First chapter is in Kiryu's point of view. ^_^ Enjoy!


To live forever...humans can only assume as wishful thinking. For us vampires, it's a curse. When you become a vampire, your ties to the human world have been completely severed. Keeping those loved ones around will cause you pain because you have to watch them grow old, get sick, then die... Everyone you knew in your human life will eventually be dead to you. They'll die sooner or later so what's the point of keeping them around? Humans are fleeting creatures. Their pitiful lives passing through what is only a millisecond for vampires. They're despicable beings who's life mean absolutely nothing to us. Their blood, their life force is nourishment for us. It's the only thing that matters.

What happens when you find someone you care for? Someone who's a lowly human? How could you stand to be around them? Everything about that beloved is so tempting. Their frailty, the smell of their blood, the sound of their heart, their warmth, their short lifespans... All of those things that meant nothing suddenly seems so beautiful to you when you love that human.

It's the one thing that can make a vampire forget what he is for that fleeting second. We easily forget that we're actually monsters that devour blood.

But what happens when we call on our own bluff, when we can't convince ourselves that deep down, we really aren't the stuff of nightmares?

I was at Yusei's place. The thought of us being together had crossed my mind before. But because of what I am, I couldn't do it. I didn't want to hurt Yusei. I couldn't bear the thought of that or even worse. I shuddered at the thought. But after several heated moments between us, we decided to risk it. Somewhere in the back of my mind, I knew I didn't want to do this with him. I don't think when a vampire makes love to a human, it ends well. I never heard of it nor did I hear it ended well. Still in my mind, I didn't want to go through with it. I could hurt him. However, Yusei said he didn't care. The only thing he wanted was to be with me. How could I say no to that?

So that discussion and my conflicting thoughts lead us to this moment.

Yusei's tan fingers traced over the bluish veins on my the back of my hand, marveling at the smoothness of my pale skin as we lay in his bed together. He seemed unfazed by the coolness of it or at the least very used to it. My skin is as cold as death yet he doesn't care. It's strange yet remarkable. He's a strange human, Yusei, but I love him. He is more beautiful than any human I've seen in my 300 years of living. I never found anything I wanted to protect or value other than him.

Yusei is very beautiful. I love everything about him. His tan skin, his spiky onyx hair with gold streaks in them, his ocean blue eyes, his warmth, the way he smells...Everything.

My hand moved too quickly for him to see and I held his small hand in my own then laced my fingers through his. He was startled but he smiled as he looked at our laced hand then to me. I brought it up to my lips and kissed it. I could smell his blood pulsating through his veins. His sweet scent radiating off his tan skin. I'm risking his very safety by being with him like this. I've told him that when we've confessed our feelings to each other a year ago. I've told Yusei that there is a chance I won't be able to control myself. He knew that very well but he still wanted to go through this with me.

"I love you, Kiryu." he told me, his breathing was uneven. It was clear that he was nervous. Not because he's with a vampire, it's because it's his first time having sex period.

"I love you too, Yusei." His blue eyes looked away from mine as he turned a faint shade of red. "We don't have to do this if you don't want to."

He touched his forehead to mine. "I want you." he said as his ocean blue orbs bore into my ocher with determination and lust. "Always." I could drown in his beautiful eyes forever. He pulled me closer and pressed his lips to mine and his very essence started to overwhelm my five senses. He's so warm. So beautiful. He scent smells delicious. His mouth tasted wonderful. His voice filled my ears every time I touched his bare skin.

I wanted him more than anything right now. But I had to be careful. Yusei is a human after all. So fragile...I could hurt him or even worse kill him by accident. Even though he was nervous, Yusei was the one calming me.

"It's okay." he murmured, it sounded like he was whispering. "I trust you."

I kissed him as I slowly pressed a tentative finger covered with lubricant against his entrance, applying as little pressure I can. He mewled when it was already inside of him. Then I moved it and pushed another finger in there carefully, Yusei groaned slightly as I flinched at his sound. That sounded like he was in pain. I had a right mind to stop but he shook his head as if he read my mind. I pushed my third and final finger in him and Yusei arched his back as a breathless moan escaped his throat. He twitched then writhed every time I moved them in him, stretching him out gradually. I pulled my fingers out of him before he got used to them.

"Yusei..." I breathed before I kissed him, flooding his senses in an attempt to dilute the pain that will happen elsewhere. It worked to an certain extent, Yusei arched his back, his muscles tightened around me and a painful groan escaped his tan lips. He may be a human but this was getting uncomfortable. I hid my discomfort and kissed his neck, his cheek, his lips hoping he'll relax some.

