*Urp* A burp escaped Harry who then let out a groan and rubbed his bloated belly. He was surrounded by empty candy wrappers and food crumbs. Though it was something that Harry was getting used to, his sixth year was strange, people were like weirdly nice to him, way too nice. Even Snape and Draco didn't even harass him at all though they seemed to have kept their distance from Harry. Professors would pass him even if he didn't do good on tests, people he didn't know wanted to be his friend and all the treats. Harry was sure he could just eat all the food peo[le gave him and not have to eat at the Great Hall. Though of course, he did both since Ron and Hermione were always pestering him to go to the Great Hall then shove food in his face. Every day he was going to bed stuffed, and it was starting to show. He had a small belly poking from his shirt, and his chest was sagging a bit. Though he'd probably lose all of it since he was going back to the Dursleys for the summer, who would probably starve him. If he knew anyone that wouldn't be nice to him it was them. And it sucked he had to go home alone since Ron and Hermione since Ron and Hermione went to Romania to see Ron's cousin Charlie.
A slow creaked was heard in the hallway of the train, as Harry turned his head to saw the old woman rolling the trolley car. She stopped at Harry's booth, grabbed some candies and placed them in the seat next to Harry, "Compliments from the trolley for a growing boy" she said as she continued on her way. Harry collapsed in his seat and groaned he was too full to even think about eating again.
Of course, Harry was unaware that this was all happening due to a botched charm that a Death Eater had cast on Harry since he infiltrated the Ministry of Magic, it was a dark charm that made other people hostile to the person it was cast on, though it did the opposite and had people befriend the user though also it also caused people to passively want the charmed person to gain weight as well, and Harry had no idea that this would also affect the Dursleys as well.

Harry made his way home walking up 4 Private Drive, while also dragging his suitcase to the door. He wasn't looking forward being back, it was hell, it was always hell. Though Harry knew it wasn't something that could be avoided. He knocked on the door waiting for Vernon or Petunia to answer the door and look at him with disdain, or worse Dudley to open the door and harass him. Harry knocked on the door. A few seconds later the doorknob twisted and swung open, revealing his cousin Dudley. Harry saw the Dudley did look bigger than the last time Harry had seen him, which wasn't a surprise since Harry's aunt and uncle spoiled him. But before Harry could process anything else, he saw Dudley's face changed to the excitement, "Harry!" Dudley shouted and then wrapped Harry in a bear hug. Dudley's wider frame making it look his body was engulfing Harry's.
Harry was shocked the last thing he ever expected was to see Dudley be excited to see him... or actually hug him. "It's... nice to see you at Dudley..." Harry said, still weirded out by what was happening.
Dudley put Harry down and ushered him into the home, "It's so glad to see your home, Mum and Dad were all excited to see you, but they had help Aunt Marge with something, but they'll be home soon." Dudley said. Harry's eyebrow raised hearing that his aunt and uncle... missed him. This day was getting weirder and weirder. Though Dudley didn't seem to notice Harry's expression. "And look at this" Dudley said giving Harry's belly a grab, making Harry blush. "Man looks like you enjoyed your time at that school, finally becoming a man" Dudley joked.
Harry politely removed Dudley's hand from his belly, he was having a hard time accepting what was going on but he didn't question it for now after all this was way better than being bullied by his cousin. "Yeah it just kinda snuck up on my I guess" Harry took a better look at his cousin, he was correct Dudley had gotten bigger since his time away. Dudley's belly clearly straining against his t-shirt, and there was no arguing his cousin's moobs had gotten puffier as well. But Harry's belly let out a growl, Harry was slightly shocked he was hungry again.
"Oh right you must be starving after the long trip home come on," Dudley said as he leads Harry to dining room, and in there was a giant spread of food, the entire surface was covered. "Mum prepared this for you when you could home, just for the two of us, now come on before I only leave you scraps!" Dudley said excitedly as he rushed to the table, with Harry following his cousin to the table as they begin to eat to their heart's content.
