Authors Note: I am very fond of the Alpha/Omega trope, and decided that it was lacking in the Dumbledore/Snape ship. I decided that when I finally got around to attempting this trope, they would be the source of my inspiration.

I had a lot of fun writing this, perhaps more then was decent; I hope that you enjoyed it as much as I did.

For the past five years, Albus Dumbledore often found himself being surprised by Severus Snape (both pleasantly and unpleasantly). Whether it is that the young man, now freshly turned twenty-six, managed to comfortably stable himself at the healthy weight of one-hundred and forty-five pounds, or that he'd taken to posting stricter rules in the Slytherin common room; surprises of all sorts abounded where the young dark man was concerned. However, those surprises in no way prepared Dumbledore for the surprise that his Potion's Master greeted him with at the beginning of August.

Hogwarts Castle was relatively silent, its corridors empty, and its chambers vast and echoing as a cavern. Many of the Professors, those who had residence outside of the school, were only just returning from their summer holidays. Snape, though having a place of residence in London, did in fact, live at the school; at least for the time being. In the beginning of the early years, Snape had expressed his desire to leave the school during the summer holidays, but Dumbledore had not permitted it; back then, there were too many risks with permitting the younger man out of his sight for long periods of time. In the present however, Dumbledore had stated several times, that should Severus ever wish to leave over the holidays, he was free to do so; Snape never did. Not for long anyway. He would sometimes leave for a day or so before returning to his lodgings inside the magic castle. This was one of those times.

Severus had left the school in the middle of June, and Albus had patiently awaited his return, not even bothering to check in on the younger man; he felt that after five years, he knew Severus better, and Severus knew himself better, and Albus was certain that he could trust Severus's judgment. Albus often found himself wondering why Severus bothered to return to Spinner's End, the desolate and gloomy place of his abused childhood; but he never asked. He felt, that if Severus wished to enlighten him, he would in due course.

August fourth was a warm bright summer day, and Albus found himself leaning back in his chair gazing dreamily out of the window towards the grounds rather than going through his mail. His desk was littered with letters, which he really ought to have been replying too, but the warmth, and the sunshine seemed to have drifted through the window with the sole purpose of befuddling his brain, and making him sleepy. His brain was jarred back to attention at the sharp rapping knock on his office door.

Straightening up and blinking several times to clear his rather glazed vision, he bid the guest enter. He was pleased to see Severus stride into his office, the door closing behind him of its own accord as he approached the desk. The summer heat seemed to have affected the otherwise unflappable man before him; gone were the billowing black robes, and tight form fitting high collared black shirt with far too many buttons; replaced, instead, with a much simpler dark gray button up shirt. Though it was a nice change, Albus still thought that it looked far to stiflingly hot to wear; the long sleeves were, of course, rolled all the way down, and though Albus knew the reason for this, he could not help but feel bad that the young man couldn't even expose his arms in hopes of releasing some of his body heat.

"Ah, Severus, so you've returned." He greeted merrily, smiling up at the younger man, who he did not fail to note, had not taken his regular seat. Severus did not return the smile, but did nod curtly, his pale hands clasped behind his back. Albus knew that without his billowing robes, the young man didn't quite know what to do with his hands.

"Yes, Headmaster."

"Now Severus," Albus chided, though his smile remained just as merry, and his eyes just as kind as he surveyed the younger man. "Haven't we had this discussion before? You are free to call me by my name when we are alone in each other's company."

"Yes, Headmaster, but this is not a social visit. What I have come to discuss with you is of professional concerns."

"Oh?" His brows rose slightly. Certainly they were not to discuss his most recent denial of Severus's request to teach Defense Against the Dark Arts? Albus felt that the new term was still too far away for that argument; though he did not doubt that it would eventually come, like it did every year.

"As always, with the end of summer fast approaching, I would normally take this time to finish up my preparations for the new term, as are most of the other teachers. And since working on preparing for the new term constitutes as work, pay will begin again." Albus nodded, he knew all of that already. Pay would begin circulating again at the end of the week, as it did every August. Albus was not quite sure where Severus was going with this, though he did fleetingly wonder if the young man was going to ask for a raise; he certainly deserved it, in Albus's less than humble opinion. Severus was an extremely dedicated worker, and even gave Minerva a run for her money. Albus had long since voiced his opinion to the school governors that the teaching staff at Hogwarts deserved a higher pay grade. "I would however, like to request an additional week off."

Albus was surprised. He certainly hadn't expected that! For the five years that Snape had worked at the school, he had never ONCE requested time off; it was not uncommon for Minerva, or Poppy, or even Albus himself to have to wrestle Severus into bed when he came down with something that could not be quickly cured. The man was a hard worker, and did not seem to enjoy time off.

"An additional week? Well, of course that can be arranged, my boy. Though, I am curious about this request. May I inquire as to why you are asking for additional time off?" He asked casually, opening his desk drawer and pulling out a piece of parchment and signing it without hesitation. Severus's track record of always finishing his preparations early gave Albus no reason to deny the other man's request; he didn't doubt for a second that this additional week would not impede the other man in anyway.

"For personal reasons, Headmaster," Snape stated, clearing his throat very faintly. "and I would like to leave it at that, if you please." Albus accented with a smile, and handed over the parchment to Severus, who took it and tucked it into his pants pocket. "Thank you, Headmaster."

"Of course." Albus found, as the other man turned to leave, that his curiosity was only more peeked. What personal kind of reasons would keep Severus from his work? He looked to be in good health, and Albus hadn't heard of any emotional outbursts, or mental breakdowns; though neither would have surprised him. Severus was, unfortunately, a very broken individual. He was a long suffering, and haunted young man; Severus had had many breakdowns and outbursts during his early days as a Professor, and though he had long since grown into his position, Albus always kept a weary ear and eye out for signs of strain.

The following days had professor's and ghosts flitting in and out of his office, discussing with him things that needed looking over for the beginning of the new term; or complaining about things that needed fixing, tweaking, or merely blowing off steam due to jitters and frustration. Albus took it all in stride, and helped where he could. He had always had a fondness for the teachers of the school, though most of those he had originally worked alongside during his own time as a Professor at the school were gone now, his fondness had stretched out for almost every Professor who entered the school; almost.

