Silent understanding
It's a blackcest oneshot. Sirius/Regulus.
Ao3
Now, being this close to him again after all these years feels natural, like falling into an old habit they never really unlearned.
"You will not believe," Regulus starts talking as soon as he's in the room, his voice sounds like he was running a second ago but it's still dramatic nonetheless. "What happened today."
Sirius jolts on his bed, almost dropping his phone on his face. "What the...Reg, do you know that knocking before walking into someone's room is still a thing?" He wants to sound like he's really annoyed but he feels his lips stretch into a light smile as he sits up a little to look at his brother properly.
They started talking again like a month ago and Sirius still feels as happy about it as on the first morning when Regulus actually initiated conversation and didn't try to insult him even once. He's giving this a chance. Walking into the room unannounced is a very recent development though.
"Oh, please," Regulus rolls his eyes as he walks towards the bed and crawls on it to face Sirius. "It's not like you ever do anything when I come over except listening to music and whatever it is you're doing on your phone." Regulus's cheeks are slightly pink and he looks less annoyed already. Since finishing school Sirius has been putting off any serious decisions regarding his future content with small jobs here and there. It's not like money is an issue for them.
Sirius gasps in a mock offence. "I could have had someone here, Reggie."
"Why would you..." When realization hits Regulus he makes a disgusted face that sends Sirius in a fit of laughter. "That's not funny!" Regulus is blushing How cute "Do it in our apartment and I'll kill you and your 'someone'."
"Dramatic much." Sirius is still grinning. He missed this. Regulus is glaring at him but there's no real malice in his eyes.
"I'm not being dramatic." Regulus scowls "I just know what boundaries and respect are."
This makes Sirius want to laugh again. "How does my sex life push your boundaries? You're the one walking into my room without knocking all the time."
Regulus looks like he wants to strangle him "So it would be fine with you if i...Forget it." He waves his hand in front of his face. "I hate you. I came here to tell you about school and now you're setting these disgusting images in my head."
Sirius gasps dramatically again. "There's nothing disgusting about my sex life. Ouch!" The moment he finishes this sentence he feels Regulus hitting him with his bag.
"You little brat." He catches his wrists trapping the bag between them as they wrestle. "First coming into my room unannounced." He doesn't really mind that much if he's being honest with himself but it's fun to rile up Regulus. He pushes him on his side with his body weight and throws his right leg over him. Regulus unsurprisingly puts up a fight, huffing and cursing him. His skinny figure does make Sirius forget sometimes that he's not actually weak. Just lean. Still weaker than him though so Sirius has no problems overpowering him. "And now insulting me." He straddles him squeezing his body with his legs. "Would you calm down already?" He raises his tone, getting annoyed when Regulus doesn't stop trying to twist his arms out of Sirius's hold.
"Would you let me go?" Regulus snarls back. He looks slightly disheveled, his hair is all over the pillow, cheeks pink and eyes are angry.
"So you can hit me again?" Sirius breathes faster from all the moving and lets go of Regulus's wrists when he feels his body relax under him.
They stare at each other for a few more moments. It should feel weird Sirius thinks. Sitting like this. But it isn't. Maybe it is for Regulus? Sirius observes his expression for any signs of unspoken discomfort but there's none. He just stares back like this fight isn't over for him but now he's trying to prove something without any physical force. Sirius shifts a little.
They were practically attached by the hip when they were kids. Regulus used to love to cuddle with him at night even though Sirius would tease him about it every time. Even then it was difficult for him to accept affection without deflecting it with jokes. Now, being this close to him again after all these years feels natural, like falling into an old habit they never really unlearned.
"So...What did you want to tell me?" If he wants me to fuck off he'll tell me Sirius decides. He doesn't want him to do it though for that he can admit. It's nice to have Regulus so close. He takes his bag and throws it carefully on the floor near the bed.
Regulus huffs and for a moment Sirius feels his heart jolt in fear that Regulus will tell him to fuck off. "Now that I've let off a steam a little, it doesn't feel as important." Regulus shrugs, averting his gaze from Sirius. The fight is over. His cheeks are still pink but Sirius can't tell if it's from all the wrestling or he's embarrassed of his position. "Barty melted a part of his table in chemistry class and the test was cancelled." Regulus's lips twitch. "I was preparing for this damn test so hard and I was so annoyed but now I remember Slughorn's face." He looks at Sirius again and they both laugh.
Sirius relaxes seeing his smile. "Barty received detentions until the end of semester and his parents will be informed cause someone has to pay for the damage." Regulus is giggling freely at this point and Sirius feels his heart squeeze "I don't think he minds it much. Might have done it on purpose, this fucker. I don't believe he's that stupid."
Sirius is laughing "I want to say i don't believe someone can be annoyed about a canceled test but since it's you it's not very surprising."
Regulus glares at him but it's more playful than anything. "Not everyone is as unconcerned about their education as you are."
"And not everyone still passed everything like i did" Sirius shoots back grinning cockily and falls on his side facing Regulus's profile. He rolls his eyes but doesn't say anything as he turns a little to face him.
They just lay like this. Sirius feels warm and sweaty after the mini fight and Regulus's uniform is all creased but he doesn't seem to mind it. He looks like he's deep in thoughts observing Sirius's face and Sirius just lets him.
"Don't." Regulus's voice is soft.
"Don't what?" Sirius frowns a little confused.
"Don't bring anyone here." Regulus looks him straight in the eyes and Sirius's heart skips a beat. He wants to make it into a joke. He wants to pretend he doesn't understand. He knows that Regulus will let him get away with it. But he doesn't.
"Okay."
"Okay?"
"Yes." Sirius says softly.
Regulus looks surprised for a moment, like he didn't expect Sirius to agree so easily but then he nods and gives him a small smile.
It's a silent understanding between them. There was always something there. Something too much, too close. None of them ever knew how to approach it.
They don't talk about it this time either.
Sirius chuckles and sits up a little leaning against a bed frame, Regulus's eyes trailing after him. Sirius looks at him and feels an urge to joke about him being a jealous freak. To tell him that he never brings anyone here. He stays silent and cocks one eyebrow when Regulus keeps staring at him.
Regulus sighs and moves his gaze to the ceiling. “I need to start preparing for my finals soon.” He says absentmindedly and Sirius hums.
“I'm sure you'll do fine.” He reassures “I don't see any reason to worry.”
“Hmm.” Regulus frowns and Sirius moves his hand to massage his head feeling the need to comfort him. Regulus relaxes after a moment melting under Sirius's touch. And Sirius, feeling brave, slips his fingers to his neck and collarbone.
Regulus shivers a little and Sirius feels a tug in his belly. He is so sensitive.
He doesn't say anything and Sirius doesn't prod either.
“I'm hungry.” Regulus grumbles sitting up after around 20 minutes of just laying like this. He sits up, shifting a little, and Sirius wants to look down and see if all this touching is affecting his brother like it affects him, but Regulus is already turning away.
No.
Sirius catches him by the arm and tugs him back. He doesn't give Regulus more than a second to react before his lips are on his.
I'm kissing him. I'm kissing Regulus. There's no ignoring this anymore.
Regulus's lips are surprisingly soft. With how much he bites them Sirius would expect them to be more chapped. Regulus freezes for a moment and Sirius fights the urge to pull away.
Warmth spreads in his stomach when Regulus kisses him back.
There's no need for words.
