Harry Potter was very new at Hogwarts and he hadn't had much experience in school as a child yet, but if there was anything that he understood well enough, he knew that there was always a way to warm up to the adults. He didn't want the professors of Hogwarts to hold a grudge against him like the Dursleys did. He was a good kid with an equally good heart, he just wanted to learn magic and find his way in the world after being treated like a burden for so long. While he still didn't know much of anything about this strange world of wizardry yet, there was still one thing he knew off the top of his head: baking.
 
 
Of course, the Durlseys had forced him to assist plenty of times with cooking before, which was how he learned his way around the kitchen for the most part. He didn't know how to do a whole lot but he knew how to bake simple kinds of sweets. He had already become acquainted with Professor McGonagall, who is the head of Gryffindor House, and he knew that he wanted to be on her good side. She would be the one more likely to decide whether or not he'd have to go back home to that horrid family more so than anyone else here.
 
 
So when he had some free time, Harry went to work after borrowing the Gryffindor kitchen for a while. He wanted to create some pastries for her. Harry knew how to even fit jam into the pastries. He always sprinkled some white sugar crystals on top too. If there was anything that he had learned from his aunt, it was at least how to improve on the presentation. Harry never baked for one person before so he simply stuck to what he knew and made enough for what would usually be eaten by a group of three people...he didn't typically get to eat what he baked in the Dursley household. He made a few extra on the pan simply for the sake of saving a few for himself too.
 
 
However, by the time that everything had finished baking and they had developed that delicious golden brown coloring, Harry decided that he might as well just finish making everything for Professor McGonagall instead. She was probably going to be pretty hungry after all the work she had to do, both as head of house and as Deputy Headmistress. Putting up with so many students, it couldn't have possibly been easy. He wanted to do what he could to make her happy. That was just the sort of kid that Harry was.
 
 
Professor McGonagall was a little taken aback at first when one of her students suddenly appeared at her door with such a package. "You are...Harry Potter, aren't you? What are you doing here at this time of the night? You should be preparing for bed already with the other Gryffindors, young man!"
 
 
"I understand and I am sorry, but I wanted to make sure I was able to give this to you first. Please, Professor McGonagall, help yourself to these baked goods I had prepared for you. I only just wanted to give these to you to thank you for all of your help thus far. I would have never been able to get here...and be part of Hogwarts...if it wasn't thanks to people like you."
 
 
Professor Minerva McGonagall was certainly touched by the young man's insistence to repay her. She didn't expect him to do anything of the sort but his willingness was highly appreciated. It only made sense for her to take the treats; it would have made her look like a rather terrible House Head if she had decided to turn them down. She thanked the young wizard and then sent him off to go back to his dorm. She took the treats into her office and sat them down on her desk.
 
 
"I suppose I might as well try them now. I wouldn't be a good teacher if I couldn't assist my students in improving. I'll see what it tastes like and make a note on what to inform young Potter to do for his next batch. I'll also need to come up with a proper excuse for what I would end up doing with the rest of them. My goodness, he really did bake so many all for me!"
 
 
Professor McGonagall took a bite of one of the little pastries. It had jam right inside of it, a blueberry jam to be precise. Her eyes widened and her eyebrows raised in surprise and delight. Just to make sure she wasn't somehow mistaken, she took another one and ate it too. Again, that blueberry jam. So sweet and so strong yet not too strong where it overpowers everything. McGonagall could still taste the butter too. She grabbed a third one and ate it as well. She didn't wish to spoil herself for dinner beforehand, but she couldn't help it when everything was so tasty. She couldn't believe how it was actually so very delicious like this.
 
 
"What in the world? Did that boy use magic to make these? He barely started the school year and didn't even know magic before coming here, so he couldn't have possibly been able to do this? This boy's talent might lie more in the kitchen than in the classroom! Hmph!" McGonagall ate another despite knowing that she shouldn't. There didn't seem to be anything wrong with that. It felt so...right...to be able to just eat these and relax.
 
 
Minerva did not really think about it. She continued to eat without questioning it at all. Before she realized it, by the time she had finished signing her last contract and sent them off in the talons of her personal owl, McGonagall had already eaten every one of the sweets. She licked her thumb to catch some jam still clinging to her digit. She was genuinely impressed. Never before had she eaten sweets so good. Is this how they bake them in the Muggles' world? Harry might have brought a unique viewpoint after all now that he's been admitted.
 
