Such a simple thing, a knock was all it would would take. And yet, Yuuki found herself frozen outside Zero's door.

Could he hear her heartbeat or could he possibly smell her through the door? The thought decided her, there was no point in lingering if he was already aware of her presence.

She didn't get an answer but she opened the door anyway, surprised to find it unlocked. "Zero?" She asked hesitantly as her eyes adjusted to the dark. He was sitting on his bed and didn't seem to be aware of her. "Zero?" She whispered again, as she reached him. Slowly she reached out and was met with the smack of his palm.

It stung but he hadn't used more force than necessary. He always seemed to be aware of how much to hurt her without really hurting her. Always driving her away from him anytime they seemed to get close.

…

"Go away!" Zero growled, as he tried to fight his instincts. He wanted to pounce on her. He wanted to bite her, caress her. He wanted to continue where they had left off in the infirmary. But most of all, the strongest was the need to feed.

He was so focused on his self control that he almost didn't notice her head to the door and turn the lock on his door.

….

The click of the lock echoed through the room, making Yuuki tremble. She had never been in a locked room with Zero before, had never even thought about locking a door until after he had started biting her. At first it had been a fleeting thought due to the worry of him being found out. But now she wanted to lock the door for other reasons.

She knew that by locking the door she had stated she wasn't leaving.

His eyes glowed through the darkness as he looked at her.

"Why do you keep pushing me away Zero?" she asked as she slowly walked toward him.

…..

Zero watched her approach him and wondered if she knew what he was thinking. Could she even guess such a thing?

….

Yuuki stopped just in front of Zero, not even an arm length away. She reached for him again.

….

Zero didn't even stop to think. He grabbed the arm that was reaching for him and used the momentum to pull her onto the bed. He twisted with it so that he lay above her.

…

Yuuki looked up into Zero's blood filled eyes and tried to calm her heart. It wasn't too unlike the time she had stopped him from shooting himself. But this time it felt different, having him above her meant more.

"Why do you keep pushing me away?" she repeated in a soft whisper. Hoping he would answer.

…..

Zero glared at Yuuki, "Because I don't want to hurt you." The words sounded like a growl. "Do you know what I want to do right now? Do you?" He paused as the tidal wave of emotions washed over him.

He stroked her soft hair and grabbed her chin. "I want to kiss you." He watched her face to see her reaction. "I want to touch you, caress you. Taste every single inch of your body. I want to make love to you, and in that moment when it feels like it can't get any better, I want to bite you and feed while you climax beneath me."

…

Yuuki's eyes widened, as she comprehended his words. Her body buzzed beneath his and she tried to fight the lump within her now dry throat.

"Why don't you?" the words came out as barely more than a whisper."

…

Shock raced through Zero's veins like iced fire. In all his fantasies they always ended with her hating him or possibly even…gone. Maybe she didn't understand what he had meant. She was innocent, and he was sure that he had taken her first kiss but how had such a pure mind been turned so wonton?

The soft floral scent that surrounded her washed over him as she leaned down. She hesitated just a moment and whispered, "Please stop pushing me away," before she closed the distance and initiated a kiss.

….

She was almost hesitant even though her lips were mashed against his. He really needed to teach her how to kiss properly.

He could feel her trembling beneath him, her hands gripping his shoulders as he gave into the kiss.

He pulled his head beack enough to release the pressure turning the kiss softer. He allowed his mouth to trail along her skin, starting at the corner of her mouth and making his way to her neck.

This time when the hunger filled him, he listened and sank his teeth into her neck, letting the blood flow into his mouth.

He only took a few swallows before pushing up with his hands so he could look into her eyes. There was no fear in them as she looked back.

Taking a deep breath he bent down for a kiss, coaxing her mouth open to his exploration.

…..

Yuuki paused at the taste of blood, her blood, on Zero's tongue. She knew she could accept this darker side of him or loose him entirely. Put that way there was no need to decide.

She let go the last of her reservations and returned the kiss.

….

Relief flooded through Zero, he had felt the hesitation and wondered how she would react. Her response was everything he had never allowed himself to hope it would be.

Taking in her acceptance he deepened the kiss, allowing his full hunger to release.

His body relaxed and sank into hers making his body ache for more.

…..

Yuuki moaned, as she felt Zero press more against her, letting her feel him, hard against her.

Everywhere he touched burned with an almost unbearable fire. And she hoped the torment would never end, even as she sought release from it.

….

Zero broke from her mouth and would have smiled at her cry if he wasn't wound so tight.

He wanted to take her now, but he knew that doing so would hurt her and he had fantasized for years about what he wanted to do to her.

