I'm sorry I've taken so long to write this! I just haven't had time to write recently since school started.

Enjoy! This is probably the last chapter…

------------------------------------------------------------------------------------------------

Severus waited until all the students and professors were out of sight, chasing down Sirius Black, before he stood to return to the castle. He brushed off the light snow and strode indoors before someone found him.

He stayed to the shadows; he didn't want to get caught for the 'fight' he had with Black. Even if he did, he could just pin the blame on Sirius like he always did when Black and his friends were up to something. Snape the snitch, he was, always getting them into trouble. In return he was hexed and embarrassed...

Severus stopped his thought process and instead switched to Sirius. What was going on now? They both established that they wanted each other, now what? Were they - a couple? No, guys weren't really couples, they were more like - lovers. He was Black's lover. That sounded funny. I'm Black's lover. Ugh. Well, if that's what it was, fine. They would just have to deal with the other's tantrums. But he didn't really have temper tantrums, right?

Snape found himself down a deserted corridor, stopping to look outside. The Headmaster was dragging along lump behind him, kicking to be released. Sirius swung his head back to see Severus snickering at him. He glared back. Dumbledore spotted Severus, dragging Sirius towards him. He dropped Sirius who swiftly jumped up to stand beside Severus. Dumbledore stared at them both.

"Severus, I trust that you can lead Mr. Black here to my office while I take of some business. I should meet you two there within the hour. Yes, Severus, I wish to speak to you as well. I am quite shocked at you."

"Of course, Headmaster," Severus replied.

"Wait! This isn't any of his fault -"

"Enough, Mr. Black. Now get moving."

Dumbledore swung around and took off down the other way, leaving the two boys standing together in silence.

Sirius stared at Severus who avoided his eyes before speaking.

"Very well then, mate. But knowing him, he's going to be a long time till he speaks with us," Black muttered. He glanced back out into the snow. When he looked back, Severus was already moving.

"We're not actually going to go to his office are we?"

"Yes."

"All right then. I suppose we can make the best of it," Sirius declared as he followed Severus.

Snape watched the floor as they walked side by side, then realized that other students still hebetated this castle. He sped up to be a few feet in front of Black as they approached the staircases.

"Hey," Black caught him by the sleeve, pulling him to a stop.

Snape pulled away, glancing over at the wall, before he had enough gut to look Black in the eye. "Do you mind if we get to the office first?"

"Ok..."

Coming to Dumbledore's door, Sirius muttered, "Fizzing Whizbees," smiling back at Snape when the door opened. "I come here enough, I should know."

Severus was hesitant as Sirius took the first step. "Perhaps we should wait for him -"

"Yes, we'll wait in his office. C'mon. It was your idea." Sirius disappeared up the staircase.

"I was only obeying… fine."

Perhaps Severus was hesitant because he knew what was coming. "Screw it," he whispered to himself, and followed Sirius up.

-----

Black reclined in one of Dumbledore's chairs as Severus wandered around, observing the headmaster's various gadgets and assorted nonsense on his shelves. He recognized all the strange substances and wondered if he could make off with some of them. Of course he really didn't need any of his materials. He had quite the stash under his bed.

As he made his way around the large office, he could feel Black watching him. Severus glanced at him from the corner of his eye. Sirius smiled. Bloody hell. He continued around, once touching Fawkes' soft feathers. The bird continued to sleep soundly. He eventually made it to the other side of the room and pulled a book from the shelf.

Suddenly he was pulled back and embraced by Black. Sirius took him down to the floor. Severus' book fell from his grip as he collapsed atop Sirius. He scrambled to get up but Black flipped them over and skillfully pinned him to the hard stone.

"What the bloody hell do you think you're doing, Black?" Severus propped himself on his elbows, glaring at Sirius who began to unbutton his shirt.

"I'm going to fuck you, Severus." His eyes glimmered and his hair fell from behind his ears to shadow his face.

Again? Severus sighed. He watched Sirius remove his shirt, hoping that Dumbledore would take a very long time doing whatever he was doing right now. Sirius bent over him, fingering Severus' robes before taking him in a deep kiss, running a hand to Severus' crotch. Skillfully, he ripped down Severus' pants, throwing aside his robes, never once being fought against.

"It seems that you actually want me to do this, Snape."

"I'd rather you not talk." He lay back and gripped Sirius' shoulders.

Black bent forward again and drew blood from a hard bite to Severus' neck. He licked his way down Severus' chest to his abdomen to his pelvis and finally pulled down Severus' shorts in which was contained a very hard erection.

"I didn't think it'd take so short," he muttered into Severus' flesh. Sirius stretched back up to kiss him, pressing himself against the other. Cupping Severus' face with one hand, he undid his pants with the other. Slipping them off, Sirius pressed his entire body to the other's, causing Severus to shutter slightly beneath him. Sirius bit his neck, lapping up a small amount of blood. Severus grimaced as he bit the other side, sliding both hands down to his waist. Sirius returned to his lips roughly, sliding his hands down further to his thighs. He lifted himself up slightly to reach under Severus' legs and pull them up.