 
McGonagall stared at the empty box in front of her. She wondered if she could ask Harry Potter to make those snacks again. It would seem imprudent of her as a teacher to be making such requests from a student, especially a first year student, but...it had just tasted SO good. She didn't think that she could rightfully turn the other cheek and ignore it anymore. The perfect collection of flavors! Somehow that boy had been able to bring out tastes from those ingredients that the experienced, long-running chefs have never achieved before.
 
 
McGonagall took off her glasses and lightly wiped away at her temple with a napkin. "I should think this over some more. A teacher and witch of my standing should always be exceptionally considerate of her behavior. I shouldn't try to make a student do these sorts of favors for me...but my goodness, they were so DELICIOUS, though!"
 
 
Professor McGonagall had not initially intended to signal out Harry Potter among all of the other students. After all, it would have not been appropriate for her as the overseer of the entire Gryffindor House if she started playing favorites. She knew this well enough, but one day, she still needed to speak with the boy to see what it was that he intended to learn from Hogwarts. She tried to schedule one-on-one meetings with every student so that she might better understand their wants, their needs, their goals. Harry seemed a little meek when he had to meet with McGonagall again, the first time that they were speaking since he had brought her those snacks over a week ago.
 
 
"Mr. Potter, I want to hear with your own words how you feel you've been adjusting here at Hogwarts. Do you feel like you are beginning to comfortably adapt?"
 
 
Harry didn't really know what to say. He shrugged, trying to explain that he felt like he was in a place that seemed more fitting to him than expected, but he still didn't yet know what he actually wanted to do and try to learn. McGonagall rested her pointed chin upon her crossed hands, thinking deeply on this matter. She wanted to make sure that Harry Potter was comfortable in his brand new environment. As it just so happened, she knew exactly what to suggest.
 
 
"If you're still not sure what to do, you should focus first on the things that you are most comfortable with. I still recall those pastries you had made me before. I know you meant it only as a simple gesture of gratitude, Mr. Potter, but those pastries were truly more impressive than you might have realized. You have a potential talent in baking! If you enjoyed it, you should try to do it again and put your focus into that, to better help you understand what it is that you want to achieve here in Hogwarts...and if you are willing to share, I would be happy to assist you as a taste-tester. A-Along with the other students, of course!"
 
 
Minerva really hoped that she didn't come off too obvious. She ultimately wanted her student to be able to succeed more so than anything else. Her own appetite surely didn't play any role in anything. Just because she really would have liked a chance to eat the young man's baked goods again didn't mean that much in the case of her decision. She would have sworn it on her very wand, but...that would have still been a lie.
 
 
"I'm so sorry, Mr. Potter." McGonagall murmured under her breath as she watched him leave. She would have to give him some extra credit for going through this kind of effort, because he deserved that much for trying so hard.
 
 
Fortunately, Harry thought that the professor's suggestion sounded like an idea he could agree with. He returned to the kitchen posthaste. With his wand, he was able to summon utensils and ingredients like butter and eggs right into his hands. He tried to put his new magic ability to the test by using it to bake the food. When the chance arrived, McGonagall was right there to be the first one to try his newest creation. She wanted to be able to taste it before anyone else. She'd waited this long and resisted doing this any sooner up until this point.
 
 
Yet that first bite just didn't hit with the same explosive flavor as before. It was strangely...muted, somehow? It was difficult to describe but it had this 'offness' about it that it simply didn't match what had been shared before. Harry openly admitted that he didn't think that he had made the pastries as good as the last time, and McGonagall was unfortunately inclined to agree.
 
 
"I think next time, I'll just go back to baking with my own two hands. Seems like it comes out better somehow." Harry remarked. McGonagall did not really think that she, as a teacher of magic, should ever encourage a student to do this, but she genuinely believed it would be the best, or so her stomach had decided first and foremost.
 
 
Who would have expected such a woman like her, who had maintained such a prominent presence within the wizarding world as a scholar and a teacher of renown, would have a secret sweet tooth? She had never, ever indulged in the manner that she was about to, however. It was like something had finally clicked inside her head to make the change happen. She never would have imagined it was because of that young Harry Potter that Headmaster Dumbledore had told her so much about prior. She would have believed something more from the boy who had been both so blessed and so cursed as him, but...McGonagall hadn't been prepared for it to actually affect her own waistline.
 
