Queen had done earlier to her own royal body.
“Mmm… I see, I see…” Celestia muttered, her prying eyes confirmed her suspicions. She stepped softly on the purple carpet making no noise, she returned to original position in front of Chrysalis. “Yes… I believe I know the right punishment for you now,”
“P-punishment!?” Chrysalis stumbled back, it wasn’t a surprise to her but the words hung in the air like a rotten apple’s scent. Celestia’s pleasing demeanor returned which lifted the air only slightly.
“Indeed but do not fear. You lack the endowment of a Queen, it’s not surprising your drones are going hungry. As such your mobility will be more limited and your invasion forgiven Chrysalis,” Princess Celestia spoke, her horn began to shine with alicorn magic. It was bright like the sun and Chrysalis felt a tickle around her D cup breasts.
The tickle rapidly became a heated pulse throughout her body with the epicentre being her breasts. Queen Chrysalis looked down in surprise as her D cups had rapidly swelled to a double H cup. A bright yellow light surrounded her expanding boobs, a perfect match to the color of Celestia’s horn.
“There we go… doesn’t that feel better?” Celestia asked softly. Chrysalis stumbled slightly, her balance was thrown off but thanks to years of disguises she was barely able to stay standing. Her gravity shifted as her boobs ballooned bigger and bigger! The Changeling Queen couldn’t reply to the alicorn’s quip, her full attention was on the pleasure of her growing mammaries. Princess Celestia’s magic was potent, she require little to no focus on the magic she was currently using. Bigger and bigger Chrysalis grew, her knees braced against each other for support as her bosom was now as big as Celestia’s impressive bust.
“S-stop…” Chrysalis finally moaned out through her pleasured pants. She felt hot, waves of pleasure pulsed throughout her body and it was near impossible to focus on anything but her swelling breasts. Princess Celestia smirked, she leaned over slightly with her hands on her hips then her purple eyes looked down upon the Queen.
“Not quite… I think you deserve more for your invasion,” Celestia answered. Queen Chrysalis groaned and looked down in shock yet awe of her huge beautiful onyx breasts. They were bigger than the alicorn’s now, certainly more than enough to feed her hive. They felt heavy and full of life giving nutrients.
“I know it’s not quite love that Changelings desire but it should be enough to feed your hive,” Celestia said as her horn’s glow faded away, in conjunction the magic around Chrysalis’ breasts faded too. At last the Changeling could catch her breath. Despite the break in magic the pleasure still tingled across her body and it took all her restraint not to be anymore indecent in front of the princess of the sun. Her fingers trembled, itching to relieve her moist and begging pussy. Celestia’s playful smirk returned, as if a mind reader she motioned to a separate private room.
“Follow me Chrysalis… we have much to discuss…”