There were some teachers Albus would have rather forgotten, but knew he never would. He did his best not to think to ill of any of them, after all, and he had to remind himself of this fact often, they were younger than him. Albus would, on occasion, forget that he was quite a lot older than his colleagues; he'd taught most of them himself. Thus he had to remember, he had more life experience, and though their experiences were no less important, he had to remember that his age gave him better means of coping; most of the time.

After a long afternoon sit down with Minerva, who he counted as one of his closest friends at the school, Albus felt that it was time to get out of his office, and stretch his legs. Too often he found that he'd cloistered himself up in that office; and for a man who had trouble sleeping, found that its square footage not sufficient enough for long late night pacing.

With no destination in mind, he merely meandered, letting his feet take him wherever. He would occasionally come to pause, having come across a teacher, or ghost, or even Peeves the Poltergeist, but after exchanging a few words, he would begin again on his aimless wanderings. It wasn't until four in the afternoon, and Albus reentered the castle after a long roaming walk out in the grounds (and a very long stop to chat with Hagrid), that Albus realized that he hadn't seen head or tail of Severus since their brief encounter in his office three days previously. This surprised him.

Yes, Severus had requested an extra week off, but as far as Albus knew he was still in the castle; and at this thought, his curiosity was once again peeked. What exactly was Severus doing if he wasn't working? Sleeping, perhaps? He certainly could use the extra rest, as he got very little as it was. But somehow, Albus couldn't figure that, that is what the time off was for.

Deciding that he'd just, pop down to the dungeons to look in on his charge, if only to assure himself that the young man was at least eating, he made his way towards the steps that lead down from the entrance hall to the dungeons. As he easily navigated the darkened corridors, Albus concluded that perhaps Severus had merely elected to stay down in the dungeons to escape the heat; the corridors were considerably cooler than the rest of the castle, bathed in sunlight as most of it was. He felt a little silly, not having thought of this.

Remaining in the dungeons was not only cooler, but would give Severus prime opportunity to lose all of the layers he wore everywhere else. But even so, despite this most likely being the cause for remaining beneath the school, it did not explain the extra week off, and Albus couldn't bring himself to simply turn around and return to his office; he wanted to know, and so, sooner rather than later, he found himself standing outside of Severus's office. He knocked; more out of sheer politeness than necessity. Albus had many a times simply traipsed in on his charge, starting week old conversations where they'd left off, and helping himself to any drinks the potion master might have on hand. Usually brandy, though on occasion he would find vodka, but only on occasion; he knew that Severus had an aversion towards the stuff, and though the younger man had never expressed his aversion, Dumbledore knew; Severus's father had been a great imbiber of vodka. When there was no answer, Albus figured that there were two possibilities (well three if he were perfectly honest with himself);

One, Severus was not in his office but his private quarters and might not of heard him. Two, Severus might not be in his office, or private quarters. And the third, Severus might simply be ignoring the door (a highly likely possibility that Albus chose to ignore entirely.)

Deciding that his curiosity outweighed any feelings of guilt about barging in on his Potion Master's free time, Albus simply entered the office. It was as dark and gloomy as it had been the last time Albus had been there; which had been quite awhile ago. Severus always attended him (whether for drinks, late night tea, small meals, or any other number of circumstances) in his tower office.

Severus was not in his office. Moving across the room towards the niche in the wall that he knew was the concealed and enchanted entrance to the younger man's quarters, he dealt with the spells laid upon the wall and muttered the password knowingly. He had access to all of the teacher's private quarters, as well as the house dormitories; though he rarely if ever visited any of them. He'd actually never been in these quarters while Severus occupied them. And again his curiosity was peeked. What would these quarters look like with Severus as an occupant? When Horace Slughorn had lived at the school, nearly six years ago now, the room had been bright, warm, with gaudy decorations and far too many luxurious comforts in Albus's opinion; but he expected no less from a man like Horace.

Stepping into the largest room of the quarters, which usually played as living space, Albus glanced around. The room was dark, only lit with the faint green light that spilled in through a single small window that looked out upon the lake. The room appeared to be half living room, half library. There was a dark armchair near the fire, and a two person sofa; Albus wondered why that was there, because he could hardly imagine Severus entertaining anyone; though he supposed it would come in handy should Severus ever need to bring a student, or a parent there to talk. Crossing the simple room, he paused at a dark door he knew lead to the smaller room, which would have plaid role of bedroom. The only other door led to a short hallway that would no doubt take him to the loo and Severus personal potions room. Knocking on the door, he waited (longer than he had outside) politely. No response came. He was about to accept that Severus was indeed out of his quarters, when a faint noise met his ears. Frowning, he knocked again.

"Severus?" He called. "I was merely looking for a word." He said through the door, but there was no more sound, and no one to let him in. Frowning still deeper, he opened the door and stepped inside. The bedroom was far darker than the living room, the only source of light two deeply gutted candles hanging on the far wall. The room was decorated simply, with a small wardrobe in the corner, a chest of drawers, a small desk, and the bed; which is where Dumbledore located Snape.

The top covers had been kicked aside, leaving them hanging half off the foot of the bed, and the sheets were rumpled and winkled as though the man upon the bed had been doing a considerable amount of tossing and turning. The man in question, lay sprawled on the bed, obviously in a deep (but restless) sleep, completely naked, and skin flushed and sweaty. Though he was a bit embarrassed by looking, there was really no way to avoid gazing (even if only for a moment) at the hardened cock jutting from between the younger man's legs.

It wasn't until Albus had regained himself a bit that he became suddenly aware of the alluring scent on the air. He sniffed curiously, his mind buzzing at the smell, and making him wonder why it smelled familiar. Then, with a deep inhale, a glance at the man on the bed, and then a quick look to the desk where a tall potion bottle stood half full, Albus had his answer. Severus was in heat.

