CONTENT: mentions of blood + murder - not explicit, NSFW, bit of smut, mildly dark fic 18+, possessiveness
NOTES: You mfs are WILD! Anyway, don't kill anyone and don't romanticize real life murders or you're just... ew. Also, this goes without saying, but avoid this if it makes you uncomfortable.
Large spots of dark red were stained onto Sirius' white t-shirt that now lay on his bathroom floor.
Look, it wasn't Sirius' fault that he had killed that piece of shit. He just wouldn't stop talking to her; his hands trailing up and down her arm when she clearly didn't want it. If anything, he had done the world a favour.
Sirius needed less than a second before he decided: he needed to kill him.
Mad he might be, but man-men cannot plan; not the way he had the week leading up to the man’s death — sneaking into his house and held the bedcovers tightly against his neck, knife strapped to his side and ready to use.
He made sure to stage it as a robbery gone wrong.
With his alibi covered, evidence destroyed, bleached used to scrub away any possible fingerprints, Sirius headed home and immediately hopped in the shower. The smell of tangy iron and red water cascaded down his body before turning crystal clear. The hot puffs of air and smell vanished into the air vents above.
"Sirius! I'm home!" Her sweet voice rang out as the door clicked shut. He didn’t expect her to return that early. "Where are you?"
"Hi, love!" Sirius shouted back. In a panic, he popped out of the shower, picked up his bloodied clothes and tossed them into the nearby laundry basket — hiding them underneath the rest of the dirty clothes. "I'm in the bathroom!"
Quickly, he slipped back into the shower.
The bathroom door opened. He let out a breath. That was too close — his angel — his best girl seeing his tattered clothes.
Because no, no, no no no — he couldn’t scare her away. He wouldn’t.
"Work was awful," she muttered, and Sirius could hear the clinking of her belt falling against the floor tiles. Then another article of clothing thudding down. "I genuinely everyone."
She stepped in naked, sighing as the hot water hit her skin. Sirius gave a deep chuckle before his hands spun her around to face him.
He leant forward, their lips colliding messily. His hand ran up and down her side, grabbing and groping her breast that left her shivering, lips parting to let out a whimper.
"Mmm," he groaned into the kiss. "I missed you."
His chest felt as if it was going to burst; his heart hammering even louder, aggressively against the confines of his body.
His hold was tight, pulling her close.
"Sirius —" she gasped, whining against his lips as he grinded his half-hard cock against her.
Murder was worth it if that meant she was safe, happy and his.
"I love you," he chanted, again and again, her name spilling from his lips. He pushes her against the wall, his hand snaking down to drag along her folds and pushing his fingers in. "
You know that right? Everything I do is for you,” said Sirius darkly. He bit down on her bottom lip, leaving her breathless and dazed — kissed into submission as he curled his fingers, her soft moans mixing in with the water splashing down.
“Fuck! Please, I want more.”
Instead, his fingers slipped out, moving to align his cock, pushing the tip in. “I love you, love you —“
They both gasped once he fully bottomed out.
He barely gave her time to adjust, purposely wanting to overwhelm her — wanting her to never think about anyone but him — to never think about another man's cock but his.
His fingers dig into her hips, pace brutal and mean. And he relishes her moans jumping pitches from the thrust. “I’m never letting you go."
This is so random and I have a feeling this is gonna make people mad but here we go —
He probably was stalking his next victim, trailing them for days when he found you. He develops an obsession — kills anyone who gets too close or ‘interferes’ with your guys relationship. Think Joe from YOU. But he knows it’s fucked up — although he tries to justify it sometimes.
Sirius is smart — canonically we know that. However, he isn’t subtle. So it’s a fine line because he really thrives off the attention his ‘work’ gets. And he definitely has a district style but likes to change it often. Almost gets caught a few times.
It’s not as refined and pristine, but I’m thinking of how Hannibal (from the 2013 TV series) presents his kills.
OMGGGG FLATMATE SIRIUS CAN'T WAITT i can see it like he's super sweet with the reader cause she just arrived in London she doesn't know anything but her flatmate but IRLLL boiiii is like Joe Goldberg from You 😏😏😏😏 and he is infatuated with her and she doesn't have any clue ahahah ah
Hehehehe you're reading my mind!!! I just LOVE writing crazy characters and Sirius is the perfect marauder to make absolutely batshit crazy. And yes! Joe Goldberg and Love Quinn are actually really big inspirations for stalker/serial killer!sirius.
ugh I love the idea sm. Maybe it’s just the fucked up part of our brains that just wants someone to love us so much they’re willing to do anything lmfao. This is making me want to drop everything and write this fic.
