Unexpected 6, by Seeker. Rated NC17.

<><><><><><><><><><>

Remus Lupin'd had his paws, er, hands full since the final battle against the Death Eaters of Voldemort (or as he liked to call them, those Pain-in-the-arse Losers with the Collective Death Wish). With the Dark Lord's normal timing, crappy for his side and perfect for his enemies, he'd called for the Apocalypse during a full moon, which played right into Remus' plans. As the Commander in Chief of the Combined Monsters Corps, leading mixed companies of werewolves, hippogriffs, and renegade mountain trolls against the Losers, Remus struck a blow for monsters everywhere, as many of the nastiest Death Eaters also turned out to be many of the tastiest.

On a personally triumphant note, as CiC-CMC, after the battle he was offered a position at Hogwarts as Master of Care of Magical Creatures. It was a task much more to his taste than his previous DADA position. Flush from victory, and with vivid memories of werewolves eating Death Eaters in precision formation, none of the surviving parents made a single protest.

Next step, legal rights for carnivores, an end to segregation of magical groups and the legalization of wolfsbane. Maybe even a push to fund Ministry of Magic trials to discover a way to make the shit palatable. Since the majority of the Ministry had either fled forever or been torched by Voldemort, and the new Head of Internal Affairs just happened to be one of Remus' werewolf buddies out of the Lake District, he had high hopes.

Then there was Sirius. Rehabilitation of Azkaban had included the destruction of the few remaining Dementors who hadn't already been assimilated by the Death Eaters, and with the help of the few remaining sane Aurors, several falsely imprisoned wizards had been cleared of all charges and let loose, his old friend Sirius among them. Of course, several free wizards had been found to be disguised Death Eaters, and they were fed to the mountain trolls, making everyone (except the Losers) quite happy. Lucius Malfoy, in particular, had been deemed "Luscious!" as he was going down. His whining little cub was still screaming about that, but not too loudly, lest he be dessert.

Still, a few whinging brats aside, it was a glorious time to be a werewolf and an even better time to be a werewolf named Remus Lupin. Life was grand, he was getting paid regularly with a roof over his head and new robes on his back, Sirius was ensconced in his bed when not helping McGonagall in the classroom, and their godson Harry was doing a bang-up job as DADA Master. There was one odd little tidbit that nagged at Remus' attention, though.

Severus Snape. He'd been cleared of duplicity with the Losers, since he was spying for the Winners most of the time. He'd fought well and bravely, and even suffered the permanent effect of a curse in service to the Light (or Harry Potter, but really, the two were synonymous). In the course of saving Harry from an age-reversal spell that would have taken him back before he was born, effectively killing him, Snape took the full brunt of the spell. Rapid age regression hurt like hell, nearly killed him, in fact, but the final results ... were stunning.

And if Remus' nose was anything to go by ... and it always was ... the DADA Master wasn't the only thing Harry was doing a bang-up job at. Snape looked dead sexy as a twenty-something, and he smelled like he was getting fucked on a *very* regular basis. He took to his rooms unexpectedly, staying there a day or more at a time, and when he appeared in public he was either being chased by his students or ogled by his fellow faculty. More often than not, he walked like he'd been ridden into the floor the night before. There'd even been rumors of Harry ambushing Snape in class. In the forest. In the halls. Everywhere he could find a shadow dark enough to hide them both and not frighten the children.

Although from the way the children followed the pair of them, tongues hanging out, they'd probably have a paying audience before they had a frightened one.

All in all, it was enough to drive Remus mad. His curiosity was piqued to the point of no return when Snape came to afternoon tea one day smelling of Harry, semen, sweat, dirt, dungeon dust, grass, and most intriguingly, Hagrid. So, armed with the excuse that he needed a sleeping draught for the griffin he was introducing to his fifth years the next week, that night after dinner Remus swept silently down the dungeon steps and made his way to Snape's chambers.

There was no one there.

