Summary:- Some things were best left alone.

Contrary to belief genies weren't bound to grant wishes. At least the one Mikado was currently facing didn't. The teen had thought he'd been lucky striking gold in an old warehouse. Most likely the bottle had been discarded because the genie inside was nothing short of an asshole.

And now he couldn't get the entity back in the bottle. The genie or jinn hovered against his desk ringed fingers brushing gently against his keyboard. He looked human enough black hair, slight frame and dressed in full black instead of puffy pants like in the stories. The only thing difference from a human were the eyes that glowed a strange red and the superiority complex tweaking the jinn's lips.

"Mikado-kun, I'm waiting." The Jinn purred. Izaya was its name. Izaya the genie that wouldn't grant his wishes.

Mikado stared calmly at the supernatural creature mulling its words over. "You won't grant my wishes? You owe me three."

Izaya laughed soft mocking. "For rubbing a bottle? This isn't a fairy tale, Mikado-kun. Why should I give you something and have nothing in return?"

The blue eyed teen frowned. "What do you want?"

Izaya's face lit up. "I'm bored in my bottle all alone. I want a sacrifice."

"A companion? You're lonely?" Mikado asked masking his surprise. "I can be your friend."

The jinn shrugged. "You could but then you wouldn't get your wishes. No, I want you to give me the most interesting human you know."

Mikado blinked. "What? What will you do with them?"

Izaya only grinned moving in front of him. "That's for me to know and them to find out. Fill the bottle with liquid and have your chosen drink from it."

Mikado looked at the bottle on the floor. "Drink directly?"

"Is that a problem?" Izaya smirked caressing his cheek.

Mikado swallowed cheeks heating. "Won't you drown?"

"Mikado-kun," The jinn sighed "I thought you were a smart little human. I'm not actually in the bottle. The bottle is a portal. Remember if you want your wishes there's a price to be paid." Izaya pressed their lips together vanishing in a wisp of smoke.

Mikado already knew who the most interesting human was because he was already dating him. It had been his biggest challenge getting the infamous fortissimo to become his boyfriend. Shizuo despite being angry, grumpy and violent, was surprisingly shy and gentle.

The teen enjoyed their companionship, remembering everything they'd done together. Grabbing a funnel he placed it in the mouth of the bottle and carefully poured the strawberry milkshake he'd made inside.

Shizuo had taken ages to get into bed, even longer to actually take his virginity. I don't want to hurt you was his boyfriend's favourite phrase. Mikado sighed placing the empty blender down and tossing the funnel in the sink.

The question was how to get the fortissimo to drink it when the bottle itself looked like an extravagant perfume bottle. No sooner had the thought formed, the bottle ripples shaping itself into a carton of milk.

Mikado stuck it in the fridge and tried not to think about his betrayal. If he felt like it he could always wish his boyfriend back. Instead he grabbed his notebook and set to work deciding his three wishes. Izaya was a tricky one. He needed to get it right.

Shizuo came home early a tear in his bartender uniform. Lucky for him, not so lucky for the one that had done it. Mikado watched as his boyfriend went straight to the fridge in search of comfort snacks and dairy goodness.

His heart quickened staring at the transformed carton lifted to Shizuo's lips. An objection sprang in his mind but not one that left his mouth. The fortissimo noticed him staring and glanced over. "What are you so happy about?"

Mikado continued smiling. "I'm thinking about what you're going to do to me." He whispered blushing. Shizuo coughed putting the carton back in the fridge. Hopefully he'd drank enough.

"That's-" his boyfriend blushed flustered. "You shouldn't talk about that stuff."

Mikado nodded smiling apologetically. "You're right. Sorry Shizuo-san." Embracing his rarity the teen sighed head pressed against Shizuo's broad chest.

Strong arms wrapped around him carefully and awkward as usual. "D-do you want dinner?"

Mikado shook his head taking his boyfriend's hand and leading him to the bedroom. "I'd rather have you first." After all who knew how long they had left together.

x-x-x

Mikado rolled his hips sliding himself down on Shizuo's arousal. Riding the fortissimo was the only way he could go at the pace he desired. He wanted excitement not to be treated like a precious thing. Shizuo moaned not touching him, not doing anything. At least it didn't look like it. But Mikado could see the strain and concentration. His boyfriend was holding back. Whilst part of him was flattered the other part of him was insulted.

