The favour

"I need a favour." Kadota said quietly closing the door behind him.

Izaya looked up from his laptop, cross legged on the bed. "Depends on what it is."

"Switch roommates with me."

Izaya raised a brow. "Why?"

"You know why." Kadota said through gritted teeth.

"Your current roommate is Shizuo Heiwajima. He has a reputation." Izaya brought up the student's details and whistled. "The guy lives in detention it seems. So what's the problem? You sleep with him?"

Kadota crossed his arms to his chest clearly uncomfortable. "He hates me."

"No one hates you." Izaya objected.

"Well he does. Besides you don't like sex, so it won't be a problem to have him as your roommate."

"It's not that I don't like sex, it's that it doesn't do anything for me. I'm asexual."

Kadota sighed. "Whatever label you are. Please?"

Izaya studied Kadota. "Are you sure you're not the problem?" Kadota glared at him. "Alright. My roommate was expelled so you'll be by yourself. I'll take Shizu-chan."

"Thank you."

Shizuo had no problem leaving his dorm room. He wanted to be gone. Kadota looked his way and Shizuo clenched his fists walking straight past the other student. He could hear his teeth grinding in his skulls, his nails biting into his palms and the betrayal lodged like a thorn in his heart.

He didn't say anything until he found his new dorm. The student council president. But at least the room was bigger and had its own bathroom. It was what he needed.

Knocking on the door he waited for it to open. He'd seen the president behind the podium at the welcoming assembly. "Ah, Shizu-chan. Your side is all clear for you."

Shizuo tried not to stare at the president's red eyes, instead staring past his shoulder. "Thank you." He said quietly walking into the room and setting down his stuff. There was a folded screen leaning against the wall. "Is it alright if I use that?"

Izaya's gaze flicked to where he pointed. "Sure. But the last student that used that was trying to hide drugs. Door gets locked at ten, no drugs and no other students."

Shizuo paused and nodded. "Sure. But I can use the bathroom whenever?"

"Go ahead. I'm sure Dotachin told you I'm asexual?"

"Might've." Shizuo shrugged. "Doesn't bother me."

"No? You're aware of your reputation?" Izaya sat on the bed looking both relaxed and curious.

"As the school slut? Yeah, I'm aware." Shizuo grumbled. "Not like I'm the only one though."

"True, but you're more brazen of the bunch. You're not waiting for your soulmate?"

Shizuo shook his head. This time he didn't laugh bitterly. "No point, wouldn't work out."

"Ah, so it's not Dotachin then?"

Shizuo scowled, biting at his inside cheek. "No!" He snapped. "Sorry. Look, I'll obey your rules. There won't be any problems."

"Alright then, Shizu-chan." Like that he was dismissed, Izaya clicking away at his laptop. Shizuo took his time setting his belongings out, losing himself in thought.

Soulmates were real. Everyone was born with a unique mark that only had one other to pair with. At birth they were given one clue. Shizuo's was simple. His soulmate would never have sex with him. Given his condition, he could never be with them.

People took him as a whore, a slut, a home wrecker and an abomination to the system. Kadota had told him he'd had an addiction. Shizuo closed his eyes still feeling the cuts the handcuffs had made as he'd tried to escape, he could still hear his begging and crying. It was 'help' he hadn't asked for.

"Shizu-chan?" Shizuo blinked and turned to Izaya. "Something wrong?"

Shizuo frowned glancing down at where he was rubbing at his wrist. "No, nothing." Shaking his thoughts away he unpacked the rest of his stuff and set the screen to split the room. There was already an existing line down the centre. Laying back on his bed, Shizuo curled into a ball and finally got the sleep he needed.

His new roommate was asleep. Shizuo didn't snore, but there was a sudden tense silence that made Izaya stop typing and move behind the screen. Shizuo was curled into a tight ball, his wrists and ankles visible where his clothes had pulled back. There were healing cuts all the way around both ankles and wrists. Not a blade. The indents were deep and the marks spoke of desperation. Handcuffs. Someone had chained his roommate.

"Did you rape Shizu-chan?" Izaya asked when Kadota came to his office to check on how Shizuo was.

"What? No!" Kadota hissed. "Is that what he said?"

"Shizu-chan hasn't said anything. But the marks on his wrists and ankles tell a story of their own. You chained him."

Kadota sighed sitting in front of his desk. "Yes. I was trying to help. The teachers are putting in complaints, he's getting into fights with soulmates. I chained him, so he couldn't sneak out at night."

"And? Did it help?"

Kadota went pale. "No. He spent the night crying and begging, trying to escape. I wanted to help with his addiction. But the way he looked at me, it was as if I'd tortured him."

"Did Shizu-chan consent to being chained?" Izaya asked.

Kadota tensed. "No. I told him it was for his own good."

"I have to report this. I'm going to suggest Shizu-chan see the school therapist."

