****** Detention, Mr. Potter! ******
by LadyPurity
Summary
     Harry has mixed feelings about his detention. Professor Snape will
     have to do something about that.

“Potter!”
Harry tensed, lifting his face warily.
“What is… that?” Snape sneered into Harry’s cauldron.
“Clearly not a calming draught,” Harry sighed.
Snape’s eyes narrowed as he vanished forty-five minutes worth of useless
attempt at a potion. “Detention, Mr. Potter,” he all but growled.
                                 o 0 o O o 0 o
Harry entered the potions lab with a damnable combination of dread and
excitement.
Predictably, the door slammed and locked behind him. He approached his
professor’s desk to find the man leaning against it with a tiny smirk on his
thin lips. When Harry just stood there, Snape’s brow rose and Harry sighed
heavily as he began removing his clothes, folding them carefully and piling
them on a table. When he was completely naked, he turned to face his professor
again.
Snape’s smirk grew as those black eyes examined the boy before him. “Excited,
Potter?” he drawled.
Harry knew that his whole face was turning red enough to rival Ron best blush,
but he kept his chin high while his professor stared at his cock, which was
only growing harder under the scrutiny.
A small nod of the professor’s head sent Harry around the man’s desk, where he
leaned down to rest the side of his face on a pile of parchment, probably
student essays. With trembling hands, he reached behind him and spread his
cheeks.
He could hear Snape move around behind him and he squeezed his eyes shut,
dreading and longing for what he knew would come next. What always came next.
He squirmed and squeaked when the fingers were shoved into him, completely dry
and not at all gently. A third joined the first two almost immediately and it
was all that Harry could do to keep from screaming. It hurt. Merlin it hurt. He
shouldn’t have enjoyed it.
But he did.
The fingers started to move faster, stretching him painfully, burning with each
dry slide through his tender flesh.
When they finally stopped, he gasped for breath, whimpering quietly and wanting
nothing more than to reach around and wank. He kept his hands where they were
though. He’d learned the hard way that he wasn’t allowed to touch himself in
any way not explicitly instructed by his professor. Honestly, if Snape had made
a fraction of this much effort to teach him potions, Harry was sure he’d be
well on his way to his potions’ mastery by now.
A warm tongue soothed the tormented hole and Harry released a low, drawn-out
moan of pleasure. Dear Gods, Snape had never done that before. He’d always
caused Harry more pain that pleasure until he was satisfied, then sent Harry
off to wank in his bed before he’d have any hope of getting to sleep. He heard
a small, low chuckle, and then the tongue again. Harry whimpered in pure
pleasure this time, and fought the urge to rock against the sinfully wonderful
tongue.
He almost cried when he felt Snape move away, but then the familiar pressure of
a large cock head nuzzled against his hole and a desperate whine escaped him.
He was so fucking hot!
“Do you want this, Potter?” the professor’s low voice asked mockingly.
“Yes, sir,” Harry gasped. He didn’t expect Snape to stop at this point, but he
wasn’t taking any chances. He wanted it very badly.
“You want my cock in your ass?”
“Oh… Gods, yes! Please, Professor!”
He had evidently said the magic word, because he’d no sooner stopped talking
than Snape was inside him. His shamefully high-pitched cries echoed off the
dungeons walls as his teacher plunged into him repeatedly, hard and fast and
absolutely fucking perfect!
The pain seemed to grow with every thrust, and Snape’s stamina was not lacking
despite his rapid tempo. Tears streamed freely from Harry’s eyes in a very
short time, most likely ruining the essay beneath his face and staining him
with ink. He didn’t care.
Sometime after his voice had grown hoarse and he was certain that it was blood
now providing a bit of lubrication against Snape’s cock, a hand fisted in
Harry’s hair and he was wrenched fully upright, his back flush against a hot
chest.
A few more thrusts, and Snape’s teeth scraped against his ear while a large
hand closed around his cock.
Harry cried out incoherently as his balls tightened, and he exploded in a rush
of blinding pleasure, his sticky white seed shooting all over Snape’s desk and
the essays now scattered there. Some part of him recognized Hermione’s
handwriting on the top paper and the fact that he knew he’d think of this every
time he saw her for a week made it even fucking hotter.
Snape groaned in his ear and Harry moaned a reply as he felt his professor’s
hot come fill him.
For a long moment, they just stood there, Harry in his teacher’s arms, his cock
in Harry’s ass. Then, with a languid sigh, Snape pulled himself free and flung
his naked body down in the chair behind his desk. “Get dressed,” he said
breathily. “There are still cauldrons to scrub.”
                                 o 0 o O o 0 o
“Potter, that is the worst excuse for a restorative elixir that I have ever
seen!” Snape sneered, vanishing the potion. “Ten points from Gryffindor, and
zero marks for today, Mr. Potter.”
Harry frowned when the professor started to talk away. “That’s not fair!” he
called after him, just as indignantly as he could manage.
Snape spun back on him, eyes blazing. “Detention, Mr. Potter! For a week!”
Harry felt his lips try to twitch toward a smile and forced them to stop before
anyone noticed.
Snape’s eyes fell very briefly toward his lips and Harry could have sworn he
saw a smirk before the professor turned away again.
