“…You’ll never get away with this, Chrysalis!” Twilight snarled towards the Changeling Queen. She was exhausted, but still insisted on trying to escape her unfortunate situation.  
“Oh, but don’t you see, Twily? I already have%” Chrysalis replied, almost salaciously. Ever since being impregnated, she had had an almost insatiable lust for, well, anything really.
 
Twilight, along with her friends, were all tied upside-down to the roof of one of the many chambers within the Changeling Hive, prisoners to their rather swollen captor. Twilight was the only one conscious however; the others were all under Chrysalis’ control, and were put into an induced rest.  
“You see, Twilight, all I had to do was store all the love I could. Who knew that being in an early pregnancy would make me oh so powerful?” Chrysalis went on to monologue, “After growing for a short time, I found it rather easy to deal with that problematic friend of yours, Starlight.” She emphasised the last word with all the venom she could muster.  
“After she was dealt with, all I had to do was go into hiding for a few days. Do you know how many maiesiophiles there are in Ponyville? You’d be surprised. It was easy enough to just claim that I was some poor, pregnant mare down on her luck. Stallions practically rushed to my aid! As did their, ahem, love for my figure.”  
She went on, “There was just so much love in the air, my dear. If only you had the eyes to see it, like I do. You could have cut it with a knife. I personally almost had too much; The form you see before you was starting to tear through my disguise. And I know full well just how adverse you ponies are to eggs. Why I think that they’re just the cutest. It’s a shame that you don’t seem to see them that way.”  
“What… are you hoping to… achie-?” Twilight panted, still trying every so often to work one of her hooves out from the goop holding her in place. Being upside-down for this long was starting to make the princess a tad drowsy.  
“Ah-ah-ah! You do not interrupt the Queen whilst she is monologuing!” Chrysalis barked. “Now, what was I saying? Ah, yes. You know, being so gravid is all fine and dandy for collecting love, especially when harvesting it only makes me grow bigger, causing some of the ponies here to give me even more love than before, but do you know how hard it can be to move around like this? I mean, look at me, Twilight. My belly is the size of a boulder, and my boobs are each half that! Not that I’m necessarily complaining, however. I certainly don’t mind the size%”  
“Now, to answer your pathetic little question, why, total domination of Equestria, of course! I wouldn’t have anything else. I will become the most pregnant changeling in known pony history, and shall bring about the largest changeling army known at all!” Chrysalis squealed with feverish delight. “Why, with the events of the past few days, I’d say that this day has been just perfect!”
 
And with that final thought, something about Twilight changed. She stopped struggling, and instead tried to grab the attention of the all-too-caught-up changeling.  
“You know, Chrysalis, I’ve been hiding it as best I could all this time, but I can’t hid it any longer. I just love how big you’ve grown~”  
Chrysalis was almost caught by surprise, “You… You what?”  
“I said, I love how big you’ve grown, Chryssie.” Reiterated Twilight, this time with a pair of bedroom eyes on.  
“I, oh. Aah, I can see it now. You really do love my shapely form, don’t you?” Chrysalis replied, seeing at what her captor was getting at.  
“Yes. I just love, love, LOVE how much I can cause it to grow. Look, I can see your belly expanding now.” Twilight stated, in a stupor.  
“Oh my, this is simply the best love I’ve ever tasted! I can’t stop!” Chrysalis exclaimed, “Look at how fast I’m growing!”  
Chrysalis’ belly had almost doubled in size since she had revealed herself to Twilight a few hours ago, and was only growing faster. Her giant mound of soft breast flesh had doubled in size, too, and had begun to leak.
 
The changeling continues to feast upon Twilight apparent love for her growing, bulbous form, and soon became immobile due to her own sheer size. All whilst Twilight kept on exclaiming her love for Chrysalis, and how she wants to help make that changeling army dream come true. Chrysalis was all too happy to suck it all in, letting herself get lost in one of the largest meals she had had in a long time.  
Her belly was now big enough to take up an entire room, and each breast was slightly larger than her belly beforehand. She reveled in her own gargantuan size, loving every moment of it. She was just so big, and could only get bigger. In the back of her head, a thought of a clam lingered, whispering “Bigger…” but she tried not to think anything of it. She was too busy enjoying her feast, with Twilight along for the ride.

A sharp tone rung throughout the royal chambers of the Changeling Hive. It was time for Chrysalis to wake up and commit to her duties as Queen. As she pushed her way through her morning haze, she turned off her alarm, and tried to look at the foot of her bed. What greeted her was a large wall of near-black chitin. It took Chrysalis a moment to comprehend just what was going on, but then, it clicked.  
“Ah! Not again!” she almost screamed. “That’s the third time this month!”  
Her vision was blocked by her own gigantic belly, as well as two gloriously huge mountains of boobage to either side. During her sleep, she had managed to shape-shift into the form she was in in her wonderful dream that she was so rudely awoken from.  
Her bed creaked under her, straining with the truly massive form that she had taken during the night. Chrysalis was thankful that her bed was built to sustain such weight being put on it, but this time it was not the weight of hundreds of eggs that bore it down, but the weight she had conjured with her innate abilities.  
The shock from seeing herself was enough to wake her up, and she quickly shifted back into a normal, more relatively petite form, so that she could attend the duties she had later that morning. Even though she could have gotten around her chambers just fine in her pseudo-pregnant form, it was far easier to get out of that disguise than it was to sustain it throughout the day, regardless of how much she ‘secretly’ loved being in it.
 
And that is why the royal chambers are so large. Not as a sign of wealth, but simply so that they can house one of the largest changelings in history.
