A Birthday Surprise

Disclaimer: All Characters belong to JK Rowling. I make no money from this.

A/N - This fic was among the first I ever wrote, and was, I think, the very first NC-17 fic. So, if it\'s a little rough (a bit like Snape later on), I apologise! It\'s also kind of a parody fic, so it shouldn\'t bee taken too seriously...... ;)

Sirius had had what he believed was a brilliant idea. He had discovered some time ago that Snape’s birthday was within a few days. Sirius thought that it would wonderful to celebrate Snape’s birthday. However, it appeared that he was possibly the only person who would be celebrating it. When he mentioned it to the staff at Hogwarts they had all, politely, informed him that Snape *never* celebrated his birthday, and usually took exception to anyone foolish enough to make such a suggestion to him.

Sirius, however, was undeterred by this. He decided that Snape really should celebrate his birthday, and if it was just the two of them at the party, that was fine – he was certain he could come up with enough suitably *interesting* ideas to prevent the two of them from getting bored.

Consequently, he spent a large part of the next week or so bartering, bribing and downright pleading with the house-elves to ensure that he would have everything he needed for his plans.

Snape’s birthday fell on a Saturday, which was just perfect for Sirius’ plans. It meant that Snape would spend most of the day working either on potions, or marking the assignments he had set the previous week. It also meant that Snape had no reason to be up and about early the next day, because he intended keeping Snape busy until well past midnight.

As soon as Snape left for his laboratory the morning of his birthday, Sirius crept into his rooms and began to prepare them for that evening. Throughout the day, the house-elves popped in and out, either to assist Sirius, or to drop off something he had asked for, or, on a couple of occasions, just to see what was going on.

Almost everything was ready. The satin sheets were on the bed; red candles burned on every available surface; the air was lightly perfumed; there was a fire burning in the grate; pillows were piled high around the low table in front of the fire that was laden with various exotic dishes, as many of Snape’s favourites as Sirius had been able to find out from elves. And there, in the centre of it all was the part that Sirius was most proud of, a birthday cake, complete with candles.

He looked at the clock on the mantelpiece. The hands read ‘Marking Essays’ and by the looks of it, Snape would be marking essays for a while yet, which meant that Sirius had time for a bath and some other, more personal, last minute preparations……

Finally, Sirius emerged from the bathroom, dressed in a green silk bathrobe. Everything was in place and all he could do was wait for Snape to return to his rooms.

After Sirius had rearranged the table settings for the tenth time, he finally heard Snape muttering the spells to allow him through the wards. Sirius fidgeted nervously. He checked that the spells to keep the food warm, but fresh were still in place, and then tried to arrange himself in what he hoped was a seductive manner over the pillows.

Snape walked into the room and stopped dead. Sirius tried not to fidget as Snape’s eyes pinned him in place, then flitted around the room, taking in the food, fire, pillows, candles and by the way he sniffed, the perfumed air. His eyes glazed a little, and then suddenly snapped back to Sirius.

Sirius gulped, heart hammering in his chest.

“What, pray tell, is the meaning of all….*this*?” Snape asked in that soft voice that Sirius had learnt could mean real danger.

“Um, well, Albus let slip a little while ago that it was your birthday today Severus, and well, I wanted to do something to celebrate it”

Sirius watched Snape carefully, but the Potions Master said nothing, he merely continued to stare at Sirius with those bottomless black eyes.

“I asked the others if they wanted to help celebrate it, but they didn’t, but I couldn’t just let it go without doing something so I tried to find out all your favourite foods, and I had to bribe the house-elves to help me, but if you don’t like it I can….” Sirius was aware that he was starting to gabble and run his words together, but he just couldn’t seem to stop his mouth from moving.

“Black”

“Er…..yes Severus?”

“You did all this, because it was my birthday and you wanted to celebrate it?” The voice was still deadly quiet.

Sirius fought the urge to put more of the table between himself and Snape.

“Yes”

Snape stood there for a second longer, as still as a statue, then a sudden heat flared in his eyes, and before Sirius could think of ducking what he was sure was going to be an unforgivable, Snape was across the room and hauling him to his feet.

Sirius tried hard not to cringe.

Snape looked hard at him.

“You did all this, for me? What do you want Black?”