The realization seemed to hit Albus like a punch in the gut; though he was sure that the smell of sex, sweat, and hormones coming from the younger man was really the cause. Severus was an Omega, and Albus marveled that the younger man had managed to keep that secret away from him. He couldn't help but admire the younger man who he watched, almost cautiously, but also fondly from the doorway. Albus had plunged into that mind, which had willingly opened for him, on many occasions; had been offered all of Severus's thoughts, and memories, both good, and bad. Albus had never thought for a moment that the younger man had managed to hide anything from him; but it seemed that Snape was perhaps, a far better Occlumens than Albus had given him credit for.

While his mind buzzed dully, and his lungs seemed to draw in the alluring smell of the other man, Albus felt a sense of calm wash over him. It made perfect sense that Severus would wish to hide this fact form Albus; it would have been simple pride, and survival instincts. Alphas, Betas, and Omegas, were in this day and age, very rare. As the bloodlines diluted over the thousands of years, fewer witches and wizards presented signs of the Elder Race; which was just a silly term coined by lack luster Historians who didn't really understand their own ancestry. Like blood status, which had an unfortunate hold over the wizarding community of the day, and seemed to govern how they worked together; so had the presentation of one's 'gender'; Alpha, Beta, Omega; the original genders of the magically possessed of the long forgotten and mostly tainted past.

Albus, who had, once upon a time, been caught up in blood status like many other wizards and witches, found the gendered system of the past just as foolish; of course, as an idiotic young man with far too many ambitions, had he had the knowledge he had now he probably would have been swept up in the grandeur of his 'gendered' status as he had been with his blood status, and dreams of Hallows, and conquering what he'd considered to be the lesser race; muggles. But, he was older now, wiser, and certainly hoped he'd learned from his foolish fact that Severus was an Omega didn't bother him in the slightest; nor did it lesser his opinion of his Potion Master, in fact, if anything, it made him respect the young man even more.

Snape stirred slightly on the bed, shifting into a slightly more comfortable position, and releasing that same faint sound Dumbledore had heard outside; a moan. Albus was drawn out of his pondering, and blinked, his eyes focusing once again on the naked man. Though he'd been distracted by his own thoughts, which often ran wild, he was not entirely unaffected by the naked man, or the heavily hormone laced air filling and suffocating his lungs.

His own body felt tight, strained, and a little warm, though he wasn't surprised by this. He didn't think that any Alpha could resist the alluring scent of an unmated, unbounded Omega in heat; even one who had long since taken suppressants like Albus.

When Albus presented as an Alpha at age sixteen, he had started taking suppressants for many reasons; One, it kept his rut at bay, which was far kinder on an already hormonal teenage body; especially since Albus did not know, nor did he have access to any presented Betas or Omegas. Two, it also suppressed his own domineering scent, which should he have ever come across a Beta, but especially an Omega, would have been suffocating and strong. Even by Alpha standers his natural scent markers were strong; Albus had a theory that it was because he was rather powerful.

He had not come to this conclusion quickly, doing his best to study, and learn, and figure out some other reasons as to why his scent may be stronger than another Alphas. He did his best not to toot his own horn as it were. He was also lucky to have had a friend such as Nicolas Flamel, who he learned was also an Alpha, to help him with his theory. Flamel had had a very powerful presence and smell as an Alpha, and would not have been easily missed had he not taken suppressants, but even so, Albus had felt neither threatened, nor overly bothered by the other Alpha; whereas Flamel had voiced that Albus's scent had stirred unease, and even aggression in him when he'd first smelt it. Which, in both of their opinions, proven that Albus would have been considered the more dominant Alpha of the two.

Crossing over towards the desk, Albus picked up the potion and sniffed it; it was obviously a sleeping drought, and Albus couldn't help but sigh as he set the potion back down and turn his attention to the sleeping man on the bed. Now that he was much closer the smell of the younger man seemed to grab him, and it seemed, had no intention of letting him go. His own body seemed to strum as his system attempted to fight off the suppressants, desperate to respond to the hormones of a needy Omega.

Albus let his eyes roam over the younger man's pallid body, and to his swollen cock. Severus's cock was rigid, swollen, and a deep angry red-purple blush; the glands of the crown had pushed a little past the foreskin, though not entirely, and was leaking heavily against the young man's abdomen. And even though Albus could not see it (he could smell it), he knew that there was also a faint leaking of fluid seeping from between the other's taught cheeks; his body doing its best to lubricate his entrance in anticipation of being plundered.

"Silly boy," Albus sighed, unable to keep the fondness out of his voice. Moving to the bed, he settled himself beside the younger man, drawing him close and holding him.

"Silly, foolish, clever boy." Though deep within the grips of the sleeping potion, Severus shifted again, pressing into the warmth of the other's body, another faint moan escaping his throat. The presence of another body, of warmth against his side, caused Severus's neglected cock to jerk slightly smearing pre-cum against his pale skin. How could Albus ignore such a woefully ignored cock? Especially one that wept so nicely, begging to be touched?

Admittedly, Albus wasn't entirely in his own sense; but he had enough presence of mind, and enough suppressant in his system, to keep him from simply spreading those pale thighs and plunging into that wet heat; claiming the Omega as his. The Alpha in side of him, which stirred feebly and sleepily, was not opposed to the idea; Albus already owned Severus's life, his freedom. Why not his body and heart as well? No. Albus wouldn't do that to Severus. It would be too cruel, and the boy had known nothing but cruelty his entire life; Albus couldn't take the option of someday finding a lover to bond with from Severus. He was still young, only twenty-six, there was still time for him to find someone. Albus would however, lend a helping hand; after all, servicing an Omega in heat, was not the same as claiming an Omega as his.

Slipping his hand from the younger man's shoulder, he reached down and wrapped his fingers around the other's prick. Severus was hard and throbbing in his hand and Albus couldn't fathom why Severus would try and simply sleep through his heat; that was so harsh and cruel on the body! He didn't even need to stroke the other man; once his fingers tightened around the throbbing member it erupted.

