That Time I Was Transfigured Into A Man-Eating Slime!

May 3rd, 1998

11:45 AM

Slughorn's Potion Class, Hogwarts

After the war, things had settled down back to normal, unfortunately no one seems to have matured. Hermione was working on a Saint Mungo's approved appetite stimulant potion for her final exam in the class, unaware Malfoy was watching her. He snickered as if his goons Crabbe and Goyle were next to him, but one died of fiendfyre and the other of choking on a turkey leg, he didn't care which was which.

"So, the mudblood bint thinks that she can do better than me does she?" Draco said as he pulled out a burning hot coal with potion tongs.

He tossed the coal into Hermione's potion causing the potion to switch from a stable supplement of clear color into a boiling volatile concoction of vivid dodger blue. Hermione turned over to look only for her cauldron to explode, coating her in the blue potion and fell onto the floor. She screamed in agony and writhed in pain as the potion sunk into her skin, students surrounded her as Malfoy grinned victoriously at the mudblood before Slughorn stunned him behind the back.

"You utter Bastard! You! Go get help! NOW!" Slughorn roared at a random Gryffindor who took off running.

5:43 PM

Medical Ward, Hogwarts

After being transfigured by an intentional potion accident, the only visible effect Hermione had was that her skin and hair were now a gelatinous substance in shade of bright blue. She could never return to the muggle world now, which means she won't be able to reconcile with her parents after she sent them to Australia. I mean, sure they disowned her and called her devil's spawn but she could always try to get back in their good graces right? Hermione frowned as she looked in the mirror Madam Pomfrey held up for her, she looked like the pudding they serve on Friday night!

"What did he do to me?!" Hermione asked as she cried, her slimy form lightly rippling.

"He sabotaged your potion with a burning hot coal, you're lucky this was the only side effect." Slughorn said.

"Will he be sent away for this?" Hermione asked… She didn't like the look on their faces.

"Unfortunately… no… regrettably Lucius Malfoy still has connections. You're legally a creature now..." Poppy said regrettably.

"What?! So he can ruin my life and get away with it?!" Hermione yelled, her body starting to bubble in anger.

"I'm sorry Miss Granger, but there isn't anything we can do… please, just sleep on it and we'll decide what to do in the morning." Poppy said as she tucked Hermione into the bed.

Hermione didn't put up much of a fight, not that she had a choice, and soon fell asleep. A few hours later, she woke up with her stomach audibly growling like a dog wanting to be put down as her eyes glowed white. Hermione then got out of bed and made her way to the kitchen.

"Must eat and poop. Then eat some more. Then eat while pooping…" Hermione said in a monotone as she walked to the kitchens.

2:13 AM

Kitchen, Hogwarts

Inside the kitchen of Hogwarts, every pantry and cupboard was opened and emptied. Everything from apple cores, animal bones, fruit peels, empty cans, empty boxes, empty jars, empty bottles, empty pitchers, and even candy wrappers were strewn throughout.

At the center of it all sat Hermione Granger who had easily put on a few hundred pounds. She was wearing only the hospital gown from earlier but it was more like an enlarged bib stained with food at this point. She had a large belly that spilled onto her lap that demanded more and more food as she greedily grabbed what little remained and shoving it down her jelly-filled cheeks with her rounded fingertips. Hermione audibly grunted as she slurped down an entire jar of mayonnaise, the contents entering her stomach and dissolving into becoming jelly on her well-rounded ass that grinded against the stool. The chair creaked and groaned as Hermione shifted her weight, planting her feet that have melded her toes together into a pair of shoe-like feet, firmly onto the floor.

"Mmmph... nghh.. still hungry!…" Hermione said out of desperation as she looked around.

"Well well well, the little half breed has made a pig of herself." Said a familiar voice.

The room lit up with torches as Draco Malfoy walked in grinning. Behind him was his father Lucius Malfoy with a license to kill Magical Beings. Hermione was confused at the rising feelings she had.

"There she is father, the mudblood who thinks she's better than us." Draco said, hiding under his fathers coattails once again.

"She's more pig than mudblood now. At least this will be easy to explain away, "Muggleborn Student dies from overeating after failed first year potion assignment.", Malfoy said.

"That was for my final exam you Nazi." Hermione said, dribble forming on the edge of her lips.

A head pushed its way against Hermione's belly.

"Where be's I?" The muffled head asked.

