A/N: There seems to be the distinct possibility that I'm a sadist. After all, why else would I take such pleasure in making Izaya cry?

Just as a warning, the events at the end of this chapter are a little harsh. I'm not one for trigger warnings but I feel obligated to put a mild one here anyway.

That being said, enjoy!

Izaya felt like his world was ending. Probably because it was.

Shizuo knows, he knows what I am.

The sounds of Shizuo's pounding feet echoing behind him were like a horrible countdown, ticking away Izaya's last moments of freedom. His legs ached, his chest burned and every piece of him was saturated in swirling fear. Of course, it wasn't just fear, no, Izaya wasn't that lucky. Simple terror would have been easy to deal with in comparison, it was so much more straightforward.

No this was much worse, this horrible throbbing at the base of his skull, the thrumming in his bones that slowed him, pulled him back towards the very thing he was fleeing from. After years upon years of suppressing his natural instincts, Izaya's body desperately wanted to give in, wanted the beast, and he could only run from it for so long.

Shizuo was making very sure of that.

"Get back here you shitty flea!" the monster roared, sending chills racing through the raven. Izaya, who had never been one for appealing to higher powers, desperately begged every deity he'd ever heard of to make Shizuo just leave him alone. But he'd have been a fool if he expected anything to happen. The events playing themselves out in his life transcended godly intervention, this was the worst of the human condition, the base that societal interaction had been formed on.

Alphas and Betas finding and taking mates and Omegas rolling over and praying they didn't get hurt.

After spending his life avoiding fate, Izaya's body wanted nothing more than to be possessed and to be dominated by the monster chasing him. It had always been a struggle associated with meddling with Shizuo, that fine line between what his body craved and what his mind feared. Now the line was gone, erased by one careless mistake and the natural ties that bound him to his enemy.

Soul mates? Feh, nothing more than a fancy word for biologically dictated oppression.

But for all his brilliance and natural intellect, Izaya couldn't see a way out of this. The waves of powerful Omega pheromones coming off of his skin would lead Shizuo right to the raven, no matter how much distance he managed to put between them. As if that wasn't enough, Shizuo's own pheromones clouded up Izaya's mind. If there was a solution to his problem, Izaya wasn't in any place to see it.

I want it, his body screamed even as his mind rebelled. I want him, my soul mate.

And it was that desire, more than anything else, more even than the fact that Shizuo knew he was an Omega, that scared him.

A burst of Shizuo's pheromones caught up with him and Izaya stumbled, almost tumbling to the pavement. At the last second, he threw himself into the wall to his right, using it to steady himself before staggering on. Unfortunately, his reflexes were slowing down as his body insisted that, whatever Shizuo intended to do, Izaya would be absolutely fine with it and he should let it happen.

I can't, I can't ever give in!

Pulling every last bit of reason from the depths of his mind, Izaya tried to calculate the best possible method of escape. The rooftops, no matter how unlikely he was to get to them before Shizuo caught him, were the only way. Without a second thought, Izaya darted into the next alley, hoping, praying, that he'd make it out of this mess alive.

A moment later his head cracked against the brick of the alley as one-hundred and fifty pounds of rutting Alpha slammed into him and pinned him against the wall. Vision blurring momentarily, Izaya became acutely aware of the overpowering scent of Shizuo surrounding him from all sides and whimpered pathetically even as he struggled to get away. Panic allowing him to ignore the screaming ache that was spreading through his body, Izaya fought the beast's hold desperately, his breathing uneven and his eyes unwilling to meet the fire glaring down at him.

"What the actual fuck flea?" Grabbing his chin in rough, calloused fingers, Shizuo jerked Izaya's chin around so he couldn't avoid looking at the monster. Even though the contact was rough and unwanted, the raven whined pathetically as the feeling of Shizuo's skin against his, the warm breath spreading over his face, made his knees weak. With everything he had, Izaya stared at the beast with anger, trying and failing to keep the fear and desire out of his eyes.

"What the fuck?" Shizuo repeated, his voice a roar. Izaya tried to swallow but his throat wouldn't work right. He needed to get away but he couldn't, not with the blond caging him in, keeping him from running. Fear made him struggle harder, fighting against a force he couldn't hope to overcome.

"Get off of me Shizu-chan," Izaya pleaded, his eyes unable to focus on anything for more than a few seconds at a time. His heat, which had been almost over just a few minutes ago, was in full effect, breaking down those sacred boundaries he'd kept in place for a reason. "Get off," he repeated, weaker this time. Above him, Shizuo's eyes had dilated and there was something feral spilling into the air around them. "P-please," he begged, tears in his red eyes, no longer caring for his ruined pride, only for his freedom. "Leave me alone."

"You're an Omega!" thundered the blond, no temperance to his fury. Unchecked it shook Izaya to the core, fear only making him struggle all the harder. I need a way out, I can't let this happen. His left hand went for his pocket, hoping to find a knife there, but Shizuo moved quicker. With enough force to grind bones together, Shizuo caught Izaya's wrist and pinned it above his head, leaving him in an even more vulnerable position. Instincts battled fear as arousal curled in Izaya's stomach, even as he kept looking for a way out. Every lungful of air chipped away at his defenses as Shizuo's personal scent invaded the raven's body and saturated his skin.

