Disclaimer – I don't own Durarara

Ikebukuro was taken over instantly. Everyone had been going about their day normally, when the invasion commenced. The sunny sky was blotted out by the large disc like shadows and groups vanished in flashes of light. Within moments the invasion was gone and the streets were devoid of humans.

Shizuo woke up on one of the ships. Unfortunately he'd ended up with more of the familiar people and his enemy. They were essentially in a glass box. Izaya glanced his way and Shizuo predictably punched his fist through the glass and watched it shatter. He made the hole wider, until the front caved and everyone could get out.

Except they didn't get far. Alarms blared around them and the door sealed one side, the other side creatures with tentacles rushed in holding a weapon of some sort. Shizuo felt the sting as a bolt hit him. It almost drove him to his knees, but he snapped the charge and tossed it, charging at the alien. He didn't have time to worry about the others. The flea could get them out.

More aliens glided in and something hit Shizuo from behind. It was a sharp shock, that latched onto his back and around his arms binding him. A second shock hit his legs and down he went. His head hit the floor but he was on his side, able to see that the others hadn't escaped. They were either standing with their hands raised or on the floor in dogeza.

He didn't see what happened to the others. The mix of tentacles picked him up and carried him away.

Mikado rose from his dogeza, facing the tentacled alien standing over him. He watched the door shut and their strongest player was taken away. One of the tentacles slid across his throat and he winced feeling something sting. But he could now understand the alien. A translator?

"Greetings human. Stand. You will be tested."

Mikado frowned looking to Izaya. The informant was quiet. He too had been hit with a translator. Mikado stood and waited.

"Tested for what?" Karisawa asked breaking their silence.

"Compatibility." The alien spoke.

"Ooh, like breeding? You want to see if we can have alien babies?"

Mikado blanched. He hoped not.

"Correct. We require new blood."

"Yep yep, I see." Karisawa nodded. "So apart from me, everyone is a male. Don't you need lady parts to carry a baby?"

Mikado felt sick. Kadota had grabbed onto Karisawa's arm and squeezed, but she wouldn't stop talking.

"Incorrect. Gender does not matter. You will be tested. Your results will decide if you are to be male, female or released."

Karisawa nodded. "So you're saying I could be a male alien? What about the guy you just took?"

"Possibly. Decided, no need for testing."

Karisawa leaned forward. "So? Are you going to release him? What's the result?"

"Female."

Mikado closed his eyes and slumped. Shizuo would be a female alien, so what hope did the rest of them have? If he was lucky they'd let him go.

Shizuo woke in a tank, submerged in water with restraints around his wrists, ankles and throat, keeping him well away from anything breakable. He could see outside the tank, but his concern was below.

His body wasn't responding to his anger. It wasn't responding to anything, except the strange heat pulsing through his body. He could breath, easily, so it probably wasn't water. Something touched his leg, sliding up his leg. Shizuo moaned as the tentacle wrapped around him, holding him in place. It felt like home.

Shizuo willed his body to move, crossing his legs to trap the tentacle against his body, his hips rocking to gain friction. "Please." He breathed. "Touch me." His wish was granted with more tentacles rising, wrapping themselves around his body. Shizuo shivered, clinging to his favourite. He jolted at the first intrusion, but his mouth was feeling so empty, latching onto the first tentacle. Shizuo licked and sucked needing something.

He was pulled away from his favourite, a smaller much more flexible tentacle coiling between his thighs and around his throat, before pressing between him lips. Shizuo moaned around it, opening his mouth and flicking out his tongue. The thing went deep and Shizuo writhed, especially from the millions of little kisses he could feel fluttering in his mouth. He'd never felt so loved.

More tentacles joined, slipping into his ass or around his cock. Shizuo almost came as a really thin one pressed inside his cock. His head tilted back, urging them all deeper. The one in his mouth was leaking. Shizuo focused on that one, licking and sucking where he could, his tongue meeting the little ones everywhere. He swallowed the thick liquid down, more and more of it. His body was burning and that was the only thing calming it down. His hips rocked and he gulped greedily.