With a gasp, and a low whine, the young body beside him stiffened and the cock in his hand spasmed and jerked, shooting long streams of seed across pale naked skin. Albus couldn't help but smile; the hormones were making him feel a bit giddy. He couldn't help but loving the feeling of the cock throbbing in his palm as the other spilled his seed; he couldn't help stroking the hard shaft and milking what he could from the other man. When was the last time Severus had cum like that? When was the last time he'd relieved his balls, taught and full, and oh so tempting? Had he relieved himself before taking the sleeping draught? Albus highly doubted it.

It was hard for him to imagine Severus touching himself like this, wrapping his hand around his own prick and stroking it, rubbing it, jerking it. Albus's own member stirred feebly between his legs. He wondered how long the suppressant would hold out. He hadn't taken it yet this month, since his scheduled rut wasn't until September he'd been putting it off. The closer to a rut, the more potent the suppressant would act; and Albus had always waited to take the suppressant until a week before his rut. While he attempted to do the math where Severus was concerned, he swiped his fingers through the other mans spilled cum absentmindedly, drawing his fingers to his lips and sucking them gently.

He continued doing this, not entirely aware that he was doing it; gathering up the other's spent spunk and then sucking it down. If Severs had been taking suppressants, which he obviously had, Albus figured that Severus would have probably been on the suppressant for some time. Unlike Alphas, who only went into rut once a year (though they could be enticed into rut by a needy Omega), Omega's went into heat every six months. And assuming that Severus had been taking suppressants since he'd presented, probably anytime between fifteen and seventeen, then Albus could only come to the conclusion that Severus had been on the suppressant for nearly ten years. Which he found rather alarming; suppressants could be dangerous and damaging to an Omega's body if taken for too long.

The longest advisable period for taking suppressants without going into heat was two years; then the Omega is advised to get off the suppressant for one heat before continuing on again. Albus wondered how many heats Severus had permitted himself; probably not many. Given the fact he'd joined the ranks of the Death Eaters right after leaving Hogwarts, he probably used the suppressants religiously to avoid detection. And then of course, when he'd switched sides, everything had been so chaotic, so busy; there would have been no way for him to get off of the suppressants and permit himself a heat. Albus couldn't help the nagging feeling that this might very well be the first heat in which Severus had permitted himself to have. The thought pained Albus, forcing him to wonder what damage had been done to his charges body over the long years.

Though his cock had wilted slightly, it didn't all together flag; and Albus knew that it would take no time at all for that lean pillar of flesh to fully harden again and begin to beg for more attention. The younger man trembled faintly against him, his body was still burning in the grip of his heat; his orgasm only stoking the fire in his belly and encouraging more lubrication to seep between his cheeks. Albus inhaled; his own stomach clenching as a hunger for something besides food clawed at his insides.

The musky, spicy smell of the slick far more intoxicating then any Spirit Albus had ever ingested. Stroking the other's half hard cock for a moment; he let his hand slide farther down, palming the heavy balls and rolling them in his hand before dipping between pale thighs. Without hesitation, Albus slid his index and middle finger into the other's wet entrance. His fingers sank to the knuckle before the muscles tensed and tightened; a faint gasp followed by a needy whine escaped the sleeping man.

Albus waited, his patience dragging while the muscles flexed and struggled against the intrusion of his fingers; that wet heat seemed to grip him, whether to push him out, or pull him in he wasn't sure. After a moment however, patience all but dashed, he sank his fingers as deep as they'd go before beginning a pumping rhythm. More slick began to coat his fingers, and escape with each withdrawal, till he was able to slide in a third finger, stretching the other man open more still.

Severus whimpered and moaned, a wrinkle forming between his brows as he gasped in his sleep. Albus found himself whispering sweet nothings against the other's temple between soft kisses, his fingers thrusting quickly in and out of the other's needy heated body with relish. And even though his responses were sluggish due to the potion keeping him in a dreamless sleep, Severus's hips did their best to push against those fingers, thighs spread, pleading to be filled and rutted against; begging for the only thing that could keep the burning in his insides at bay. Severus would have preferred an Alpha's cock to be filling him, stretching him, filling his belly with seed, then fingers that couldn't scratch the itch, but only rub it. Albus would have preferred to be filling the young dark man with his cock, which had lengthened and hardened beneath his own robes, pulsing madly.

The suppressant wasn't going to last much longer, and the part of Albus that could still think clearly was warning him, warning him to pull away, to leave before things got out of control and he did something he would regret. But how could he leave Severus alone? The poor boy was absolutely writhing against him, whimpering, and whining, begging for relief from his discomfort. He couldn't leave him like that! He needed him! And Albus had promised the boy years ago, that he'd always be there to help him; he couldn't break that promise now.

With a growl that he couldn't quite identify, Albus sat up, his fingers still plunging in and out of the other's body. His grip and sense of responsibility and of 'right' and 'wrong' was slipping, and so he had to act, now, before it was too late. Sitting over the shorter man, fingers pumping roughly, Albus wrapped his free hand around the other's cock, which was once again rigid and flushed, the first beads of pearly precum appearing at the slit. With a second growl he had less hope of identifying; Albus leaned down and swallowed the other's prick till his lips met his own fist clutching the base of the other's member.

The loud keening cry that escaped the other man as Albus sucked him mercilessly, fingers pounding his insides, was almost enough to make Albus cum. His cock thrummed and pulsed in rhythm of Severus's own as the man was brought to a second orgasm. Albus would have loved to plunge his cock into the boy at that moment, his entire body taught and pulsing through the shock of release; would have loved to force his way into that wet heat, knot swelling and plugging that twitching hole till they were locked together and he was coating those flushed insides with his spunk.

But with blinding speed, and confused swirling thoughts, Albus found himself instead, back out in Severus's living room/study, the bedroom door slammed, cutting him off from the other man. Albus stared at the door for a long moment, not completely sure how he'd come to be on this side of it, but quickly turned away. He couldn't trust himself, not now. His own cock had begun leaking between his thighs, and he knew, from the pounding in his veins, and the burning in his lungs with each breath he took, that his suppressant wasn't going to be able to hold back his rut.

