Anyone who lived in Ikebukuro was well acquainted with the way the town ran, and who ran the town. Those who were ignorant quickly became tutored, most often painfully or fatally. This is why, as a certain blonde man stalked his way through a busy street on a boiling Saturday afternoon, his path was found quite unhindered by the throngs of wary pedestrians. They watched as he suddenly stopped, whipped his head to the left and right, then swore violently. The mothers shot him looks of loathing, clasping their hands over their gleeful children's ears.

Shizuo Heiwajima snapped his toothpick into halves, fourths, and eighths, grinding the stick into a soft powder and gnashing his teeth together. Today was turning out to be a very bad day. Everywhere he turned, he was being nipped at by that damn flea. At every swivel of his head he saw a dash of black, a streak of fur, always gone by the time he had focused on his target. He knew that the bastard was watching him, taunting him, and waiting.

Shizuo opened his hand, watching the wind steal away the remains of the toothpick. He had promised Tom that he wouldn't start any fights while his friend was away, and he was pretty damn sure the flea knew it too.

His eye twitched as another flash of movement darted across a rooftop. He tore his eyes away, hissing under his breath. Izaya wasn't going to quit this anytime soon. He needed to deal with this now, before he began destroying public property again. He broke away from the crowd, turning into an alley. Once he had put enough distance between himself and the rest of Ikebukuro, he leaned against the wall, lit a cigarette, and waited.

It didn't take long.

"Shizzy-chan…"

Shizuo snapped his head up, body tensing. "Izaya…" he acknowledged through a forced grin. The flea was dangling from a fire escape, arms entwined through the rails, a devil's smirk on his face.

"You've been so quiet lately, Shizzy" Izaya drawled lazily, eyes never leaving Shizuo's. "It's so nice to walk down the street without ducking for flying trash bins."

"Oh? You've been following me an awful lot for someone who likes to keep their organs intact." The blonde countered, clenching his smoke between his teeth. "Usually I have to seek your sorry ass out. So nice to know you seek death at my hands, I'm truly more than happy to oblige."

"Ah, I'm afraid not" Izaya sighed dramatically, flipping over the rails, landing a few feet away from the other. "I do not want a shameful death at the hands of a brute like you. But if you like, I can direct you to some competitors of mine tha-

"If this is all, I'm done here." Shizuo snapped, making an abrupt turn down the alley. The flea was wasting too much of his time for this crap.

"Wait."

Shizuo stopped midstride as he felt lanky arms encircle his waist. He felt the other watching, testing for his reaction. He tensed as he felt Izaya's face slowly bury itself in his shoulder blade. He lifted his arm and took a slow drag of his cigarette.

"So you're here for that then." Shizuo said, his voice empty of feeling.

"We haven't played that game in so long, Shizzy." Izaya murmured, and Shizuo could feel the grin on his back.

"And if I don't want to play?" the blonde replied coolly.

"It's not really your choice." Izaya replied, standing on his toes to give Shizuo a soft nip on the ear. "Otherwise…" he continued, nuzzling the other's neck, "I'll just keep coming back until you snap."

Shizuo pushed the man away, a low growl echoing in his throat. They stood apart, sizing up the other as Shizuo clenched his fists. Izaya absently fingered the blade in his pocket, watching the blonde carefully.

"If…" Izaya blinked, surprised. "If we play that game, Rule Two is being extended to two weeks."

"Unfair," the brunet protested, "It's hard enough as one."

"Two weeks, bastard, or we don't play." Shizuo repeated calmly, eyes hard. "I have much better things to do then waste my time with you."

Izaya sighed, holding up his hands in mock defeat. "Fine. You're so cruel, Shizzy-chan."

"Hardly." Shizuo replied, retreating down the alley. "I'll be back at my apartment in an hour. Be at the door or you're not getting in."

Izaya's eyes glittered as he smirked at the other's retreating back. "Like I couldn't get in on my own."