"Good Lord, is that a house elf?!" Asked a shocked Lucius.

"Uhh no." Hermione said, ignoring the creatures questions as she grabbed a frying pan.

"Can someone let Kindle out? It's rather dark in here!" The elf said before Hermione bashed it over the head with a frying pan.

"Ouch! Did Kindle deserve punishment?" He asked before getting hit again.

"Where is Kindle?!" He was hit once more, feeling faint.

"Mother?…" the elf asked before going limp.

"Well then. Avada Kedavra." Lucius said only for the spell to bounce off of Hermione and hit himself straight in between the eyes.

"Father!" Draco yelled out in shock.

Hermione licked her lips and stretched her arms over like Mr. Fantastic and grabbed the man's corpse before eating it. She grunted and struggled as the man slipped through her extended lips, his head and luxurious mop dissolving inside of her first followed by the rest of him. All in all this caused her to put on enough weight to break the chair, causing her to hit the floor with a resounding smack and sending her entire body jiggling.

"You ate my father! You monster!" Draco said before getting grabbed by Hermione.

"You know you always talked about yourself like you're some fancy purebred pig, I wonder if you'll taste just as good.~" Hermione said as she dragged Draco over.

Ignoring the formerly-underaged terrorist's kicking and screaming, Hermione lifted Draco into her mouth, feet first. He was lowered into what felt like a vat of acid and screamed as Hermione swallowed her and her friends' childhood bully. She enjoyed it more than she should have, but regardless, it was done. Maybe Malfoy WAS onto something though… The two of them were rather delicious.

"Okay… lemme digest this in the morning." Hermione said as she made the tumultuous journey back to the hospital room.

May 4th, 1998

7:00 PM

Black Lake, Hogwarts

The incident in the kitchen wasn't that well documented, Hermione realized. No one questioned why she put on 300lbs in the last 24 hours and why Draco and Lucius Malfoy were missing. At least she got to see Ron and Harry again, though the prior was a bit of an insensitive pig and broke up with her for her deformities and Harry looked drained from covering for Ron. She advised him to grow a spine and not bend to peer pressure and went off, feeling Harry watch her leave in confusion.

Hermione was snugly packed into her school uniform, her shirt was almost entirely unbuttoned except for one between her breasts and had her bulbous belly sticking out. She walked in an awkward way, as if she had a hippopotamus between her legs, her belly jiggling with each step. She grunted and groaned as she mindlessly waddled around before setting sight on a group of teens by Black Lake. The teens were making out with each other and sitting by a campfire, Hermione looked at their supple flesh as she drooled and fiddled with her fingers.

"Ooh! Teenagers! Mmmm~" She said before audibly drooling and moaning at the idea before snapping herself out of it.

"No Hermione! No more man-eating. Hogwarts students have enough trauma on their plate without me eating them." She said sternly before one Gryffindor yelled.

"Barbeque sauce fight!" She yelled before squirting the other teens with a bottle of muggle barbeque sauce.

All of the 7th years laugh and giggle as they spray each other down with the brown sauce. Hermione drooled as some whizzed past her and landed on a girl's cleavage. One hit a Hufflepuff student in the eye and sent him stumbling back into the fire. He landed on it and started screaming as he was burning alive.

"Wough! Ah! Aaaaghh! The flames are sealing in my juices!" The Hufflepuff stupidly yelled out, sealing his fate.

"I'll savor you!" Hermione yelled before running over like a morbidly obese batman.

Hermione picked up the boy by his right arm and left leg before taking a huge bite out of his back. The other teenagers screamed and ran off for their lives as their friend was left for the dogs, or in this case, hungry slime monster.

"Mmmm extra virgin~…" Hermione said, moaning and drooling as she shoved the screaming boy's feet into her mouth and slowly swallowed him.

"Ach! Agh! Ahhhh! Tell my friends I died kissing a girl!" The teen begged Hermione as a dying wish.

"No." She said bluntly before swallowing him whole.

May 5th, 1998

7:45 AM

Slytherin Park, Hogsmede

Hermione made decent work on the teenage horde that was by the lake, she got a few skinny dippers and merpeople. Her shirt was now completely ripped open revealing her boobs to the world, her skirt was almost fit to burst open. She waddled down the streets of Hogsmeade with no one looking any the wiser when she saw a gathering of purebloods in Slytherin Park. They were celebrating a "we got out of jail again" party with butterbeer and other party foods. Hermione hid poorly behind the sign and looked on in intrigue.