"Shizuo-san." The teen cried slamming down. "Fuck me, please."

Shizuo hesitantly touched his hip. Mikado clutched the touch pressing it against his flesh. His hips moved more reckless riding Shizuo until the grip tightened a little to slow him down.

The teen moaned collapsing onto blond. Shizuo gently pulled out of him holding him in a gentle embrace. Mikado sighed kissing his boyfriend and escaping to the shower.

x-x-x

Shizuo watched his young lover climb off the bed and towards the bathroom. If he'd guessed right the teen was annoyed. Why he didn't know. He'd been gentle. He'd done his best to show how much he loved Mikado.

Grumbling to himself the blond pulled on his pants and stormed into the kitchen where he'd left his cigarettes. Whilst he was at it he took the remainder of the milk in the carton with him.

Leaning against the window Shizuo leaned against the balcony lighting up and taking a drag. Relationships were hard work and then there were people pissing him off wrecking his uniforms. Taking a swig he drained the rest of the carton. Shizuo didn't know where Mikado had brought it from but he wanted more.

It was a good thing he smoked outside. For one he wasn't turning their ceiling yellow. For another he was protecting Mikado's lungs. Shizuo sighed flicking a bit of ash away. Really he should stop altogether. Especially with it the smoke seeping into his clothes. Shizuo slid the window closed waving a hand to dismiss it.

The smoke engulfed him. Quickly Shizuo stuffed out his cigarette but this smoke wasn't coming from the discarded cigarette. It was coming from the milk carton. Shizuo grabbed it feeling something cold and smooth. Picking it up he narrowed his gaze. He was holding a bottle. A red and black one that curved like delicate glass. It reminded him of those expensive bottles Kasuka advertised.

Mikado wrapped a towel around his waist smiling as he decided to let his boyfriend pamper him a bit. With his hair dripping wet the teen went back to the bedroom. "Shizuo-san, can you-"

But the fortissimo wasn't there. Mikado swallowed stepping into their small kitchen but the smell of Shizuo's cooking didn't greet him. Maybe a smoke then. But the balcony was empty except from a crushed cigarette and the jinn's bottle.

Sliding open the door Mikado grabbed the bottle and rubbed it. Smoke rose around him and then there was the jinn leaning against him. Mikado frowned seeing this time Izaya was half naked wearing only a snug pair of trunks.

"Mikado-kun," The jinn purred circling him eyes aglow. "Did you call me for your first wish?"

Mikado balled his fist. "You took Shizuo-san."

"No, you gave him to me. He quite enjoys his new home. I quite enjoy him."

Mikado shook his head refusing to fall for the taunt. "You can't have. It's only-"

"Time moves very differently. What is mere minutes for you is months for me."

Mikado gulped. "M-months?"

Izaya grinned. "Months. Four to be precise."

The teen slumped. "I know what I want to wish for."

The jinn smirked "go ahead."

"I wish I had Shizuo-san back." Mikado trembled the bottle threatening to fall.

"I can't do that." Izaya shrugged.

"Why not?" Mikado asked.

"The sacrifice can't be returned. You should've read the small print."

Mikado twisted to meet Izaya's gaze. "What small print?"

The jinn touched the bottle sliding his fingers over the smooth glass and guiding his gaze to the bottom where gold text rippled. "Here." Izaya whispered.

"I didn't-"

"No one ever does. Call me when you've decided on your first wish." Izaya grinned vanishing in a wisp of smoke.

Shizuo found himself in a large bed that could only be possible in his dreams. His body sank into the soft pillows gathered around him, the covers were a warm hug. He'd never felt anything like it.

"Ah you're awake." A voice chimed at his side. "I'm Izaya."

Shizuo fought to pull himself from the comforting warmth. The stranger grinned sitting on the edge of the bed. "Shizuo Heiwajima." He found himself answering. "Where am I?"

Izaya smiled following his gaze. It was small but felt big, like a room with everything crammed into it. "My Home and now yours."

Shizuo sat up wide awake at that. "What?"

