The life of Timmy Turner was one of perpetual fear and misery, with a single bright spot in the form of his fairy god parents, and both were started by his villainous babysitter, Vicky. As much as he hated her for everything she did, Timmy did have to admit he did harbor a small, soft-spot for the redhead. After all, it was because of her that he got his fairies in the first place.
But this day was different. Timmy had been bunkered in his room, hiding inside an elaborate pillow fort in the event Vicky took a chainsaw to his door again. And yet, nothing. Timmy peeked out of his bunker, eyebrow raised as he wondered where Vicky even was. "Cosmo. Wanda. If I'm not back in an hour, come and find me," he told the floating fairies before hoping out of his fort. He cracked his door and began walking around the house cautiously, though when he made it to the 1st floor, he heard a quiet cackle come from the basement. Gulping, he ventured on, walking to the basement to see Vicky putting the final touches on a machine with a long tube connected to a vat of something he didn't recognize. He gulped, about to walk away, only for Vicky to grab his wrist.
"Going somewhere, twerp!?" She screeched in her usual tone before dragging him to the machine. He was strapped to a chair as the hose was forced down his throat. "Alright, twerp. Time for your ultimate humiliation; becoming a fat sack of lard for me to torture forever!" She cackled once more before twisting a valve on the wall.
In an instant, Timmy felt an oddly delicious substance begin to flow down his throat. Any resistance he had put up before slowly melted away as his eyes glazed over. Every gulp made his stomach bulge a little more. Within 5 minutes, the button on his pants popped off. Within 10, tears began to appear on his clothing, revealing his growing body for Vicky to admire.
The babysitter looked at the growing boy with glee as she ran a finger over his growing belly. "That's it piggy. Just keep growing and growing. Soon, you'll make the perfect boy toy for me to play with." After 30 minutes of the strange liquid getting pumped into Timmy, Vicky turned off the machine and pulled the tube from his mouth.
Timmy still sat, completely dazed in clothing that hadn't faired to well in the expansion, now tight and torn. His belly had grown the most, now the size of a beachball and nearly touching the floor from his sitting position. His ass didn't fair much better, now spilling off the chair he was tied to. His moobs had gained some girth as well, each now able to fill Vicky's hand easily. His limbs were caked in fat, enough to make moving them a chore. Timmy let out a small groan as the wooden chair collapsed from under him, sending the boy to the floor and forcing a belch out of him.
What happens next?