"Oooh, Butterbeer-Battered Death Eaters~…" Hermione said.

She slipped in and picked up a particularly portly death eater who was drinking butterbeer. Popping him in like a boiled egg, he looked and grabbed one of their fat children before eating them too as they gawked at him. They started to run away and apparate but two particularly fat witches were unlucky as Hermione grabbed them and gulped them down in quick succession. The two floated down into Hermione's gelatin-like stomach.

"What did we innocent Death Eaters ever do to deserve this?" The first woman asked.

The second one gave her an, "are you serious" look with her hands on her hips before dissolving into more jelly.

"Oh right." She said before dissolving too.

"Mmmmm~ Karma~…" Hermione said as she went to grab some more.

"HERMIONE!" She heard a familiar voice yell.

Turning over, Hermione saw Harry was there with his wand pointed at her. He was shaking with nerves as he had bags under his eyes. Hermione gasped and kneeled down to the level of the Auror Recruit, getting right up in his face.

"Well there's my favorite officer of the law, what's going on Harry?" Hermione asked.

"W-what's going on!? You're eating people!" Harry said.

"Harry, we both agreed back in the tent that death eaters are not people." Hermione said as she stretched her arm out to grab more death eaters.

"I can't let you do this Hermione! I have to uphold the law!" Harry said.

"What law? The laws that let Death Eaters run free and have Ron be able to pile all his work onto you?" Hermione asked.

"Y-Yes? How do you know that?" Harry asked, conflicted.

"Well it's rather obvious based on your facial expression and posture that you're exhausted. That and Ron was quite the bragger in his letters, how he gets to score on all the babes he wants. Damn toothpicks." Hermione said as she grabbed a similarly skinny witch and popped her in her mouth.

"R-Ron and you are still together?" Harry asked, confused.

"Together? Since when were we together? Me, and him? Hah! You have to be joking with me Harry." Hermione said as she broke out into a giggling fit, jiggling all over.

"But Ron said-" Harry said before being interrupted.

"Ron can't say anything unless it's out of his arse. All feelings I might have had for the little twat died when he left us to die in the Forest of Dean while we were running from these twats." Hermione said, showing Harry a screaming snatcher and swallowing him whole.

"B-But you're eating them… it's cannibalism" Harry said.

"Malfoy declared me to not be human, it's not my fault his words are law when he's got enough gold poo to fling at the wizengamot." Hermione said as she looked him in the eyes with a warmth of love.

"I-I see… so what would I get in return for looking the other way?" Harry asked her.

Hermione mockingly gasped and held her hand up to her chest, her bosom sagged to the ground.

"Harry Potter the golden boy wanting to take a bribe? Oh the humanity!~…" she fake-swooned as she giggled.

"Well I'm too tired to stop you… and I don't wanna stop you either when you're doing the public a great service." Harry said as he yawned.

Hermione grinned and rolled onto her buttocks, smothering a good 10 death eaters who tried to go around her and dissolving them into ass jelly. Hermione grabbed Harry and placed her on top of her belly, his feet slightly sinking into it like a trampoline.

"Well then why don't you just take a good old nap while I clean things up~…" Hermione said as she patted her belly, sending ripples down.

Harry shrugged and lied down, bouncing a bit while he bounced up and down a bit.

"Oh you're so soft!~…" Harry moaned out as he reclined.

"I can control my viscosity and acidity, so don't worry about falling in or anything while you sleep.~" Hermione said as she grabbed another death eater.

"Yeah I'll… ~yawn~ I'll do that…" Harry said as he passed out on the softest bed he ever slept on.

Hermione then devoured each and every person present at the park, whether or not they were present for the death eater party. People screamed, people begged for their lives, but none were spared from the fate of ending up on Hermione's thighs. Now she was about large enough to fill up a city street and tower over the two story buildings. No one outside of the two of them really called attention to them either, how bad were these sheeple at pointing out trouble?

"Must eat more dumb wizards… Thank God I'm in England," Hermione said seriously as she scouted out the perimeter.

She saw Moody with his trunk entering a pub, but stopping to harass the drunken Mundungus Fletcher.

"And that's my ticket out of here~..." Hermione said, licking her lips as Harry woke up from her stomach growling.

"Hermione? What'd I miss?…" Harry asked.

