Draco fixed the boys with a mischievous grin.
'Well, well, Potter,' he said, still smiling, 'it seems I have you to thank for this?'
Harry only stood and nodded, his mouth hanging open.
'Ah. Well, thanks, I guess - but you know, I can tell it's your handiwork, Potter. You want to know why? How I can tell that it's your spell, that it's you that I have to thank and not Weasley?'
The Gryffindors continued to stare without saying a word.
'Well, Potter, I'll tell you anyway. It's because, really, of my Auntie Bella - you've met her, haven't you?'
Harry had met Draco's aunt Bellatrix. The first time he had properly seen her, she had killed his uncle. In the aftermath, he had chased her and tried to attack her with the unforgiveable curses - but she had escaped.
'Oh, yes, you've met Bella. Well, she told me what your problem is - how you can't really harm anyone, Potter. You're too sappy for it! You tried cursing her, but you didn't really mean it - you're incapable of being mean, and incapable of making an effort.'
Draco let his words sink in, stretching his nimble fingers, ready his wand.
'So if this -' he gestured at his smooth, amazing, 14ft-tall body with his free hand, ' - if this is what happens when you half-ass a spell ... well, it's got me wondering what would happen if I meant it. If I put some force behind it. If I really wanted it to be big!'
Too late, the bolts in Harry's head slid into place. He snapped out of his stupour and grasped Ron's wrist, yanking him free of the ground as Draco pointed his wand at the large, pale chest -
'ENGORGIO!'
The next few seconds erupted in a blur; Ron's mouth seemed to simultaneously open widen and snap shut, realising with horror what Malfoy had just decided to do. And Harry, hand still locked firmly round Ron's wrist, was caught between watching the spectacle while trying to escape from it. And Draco ...
Draco felt a eurphoria unlike anything he had experienced before. Potter's feeble enlarging charm was nothing compared to his forceful, power-hungry magic, sending waves of ecstacy through every inch of his body.
No longer feeling the need to clench his fists, Malfoy relished the sensation of each inch, centimetre, millimetre of his being expanding with a speed that far surpassed his previous change. The surge of magic immediately jolted him up another 10ft, cracking his head on the ceiling, so that he was forced to squat with his feet planted firmly on the floor; his knees against his ches;, his firm, smooth asscrack poking out of his boxers; his back already grinding uncomfortably against the ceiling.
He raised his eyes to see Potter and Weasley retreating, stumbling through the corridor, being shaken by the tremors caused by Draco's growth. He began to laugh, shaking the corridor further, looking back down to his modest, manly size 12 feet - now over 4ft in length - grinding the flagstones below into chalk. The sight of his fantastically sexy feet spurred him on, and he let out a new wave of bellowing laughter, forcing his back and head up through the stone ceiling as though it were carboard.
'Come on, Potter!' the giant blonde called out, feeling his boxers finally fall apart and his 3ft long cock spring out into the open, growing steadily erect as his voice echoed down hallways and staircases, 'Why bother to run? Why bother to hide from me when I'm this damn big?'
Malfoy shuddered with pleasure as his mammoth body rocketed up past 50ft, bulldozing walls, floors, ceilings, corridors, windows and classrooms as it filled out, griding rubble against his firm asscheeks, his fully erect 6ft cannon-like cock and size 280 feet crushing desks and books and chairs into nothing.
He continued to grow, laughing the whole time at how the mighty stones of Hogwarts crumbled against his growing form like sand. With little effort, Malfoy raised his arms above his head and blasted out through the roof into the open air, rising like a Greek god into a raging conflict.
In the courtyard and the grounds Hogwarts, the students, teachers, ministry officials, memebrs of the order and the followers of Voldemort - even Voldemort himself - all staggered against the severe earthquakes, staring in horror and surprise as a titanic Draco Malfoy emerged from the roof of the school, growing in height and mass until he finally stopped - with his waistline even with the hole in the roof, his20ft cock poking rudely from the side of the building; his long, bony, masculine size 870 feet wriggling through the foundations, his meaty toes pounding against the soft ground.
Malfoy stretched his arms out, arched his back and groaned, as though freshly woken from a deep sleep. Gazing down on the stupefied wizarding community from his height of 150ft, he smacked his lips once or twice, sighed and said:
'Well, this is going to be fun.'