The smaller tentacles spread him open, stroked him and kept him painfully hard. They set his body on fire and kept him guessing where they'd touch him next. Shizuo was a mess, but he was home and he loved it. The smaller tentacles retreated and Shizuo whined for them swallowing more of the liquid.

But there was something else flying up, something that looked like an octopus latched itself between his legs and Shizuo felt it's large pulsing cock push inside. It was huge and fast, Shizuo's eyes rolled and for a moment he couldn't focus. The other tentacles squeezed and pulled, the tentacle in his mouth squirted again and Shizuo went back to sucking.

He was kept spread as he was fucked, his head back so he couldn't see how deep it was going. He could only feel it. His body felt like it was breaking and it felt so good. The cock was lodged inside him and Shizuo almost passed out as his ass was flooded. He felt bloated and it wasn't enough. The cock pressed even deeper and the pain made him black out, the tentacles held him, caressing him soothingly. Shizuo screamed as the thing pressed into him completely and then it was gone. He got to swallow the liquid once more before the tentacles snapped his restraints and guided him from the tank.

One of the aliens outside touched him, a sharp pain sparking at his throat. "Welcome home, princess. We've been searching for you."

Shizuo looked mournfully to the tank. "I want more."

"We have suitors for you to choose from."

Shizuo pressed up against the glass. "Put me back. I'm not done."

"Princess…"

"I'm not done." Shizuo snapped, staggering to the side.

They let him back into the tank, where the tentacles came to play.

"Why are we still here?" Mikado heard one of the aliens say. "We've already completed our objective."

"They may have their uses."

"This is a waste of time."

Mikado frowned. The alien sounded like a teenager. They'd been separated, all of them into unique rooms. Mikado had his strength tested, his body examined and his mind tested.

"This one isn't fully grown." The teenage alien reported.

"Sometimes that's a good thing." The other alien remarked. "I think we should keep him, it will make the princess happy."

Princess? Mikado hadn't expected there to be alien royalty.

"According to earth laws, this human is of legal age."

Mikado's eyes widened.

"Fine." The teenager said gliding in front of him. "We will test your compatibility for our princess."

Mikado flinched as tentacles latched onto him, they left a slickness in their path and he was already naked. There was a smell in the room, a strange scent that made his cock hard and aching. And then all too quickly it was gone, like a switch shut off. "No!" Mikado moaned. "I need-"

"This one is compatible. Prepare him for the princess."

"Wait!"

Izaya observed the aliens and in turn they did the same. After they'd taken Shizuo, they'd split them all up into separate rooms. They hadn't yet gotten around to doing any of their tests on him. A light above the door buzzed and slid open to reveal yet another alien.

"We have a problem." The newcomer reported. "The doctor miscalculated. We need to leave now or the tank will empty before we get home."

"Dump the humans, we're leaving." The biggest alien with yellow tips commanded.

"We can't." The newcomer whined. A teenager. "The princess has already claimed her mates. We don't have them."

The tipped alien tensed. "How many?"

"Two claimed and one rejected. We have one however he is barely matured. He won't be enough to sustain the princess. The other one doesn't appear to be on the ship. We've put out a scan for the other ships. The humans do not want to cooperate."

"Then tell them the truth. Without her mates, the princess will die and her mates will die immediately after. The doctor miscalculated, we should've arrived when she hit puberty. Skip the tests, test for compatibility. If it's a match, toss them in and hope for the best."

"Yes, leader." The teenager turned and made to glide out.

"Wait. Will the princess's first mate be able to sustain her enough?"

"The princess will kill him. He's not matured enough." The teenager whined.

"Will he survive a conversion?"

"Yes, but the tank would empty quicker."

"Do it." The general twitched. "What's the name of the princess's first mate?"

"Mikado Ryugamine. He is content with any decision to save the princess."

"Mates usually have connections to one another. Scan anyone connected to this Mikado."

"Yes, leader." The teenager left.

The leader turned to the other alien in the room. "Take over here. I'm going below." Before Izaya's eyes the leader with the yellow tipped tentacles shifted and moulded into human shape. He tried not to let his reaction show. It was almost a carbon copy of Shizuo. "Keep the princess alive." The deeper tones spoke. "Have the doctor on standby. If my sister dies, he's a traitor."