 
She tried to convince Harry that he should focus his baking interests for some of the upcoming holiday events, as both Halloween and Christmas parties were extremely popular and quite chaotic at Hogwarts. Limiting the work seemed like a good way to keep things more balanced for both him and for her. Yet as soon as the good pastries were back in her hands again, McGonagall couldn't control herself. She needed to keep eating more, more, MORE.
 
 
"Well, if you ever happen to find the free time to do so, Mr. Potter, I would not mind...I mean, I would appreciate...er, what I am trying to say is, I think you should continue to practice your baking along with your magic. You would be able to make an incredible patissier one day if you wished to open your own bakery."
 
 
Harry understood perfectly, or at least he thought he did. McGonagall was simply trying to encourage him, that much he could gather. So, feeling more encouraged than ever before, the young man began to put his all into his baking as much as he did his magical training. His friends from Gryffindor didn't seem to mind it if he wanted to spend more time in the kitchen. It was a little odd that he had become such a favorite of the House Head, though. She had never been known for picking favorites before in all of her years serving as a member of Hogwarts staff. Harry had been the one to change all of that.
 
 
McGonagall ate and ate and ATE. She'd never eaten this much before in any extended period of time. She usually kept herself to very small meals, she ate like a bird, because she was often too preoccupied with her responsibilities and obligations to be compelled to consume more. Yet those pastries had changed everything for her. When she ate, she ate until she had cleared off the entire plate or emptied the whole box. She was obsessed with these sweets on a fundamental level that ordinarily should have been impossible to achieve for someone as steadfast as her.
 
 
Professor McGonagall started to notice some changes, little ones at first that gradually turned into big ones. She had started to gain weight. It showed off first around her waist and thighs when her long skirt didn't seem to fit as well as it used to. It was snugger, tighter, more constrictive than expected. It caught her off-guard one morning, forcing her to replace it with a different belt she never normally used. McGonagall looked at herself in the mirror, turning left and right. She MIGHT have had a belly now but it wasn't entirely clear for her to tell yet.
 
 
"Well, I must simply be a little bloated still from last night's dinner. Yet, all of those sweet rolls. Hmph, I should never have allowed Albus to put all of those extras onto my plate!"
 
 
McGonagall liked to believe that she had entertained the old man by eating all of that food, but she had actually done it just because of how hungry she was. Those sweet rolls didn't come close to matching the incredible, delectable flavor brought about by Harry Potter's baked goods, though. McGonagall had to 'wash out' that undesired taste by eating another...dozen...of Potter's Pastries before she'd gone to bed the night before. She had absolutely no intention of accepting the fact that she was deliberately overeating.
 
 
The professor grew gradually fatter. Her lack of preparedness for this drastic change in her figure left her completely unable and perhaps even unwilling to do anything about it. She just focused on feeding her consistently growing appetite rather than dealing with the developing consequences. McGonagall found her stomach still continued to give her problems. It became gradually more distended. It was so soft to the touch, not to mention so squishy. It was all her, though. None of it was a pillow or some kind of puffed up fabric under her dress, it was all HER. That could easily seem quite frightening for most people.
 
 
Minerva McGonagall, however, did not have time to afford to work on bettering her body and shedding these unwanted pounds. She was the Head of Gryffindor House, which meant that she had several dozen young students of varying ages to watch over. She had Transfiguration classes that she needed to spare an extensive amount of time to prepare for and then subsequently teach. There were plenty of other important tasks that she needed to accomplish under the orders of Headmaster Dumbledore as well. Simply put, her days were never not packed from first morning light to the moment that she shuts her eyes for bed.
 
 
McGonagall managed to pack on weight faster than most because of the numerous stresses and rigors of her everyday life. Her stomach grew larger and heavier, soon drooping right over her waistline in the form of a pudgy paunch. Her chest filled out more too, though not by very much. Her backside and hips, on the other hand, saw fit to begin flaring outwards by a great deal. When she sat into her chair next to the Headmaster's in the dining hall and discovered, much to her humiliation and horror, that her ass was too wide to fit between the chair's arms, that was the point where she felt something was certainly mistaken.
 
 
There was a heaviness on her body all over and she had to move with a slower and more awkward gait than she had been prepared for. Everything was more clear than it had ever been before. She could tell that she had gained weight. The older woman did not even need to think about it. To deal with the stress of this reveal, she ended up eating even more. The gluttony was nearly impossible to restrict, because it was simply always tempting her at almost all times of being awake.
 