Nor was there anyone in Snape's classroom. His workroom, his storeroom, the little room with the cot in it where he took naps between classes when his students gave him the headache, the bathroom, the toilet, or the teachers' retiring room. Remus then tried Harry's rooms, his classroom, the Quidditch pitch, under the bleachers, below the announcer's box, the broom room (informally known as The Seeker's Sex Space), and most of the No Longer Forbidden Forest. By the time he gave up it was dawn.

As he dragged himself back into Hogwarts he saw Harry hauling an exhausted-looking Snape down from Trelawney's old rooms. They'd been abandoned since the old bat failed to foresee Death coming down on her in the form of an explosive curse from one of the Losers. Harry was muttering something about 'best damned time I ever had in that hellhole' while Snape sleep-walked, from the look of him.

Shrugging philosophically, being nothing if not patient, Remus fell back and waited for a better opportunity. It came a few days later, after things came to a head on the student-assault front. Albus stood at the faculty table and addressed the assembled students, most of whom were so busy eating (those who hadn't hit puberty yet) or visibly lusting after Harry and Snape (everyone else including ghosts, assorted magical creatures and quite a few inanimate objects).

"It's come to my attention that there is a slight problem with discipline," Dumbledore began.

Several students either moaned or made enthusiastic suggestions for whips and bare bottoms. McGonagall glared fiercely around the hall, and Albus frowned vaguely. Most of the faculty drifted off into private fantasies. Remus glanced over at the lovebirds. Harry was looking at Snape with a measuring eye, and Snape looked grumpy, terrified, and aroused. Since his age regression and his new relationship, Snape's range of expression had expanded considerably beyond his standard rotation of 'pissy' or 'intimidating' stares.

Albus cleared his throat, then did it a second time, loudly enough to rattle the dishes. That finally shut off the stream of suggestions, rapidly becoming quite obscene. "This is a school, not a boudoir!"

"Bordello," murmured McGonagall. Dumbledore swept on.

"Students will act with the utmost respect toward their professors or they will be disciplined!" A yearning sigh swept all the students over the age of consent. "With a castration spell that will only be reversed upon graduation!"

The sigh strangled into a concerted gasp of dismay as, in unison, several hundred pairs of legs crossed instinctively in a genital-defensive position. Before the girls could take up the lusty cry, Dumbledore snapped, "And for those for whom such a spell is ineffective, there are always chastity belts! With teeth!"

The rest of the legs in the hall crossed and the dismayed gasp now spanned all octaves.

With a benevolent smile, Albus raised his glass, "And so, with that little problem solved, let's sing the Hogwarts Song and get this term off to a fresh start!"

The Song was a trifle higher-pitched and a tad more strained than usual.

Remus waited and watched. Dumbledore's proclamation hadn't mentioned other faculty, and given that he'd been canoodling Minerva for several decades, Remus knew he was safe stalking Snape and Harry. So late that night, when all the world but lovers and creatures of the night were asleep, he followed his nose up the tower on the trail of Harry and the surprisingly-sexy Snape.

He had an excuse, in the griffin-potion; he had a cheat-sheet of passwords Sirius had lifted for him from Minerva's office upon promise of recitation of all the details; he had his usual werewolf stealth-tread. He needed none of them. At the entryway to Harry's tower suite, the dame in the portrait who should have challenged him for the password sat in the corner of the frame, peering through the crack of the opened door, paying all her attention to what was happening inside the room and none to any possible intruders. From the way her hand was moving her petticoats Remus had no trouble understanding her preoccupation, and he took full advantage of it to slip past her into the room. She didn't so much as squeak.

Well, not about passwords anyway.

Once in, he crept silently into the bedroom, barely seen from the doorway. She must've had good eyesight. Not that anyone heard him. The inhabitants were too engrossed in one another to heed his entry, or demand his ready excuse. Remus was happy for that preoccupation, given his moaned, "bloody hell!" at the sight that met his eyes, and the not-exactly-stealthy way he had to grab his balls to keep from coming before the party had barely begun.