"Yes leader."

Izaya didn't move, didn't dare say a word. He'd heard and seen enough. The aliens had come for their princess. Judging by the family resemblance that was Shizuo. Shizuo who was currently at risk of dying and taking his mates with him. Mikado was one and he would be the rejected one. If Shizuo died, so did he.

Shizuo was at home in the tank. It was only a small piece of her home-world, enough to sustain her until they got home. She felt light, relaxed. The tank was a warm cocoon. The tentacles were resting, but that was okay. They'd brought her mate. They'd talked, cuddled and then they'd taken him away.

Mikado was returned to her, older, stronger. They'd converted him. Shizuo kissed him, holding him close. Mikado kissed her back. "They'll find him."

Shizuo hoped so. The distance between the planets was too big. She wouldn't survive the separation. Then there was her rejected mate. Izaya. She didn't want to think about him, didn't want to be near someone that didn't want her. The rejection marker was still there, the only scar visible on her skin.

Mikado sensed her distress, now that they were linked and rubbed at her arm. "I can keep him from you."

So she relaxed. It was all she needed, her temporary home and her mate. Once she was back on her planet, she could be in her real skin.

Masaomi struggled against the man holding him. He'd thought it was Shizuo whisking him away from the hospital after yet another nasty visit with Saki. It wasn't. The guy looked him up and down, scanned him like he was an item in a supermarket and now he was on a spaceship. An alien spaceship and the aliens were mostly tentacles.

"Hey! Put me down."

The man ignored him dragging him through the ship and into a room with a tank. Masaomi frowned seeing Shizuo and Mikado inside.

"Seriously? You could've just asked. Damn it."

The alien tossed him in the tank. He came up coughing and spluttering before realising it wasn't water. "What the fuck?"

Down below the surface, Shizuo and Mikado were cuddling. Taking a deep breath he swam down to join them. Mikado took his hand and Shizuo wrapped an arm around his waist.

"You can breath. It's not water." Shizuo said. "I'm sorry. We're going home."

Masaomi took a deep breath. "That's fine. Saki and I were already done. So where is home?" Masaomi sighed. "This is really relaxing."

"You're not bothered I'm an alien?" Shizuo asked with a quiet grumble.

Masaomi snorted. "More relieved we can be together without interference. We can talk later if need be." Masaomi flinched as something slimy moved by his head. "What the-"

Mikado grabbed what looked like a tentacle and pressed the appendage to Shizuo's lips. "What's that?" He asked voice slightly shrill.

"Shizuo needs it to stay alive until we get to her planet. This tank used to be overflowing. Now that you're here, we can leave. We should just about make it."

Masaomi frowned. "I'm so confused."

The ship was moving. Izaya felt the floor move before stabilising. He made it to a window seeing nothing but space. They hadn't been scanned, they'd been left in a room, effectively kidnapped. Izaya understood their princess's life was in danger. But they could've given them a choice on getting off the ship.

The door opened and in came yellow tips, apparently staying as Shizuo's doppelgänger. "Urgency has become an inconvenience. I am general Tsugaru of planet Octopoda. You humans have been caught up in the rescue mission for our princess. She is currently on…life support. The other ships have time to unload their passengers. We do not. This ship is already on its way home. For the time being you will be our guests. Think of it as a…vacation. If you would like to stay you will be allowed, if not, a ship will return you to your planet."

"Your uh princess. She gonna be alright?" Izaya heard the question from behind him.

"We hope so. She has her two mates, they will sustain her until we get her home."

"So the compatibility thing was to see if we were the princess's mates?" Another one behind him. Izaya was regretting standing front and centre.

"Correct. There is no need for tests. Feel free to move around the ship and ask if you need anything. If you'll excuse me." Tsugaru left with the door wide open.

"Oh, vacation. That's cool."

Izaya sighed and left the room.

Izaya explored the ship, finding the most heavily guarded areas, the engine room and control deck, as well as the tank room. The aliens were welcoming, but focused on their task.