Sirius had long since been hard and wanted Severus now. He took him without words and without a fight. He still wondered why Severus would let him to this so willingly. They had always hated each other… But there was no use asking himself anymore. They had done this before and they were doing it again. And it was beautiful.

Severus let Sirius pound into him, digging his nails into the other's arms, biting his own lip. It felt so good.

-----

For the next hour, Dumbledore was still somewhere else in the castle and the two took turns around the office with each other. Their eyes glowed in continual anticipation and passion. Silencio charms worked perfectly until the office door opened.

Sirius was lying head down on one of the big office chairs, Severus sprawled atop him, feet dangling off the top of the chair. They were in the midst of severe groping and licking when they both heard a cough. At once, they fell from the chair into a pile of limbs, scrambling up to face their intruder.

Naturally, it was the Headmaster, completely agape at the two boys in their birthday suits, and at the stained chair. Severus flushed immediately, his body temperature rose even higher than it had been with Sirius.

Sirius stepped forward to wave at the Headmaster. "Professor Dumbledore, Sir. We were waiting for you."

Severus scrambled to find his clothing as Black stood proudly before Dumbledore. How embarrassing. And Black, completely comfortable, as if nothing had happened. This would be the end of it.

"Ahhem, well, Black, Severus, if you would please clothe yourselves, I will return in a few minutes" He swiftly departed without another word.

The instant the Headmaster left the room, Severus took a swinging punch to Black's nose, knocking him backwards and pinning him to the floor. His face inches from the other's, he seethed as he tried to punch him again. Black stopped his wrists mid-air, trying to calm him down. Severus pulled away, standing back up to gather his clothing. Sirius lay on the floor, his nose bleeding slightly as he watched the other dress. He dared not say anything.

When Severus finished, he looked back down at the still-naked Sirius Black. "Don't ever touch me again, Black."

Sirius was about to respond when Dumbledore entered again. Seeing Sirius on the floor, he shook his head and approached anyway.

"I am very disappointed into you both. Especially you, Severus." He took to his desk and pet Fawkes as he spoke. "Black, would you please stand… Thank you. The fight in the grounds in excusable. I understand that you loathe each other. What you do n your private lives is none of my business. But neither of you will touch the other again, do you understand?

"Professor -" Severus started. He didn't have anything to say. He shook his head and bowed. "Understood."

"Understood…" muttered Sirius.

"Good. Sirius get dressed and I want both of you out of my office. I have business."

Severus swept out of the office without a glance to Sirius. He kept his eyes to the floor as he stumbled back to his common room. He felt an ache in a place where he hadn't felt anything in so long. He wasn't about to convince himself that everything would be ok. This was it. The headmaster had caught them shagging in his office. It was Sirius' fault. Not his. He didn't want this to begin with anyway, right? It wouldn't happen again. Anywhere.

-----

Severus woke up the next morning with a head cold. His pillow was moist and his nose stuffy. A quick spell would clear that right up.

He saw Sirius Black at breakfast. He ignored him and went on with his day. Sirius never came to find him. He was probably with his Gryffindor friends anyway…

That night, Severus was outdoors standing at the edge of the lake. No one was around luckily. He had never stood by the water's edge before. It was calming. It took him all day to empty his mind of yesterday's events. While he was still angry, he was more angry at himself than he was at Sirius.

"Severus," a voice whispered.

He looked around in the darkness until he spotted Black hunched behind the tree. "What do you want?"

Sirius approached him, hands in pockets, scarf tight about his neck. He stopped a yard away and caught Severus' eyes. "I want to apologize."

"Too late."

"Don't be so stubborn."

"I'm not."

"I'm sorry. I should've kept my hands off you."

"Yes, you should've. And you're not going to get another chance now, Black. Stay away from me." He turned on his heel and started back up towards the castle.

"Severus…please."

He stopped and glanced back at Black. He shouldn't be doing this. But it was something in his voice.

He waited.

Sirius finally realized that Severus was waiting for him. He came to stand before him and took his hands from his pockets to caress his cheeks. "I am sorry, Severus. I'm done playing with you." He kissed him warmly until Snape pulled away. He took Black's hand and led him back up to the castle.

Severus couldn't quite comprehend why he was doing what he did. He was humiliated yesterday. And here he was, taking Sirius like a puppy back to his common room. All he did realize was that he was quite possibly in love with this Gryffindor. A horrific act that goes against all laws of nature. He looked back once as they walked together and noticed Sirius' faint smile. He squeezed his hand. Perhaps he'd let Sirius into his dark corner of the library again one day.

(A/n) so the ending was a little fluffy. eh.
