Light's anger was threatening a revolt. He had been so calm and composed, minus a few punches and kicks every so often. He had done everything perfectly, nothing to raise suspicion. So why was he still tethered to this unearthly creature? He could almost feel the chain on his wrist shrinking, pulling them together, a hunched man inching closer day by day. L has an innumerable amount of traits that irritate Light, one of which is his irregular sleep patterns. This often led to him trying to get to sleep with an infuriating detective tapping loudly on laptop next to him. Tap. Tap. Fucking tap. And if he rolled the wrong way his retinas are instantly burnt from a glowing screen.

However tonight he had found a new one, one that is even more off putting. L had abandoned his notes and decided to just stare at him. Light presumed he would get bored and drift off eventually but every time he peaked his eyes open, the bastard was still siting there on his haunches like some sort of giant owl watching his field mouse. It had been well over an hour, Light tried to ignore it but he could feel the dark eyes still on him. A burning heat that was impossible to sleep through. The more he tried to ignore it the more intense it felt and his ferocity was boiling just below the surface. He would occasionally hear L's thumb find his way in to his mouth, usually the sign of deep contemplation. But what information towards the case could this possibly be providing him.

Then he felt the bed shift, he could feel L leaning over him. Feel his body heat and his breath connect with his own. And that was it, the last straw he had to go cool down before he did something stupid. His eyes snapped open to see impossibly big pupils inches from his face.

"I'm getting a glass of water." He didn't bother waiting for a response; he just rolled out of the bed and dragged along his baggage with him. He trod barefoot into kitchen and poured him self a glass of water. He hoped it would sooth him. It almost did. Until he saw the gremlin standing in the door way watching him drink. He could see his eyes staring at his throat as he swallowed. What was he up to?

"Ryuzaki, do you know how uncomfortable your constant staring is." He tried to keep his voice light and playful.

"It's my job to observe Kira." A monotone repose came from the doorway.

"Fine, I know you think I'm Kira. But is it really necessary to glare at me when I'm trying to sleep. Can you not at least wait until I'm asleep to get creepy?"

A thumb travelled up to his lips. "I wasn't glaring."

Light rolled his eyes. "It has been weeks, when can we get this chain off? Haven't I passed all your little tests?"

"The chain will be removed when you admit to me you are in fact Kira, then you will swap these handcuffs for much shorter ones."

Light felt like he was going to scream but instead he wrapped his hand around the chain and yanked the other man in to the light of the kitchen. It caught him by surprise and he tumbled to the floor landing in front of Light's feet, but just as quickly Ryuzaki flipped and his leg swung out to kick Light's leg under him toppling him to the floor too. L kneeled over him, his face mere centimetres from the other. "Enjoy this while you can Kira. It's going to be lonely when the both ends of this chain are only attached to you."

Light met L's gaze, his eyes were half lidded but his pupils strangely seemed bigger. And something clicked behind Light's eyes, some neurons splattered together and electricity tingled down his spine. A plan, a new plan. An…interesting plan.

"Why are you so obsessed with me being Kira? From the very beginning you've been set on pinning this ridiculous misplaced title on me. Why is that?" He leant towards Ryuzaki, who backed away slightly. This was indeed a dangerous game he was playing but he was sure his hunch was right, it's hard not to notice someone's little signs when you're attached to their wrist for so long.

L babbled on about how his findings statistically prove that he is but he needs more hard evidence to convince the force. But Light interrupted.

"I think you want me to be Kira."

"Actually Light, quite the opposite." Always so blunt.

"No, I think you want me to be your Kira."

"I don't think I'm following you Light." They had both risen to standing, one slightly straighter than the other. And Ryuzaki was monitoring Light quizzically.

"You want me to be Kira so you can lock me up and I'd be your dirty little plaything." Neither of them had broken eye contact. So Light continued. "You want me to be Kira because you're attracted to criminals." Light watched the detective's eyes widen then narrow, was he actually making him angry? Good, he's right where I want him. Light started circling Ryuzaki. Ryuzaki didn't move.