"He has an addiction that will get him killed." Kadota said.

Izaya didn't think it was like that at all.

Izaya was writing his report. He'd already recorded the injuries on Shizuo's body and Kadota's answers. Both were easy, since Kadota was feeling guilty and Shizuo was asleep.

So began his observation. Shizuo woke up early and spent up to an hour in the bathroom. He went to classes, ate normally, spent another hour or so in the bathroom and then took sleeping pills. It was clockwork. Not the pattern of an addict.

After a week of the same thing, Izaya came to a conclusion. Shizuo had an undiagnosed medical condition. He didn't know if it was psychological or physical but Shizuo's body needed sex and Kadota had taken that away. Izaya sent his report to the headmaster, head of year and the school therapist.

Kadota was suspended for a couple of weeks. No one cared because Shizuo-medical condition or not-was an anomaly in the soulmate system.

Shizuo was thankful to Izaya. The council president had tried but he knew he was sick. The school therapist had done three sessions with him, but that was solely to stop any complaints towards Kadota. No one cared.

So he kept to his routine until he was told no, trying to buy more sleeping pills. His therapist wouldn't give him the pass he needed and like that he was set to suffer.

The first day was a nightmare. Shizuo lay in bed staring at the ceiling, listening to the clock tick painfully slow. His cock was already painfully hard, his balls full and aching for release. Shizuo sighed and went into the bathroom.

Shizuo broke his rules a week after the school had stopped providing sleeping pills. Izaya couldn't do anything about it. Typical adults trying to stay to the system.

What he could do was track his roommate down. He found Shizuo talking to the head of the disciplinary committee. Thankfully the room on the other side was flimsy and eavesdropping wasn't an issue.

"Detention isn't going to work anymore." Mikado Ryugamine spoke. "They want you out and detentions are just an excuse to get you expelled. I've confiscated a batch of sleeping pills another student was trying to sell. They should keep you going for a month. You need to join an after school club."

"Like what?" Shizuo grumbled.

"I don't know yet. But there is a teacher without a soulmate and the detention students. It takes five students and an adviser to start a club. It should help with the hyper sexuality." Mikado explained.

"What about the girl? You said she had it too."

"She's dead, Shizuo. Apparently a traffic accident. You have a condition that interferes with the soulmate system. It's in the archives and they will do all they can to get rid of you."

Shizuo blew out a breath. "So why don't they? They have me isolated in a school. Are they waiting till I graduate."

"It's not you they're waiting on." Mikado said after a moment. "Think about it. Losing your soulmate is a void, you never get back. Few recover and the mortality rate isn't high. They kill you, they damage your soulmate. I think they're waiting to see if the sacrifice is worth it."

Shizuo snorted. "Considering my soulmate will reject me, I don't think it's that big of a loss."

"Stop that!" Mikado snapped. "Kadota really did a number on you, huh? I've been thinking. Your new roommate, he's asexual. Right?"

"Think he said that. Yeah." Shizuo grumbled. Izaya could hear the confusion in his voice.

"So that fits with your soulmate never having sex with you. What if it's not a case of rejection and it's just someone asexual?"

"Given my condition, it'll be a shitty matchup." Shizuo grumbled.

"Any marks appear yet?"

"Nope and they won't." Shizuo snapped.

"Stop it, Shizuo. Anyone would would lucky to have you as a soulmate. Hell, if you were mine I'd take such good care of you. But I know my soulmate and you're right, it sucks."

"Masaomi still pining over the sick girl?"

Mikado blew out a breath. "Yeah. My mark is on my hand, can't miss that. He just doesn't care. I really wish you were my soulmate instead."

"We had fun and you've always been there for me."

"Always will. I'll see if I can find anything else in the archives. Stay off their radar and if you do get marks, keep them hidden. Be careful, Shizuo."

Izaya stayed seated after Mikado had gone and Shizuo remained seated in silence, clearly lost in thought. He didn't have a soulmate yet, so it was possible they could be a pair. But they'd need to touch to find out and he had a feeling Shizuo would now avoid him or try to change rooms.

If Shizuo didn't have his head up his ass, he might've avoided crashing into Izaya coming out of the bathroom. "Shit! Sorry."

"No problem, Shizu-chan. You finished?"

"Uh, yeah. I'm done."

"You're up late. Not taking your sleeping pills?" Izaya asked.

"No. I have an essay to do." Shizuo shrugged. "I'll try and keep it down."

"No need. I have work to do as well. There's some things I can't focus on in the office." Izaya's gaze followed him back to his bed. "What's the essay about?"

"The uniqueness of soulmate marks and the bond link between them. Five pages minimum."

Izaya whistled. "When's it due?"

"Day after tomorrow."

"Good luck."