Before he recognized anything, Hermione picked him up and planted a kiss on his face and placed him down into the park.

"Sorry Harry, but I've got a dinner date in Diagon Alley~…" Hermione said as she shuffled away with a sway in her colossal hips.

Harry stared in shock and awe before putting a hand up to where she kissed, while it didn't burn it felt all tingly which was nice.

Getting over without anyone noticing, Hermione grinned and popped it open before slithering into the trunk and somehow managing to fit. Luckily, there were all sorts of criminal suspects inside to tide her over until Moody made it through the floo.

"In ya go Fletcher!" The one eyed wizard said as he forced the pickpocket into the trunk.

He ignored the wizard's screams as he was eaten alive by Hermione and grabbed the trunk's handle. He grunted as it felt much heavier than it did earlier, so he started dragging it against the road. He huffed and puffed as he entered the tavern and went through the portal to Diagon Alley. When he made it through, he wiped his brow, unaware the trunk had opened up and a giant blob was pouring out of it.

"Damn trunk! Maybe I am getting too old for this. Maybe I should retire for good this time, go to bora bora or maybe Thailand- hey!" Moody said as he was picked up and eaten by Hermione.

People screamed and panicked before running off as Hermione went to get more food, leaving Moody's eye and peg leg behind in her slime trail.

May 5th, 1998

11:30 AM

Diagon Alley, London

A crowd of people were running from the now building sized Hermione. She swayed and waddled as what was left of her legs now melded with her gargantuan belly and hips as she squeezed herself between the buildings. As this happened, the radio on wizarding wireless was playing some weird ripoff version of "Baby Got Back" that Hermione was getting into.

"I like! BIG! Guts and I cannot lie!"

Auror John Dawlish was shooting curses at Hermione before being picked up and swallowed whole.

"Double chins with the chafin' thighs! When a dude walks in with the hanging jowls, my stomach starts to growl! — I'm getting hungry "

Hermione breaks her hand through a window of the Leaky Cauldron and pulls out a drunk 400lb wizard and she eats him before looking over at Florian Fortesque's.

"So I masticate! Chompin' on the overweight!"

She pulls out four customers with large ice cream cones and pops them all in her mouth before chewing and swallowing.

"I eat fat people for days, like potato chips by Lays!"

She notices an autograph signing with Ludo Bagman and his team the Wimbourne Wasps. She grabs the four fat men who haven't died to their injuries or heart attacks and shoves them all into her mouth at once before swallowing.

"Try to eat just one but it can't be done, I gotta eat a ton!"

"Baby likes fat!"

She glances over and sees Madam Malkin's and reaches inside. There she grabbed a fat wizard and two chubby witches who had come in for robe extensions. She then reaches in for something, her belly jiggling as she did so before pulling out a large set of ocean blue robes with a pod of animated whales moving across on them.

"Baby likes fat!"

"Hehehe! I used to think these clothes were for fat slobs." She giggled out as she posed in the poorly fitting robes, looking at how they flattered her rump.

May 5th, 1998

11:30 AM

Diagon Alley, London

Concerned shoppers watched in horror as aurors tried to take down the gargantuan blob, who tiredly shifted her weight over to feed. Hermione's legs were completely gone as she slithered back and forth like a snail, huffing and puffing as she built up an appetite. Her boobs were still buoyant but were jiggling with every exhausted breath and spell hitting them. Aurors on the front line were trying to take her down with spells, nearby the news played on witch wireless.

"It's blob rule in Diagon Alley! And to make matters worse we're being attacked by a fifty foot Toad." The newscaster said.

Earlier today, a cauldron bottom broke and a potion spilt on Umbridge causing her to grow to 50 feet while they made a cure. She now leaned against a building unamused with a torn up banner for a, thankfully, full-body dress.

"Everyone's paying attention to the mudblood." She bitterly remarked.

"You're frightening in your own matter" replied a voice from nowhere.

"Thanks invisible fudge." Umbridge said as she held up her hand.

Suddenly the two of them were pulled into hermione's vast adipose. Screaming as Hermione forced them down her throat and digesting them to put on another thousand pounds easily. People screamed as she tightened up against the buildings enough to crack the glass in the windows. Hermione peeled off the roof to the Knight Bus like a sardine can and picked out two people before eating them, she then ended up grabbing Stan Shunpike.

"Uhh… I didn't do anything wrong?" Stan said before his head was bitten off by Hermione and the rest of his body tossed down her throat.

