FLUFF AHEAD....kinda

-------------------

(y/n) and vaati were currently in a giant, floating field, practicing magic. While vaati could control wind and lift things, (y/n) could control water and ice. Well not really water, but she could turn it into ice or snow. To say who had the upper hand was a tricky question. I mean, (y/n) can fling sharp, deadly pieces of ice at him, but he could easily use the wind to turn the weapon around.

" VAATI!!! WANNA SEE A NEW SPELL I'VE BEEN - GAH!!!"
The (h/c) dogged her own ice daggers
" WORKING ON!?"
She yelled across to the purple clad mage, knowing he probably couldn't hear her anyway. Vaati locked Gaze's with her for a split second before raising his open hand, a tornado quickly coming up from the ground of the platform. The ice mage gasped and rolled to the left as it came racing towards her. She stood up and glared at vaati shooting small, sharp pieces of ice from the palm of her hand. Vaati jumped but one piece grazed just under his eye, blood slowly running down his cheek. He raised his hand to his face, lightly touching the cut. The girl took this opportunity to use the new spell. She rubbed her hands together and placed them in front of her. Chanting a few words and opening her hands, a small blue orb forming where her wrists met. By the time vaati noticed what she were doing, the orb was about the size of a pumpkin
"oh, crap"
Vaati's eyes were wide and he turned to run but a beam of blue shot towards him. He froze in a cube of pale purple ice which rose into the air. The (h/c) smirked and chanted some more words, a blinding purple light enveloping vaati's cube. After a few seconds the cube shattered and vaati fell to the ground...as a toddler! The mage giggled and ran up to the purple child who was trying to figure out why the world was so big. She grabbed him by the sides and spun him around, cuddling him to her chest afterwards. Vaati put his hands on her shoulders and tried to push her away. He froze when he saw the tiny adorable hands that belonged to him
" (y/n)! What have you done?!"
The mage squeaked out, covering his mouth afterwards. He blushed a deep red, hiding his face between the girls boobs. (y/n) gasped lightly but didn't pull him away, instead,she claimed victory in her head and teleported to the living room in vaati's castle. She pryed the toddle away and placed him on the couch. He quickly used his powers to get a pillow, covering his embarrassed face. The now elder mage giggled and snapped her fingers, a bowl appearing in front of her.
"hey vaati, can you bring the bubble gum flavored syrup over here?"
Vaati groaned a squeaky groan but waved his hand, bringing the pink can over to her from the table. (y/n) thanked him and grabbed the floating flavoring. she wriggled her fingers over the bowl, shredded ice slowly filling it to the top. Once it was full, the (h/c) poured the bubble gum flavor over the top, staining the ice pink. She sprinkled edible purple sparkles over the frozen treat and stuck a spoon in it, handing it to vaati. She nudged the purple haired villain, who peeked over from his pillow. He smiled and Quickly grabbed the large purple bowl. Bubble gum was his favorite flavor, and purple was his favorite color, obviously. He grabbed a large spoonful and shoved it into his mouth, shivering at the coldness and purring in delight.
After finishing the dessert vaati yawned and lay down on the blue clad mages lap. She chuckled and patted his hair, falling asleep after a few minutes.

" y/n ~"
"uugghh "
"wake up y/n~"
y/n sleepily opened her eyes,yawning in the process. You jumped back and chucked nervously at the adult vaati infront of her. She didn't think the spell would ware off so fast.
" that wasn't a very nice trick y/n ~"
She smiled and scratched the back of her neck
" oops ~?"
Vaati growled and pinned her hands above her head, pushing her into the couch. The (h/c) blushed and yelped.
" no, no oops y/n"
Vaati leaned down , she could feel his hot breath on her lips. Vaati smirked and closed the gap, kissing the girl lustfully. He swiped his tongue across her bottom lip. When she didn't open her mouth, vaati growled and gave her but a hard squeeze. Y/n gasped, vaati quickly plunged his tongue into her mouth, exploring every crevice. After about 20 seconds vaati broke the kiss, a string of saliva connecting the two, panting slightly. Y/ns face was a deep crimson,eyes blown wide
" time for your punishment ~"
