"Snape is stalking you."

Sirius almost choked on his eggs at his best mate's outburst.

"What are you on about James?"

"There. Look right there. He's staring at you!"

Sirius grimaced and lifted his head. Sitting at his usual spot with the younger years was Severus Snape, openly staring at him with an expression of horror and disgust.

"He's not staring at me James. Eat your breakfast."

James craned his neck for a better view. There was no doubt. Snape's eyes were practically burning into Sirius!

"He is too staring at you Sirius. Are you blind? Just look at him! He's been giving you that weird look since Friday!"

Sirius slammed his fork down on the table, making James jump in surprise. James' eyebrows shot up as he took in his best friend's appearance. Sirius looked frazzled. Expression bordering on madness and his usually well groomed hair sticking up at angles James found downright enviable.

"Sirius, mate, what's the matter with you? You've been acting odd for a week?! What on earth ha-"

"Idontwannatalkaboutsnapeanymore!"

James' eyebrows rose impossibly further up into his messy bangs, "Sorry. Didn't catch that."

Sirius cleared his throat, obviously trying to collect himself. When he spoke again he looked marginally saner, "James, I've been doing some thinking over the past week and have come to the conclusion Remus is right?"

"Remus is right?"

"Yes… about…. Snape. I thought about it and he's right, we should leave Snape alone."

James didn't even try to mask his disbelief, "Let me get this straight…. You have come to the conclusion. After some SERIOUS THOUGHT that we should leave Severus Snape, THAT Severus Snape, alone."

"James, James, James," Sirius clapped his friend on the back, desperately trying to shed the last of his nerves, "Enough about Snape. Who wants to talk about that greasy bas- err I mean guy anyway. Let's talk about more important things, How is Operation Tiger Lily coming along?"

Luckily James took the bait hook, line, and sinker, launching into a lecture about his recent adventures in Lily-Evans-Seduction. Having spent the last six years hearing about such activities Sirius felt no guilt tuning out, stealing glances to the disgusted Slytherin across the hall.

Snape was so ugly! Why did he ever fuck such a scrawny, beaky, greasy… BOY! There was no way he'd ever admit to such depravity! What the fuck was he even thinking? And as much as he wanted to spill about the new dirt he had on Snivelly there was no way he could tell James Snape was gay without divulging how he knew.

Not to mention he was so fucking sick of those looks. Everywhere he went Snape was there giving him such obvious glances. Did he WANT everyone to know they had fucked?

He looked up from his breakfast at the black eyes boring into him and took a violent bite out of his toast.

No matter what it took he would stop all of Snape's stupid glances and make sure his mouth stayed shut.

Snape clutched the piece of parchment in his hands. Enough was enough. Black had dropped it into his bag during Herbology. It only had a few words.

"Empty Classroom 5th Floor. Next to Bertrand the Barmy Statue. 7:00, We settle this tonight."

How ominous. Why did Gryffindors make everything so melodramatic? But despite how he despised the tendencies of Gryffindor house here he was, climbing the stairs to the room. What a nightmare. Black was… cringe… right. This needed to be settled, ideally in a way that spared Severus' remaining dignity.

Mulciber and Avery had already commented on Severus' odd behavior, noting how on edge he was recently. It was completely unacceptable. He couldn't afford for the truth about his sexuality to be leaked. The fallout would be catastrophic.

He opened the door to the classroom and Black was waiting for him. Leaning against a wall muttering to himself. Black jumped at his entrance and Snape smirked. Good. At least Black was as rattled as he was. Maybe this way he'd get everything he wanted.

"Black."

"Snape."

The two boys looked at each other in awkward silence before Snape broke it to issue his demands.

"We never speak of this again. Agreed?"

Black twitched in the corner nodding vigorously "I er- yes. Agreed!"

"You don't tell anyone I'm gay. I don't tell anyone you fucked me. Agreed?"

"Agreed."

The two teens looked at each other awkwardly. Snape exhaled a sigh of relief. This was about a thousand times easier than expected. Latching on to his defense mechanism of proper decorum he stepped forward, extending a hand.

"Good. Let's shake on it."

Sirius relaxed grabbing the hand and shaking it firmly. The two boys stared into each other's eyes. Fighting for dominance of the handshake, each trying to be the one to squeeze the hardest.

Snape felt Black step forward. Grip crushing his hand but wouldn't back down. Even as he felt the blush creep up his neck. Even as he felt Black's breath warm on his face. Even as he felt himself harden against Black's thigh, bodies pressed so close together…

A month ago Severus Snape would have believed it impossible to intimately know a desk.

"Hello again Snivelly."

He was sure every detail was branded into his memory.

"Turn around for me like a good little girl."

The face of the wood unevenly sanded.

