"Hey Big D, enjoying your spinach?" Harry sneered. In front of him were three McDonald's bags that he had bought specifically to eat in front of his cousin, who had to settle for some miserable spinach.
Dudley was a big kid... A very big kid. Too big for his school uniform, in fact, and the school nurse had already given his parents a warning: their son couldn’t keep growing at this rate, or his health would be in serious danger. Besides, Smelting's had already run out of uniforms in his size, so unless Petunia sewed him a new one... finding one was going to be a challenge.
After Dudley’s diagnosis, his parents had gotten very strict with him: they put him on diets and even signed him up for boxing to help him shed a few pounds, and for the first time, the spoiled Dudley had limits. And he didn’t like them.
And Harry? Ever since starting at Hogwarts, the world had certainly gotten much better for him. Thanks to his aunt and uncle’s fear of magic, the endless hours of chores had stopped, and the cupboard under the stairs had been replaced by Dudley’s second bedroom. On top of all that, Harry was now famous and RICH, rich enough to buy all the food he wanted. Ever since returning from Hogwarts, his diet had basically consisted of two things: sweets and fast food.
But, of course, Harry hadn’t bought those three burgers just because he was hungry.
For the first time, the Dursleys had imposed limits on Dudley, and Harry was determined to take advantage of that to give the blond a taste of his own medicine. Whenever he could, Harry would gorge himself in front of his cousin, wolfing down more than considerable amounts of food that Dudley was forbidden to eat. When he wasn’t doing that, he was lying on the couch or in his room watching TV or, in general, being lazy. Naturally, this had had some impact on him; Harry was no longer exactly underweight: his face looked a bit fuller, and his arms had gained a bit of bulk. It wasn’t anything too significant, after all, Harry had always been very underfed, but the extra weight was definitely starting to show.
Dudley stayed silent as Harry devoured his burgers like a starving pig, washing everything down with a few gulps of his giant Coke and burping from time to time. He had never seen his cousin like this but, then again, he’d also never seen him eat this much food.
Within minutes, Harry had finished his entire meal and let out a loud burp. "That was sooo good. Too bad you can’t eat this, fatty," the dark-haired boy mocked, as he got up and tossed the wrappers and boxes in the trash, before heading off to his room for a nap. Wait... Was that a belly Harry had down there? "It can’t be, right?" Dudley thought.
The big blond kid remained seated at the kitchen table even after Harry had left. And, defeated, he finally gathered the courage to bring a spinach leaf to his mouth, stifling an expression of pure disgust.
