A/N: Just a rather fluffy KuroFai oneshot that's been buzzing about my head lately. I kept wondering when in the hell Fai was going to feed. It almost seemed like he was starving himself through the Nihon arc. And so this fic was born. Read, review, enjoy.

Gathering angry fistfuls of his silken sheets, Fai moaned in desperate need, his hunger almost too much to bear. It had been far too long since he’d last fed--he couldn’t take it any longer. Kurogane’s blood was calling out to him, taunting him with the scent that made his mouth water in intense longing; with fleeting memories of that insufferable taste. The sensation of that warm, crimson liquid filling his mouth lingered on his tongue; he could almost feel Kurogane’s somewhat rough skin against his lips.

He had to feed tonight--now.

Slipping out from beneath his blankets, Fai sat up, daring to reconsider. It was the middle of the night. Everyone was surely asleep, Kurogane among them. He couldn’t be so selfish as to risk disturbing him for his own needs, could he? He felt like nothing but an inconvenience, but it sent a sharp pang of longing through his bones to even consider enduring the night without feeding, well aware that attempting such a thing would be something very close to torturous. He longed too greatly for the ecstasy that was the ninja’s blood; he longed for that taste that was sweet as honey on his lips. It was addicting. He needed it--he needed his fix. His body was practically screaming for it.

Fai stood then, remaining in his night robes as he slipped quietly out of his own room and was halfway down the hall before he had time to realize it. He stood awkwardly in front of Kurogane’s door for a moment, pulling in a deep breath, and with it, the scent of his blood, stronger than ever. His heart slammed madly in his chest as he pushed aside the door of rice paper and stepped inside, his lips curving up in an apologetic smile when he noticed that despite the reigning silence, Kurogane was, indeed, awake.

The ninja had always been a light sleeper. For a moment they remained silent, gold meeting crimson for the briefest of moments before Fai had to look away, his need raging through his veins far too strongly. Eventually, Kurogane spoke, taking Fai by surprise.

“You’re hungry,” he accused, narrowed his eyes slightly, “I don’t know why you waited so long.”

Fai’s heart didn’t quit throbbing. He cursed it internally, though he supposed it couldn’t be helped. It took everything he had not to pounce Kurogane at that very moment and drink him dry. “You were hurting. Almost dead and it was because of me. I couldn’t possibly ask you for blood at a time like that.”

Even now that Kurogane had healed, he was nothing but a burden to the ninja. In this case, however, his need of blood was overpowering his need for convenience. It was something like torture to be in such close proximity with the blood pumping through Kurogane’s veins. It had been like this for days, but he’d been able to put on the mask like always and bare it. Not anymore. That mask had crumbled along with his resistance. His body was screaming for it’s source of life. The logical half of his mind was still fighting the instinctive half as he dropped to his knees beside Kurogane’s futon and lightly touched his hand, eye pleading.

Kurogane sighed in annoyance with his actions. “It’s my responsibility to keep you alive, dammit. When you’re hungry, you feed,” at those words the ninja bared his neck as best he could, unknowing of the desperate temptations it instilled within him, “I’m not cutting my arm. You’re just going to have to feed like you’re supposed to. God damned idiot. Just feed already.”

Fai needed no more an invitation. He leaned forward and rested his lips at Kurogane’s pulse point and his hands gently on his shoulders, evaluating the steady drum of his heartbeat only for a moment before fastidiously sinking his teeth into his warm flesh and beginning to pull Kurogane’s warm, succulent blood from his body.

It was wrong to enjoy it. Fai knew he’d be damned to hell for enjoying it. But even so, he couldn’t have pulled himself away, even if he wanted to. Kurogane’s blood was like a fine wine and he swallowed savorously, feeling the satiation of his hunger in the very pit of his stomach.

Fai had become so lost in it that when he snapped back to his senses, he was terrified he’d taken far too much blood without realizing it. He pulled away quickly, licking away the remnants around the wound with one clean swipe of his tongue. Kurogane seemed to be alright. The ninja lowered his head and peered at Fai through narrowed crimson eyes, as if to evaluate him. Fai’s heart continued to thunder but now for a different reason.

“Y-you’re alright?” the blonde asked gently, tracing his fingers lightly over the still raw wound on his companion’s neck and feeling guilty.

“Fine,” he said roughly, “Don’t worry about it.”

Fai swallowed deeply, washing the remnants of blood from his tongue as he narrowed his own eye. “If I hurt you I want to know.”

“You didn’t,” Kurogane assured the blonde, sighing in frustration. “You need to stop worrying about my well being and start worrying about your own. I thought that we were past this.”

Fai looked away, setting his focus on his own pale hands, gathering fistfuls of his night robe. “We are. But I can’t help but worry that I’m hurting you when I feed. I have so little control over myself when I’m my vampiric senses take over--I couldn’t possibly stop myself if it was called for. I get so lost; I don’t realize how much blood I’ve taken from you until my hunger is satiated. I hate it.”

Kurogane tipped Fai’s face up and looked him in the eye, his tone entirely serious, “If you would feed when you need to instead of starving yourself half to death, you wouldn’t have to worry about things like that.”

“Kuro-sama, I hate feeling like a burden and that feeling is at its worst when I ask you to feed,” Fai admitted, “You shouldn’t have to sacrifice your blood for me.”

Or an arm either, Fai added mentally but refrained from actually saying it as he knew the ninja would yell at him.

“Dammit, Fai,” the magician reeled back at the use of his actual name, shocked. “I don’t give a shit if you have to live off of me. That was my choice. I chose to save you and I’ll gladly pay the price for that choice. I wasn’t going to let you die then and I’m certainly not going to let you die now because you chose to starve yourself. You may be an annoying little bastard, but damn it all if you’re not my annoying little bastard.” Fai couldn’t help curvature of his lips. Kurogane was blushing furiously, but he didn’t poke fun at him. Not this time. “So next time suck it up and ask. I’m not going to turn you away.”

Affection bubbled up inside of him and Fai did the only thing he thought logical. He threw his arms around Kurogane’s neck and hugged him tightly.

Maybe next time he wouldn’t wait quite so long to come to him.
