MOST PRECIOUS TREASURE

Chapter 1

The sounds of harsh breathing could be heard around the empty classroom by the two occupants engaged in the most intimate of dance that bodies could perform. But the sounds that were filling the room fell into deaf ears, for the couple's attention were taken fully by one another; nothing else but their pleasure mattered. At this moment in time, they weren't Moony and Padfoot, fellow Marauders and best friends; they were simply Remus and Sirius and nothing else but each other exist.

Sirius could feel the pleasure building up inside of him, mounting into a peak until he came with a scream of Remus' name. Remus followed not long after and he dropped, boneless, into the body underneath his in exhaustion. Now that clarity was starting to return to him, he secretly cringed at the knowledge that he'd lost control and done it again.

He'd promised himself that their previous time was going to be the last; that he wouldn't use his beautiful friend this way, but his need was overpowering his common sense. Remus Lupin had always been known as the sensible and responsible one out of The Marauders, but he was proving himself wrong to these words right at this moment.

He would be lying to himself if he said that he didn't care for the man lying underneath him past platonic feelings, for he did. He'd been in love with the beautiful and loyal Black boy since their fourth year; two years ago. He held himself back and in-check in fear of ruining their friendship. Every time he felt like running his fingers through those soft ebony locks like what he was doing right at this moment, he fisted his hands until the pain stopped him from this urge. Every time he felt like kissing those pink lips, he bit his own to quell his want and whenever Sirius decided to change in front of him, he'd pinch himself hard to stay still in front of the show of those bare, ivory skins.

When they'd somehow started this...fling, Remus had been the one to decide that they couldn't come out and be seen as a couple. To his utter shock and amazement, Sirius had simply agreed; a hidden emotion that Remus couldn't fathom swirling in his silver orbs. He still couldn't get over the fact that Sirius had always been so obedient, so pliant to his will. It was so unlike the usual Sirius Black who was the cause of mischief and mayhem that befell Hogwarts throughout the years.

It was as if Sirius had shed all of his mask and pretenses in front of him -only him, he thought possessively- and in the place of the usual hot-headed loud Padfoot was a soft, enchantingly vulnerable Sirius. It was exhilarating, the power he seemed to hold over this beautiful creature. Not because of the fact that he would rule over the other boy, but because it showed just how much Sirius trusted him. He would, in return, make sure that every experience they had together would be nothing short of mind-blindingly gratifying for the other boy.

By this time, they knew their routine and what they had to do. They would silently dress, clean up any mess or evidences left behind and one of them, usually Sirius, would leave the room first to keep them inconspicuous. This time though, by the time Remus had finished dressing up, he found Sirius barely clothed; only managing to put on and buttoned up his white shirt halfway.

A sudden worry filled Remus. Had he been too rough? Is Sirius hurting? Did he somehow manage to do this without the other's consent?

This was one of the troubles Remus felt ever since he found Sirius with his other personality. Sirius seemed to never deny him anything; going along with anything the other boy suggested. Remus didn't know as to whether he had breached an invisible line or not; it was a constant worry to the werewolf.

"Sirius? Are you alright? Did I... Did I hurt you?"

Sirius lifted his head and shook it in reply.

"Then, why-"

"It's nothing, Remus. Just feeling a bit tired, that's all. You didn't hurt me, you were always gentle," replied the other with a small smile.

Remus silently breathed a sigh of relief.

"You want me to help you? Here," Remus bend himself to help the other boy dress and carefully buttoned up the white shirt the rest of the way, before taking Sirius' slacks that had managed to escape to the edge of the classroom.

He silently handed the black pants to Sirius, eyes involuntarily following the other's movement as he slowly put it on. Remus couldn't help but felt hot inside when he saw just how debauched Sirius looked; hair mussed and with only a shirt to cover the top of his long legs. He thanked Merlin about the fact that he was spent enough not to physically react to the view in front of him.

Sirius was somehow avoiding his eyes; looking down and giving his full concentration to the cloth in his hand. After he zipped and buttoned up his pants, he finally turned to Remus and asked,

"Remus, do you want to leave first?"