Shizuo grudgingly trudged up the stairs, dreading every step taking him closer to his apartment. He was regretting taking up Izaya on his offer, and had delayed his trip home by a half-hour. He figured he couldn't put it off any longer before his apartment was destroyed, and was now ascending to his floor, fervently praying the hallway would be empty. He hesitated on the last step, took a deep breath, and rounded the corner.

No such luck. The bastard was lying there asleep, stretched out like a cat in front of his doorway. He was earning several disapproving glares from his neighbors, and he understood why as he glanced down and saw the carpet had been carved into patterns by what had unmistakably been a knife.

"You son of a bitch!" Shizuo snarled, slamming his foot into the other's side, jolting the man awake. "I'm gonna have to pay for that!"

Izaya muttered sleepily, rolling over and propping himself up. "'Oo were late. 'S your own fault." he yawned.

Fumbling angrily with his keys, Shizuo unlocked the door and threw the other man in by his collar. "How is it my fault you have an attention disorder?!" he barked, slamming his door shut.

"It's your fault for being purposefully late, Shizzy-chan" Izaya smirked, pushing himself up to his feet, "Or maybe your watch broke? Just like everything else you touch-"

Izaya was cut off by a large hand wrapping around his throat. He choked as felt himself being picked up and slammed harshly into a wall. He clawed at the vice-grip on his neck, fighting for consciousness, as Shizuo leaned in close.

"You are so damn annoying." The blonde said quietly. Izaya struggled to breathe, knife forgotten in his panic, as Shizuo slowly tightened his grip. Just as his vision went hazy, Izaya felt himself being released. He stumbled, slumping against the blonde. He gripped at the other's shirt as he coughed violently.

"Aha…ahaaa" Izaya panted, a small grin working onto his face. "Always... so forceful…"

"Shut up." Shizuo growled, grabbing Izaya's chin and yanking him into a harsh kiss, effectively cutting off further annoyances. The brunet tilted his head up, relinquishing a small sound of pleasure as he wrapped his arms around his captor. He deepened the kiss momentarily before being forced to tear his head away, gulping in air. He looked up at the blonde with an apologetic grin. "Need… more breath…"

"Hn." Shizuo grunted. "Just be quiet." He leaned down to bite at his prey's neck, vaguely enjoying the guilty shudder that wracked through the other's body.

In truth, he didn't really mind playing these games with Izaya, although he hadn't been extremely open to the idea in the beginning. The first time Izaya had suggested it, he had ended up in the hospital with three broken ribs and a fist indent in his skull, something Shizuo was very proud of. For a while the other had let the idea drop, but after a few months, he had proposed it again with a set of rules and 500 feet between them.

The first rule was that the game had to be a secret, something Shizuo had no trouble complying with. The second was that after a 'round' had been played, both of them had to leave the other alone for a full week, although currently it had been bargained to two. Izaya couldn't taunt Shizuo, Shizuo couldn't hunt Izaya, and both of them had to stay out of the other's sight. If either of the rules were broken, the game was over.

Personal reservations aside, a whole week without the flea had been a sorely tempting offer, especially since the flea had made it his mission to be as irritating as possible until the blonde reached a decision. After one particularly irritating day, Shizuo had had enough. He had sat down on top of the bleeding brunet, wiped a cut on his cheek, and calmly told the man he accepted. Izaya's only reply had been a quiet smile.

So they played. The 'rounds' had been infrequent at best, but the rate seemed to be increasing, with Izaya initiating more and more fights so that Shizuo would relent. It had always been hard for Shizuo to find a girl for pleasure, due to his hot-temper and distaste for prostitution, so he dismissed any feelings of desire as pent-up stress. He had never asked Izaya why he enjoyed this game, but he assumed it was for the same reasons. His conclusion was that the other's charming personality was enough of a deterrent for any woman.

He was snapped back into reality by a harsh rub against his crotch. He glared down at Izaya, whose hand guiltily retreated to clasp behind his back again.