“Nothing, except to help you celebrate Severus.” He held his head high and looked Snape in the eyes. He refused to be embarrassed.

All of a sudden Snape moved again, and Sirius found himself on the receiving end of a fierce kiss. Had he been able to breathe, he would have sighed in relief. However, breathing was not much of an option while Snape was apparently intent on examining his tonsils as thoroughly as he attended to his potions.

Sirius thought he was just about to pass out from lack of oxygen, when Snape finally released him. Sirius staggered somewhat, and would have fallen if Snape hadn’t still been holding onto him. Sirius blinked at Snape, knowing that he looked drugged and dazed.

“Wow. If I’d known that would be the reaction, I’d have done it a lot sooner”

Snape *growled* at him, actually growled, and Sirius felt the faint edge of fear again, sharpening the heady sense of arousal that was currently making his head swim, and his cock stiffen.

The next thing Sirius knew, he was on his back, on the cushions, with a Snape blanket over him. A second later, Snape was back to mapping his mouth most energetically, whilst Sirius was dimly aware of hands moving between them, although whether they were removing Snape’s clothing or his he wasn’t sure. All he knew was that some time later, he was vaguely startled by the realisation that they were both naked.

His back arched, and he rubbed himself against Snape. The sensation of his cock colliding with Snape’s caused him to pull his mouth away and pant.

“Oh fuck…”

“If you insist”

Sirius wasn’t sure whether he should be insulted or glad that Snape sounded so coherent and amused. An amused Snape made for a somewhat….inventive bed partner.

Sirius had intended to be the one in charge this evening, but it seemed that yet again Snape had the upper hand. Sirius sometimes wondered how Snape managed to do this so often.

“But, what about the food Severus?” Sirius managed to blurt out, not wanting to waste all his hard work.
Snape raised his head from where he was working on leaving Sirius with what would undoubtedly be a monumental love bite that it would take a scarf to hide.

“I presume you had the sense to cast a warming charm on it?” When Sirius nodded, he continued “Then it will be fine. Although…..”

Something on the table had clearly caught Snape’s eye because he sat up, smirking at the sound of disappointment that Sirius was unable to contain.

“It would be a shame to not use some of this…..”

“Eh?”

“Hmmmmm. Now, what does this do I wonder…..?”

Sirius raised his head enough to look at what Snape had in his hands. It was a can of aerosol cream.

“It’s cream Severus”

Snape raised an eyebrow

“The can sort of whips it as it comes out….” Sirius trailed off, as Snape raised his other eyebrow, and a positively wicked light appeared in his eyes.

“Interesting. So, if I hold it like this…”

Snape pointed the nozzle of the can at Sirius’ chest and squeezed the trigger.

“Arghhhhh! That was cold Severus” Sirius looked reproachfully at Snape, who merely smirked.

“Really? Well, maybe I can think of a way to warm you up again...”

He bent his head over Sirius and licked up a little of the cream. Sirius dropped his head back onto the pillows and moaned quietly.

Snape paused, and Sirius could just imagine the look of consideration on his face as he tasted the muggle confection for the first time.

The consideration clearly didn’t last long as Snape suddenly applied himself to the task, lapping up the cream with little kitten licks, interspersed with long, slow swipes of his tongue. When the first lot of cream was gone, Snape applied more, around Sirius’ nipples and across his chest. Sirius was groaning freely now.

Without warning, Snape’s mouth left his chest, but before Sirius could voice any kind of complaint, Snape was ravishing his mouth again, sharing the taste of the cream.

When Snape finally released him, Sirius was gasping.

“Ah…I…ah…take it….you..er….liked that then?” He grinned.

“Almost as much as you did, I suspect” Snape smirked back. He looked speculatively at the table, then back at Black.

“On your hands and knees Black”

“What?”

“Onto your hands and knees. Unless you’d rather just sit here and eat some of this, admittedly lovely food…..”

Sirius moved. He knew Snape would do just what he threatened if Sirius took too long. Besides, the position wasn’t exactly an unusual one, and the rewards were more than adequate.

He waited, nerves jingling, muscles tight. Snape settled behind him, and then Sirius felt something warm and liquid being trickled into the small of his back. He sucked in a breath at the feeling. Snape leant forwards and using the same kitten licks and long swipes he licked up whatever it was.