The bed sat three-quarters to the door, giving the audience of one a perfect view of the festivities. Snape lay on his belly, crotch propped up on pillows, arms manacled above his head to a hook in the wall, although there was plenty of play in the chains, as he had his head resting on his forearms. There was less play at the other end, as his feet were spread and his ankles were chained to the end-posts of the bed. The position showed off his lean body to perfection, the muscles outlined clearly in the long arms and legs, the lovely curve of the buttocks, the arch of the spine, all quivering beneath flushed skin streaked with sweat and scratch marks.

Remus licked his lips before the drool spilled down over his chin. He refrained from either growling or howling. Barely.

Between those long, shaking, bound legs young Harry, all grown up and quite a grown-up he'd become, rutted away enthusiastically in the offered arse. His legs were slightly longer than Snape's, and he used the added inch to advantage, putting his back in his thrusts and lifting Snape clear off the bed with each push. Remus inched closer, angling toward the foot of the bed. From the new angle, he could see Snape's prick and balls, bound in what looked like a leather cage, purpling and swelling, pressed at a downward angle on the backside of the pillow. Every time Harry came down on Snape's arse, the prick got crushed into the caged balls, and every time he drew back, the prick got dragged along the edge of the pillow.

It must have hurt like a bitch. And from the way Snape was urging Harry on, he must have been loving every second of it. The reek of musk and sex coming off the pair nearly knocked Remus off his feet.

So, Snape was kinky. No surprise there. So, so was Harry. Remus flashed on long-ago memories of himself in the middle of a sweaty knot, Sirius pumping away behind while James sucked enthusiastically from the front, hands squeezing everywhere. So, no surprise there, either. He got it from his Da. Remus was just settling in for a nice long show and a little handy wrist action when Harry nearly startled him into wolf-form.

"Why are you clear over there, Remus?" he panted, rotating his hips in a way that flexed his arse cheeks beautifully and made Snape scream. Or maybe the scream was shock at Remus' presence, it was impossible to tell, since Snape wasn't forming words, just making random noises. "Come join the party."

Remus was naked and bouncing on the bed almost before Harry got the words out. Snape glared at him, one dark eye burning through sweat-wet hair, but before he could say anything, Harry thrust all the way in, stayed there, grabbed the hair on Snape's head and yanked his head back. Remus panted.

"This is what you want, isn't it, my bitch?" Harry purred. Snape whimpered. "Louder, Severus," Harry commanded him gently.

"Yes!" screamed Snape.

Well, that was plain enough. Harry loosened his grip, then pulled out completely, bent over Snape's shoulder, and kissed him with unmistakable ownership. Remus' pant got a little growl in it.

"Good bitch," Harry whispered. Goosebumps rose all over Snape's body. "But you've been ridden for awhile, and I know how hot you are when you're tight." The goosebumps doubled, but Snape didn't say anything. "Remus," Harry drew his attention and Remus tore his eyes away from Snape to toss him a questioning look. "Go up to the head of the bed and feed him your prick."

Again, Remus was there practically before Harry finished speaking. "He doesn't bite, does he?" No joke there. Snape's eyes were open and glaring up at him again.

"If he does, we stop touching him and leave him like this. Then we call Peeves in."

The glare instantly mutated into a plea. Remus grinned. Snape's mouth opened. Remus stuck his prick in. As soon as he did, Snape started licking and sucking at it like a ravenous dog on a juicy bone. The growl that had been threatening broke through. Snape's sucking got even hungrier at the sound.

"God, that's sexy," Harry breathed. Remus forced his gaze away from the way Snape's lips stretched around his erection and the bulge it made pushing against his cheek to see Harry pulling a butt plug from a box next to the bed. It was at least five inches long, and close to three inches around in the middle, with little bumps and ridges all over it. "One of Severus' favorite little toys."

"Little?" Remus choked out. The sucking at his cock could only be described as frenzied as Harry gave a truly wicked grin and shoved the plug up Snape's arse, the force needed to pop it in making muscles stand out all along his arm and shoulder. Snape's tongue fluttered along Remus' shaft as he screamed, and the vibration nearly made him come. Reaching down, Remus gave his own balls a nasty twist, yelping with pain and relief when he softened just enough to keep from exploding. "Now what?" he panted, one hand twisting helplessly in Snape's hair as his hips began to move and he fucked Snape's throat.