Remus shook his head in response and told Sirius to go ahead. Hesitantly, Sirius agreed.

"Okay. Thank you for waiting for me, Remus," managed the ebony-haired with a smile that was returned by the shorter boy.

Walking slowly but carefully avoiding any watching prefects or professors, Sirius arrived inside the Gryffindor common room not ten minutes after. He quickly climbed up into the Marauder's dorm room and found Peter asleep but James' bed was empty.

Probably having a rendezvous with Evans, thought Sirius with a smirk.

He quickly walked towards the direction of the bathroom; deciding to have a hot shower before sleeping.

When he stepped out of the bathroom, donned in his sleeping clothes, he found Remus reading a novel, seemingly waiting for him for a turn in the bathroom. They simply smiled at each other; acting as if nothing was out of the usual.

Back to friends again, Sirius thought with a heavy heart.

Every time they did this, the changing of attitude that they had to carry out had always lodged a pain in his heart. It was getting harder and harder for the dog animagus to pretend like nothing happened; like what they have was non-existent. He wanted so badly to stop this messed up relationship but he couldn't bring himself to do it; for he simply needed Remus like he needed the air and so he told himself time and time again to be grateful for all that he has.

He sighed and decided to sleep off the depressing thoughts. He climbed onto the dorm bed, closed the curtain around him and slid under the covers. It was nearing winter and the nights were becoming more chilly. Closing his eyes, he pictured himself and Remus being a couple, his happiness of being Remus' boyfriend, and fell into a slumber with a hopeful smile on his lips.

The next morning Sirius was woken up by James' loud curse . Blearily opening his eyes and opening the curtain, he was greeted by the sight of James hopping around on one foot and holding his other.

"Prongs? S'too freaking early fo' curses," complained the sleepy boy. James turned in his direction and glared; how he managed to do that and cringe at the same time remained a mystery.

"You try to stub your toe and not curse, it'll be impossible for someone with a mouth dirtier than mine."

Grumbling and muttering what was sure to be the prove of James' words, Sirius stepped out of his bed and went to get ready. He could see that Remus' bed was empty. This was unusual because Remus never liked mornings and was always the last to wake up with the exception of exam days.

"Remus already went?"

"Yeah. He had prefect's duty or something of the sort," answered James without looking at him.

"Oh."

When Sirius arrived in the Great Hall, he was able to see Remus sitting in their usual spot, but something was different that morning because he was not alone. Another girl that wasn't Lily was sitting next to him and they seemed to be deep in conversation.

"Morning, Moony!"

Remus turned and smiled at his three companions.

"Morning Sirius, James, Pete."

Sirius seated himself next to Remus while James placed himself in front of him.

After Remus introduced the girl next to him, they started on the breakfast. Sirius couldn't remember her name, but she was also a Gryffindor prefect who happened to be Remus' partner for their morning duties.

The rest of the day passed by peacefully without an incident and they were all on their way back towards the common room when Sirius realised that he'd left his DADA book at the classroom. He declined the others' offers to accompany him and promptly fell into a run to get the book quicker.

When he arrived at the classroom, he was surprised to see a silhouette of someone standing at the place where Sirius had sat earlier during the day. The person's back was faced towards him but he seemed familiar...

Coming closer he was surprised to find his cousin's fiancé standing with his book in his hand.

"Lucius? What are you doing here? And what are you doing with my book?"

Lucius turned at his voice and on his face was the usual malicious smirk that Sirius had learnt over the years to mean that the other was plotting something bad. Just my luck to have my nemesis' best friend with my book and only the two of us being here.

"Sirius, I see you came to find your lost book," the blond-haired boy stated in his usual haughty manner.

"Yes, and what of it?" Asked Sirius with a wary look on his face. He'd never liked Lucius but they were forced to act civil to one another due to the family ties. After Sirius ran away from his family home, the two were able to lash out their dislike towards each other more openly. Sirius liked it that way for he never liked to act civil to another person who he hated.

"Hmm, nothing. I'm actually just thinking of how empty this classroom is. Does it bring you memories of things?"

Sirius felt his blood run cold. He knew what the other was implying; it was clear from the way the smirk deepened on the other's feature. Lucius knew. Sirius didn't know how he could've found out, but he knew.