"I'm a jinn. I live in a bottle. For me to grant wishes there has to be a sacrifice. You're that sacrifice." Shizuo shook his head in denial. "My current master is Mikado-kun."

Mikado. Shizuo felt sick. His boyfriend had thrown him away for wishes? "But he'll wish me back, right?"

"No." Izaya sighed. "A sacrifice can't be returned. Mikado-kun knew that. Sorry Shizu-chan, you're mine now."

Shizuo said nothing his heart shattered by his boyfriend's betrayal. Izaya sat watching him the only one with him.

"How long has it been?" Shizuo asked. He hadn't needed to eat or use the toilet. He still smelt fresh from his magic shower.

"A few days now." Izaya told him. "Your mortal form is frozen in time. You won't age, you won't need any of a human's necessities."

Shizuo nodded curled into a ball. "What do you do then?"

Izaya shrugged "play chess and other games, talk to myself and sleep. It's not really sleep, it's just- never mind. You're here now. My partner in eternity."

Shizuo looked around. He couldn't pick out anything, it was like a hazy mirage. The bed and Izaya were the only things clear. "Eternity?"

"Yeah. Don't worry time passes quickly here. We've already wasted a day."

Shizuo blanched. By the time he got out everyone he cared about would be gone. Not that Mikado really cared about him.

x-x-x

One month Izaya had told him adding a little timepiece to the side of the bed. When a day passed it chimed. Mikado's betrayal was still raw.

"How long do you humans sulk for?" Izaya asked sitting next to him on the bed. "You all take betrayal so hard but deep down you know it's coming."

Shizuo sighed glancing at the jinn. "You wouldn't understand."

"Try me." Izaya grinned holding up a book. "I've studied your history, everything that makes you humans tick. I made a probability chart of what a human will wish for."

Shizuo felt his lips twitch. "You must have been bored."

"You try being isolated for a millennia." Izaya scowled. "And now the one human I get acts like he's dying."

"Sorry." Shizuo sighed.

"You loved him, he betrayed you." Izaya shrugged. "Why don't you let me make it all better?"

Shizuo sighed shaking his head. "I can't."

x-x-x

Two months later Shizuo was bored and ready to move on. Izaya couldn't be happier dragging him around their confined space. Shizuo tried not to step on any books or game pieces. From all the possessions it looked like Izaya had tried dissecting humanity.

He sucked at chess and couldn't understand the moves even when Izaya was so patiently reaching him. "It's okay. We've got all the time in the world."

"I can't do this." Shizuo cursed. "I'm not smart."

"I've had a lot of time to practice." Izaya shrugged. "Why don't we do something you'll enjoy?"

Shizuo followed Izaya curiously. "What's that?"

"Sex." Izaya grinned.

Shizuo faltered. "I don't-"

"I'll be topping." Izaya took his hand.

"Oh." Shizuo nodded. That meant he didn't need to be careful. "Okay."

x-x-x

Shizuo cried out clutching Izaya. The jinn thrust inside harder and faster than he'd thought possible. He still attempted learning but ultimately they reverted to sex, their slick bodies against one another. No shower. No matter how many times Izaya came inside him his body remained fresh with no need of a shower.

"Shizu-chan." Izaya whispered going still. "Looks like Mikado-kun wants to make his first wish. I'll be back soon."

Shizuo nodded trembling when Izaya pulled out and kissed his hair. Already he could feel the magic of their home cleansing him. "Hurry back." He murmured.

x-x-x

Shizuo had been with Izaya for four months and Izaya had been gone for coming up to two. Something had happened or he'd been abandoned. Shizuo shook himself. He knew how Izaya felt locked up alone. Izaya had fought loneliness for a millennia. He was barely coping with two months.

"Shizu-chan, I'm home." Izaya called arriving in a cloud of smoke. Shizuo hopped up from the bed and ran to greet his lover. "Did you miss me?"

"Where the hell have you been for two months?"

"Ah. I told you time works differently."

Shizuo crossed his arms. "Next time take me with you."

"Even if you have to see Mikado-kun?"

Shizuo flinched. "...yeah."

Izaya embraced him. "My Shizu-chan missed me. Why don't I make it up to you?"

Shizuo smiled leading Izaya to their bed.