"You're as pretty as a girl from behind Snivellus. But you should really wash your hair. Grease is unbecoming."

The sloppy stain job with blotches of dark and light.

"What's that Snivellus. You like it when I touch your hair like this?"

The map of scratches on its surface.

"You like it when I drag my nails down your back and smack your scrawny ass."

And its crown jewel, the odd pattern of the grain on the left most part, its shape an uncanny resemblance to Wales.

"I think you want something else though Snape. That's why you always come back here. So tell me."

No. There was no way he could face the sight of this old desk every day.

"Tell me Snape."

There was no way he could ever see this desk without thinking about this.

"Tell me exactly what you want."

And getting rock fucking hard.

"Tell me what you want and I'll give it to you."

And hating himself for it.

"I want you to fuck me."

Sirius groaned. Hearing those words from Snape never failed to send a spark of arousal straight through him. It was insane. This whole situation was insane. But here they were, meeting every Friday night in this classroom. Sirius greeted by the belligerent Slytherin bent over a desk in the corner, body begging to be fucked. After almost a month it had become routine, expected even. And he couldn't complain.

"Say it again."

Sirius had waited for something like this for years (even if he never expected sex to be involved). He had finally discovered how to get Snape to shut the fuck up. With a cock in his ass Snape tended to say very little, and when he did he never came out on top.

"I already told you exactly what I want Black so get to the fucking or I'm g-"

Sirius brought his hand down on the small pale cheeks in front of him, a loud smack and Snape's yelp ringing through the room. He caressed the red handprint left behind, hand occasionally drifting to stroke Snape's hole. But when he spoke, his voice was anything but gentle.

"Say it again Snape. Tell me what you fucking want. Tell me why you come down here every week. I want to hear you beg for it."

Sirius looked down at Snape and cringed. Half naked the boy looked even more pathetic than he usually did. Legs thin as twigs, hipbones and ribs jutting out. Nevertheless Sirius continued his ministrations. Aesthetics were never a motivator to begin with.

Adding more lube to his slickened fingers he pressed in, searching for Snape's prostate. When he felt Snape's knees buckle against the desk Sirius grinned before stilling completely.

"All you have to do is say it. Tell me what you want."

Sirius' fingers hovered, so close to the place that provided Snape such pleasure, their very presence teasing and coaxing Snape into further submission.

Severus whimpered and pushed his hips back desperate for friction.

"Tell me."

"Fine!" Severus cried out, "Fine. I want you to fuck me."

"What's the magic word?"

Even with Snape's angry sputtering, it never took long to get the answer. Just a few more teasing strokes and…

"Please fuck me Black. Please I want you to fuck me."

Satisfied Sirius withdrew his hand and pressed forward. Plunging his cock deep and unmercifully into Snape's begging hole. Severus cried out at the intrusion but rocked his hips back to meet Black. Wanting it all.

Sirius and Severus began to move together, bodies fighting for dominance. Noting Snape's feeble attempts to be the one doing the fucking, Black grabbed his hips and thrust.

"You love this don't you faggot."

"I'm a faggot huh?" Snape looked back, face incredulous, "Tell me Black, if I'm a faggot what does that make you?"

Black sneered and pressed Snape's face into the desk once more. Leave it to Snape to sound condescending even in this position, "Very, very, charitable."

Black quickened his pace and all Severus could manage was a moan. His open lips pressed into the grooves of the desk. Moving across the ridges with every thrust. He tried to maneuver a hand to stroke himself, but the angle of Black's assault made it impossible to reach.

"Black, let me-" Sirius grabbed both of Snape's wrists and pinned them to the table.

Snape's body seized, but couldn't move. Black's large calloused hands restraining Snape's thin wrists like shackles.

"You want to touch yourself Snivelly? You want to stroke? You want to cum? I'll let you cum Snape, but if you want to cum you'll have to do it like a girl. From your hole."

"I'm not a fucking girl!" Snape's protests were useless. Arms still restrained he could do little but focus on the intense sensation of Black's cock rocking against his prostate, and the pleasure mounting with every thrust.

"Do it Snape. Cum for me. Cum like the girl you are."

Severus could feel tears prickling behind his eyes. Frustrated by the pleasure and humiliation he was powerless to stop. He felt the pressure growing until it was all too much and he released. Spilling onto the desk in waves as his orgasm throbbed through his body.

Feeling Snape cum beneath him was always enough to send him over the edge. Reaching the pinnacle of power over his enemy was the most satisfying feeling imaginable. Sirius released as well, filling Snape with his warm seed.

The final act of their little ritual completed, Sirius withdrew, zipping up his slacks and fixing his disheveled tie and hair.

Snape panted from his place on the desk, notably slower and shakier when doing up his own trousers.

"I'm not a fucking girl Black."