Though he may have moved to leave, instead of heading for the dungeon corridor, Albus headed for Severus's personal potion store room, lighting the torches on the walls with a mere flick of his wrist as he began perusing the shelves. It took him longer than it should have to locate the premade calming drought, but once he did he unstoppered the phial and took three large swigs of it. It wouldn't work like the suppressant, to prevent his rut, but it would help keep him in his senses; calm his mind, and emotions, and help him not simply take the man in the other room by force.

Setting the potion back on its shelf with a trembling hand, he turned and rested his back against the stone wall, parting his robes and dropping his pants in one fluid motion before wrapping his hand around his own straining erection. He pumped it quickly, harshly; he could feel the potion beginning to spread in his system, the warmth developing in his mind and chest beginning to rival the burning firestorm churning in his gut.

It only took a few rough strokes before his climax hit him; with a loud groan his body stiffened and his cock erupted. He forced his hand to continue tugging at his spurting cock viciously, gasping as his body shuddered, and the knot began to form and swell at the base of his length. The knot, that was never distinguishable while on the suppressant, continued to swell until it was bulbous and tight, trying to lock him to a mate that did not exist; trying to insure that he would be able to fill his mate with every last drop of his seed; trying to assure that there was no way for his mate not to become heavily impregnated with his offspring. With a piteous whimper that caught in his throat, Albus tightly locked his fist around the knot, which pulsed and throbbed as more cum continued to shoot out of his aggressively hard cock.

Eyes tightly closed, Albus did his best to remain upright as his body strained in its prolonged orgasm; he'd forgotten how exhausting and taxing his rut could be. Forgot how hard his cock got, forgot how much he'd cum. His body, though still strong, was far less adept at handling the rut as his seventeen-year-old body had been. Once his cock had stopped pulsing, and he could breathe again, Albus opened his eyes, gasping slightly, and sweat clinging to his skin as he trembled against the wall. He kept his fist firmly around the still swollen knot; his cock jutted from his fingers still hard and flushed, the head glistening with beads of cum.

The floor before him was splattered with shiny ropes of his seed; far more then he could have produced while on the suppressant. He vaguely thought that he should clean up after himself when this was all over, but any thoughts of cleaning or manners were erased as his fingers twitched around the knot and he was forced to grip it tighter as another orgasm was ripped from him; his cock twitched as more ropes of cum escaped to paint the dungeon floor.

After enduring four eruptive orgasms, Dumbledore, fully robed again and only faintly out of breath, emerged from the potions store. Severus's living room had darkened considerably, and Albus estimated that it was probably nearing sunset. With a flick of his wrist, the candles and torches about the room flared into life. The living room smelt vaguely of Severus, a scent Albus was now very keenly aware of. It didn't smell of the man's heat, but simply of him. It was a rather mild spicy scent, and Albus found that it was quite pleasant to his heightened senses.

Glancing towards the bedroom door, Albus sighed. He couldn't leave Severus alone, he wouldn't; the foolish boy needed to know that he HAD options; that he needn't suffer through his heats. Besides, Albus had touched the other man and invaded his body; and even though he'd only used his hands, it was still a violation that he could not simply walk away from. Severus would have to be told, it was only right.

Crossing the living room towards the bedroom door, he only hesitated a moment before slipping back into that darkened room. Where Albus was calm, his still pulsing blood merely a simmer beneath his skin, granted a small reprieve from his rut after orgasm, Severus was not so lucky. The younger man still laid fretting and sweating upon the bed, thighs and cheeks coated in spicy scented slick, and blushing erection twitching against his abdomen.

Severus had become considerably more animated since Albus's retreat, and the headmaster was certain that it was because the sleeping draught was beginning to wear off. Albus closed the door, and crossed to the desk, picking up the sleeping draught and moving it out of the man's reach. Severus would no doubt seek out the potion upon waking, but Albus wouldn't let him go back to sleep; sleep was not the answer. Once the potion was out of reach, Albus conjured himself up a comfortable chair to sit in; despite the other man's overwhelming scent, which coated Albus's mouth and lungs like a heavy blanket, Albus remained mostly in his right mind; the calming potion he'd taken assuring him that things would be okay; assuring him that even though his rut was upon him, and a needy Omega lay in heat before him, there would be time to deal with those things. There was no reason to be hasty. It was a potion induced lie, of course, but Albus found that he was rather content to simply sit in his chair, and watch the other man hungrily.

As Snape began to come back to himself, the first thing that returned to him through the darkness of the sleeping draught was his sense of self; and the overwhelming NEED thrumming through his body was a painful reminder that he was currently in heat. He let out a groan that he could not hear, but could feel vibrate in his throat. He felt heavy; his body pressed down into the wet sheets beneath him; his skin felt irritated and sore. His muscles twitched, and he could feel the lubricant slick between his cheeks, far wetter, drenching the sheets beneath him, than he'd bargained for.

The next thing that returned to him as he slowly rose up out of the sleep induced haze was his sense of smell, and with it, the overwhelming scent of power that seemed to press him into the bed. A loud whimpering groan escaped him as his sense of sound returned to him. God, what was that smell? It was suffocating him! And yet, all he wanted to do was have the scent permanently imprinted in his nose, his lungs, his skin, his very brain!

Shifting on the bed, panting slightly as his entire body throbbed, that strange overwhelming smell filling his lungs with every breath, he blindly reached towards his desk. His fingers found the smooth wooden surface, but no glass phial. He groaned a mixture of wanton lust and frustration.

"Severus," Snape's entire body tensed at the voice, eyes snapping open, groping hand going still. It took a second for his eyes to adjust and for his vision to return to him, but when it did he spotted the man seated beside the bed; and then it registered, that smell, the powerful, overwhelming smell was coming from the headmaster. Snape closed his eyes again, and half groaned half whimpered, his body trembling slightly; in fear or lust he wasn't even sure.

The headmaster was an Alpha; of course he was. Life often wasn't kind to Severus; who'd spent his entire life suppressing his body's natural instincts and hoping NEVER to come across an Alpha. But now here they were. Dumbledore seated beside his bed, his smell both dominating and intimidating, making Snape want to both run and drop to his knees and present himself for the taking; and Snape, unable to do either, but afraid not to move, not to respond.

