"You think Shizu-chan is an omega?" Izaya asked in disbelief. Of all the lies to come up with Mikado picked the most ridiculous of all. "Nice try."
"Think about it. Both you and Shizuo have been strange all week. The only time we have sex is after I've been close to him."
"Coincidence." Izaya shrugged. "Shizu-chan isn't an omega. It was the first thing I checked. I could of humiliated him if he was."
"What if he had the results changed?" Mikado persisted on his ridiculous theory.
"Shizu-chan doesn't like violence. He doesn't use it unless provoked. You're changing the subject."
"You don't believe me."
Izaya laughed. That seemed to annoy his boyfriend.
"Fine. Go into Shizuo's room."
Izaya tensed. "Why? Shizu-chan made it clear he didn't want anyone in there."
"If you won't go in there you have to admit the possibility of Shizuo being your mate." Mikado stubbornly folded his arms.
"...why not? It's not like the brute will ever know." Izaya shot a glare at the younger raven. Mikado pushed open the door and stepped inside.
Izaya followed stumbling back against the wall. His senses went into overdrive, his pants becoming painfully tight.
"What's wrong, Izaya-san?" Mikado asked calmly watching his reaction.
"Nothing." Izaya growled moving to leave. Mikado padded over to the bed. "What are you doing?"
"Proving a point." The teen answered rolling across the sheets.
"What is that going to prove?" Izaya stepped out of the room. Mikado shrugged closing the door.
"I'm coated in Shizuo's scent. Can you stay in control?"
x-x-x
Shizuo was an omega. Mikado knew it with certainty. Worse yet his boyfriend was probably in heat. It hurt as Izaya slammed him into the wall and bit deep into his nape.
Mikado shivered at the possessiveness. Izaya had him against the wall thrusting into him. His boyfriend wasn't in control. Izaya had most likely never loved him. Not as much as his mate.
He was a beta, a placebo for the both of them. Mikado had thought he was Shizuo and Izaya's everything. As it turned out he was nothing.
x-x-x
Izaya groaned coming to his senses. He was in his bedroom with no knowledge of getting there. Mikado lay naked beneath him spent and littered with bite marks. "Mikado-kun?"
"Believe me now?" The teen croaked.
"Shit. Did I-"
"I wanted it." Mikado smiled shaking a little. "So you've never loved me."
"No. That's I...I need to think." Izaya climbed from the bed. "Do you need help getting in the bath?"
His boyfriend wiped the tears from his eyes. "Just go."
x-x-x
He'd had both of them and now he had no one. Mikado couldn't help thinking it was unfair but after what he'd done fair wasn't what he deserved. After running the bath Mikado gingerly climbed in, tears dripping from his lashes. Izaya would be running after Shizuo, which would be a first. Maybe they'd get together maybe they wouldn't. As individuals they hated each other with a passion. As mates they craved each other with just as much ferocity.
It had been stupid to even attempt to get between them. But he'd managed two years. Those had been the riskiest and best years of his life. Mikado didn't know how he would move on.
The bathroom door flung open and Izaya was there.
"...I thought you left."
"Shizu-chan can wait." Izaya shrugged.
Mikado looked down. "But he's your mate."
"You're my boyfriend."
"I'm a beta. I'm no one special."
Izaya kneeled beside the bath. "You're my boyfriend. You're the one I chose to be with out of every human."
Mikado sniffed. "Shizuo was chosen for you."
"Yeah." Izaya sighed. "Like a pushy arranged marriage. I'm not going anywhere Mikado-kun." The informant cupped his chin lifting it gently pressing a kiss against his tears.
"What are you going to do about Shizuo?" Mikado asked looking away.
"I haven't thought that far ahead." His boyfriend shrugged. "Shizu-chan will have to come back, we'll talk then."
Mikado scoffed. "He's your mate. I don't foresee much talking."
Izaya leaned forward embracing him. "When did my little air conditioner become so sceptical?"
Mikado blushed. "You're getting wet! Let me go."
"Never. No matter what happens."
His heart fluttered but he couldn't bring himself to believe that. Eventually everyone was put in their proper place.
x-x-x
Shizuo returned close to midnight when he was sure both the flea and Mikado would be fast asleep. He hadn't wanted to return so soon but there was something he'd left behind. His pills. Without his pills he wouldn't have control. Having his heart broken was one thing. Being bound to an alpha without his rational consent was another. Slowly opening the door the blond padded across to his bedroom and silently slipped into his room. His fingers brushed over the light switch turning it on without so much as a click.
