"ENOUGH!" Alexandria roared in outrage and Fey felt her begin to change.
This time it was different from a simple decompression of her size; the dragoness wasn't just decompressing, she was changing, mass being created out of nothing as she grew larger, body morphing.
She grew beyond her limit, fifteen foot, sixteen, her face changing and becoming more feral, more terrifying, muzzle longer, seventeen, nineteen, twenty foot tall, neck lengthening, wings going from petite to huge.
The dragoness's belly was rapidly shrinking, the space in her womb multiplying as she grew, her thighs reaching down either side of the room sized pillow to the floor as it became more fitting for her size. The maids now tiny in comparison were sent running for their lives, or falling across her thighs.
Fey watched in disbelief as she was thrown into shadow and the immense pussy she was buried in grew larger and larger, fat and puffy and huge, her horse legs embracing it, hooves sinking into the soft flesh.
The dragoness groaned and growled as she expanded and a spray of girl cum, far larger than previous washed over Fey in a wave as the Dragoneess's head reached the ceiling fifty feet in the air above, drenching the pillow.
Then, with a yelp, Fey found herself being pulled along as the massive dragoness fell backwards, her back coming down on the endless pillows filling the one hundred and fifty foot long hall with a crash, the entire building shaking.
The dragoness continued to grow, her now huge wings hiding the walls from sight either side as her back legs stretched upward, her feet touching the ceiling then moving along it as her legs lengthened more.
Fey found herself slumped on the dragoness's body-sized pussy, her melon-sized clit right in her face, a pulsing fat pink thing poking from its scaled hood.
Fey peeked over it and looked up the vastness that was Lady Alexandria's true natural form.
She was… very big.
Looking up her belly was like looking over an immense scaled plain which a few scattered maids were wandering around on in confusion. The end of the plain led up to a long neck where a startled Alexandria head looked down upon her.
The dragoness looked over her body, seemingly surprised by what she had done. But then she furrowed her brow, contempt returning.
"To think you forced me into my true form, I- wait, what are you doing?!"
Fey continued humping the giant pussy she was huggin, hands grabbing hold of the giant clit, hips pistoning in and out of the cunt.
"N- need to cum!"
For the first time a look of real concern appeared on Alexandria's face and she lifted one enormous set of claws to remove Fey. But then Fey bit down on the clit in front of her and squeezed her hands together as hard she could, pulling and tugging.
A sharp gasp came from above, the dragoness trembling, her back arching as Fey continued to frantically masturbate her massive clit all while her hips slammed over and over into the person-sized pussy.
The dragoness squealed as Fey buried her face and rubbed it all over the clit, nibbling and licking at the thing her magic had made hypersensitive. Dust fell from the ceiling and the entire building rocked like in an earthquake as the dragoness thrashed.
With a crash one of her feet went through the ceiling, then the other as her legs extended, toes splaying.
"Oh- GAAWWWDDSSSS!"
Fluid exploded around Fey's body, a wash of boiling hot girl cum entirely submerging her body below her shoulders as the dragoness squirted lakes.
Despite this Fey didn't stop humping, only urged on by the intense smell of the dragoness's body going wild, her pheromones causing her balls to swell even larger, hips pounding over and over and over into her pussy, more and more violently, the massive soft pussy rippling with each impact, the dragoness's voice rising to such a pitch that all the windows in the hall shattered and exploded outward, only urging Fey on as she beat up the clit, her hips becoming arrhythmic they thrust so frantically.
And then Fey came.
The dragoness threw her head back in a scream, and her head went through the back wall as her pussy clamped down like a vice, locking onto Fey's length, Fey's four foot wide balls hiking up hard as they released into Fey's length, compressed cum surged down her shaft and then spraying and slurrying into the dragoness's womb where it was free to expand.
Fey howled, screaming into the dragoness's clit as it felt like her balls drained as an ocean.
If she had been looking up she might have seen the vast plain of the dragoness's belly slowly start to rise, immense dragon musculature clenching down, desperately trying to compress it and keep it back, but finding the sheer quantity just too much. The plain rose in a great arcing curve, a massing dome of pale belly each clench of her poweful abdomen only slowing it, pulling it back in slightly, before the next pump of cum sprayed into her and her belly rose feet further, visibly quaking and vibrating under the extreme pressure. The scattered maids cried out in alarm as the ground they stood on became a dome that they began to slide off.
The hall was starting to come apart now, the dragoness's claws clutching at her growing belly as her body thrashed, back arching, wings extending through the walls as her feet kicked apart the back of the hall, a near constant spray of squirt forming a lake below her hips, the maids being washed away.
Her belly grew uncontrollably, pushing apart her claws, everything she did to try stop it, it grew well past nine months pregnant with octuplets, a vast sphere that reached up and up until it touched the ceiling and the walls of the hall were being pushed out to either side, her full throated screaming silencing the entire city of Bine, her body a cathedral to horse cum and mind shattering pleasure.
It seemed like the hall was going to be destroyed entirely, but then with one final roaring surge and a soft squeak from Fey it came to an end, the centaur falling unconscious atop the dragoness's massive clit, mouth parted, lips smeared across its pulsing throbbing surface.
Lady Alexandria let out a long exhausted groan and went limp.
The city of Bine panicked.