Sirius looked at his nemesis and couldn't help but smile. To think that shaky pathetic slut could have ever gotten under his skin. Not even deigning the statement with a response he left, a spring in his step.

Severus shook with rage in the empty classroom. How dare Black act so bloody superior! It was unacceptable. There was no way this could continue if Black was going to keep treating him this way. True this was probably the only sex he'd ever manage to get, but how was it worthwhile if in exchange he had to sacrifice his dignity?

Severus looked at the desk, white fluid welling in the grooves and dripping onto the floor. He banished it furiously, his temper managing to remove the left leg of the desk as well. It crashed onto the floor with a loud bang. Severus couldn't be bothered to right it instead opting to return to his dorm.

If this were to continue, he WOULD start getting something out of it.

"Tell me what you want Snape."

Another week, another round of Sirius Black's warm breath in his ear. But today was a different day, and this time Snape knew exactly what he wanted.

"I want you to kiss me."

The hands roaming his sides let go, and Sirius Black jumped back, eyeing Snape with disbelief.

"What?"

Snape turned around and leaned against the wall. He had made up his mind. There would be no more of this impersonal demeaning fucking. If this were to continue, he would get something out of it.

"Are you deaf Black? I said I want you to kiss me."

Sirius couldn't help it. He laughed out loud. What was Snape playing at? He doubted Snape could be kissed with that great honking nose in the way. And besides,

"I'm not gay."

Severus raised an eyebrow. He really needed to stop overestimating Black's intelligence.

"Don't give me that fucking look Snape!" Black felt his cheeks redden against his will, cursing himself as he shrunk away from the accusation. "I'm not gay!"

"What a compelling argument. Certainly your cock in my ass every week is negligible as evidence. No one could possibly postulate you like men from such a thing."

"Funny Snape. I think that's the first time I've heard you use your big words to say something intelligent. I don't like men. And I certainly don't like you."

"Well it doesn't matter either way. If you wish to continue with these little…. trysts… I want something more out of the arrangement."

Sirius narrowed his eyes at Snape, maintaining his safe distance. "What more could you possibly want?"

Snape crowded Black to the wall, eyeing him like a lion sizing up dinner. "I want you to kiss me."

Black cringed. Snape was certainly a… sight to behold. How he had this much bloody confidence was one of the great mysteries of life. Thin as a rail, Lank greasy hair, and the way his tongue kept darting out to lick those overly chapped lips, exposing a line of crooked teeth as his mouth opened, it made him shudder.

Not to mention his hygiene, bigoted opinions, political affiliations, and personality all left much to be desired. Oh and he was male. That too.

Snape should be thankful he was even being fucked! Not making demands. Kiss him. As if Sirius would ever, ever, ever even consider such a thing!

"Now, now, Black. I'm not asking for the moon, just a kiss. Just one kiss and you can bend me over that desk and do what you please."

And that's when Black saw it. The briefest flash of insecurity. He had deflowered enough virgins to know the signs. So Snape felt vulnerable? This he could use.

The corners of Sirius' lips turned up into a small smile. Severus did not know what to make of a smiling Black and he certainly didn't know what to make of Black's hands wrapping around his waist pulling him close.

"Just a kiss Snape?"

Severus cursed himself for blushing, but it was difficult not to, especially when Black lifted his chin and started running the pad of his thumb over Severus' bottom lip. He was only a few inches shorter than Black, he could easily look him in the eye, but the sensuous touches made him feel impossibly small.

"I- er- yes?"

Severus whimpered as Sirius dragged his thumb down. Tracing a line from Severus' lip to his chin to his Adam's Apple until firmly grasping his neck, forcing Severus' face up. Severus hated how the pressure made him feel so defenseless. And hated how much he liked it.

"You want a kiss then?"

Severus bit his lip and nodded. Whimpering as Black's thumb pressed into his jaw with the slight bobbing of his head. Sirius' face was so close. He wanted it so badly. He hated how even after losing his virginity he had still never been kissed. All this humiliation would certainly be worth reaching such a milestone. And despite Black's despicable character, there was no denying the sensations he gave were downright addictive.

"If you want me to kiss you Snape you have to do something for me first."

Black maintained his grip on Snape's delicate neck, and moved his free hand to wrap around Snape's wrist. He manipulated the arm until Snape's hand was where he needed it to be. Rubbing the front of his slacks. He sighed at the sensation getting harder at the touch.

"Suck my cock Snape. Suck my cock and I'll kiss you all night long."

Snape felt the hard outline of Black's cock and he moaned. He couldn't deny he was curious. After all he had never been given the chance to see it properly. And if in exchange he'd be given a kiss…

He eyed Black suspiciously. "If I do this you'll kiss me."

"Of course."

"You swear."