"Yusei, relax." I said, touching his face that was now covered in a sheen of sweat. Just my touching did it for him. Yusei relaxed some, allowing for me to push deeper into him. His arms wrapped around my neck immediately after I started to move. Carefully.

Yusei and I moaned simultaneously before I had started setting a rhythm. We were in ecstasy as our bodies molded into one. Hot and cold, tan against pale. It was perfect. I did everything I could to keep myself in control even when Yusei had started thrusting his small hips violently upwards in attempt to increase the friction and speed. I groaned in delight at the feeling, wanting more of it then responded by matching him thrust for thrust. I unintentionally buried my face into his neck as I moaned. His heart, the sound of his blood and the smell of it was overwhelming me. It was more potent to me now.

I stopped moving and pulled myself away from his neck. But the smell was still there, his body was too tempting. I'm not sure if I can control myself now. I want his blood, I want him. The smell of it is overpowering, drawing me in. His heart is loud. I can hear his blood, I can smell it.

Then I heard his voice in between pants, "Go ahead. I want you to." I looked down at him and he was looking back up at me. He touched my face, making me shudder from the contact. "Kiryu, drink." I was about to protest but he shook his head. "You're thirsty. I can see it in your eyes. Do it, please..."

I leaned my head back down as Yusei exposed more of his neck to me. I licked it then sunk my fangs into his neck. Yusei cried out in pain and ecstasy as his blood rushed into my mouth. It tasted even better than I thought. So sweet... Just a little more. I stopped drinking to kiss him as I started to move in him again. The combined taste of his blood and his mouth was just so exquisite, it was almost intoxicating. It won't be any longer. Yusei was so close now. The sight of him now is so beautiful. His entire body is flushed and covered in sweat and a little blood. I couldn't control myself anymore at this point. My mouth went to his neck again to drink some more of his delicious blood, drinking huge mouthfuls while I thrusted into him.

With my name being cried to the heavens as Yusei violently orgasmed and his seed coated both of our stomachs. Then with a low groan, I came into him and he shuddered lightly from my orgasm. I pulled out of him then held his small body close to mine, still drinking from his neck feverishly. His lithe arms then became limp around my neck. I didn't think nothing of it until I heard his heart slowing moments later. It didn't sound right and I panicked.

Oh god, please don't let him be dead... He can't. I can't believe I couldn't control myself!

"Yusei?" I said, touching his face then checked for a pulse by touching his neck. His heart rate faltered then stopped. The heat of his body was dissipating quickly. No...no...NO!

I...killed him. My chest heaved several times and then I screamed, gripping large clumps of my hair as I sobbed. I'm a despicable being for killing someone so beautiful. I don't care what I am but to kill someone you love...that's the biggest taboo I had committed. I hated it. I hated myself for doing it. Losing control like that. I wish I wasn't a vampire because then...I wouldn't have killed the one I loved...

"You can't go attacking humans like that, Kiryu. Do you want to expose us for what we really are?" Roman hissed at me hours after the Neo Domino police found his bloody, mangled body. We were standing in the halls of our hideout or lair if you will. The dim lighting made our skin seem less chalky pale than it already is. Several other vampires stared at us as they passed by. I ignored them.

"It was nothing like that." I answered him, sounding lifeless.

"But you couldn't control yourself around that human pet of yours." My eyes widened in shock and anger. He wasn't a fucking pet! "Ah, I'm right. It seems my suspicions for the last year were confirmed. A human, Kiryu? Really? And he's very well known too. Yusei Fudo. Has a mother who's a doctor and his father is a scientist."

"How do you know about him?" I asked.

"I made you, Kiryu. I know every move you do, every thought that crosses your mind. You really thought I wouldn't know? That you fell in love with some insignificant human? I could smell his stink all over you when you came home. That boy is a human, Kiryu. He's nothing. It was meaningless to keep him around."

I was too furious to even speak. Yusei is dead and all Roman could do is criticize and insult him... He's fucking dead and can't defend himself and he's talking about Yusei like he's a speck of dirt. Before I would do something else I'd regret, oh wait, I wouldn't regret killing Roman for this. For insulting Yusei. I had to walk before I actually try to kill him.

"We're not done talking, Kiryu." He called after me.

"I say we are!"

"No, you listen to me." Roman darted over to me then whirled me around to face him.