Sirius thought it was possibly a good thing that he wasn’t a cat in his animagus form, otherwise there was a strong possibility that he’d be purring by now. The smell of chocolate filled the air, and Sirius realised that Snape had discovered the chocolate fondue.

So when Snape poured the liquid further down Sirius’ spine, so that it trickled slowly down the cleft of his arse, his back arched and he hissed. The sensation was almost unbearably erotic and Sirius shivered in pleasure.

The shiver turned into a full body shudder when Snape ran his finger through the pool of liquid chocolate in the small of Sirius’ back and down between the cheeks of his arse. Sirius heard himself moan when Snape’s finger dragged slowly over his arsehole, down to cup his balls and on to stroke his cock.

“Oh yessssss”

Sirius could almost *feel* the smirk on Snape’s face. One day Sirius was going to be the one in control….just not right now.

Just as Sirius was really beginning to enjoy the feel of Snape’s attentions, the hand was removed. Sirius whined, then cringed, but before he could say anything else he felt Snape’s warm breath wafting over his back, and then hands gently separating his buttocks.

The first swipe of Snape’s tongue over his entrance made Sirius yelp and buck. He felt as much as heard Snape’s evil chuckle, and it just made him shudder all the more. He couldn’t believe that Snape, of all people, would do that. Mr Fastidious. That thought alone made him groan and his cock twitch.

Sirius was so distracted by the lapping of Snape’s tongue, now interspersed with gentle nips and suction, he almost didn’t notice when Snape’s hand suddenly returned to his cock. Sirius couldn’t move, trapped between Snape’s tongue, now pushing gently into him, and his hand, so he settled for arching his back and swearing.

“Oh *fuck* Severus, oh fuck”

Snape raised his head, causing Sirius to groan in frustration.

“If you insist…”

Sirius suddenly found he was very, very hot, and wondered if Snape has turned the fire up.

“And did you remember to leave the lubricant somewhere close to hand? Hmmmm”

“Hell yes….”

“Remarkable”

Sirius bit back his response to Snape’s sneer. He really didn’t want to break the mood, not even when Snape was looking so pleased with himself.

From the movements and sounds behind him, Snape had clearly found the lube and was preparing himself. Anticipation flowed through Sirius’ body. He never knew, with Snape, whether he was going to be the one doing the fucking, or being fucked. In truth, he didn’t care much, pretty much any sex was good sex as far as he was concerned, and Snape had discovered early on that Sirius had no problem with a little pain to add a sharper edge to his pleasure.

Snape moved back against Sirius, wrapped an arm around his chest and pulled him into a kneeling position, Snape’s knees between his. Supported against Snape’s chest, Sirius found himself panting with anticipation. Snape’s hand returned to his cock, stroking and pulling, just the way Sirius liked, long slow movements, with just a hint of a twist of Snape’s wrist. He arched, almost purring again, his hands reaching down to brace himself against Snape’s thighs.

Without warning, Snape sank down, pulling Sirius with him, until the head of Snape’s cock touched Sirius’ arsehole, as his hand stilled in Sirius cock.

Sirius sucked in a breath, skin tingling with anticipation. He waited for Snape to move.

“Is this what you want Black?” Snape’s voice growled into Sirius’ ear. Sirius’ shivering was now an almost permanent tremble he could feel through every nerve and muscle of his body. “Do you want me to take you like this? To stretch you open with my cock? To fuck you slowly until you can’t stand it any more and then fuck you so hard you’ll feel it for days?”

Sirius whimpered; there was something desperately thrilling about hearing priggish, uptight Snape talking dirty that never failed to arouse Sirius beyond all reason. Of course, the fact that he knew that Snape could, and would most likely do exactly what he threatened helped as well.

“Oh Merlin, yes. Fuck yes. Do it Snape, do it just like that”

“As you wish”

Sirius could hear the smirk in Snape’s voice, but before he could respond, Snape thrust upwards, sharply.

Sirius arched, pain and pleasure shooting up his spine, until he couldn’t tell them apart, not that he’d ever been very good at that. He grunted with the force of Snape’s thrust and the burn of his entry.