He wasn't expecting to run into a familiar face. Masaomi was holding a picnic basket of food. He paused when their eyes met. "Why are you here?"

"I could ask you the same thing, Masaomi-kun." Izaya answered.

"I'm getting food."

"I'm on vacation, seems like Tsugaru feels bad for not dropping us off."

Masaomi scowled. "He had his reasons. I can't believe they let you on board in the first place. This is the last thing she needs."

Ah. Now it made sense. "What happened to Saki?" Izaya asked.

"She decided to play the damsel for someone else." Masaomi shrugged. "I wouldn't advise telling anyone your connection."

"So I hear. How is Shizu-chan?"

"Sleeping. It's going to be touch and go." Masaomi answered already walking away.

Shizuo was docile. The tank was reduced to a deep swimming pool. She lay between her mates staring at the diminishing liquid. Once again she was left wondering if she would make it.

"Princess." Shizuo moved from between her sleeping mates and over to the glass where her family waited. Tsugaru. Her oldest brother that hadn't wanted her to go. She'd been seven when they separated.

"Brother." Shizuo smiled. He was using her humanoid form. "Will we make it? The tank is running low."

"At this point we can only hope. Princess, we need to speed things up. You need to encourage your mates to breed you."

"Masaomi is still human."

"We'll need to convert him."

"That's his choice." Shizuo frowned. "But that means…"

"The tank will drain." Her brother confirmed. "Once your mate is converted, we'll force your heat. It's the only time the liquid isn't needed. Should you become pregnant, you'll produce your own and that will keep you alive."

Shizuo hung her head and slunk back to her mates. Masaomi kissed her forehead. "Whatever you need."

Masaomi was converted. Shizuo risked poking a finger out of the liquid and felt the revulsion hit her hard. She recoiled and pressed beneath the kiddy pool of liquid. "It'll be alright." Masaomi held up the injector they'd been given. They each had one. Shizuo pressed the button, feeling heat spread through her body. Mikado and Masaomi did the same.

Heat cycles were rough as humans but they were consuming as Octopodas. Shizuo felt the need swallow her whole. Her body throbbed.

Mikado lay on his back, lifting her onto his hips, his eyes flashed such a pretty blue and his intentions were wicked. Masaomi was behind her, touching her chest. Flat for now. Her body was so sensitive to touch. Mikado guided her onto his cock and pulled her down onto his length. It was thick and ribbed. That would change too. Everything would change once they reached home.

Masaomi grabbed her short hair and tugged her head back, his cock slapping against her cheek. Shizuo opened her mouth, twisting to take it. She sucked and hollowed her cheeks. Masaomi had no changes so far.

Her hips rolled as she rode Mikado hard. This was all she needed. The scar across her chest twinged but she guessed that was whatever was left of a non existent link breaking through separation.

The aliens were trusting and didn't seem to know what keeping secrets meant. They answered all questions they were asked. The ship was close to landing. Given Shizuo's strength and the tentacles, it was surprising how scenic the planet was. It looked like rainbow glass, rocks and crystal water.

"We made it." One of the aliens patted another, whilst the humans stared out of the window. "Leader, are we going to the palace?"

"No. Stop at the mating pool. Empty the tank in there." The general didn't stop, back in his tentacle form.

"An heir already?" The same alien said.

"They didn't have a choice."

The ship glided and then stopped. The mating pool was more like a crystallised ocean. The ship was low enough to hear a splash but not enough to see anything.

Shizuo yelped as she and her mates were ejected from the ship and into the ocean below. She felt the warmth embrace her, embrace her mates. Here she'd stay until the changes were complete. Masaomi and Mikado took her hands and pressed against her body.

"Our home is beautiful." Masaomi said running a hand slowly over her belly and down between her legs. Mikado joined him, their fingers inside her. Damn she was sore and still aching for their cocks.

The throne room looked fragile. The throne was empty and the seats next to it. The humans gawked at everything, complaining their phone batteries had died. The general stood before the dais in front of the throne.

"There are two rules. Stay out of the water unless you wish to become one of us. Stay away from the throne or anywhere marked with this symbol."

"Why?"

"Hey do you have a charger?"

