They had done it. He hadn't meant to, he had just asked him and it happened. Remus couldn't remember how it had started.
He was in his dorm, waiting for James to come back from his Quidditch practice when he heard the door to their dormitory open then close. He swiftly opened his curtains, expecting to see his best friend standing in their doorway with a big smile, waiting to tell Remus all about that days Quidditch practice. Instead he saw the one person he hated and loved the most.
Sirius Orion Black. Sirius had betrayed him in the worst possible way. He had told Remus' enemy about his most secret and dangerous secret.
Remus Lupin was a werewolf.
In late December of summer of 1975, Sirius had broken all bonds he had with his friends. All the love he had gotten from everyone at school. The brotherhood of his best friend, james. The parental and not so unconditional love of his ec soon to be parents. But most of all, he had lost the love of his soulmate, Remus.
All these thoughts and many more rushed through Remus' head when he saw Sirius enter their dorm. He was in no shirt with his ugliest pair of trousers that Remus had ever seen him wear. But what caught remus' eye most of all was that Sirius was wet. He was soaked to the bone. Remus didn't know how this could be possible. It was late winter so the lake was frozen, it wasn't raining, and he had no remaining fronds to play water balloons with. How on earth has he gotten so wet? But none of that mattered. All that mattered was that Remus' ex lover was standing, half naked, soaking wet, looking gorgeous only for Remus to see.
As soon as Sirius saw Remus with the curtains open his eyes widened and he started stammering an apology. All the words he said about forgetting a towel before taking a shower in the prefect bathroom, about how he was sorry and that he didn't know Remus was in there flowed in one ear and out the other to remus.
The only thought that was going through his head was how hot Sirius looked. His pale white skin was in stark contrast with his dark hair and silver eyes. Eyes that had once been the center of Remus' universe, but now was the color he saw in his nightmares.
"I want to fuck you." Remus said. he didn't know where it came from, well obviously from him but he never meant to say it out loud.
"I'm sorry, what?" Sirius practically screeched, his face turning red a big difference between what he saw now and what he saw when sirius first spotted remus. The only difference between there and now was that instead of fear and regret that he had first seen was replaced by a want so hidden, that you would have to know those beautiful eyes so well to be able to reach it.
“You heard me.” Remus said, his voice a lot less shy now and more confident and demanding. “I have recently been very unhappy with the sex that I have been receiving from the supposed best bedders in Hogwarts so I thought I might as well ask you. I mean you were the best sex I have ever had. Well second to Edie Cartman from last year.”
Sirius’s face looked like he had receiver christmas and a fright at the same time. His look of wanting grew more and more prominent with each word that Remus spoke. “Wait- i thought that you weren't talking to me,” Sirius said this just above a whisper, his eyes cast to the ground and a glint of sadness in his gray orbs.
Remus not so casually took a step towards Sirius and lifted his chin up so that his face was less than an inch from his. “Well i was, but then i remember that before we dated we were fuck buddies. I thought, why not re open that so that both of our needs were met.”
Sirius slowly let his eyes meet Remus’ blue ones, ones that were filled with seductiveness, malice, and a little bit of hope. The only thought that was running through Sirius’ wind was one, hopeful and sad statement I think he is starting to forgive me.
Remus could see this hope of forgiveness start to spread throughout sirius’ face, spreading all the way from his eyes, that glissed with want and desire, to his lips that were filled with a small smile that obviously contained much more joy that he would like to admit. “Yeah ok that sounds good to me. Buti have to ask, are there any rules?” He hoped the answer was no.
“Since when have you ever followed rules?”
“Since you started to be the one who made them.
There it was, Remus thought. The flirty banter he had missed. This felt like a chunk of his heart that had been starting to reseal be torn from him and shattered all over the ground.
As soon as Remus had uttered those last words, he put his mouth on Sirius’ as firmly and as casually as he could muster. Even though he tried to keep it casual, they couldn't help falling back into their old routines, they had kissed so much that it felt like second nature to them. The feel of remus’ lounge penetrating Sirius’ mouth and the feel of it on the top of Sirius’ tongue was almost enough to bring both of them to tears. Oh how they both had missed this.
“Skip the sex scene”
As they both came down from their high, absolute euphoria was rushing through Sirius’ mind. He had just had sex with his ex lover, who he still very much loved and adored. Meanwhile, all that was rushing through remus’ mind was what James was going to think when he returned any minute.
Remus, forgetting to put on any clothes, had swiftly gotten up and instructed Sirius to do the same. He quickly rushed Sirius to the bathroom and told him to take a shower and that James would be back soon.
The last thing that remus saw was the face of Sirius Black when he realized that Remus had not in fact had any plan on forgiving him or of telling any of his friends about this. HIs face so heart broken but with a tinge of hope still left that Remus almost felt bad for him, but remus couldn't think about that now, he just had to think about the damage he had just caused.
