I dunno, I just wanted to write a vamp AU. Vampire Mickey!

In which supernatural creatures exist, after all.

Why do I have a roommate? was the first thing that passed through Michael's mind when he saw the man that entered his dorm with all his luggage. He had specifically asked not to have a dorm mate.

Sighing, he went back to the series he was watching. Sneaking out would be way harder now. And he'd have to go again soon, it had been a month since he had finished his supplies and he was starting to feel the need again.

The first day went quite well, the two didn't talk but at every moment Michael could hear his roommate's heartbeat, the need building stronger in him.

Two days and Michael knew the name of his roommate: Lucifer. Peculiar name, though Michael was used to strange names so it didn't affect him that much.

A week and Michael could feel his fangs pointing out at any moment during the day, rendering him unable to talk if he didn't want others to see them. Every sound was too loud, the smells were overwhelming.

He decided that that night, he'd go. He didn't want to harm anyone. When Lucifer was asleep, or he thought Lucifer was asleep, he got out of his bed and went to the hospital.

He had a friend there that let him in and gave him supplies so he wouldn't succumb, it was actually pretty helpful. But now, with a roommate, he couldn't stash up, he would have to hind another way.

Arriving at the hospital, he was relieved to see Benny was there. They didn't get along at first, but now they were good friends. Michael took what he needed, explaining his situation to Benny. The other vampire understood and told him to come whenever he needed.

Michael sneaked back in his dorm, for once not noticing the smudge of blood on his coat. Laying down in bed, he quickly fell asleep again, not noticing Lucifer's gaze on him in the dark.

He woke up and Lucifer was already awake, in the process of making pancakes.

"Where did you go last night?"

Michael froze. How did Lucifer know? Somehow, under Lucifer's inquisitive stare, he couldn't lie.

"I went to the hospital."

"At that hour?"

Michael felt a presence in his mind and quickly closed off to it. It was something his father had thought him, it worked quite well to keep his privacy private in front of mind-reading beings.

He saw Lucifer make a confused face, breaking the one of concentration he had a few moments before.

"What are you?" Lucifer asked and Michael was trapped.

Michael lowered his head in shame. "Vampire," he whispered. He had always hated how he was. Also, the fact that it had been over a century and he still looked twenty-two didn't help.

Lucifer somewhat smiled, almost as if he was impressed. "Never heard of a vamp able to block out a search."

As weirded out as he was, Michael was actually polite and didn't push Lucifer to tell him what he really was as Lucifer did to him. He only nodded and walked away to get changed.

A few weeks later, things started to get wired for Michael. He still went regularly to the hospital, but somehow still had some symptoms of lack of blood. He didn't understand what was happening.

Sometimes Lucifer and him would be talking, Michael would smile and suddenly Lucifer's fast heartbeat was all that he could hear. Other times, he only ever glanced at Lucifer and he would be overwhelmed, feeling a sudden and powerful need for no apparent reason.

One time, things went really overboard. Michael was only laying in bed. Lucifer wasn't there and Michael started wondering why. His thoughts slowly drifted and not really knowing how, he ended up curled in a ball, every one of his senses unbearable, his hunger so extreme he felt like he would die if he didn't drink, and now.

He heard the front door close, followed with a loud heartbeat. Panicking, knowing he wouldn't be able to face anyone in his current state, he locked himself in the bathroom.

He heard the breathing and heart of the person before he heard their footsteps growing louder. At this time, it was probably Lucifer. The scent he smelled confirmed it, it was Lucifer. And now he was probably on the other side of the door.

Michael's breathing became ragged, the only thing he could hear being the blood pumping in Lucifer's veins. He hadn't realized that his fangs were out or that he had fallen down, slumped against the door.

"Go away," he weakly whispered as something else peered inside him, the need for not only blood but something else. Desire. It wasn't the first time he felt like that, but it was certainly the most intense episode he had.

"What's wrong Mickey?" Lucifer asked, the concern in his voice making Michael's heart skip a beat, his speeding heartbeat not helping either.

"Go away," Michael repeated, unable to say anything else. He was heavily sweating by then, having long lost control over his body.

"What's wrong?" Lucifer said again, the concern in his voice replaced by fear.

"Please," Michael begged. He wouldn't be able to resist for long, everything that was happening in him, he just wanted to step out of the door and- no, Lucifer was his friend, he couldn't do that to him. Even if he felt something didn't mean he could force that on his friend.

"Why?" Lucifer's question was gentle, low, and made Michael completely lose it.

Michael rested his head on the door, a soft whine leaving his lips. His top lip continuously reached on his two fangs, trying to make it bleed, to taste blood even if it was his own.

A low moan escaped Michael's lips when he heard Lucifer lean down on the other side of the door. That was the least helpful thing, it only made Michael want him more, it made him want to- Lucifer is my friend, I'm not doing that to him, Michael repeated to himself like a mantra, hoping it would work and calm him down. It didn't.