"Severus, we need to talk," Dumbledore shifted forward in his seat, but paused when Snape twitched, jerking away from the man and releasing what could only be described as a hiss. Dumbledore remained on the edge of his seat, gaze never leaving the younger man, who'd moved himself farther away on the bed, shaking limbs barely able to keep him propped up. Distress wafted from the Omega, and the Alpha in Albus wanted nothing more than to comfort him, assure him that he was safe, and that nothing would hurt him; but Albus had to push down that inclination. He was the cause of the distress! He was the reason that Severus was glaring so heatedly; dark eyes reflecting aggression and fear; though, and Albus couldn't help but note, the erection between the other's legs hadn't flagged in the least. "Severus, please,"

"What are you doing here!?" Snape spat, his voice harsh and broken from lack of use. He wanted to force himself to retreat further, but he'd reached the edge of the bed, and didn't think he could stand, let alone run to escape.

"I'll be honest," Albus said slowly and clearly, wanting to be sure that Severus would hear and understand him. He knew that the shock of his appearance was the only thing that had brought Severus back to himself; he also knew that this window of self-of-mind would not last long. Soon, Severus's heat would get the better of him, and he would be unable to be at all objective about the situation. "I was curious as to your request of extra time off, and wished to have a word. When I discovered you, though my first inclination would have been to leave, I'm afraid that my own instincts prevented me from doing so." He was ashamed to admit that his instincts had gotten the better of him, smothering his proper judgment. Severus, though trembling in his half raised position, continued to gaze steadily at him, black eyes glued to blue; proof that he was listening, even if he wasn't saying anything.

"My own rut," Albus continued. "Coincidently enough was scheduled to occur next month. That being the case, I had not yet taken my suppressant. The scent of your own heat," Albus found he had to swallow, his throat having gone slightly dry. "Was too strong for the nearly year old suppressant in my system to fight off. And, as it were, I have been driven into an early rut."

At this Snape's eyes widened, and a faint noise of distress caught in his throat. For the first time, he broke eye contact, looking around for any means of escape. In his panicked haste, he lost his balance, but before he could fall onto the hard stone floor, a strong hand gripped his arm and pulled him back across the bed, sheets being dragged underneath him. Though he should have perhaps been grateful not to have fallen and possibly caused himself bodily injury, all he felt was panic. Lashing out at the hand on his arm, he struggled, trying to get away from the other man.

"Severus please calm down." The request, though heard, went unregistered. Snape's mind was nothing but instinctual panic that told him to get away! This Alpha, this Alpha was dangerous! He was unbonded, something that the Alpha holding him there must have known. It didn't matter to Snape that it was Dumbledore, the man who would never have hurt him. All that mattered was that it was an Alpha, and he HAD to get away.

Struggling to keep hold of the man fighting against him, Albus's rather short patients was tested; if it weren't for the calming draught still in his system he probably would have been inclined to be more forceful then was necessary. It was only when Snape sank his teeth into his wrist that Albus locked his other hand tightly around the back of the other man's neck. The second his grip tightened the other man went slack, lying on the bed, black hair covering his face; legs awkwardly curled under his body. Albus's stomach gave a pleasant flutter as he held the still figure against the bed, his hand firmly pressed against the Omega's bonding gland at the base of his skull.

Invisible to the eyes, the gland was used to force an Omega into submission, usually used if the Omega was in danger of hurting themselves or their mate.

"Severus," Albus's voice was a little sterner then before, and the man beneath him let out a faint whimper, shifting slowly to unfold his cramped legs; the hand upon the back of his neck preventing any further movements. "Severus, I'm NOT going to hurt you. Now, please, you have to listen to me." Releasing the other's neck, Albus lowered himself back down onto the edge of his chair.

Snape didn't move for a moment, merely remained where he'd fallen. But after a moment, his brain registered what the other man had said, and with considerably more effort than it was worth, he forced himself back into a sitting position on the bed. His thighs trembled beneath him, drenched with slick. If his body hadn't already been overheated, he probably would have blushed with embarrassment at the knowledge that his body had released fresh slick when the other man had forced him down on the bed. His cock was leaking obscenely, but he couldn't bring himself to be embarrassed; couldn't bring himself to try and close his thighs, or hide his nakedness. What was the point? His mind was foggy, and his scent was practically embedded in the walls of the room; there would be no hiding anything from the man seated across from him.

"Severus, can you understand me?" Albus inquired, his voice calm once more, tone clear. It took a few seconds, but the dark haired man on the bed nodded, black eyes once again turning to blue and holding his gaze. "I must assure you Severus that I did not take you." He let this sink in, hoping that the other man understood what he meant. He seemed to; the panic and anxiety from before had gone, replaced with simple unease. The Alpha in him didn't like this either, but it was better than panic; but only just. "The suppressant remained in my system long enough to keep that desire at bay. However," and Albus had to clear his throat which had gone dry again. "I cannot claim innocence. I was drawn to you Severus, and I touched you." Snape's eyes widened slightly, but he didn't say anything, or try and bolt again; he merely sat there on the bed, sweat clinging to his skin, shivering slightly. Albus continued. "I touched your hard penis, and stroked you through orgasm." The rather clinical words tasted bad on his tongue, but Albus was doing his best to get these confessions out before either of them lost themselves again to heat and rut respectfully; the simmering beneath his skin was beginning to warm, and he knew that time was running out. "I cleaned up the evidence of your release, and then proceeded to plunder your body with my fingers, just my fingers."

Snape couldn't stop the trembling that began assaulting his limbs. He was trying very hard to keep focused on what the other man was saying, trying to understand what it meant; but it was a struggle. His cock was throbbing painfully between his thighs, precum dripping onto the tangled sheets with obscene 'plop, blop' sounds. He could feel the cleft of his ass wet and slick, an uncomfortable sensation. He could feel the muscles in his rectal canal twitching, wanting to be filled, stuffed beyond comfort, pounded and painted with cum; the other man's cum, Snape's brain added helpfully. A forceful shiver wracked his body and he gasped slightly, shaking his head, while trying to keep eye contact. The other man was talking to him, demanding his attention, and Snape wanted, no, needed to listen; he needed to understand, it was paramount.