The pills were under his pillow. It should have been an easy task. Get in get out. As he reached the bed his knees buckled. Someone had been in his room. His alpha. Shizuo could smell the raw possessiveness. It smelt strangely familiar but he couldn't grasp who. His mind was fogging over. Shizuo doubled over feeling desire pulse through him. The front of his pants were wet.
"No." The blond growled. "Damn it." Reaching for his pills he cursed as his rough grab knocked them down the back of the bed.
"Shizuo-san?" Mikado asked from the doorway. Shizuo didn't answer pulling out the box from his brother. "You came back. Can we talk?"
Shizuo growled in response diving under the bed. The tray cracked in his hand. Grabbing a handful of pills he swallowed them down waiting for his heat to subside. "Shizuo-san? I'll be in the other room when you're ready."
Ready? His heart wasn't ready. The kid hadn't apologised or sounded regretful in the least. But maybe there was something going on he didn't know about. A family tragedy or something to do with school. So much for complications. Closing the door he got changed and found every excuse to delay his talk with the kid.
Eventually he stepped out surprised to see Izaya there too with Mikado sitting on his lap. Shizuo hadn't looked before so he hadn't seen the crude bite marks all over the teen's throat. It was a punch to the gut.
"Um, we need to talk." The kid mumbled. Shizuo clenched his fists. He looked between his boyfriend and the flea realising what was going on. He'd been a fool. "A-are you an omega?"
Shizuo masked his surprise with a short burst of laughter. "You're funny kid. What's that on your neck?"
"Shizu-chan we've all got secrets it seems." Izaya shrugged with a smirk. "Mikado-kun has been cheating on you with me. I'm so glad it wasn't the other way around."
"...How long?" He asked feeling the pain twist stabbing deeper.
"All along." Izaya tossed another shrug.
"I wasn't asking you flea." Shizuo growled looking at his guilty boyfriend. That wasn't true. It couldn't be true.
"S-since the start." And there it was. The truth he hadn't figured out.
Shizuo felt his heart being ripped out. Two years the teen had been going behind his back sleeping with Izaya. "So that's it. You again damn flea. So what you two were laughing at me hah?"
"No!" Mikado cried but didn't move. Apparently Izaya's lap was too much of a comfort.
"I didn't know either Shizu-chan." Izaya smiled. "I only found out recently."
"You the great informant?" Shizuo asked in disbelief. "Well it looks like you two have made up."
"That's not why-" Izaya clapped a hand over the kid's mouth.
"You're not very good at this Mikado-kun. It's a wonder how you played us for so long." Izaya looked at him and Shizuo found himself taking a step back. "Mikado-kun is sitting on me to stop me from attacking you. So here's my secret. I'm an alpha, Shizu-chan."
Shizuo snorted. "Bullshit. That's-"
"Ridiculous? No more so than you being an omega. What's happening to us makes sense now, ne? I was the one that bit Mikado because he was covered in your scent."
Shizuo shook his head. Izaya was his mate? That couldn't be. Of all people the last person he'd considered was Izaya. "No fucking chance in hell." He snapped. He wanted to leave the apartment but he couldn't show his back to the flea. Not if it was true.
"That's what I thought too." Izaya wrapped his arms around the teen. "Except I spent a week staring at your bedroom door and ignoring poor Mikado-kun whilst you hid away coping with your heat."
"What is this?" Shizuo snarled glancing at his door. He should have slipped his pills into his pocket.
"Well all our secrets are out in the open now. I'd say it's time for a new relationship. See Mikado-kun here is my boyfriend and you're my mate. I can't let either one of you go."
"So what? You want to share the kid? Same as the first time around? So what does that mean? I get Monday's, Wednesday's and Friday's?" Shizuo snapped taking another step back. He'd have noticed if Izaya was an alpha. Besides when they'd first moved in he'd helped the flea through his heat. Hadn't he?
"Not at all." Izaya purred nuzzling the kid's neck. "I don't see why we can't all be together."
"Piss off. The both of you." Shizuo stormed into his room and picked up the box from Kasuka. He wouldn't cry. He wouldn't show weakness especially in front of the flea.
