Gwyn waited for a few moments as the music began to play. As the duke and Estrel took to the center of the dance floor, many more nobles filled in around the pair. Most of the other couples gave the enormous Estrel plenty of room, but Gwyn could see something else happening. The most eligible nobles were slowing edging closer during the dance. Clearly getting ready to offer themselves as a dance partner to the new massive beauty twirling around with Duke Montagu. Which meant not only had Estrel captured the attention of Duke Montague, but she was now drawing the attention of every suitable noble that laid eyes on her.
Such revelation brought new life to jealous fire burning inside Lady Gwynevere. She could feel her magic aching to be used, begging to be released in fire and fury. That energy thrummed through her veins responding to her utter contempt for the massive and gorgeous beauty that was Estrel and moment spent looking at the woman only intensified the feeling.
With all eyes on Estrel and Montague, barely anyone even noticed Gwyn as she turned and calmly, but quickly, stalked away from the dance floor. Leaving red hot imprints of her feet in the tiled floor as she went. Her magic, refusing to be quelled, using the only outlet it could find to escape thereby charging her hands and feet and almost her whole body with heat.
Gwyn finally made her way around to the garden again. Ducking Her way through the door she found a tree nearby to use for cover. Why she was bothering she wasn't sure, everyone's attention was currently on the half giant runt known as Estrel. As Gwyn turned around the tree she found the serving staff again, apparently they were keeping the gardens well tended on this event. She couldn't fault that, Montagu's estate was lavish, certainly every part needed immense manpower to stay pristine.
She saw the maid she had seen earlier and Gwyn smiled.
"You there, more silk." She commanded a small smile touching her lips.
"More silk? My lady you, you can't be serious." The maid replied
"Oh?" Gwyn asked leading to a chance to feed her ego
"My Lady Gwynevere, you're already so...big, is it, um do you really, that is." The maid started fumbling for words when she realized who she was questioning. But Gwynevere was expecting this.
"Oh really, you think this is big?" Gwyn said as she stretched her arms above her head and arched her back, pushing her chest outward. The servants gathered stared, shock and arousal clear on their faces as Gwynever's breasts pressed against her dress tight enough to be clearly defined. Every curve and every inch of her massive bosom was outlined by the silk containing it.
As she posed a wicked smile played across her lips. Using her new muscles she held her body tense as she bent at the waist. The 8 foot tall Gwyn lowered her massive chest down to eye level for the servants.
"Well?" She said in almost pouting tone
Silence, then a small cough followed.
"Um, of course not my lady. One such of your….stature, deserves to stand heads above the competition. I uh, think I saw a pair of curtains in the parlor that match this silks color." The servant finished as he grabbed the maid that had questioned Gwynevere and dragged her with him.
Gwyn smiled. Then, uncaring of the rest of the staff staring, she began to work her magic again. She was worried though, she had put a lot of power into her first spell. She wasn't certain that she had enough mana left for another such spell. But really she only needed to be a little bigger, just 2 feet, enough to look down on Estrel. But as she began to focus on her body, on adding more power to the spell already in place Gwyn's eyes flew open.
The serving staff took a step back at the sight they beheld. Lady Gwynever’s eyes were filled with power, such so they were simply pupilless pools of glowing green light. The men and women gathered took another step back when they heard Gwynevere begin to laugh. A laugh they were, well not used to hearing but accustomed to the idea of. After everyone knew mages were prone to madness.
Gwyn laughed, she couldn't help it. It was just too good to be true. Instead of finding her mana reserves depleted, whatever she had done to her body to create this new form had bolstered her body's ability to create mana. It felt like she had barely used any magic at all today.
"AhahaHaAhahaaha! Yes! Oh I am going to love being even bigger." Gwyn laughed as she flooded her body with power, focusing on increasing the enchantments she already had in place. She felt it, the delicious heat welling up in her core again. Then radiating down between her thighs.
"Mmmmore, I need more." She moaned as her whole body began to grow.
Her dress began to pull tighter.
The staff watched in amazement as the already enormous form of Lady Gwynevere began to grow, soon 8 feet gave way 9 feet and Gwyn moaned again. 9 feet became 9'6", then in one finale spurt her body erupted to a staggering 10 feet tall. But she wasn't finished yet, next she felt the heat welling up in her arms, legs, and core. Her muscles tightened, then bulged, then relaxed. They had grown again, still lean, but clearly defined now. But still not a match for Estrel.
Her dress now showed every curve of her massive form.
"Doesn't matter." Gwyn breathed out as she focused "I'll beat her where it really counts. MmmMhhh!" Gwyn released another moan as her ass expanded. Its new size pulling her dress tighter around each cheek and even lifting it up enough to expose her well toned calves.
"Yes, by the king, why does that feel so damn good! Just...need..a little more…ahhh." Gwyn spoke as she focused on her breasts, the already large C-cups began filling with power, and suddenly in a rush that left Gwyn sputtering and falling to her knees her already large chest bulged outward. New massive jiggly D-cups replacing her previous assets.
The dress didn't make it.
There was the sudden sound of silk, the nigh unbreakable fabric, tearing along the lines of Gwynevere's massive new form. Her breasts and ass left completely exposed to everyone around. Fortunately the other two servants had returned with the silk curtains from the parlor. Gwyn quickly reformed her dress to her new, much larger and more beautiful body. But she could again feel the exhaustion from using touch magic at once.
"Note to self, Breasts horde magic like a dragon hoards gold." She said between heaving breaths. As she rose back up to her full height she noted the people around her barely came up to her navel. She laughed again and this time her bosom jiggled with every chuckle. The heads of the male serving staff tracking the movement up and down, while the two females began to self consciously adjust their own garments.
"Alas, my little admires time for me to return to my rightful place as the bell of the ball." Gwyn said as she strode forward, her new dress still clinging tight to her form, showing off her new abs, every jiggle of her pale chest, and the supple rise and fall of her cheeks as she strode away. half crouching as she passed through the now even smaller garden doors.