"Are you attracted to me. L" He let the pseudonym roll slowly off his tongue. Light watched Ryuzaki's shoulders tighten ever so slightly.

"I told you not to call me that Light."

"Or are you only attracted to me as the idea of Kira."

"I am not attracted to criminals." Light ignored him.

"Because if you want, you know, I could play along." His voice tickled up the back of Ryuzaki 's neck, he watched faint dark hairs stand on end. "I could be Kira for you, L."

"Is that a confession Light."

"I could pretend it is, if it…" Pause for effect; "excites you."

Ryuzaki turned to face him. "It doesn't." he almost spat the words.

"You're lying."

"Perhaps what you are mistaking for attraction is endurance and dedication to solving the case." Light almost laughed but he had to remain in character, L may be an intellectual of few comparison but when it comes to his own sexual desires he is completely repressed. Light had the upper hand and he knew it.

"I didn't take you as much of a liar L, clearly I misjudged you."

They were now both literally circling each other like some bad western film. Eyeing each other up, fingers twitching, waiting to see who would make the first move.

"Have you considered, Light, that you want me to catch you? That you are using this fictitious infatuation as leverage to confess. Maybe, because you're the one that wants me to fuck you."

The word sounded so alien coming from Ryuzaki, they both stopped pacing. Both surprised with Ryuzaki's usually so careful and considered vocabulary.

"Maybe I'll kill more if you don't, fuck me." He mimicked L.

"So you admit, you are the murderer: Kira."

"For tonight, Yes. I'll be your Kira."

In one quick movement he wrapped the chain around L's neck. L let himself fall in to the taller man unfazed.

Ryuzaki had expected as much, such child's play, no real game here. "If you kill me Light everyone will know you are Kira. You know I've already given instructions to…"

"I'm not going to kill you L. I'm going to let you fuck me."

L's breath caught, that was less expected. Light saw the reaction and chose that moment to tighten the chain. This time instincts took over and L reached his hands up to claw at the metal.

Light moved his lips to L's ear. I'm gonna kill every single police officer in Japan, L. They'll be no police, no structure. Then you'll need me even more, I will become the justice this world needs. I will be law. Unless you can convince me otherwise.

"You would kill your own father? You're sick Light Yagami."

"I'm not Light, tonight I'm Kira. God's don't have fathers. I would kill them all with out a second thought. But you can stop me." He ran a soft tongue up the shell of his ear to substantiate his point.

Ryuzaki elbowed him in the stomach and used the chain to flip Light over his back and he slammed on to the floor in front of him, keeping his throat safe and free. L stepped forward on to the younger man's neck. Light was trying to catch his breath but was also smiling up at him. He nuzzled his face against the detectives foot. Eyes closed like a happy little kitten.

"Light, stop what you're doing it's not going to work. I find it an insult that you think I would fall for such a childish attempt of manipulation…"

"There's no trick, the only thing you need to fall for is me. And I know you already have. All I'm trying to do is satisfy your urges." He said this between lavish kisses to the foot.

"I don't get urges for people like you."

"Oh but you do. That's why you watch me. Why you watch me sleep. Wishing you could just slip in. What do you hope will happen, I'll wake and pull you close, and then we make gentle love till morning."

L retracted his foot to kick him in the shoulder. But Light caught it and pulled him down to his level. He rolled on top of him pinning his arms above his head. Light bit his lip purposefully, watching L look up at him with wild wide eyes. L scooted down to make sure he was resting on top of the detective's crotch. "Should I kill you L?"

He felt the signature twitch he was hoping for.

"Do you want Kira to kill you, I could. I could do it right now."

Twitch.

"Or should I let you live and keep you tied up. After the law enforcement are gone who's going to stop me tying you up and keeping you. My own little toy. Your Kira's perfect opponent L. So smart. So beautiful." His hand skirted up under the loose white top.

"Stop it light."

"But you don't want me to stop it. I can feel you. I can feel how much you love it." Light had never seen L so angry, he was sure whatever was coming next was going to hurt but he couldn't stop.