"Thanks. I'm gonna need it." Shizuo grumbled taking his phone from the shelf. Mikado picked up on the first ring. "Hey, sorry to ring so late. Was hoping you'd talk me through your mark and bond. Need to write an essay on it."

It was a pointless conversation, given he'd finally experience it himself.

It started with an itchy spot. Somewhere on the body, in this case over his heart. Shizuo scratched at his chest. After the itching came the burning that left him feeling almost feverish. The mark itself felt like a knife piercing his skin, carving the outline and filling it in with his blood. The mark could be small, medium or large, depending on the power of the bond, it could be in colour taking on the characteristics of the other other half.

Shizuo took a sleeping pill and an aspirin before the bond was halfway done.

He was late for class, receiving detention for the first time by accident. Mikado glared at him as he handed the slip over in his office. "We spoke yesterday. You slept in? How?"

Shizuo unbuttoned his blazer and then his shirt peeling back the right side. Mikado's eyes widened and his mouth dropped. "Ignore what I said. That's big."

Shizuo had almost fainted from shock at the sight. It started over his heart, covering his right side and moved underneath his waistband. It was a mix of red and black and a beautiful patterned design. "I bumped into Izaya coming out of the bathroom yesterday."

"So it is him." Mikado breathed, lightly trailing his fingers over the mark. "How does the connection feel?"

"Like a live wire. I can feel emotions that aren't mine. I know where he is and what he's doing."

"You've spoken?" Mikado murmured.

"No. I slept in, he was already gone."

"But you know how he feels about it?"

Shizuo sighed. "Possessive."

Mikado whistled stepping back. Shizuo buttoned his shirt back up. "This changes things. You need to talk to him about your condition."

Shizuo groaned. "He's asexual, I need sex. It won't work."

Mikado's gaze was steady. "It has to."

Shizuo sat awkwardly on his bed, cross legged and hugging his pillow. Izaya was on his own bed typing away. Shizuo had been the one to ignore him.

"Uh…"

Izaya paused, eyes flicking up from the screen. "You're ready to talk, Shizu-chan?"

Shizuo held the pillow tighter. "It's not going to work."

"We haven't tried yet."

"There's no point!" Shizuo snapped. "I'm-" Shizuo froze feeling Izaya's emotions lash through him and coil around his heart.

Izaya set his laptop to one side and got off the bed, pushing the screen aside back to the wall. Shizuo's heart was pounding as Izaya put a knee to the bed and climbed over him. "I don't like sex, I don't enjoy it and I feel nothing from it. That doesn't mean I don't enjoy watching it. I do like kissing, hugs and I'm very possessive of what is mine."

Shizuo shivered staring up at Izaya, feeling his soulmate's hands on his face. "But I-"

"Hyper sexuality." Izaya said. "I know. You'll never have my cock inside you, Shizu-chan. But that doesn't mean I reject you. Nothing and no one is taking you from me."

Shizuo felt himself shatter.

Izaya lay on Shizuo's bed with his soulmate breaking down in his arms. Shizuo's emotions were chaotic but easy to understand. Izaya held him, feeling his soulmate's warmth, feeling him realise he wasn't going anywhere and slowly settle. Shizuo's breathing eased and slowed as he went too far and fell asleep.

There were various reactions humans had when faced with him. Mikado stared, hand clasping the door frame, groaned and stepped aside. Izaya closed the door and before he'd even turned around Mikado was speaking.

"Look he warned me you were possessive but Shizuo is a friend. That's all we are now. See I have a soulmate too." Mikado held up his hand. The mark was small put very noticeable.

"I know." Izaya said taking a seat in front of Mikado's desk. "I need you to talk to Masaomi."

Mikado sighed slumping in his seat. "Of course you know my soulmate. Why?"

"Because Shizu-chan needs sex, but he can't hide his mark. I'm not risking it. He trusts you. So, talk to Masaomi get him to give you permission to sleep around and then you're to solely sleep with Shizu-chan but only when I'm present. That way things stay between the three of us."

Mikado frowned staring at him. "Are you setting me up?"

"No, I'm helping you because you were the only one protecting Shizu-chan. I'm sure you've heard of Dotachin's attempt?"

Mikado blew out a breath. "He waited until it was mostly healed before showing me. I offered to be his roommate but they wouldn't separate me and Masaomi."

"What do I need to know?" Izaya asked.

Mikado nodded accepting the change in subject. "Shizuo is submissive. Given his condition it works. You'll be able to help him get off without sex."

"Explain."

"We did tests. To see what he was into and what I could help with whilst he roomed with someone else. Shizuo didn't want to have have sex, he just needed to." Mikado blushed. Izaya said nothing about their relationship and how they clearly liked having sex with one another. "He doesn't like being by himself. If he's in the bathroom then he's getting himself off either watching porn, on the phone or crying."

"On the phone to you?" Izaya asked.