"Sorry," Izaya grinned impishly, reaching up to nuzzle his ear, "You looked a little distracted."

Shizuo growled lowly, bending down to hook his arm under Izaya's hips. The brunet's initial groan changed to a yelp of outrage as he was slung over the man's shoulder.

The blonde ignored him, slowly navigating his way through the apartment. He was halfway to his bedroom when he let out strangled noise, stopping dead in his tracks. The bastard had decided to make use of his dangling arms, and was now lightly fingering the crook of the blonde's back. He heard Izaya snicker as the brunet's hands snuck further down into his pants, playfully groping the flesh he could reach.

Shizuo snarled, patience worn out. He abruptly turned towards the living room, making his decision. He tossed the other man onto the couch, enjoying his look of shock. His good mood faded as Izaya's eyes began glittering mischievously.

"My, my, the couch today, Shizzy?" Izaya purred, watching as Shizuo straddled him, eyes dark. "How vulgar…"

"You lost bedroom privileges." Shizuo snapped, harshly pulling down on Izaya's jacket. The brunet arched, allowing the other man to slip his jacket off his shoulders. As he wriggled, trying to remove the rest of the article, Shizuo suddenly pushed on his chest, forcing him back down.

"Hey!" Izaya protested, struggling to free his hands of the constricting fabric.

"You lost a lot of privileges." Shizuo said pointedly, nipping at Izaya's collarbone. The other shuddered violently, eyes glazing over.

"Oh… am I going to be punished then?" he asked breathlessly.

Shizuo rolled his eyes, then his hips, delighting in the low keening noise from underneath him. He lowered his head against Izaya's chest, slowly tracing the outline of his body, reveling in the delighted gasps. The man was so damned thin, and Shizuo would admit he had a nice curve. He moved his hand down to Izaya's crotch, feeling the heat pulse from beneath the thin layer of fabric. He smirked, giving the bulge an agonizingly slow squeeze as the man writhed underneath him. Eyeing Izaya's neglected chest, he grabbed the shirt and pulled it up with his teeth, descending to suck on a soft pink bud. He continued his slow, teasing squeezes and licks while holding down the now almost bucking Izaya.

He saw the man straining against his jacket confines, desperately trying to pull himself against the other's body. With a quick glance, he determined that it wouldn't take much to bring the other to completion. He sighed inwardly, suddenly desperate to finish this quickly.

Izaya's eyes widened as he felt arms wrap around his back, pulling him against flush Shizuo's body. He panted heavily, trembling in ecstasy as he felt the man's hot breath against his ear.

Shizuo grinned, feeling Izaya's chin dig into his shoulder. He knew exactly how to finish this. He turned his head, nuzzling Izaya's hair, feeling the other stiffen against him.

"Iz-ay-a…" he groaned, grinding shamelessly downward. He felt the brunet arch, and quickly covered the other's mouth with his own, swallowing his scream. He stayed there for a while, waiting patiently until the other rode out his pleasure. When he was sure the other was finished he broke the kiss, glancing downward to read his expression. Shizuo blinked.

Izaya had fallen asleep.

Shizuo swore violently, then flopped back down on the couch, an irritated growl escaping his lips. He kicked the brunet a few times, trying unsuccessfully to rouse him. Groaning, he weighed his options. He couldn't leave the brunet outside his door, his neighbors disapproved of him enough as it was. He couldn't toss the man out the window, however enticing the idea was. And he didn't dare leave the man alone in his apartment. He snarled in frustration, hitting his head against the cushions. He glanced at the brunet in anger, grumbling as he reached over and pulled the other against him. Both arms encircled and trapped the sleeping man, assuring himself Izaya couldn't get up and cause trouble in his apartment. Letting out one last sigh of frustration, he closed his eyes, slowly drifting off.

Izaya creaked open an eyelid and smirked.

AN: There needed to be more Shizaya fics. No, this isn't a oneshot~ I will be continuing~