 
McGonagall continued to put on more weight than she could handle. Her face sprouted a second chin over her thickened neck. She became out of breath more easily. She did everything that she could to avoid riding a broom in front of anyone, because she was frankly afraid that she was getting too fat to be able to ride one without fear of snapping it in half underneath her. Her stomach and backside continued to extend further out from the rest of her body as the number of pounds rapidly ticked higher and higher every day. She COULD have done something about it, but every time she ate those pastries made by Harry Potter, she would fall right back into the bad habits all over again.
 
 
"Professor? Professor?" A knocking on her office door as well as a familiar voice calling out drew her attention. McGonagall didn't want to answer the door at first because she was already able to smell the delicious aroma of those pastries. However, to ignore a student would once again be improper behavior of a teacher, so McGonagall begrudgingly rose from her desk to see what it was that Harry Potter wanted. She didn't like how her belly knocked into the desk as she stood; some of her fat roll had to be left jutted underneath the table because it had no more room otherwise.
 
 
As she waddled to the door, she tugged on her outfit some more to stop making it pinch and squeeze her in places that she preferred it not to happen. She felt her underwear dig especially deep into her backside. Her belly bobbed up and down with every lethargic step. She almost made it to the door before she had to briefly pause and rest against her bookshelf, putting her hand on it to support the rest of her portly body. McGonagall was very glad to know that she could do most of her work alone in the privacy of her office. To be seen struggling like this in front of the student body, or worse yet her contemporaries, would have been...she winced just trying to finish that thought.
 
 
In any case, McGonagall opened the door just a crack to look at Harry Potter. The young man smiled up at her with that familiar box already in his hands.
 
 
"What is it, Mr. Potter?" McGonagall tried to be very cautious about how she opened the door. She stepped to the right just a little more to keep some of her belly from peeking out.
 
 
"I was worried when I had heard that you had been feeling unwell lately, even to the point that you had to have a substitute take over the Transfiguration class instead. I wanted to make sure you were alright and so, um, I brought some more of those jam-filled breads that you've enjoyed so much. Would you like some?"
 
 
Harry remained positively clueless as he offered the box to her. McGonagall bit down so hard on her lower lip that she nearly broke the skin. She had used a spell to find out her current weight last night and she had found that she weighed almost half as much as a troll! This weight gain of hers was NOT something she could allow to progress any further. If she knew what was best for herself, the professor would have turned down the offer of sweets posthaste.
 
 
However, that hopeful look in his eyes, that glint of the youthful innocence of a boy who only wanted to do right by others...there was no way that McGonagall could possibly turn him away. If only she had not been such an established and dedicated educational professional!
 
 
"Th-Thank you for that, my dear boy. It is very kind of you to be thinking of me in my time of discomfort." McGonagall accepted the box and took it away with her into the office. Before she shut the door, she hastily called out to him, "I am relieved and proud to see that you have found yourself a comfortable setting here within Hogwarts, Mr. Potter. I am confident you will continue to prove yourself as a capable student."
 
 
McGonagall tore open the box before she'd even sat down at her desk again. She shoved one of those sweet delights straight into her hungry maw. It was just as good as she had hoped! She let out an actual mewl of delight. Her softened paunch was pressed into the edge of the table as she leaned over it. She didn't know if she could sit down immediately because she needed to eat another treat first. Her incredible hunger would allow her no relief until it had been satisfied first and foremost.
 
 
"Oh...I'm just so hopeless, aren't I...ahh, it's all so GOOD...I never thought that food could be more powerful than any dark wizard's curse!"
 
 
McGonagall spent the next hour just stuffing her face rather than continuing with her paperwork. Her stomach grew so full and tight that it felt like her robes' belt might pop straight off. These pastries were filled with alternating jams, strawberry and raspberry. She couldn't get enough of them, especially not the powdered sugar added on top. Somehow they were getting better and better, that boy's baking skills!
 
 
McGonagall must have looked like such a pig shoveling these snacks into her maw as her body clearly was too large for her chair. That being said, her seat started to let out some very ominous creaking sounds underneath her. Despite that, the professor just kept on eating. When her belt snapped and her chair shattered underneath her at the same time, sending her plummeting to the floor, the one and only thing that Professor Minerva McGonagall could think about was whether or not there would be more snacks for her in the near future. She let out a very satisfied belch as she laid there on her office floor.
