Rule Number 379

Hogwart's rule number 379: I cannot lock the Slytherin's and Gryffindor's in a room together and take bets on which house will come out alive.

Harry had no idea how he got himself into this mess.
'Two Galleons a bet!'
'Slytherin versus Gryffindor!'
Harry sighed, watching the shadows of students dance on the darkened classroom windows.
'Can I bet on both sides?'
The boy legend plonked himself into a chair.
'What are you nuts?'
'That's ridiculous!'
Potter looked over the desks at his blond rival examining his cuticles.
'Well, there is a chance that they could knock each other out…'
'… Slytherin versus Gryffindor –!'
' – or a dead tie!'
'Two Galleons a bet!'
'Oi, you two seen Harry?'
Harry sighed again, chin in the heel of his palm.
'What's it to you?'
'He is my best mate!'
'Five Galleons on Slytherin.'
'… what are you two doing? The Quidditch match was a few days ago.'
Malfoy glared at Potter, remembering the match and Harry smirks.
'How savage!'
'Just a bit of fun and money-making –'
' – it's not against the rules to bet!'
'Hmmph!'
'How long's the bet running for?'
'When one of them comes out these doors –'
' – or until a teacher finds out!'
The lion pushed out of the chair and approached the snake.
'Malfoy –'
' – Buss off, Potter!' he turned his back away, 'I'm not playing any games, or joining this stupid duel!'
Harry rolled his eyes, 'I don't want to duel, I want to –'
' – None of that either!' Draco huffed, jumping off the desk and away from the Boy-Who-Lived.
'I'm going to tell, Professor McGonagall!'
'Spoil-sport!'
Harry threw a silencing charm over the room, 'Look – we have no real interest in each other, so I don't understand why you've got your pants in a twist.'
'My pants are perfectly fine!' growled the blond.
'Then what's your problem?' Harry whirled the smaller boy around, 'You haven't even been keeping up with the usual snide remarks!'
The Slytherin blushed, 'I would – it's just –' he groaned, rolling his eyes, 'I go to make fun of you and your pathetic group and I – I get a raging boner, okay?'
The lion burst out laughing.
'Oh, shut up, Potter!' Draco hit him.
'I'm sorry,' giggles the golden boy, 'I didn't think I left that much for you to think on.'
'Don't think you're all that!' Malfoy shoved a finger in Potter's face, 'It's not you, just what you did, and that's all!'
Harry continued laughing.
'Stop it!' shrieked the blond, stamping a foot.
'It can't be as bad as you're making it out to be,' smirked Harry.
And then the Slytherin dropped his trousers, and there at full mast, was the snake's glory.
'This is your fault!' he screamed and the Gryffindor laughed again, 'And I demand you fix it!'
'What?' Harry smirked, 'You can't make me do anything, besides what would be in it for me?'
The blond cleared his throat, 'I'll let you… y'know…'
The raven smirked, 'Really?' and Draco nodded, 'Well, turn around then!'
Malfoy sighed, turned and leant his elbows on the desk.
SMACK!
Malfoy winced, a red hand appeared on his bare bottom, and it jiggled slightly from the impact.
The Slytherin was about to stand back up until he felt a kiss placed on his raw backside, and a hand run up and down his inner thigh.
The Gryffindor pulled away, taking the discarded trousers with him, 'Sit,' he commanded and the snake obliged.
'Nothing intimate,' said Malfoy and Potter kissed his knee.
'Of course – this means nothing,' he said, trailing his lips up Draco's leg.
The Pure-Blood lent back on the heels of his palms as Harry climbed higher up his thighs.
'But –' Malfoy let out an irritated groan.
'What?'
'You have to say it again,' and there was a sigh.
'No,' fingers ghosted circles.
'Please,' begged Potter, and Malfoy glared down into his eyes, and his prick twitched.
'… just do it… Harry.'
And the Slytherin's head was engulfed. A moan vibrated through Malfoy's throat as Potter's tongue glided over his penis, touching everything, but not enough of him.
Harry hummed a strange tune, as if this were an ordinary activity, like washing the dishes, his fingers skilfully caressing the blonde's balls.
Draco gripped the desk, knuckles turning white, jaw slack and happily moaned.
The golden boy's teeth ran over Malfoy's head, bumping over every dip and vein; his tongue hungrily slurping at the Slytherin's dick.
Harry bobbed his head casually and Draco squirmed, 'Faster,' he demanded, breath getting caught between moans.
And so he accelerated, pushing more and more down his throat, Malfoy panting harder, 'Merlin -!'
The lion squeezed his cheeks in, sucking more, dribbling pre-cum down his chin. The snake's fingers clenched and released on the edge of the desk, his toes curling as the heat built up.
'Harry –' he warned, but the aforementioned boy gained more speed, and then the snake burst like a full dam.
His sperm pumped out of him as he shivered out his climax, and Harry lapped it up, like a kitten drinking milk; still humming as if it were nothing.
Draco laid back on the desk, his penis slowly deflating.
The Boy-Who-Lived cleaned himself up, and replaced the Pure-blood's trousers.
'See ya, Malfoy,' he smirked, releasing the silencing charm and opening the door.
'Looks like Gryffindor wins!'
'Uh-uh, Zabini, I remember you voted for Slytherin – Pay up!'
