My Obsession

AN: OK, READ THIS. This oneshot is actually part of a series (which ill briefly explain more about in the bottom one ) but you should read Poison IV first if you haven't already. Why? Because that's the first in the series. XD

~My Obsession~

Matt was alone the second the sun had gone down, his roommate exiting in his costume with a large bag to collect candy despite his age; it suited Matt just fine to be honest. He had the lights off with only the glow of the television illuminating the room and spilling out the window.

He knew he would have a few good hours to play his games and enjoy time away from everyone. This was one holiday he wasn't forced to participate in and he reveled in the silence and space to think.

Despite that Matt was unsurprised at the bloody hand that slapped on his window nearly an hour later; so unsurprised that he went and made sure the door was locked before shoving the window open.

The less time spent hanging outside of his window the better, Matt thought.

The other stood at full height once inside, though he kept his expression wide and owlish despite the blood that was smeared across his mouth ruining the effect.

Halloween was always a special occasion for those at Wammys. Even more so considering whose birthday it was, and who could sneak around whilst masquerading. "Happy Halloween."

And just like that the spell was broken and a hand was fisted in Matt's hair, dragging him close enough for those slick lips to devour his own. Matt wasn't the one in control of the situation, he never was, but that didn't stop him from pushing the other away from the curtain-less window's gaze.

It may be Halloween but should anyone see them it wouldn't matter. Nothing like what they were doing was allowed, and certainly not with Beyond Birthday.

The moment they were away from potential ruin Beyond shoved him harshly against the closet door, the handle digging into Matt's back painfully. But despite that Matt made no move to shift away from it. Beyond had known it was there.

Over the years the dynamic of their odd nights together hadn't changed all that much, though as Matt had gotten older Beyond had gotten rougher, and seemed to find it amusing when Matt challenged him; when he went beyond his role in the sick relationship they had.

Matt watched as Beyond let his charade fall and a crooked grin stretched his lips and his expression became slightly manic, the mostly normal expression when the raven haired man wasn't trying to be 'L'.

Matt had never been fascinated with L, and knew for certain that if Beyond was actually L, that pale hand wouldn't have been allowed to pop the button on his jeans. Or those lips to even think of kissing him anywhere.

It was dangerous, to have continued their game for so long, and right under L's nose. But it suited them just fine.

It wasn't love... it wasn't...

But Matt didn't know what to call it either.

Cold fingertips caressed his hip and yanked his boxers and jeans down in one quick motion, leaving Matt aroused and exposed to the others gleaming eyes. Matt was always left wanting when those eyes slid away from him, always wanted to be in the others gaze and under his fingers.

Matt never complained when the touches strayed though, forever trying to restrain any moans or gasps or demands knowing that he could and would be left frustrated if Beyond felt like it. That part hadn't changed over the years. Beyond liked to test peoples limits, and Matt was hardly excluded. What had started as bi-weekly trysts had grown into deserted classroom romps and shower sex with Mello in the room studying.

It was stupid and highly insane and Matt loved it.

"Always so eager." Beyond commented, his wiry fingers going to wrap around Matt's erection.

"Each. And. Every. Single. Time." he punctuated the words with strokes and Matt couldn't help the way his eyes rolled back into his head from the touch, or how he dug his nails into the door. He didn't jerk into the touch, instead letting Beyond's hand move further down and caresses his inner thigh, once more ignoring his need.

Matt opened his eyes, peering lazily at the figure before him as his goggles were gently removed and tossed on the bed. Beyond had an odd gleam in his eyes, one not caused by the flashing red 'Game Over' coming from the television.

Matt held the others gaze even as a hand came up to cup his face; he didn't know what Beyond had in mind, and was surprised by the gentle touch of the lips to his. It unsettled him as Beyond wasn't known for being gentle.

But there was no slap, or bite of wracking of nails down his side afterwards, just the lingering burn of the sweet kiss which left Matt confused and oddly wanting more. Beyond moved his lips over to Matt's neck and whispered against the flesh.

"Trick." teeth grazed him, sharp canines nearly digging in before they were pulled back.

"or..." Beyond's jeans had disappeared along with his shirt, leaving Matt the only one with clothing, that being his striped shirt.

"Treat." Matt flinched at the spit covered fingers that prodded him, having never once been prepared in all the times they'd had sex. It was hasty but certainly not something Matt would complain about. Perhaps he wouldn't have to clean blood off the floor afterwards...

He expected to be flipped around and taken from behind, like always happened when Beyond had him against a vertical surface, so he was surprised when Beyond lifted him up, making Matt wrap his legs around him.

"Happy Halloween." Beyond murmured eerily, voice halfway between amused and aroused; an odd and disturbing combination coming from him.

He pressed in, holding Matt's gaze, and let his fingers dig into Matt's hips in the harsh manor Matt was familiar with.

Matt couldn't withhold a gasp at the completely pleasurable sensation and didn't register he had done so until Beyond's grin had become almost feral as he leaned in. "Scream." was all that was said.

Matt didn't understand. Was it a test? Or a request? It was breaking the rules. It was change, and Matt wasn't sure he liked how it unsettled him.

He didn't have a choice, that much was clear, when Beyond began to move slowly and teasingly within him, building up the pleasure that coiled tightly in his stomach. Matt bit his lips, tried controlling his breathing, tried digging his fingers into the other, but nothing he did stopped the tiny sounds that started to emerge from his lips.

Beyond's request, no... command, echoed in his mind until it was virus like and infected his ever fiber. Scream.

It had started off as a loud moan, his pleasure spot being hit with every perfectly aimed thrust, but Beyond had made sure it went further until it was something as close to a scream as Matt had ever gotten.

He let his head drop back to the closet door, soft moans from his lips, as Beyond jerked him off into completion as a treat. Matt was aware of the harsh way his legs clenched around the other during orgasm, and the way that Beyond had pounded into him the moment his pleasure had been reached.

Matt couldn't understand Beyond's actions that night, but figured it had to do with the date and nothing more. Beyond moved away from him afterwards, letting Matt's legs drop shakily to the ground, and stepped away.

Matt let himself slide to the floor, utterly exhausted, more so than he had been from sex in a long time. Beyond grinned widely at him, dried blood marring his otherwise pale features. A hand reached down into Matt's hair and brushed it to the side before the soft touch was gone.

"See ya."

And just like that, Beyond was clothed and gone through the window again, out into the masses of costumed children and teens with no one the wiser of the serial killers visit.

After all, the best disguises are often the most simple ones. And no one would look twice at some hunched over person with 'fake' blood on their face. Not on Halloween.

Matt sighed, a smile playing on his lips. He had to get the place cleaned, and not smelling like sex, but he was too tired to get up. Glancing at the clock he figured he had another hour before Mello came back.

He'd wait a little while longer, at least until his legs didn't feel like jell-o.

Damn, he thought, what a great Halloween.

-End-

AN: Happy Halloween. It's the night before right now as I'm finishing this, and I know its the day after as you read this, but I figured no one would read it ON Halloween. XD

So yeah, I wrote another one :P

And guess what, there are going to be two more in this BbxMatt oneshot series. Don't know when they will be out but I can tell you the name of the next one, it will be Pins and Needles. Canon never looked so twisted...