"Hermione Granger! Surrender with your hands up!" Yelled the chief Auror.

Hermione looked down and saw every Auror lined up ready to fire spells at her. Ron was flirting with some witches on the side, talking about how she dated him until she let herself go. She saw in the back, Harry and Slughorn were talking.

"So what is your plan?" Harry asked.

"Well, we hope to have isolated the cause of this transformation and made a potion to reverse the effects." Slughorn said as he held up a liquid red potion.

"Will it hurt Hermione?" Harry asked.

"All it should do is turn every part of her that is slime back to normal. So I presume so." Slughorn answered.

Ron walked over and snatched the bottle.

"So this is what will make that fat slag back to normal eh? Alright, guess it's up to me to save the day again." Ron said as he chucked the bottle at Hermione.

"Wait!" Slughorn yelled but it was too late.

The bottle hit Hermione's belly, sank inward like it was on a trampoline, and then bounced off before smashing on Harry's head. He screamed as he was doused by the cherry red potion as it sank into his skin and hair. He hit the dirt and writhed in pain, coughing as he struggled to stand.

"Eh? You alright mate? Anyways as I was saying-" Ron continued to flirt over the frustrated grunting of Slughorn.

"You… -coughs- daft… -coughs- BASTARD!" Harry yelled at Ron in between coughs.

Harry got up, revealing he was now a red slime like Hermione. In his anger, his uniform and glasses dissolved into his acid.

"First you abandon us in the forest of Dean, then you make me do all your work while you take all the credit as an Auror, and now you ruin Hermione's one chance of turning back into a human!?" Harry yelled at Ron, boiling mad.

Ron was trying to back away, hiding behind his floozies. Harry kept ranting about Ron's ineptitude until he was cut off by a raucous belch that came from Hermione. The street-sized blob jiggling and wiggling as the belch came to a stop, now she was on her front again, looking down at the two. The other aurors all were petrified in fear as Hermione looked at them all like appetizers, especially Harry.

"Well, well, well, who knew red would look so good on you Harry~…" Hermione teased, eying Harry's new nude slime body.

"Oi! Take your medicine you whale!" Ron said.

"She can't because you wasted it Ron! And now you made me into one just like her!" Harry said, frustrated with him.

"Not my problem." Ron said as Harry boiled over.

"It's not so bad Harry, being a slime and all." Hermione said to him, calming him down.

"How could this not be bad?! I'm a freak!" Harry said.

"Yeah, but you get to eat whatever and whoever you want and can seemingly get as big as you want without any consequence!" Hermione said as she picked up a pedestrian and swallowed him.

Harry's stomach then growled as he looked at Ron. It was no secret that the Auror Weasley wasn't the most in shape, fattening up in Shell cottage while the two of them starved. Even the floozies he was with had bountiful breasts and meaty thighs. Harry drooled and figured, "if I can't beat em, eat em." He lunged at the three of them and swallowed them all at once, the three quickly dissolving in his ballooning stomach.

"Oh not another one!" An Auror said before being grabbed by Harry and popped in his mouth.

Harry soon ate through all the aurors in England and groaned, they were unfortunately low on budget. He then ran into the shops, people started screaming as Harry cleared out all the shops of their stock and customers alike. After a few more hours of this Hermione grinned at Harry with half-shut eyes, they were now around the same height and size with Harry exhaustedly breathing. She then pulled the Blob who lived into a kiss, both slimes enjoying the taste and texture of their new tongues before pulling appart not due to a lack of air, but Hermione grinning.

"Phew!… That felt amazing…" Harry said panting, his red gelatinous body pulsating.

"Wanna go clear out knockturn alley for seconds?" Hermione asked with a seductive smirk.

"Oh fuck yes, but er- how do we know they haven't run off yet?" Harry asked.

"They're idiots. Now c'mon, you head that way and I'll slither Through the sewer ducts to the other end. We'll both meet up in the middle and snog some more.~" Hermione said with a grin as she lifted up a manhole cover.

As she drained down the hole Hermione couldn't help but thank Malfoy. Because of him, she got to eat whatever she wanted, got together with the love of her life, and got to take care of Britain's biggest pest problem- Wizards. Of course, eventually they'll run out of them and may have to find alternative food sources with muggles and other magical communities, and then the Earth, and Mercury, Mars, etc.

Hermione was always a go-getter, even as a slime...