He lowered his head to her neck and licked the blood that pooled on the surface as his hands unbuttoned her blouse.

…

Cool air fanned across Yuuki's chest before she felt Zero's hand slide under her bra to grasp one of her breasts.

Instinct fully, she bucked her hips against his and wasn't sure if the act helped or made it worse.

She let out a frustrated whimper at the feelings that plagued her body.

…..

Zero could feel her frustration and slide his other hand under her skirt. Pushing past her panties, he slid his finger inside her, relishing at the moisture and heat.

He now knew with certainty that there was no way she could accept him yet. He slowly moved his finger as he licked her breasts.

…..

Yuuki moaned and moved her hips in rhythm with his finger. It was amazing, each movement was too intense, and yet she wanted it like nothing else. She could feel his mouth on her breast, tongue dancing across her nipples.

She felt him slip a second finger inside, once again filling her. His mouth made a trail down her body as he made his way to his fingers.

Yuuki watched, mesmerized when he stopped and looked at her from between her legs. Was he going to bite her again? The thought excited her even though she knew it shouldn't. Then he smiled wickedly before removing his fingers and replacing them with his tongue.

Pleasure broke through her making her buck her hips into his face as she tilted her head back. She could feel his arms wrapping around her, gripping her hips and holding her up in that position as he pleasured her with his mouth.

…

Zero lost himself in the taste of Yuuki; it was mixed with her body wash. She must have taken a shower after the infirmary. Even with the taste of soap it was better than her blood.

Her moans filled his mind leaving behind satisfaction. It almost made him loose control but he fought to only hold her tight enough to keep her in place.

Rolling his eyes upward, he watched her, noticing the blush in her cheeks.

…..

Embarrassment flooded Yuuki as Zero looked at her. She could feel him exploring her, and she was grateful she had taken a shower.

She made a sound as he lifted up and dragged his body over hers.

…..

Zero pressed his lips to Yuuki's wanting to posses her. He wanted her, now. The hesitant flicks of her tongue on his made it hard to breath. He could feel his heart racing and knew that she wasn't ready but he couldn't wait.

Sliding one hand down, he opened his trousers.

….

Yuuki was lost within the kiss; she could taste herself upon him. Before she would have baulked at the thought, but strangely it was erotic.

Then she felt something press against her opening. Breaking the kiss she looked into Zero's eyes.

…

Zero held Yuuki's gaze as he slowly, carefully, slid within her. He could see the pain in her eyes but he couldn't stop.

Finally he was fully in. He paused, allowing her body to accept him.

"Are you ok?" He whispered, praying that she wouldn't ask him to stop.

…

Yuuki nodded, unable to speak. She had known it would hurt, but knowing and feeling were different.

She felt him pull back and, worried he would stop, she grabbed his shoulders saying, "Don't stop, please."

…..

Zero had heard the tremble in her voice and almost swore.

He slowly started moving within her, trying to be careful.

….

Slowly, the pleasure returned as Yuuki felt her body accept the change. Her grip on his shoulders tightened and her body began to move once again.

…..

Zero felt the change and knew that she was ready, so he quickened his pace. It was amazing, and with every stroke he watched her.

Her eyes were locked on his, and together they began to explore the limits.

Faster and faster, until his heart was pumping so hard he felt it would burst. Her moans driving him on as he fought against the urge to finish it. Not yet, he thought, she's almost there.

….

Yuuki clung to his shoulders. She felt decadent as she looked into his blood-red eyes. Her hips met his with force as she felt herself be taken.

…

Zero sank his teeth in Yuuki's neck as he felt her come beneath him and the world exploded around them. It was better than he had imagined and he felt himself take more of her blood than usual, drunk upon the taste.

He had to force himself to stop and he dropped his head on her shoulder. His breath was ragged and he felt drained but more alive than ever before. It had been wonderful and glorious.

He took a few minutes to calm down before lifting up to look at Yuuki.

…

Yuuki smiled up at him, basking in the glow. Now that the hunger was gone, his eyes were normal.

She felt relaxed and tired. She hoped he would lay with her, at least for a while.

…

Her smile had brushed away his worries and he found himself smiling back as he brushed back her hair with his hand.

She looked tired. She looked beautiful. And with that thought he rolled onto his side and pulled her against him so that her head lay on his shoulder. Resting his head against her, he sighed in contentment. They could clean up later, right now he just wanted to hold her.

A few minutes later, as he was about to drift off to sleep, he heard her whisper, "I love you."

His heart skipped a beat, and it took him a minute before he could reply. "I love you too."
