So I wanted try my hand at some dark smut -shrug- my inspiration was Flesh. Don't judge because that song is hot as hell and suits alot of my OTPs by the way- trigger warning(?), if you aren't into really rough stuff or can't handle serial killer stuff this isn't for you. Also, hints of cannibalism. Don't bitch at me that you don't like this stuff when I warned you.

The sound of glass breaking echoing through the otherwise silent apartment went unnoticed by the two bodies slamming against the wall, bloody and riddled in cuts and scrapes. The shorter male, pressed against the wall, harshly latched his teeth onto the taller's lip and earned a pleased growl from them both when he tasted the coppery, crimson liquid on his tongue. He craved it- they both did.

Their clothed hips rolled in sync with each other while the bloody shirts were thrown recklessly to the floor, one of them catching on a vase and making it fall on the hardwood floor. The second of many things to break that night. Neither of them noticed, again for the second of many times, and continued their harsh bites and sucks on their necks and shoulders.

"Fuck-!" The shorter male called out suddenly, head slamming back against the drywall and making a small indention. "Fucking brat, that hurt." He muttered, feigning anger but arousal and lust heavy in his voice. He glanced at the bleeding mark on the curve of his shoulder and shivered when he could very clearly see each and every tooth mark. He moaned in an intoxicating pain when he felt stinging from the tongue digging into one of the larger marks. He bucked his hips against the other male's impatiently while reaching down to take off their belts, legs going around his waist. One at a time the belts were gotten rid of, one thrown and slamming against the back of the couch and the other hitting a window; the buckle cracking the corner.

He knew it would get worse though. And oh so hot. They did this once a month, have been for years. Any more than that and people would get suspicious and they would get caught. They couldn't afford to get caught, not when they had urges so bad. Not when there was people to punish.

This nights killing had them hungrier than they'd ever been before, he couldn't say why it was just there. That growing need for sweet release. He needed it. They needed it. And neither of them would leave each other until they both got it. Even if that meant raping or being raped. Very rarely did it come down to that though and even more rarely did one of them not enjoy it.

They craved the rough treatment, the biting, the fighting, the rough sex.

They always started with a fight.

They would kidnap three people who had done wrong. They were usually child molesters and rapists that got away scot-free for one of them, murderers that got away on the same charge for the other. They would meet at an empty warehouse at the piers when they found their three, criminals turned victims tied on operation tables gagged, blindfolded, and tied up. They would exchanged who wanted what criminal and start their evening.

Eren was messy. He didn't make his victims suffer though, usually suffocating them before he started cutting and dismembering them. The younger male was almost always the first one to finish and the first one be covered in blood.

Levi was more careful but He made his victims suffer. They deserved it after all that they had done. He would treat his first victim "with care" and cut off each finger one by one, then their toes, then their extremities. Whether male or female, he loved it. He would torture his first and second victim unlike Eren. By the time he would get to his third, Eren was almost always done and hovering over the opposite side of the table ready to help. They both sometimes had more blood on their chins than the rest of the body by that time.

So crazed with blood lust when they finished with Levi's third they could hardly think enough to recognize each other before one of them threw the first punch to knock the other off kilter. By the time they recognized each other, one them always had a black eye, usually Eren, and they were both covered in cuts from the knifes they used previously. Rarely did they need to go to Hanji for stitches.

The bedroom door slammed open and Levi was roughly thrown into the plush mattress while Eren stalked to the closet and drug out a box.

'So its one of those nights.' Levi thought as he watched Eren lift black fuzzy handcuffs and a piece of rope. One was for his wrists, the other his ankles. "As long as there's no marks from the cuffs, Brat." He said simply before getting rid of his now painful pants and briefs. He held his arms out when he received a nod and the cuffs were put on, being pushed back onto the bed once they were comfortable. Then his ankles were tied together. To tight for his comfort but the marks wouldn't be seen nor would the rope cut off circulation so it didn't matter. It never mattered. The only thing did was them pleasing each other and they would bear whatever marks necessary to find release in each other.

I understand that this should be a one shot instead of a chapter thing but unfortunately I can't have more than 900 words on one note (I'm using my phone so please understand) Please review! :D I'm always open for criticisms!
