Summary
     Why is it always Severus who has to clean up the messes made by
     others?
Notes
     This is pretty much 50/50 humour and porn, with some cuteness thrown
     in. Maybe that's why I had so much fun writing it!
 
 
“I cannot believe you would ask this of me! You promised!”
 
“Severus, calm down, please.” Dumbledore looked at him sternly until he finally
sat back down and accepted the teacup. “I apologise for the late hour, but I'm
certain it won't take you all that long.”
 
“Do you not remember the conversation we had when I changed sides?” Severus
demanded.
 
“Yes, but--”
 
“Two conditions, Albus! I had two conditions before I allowed you to use
legilimency on me. And what were they?”
 
“Well--” Dumbledore started, but he was cut off again.
 
“One, never to share my reasons for switching over with anybody. That one
you've kept so far.”
 
“You know I would never--”
 
“And two,” Severus continued with a forbidding expression, “never ever to share
my animangus form with anybody.”
 
“Severus, please. If you would kindly allow me to speak without interruptions?”
 
“Fine. You have one minute.”
 
“Very well. Firstly, you know I would not ask this of you if it weren't an
emergency. However, for some reason, restituo doesn't work. Minerva has been
trying to help, but she can't communicate with him, whoever it is. All we know
that going by age, it must be a sixth year student.” At this point, Severus had
a sinking feeling in his gut, but he pressed his lips shut since Dumbledore
still had twenty-two seconds left. “Secondly, I plan on keeping my promise. I
have not shared anything, nor will I. You may remain unidentified. All I am
asking is for you to transform, and then help the poor boy join the humanity.”
 
“If I recall, there is a certain sixth year student whose father was an
unregistered animangus.”
 
“Now, now, you mustn't go blaming Harry without proof,” Dumbledore admonished.
“We haven't checked any of the dorms. For all we know, it could be any one of
the sixth years. Or any one of the boys at least.”
 
He so didn't want to know how they had come to know that detail. Instead, he
asked wryly, “Care for a bet about the culprit?”
 
“Ah, would you look at the time,” Albus said quickly. “Must be off to bed. Can
I trust you to take care of this, preferably before breakfast?”
 
“As you wish.”
 
“Oh, and we put him in the Prefects' bath,” the headmaster twinkled, “with a
few hundred ice cubes.”
 
“Perfect.”

Severus scowled as he stood in the pile of robes. Or tried to scowl, but of
course the expression wouldn't happen now. Changing into his animangus form was
something he hardly ever did, for it caused uncomfortable flashbacks. He'd
never forget the disappointment of his teenage self when he'd finally succeeded
in the transformation after months of practice, only to find that he had become
a penguin.
 
A penguin.
 
The pure embarrassment. Of all the things he'd imagined – searching the skies
as an eagle, wind in his wings; running as a panther, fast and unstoppable;
discovering the secrets of Hogwarts as a snake – and this was what he got. It
was typical of his life. Penguins were altogether pointless animals. No flying,
no running, no stealth, just splashing around in water. But worse than that –
penguins were cute.
 
Severus still shuddered at the thought.
 
Right, best to get this over with as quickly and efficiently as possible. He'd
made sure to crack the door open before changing, and now he squeezed through,
dragging the clothes with him. He was satisfied to learn that his silent and
wandless warding spell still worked as a penguin. The last thing he needed was
Mrs. Norris hearing sounds from the bathroom and bringing Filch to investigate.
 
Avoiding any mirrors, Severus waddled his way to the bathtub, jumped onto the
ledge, and peered into the large bathtub.
 
He smirked, as much as the beak allowed him to. Potter was an Eudyptula minor.
Little Penguin. How appropriate that even his animangus form would be a midget.
 
After being momentarily distracted by wondering whether the alternative name,
Fairy Penguin, was also fitting, Severus focused his attention back on the tiny
bird. It was diving and jumping up in the bathtub, oblivious to his presence.
At least Severus could now feel slightly better about his own form, Pygoscelis
adeliae . Adélie Penguins may have been ridiculously small compared to the
Emperors, but at least he was five times bigger than Potter was. And a sleek
black and white colour, not some shabby blue.
 
Severus dove into the water gracefully. At least the boy had possessed the
sense to turn up the heating enough to melt the ice Albus had supplied. Based
on Severus' limited experience, penguins' fondness for cold was a complete myth
– he much preferred hot water baths, regardless of his shape.
 
Severus swam around for a little while, taking guilty pleasure in the way his
body melded with the water. Finally, though, he was forced to acknowledge the
other penguin, who was flapping around and staring at him.
 
“Potter.”
 