"You're a fucking Omega!" Shizuo looked equal parts incredulous and livid as his words slapped Izaya in the face. "All this fucking time-"

"So what?" Izaya just managed to snap, trying to conceal the wanting moan that bubbled up involuntarily from his mouth. Fighting how his throat threatened to close, Izaya spat, "That gives you no right to treat me this way you dumb beas~ah!" Shizuo cut him off effectively as he pressed himself against Izaya's lithe form, giving the raven exactly what he'd been trying to deny himself. As Izaya's eyes rolled back in his head and he bit back a groan, he tried to will himself to keep fighting, keep trying to get away.

Though fear dominated the forefront of his mind, a much more powerful force pushed him against the blond, wanting more, needing what he couldn't have. Izaya hated himself, despised every bit of his being as his traitorous body soaked in Shizuo's pheromones and all his blood rushed south. His face was red, his eyes were unfocused and little moans kept escaping him.

And all the while Shizuo pressed him harder into the wall, almost grinding against him as his eyes widened and his pupils dilated further in desire.

"That's why you were gone," the beast's roar had become more of a low growl, its softer pitch almost more terrifying than before. Izaya's mind was jolted back into the present, making him all the more aware of his own arousal and the erection he was pressing into Shizuo shamelessly. "You've been in heat," Shizuo said, barring his teeth. "You still are, aren't you?"

Instincts overriding every last shred of dignity he possessed, Izaya's hips bucked against Shizuo's and he could see the moan the blond swallowed back. "I hate you," he managed to hiss as tears escaped the corners of his eyes. This couldn't be happening, he couldn't let his instincts get the better of him. If this was what all his self-control was worth Izaya would never be able to face his precious humans again. Yet no matter how much fear flowed through him and no matter how much he wanted, needed to get away, Izaya couldn't so much as look away from Shizuo.

"I hate you," he whispered again, tilting his head back in an attempt to stop the water flowing freely from his red eyes. "I hate you, I hate you." He could feel the beast's breath skittering across his bared neck, so close to his scent glands, close enough to send goosebumps across his body and make his groin twitch needily. They were in an alley, anyone could have seen them but Izaya was too far gone to care.

And then Shizuo uttered the one word that could have possibly snapped Izaya out of his heat fueled haze.

"Mate?"

Izaya registered the shock and disbelief in Shizuo's tone only dimly. A sudden bolt of clarity drove itself straight through the raven and his free hand moved, born by an entirely different set of instincts. Fingers closing around the cold steel of his switchblade, Izaya drew it and in one fluid motion drove it into Shizuo's side. It wasn't deep enough to cause lasting damage, the raven hadn't even hit any organs, but it served its intended purpose in driving the blond back.

What have I done?

Unable to see clearly through the frightened tears obscuring his vision, Izaya glared at Shizuo, the Alpha's pheromones still affecting his ability to stand straight. As Shizuo opened his mouth, Izaya's panic welled up once more and he cut him off, not wanting to hear the words the beast was sure to say. "I don't care if we're soul mates Shizu-chan, I don't care if you think I'm yours!" The words flew off his tongue, the act of driving the blond away coming to him more naturally than breathing. "I will never have a mate and I will never let an Alpha control me. Don't you ever touch me again you monster!"

Without waiting to see what Shizuo's reaction would be, Izaya darted away, using this burst of adrenaline to get as far away from the Alpha as possible. My Alpha, my mess. Pheromones trailed behind Izaya like blood souring the air, easy enough for anyone to follow, even if they didn't have Shizuo's nose. Probably every Alpha around knew there was an Omega in heat nearby. It didn't matter, Izaya just needed to get away.

Taking to the rooftops, Izaya stumbled along until his strength ran out and he collapsed limply against the wall of a taller building next to the roof he currently resided on. The fearful tears came then without restraint. Curling in on himself, Izaya gasped as his stiff erection chafed against his jeans and his sensitive skin cried out in pain. He needed to get up, he needed to get out of there before Shizuo found him but he couldn't move, much less run. Everything hurt too much.

Izaya had failed himself. Shizuo knew. He knew. A bitter laugh escaped the raven's mouth as he tried to mop away some of the tears pouring down his ashen face. After everything, all the torture he'd gone through so he could lead the life he'd wanted to, Shizuo had ruined it all in a moment.

If I hadn't left my apartment today, or if I had taken more suppressants this wouldn't have happened, Izaya thought, hiccuping on a sob. I should have stabbed Shizuo the moment he attacked me, I shouldn't have tempted fate quite so often.

I shouldn't have given into my instincts quite so easily…

But it was over now, wasn't it? Shizuo knew what Izaya was, he knew the raven was his soul mate. Honestly, Izaya was surprised Shizuo hadn't stormed the roof already and forced Izaya to mate with him.