The raven-haired Marauder started to feel panicked, though his outer expression remained impassive, something that he was able to do due to the upbringing from his family. Sirius wasn't worried about himself; he was the subject of gossip all the time, and his reputation had never been the best, especially ever since he was disowned.

He was worried for Remus because the other boy had always been known as one of the best students in Hogwarts. Sirius was tainted in everything, but Remus, his dear Remy was pure. He had the heart of gold and kindness like no other. Sirius had no doubt that Lucius would be using this knowledge to his advantage in ruining Remus' reputation.

"I don't know what you're talking about. Speaking in riddles now, Lucius? Have you turned old suddenly?" Mocked Sirius with feigned ignorance.

Lucius snarled in ager before answering in a low voice, "Don't play coy with me, Black. You and I both know what I'm talking about. I heard you and that boy-toy of yours, you can't deny it."

"Remus is not my- he's not that! Don't you dare to ever call him that again!" Exclaimed Sirius vehemently before continuing, "And in case you forgot, I'm not a Black anymore. As for what you're saying, you have no proof, what makes you think people would it?"

Lucius released a malicious grin.

"Oh, but I don't necessarily need prove to spread a rumour, do I? And a rumour is all I need to ruin the reputation of that bookworm of yours."

Sirius narrowed his eyes. He knew what Lucius is saying was right, but he wouldn't give the other the pleasure of knowing that.

"What are you proposing here? You're not the type to speak to your enemy unnecessarily unless you're plotting something. You could've spread the rumour by now, so what do you want?"

Sirius was jolted into self-guard when he realised how Lucius' sneer turned lustful.

"It's simple. All I'm asking here is a barter. Silence from me for a... shall we say, a service from you in return," answered the blond male.

Sirius knew right away the kind of service that the other was asking for, and the thought made him want to vomit.

"You disgust me. How could you do that to Narcissa? She loves you, you imbecile! I may not care for my family, but that doesn't make it any less true," snarled Sirius with loathe in his voice.

"Yes, that's true. And I love her too. However, that is not to say that I wouldn't try a new experience of having the most popular male of Hogwarts writhing underneath me. I can assure you that you would have a pleasant time. All I need you to do is lie down obediently and spread your legs; not hard is it, considering it would be what you do with that brunet of yours in regular basis."

Sirius saw red. He couldn't stand it; his whole being was suddenly filled with the need to kill and destroy the boy standing in front of him. How dare he? He didn't know the pain he felt every single time he let Remus filled him, for he knew that his dream would never come true. But that didn't mean that he would do It for anyone else. Remus was special; he was the Sirius' only one.

"You bastard! Don't you dare ever-"

But Lucius merely chuckled in spiteful amusement despite the fact that Sirius was holding him up by his collar and was a step away from bashing up his face. The chuckle paused the other male from moving and that one second mistake was all it took for the Slytherin boy to reverse their position; pinning Sirius' body against the table and wand against his neck.

"Now, now, Sirius, don't be hasty. Why don't I set the time for tonight? Come to the top of the Astronomy tower at nine o'clock sharp. I do not tolerate lateness."

With those words, he released Sirius from his hold and the other was quick to straighten himself and also pull out his wand.

"I don't want to fight you. I only need you to please me tonight and I'll keep my silence. I've always wondered what it would be like to fuck another boy," Lucius stated in a mocking tone.

"And if I don't agree to your terms?"

"Well, then, perhaps I need to notch up my threat and tell you that I also know one other reason of that Lupin of yours. Funny that his name was reminiscent to his nature, don't you think?" With those words, Lucius walked out of the room.

Sirius couldn't believe what was happening. He couldn't believe how the other could have known about Remus' lycanthropy. He didn't know what to do. He knew he could never submit to the evil Slytherin git.

Even for Remus? His mind asked.

That was all it took for him to make his decision. Remus mattered more than anything; he could stand a humiliation for one night from the Slytherin bastard if it would mean Remus was safe and happy.

But what about yourself? His inner voice asked again.

I don't matter; my happiness is second to Remus'.