"I swear."

After some deliberation curiosity won over his apprehension. And Snape agreed with another nod of his head.

Black released his neck and wrist. Dropping his slacks and pants before settling into the ornate chair behind the teacher's desk. He smirked and stroked his cock. "Alright Snape, get to it."

Severus was shaking with nerves as he lowered himself in front of Black, the flagstones uncomfortably hard on his knees. He looked up. Black looked like a mad king sitting on his throne, the medieval style of the room and chair doing nothing to improve the image.

He swallowed his nerves and appraised Black. It was bigger than he anticipated, much bigger than his own. Thick and dripping with precum. He was unsure how he had ever fit such a thing inside him. With a trembling hand he reached out and began to touch. His first stroke rewarded with a throaty, "Fuck yes."

Gaining more confidence with Black's vocalization he gripped harder, moving up and down on the shaft in a similar motion he used with his own masturbating. Using the chance to stroke Black's inner thigh with his other hand. He would never admit how much Black's body turned him on, especially the thighs, so thick and firm with a spattering of dark hair. It seemed Quidditch was good for something, balancing on a broomstick must really work the legs.

He felt compelled, bringing his head forward and licking and sucking the soft skin of Black's inner thigh. Moving higher and higher until his nose was buried in the crease of his leg. Nuzzling and licking the sensitive skin and dark curls.

Black bucked his hips at the sensation "Tease."

Fed up with the explorative touches, he grabbed Snape by the hair. Forcing him up to the head of his cock. "Suck it Snape. Suck it like a slut."

Severus was irked by the comment and pushy attitude, but decided to let it slide. Looking up at Black through hooded eyes before licking the droplet of precum from the head.

Sirius shuddered and pressed down, feeling Snape's mouth engulf his cock. "No biting," he growled. Forcing Snape's head down over the hardness, loving the tight wet heat.

Snape gagged, saliva filling his mouth and spilling over Black's cock. Sirius fucked his mouth unconcerned with Snape's comfort. Snape was no longer enjoying the act. Choking on spit and cock as he struggled to breathe. Yet he tried to endure, the promise of his first kiss a decent motivator.

"Suck my cock slut." Sirius loved the feeling. The power over Snape overwhelming as he thrust into Snape's throat over and over again. Feeling the tightness constrict with Snape's gagging and seeing the utter helplessness on Snape's stupid face. It was all so overwhelming. He came hard down Snape's throat, making him swallow wave after wave.

Snape thought it couldn't get any worse, but the salty bitter fluid pouring past his lips was extremely unpleasant. He struggled to swallow. The warm cum dribbling out of his mouth and down his chin.

Sirius withdrew, watching Snape sputter and cough, spitting cum over his silver and green tie. The sight stirring his spent cock.

Severus looked up, lips and chin still glistening with white. "There Black I sucked your fucking cock. Now it's time for your part of the bargain."

Sirius chuckled as he did up his slacks. And walked to the door. "I'm not going to kiss you Snape and I'm not going to fuck you."

Snape shot up, walking over to Black and shoving him hard. "What the fuck do you mean you aren't going to kiss me?!"

Sirius looked down, still smiling with the evil glint in his eye. "Take this as a lesson Snape. You think you can make demands? You think you can make me do shit for you? You think you have any power in this little… thing we have going on? Think again. You have nothing. You are nothing."

Snape could do nothing but open and close his mouth stupidly. Completely furious he had been had.

"See you next week girl." And with that Sirius stalked out of the room without a backwards glance.

The first Hogsmeade weekend of the year arrived with the second Saturday of October. Still furious with the events of the night before, Severus felt little desire to go. Sirius Black's stunt had turned him off of anything involving socialization. He wanted to stay behind, maybe do some brewing, but Avery and Mulciber were very insistent. They wanted him to be the pack mule while they picked some things up in the village, and Malfoy was coming down to meet them all for a drink.

The first stop was of course Honeydukes. Severus face contorted into a permanent frown while being pushed and shoved by the sweaty children and teens surrounding him. Avery, Mulciber, Rosier and Macnair filling his arms with more sweets than he could ever hope to eat, let alone afford.

Tipping the load onto the counter for the clerk to ring up, he looked around the shop. What he saw next caused his blood to boil. There, over by the cockroach clusters was Sirius fucking Black, kissing Marlene McKinnon soundly in the middle of Honeydukes. He began to shake with rage until a hand on his shoulder brought him back to the present.

"What do you want?!"

"Oi, calm the fuck down Snape, I was just asking if you were getting anything."

When he felt calm enough to answer, Snape spotted the truffle boxes next to the cashier. An evil grin spread over his face.

"Now that you mention it Mulciber, I do believe I will get something."

He was suddenly much more excited for Friday.