"Now we tighten him up for you!" Harry informed him cheerfully, pulling out an evil-looking paddle from the same box. "Another of Severus' favorites. Oh, and Remus, make sure you pull out once in awhile and let him breathe. It'd be a shame to have to wait for him to come to before you fuck him."

Oh. Right. Remus eased out and Snape gasped air through his nose. Wait. Remus looked down at the watering eyes, distended mouth, and thoroughly excited expression on Snape's face and said, dumbly, "Fuck?"

"Sure," Harry answered, raising the paddle high. "Why d'you think I'm tightening him up for you?" Then he brought the paddle down full strength, directly across both arse cheeks, the middle of the paddle striking the finger-grip at the center of the plug, shaking it in Snape's arse at the same time that the muscles in his arse tightened from the blow.

If the first scream had nearly made him cream, the prolonged howl that move brought forth nearly took the top of Remus' head off, given that it was timed perfectly to land just as he thrust the length of his prick back down Snape's throat. His hand shot to his balls and he twisted again, hissing and yelping and pumping his hips. Harry matched his rhythm perfectly; as Remus drew out, Snape dragged in air, and as Remus pumped back in, Harry smacked Snape's arse, knocking all that lovely air right back out of him in the form of another spine-melting, prick-milking scream.

Remus would have been quite happy to continue in this vein for the rest of his natural life, or until the next full moon, given that if he wolfed-out in his current position he might instinctively eat Snape, and where would the fun be in that? But Harry had other plans. Snape was nearly delirious from oxygen-starvation, endorphins, agony and ecstasy in his arse, prick and balls to have any input, and Remus was along for the ride, so Harry did what he wanted and the others followed along happily.

Dropping the paddle carefully back in the box, muttering a cleaning spell as he did, Harry leaned down and bit Snape's arse cheeks, right then left, dead center, adding bite bruises to the welts from the paddle. Snape moaned around Remus' prick and Remus moaned along with him. Rubbing the stinging flesh firmly, Harry grinned up at Remus. "Ready?" he asked, leaning back up and hooking two fingers in the handle of the plug. "Pull out!" he ordered, and Remus did, at the exact same time that Harry yanked the plug out of Snape's arse.

The long, wavering howl Snape gave sounded almost as good as would have felt. Remus licked dry lips and glanced over at Harry, who motioned for him to move. Climbing carefully over Snape, dragging the dripping, sticky end of his prick over Snape's face, through his hair, over his shoulder and down his back as he did, Remus positioned himself on his knees between Snape's thighs. Then he looked over at Harry for his permission.

"On your knees, darling Severus," Harry commanded gently, and Snape automatically shifted backward until his arse was held high, his arms now stretched above his head, his steadily-leaking prick in its bindings waving in the air above the pillow. "Now, Remus," Harry said, reaching under to remove the pillow, "fuck him hard."

He didn't need to be told twice. Wrapping his hands around Snape's hips, Remus lined up his aching prick and shoved it all the way in with one hard thrust. Snape's head, hanging down between his biceps, reared up and he screamed again, but he didn't squirm away. Quite the contrary; he bore back, as if his arse was starving for Remus' prick, meeting the thrust with all the strength in his shivering body. The muscular curves of his arse cheeks were fire-hot against Remus' groin and upper thighs, the hole clenching around his prick felt like a moving iron band, fluttering convulsively, closed, relaxed, closed tighter still as Remus moved. Snape and Remus were both moaning and growling, panting as they rutted, Snape clawing at the sheets beneath his hands, Remus clawing at the hips beneath his own.

Harry watched with a greedy expression on his face, eyes shining, mouth open, muttering encouragement to Snape and Remus equally. One hand traced below Snape, and bending his head to glance under, Remus could see Harry pinching Snape's nipples, twisting and pulling them, then roaming down to pull at head of Snape's prick, as if trying to yank the trapped foreskin back over the swollen purple head with his fingernails. Snape shuddered with each pin-prick caress, bucking and squirming against Remus. Then Harry moved his other hand back behind Remus, his fingers heading unerringly for Remus' own arsehole.