“Yeah,” the penguin confirmed. “Please tell me you're not an actual penguin.”
 
“Where do you think the headmaster would have acquired a penguin at this time
of night, and what possible use would that have been?”
 
“Wow, I didn't know that penguins could roll their eyes!” Potter squealed. “So,
who are you?”
 
“Never mind that. I am merely here because Professor Dumbledore insisted I help
you.”
 
“Thank fuck for that, I was starting to worry. Not that being a penguin isn't
great, but I'd miss flying. And eating. Don't much like fish, you know? And I
don't even know if penguins can wank--”
 
“Potter.”
 
“--let alone have sex, except maybe with other penguins--”
 
“Potter,” Severus repeated, slightly alarmed by the penguin's speculative look.
 
“--that might be interesting, I guess, but I think I'd rather have my first
time as a human, don't even know if penguin sex would need lube and how we'd
use it without--”
 
“Potter!” Severus snapped. “For Salazar's sake, be quiet. Now, animangus
transformation should never be attempted unsupervised, which you would know, if
you weren't such a brash Gryffindor.” Severus saw no reason to mention his own
solitary ventures. He may have ended up a penguin, but at least he'd not been
stupid enough to get himself stuck as one. “Of all the imbecilic, reckless,
asinine--”
 
“Snape?!”
 
“How many times do you have to be told to address your professors as--” Severus
started, then stopped short. “Wait, how did you know it was me?”
 
“Oh,” the other penguin said, looking shifty, if such a thing was possible for
a bird. “Just a lucky guess.”
 
“Perfect,” Severus said. Potter and his damned luck. “Now that our identities
have been established, why don't we get this over with. Change back, if you
please.”
 
“In case you haven't noticed, I can't.”
 
“You are perfectly able to. You must simply apply yourself.”
 
“Um, yeah,” the other penguin said when nothing had happened in five long
minutes, “I'm gonna need something a bit more detailed.”
 
“Oh, for pity's sake, Potter. You just visualise your usual body. Short and
slim, messy black hair, green eyes, red lips, subtle muscles on your arms and
legs and--” Severus suddenly cut himself off when he noticed the other penguin
staring at him with its head tilted to the side. “Well. You get the picture.”
 
“Okay.” Potter the penguin swayed calmly along the water for a while, then
plunged in with a great splash, coming up and squeaking, “I can't!”
 
Severus sighed mentally, as penguins weren't well equipped for such a sound.
“It is not difficult. Close your eyes, like this. Then just think. It's
probably a foreign concept to you, but try. Imagine yourself as human.” There
was silence during which Severus held his eyes closed and allowed his mind to
wander.
 
“Well, fuck,” Severus said, when suddenly he found himself sitting neck-deep in
water, in a very human body and with a very human Harry Potter on his lap. Very
naked and human Harry Potter. Sitting on his very naked self. And, more
specifically, a part of himself that was rapidly taking interest in that fact.
“Fuck,” Severus repeated smartly.
 
Potter's eyes were round and startled, and so, so green. Severus decided that
the boy blushed gorgeously. Even better, though, was that Severus' prick
clearly wasn't the only one interested in the proceedings.
 
“Fuck,” Potter agreed when Severus ran his hands along the muscles on his arse,
and then the boy cursed again as Severus' hips jerked and their cocks rubbed
together.
 
Severus decided that since any communication with human Potter was apparently
even worse than it had been with the penguin, their mouths could be put to
better use. This soon proved to be an excellent idea, for the boy's mouth
tasted exhilarating. The supple body writhed maddeningly, and Severus pulled it
closer, easily circling his arm around Potter's narrow waist. With his other
hand he discovered that grasping the mess of hair was practical while tasting
the smooth skin of Potter's chin and throat.
 
“Ahh, god, Snape,” Potter moaned as Severus sucked a mark above his clavicle.
“Wait... you don't want me to address you as professor now, do you?”
 
“Of course not,” Severus said. “Sir will do.”
 
“Yes, sir,” Potter said. The way Severus' cock responded made him question what
he'd gotten himself into. Or, more accurately, what he was about to get himself
into.
 
“I do not know about penguins, nor have I any wish to, but as humans we shall
definitely need lubrication for this,” Severus said. “Get up and turn around.”
For once Potter did as he was told, Severus noted with satisfaction. “Now lean
over the edge, over here where the water is shallower.”
 
“What are you-- oh!”
 
“I am demonstrating the usefulness of wandless spells first hand. So to speak.”
Severus pressed his index finger on Potter's anus. “Lubrico.”
 