Mikado frowned. "Either me or some app. He doesn't like his family knowing."

Made sense. All of Shizuo's bills were paid by his parents or his model brother.

"Shizuo has a voice kink. He likes orders, he likes being told what to do during sex, he likes using toys, as long as someone is guiding him. The moment he's on his own, it becomes a chore and he hates himself. Outside of sex, Shizuo is a romantic. He likes any excuse to touch, kiss and cuddle. If he didn't have his condition, he probably wouldn't even want sex."

"But does Shizu-chan like to be watched?"

Mikado shrugged. "That I don't know."

"Then I guess we'll find out."

Shizuo blinked seeing Mikado in his dorm room. Izaya had specified no other students, so why was Izaya leading him inside. Mikado sat on his bed. He could feel Izaya's amusement and assurance everything would be alright.

"Shizu-chan, Mikado-kun has spoken with His soulmate. Masaomi is staying with Saki and Mikado is free to do as he likes. He'll be the only one having sex with you from now on. Mikado-kun knows about us and the mark. I'd rather keep that knowledge between the three of us."

Shizuo blinked and nodded slowly. Izaya sat on his own bed. He felt Izaya's need to have him, so he went over and sat between Izaya's legs, letting his soulmate touch his hair. Mikado smiled at him.

"When you need it, I'll be here with your soulmate watching you. Until then, he'll be able to give you what you need." Mikado shrugged. "But it won't be often. They know our connection. So be careful and don't push the beds together. You know they like spot checks."

Shizuo listened as Mikado and Izaya spoke about their plans, his hands curling lightly around Izaya's ankles. He liked the sturdiness it gave him. The soft scratch of Izaya's uniform. His head lolled back and his eyes closed letting his soulmate's voice wash over him.

Mikado stopped talking. Izaya waited for him to continue but Mikado had a finger pressed to his lips, gaze flicking down to Shizuo. With a smile he got off the bed and quietly left, closing the door with a click.

"Shizu-chan?" Izaya asked quietly. His hand stilled and he leaned over to see Shizuo fast asleep, hand wrapped around his ankle. "Shizu-chan, you can't sleep there."

Izaya shuffled awkwardly, removing Shizuo's fingers from his ankle. His soulmate looked so peaceful and without worry. He could feel an ongoing thread of contentment. It was a shame to wake him. Izaya crouched down, his fingers lightly skimming Shizuo's cheek. "Shizu-chan, on the bed."

He moved back ready to catch Shizuo if he fell. Sleepy, his soulmate climbed into his bed. Izaya wasn't complaining. But the school would. He'd silence them, silence everyone. Shizuo smiled as he kissed him, soft, lazy. His. Izaya held his soulmate close.

Shizuo woke early morning seeing light come through the window. All he cared about was Izaya's sleeping face right in front of him. It was like his typical morning wood was no concern. Shizuo smiled lightly tracing his thumb over Izaya's lips, marvelling at the softness. He traced them over and over, letting each cycle sink in that this wasn't a dream.

He wanted to kiss them. "Then do it." Izaya murmured startling him. Shizuo blushed violently. "Well? Surely you're not shy, Shizu-chan." Shizuo ducked his head slowly inching backwards. Izaya grinned and grabbed his wrist. "You are. Even with your reputation?"

Shizuo frowned. "It's different. There's feelings. It's important."

"Good." Izaya answered caressing his cheek. "You're still going to kiss me though."

Shizuo chewed at his lip. Nervous. Damn he was nervous. Not like there was a way to screw things up with a soulmate but knowing his luck he'd manage it. Not like he was a virgin. He'd already given his firsts away to satisfy his illness.

"No. Stop that, Shizu-chan. Kiss me, now."

Shizuo heard the command, the flick of a switch in his brain that cut off the bad feelings. Closing his eyes he inched closer and pressed his lips to Izaya's. Soft, warm and a little dry. Chaste kisses that meant nothing and everything. Did Izaya like heated kisses or was that another anomaly?

Shizuo moved his lips, his fingers sliding between Izaya's. Izaya kissed him back slowly and then Shizuo found himself being rolled beneath his soulmate, Izaya laying flat on top of him, deepening the kiss with his tongue. Shizuo relented letting Izaya have his way. It was nice and sweet, hot and wet. Shizuo could feel himself close to bursting and he didn't think Izaya wanted that mess over his bed.

Izaya backed away slowly, staring him in the eyes before giving him a chaste kiss and getting off the bed. "Time to go. The student council has a meeting."

Shizuo nodded. "Yeah, I need to get to the canteen." First though he had to shower. A long one. His cock was rigid and his balls throbbed. Izaya was perfectly fine. Doubt set in, but Izaya kissed him and told him to come in a commanding voice. Shizuo groaned and headed straight for the shower. Maybe there wouldn't be an problems after all. He could hope.

End