"Shizu-chan you're not leaving." Izaya pushed Mikado from his lap and flew towards him. Shizuo put up his foot. Izaya dodged moving to his side. Shizuo wrapped a hand around his throat and slammed his so called mate against the wall. But even at the first touch he knew the damning truth, maybe he always had.
"You being my mate means nothing." Shizuo rumbled. "Stay the fuck away from me flea. You and the kid."
"Where are you going to go protozoan?" Izaya clawed against his hands. "If you let another alpha-"
"What I do is my choice. Get it flea? I don't believe in fate."
"That's not what you were saying earlier today. We're tied together, Shizu-chan. There's nothing you can do about it." Like a monkey Izaya lifted his legs and kicked the box from his hand. The contents spilled out. His clothes and the trays of pills. Shizuo went bug eyed as they cracked going everywhere. "Your heat isn't stopping. It's not going to."
With a growl of rage Shizuo tossed Izaya across the room dropping to his knees to pick up his pills. Handful by handful he scooped them back into the tray. His fingers tingled where he'd touched the flea.
"Ne,Shizu-chan. You know it's only going to get more painful." Izaya's voice softened. "We've been exposed to each other too long. Why don't you give up and be mine? The pain will go away."
"Piss off flea!" Shizuo snarled. Izaya ran over to him kicking at the pills. "Stop it."
"Make me." Izaya moved to kiss him but Shizuo aimed a punch meaning to hurt. The flea danced away. "I don't need to force myself on you." Izaya shrugged. "Mikado-kun and I had sex on your bed. What did that do to you, hm? The same as it did to me being in your bedroom I suppose."
"Izaya-san!"
"It's my scent that drives you further into your heat." Izaya smirked. "How long do you think you can resist that for?"
x-x-x
It wasn't fair. Izaya and Shizuo knew they were each other's mates. There were no secrets between them. Shizuo was trying to leave and Izaya was being mean about it. He couldn't imagine the pain Shizuo must be going through. Those little pills were all that was keeping the fortissimo together.
Mikado remembered there was a tray on Izaya's bedside table. He didn't like to see the blond on the floor desperately gathering up his pills. "Izaya-san, that's enough." The teen pleaded clutching at his boyfriend's arm. Izaya was trying to break his mate down. But he knew Shizuo wouldn't break.
"It's okay, Shizu-chan can take it." Izaya grinned. "Isn't that right?"
"Izaya-san,why are you doing this?" Mikado pulled harder. His boyfriend didn't answer. Letting go he hurried to Izaya's bedroom and grabbed the tray of pills. Clutching it protectively to his chest he returned seeing Izaya kissing the fortissimo.
The pair tumbled to the floor. Izaya held the blond's wrists. "Izaya-san? Shizuo-san?" Mikado asked hesitantly.
Shizuo looked dazed, Izaya growled at him as he got closer. It was the heat. Placing the tray on the chair he threw himself on top pushing Izaya off.
"What the-" Izaya got up standing in his bedroom. "Ugh, again?"
Mikado looked down at Shizuo. He looked pissed. "Damn flea, what the hell did you think you were doing?"
Izaya shook his head. "...I think you should go after all, Shizu-chan?"
Mikado went to object. "Hah? Because you can't keep your dick in your pants? I'm not some weakling flea. You try and touch me and I'll knock you flying."
"The times you've laid a hand on me are minimal Shizu-chan." Izaya jeered.
"Maybe that's because you always ran away like a coward. Don't start shit if you're not going to finish it!"
Izaya sighed. "Shizu-chan, I'm your mate."
"So you keep saying."
"You know what that means."
Mikado looked between them feeling left out. What had he missed? Still if Izaya could convince Shizuo to stay then it would all work out.
"You're going to try and jump me all the time?" The fortissimo grumbled sitting up. "I can handle myself, flea."
"I'll be here." Mikado braved. "I can watch over you both." It sounded pathetic after what he'd done. He looked over to Izaya but not Shizuo. His betrayal was still fresh.
"Of course you will Mikado-kun, you're my boyfriend." Izaya grinned. "I can't leave my little air conditioner on the streets. Isn't that right, Shizu-chan."
"Your home your rules." Shizuo rumbled.
Mikado felt his heart sink hearing the door slam. Izaya held him patting his head. "He'll come around." He didn't think that was the case. His paradise with his two boyfriend's had become a prison with one boyfriend and his boyfriend's mate.
