Also not a lemon, just something I could not get out of my head and wrote out and so why not put it in here too?

Sirius always did everything with such life, but he rarely planned his next course of action, the impulsive lunatic. The two warring sides of his everyday life and causal results were the best headaches of Remus's life.

He never knew if Sirius was leaning in for a casual kiss, or if he was about to start something. Remus at least had the wherewithal to never try instigating if they didn't have the time planned out!

Padfoot leaned in for a parting kiss on the way to class, Remus casually kissed him back, and then Sirius reached out and tugged him back, palm clasping firmly down on the back of his neck to secure him in place as he deepened the kiss, the skin of his lips dancing against his encouraging him to play along, the firm flow of his jaw at an already practiced ease to keep him leaning in closer for more.

Willingly playing this up just for the rush he always got at kissing him but not yet willing to be late, he still pulled back when the tardy bell rang to pant, "Sirius-"

"I know, I know," his voice was too damn casual for the deserted corridor that already promised detention for both of them being late to class and being caught like this as he peppered kisses along his jaw, accentuating each word as his other hand tugged lightly where his shirt was tucked in. 

As if he were any better, he still had his hands wrapped casually around Sirius's waist with no idea when he'd leaned in to hold on. He should say something else, now, before this escalated-

Sirius's hand slid up, into his hair, twining into the locks and steering his mouth back and then his boyfriend's tongue was slipping into his mouth, and without the hustle of a crowd he somehow lost track of how Sirius was being pushed against the wall as they kept leaning into each other until Padfoot's hand left his waist to begin fidgeting for a door handle-

"Fuck," Remus laughed, ruining any context the curse should have held as Sirius grabbed his tie and started pulling him in with that addicting smile, Remus was already rolling his tongue around his vacant mouth with longing for the loss, hot and warm everywhere but where he should be in a classroom. "We should," he leaned in and kissed him, still tugging his waist closer to go back out he vaguely told himself, "get to the dorm," he finished in an unintelligible mutter all the same as he threaded the scarlet, silk material of his tie between his fingers to pin Sirius as close as possible without breaking the kiss, the hurried mismatch of flesh trying to speak and lust after each other was not as deterring as it should have been.

"Right, yeah, in a second," Sirius laughed and then slammed the door and Remus lost any thread of pretending this wasn't happening as he intentionally pushed Sirius against the wall while Padfoot hastily began untucking Moony's shirt.

It wasn't unexpected, the week after a full moon, but this was ridiculous, Remus kept scolding himself as he greedily kept his lover pinned, they'd just given each other a handjob last night mere hours after Remus had fucked him right after dinner, it must have been less than twelve hours since- he groaned in appreciation and gave the first small, gentle thrust forward as the rough skin of Sirius's palms met his marred flesh, Moony's shirt only half unbuttoned at the top, his tie had been discarded somewhere the cad, somehow Sirius was so pliable and yet firm as his fingers began gently flowing up taking the material with him, always stopping to press his fingerprints in at any random available scar and punctuating each somehow by making every next rove of his tongue more enthusiastic than the last.

Remus's hands started moving of their own violation from Padfoot's tie and unbuttoning his shirt to reciprocate as he kept giggly looking to the door that would slam into his elbow if it opened now, only getting a few of the stubborn things undone before switching back to the knot, fumbling to much to make any progress at either and Merlin why was Sirius so fast at this...

They were laughing to each other when it could go no higher and they had to break apart in the dark room, knowing exactly what was going to happen now and Remus just didn't care anymore as his shirt was discarded away because Sirius's silvery-gray eyes were the brightest thing in his life smiling up at him as one hand pressed into the small of his back to needlessly pull him right into the nonexistent space, he was already pressing himself as close as he could, fidgeting with the tie impatiently with one hand now and Padfoot was probably craning his neck uncomfortably to keep kissing him while the other went impatiently down and began creeping the button of Remus's trousers lose. Moony was suddenly impatient to have the most sensitive part of his boyfriend exposed too as he seemed content to play this up and keep messing with him now that he'd agreed, just gently rutting against each other. To much sugar from breakfast, he could still taste it on his Padfoot.

Sirius released a breathless noise, right on the edge of that barking laugh again as he won incredibly fast, he had no problems with that button and his boyfriend hadn't even put on a belt today, Remus's long fingers slipping through the material beneath to begin toying right back, his pants falling loosely away and his briefs were no hassle-

But then his back suddenly felt cold-

And Sirius was tense, his carefree lean against the wall gone, pushing him back-

Remus tried to get away in confusion, horror, stumbling over his feet and dreading what had he done now to hurt him-

Padfoot was moving him, steering him, the room was a whirl as he tried to understand what that bright light was-

It was freezing against the wall where he was now being crowded, skin littered with more goosebumps than silvery scars-

"What on Earth?" The voice finally made everything plateau back and Remus found himself scarlet and mortified for the unknown girl that was looking at the two of them. Her features were still blurring around the edges like he was still spinning, he felt like he was as he kept gasping and holding onto Sirius for the abrupt change. Apparently they'd been thrashing around more than he thought, somehow he was backed into the darkest part of the room far too fast compared to the stranger in the doorway. Her hair was a golden color, and she was clutching something silver in her hand- he gagged and leaned in closer to Padfoot now as he felt the little metal in the room she so casually held.

"Get out, now," the dangerous tone Sirius lashed out promised he would act on the threat it carried even as his arms didn't so much as twitch from their defensive posture he kept where both hands were now guarding him against the wall, palms flat against the stone, not a gust of air could get to him without it hitting Sirius first. Padfoot's hair was a disheveled-do from being tossed around, his shirt and tie hung in a hilarious half-done mess, and his pants sagged around his mid thighs, partially flashing the girl from being half-exposed thanks to his handiwork... but aside from his tomato red face and even being a few inches taller, the fellow student would not be able to see his scars.

The girl made a little tisk noise and clearly didn't need to be told twice, whatever she'd come in here for clearly no longer relevant as she let her necklace fall back to her chest and casually left, leaving the door open behind her. Rude.

"Shit Moony, I'm so sorry," Sirius finally dropped his arms and drew his wand, summoning his shirt and turning to him with absolute remorse as he handed it back. "Did not think that one through."

Remus took it in his numb hand and shrugged it back on still fighting off pathetic little trembles as the echo of adrenaline gave him the desire to do more than just stand here, it was as much a chore now to do up the buttons again as it was to take them off his boyfriend. Sirius only watched with a sad little smile until he got all the exposing flesh hidden back away like he was still expecting to be scolded any second as Remus casually flicked his tie across the back of his neck. "Can't hardly be mad when I was behaving no better now can I?" He asked with much more roguishness than he deserved for how incredibly not cool under pressure he was in comparison. He didn't bother doing up the tie, instead reached out and gently cupped Sirius's face with the one hand that had finally stopped spasming, the other hadn't quite managed it. "Thank you."

Sirius merely hummed and leaned into the touch, still looking up at him with the most wide, trusting eyes, and a jest on his lips. "Why do we call you the responsible one again?"

"I get caught the least," he needlessly reminded with a chuckle. 

"Ah, yes, then you're quite welcome," Sirius beamed, his hand covering his own and pressing it harder into the sharp cheekbone as he laced their fingers together.