"I thrust my fingers deep into your body, without invitation, and continued to do so mercilessly while you slept on, helpless to prevent it." Dumbledore said, and Snape's ass clenched slightly, as though his body could remember the feeling of those long slender fingers plunging in and out even though he couldn't. "And before I was able to force myself away from you, I took you into my mouth, and swallowed down everything your second orgasm had to offer." Snape couldn't repress the loud groan that escaped him, his cock twitching heavily between his thighs; he had to close his eyes to try and steady himself. He couldn't look at the headmaster any longer, couldn't help but image those fingers forcibly plundering his body, those lips parting to swallow him down. A keening whine escaped him as he forced himself to open his eyes, and draw away from those thoughts. "Do you understand, Severus?" Albus inquired.

And Snape did, he did understand. He understood that the headmaster had taken advantage of him, had touched him inappropriately, and without permission. But he didn't care; couldn't care, not right now. Maybe it would bother him later, when he could properly think, maybe they'd have words about it then, but now….

"Yes, h-head-p-professor." Snape could feel the burning in his body begin to flare up again; the shock of the other's presence, of the presence of an Alpha, wearing off. Fear was being replaced with need, pure, unadulterated need. Need to be filled, need to be dominated, and claimed by an Alpha; to be cared for. He gasped as he shifted, forcing himself onto his knees, thighs trembling as slick began dripping down between his legs. "I do…" He whined, closing his eyes. "But, please…" He shook his head forcefully, trying to keep it as clear as he could for as long as he could. "G-give me… give me the potion." He opened his eyes and looked at the potion out of his reach; the potion that would let him fall back into that dreamless oblivion.

Oh, he didn't want the potion. He didn't. He wanted the headmaster. He wanted the headmaster to touch him, to push him down, to take everything from him, anything he may desire.

"Severus," Albus could smell the rise in the other's pheromones, and his gut tightened the thrumming beneath his skin turning into a spreading heat that quickened his pulse. Severus was slipping, and Albus couldn't stop it; and if he were honest with himself, didn't want to stop it. He wanted to see the other man a trembling mess upon the bed, body spread wide for him, crying for him.

"P-please h-h-Sir." Severus stuttered, broken voice husky as he shifted to fall into his side on the bed, hair spilling out over the nearest pillow. "I n-need," his voice broke and a pained whine escaped him, his hand sliding down and wrapping around his own raging erection, pulling at it uncoordinatedly.

"Severus, I am willing to service you. You don't need to go through this alone." Albus stated, voice a little darker, more gravely then before; blue eyes narrowed over half mooned spectacles as he watched the other man pull at his sex helplessly. "I can service you with no strings attached. Nothing expected of you. No conditions. Simply a service I can give you." The younger man keened his back arching slightly as his thighs fell apart; his hand stuttered in its movements, but only slightly.

"P-please, it hurts." He whined, and that's all the invitation Albus needed.

Climbing onto the bed, and looming over the naked man; he pulled his beard together in his hand, and draped it over his shoulder as to keep it out of the way. Pushing the other's hand away he wrapped his fist firmly around the other's cock, a whimpering whine escaping the other man, who trembled beneath him, dark eyes peeking up from beneath heavy lids. There was fear there, fear of the Alpha, but something else; something that was struggling behind those dark eyes, but something that made Albus's own cock twitch as it began to harden again: trust.

Severus trusted him; trusted him not to hurt him, trusted him to help him, care for him. Severus Snape trusted Albus Dumbledore with all of himself; there were no more secrets. This was the last secret the young man had to offer.

"I've got you," Albus purred, bracing himself with his knees, and his free hand on the mattress. "It won't hurt anymore; I'll take care of you." He assured, pumping the other's throbbing cock in his hand with care; careful not to go to fast, or to hard, but just firm and quick enough that would bring the other man to the orgasm he so desperately needed.

Severus whined beneath him, eyes closing, fingers digging into the sheets as he began gasping, body tensing and twitching as his cock was pumped; a moment later, and his entire body went rigid, a cry tearing its way up his throat as his balls drew up tight and he came all over his stomach. Albus hummed happily as he continued jerking the other's spurting cock, loving the smell of sex, sweat, and Severus's unique pheromones as the younger man cried and writhed through his orgasm. When the other's orgasm subsided, Albus released the half-hard flesh, and let his hand roam over that flat pale stomach, smearing the cum before drawing his hand to his own lips.

He watched the younger man as he licked his hand clean, his own cock hard and pulsing beneath his robes. Severus moaned drawing his legs up slightly so he could spread his legs wider around the man above him, lifting his hips a bit and doing his best to try and present himself. The position wasn't exactly prime for that, but he wanted, no, needed the Alpha to know that he was wet, responsive, ready and willing to be taken. The attempt to present wasn't lost on Albus, who finished licking his hand clean before lowering his hand again, sliding down between pale thighs, and running his fingers along the drenched cleft.

Severus keened, hips jerking slightly as Albus slid his fingers down along the cleft of the his ass, coating his fingers in the wet clear fluid there. Once they were coated liberally, he withdrew his fingers, and pressed them into his mouth. Dark eyes widened, and Albus found he rather liked the look of flushed surprise on the other's face; so once he'd cleaned his fingers of the thick musky fluid, he once again dipped them between pale cheeks, coating them again so he could enjoy the flavor of the other man on his tongue.

Severus trembled, silently while Albus continued to taste him, his knuckles brushing against his entrance and making his thighs jerk slightly each time. Albus found, though he was very fond of sweet, rich things, the flavor of the younger man, though musky, and almost spicy, was not unpleasant. Albus was also keenly aware that once he took Severus, the flavor would change; and though his logical brain told him that this was probably a onetime thing, the Alpha in him hoped very much that the young omega beneath him would permit him to service him during more of his heats. Deciding not to take a chance, Albus gripped the other's legs behind the knee, and pushed, forcing the paler man to curl slightly while Albus lifted and parted his legs; Severus let out a small noise of complaint at the position, his weight being forced on his upper back and shoulders, but Albus didn't care.