“Ahh,” Potter moaned as the finger slid in with only a slight resistance.
Severus felt like moaning as well, imagining the same tightness surrounding his
cock. However, he took the time to give Potter's virgin arse all the worship it
deserved, stretching him slowly and carefully until the boy was humping the
tile, his whole body practically begging for more.
 
“Something you would like?” Severus twisted his fingers to reach the prostate,
reducing Potter to incoherent moans. “Hmm? I didn't quite catch that.”
 
“Ahhh, fuck--”, the boy panted, “you, sir. Fuck me, make me come. Please!”
 
Who was Severus to resist such a request?
 
Merlin's lacy knickers, the boy was tight, tight and perfect. The noises he
made when Severus' cock breached him were nearly too delicious. As soon as he
was fully sheathed, Severus grasped Potter's hair and claimed his mouth while
he waited for his prick's throbbing to ease. It hardly helped, though. The
boy's inexperienced kisses tasted of innocence that only made Severus more
aroused.
 
Most of his lovers he'd ended up bedding by following either only his mind,
where more powerful wizards were concerned, or only his body, when he resorted
to Knockturn rentboys. But with Potter, Severus' mind and body were for once
united in desire, wanting to defile him and claim him, to make the boy
tarnished and dirty and his.
 
He didn't let up Potter's mouth as he started rocking into him, swallowing the
wanton sounds until his need for air became too strong to resist. Potter looked
delectable, his mouth kissed raw, his neck arched by Severus' strong grasp.
Severus bit on the purple mark on the boy's shoulder, making him cry out.
 
“Good.” Severus let go of Potter's hip to circle his erection. It only took a
few strokes before Potter was spilling his seed, the tight arse contracting
around Severus' cock. He cursed, driving in harder, clutching Potter's shoulder
as he rammed into him, fucking him against the tiled ledge. And then the
pleasure was sweeping him with it, making a growl escape his throat as his cock
pulsed, filling Potter's arse with his come. He pulled out and groaned aloud as
rest of his spunk coated the boy's smooth arsecheeks.
 
“Such a dirty boy,” Severus murmured. Potter answered with a gasp as Severus
rubbed his fingers across his used hole. “You should get cleaned up.”
 
“Yes, sir,” Potter said breathlessly, before pushing himself off the ledge and
back into the water.
 
Severus reached for soap, but stopped startled when something soft swam from
between his legs. “Very bloody amusing,” he groused.
 
“Squeak!” the penguin replied.
 
“One of these days I shall demand a pay rise.” Severus washed himself, not even
glancing at the persistent bird, which seemed to have decided that it would not
be ignored.
 
As a tactic, neither splashing Severus nor nudging his legs was working.
However, when Severus started to wash his privates, the stupid thing surfaced
and stared. The effect was likely unintentional – Potter and his damned luck –
but that proved a better strategy. The knowledge that it was Potter watching
him was threatening to have stirring effects on his parts, despite the recent
relief. And while not many things could freak out Severus Snape, having a
penguin ogling him most definitely fell into that category.
 
Finally, he resigned to his fate and transformed. “What do you want now?”
 
“I thought I'd be quicker to wash like this,” Potter said, “plus, you're really
cute as a penguin.”
 
“Perfect.” He'd never live this down. He hated that the stupid animangus form
couldn't scowl menacingly. Potter didn't seem nearly as scared of him as
students usually were. On the other hand, Potter was rarely scared of him even
when Severus wasn't a penguin.
 
“We are done here,” he stated. “Now change back.”
 
“Er--”
 
“Potter.”
 
“It's just, I don't really remember how to. So I'm kind of stuck.”
 
“Again.”
 
“I was a bit distracted last time,” Potter said. Severus conceded the point.
 
“Perhaps it is simply a better motivation you require,” he said. “I don't
suppose you have discovered penguin masturbation techniques.”
 
“Well, we could try--”
 
“No.”
 
“Fine.” Potter the penguin closed his eyes, and soon resumed his human form.
 
Severus followed suit and climbed out of the bath after Potter, who was drying
himself in a muggle way. However, the boy was looking no worse for wear,
neither for having spent eight hours as a penguin nor for having had Severus'
cock in him, so he considered his duty to Dumbledore fulfilled.
 
“I think I need more practice with animangus transformation,” Potter mused.
 
“Among other things,” Severus said, pulling on his robes after he'd spelled
himself dry.
 
“Will you supervise me?”
 
“Among other things.” Severus stepped closer to the boy and licked a stripe up
his neck to his ear. “Just as long as we are clear that I shall not be having
penguin sex with you.”
 
“Mm-hm,” Potter grinned. “That's what you say now.”