Snape stilled, and Sirius just knew that he was enjoying the tightness of Sirius’ body, and the sounds of his gasp and pants for breath, as much as allowing Sirius time to adjust and relax.

Then Snape began to stroke him again. Sirius couldn’t help himself, his hips rose, trying to capture as much sensation as possible.

“That’s it Black, fuck yourself on my cock. Show me how you want it” Snape’s voice was harsh, strained, and it drove Sirius insane to know that Snape was getting off on the thought of what they were doing as much as Sirius himself was.

After a couple of stutters, he managed to catch the rhythm of Snape’s hand, and then they were moving in concert. The pace was slow, deliberate, intense. Sirius was panting still; it felt as though he hadn’t taken a proper breath in hours. It seemed as though Snape was going to do just what he’d promised. Sirius wondered if he’d last, the thought of, combined with the slow, thorough fucking was almost enough to get him off anyway. Almost. The pace was not quite fast enough to tip him over the edge. Instead, Snape was keeping him on the edge.

Sirius wondered if it was possible to lose your mind during sex like this. He guessed that was why they called it mind-blowing.

“How does it feel Black?” Snape was almost panting himself now, ratcheting up Sirius’ arousal another notch.

“Fuck, Severus. Don’t stop, oh Merlin, please don’t stop”

Snape laughed, and it made Sirius shiver, which made Snape thrust up harder than before. Sirius groaned, and clenched around Snape.

That was all it took, this time. Snape lost his composure, and thrust into Sirius, harder and faster. His hand moved faster over Sirius’ cock, clasping tighter to increase the friction.

Sirius’ orgasm hit him suddenly. A sharp thrust and an especially vicious twist of Snape’s hand proving to be enough to send his body in overdrive. Sirius felt every single muscle as they tensed and locked. He froze, the pleasure roaring through his body and brain. Snape never stopped moving, wringing every last sensation, for both of them. Before Sirius had even managed to catch his breath; before the aftershocks had fully faded, Snape arched, shuddered and groaned as though he were dying. Any one of those things would have been enough, but all of them caused Sirius’ body to tighten one last time, flooding him with pleasure, exhausted as he was.

It was some time before either of them spoke, or moved.

“Can we eat now?” Sirius asked, his voice husky from exhaustion.

“How can you ever think about food?”

“Well, it’d be a shame to let it go to waste…”

Snape groaned.

“If you can move Black, be my guest.”

Sirius gingerly shifted, he wasn’t entirely sure which parts of his body ached the most. As he settled on the cushions, Snape clearly found his wand and cleaned up the mess of chocolate, cream and semen. Sirius was just about to tuck into the food, when the clock on the mantelpiece chimed. Sirius looked up.

“Hey look, it’s midnight Severus….Dammit”

Sirius shot up, ignoring the protest of his body, which definitely wasn’t happy with such sudden movement.

“Where the hell are you going Black?”

“Your present, I’ve got to give it to you before the clock finished chiming, otherwise it won’t be your birthday anymore”

Sirius dashed into the bedroom, grabbed the box he’d left sitting on the bedside table and hurried back to a slightly bemused looking Snape.

“Here!”

He thrust the box into Snape’s hands, just before the last chime of midnight.

“Open it”

Snape looked slightly suspicious.

“I promise, it’s nothing bad Severus”

“Why doesn’t that reassure me? Oh yes, because it’s from you”

Sirius attempted to look hurt by that comment, but he suspected that he was feeling too well-fucked to carry it off properly.

“Go on Sev…erus” he added, seeing the look on Snape’s face.

“Oh, very well”

Snape undid the ribbon, and carefully pulled off the paper. Inside was a box. He looked at Sirius, who was trying very hard not to look too excited. Snape opened the box. Inside was a silver key, on a long silver chain.

He looked at Black, and raised an eyebrow.

Sirius shrugged, and held up a pair of handcuffs and a collar with a lock.

Snape looked at the cuff and collar, then at Sirius. He looked at the meal laid out on the table. Then back at Sirius.

Sirius waited, a little nervous now. Then more so when that slightly wild light lit up Snape’s eyes again. Sirius just had time to brace himself before Snape launched himself and covered Sirius’ body with his once again.

He wondered how he was going to top this next year, because if this was the reaction, Sirius figured it was a tradition he would happily give up time to prepare…….