The new position was perfect; exposing the other's spread cheeks, and glistening hole. Shifting, so that the other's legs were braced against his shoulders, freeing his hands so that he could support the other's taught rear, Albus lowered himself and nosed at the other's balls, inhaling the smell of pheromones and sex. He could feel the other man trembling violently, and hear the soft noises caused by the faint tickle of his mustache and beard against perineum and cheeks. Lowering himself still further, where Severus's scent was strongest, he plunged between taught cheeks, and swiped the flat expanse of his tongue against the other's entrance.

If he didn't know better, the scream that escaped the other man could have been construed as pain; but Albus knew better. Lapping along the cleft of the other's ass, cleaning up old and new slick, he enjoyed the loud noises that his charge made; each yip, moan, and scream going straight to his cock; which hung hard and heavy between his legs, precum soaking through the cotton material of his pants. Once he'd cleaned the other man's cleft and thighs, he slid between the other's cheeks and began licking and sucking at the twitching entrance, catching the new slick as it was produced.

Albus was certain that he'd never tasted anything quite as delicious as HIS Omega's virgin lubricant; for even if no bond was formed, there was no doubt in Albus's mind, the Alpha's mind, that Severus was HIS. He pushed his tongue into the other's body as far as he could, sucking as best he could against the quivering flesh while his tongue sought out more of that delicious flavor.

Snape couldn't hold back the loud moans and cries of pleasure as the headmaster disappeared between his thighs, tonguing his entrance with vicious enthusiasm. Snape was almost certain that the man desired nothing more than to devour him from the inside out; a thought that only made him whine and the burning fire in his gut to burn even hotter. He clawed at the bedding, fisting the damp and crumpled sheets in his hands as his body tried to squirm, but the powerful hands proved testament to the headmaster's rather impressive and prodigious strength; all he could do was tremble and twitch, throwing his head back against the pillows and attempt to drag much needed oxygen into burning lungs.

His prick, which never seemed to go completely soft, was once again straining against his stomach, smearing and dripping precum against his curled stomach. It throbbed, and ached, but Snape didn't dare touch it. He didn't know the Alpha's temperament, and though he knew Albus to be a patient individual, he was also aware of the man's darker side; the side that could tear him down with a mere look.

Snape groaned toes curling as his legs tensed against the other's shoulders. Yes, Albus was a kind man, a gentle man, but he was also powerful, and manipulative, and clever; so, so very clever. Snape had been on the receiving end of both sides of the headmaster, and knew that the man would have far less control over himself with the Alpha in rut. The mere thought making Snape's spine want to snap, to arch into the ministrations against his entrance. Oh it wasn't enough! He needed the other's cock! Needed to be mounted, viciously rutted into, and bred! But it didn't seem that the headmaster had any intentions of moving from his current place between his thighs; perhaps he was content to merely lap up the slick Snape was producing; a bodily response to the heat, and especially to the Alpha, that Snape couldn't control. He couldn't stop that flow of liquid, no matter how tightly he clenched his insides; it continued to leak, gushing inside of him for the pleasure of the Alpha.

He couldn't take anymore, and with a high pitched scream that tapered off into loud grunting groans Snape came; cock jumping against his stomach as he spilt against his chest, and more slick coated his canal.

Albus was a bit startled as Severus came, legs tightening around him, and a fresh surge of slick gushed from the other's entrance, coating his tongue, lips, and whiskers. He stilled, mouth pressed against that spasming ring of muscles, while the younger man trembled and moaned through his release; fresh scents of sex and spunk assaulted his nose. Once the other man fell quite and still, Albus began gently lapping between pale cheeks again; slower this time. The trembling that had subsided slightly started again, and a whine escaped the younger man.

"S-sir, no, p-please," a gasp, and a whine. "N-no more… p-please… n-not enough…." Albus continued to lap at the other's entrance, while carefully shifting so he could lower the other's legs from his shoulders and back onto the bed. Meeting lidded dark eyes for a moment, he continued his lapping; pressing his tongue firmly against perineum, then laving the other's heavy balls with a wet tongue. He drew one testicle into his mouth and suckled on it gently when he received a faint hiss from the other man, only appeased when he received a whimpered moan instead. Releasing the little orb, he continued his movement upwards; till he could lick a wet strip along the length of the other's wilted cock.

Severus's skin was salty with sweat and cum, and Albus drew the limp flesh into his mouth and sucked gently. Severus let out a cry, which he tried to stifle, hand pressed against his mouth and teeth digging viciously into knuckles. Albus didn't stop, but continued to gently suckle on the other's sex for a moment, listening to the smothered whimpers and enjoying the heavy, almost painful throbbing in his own cock; which he could feel was leaking obscenely within the confines of his pants. Sharp blue eyes flicked up to meet glistening black.

Severus gazed back steadily at him, brows drawn together, and eyes tight and glistening with tears. Albus released the other's dick with a slight 'pop' and moved further up the pale body, removing the knuckles from between slightly crooked teeth and gently kissing the reddened indents there.

"My precious Severus," Albus sighed, voice rough with lust. Tears escaped and slid down flushed sallow cheeks when dark eyes closed, and Albus gently cradled the other's cheek in his hand, running his thumb beneath one eye to catch the tears. "Beautiful," He purred. "So beautiful, perfect, my lovely, lovely boy."

"P-p-please,"

"Shh." Albus pressed his lips to the other's kissing him rather chastely before withdrawing. "I've got you love." Severus let out a whine at the praise; disagreeing with it, but also wanting to hear it.

"Please, Sir, I can't take anymore, please," Pale, potion stained fingers gripped at Albus's robed arms, and dark glistening eyes opened again to meet his. This was the most alive Albus had seen those eyes in a long time; usually Severus's orbs were as black and as empty as tunnels, due to his constant practice of Occlumency. But now, now they reflected everything, every emotion, every thought, everything that the younger man was feeling. "Inside, please, sir. I need you inside." Gripping the side of the other's face, Albus pressed a firm kiss to those pale lips, before drawing back, blue gaze darkened and sharp.

"On your knees, my boy."