Izaya's face screwed up in fear, even though he knew it was irrational. Shizuo wasn't that kind of person, no matter what else he was. He wouldn't do anything of that nature if Izaya didn't want it. Besides, didn't the beast despise him?

No, the real problem was that Izaya would want Shizuo to pin him to the ground and fuck him senseless. Lip curling, Izaya pressed his forehead into his knees and tried to stop the pitiful tears still staining his face. Even if the monster was kind enough to wait for consent, that didn't mean he was going to be so gracious in the long term. Once they were mated, Izaya was as good as property, he'd have next to no rights. Shizuo could treat him as he saw fit.

And since they hated each other, all Izaya could foresee was pain and suffering on his part.

Retracting further into himself, Izaya shivered and hated himself a little more with every heartbeat. Some god I am…

His own pheromones choked the surrounding air, making it harder for Izaya to breath. A part of him just wanted to melt into the wall at his back but no, he was too prideful for that. Pride? Am I even permitted to have that as a male Omega? I'm a disgrace, thinking I could control myself when all I'm good for is breeding stock for the rest of the world.

So lost in his own misery was he that Izaya didn't notice the foul odor drawing closer to where he was until it was too late to do anything about it. Disgusted by the unfamiliar scents, Izaya's nose wrinkled and he stumbled to his feet, wiping away his pathetic tears as he did. Three leering men stood at the fire exit of the building, their scents identifying them as Alphas.

"Look what we have here!" One of them crooned and Izaya winced internally, feeling almost sorry for the human who had been cursed with such stupidity. "A little Omega." Fingers still shaking slightly, Izaya pulled his coat tightly around his body in an attempt to hide his still throbbing groin while at the same time fumbling around in his pockets for a knife. After Shizu-chan, these idiots won't be a challenge at all.

His fingers came up empty.

"Smells like the little slut is in heat," one of the others drawled, his voice painfully grating. Izaya felt a trickle of fear run through him. No, he always had more knives, surely he hadn't left the house with just one, what kind of an amateur would do that? "I wonder if he wants to have a little fun."

"Don't touch me," Izaya hissed, his back already to a wall, hands frantically pawing about for a knife. The Alpha's only grinned and drew closer, clearly delighted at finding such fresh meat to devour. I'm worth more than all of them, was Izaya's first thought but his doubts hit him full force and he almost stumbled. I'm just an Omega, I was made to be used.

"This one's feisty," the first commented, licking his teeth and making a horrible sucking sound. "I've never seen a male Omega before. Do you think he bites?" Usually, Izaya would have laughed. Right now, in heat and stuck with no weapons, Izaya could only hiss and pray they didn't come any closer. I can't fight back, I'm too weak and I have no knives. I'm at their mercy.

Izaya's stomach turned and he felt sick as he realized what was about to happen. No, I was, am, a god! I won't have pathetic human's defile me in such a way! But they weren't stopping.

As the nearest one reached out to touch Izaya, the raven shrunk back. "I said, don't touch me!" Suddenly, the ringleader of the three Alpha's seized his hair and dragged him away from the wall. Under normal circumstances, Izaya would have been able to fight back but in this state, he could do little more than whimper in pain.

"How dare you speak to your betters like that," the second hissed, his scent making Izaya's gut turn and revolt against him. "Do you know what happens to Omega's who don't know their place?" Izaya tried to scratch at the man's eyes but the Alpha who had first tried to touch him gripped his arms and pulled them painfully behind his back.

"They get shown it, forcefully," the first man spat as the one gripping his arms let a hand stroke up Izaya's thigh, finding his erection.

"Look's like the little whore's all ready for us," he cackled, making Izaya gag on the combined scent of unfamiliar Alphas and unwashed bodies. "What a willing Omega." Dirty hands started pawing at Izaya's clothing and the raven could do nothing but whimper and pathetically beg from them to stop, his body too weak to fight back.

As his jacket vanished along with his shirt, Izaya closed his eyes and tried desperately to shut off his mind. He could feel their hands, touching him everywhere, pinching and filthy and it made him want to be sick. Somewhere in the back of his mind, Izaya could still sense Shizuo's breath on his skin, making his entire body feel like it was on fire. Possessive, dominant. He wasn't supposed to want the beast but dammit he did! Desperately, he focused on those moments, ones he'd thrown away because he was too good to be touched by an Alpha.

And now he was about to be raped and there was nothing he could do about it. His pride would be stripped from him and in the end, all Izaya would be left with was a shattered mind and a broken body. He was about to be defiled so completely that he'd never be able to mend the holes it left behind.

"Open your eyes you damn Omega!" one of the men growled, the threatening words accompanied by a slap to the face.

As someone yanked the zipper of his jeans down, Izaya did indeed open his eyes. Staring straight ahead into the cruel, unfeeling sky, his entire body filled with to the brim with fear, Izaya whispered, "Shizuo, please."

But why would a monster come at the call of a god?

A/N: *smirks* I know, I'm evil. But be honest, you knew it was going to happen.

You had better hope I don't leave it on a cliffhanger for the next few months.

That being said, I'm not that mean, I know where to draw the line… Maybe. I hope the angst was to your liking.
