A/n: 2nd part is up; I hope you enjoy!

When Harry and co. went to their beds and fell asleep that that, something happened, something big.

As Harry slept under his covers that night, he dreamed of escaping the oppression of his relatives, for good. It didn't matter how he did it, but the newly introduced growth spell inadvertently put the image in Harry's subconscious and therefore dream that he grew big enough to crush his aunt, uncle and cousin, bursting forth from his home and escaping that wretched place.

Little did he know though, that those thoughts of growth were coming to fruition.

Throughout the night, the oversized pyjamas he called his own seemed to shrink as his body expanded slightly. His trouser legs ever so slightly inched their way up his legs, crawling across his skin as his sleeves did the same. From his waist where the bottom of the shirt laid, it began to rise up to, exposing his stomach to the elements as Harry's feet began to grow out from the bed and dangle out of them.

All the while Harry slept sweet soundly, oblivious to the changes that were happening to him.

As Harry's eyes creaked open in the morning, a muffled voice could be heard gracing his ears.

As his head turned right, his eyes gazed upon Ron, looking at him with a completely gobsmacked face, his jaw dropped and his eyes as wide as dinner plates.

"R-Ron, why are you looking at me like that?" Harry groaned as he stifled a yawn.

'Wait, did I sleep in my tight clothes again?' Harry thought to himself as he felt restricted as he moved, his clothes latched onto him tightly.

Ron said nothing as he was still tuck in that strange daze of his.

When Harry turned his head forward as he lifted off his covers, he could definitely see why Ron was shocked.

His feet were dangling off of the edge of the bed as his clothes had tightened around him. His pant legs were up above his knees and his sleeves were before his elbows and they clung tightly to his skin. thanks to how tight it was his entire stomach was exposed and only his chest remained covered. The strange thing was though that with his exposed stomach came a noticeable six-pac which adorned his abs and when he looked at his arms and legs the seemed rather toned in muscle as well, although not by a lot.

"O-oh Merlin!" Harry gasped in fright as he sat up. "Ron, c-change me back!"

"I don't know how!" Ron exclaimed, snapping out of his stupor. "I wasn't paying attention, so I only listened on how to grow things!"

"Damnit!" Harry grumbled as he rushed out of his bed and stood up, only to find the top of his head banging against the roof. "Ow!"

'We need Hermione!' Harry thought. 'She can change me back!'

"Ron, we need to see Hermione." Harry said to him. "At this size I don't think I could use my wand properly, so you'll have to grow my cloak."

Ron nodded as Harry shuffled under the bed, having difficulty due to his enlarged hands until he dragged it out with the tips of his fingers.

"Growkus!" Ron cast with his wand as the cloak began to exponentially grow in size until it stopped a few seconds later.

When Harry grasped the cloak and flung it over himself, he noted it was just the right size for him as he walked to the doorway.

"Let's get going." Harry motioned for Ron to lead the way.

Ron nodded as he led Harry out of the door (which he had to duck to get through) and lead him to the surprisingly empty common room as Ron yelled, "Hermione!"

"What!?" Hermione's muffled reply was due to her being far way.

"We've got a big problem!" Ron exclaimed. "Meet us in the forest!"

A couple moments later a "fine" was heard and with that, Harry and Ron made their way to the forest.

Not 5 minutes later after Ron and Harry had arrived at where the incident had occurred by the forest Hermione came trudged up to them (Ron specifically), an annoyed look on her face.

"What could be such a big problem to interrupt me when I'm doing my homework?" Hermione asked as she glared at Ron.

"T-that'd be me Hermione." Harry suddenly responded as he let the invisibility cloak slide off of Hermione, causing her eyes to go wide.

"Oh Merlin!" Hermione gasped. "What happened!?"

"You know yesterday, when you cast the growth spell?" Harry asked to which Hermione nodded. "I-I think it hit me by accident."

As Harry said that however, a strange sensation overwhelmed the young pretend as he felt his body begin to shoot up suddenly, stretching his clothes even further as he grew a couple inches in just a short few moments.

"A-and I'm not done." Harry squeaked as he could feel himself growing further, clutching his shoulders as his clothes began to tear at the seams.

When it stopped, Ron and Hermione were now looking up to a 9ft 11inch tall Harry, over double the size of the two, who couldn't look more embarrassed.

"Well let's try this then." Hermione noted. "Shrinkus!"

She pointed her wand as she cast the spell, but unlike with what happened to the book, nothing happened.

"I-it didn't work 'Mione!" Ron stated the obvious.

"We're lucky brought the book with me then." Hermione sighed in relief, going into her bag to find that...

"W-wait, it's not here!" Hermione gasped.

"What do you mean it's not there!?" Harry asked as he looked down to his friends.

"I-I must've left it in my dorm." Hermione answered, a bit panicked. "I never leave behind important stuff though, especially books."

"You must've been in a hurry then." Ron suggested.

"I guess, but-" Hermione was cut off as Harry let out a moan as he found himself growing again, utterly ripping through his clothes as he quickly grew to 14ft tall. His clothes were nothing but a pile of fabric on the floor now and the only part left was his underwear, but even then, it was narrowly holding itself together holding in a large, bulbous mound that was his penis.

Both Hermione and Ron looked away and Harry closed his eyes in embarrassment.

"I've still memorised something about the book though." Hermione exclaimed, giving Harry hope. "There's a mushroom that can reverse the effects and it's found in the forest, but it's pretty rare."

"So, we have to be quick to find it then?" Ron asked.

"Duh." Hermione stated, giving him an exasperated stare.

"Let's find it then!" Harry added as he stared down at them.

"Oh, I don't think so Potter." An oh so familiar voice called out. "I can't let you find a cure now, can I?"

The trio turned around and found a gigantified Draco Malfoy standing there, 2 feet taller than Harry at a whopping 17ft feet tall and, unlike Harry, while his clothes were nowhere to be seen, the boxers he wore fit him perfectly, almost like they were made to stretch as he grew. His body seemed just as toned as Harry's was, if not slightly more and he wore a grin on his face, a confident one.

"M-Malfoy?" Ron stammered in shock as her stared up the giant 10 metres in front of him. "H-HOW!?"

A/n: Hoped you enjoyed part 2! Next part we'll see how Draco grew to be as big as he is, so I hope you'll enjoy it.
