Welcome to locked~! This won't be long but it's gonna be amusing for me to write and my plunnies refused to leave me alone on it... and by not long I mean 20 chapters or so?

Warnings: Fluff, AU, Izuo, smut, lemons, a little OOC'ness, language(fuck yeah!) and mpreg. Yeah, Mpreg. Hate that then GTFO this page, seriously.

And if you're gonna flame or say I write 'mediocre badfics'(you know who the fuck you are) then let me tell you, if you want to say my fics suck or are bad go look up some actually bad ones and get back to me. I'm sick of flamers and I'm at the point I want to turn off anonymous reviewers so I don't have to read the shit people say. It's hurtful and cruel to tell people they suck just because your in a bad mood or because you didn't like it or it wasn't your cup of tea or you 'felt like flaming'. If you hate my fics STOP READING THEM FOR THE LOVE OF GOD, I AM NOT FORCING YOU. YOU ARE FREE TO LEAVE THE PAGE AT ANY TIME. But don't flame. Anon flames are deleted. Signed flames will be sent a pm asking what their definition of a 'good' fic is if mine are so bad or told to look up some actually bad fics, because trust me, while I will never claim to have the best, I know for a fact I'm not even close to the worst.

Ahem. Rant complete.
Disclaimer: I do not own Durarara! or any of it's characters. I do not own that story concept either. I do, however, own this story and if I find people publishing my shit they can expect to be reported for theft. The concepts for my fanfictions ARE mine and I will protect them. Thanks.


In this world everyone has a key or a lock, you wear yours over your heart, always. Whoevers key and lock match up were meant to be. 50% have keys, 50% have locks... no one knows who has what until they show it to the person they hope to unlock... It's assigned at random I hear, at birth. Your parents know but your siblings don't unless you tell them. If you have a key you dominate and if you have a lock it means you're submissive. Everyone thinks I have a key… why wouldn't they though, I'm certainly strong, dominant some would say… but I have a lock and I can't change it. No one is sure why we're born with them, they're organic, part of us. You can't marry if your key and lock don't match, you can't even have sex. Not because it's not legal… well, the marriage part is, but nothing works unless you're unlocked… or unlocking someone. We can be attracted to others, sure, but they said before the locks and keys were made part of us it was chaotic… people would be with anyone and everyone, marry, divorce, marry again… divorce rates don't exist now. You still date, you wouldn't try to unlock someone you just met… you wouldn't even show them what you have. I'm not sure how keys stay hidden, but locks are pretty flat… at any rate the locks and keys simplified things. You can only be with one person in your life, the person you match with because we've been hardwired with the locks to need to be unlocked every time you get intimate. You relock afterwards, both sides.

"Hey," I call out to my boss and he nods.
"Hey. You're early,"
"So are you," I point out with a sigh, putting out my smoke. Tom just laughs and smiles at me.
"Yeah, guess I am. Are we ready to head off then?" He asks with a gentle look and nod. I often contemplated seeing if Tom is it… he could be, but then he confessed to me once that he had a lock. I've never told anyone that fact, if someone tells you that it's in confidence that you won't tell anyone… except I haven't told anyone what I am either because Tom prefers women… and I like men. This day… I hope Izaya doesn't bother me on this day.


Ahh, this world is so perfect! I have every excuse to not sleep with anyone, to never get intimate. I don't know what I would do if I lived in the old system… sex was a good way to spread diseases, ones that no longer exist at that. But like this I can claim to love all of them, all my humans… and whoever my key matches is a monster… a monster like Shizuo even, but there is no way Shizuo has a lock. The thought of a man like him submissive to anyone is laughable. Of course it's obvious that I have key. I frown a little as I look down at my chest. My skin is flawless, smooth and perfect except there. The rough outline, but I can call it out any time I want. One hand on each side and concentrate… the flesh rises out, and then appears, like it's on a string. The key hangs down, it's lower than locks when it's called out… and you can move them. They separate if you call the key out, the lock is just always there… waiting for a key. I've only ever seen one lock, Kururi's. Mairu has a key like I do though, that makes me happy. I sigh and let the key sink back into me, hiding itself from view except for a little bump over my heart. I pull on my shirt for the day and smile a little. It's Wednesday, so today I'm bothering that monster… Shizuo… I'm tempted to try, to at least peek and make sure he has a key… if he had a lock after all… ah, but I'm thinking too much aren't I?