He heard a plop in front of him and saw a bag of blood had appeared. Rushing, Michael gulped it down and it helped his blood need, but also succeeded in making his other hunger more vivid.

His head rolled to the side, his lips parted slightly, his eyes closed. He couldn't do it anymore. All he could hear was Lucifer's heart, his breathing, marvelling at how he could be the one to bring it up and fast. All he could smell was Lucifer's scent, the twinge of fear in it.

Michael tried to talk but all that he could produce was another high-pitched whine, starting to shake his head as every thought that passed in his head.

"Stop," he whispered. And it stopped.

In a moment all that he could hear was his frantic breathing. There was no heartbeat from the other side of the door, no breathing either. It was as if Lucifer had just suddenly died.

"Is it better?" he heard through the door. How- It wasn't better. Is was less worst, but it wasn't better. "Do you want me to leave?"

Michael didn't trust his voice and for a good reason. All that escaped his lips was a strange sound, but Lucifer interpreted it as a yes and left, not knowing how much of a mess Michael was on the other side.

It took a great deal of time for Michael to calm down, only after did he realize what a mess he was. He was still flushed, shaking, his sweat was starting to dry on him, blood was dripping down his chin and he was both mentally and physically exhausted.

He decided to take a shower and sighed at his 'problem'. Things had gone really out of hand.

As he washed himself, he wondered what had provoked such an intense reaction. Yes, he liked Lucifer, more than a friend, but it wasn't a reason to react like that. He had liked some people before, but it never was so intense. In fact, the only time it hit him that hard was when he met an angel. What did mean?

Michael went to bed, trying to get some sleep, but he simply couldn't. Thankfully, Lucifer still wasn't there, though Michael couldn't help but wonder how he just stopped all his vital signs yet still lived. Maybe... Could Lucifer be an angel? That would explain it...

When he got up the next day, he smelled pancakes. Smiling, he went to the kitchen, thankful when he didn't have another episode. Now that it had started though, it was bound to happen more, until- no, he didn't want to think of it, Lucifer would never like him like that.

"What was that, yesterday? Or should I say tonight, it was actually 1:36 a.m." Lucifer asked.

Michael was shaking only at the thought. "You're an angel, right?"

Lucifer's surprised face confirmed it. "How-"

"You tried to sneak into my thoughts and you were able to stop your vital signs. You're an angel, am I wrong?"

"Yeah, I'm one, but-"

Michael understood what Lucifer couldn't speak. He lowered his head in shame. "Werewolves aren't the only ones with that Alpha/Beta/Omega system. The exact same thing happened about sixty years ago, when I fell in love with an angel. It went on and on until they confessed their love and-" Michael trailed off at the memory. It had ended up so badly. -"and we had sex. But then a week later they were killed."

"Sorry." Michael could almost see the gears spinning in Lucifer's head.

"It's nothing, I'm over it," Michael said. Then, muttering: "I was over it a day after."

They ate their pancakes, Lucifer washing the dishes. "You have any classes today?" he suddenly asked and Michael shook his head. He didn't see Lucifer's nervousness.

"Nah, it's my free day. Thought you'd know it by now."

Lucifer absentmindedly nodded. He walked back to the bedroom, gesturing for Michael to follow him saying he wanted to show him something. Frowning at the lack of information he was given, Michael followed a little late, freezing when he passed the door.

His breath caught in his throat as his eyes trailed on Lucifer's magnificent wings. He could feel himself heat up at the thought of how easy it would be to just step closer and bury his hand in these soft feathers, perfectly knowing what would happen. He saw how shy Lucifer looked. It was normal though, showing your wings was a pretty intimate gesture.

He started to shake, trying to ignore the scream of every one of the cells in his body urging him to take Lucifer right there. His senses sharpened up again, he could feel everything as Lucifer stepped forward and placed a hesitant kiss on his lips.

Michael kissed back passionately, enthralled as the kiss heated up at the way Lucifer's heart beat faster, at the soft heat of the skin under his hands. When his fangs scratched Lucifer's lips, the angel's small gasp echoed like a scream in his ears. He smiled into the kiss, pushing Lucifer against the wall by his wings, the moan that escaped Lucifer's lips making even more eager, if that was even possible.

Later, Michael and Lucifer were laying in bed, Lucifer smiling like an idiot and Michael not really believing what just happened. Not the fact that they had sex, but the fact that it was actually Lucifer who initiated it- technically- and that they just confessed their love for each other. He just hoped this time it would last longer.

Hey, so that was a thousand words more than the usual, I just thought there was no good way I could end this in a thousand words so here it is.

I know, it's not really a 'vampire' AU, but whatever, it's my book and I do what I want. I like the idea of having a vamp AU where the vampire trait didn't take all the place and I wanted to do an A/B/O OS, I know it doesn't do it much either but I don't care. I think it's good so haters, suck it up.