"No, fuck you." I spat at him, prying his hands off of me before walking away. I was still so furious from the conversation with Roman. This was the first emotion I showed since Yusei had died. I tried not to let myself feel any emotion but when it came to Yusei, I always lose it. I loved the one I've killed too much. He had my heart. When he died, he took it with him. The tears started forming in my eyes to the point when they had brimmed over and I had wiped them away. I regret ever killing Yusei. It's my biggest regret I have in my long, sorry life. I could never change it. I can't die though I wish I could. The sweet death could erase that memory from my mind.

I left the lair in search of something to eat. At this point, I couldn't care less whether or not I take a life. He's not here with me anymore so what's the point on feeding on donated blood? When I met Yusei, I stopped drinking live blood. It was a huge transition but worth it if I could keep him safe. It's still so painful thinking of him, his face, his smile... It hurts. No amount of blood could numb the pain I feel. The cool night air brushed against my face as I opened the doors and walked outside. Since I didn't want to go back, I might as well as dine all night.

I've already drained four humans without any remorse. I was so full already when I started on my sixth. One of my vampire comrades, Carly, had to pull me off of the human woman I was feeding on. She was found later on, barely alive. My stomach turned as I collapsed onto the ground and I ended up vomiting up some of the blood. When I could finally breathe, Carly pulled me back up to my feet and dragged me into an alley since my body wouldn't listen to my brain anymore.

"So what are you trying to accomplish by gorging on humans?" she asked. I didn't answer her as I leaned up against the building. "I know you loved him but there's nothing you can do about it."

I sighed. Then everything I ever thought came out in a rush as I sunk down to the ground and buried my face in my hands. "I can't believe I lost control. And because of what I am, I've killed someone I cared about. I didn't care about anything else before him. When I saw him for the first time, I knew I wanted him for myself. Not as food, but someone I could love. He may be a human but I loved that human. Everything about him draws me in. I cherished him more than anything in the world."

"You really loved him." she said, it didn't sound like a question. I let out a teary exhale. Talking about him out loud hurt more than just thinking about him.

"I can't talk about this anymore." I finally said, looking up at Carly. Her onyx eyes looked concerned.

"Of course." she replied, understanding my mood quickly. "Let's go home."

"I'm not going back there. Not now." I immediately told Carly. She nodded then flitted away without another word. I sighed heavily, wishing I could die. I rested my head on my knees and I have no idea how I fell asleep there later on.

I soon woke up to the sun shining into the alley and the many humans walking and cars driving by. It was high noon and it stung my eyes rather painfully. I searched my pockets for, my object now, sunglasses then slid them onto my face as I stood up carefully. The sun still bothered my eyes as I turned out of the alley. There was nothing I wanted to do with my day. There was no point in anything anymore so I have no idea how or when I ended up in the park. The light, warm breeze swayed the tree branches and blew tendrals of my hair into my face. I sat down on the park benches and stared at the toddlers play while their mothers watched them. The smell of the humans' blood reached my nose. Some smelled good. Others smelled okay. There were a few that smelled horrible. The bad smell made my nose wrinkle a bit. Everyone's hearts were so loud. I wasn't hungry now but I couldn't deny the fact that I was hearing the appealness of it.

I wished to drown it all out...

"Kiryu!" I turned and it was Carly darting towards me quickly but slow enough for the humans to see. She didn't want to scare the humans with her ability to run at an blinding speed.

"What is it?" I asked, examining her face. It was a mix of emotions. Happy, shocked, scared and doubt. "Carly, what?"

"You should come back to the lair right away." I blinked at her, confused. She's not serious.

"Wait, why? What is there for me back there?" She grabbed my arm and pulled me to my feet without effort.

"There is something you should see." Carly answered me. I could see the horror in her eyes and it made my stomach churn uncomfortably. Something wasn't right about this. The way Carly is acting didn't make me feel any better. I was feeling more anxious as she pulled me towards her car. We jumped in then she started driving. My stomach was starting to fill with butterflies and I had no idea why. Just what the hell is going on?


A/N: I have no idea how or why I decided to write this. I guess if I had a reason, it would be because I wanted to make an vampire AU fanfiction for Kiryu and Yusei since there aren't any yet. :( Oh wait, that is the reason...^^; I'm not sure if there is a plot for this story since my intent for this was for it to be a oneshot. ^^; I'm not sure how many chapters there will be either. Oh right, I wrote this today and it just stemmed from there. I'm so weird. :D And I love vampires. :3 Not the sparklely ones... pfft Twilight. Really? Vampires don't sparkle... *shakes her head in disbelief* I'm probably gonna get some flames from the Twilighters just for that comment. ^^;

Oh well. I hope everyone has enjoyed my first chapter of this story. :3 There will be more so add this to your alerts, only if you want to. :D

Reviews are much appreciated! ^_^ I love you all. :3