"I'm going out today Namie-chan~!" I sing, and she scowls at me. I can usually guess if people are a lock or a key, but Namie surprised me. I tried with her once you know, I figured she wouldn't be too bad if I had to with someone, but she has a key too. I nearly died laughing at that and I have to wonder about the poor bastard she unlocks. I contemplate whether to take the train or just walk, though this time of day the train is uncomfortable. Walking it is then and I can walk fast. I live just inside Shinjuku anyways, Ikebukuro isn't too far and I'm deep inside the neighborhood before I can say Dullahan~! Speaking of which apparently she hasn't got a lock or a key. Shinra says he doesn't care, he'll never love another but her but he didn't tell me what he has. No one does, people ask me to find out what others have instead sometimes though. Saves time right? You end up not dating people who have keys if you have a key and vice versa with locks.

"Kida-kun~! Oh my what a lovely friend you have here~!" I approach the blonde from behind, my arms going up, one around Masaomi and the other round his friend Mikado. I nearly laugh when I feel them both go stiff as boards.
"I-Izaya-san, what are you doing?" Mikado asks cautiously and I have to smirk.
"Oh~? Can't I just say hi and hope you have a nice day~?" I tease.
"No. Now stop touching us," Kida growls. I chuckle a little, I do wish Kida was a key but he's a lock… had I known that I might have sent someone other than Saki after him since she was a lock too.

"Aw, such love Kida-kun~! Ryugamine kun here is much friendlier~" I muse with a grin. My hand moves right over his heart sending a small shiver down the boys spine. The area is very sensitive on all of us and it's considered rude to touch it intentionally but my own curiosity demands to know if he's really a lock like I pinned him for.

"G-get off me…"
"Don't touch him!" My hands fly up innocently as I can.
"Oops~! My bad~!" I tease, but I have what I want. A lock feels different from a key and Mikado is definitely a key.
"See you boys tomorrow~! Ahahaha! Just kidding!" I cheer before walking off. I wonder if they've tried unlocking each other. Hmm, I wonder who I can tease now~?

"IZAAAAAAYAAAA-KUUUN. I knew I smelled you! Haven't I told you to stay the hell out of 'Bukuro?" Oh damn…
"Shizu-chan! Why… have you? My memory is a bit hazy when you speak to me, mainly because you have nothing important to say but hey, what can you do~?" My legs are tensed, ready to spring away if I need to.

"I'm gonna kill you!" He roars, yes, Shizuo is definitely a key. I run for it, already jumping down the nearest alley as I hear him roar and chase after me. He's down here too but I know the alleys better, and soon I turn and throw a knife. He dodges of course but it cuts open his shirt and along his chest. He hisses, I know I grazed his… hang on that's not right. The skin over his heart doesn't bump out slightly over the hidden key, it sinks in and his keyhole is a very different shape from Kururi's but I hear each lock is different and as unique as the person… and only one key will ever match up.

"You're a lock!" My words stop him in his tracks and his hand moves to cover the skin that sinks in. Hell his cheeks turn red, dusting at the knowledge that I, his worst enemy knows he is a lock.
"Ah… AHAHA! Oh Shizu-chan! You're a lock! Ahh!"
"Shut up! Fifty percent of the world population is a lock!" He snarls and now he goes after my shirt. I let him, I don't care who the hell knows honestly. He rips my shirt from my frame and stares for a minute. I can tell he's never seen a key before, the way he looks right now.

"How the hell is that supposed to match up to a lock?" He asks suddenly and I blink than I laugh, hard.
"You really have no idea, do you~?" I laugh harder.
"Sh-shut up flea of course I wouldn't know!"
"Mn, fine, I'll show you~!" Of course I don't expect my key to fit his lock, it never would. One hand each side… Shizuo's face is priceless right now. His cheeks turn red but this is considered an intimate act and I'm willing to bet he's never attempted before. The Key floats out easily, remaining right around my neck like a string is attached. I can feel it of course.

"Now then, if we were gonna do it, I'd take my key like so and pop it in like this~!" I laugh as the key enters the lock easily enough, drawing a hitched breath from him and then….

Click. Shizuo's face heats up more and his breathing suddenly deepens and I know why. It happened to me too and I can't understand it but… I think my key just unlocked Shizuo…


Seliphra: Well lookie there...
Izaya: Don't tell me you're putting smut into an early chapter!
Shizuo: Huh... hey I bottom again? I'M GETTING PREGNANT AGAIN?
Seliphra: I made Izaya pregnant twice, I'mma make you the same, get over it Shizuo...
Izaya: *chuckling in corner now*
Seliphra: So... if you hated this story you can leave now and never come back. If you liked it though I would be most honoured if you left a review! It only takes a few minutes and the nice reviews really help block the bad ones!
Izaya: And she'll have smut in chapter two apparently~!
Seliphra: I promise nothing...