Remus gave him a startled look, and Harry cocked his head in a question. "Fuck, yes," Remus groaned, then stilled as Harry carefully settled himself behind Remus, his knees pushing Remus's apart, thus forcing Snape's thighs even wider, until he was almost lying on his belly, only Remus' hands on his hips and prick up his arse keeping him in place. His bound prick bounced a bare inch from the surface of the bed, and he was sobbing for relief by this point. The hot bundle of flesh felt delicious against Remus' own balls when it hit them, and Snape's prick left a trail of pre-come all over the sheets. Despite his pleas, or perhaps because of them, neither Harry nor Remus would allow completion quite yet.

Working his way into Remus, Harry eventually seated himself. Remus held still all through, forcing Snape to do the same, although Snape's involuntary writhing couldn't be completely contained. Then Harry breathed, "All right, move it!" in Remus ear, and began to piston in and out. Remus shoved back to meet Harry, then forward to fill Snape, and for a moment, he was back in time twenty years. With James buried up his backside, and Sirius flat on his back under them, legs wrapped around both of them. The way Harry went at it, there was no doubt left whatsoever in Remus' mind that he took after his father.

Such intensity couldn't last too long, and Remus had pulled his balls until that move didn't work any more, so when he felt orgasm build again, he called out, "Gonna come!" Harry shoved suddenly all the way in and held him there, shoving Remus as deep as he could go in Snape, then Harry wrapped his arms around both of them.

"Severus," Harry cried, his arm moving up and down, and Remus heard the sound of snaps flicking open, "come now!"

With the bindings gone, Snape came like a fountain, arching and bucking as his prick sprayed semen over the bed, his chest, down between their legs, freckling Remus and Harry's knees with the mess. He howled until his voice broke, and Remus joined him as Snape's arse turned into a milking machine around his deeply-embedded prick, sucking his balls dry and begging for more. Harry clutched both of them against him, his hands hard against Snape's belly, his groin clamped to Remus' arse as he spasmed, filling Remus with nearly as much spunk as Snape spread all over the bed.

Eventually they collapsed, Harry rolling off to one side and Remus forcing himself off to the other. Snape muttered a few words and the chains at his feet and ankles disappeared. Harry spooned up behind him, biting and kissing the side of his neck, and Snape looked blearily at Remus.

"You mean you could've gotten out of them any time?" Remus asked, slightly disappointed. Snape tried to glare at him, but he all could manage was a smugly well-fucked expression.

"I could, but where's the fun in that?"

Remus could only agree. Then Snape surprised him by reaching out and pulling him into a snug embrace. Harry lifted his face from Snape's neck long enough to reach over and close his mouth over Remus'. He tasted of sweat and Snape, not a bad combination, and Remus enjoyed a nice long snog before Snape began to make little whining noises. Breaking off the kiss, Remus grinned at Harry, who grinned back, then swooped down to kiss Snape until there was no more air left for whining.

When he came up for air, he pecked Harry on the nose, licked Snape's lips one more time, then extricated himself from their combined embrace. Snape looked calculating; Harry looked confused.

"Aren't you going to stay?"

Remus glanced down to see a silent invitation in Snape's dark eyes mirroring the spoken invitation from Harry. "If I do, Sirius will come looking for me."

"Then by all means, do go," Snape immediately said. Harry bit him. Snape yelped then subsided, lip stuck out in a pout that was ridiculously sexy.

"Stay, Remus. Do," Harry pled nicely.

Remus gave them a lopsided, decidedly wolfish smile. "Next time," he promised. Then he gathered his clothing and stepped back out into the hall. Glancing over his shoulder, he saw that Harry had pinned Snape to the bed, lying half on-top him and kissing that pouting lip like he was trying to devour him. Grinning at the portrait as he passed, Remus noticed that the lady in the picture had fainted, a blissful smile on her lips. Shaking his head, he climbed silently down the staircase and made his way back to the chambers he shared with Sirius. He had a lot to tell him.

When he was done talking, they had a promise to keep. He, for one, was looking forward to it.