"The areas with this symbol can only be used or entered by the princess or her mates. Anyone else will die." The general said. "As for chargers, see the engineer or the doctor. Ask any of the Octapodas and they'll guide you. There will be a ship leaving in twenty four earth hours should you wish to return home."

The throne room vacated. No security since it wasn't needed. Izaya loved to the dais and sat in the throne. He wondered through the palace and into the sleeping chambers and then he waited in plain sight as he had been.

Shizuo returned to the palace by herself. Her mates were deep under water adjusting to their change. She wasn't pregnant, but the changes to her body had already happened. Her hair was pointlessly long, her breasts well endowed and her cock had remained, even if she was now mainly all lady parts. There was nothing she could do about the hair, unless she wanted short tentacles.

It was different rules for the male and female. The female were the rulers, the minority and the most valued. They were the strongest. To have a woman of their species, you either were chosen or had to best the female. All women had long hair, their tentacles were the length of their hair, unlike the males.

Shizuo brushed her hair behind her ears, hating how it trailed behind her like a wedding dress. She'd have to style it. For now, she wanted to sleep. In her bed and when she woke up, hopefully her mates were finished with their transformation and they could continue where they left off.

Her bed chambers were modelled on an earth bedroom, but more regal, princess type. Shizuo sighed gravitating towards the four poster bed, she pulled back the curtains and fell in, scream muffled as she found the bed occupied and a sharp blade at her throat.

The scar at her chest throbbed, even as her soul cried out. Her third mate had come along for the ride. "Now isn't a good time, flea."

"Oh I disagree, Shizu-chan."

Shizuo frowned realising it wasn't a knife at her throat. "What the-"

"Pay attention." Izaya chided pushing her into the mattress with his weight. "You have some explaining to do, Shizu-chan."

"None of your business, flea." Shizuo snapped.

"You still don't realise do you?" Izaya smirked. Shizuo stilled as his fingers traced her spine. Her naked spine. She was still in her heat.

"Izaya, stop! Pheromones. You're not-"

"You're in heat. Each species has its own mating ritual. Did you know there's a race where the male maims the female and waits nine years." Shizuo frowned but Izaya was still talking. "It comes from the myth about cats having nine lives. The nine years abstinence represents a lifetime without their mate. We still had two to go."

Shizuo felt her mind blank. "What? You rejected me."

"I claimed you." Izaya corrected. "You ran, took children as your mates." Shizuo hissed feeling something slice into her skin. "You only had to wait two more years. Too late now. I'll have to lose the two lives."

Shizuo frowned. "What are you-"

"Say yes, Shizu-chan." Izaya warned. "You brought this on yourself."

Shizuo jolted as Izaya's fingers touched her private places. "Yes." She moaned feeling the scar throb. She lifted her head seeing Izaya's eyes flash red and swirl. Izaya's hand was black with claws. "What-"

Shizuo was held face down, ass up. One moment Izaya was touching her and the next it felt like there was an animal on her back. She screamed as it mounted her and stuck its cock inside her. The beast rode her hard and when he thought it was over, the beast's cock spiked lodging inside her and filling her up until it hurt.

Shizuo slumped looking over her shoulder as the black cat like creature with red eyes. Izaya. Behind him were seven tails, long and wicked looking. She'd misunderstood. She'd never been rejected. She was just clueless when it came to other races.

Izaya didn't have tentacles but his tails were just as flexible. Shizuo found herself with one or two in her mouth, whilst her mate fucked her in beast form. Now that she understood, the broken bond she thought she had, was thick solid and almost overlapped the other two.

Since her heat was calming down, she was sure she was very much pregnant. Izaya filled her with another load, finally pulling from her body. The beast nipped at her shoulder and pawed her back before rolling away and transforming back to lay beside her.

"You have claws." She said stupidly.

"Observant." Izaya murmured eyes closed.

"The two lives…"

"Already gone. It's the price for impatience, Shizu-chan."

Shizuo tested her head on Izaya's chest and took his hand. "You got me pregnant. Don't fight."

"No promises." Izaya's claws stroked through her hair.

She'd take it.

End
