A/N: Okay, before I even start, let me explain myself. Normally, I cringe at the idea of a "vampire" fanfic. Like, when I started writing this, I felt like an idiot for the first 10 pages (this is only the preface, I have ALOT more). BUT I quickly got into it, and it's ended up getting my brain going quite alot.

My reason for choosing Citron as the vampire: So, before I even began writing, I had a long mental debate over who should be the vampire. On one hand, it fits Satoshi's personality ALOT more (he is the more traditionally masculine one with darker features). But it felt sort of corny. So then I looked at Citron, and it began to make sense. Without giving too much away, I was able to bring in a few aspects of the game and the anime (duh) and felt he fit it better. For one, his outfits/style are older (bloomers, his PJs, etc.), he's also less assuming (I mean come on, he's a complete cinnamon roll!).

Anyway, You guys will see in later chapters. I just wanted to do a halloween/october type of fanfic, and this is what came along :)

Song inspiration: "Flesh" by Simon Curtis

(btw, this chapter takes place in Citron's room of Prism Tower; not terribly important to this part, but just thought I'd let you guys know.)

PREFACE

"Do it." Satoshi grinned, his voice low and gravelly. He bared his neck, almost as if to dare him. Beneathe his flushed tanned skin, blood pulsed heavily with excitement. The light in his firey amber eyes shone back in the dark.

"S-Satoshi, I ca-"

"Sure, ya can." He gripped fistfuls of Citron's shirt, aggresively forcing him close. Nimble fingers began unbuttoning the front until it had been completely undone, dropping the fabric to the floor and exposing his cold pallid skin. "We've already gone this far, how's suckin' my blood any different?"

Hesitantly, the blond calculated and weighed his options. On one hand, Satoshi had a point. Why go out and 'feed' on an innocent person who would mean nothing to him, when there was a willing body here in his arms?

On the other hand, did he honestly want to subject his best friend to something so hideous and painful? Was he willing to give him his body just because it was more convienient than wondering around Miare City looking for a bite to eat?

"You're really into this, aren't you?.."

That much was evident. Indeed, Satoshi was more than willing. But that was only making it harder to stay in control of the primitive agressive urges that invaded Citron's head.

"Come on, Citron. Show me what you can do."

..

..

The temptation finally got to him.

"Okay." Both could feel the anticipation building as Citron's hands began removing Satoshi's shirt, tossing it aside. The cold tips of his fingers quivered, curling over his shoulders and digging his nails into his hot tanned skin.

Satoshi really did seem like quite the catch. Athletic, healthy and young. Of course, he was still growing (from what he could tell he'd hit puberty around 5 years ago), but for being a teenager, he was impressive.

Slowly he pressed his nose into the crook of his neck, feeling his pulse quicken. In his grip, he could feel the Satoshi's muscles tense.

Type B, huh?

This was going to be good. The vampire tipped his head, lips skimming over his victim's jugular.

"This will hurt, just to warn you. Normally, you wouldn't feel a thing.. b-because the trace. But since you're concious.." he kept his voice low, trying to fight off the primitive urge to just plunge into his flesh like some sort of animal.

True, victims should really be in kept in a trace, for their own sake. The potential danger rested in that, if he couldn't stand the pain or tried to escape.. it could send his body into shock, possibly being fatal.

"It's cool. I wouldn't want to forget this anyway." Satoshi lifted his head, giving his friend as much access as he needed.

Was it wrong that the hint of hesitation and even slight amount of fear that tinted his words aroused him?

"Once I get a little bit, I'll heal you.. I promise." He reassured. "Y-you might also want to calm down a bit, otherwise it might get kind of messy."

"Got it." Satoshi took a deep breathe, bracing himself for the inevitable pain that was sure to come.

Controll yourself..he's trusting you..

Citron reminded himself as he bared his teeth, fangs extending to their full extent. The razor sharp tips grazed over the Kanto boy's skin, as he felt the trainer's breathe hitch. Without waiting another second, he bit down, drawing blood with a sickening crack of broken skin.

"C-Citron.." Satoshi managed to squeek, his hands digging into the vampire's back. His breathing grew deeper and quicker, the stabbing pain growing as he felt himself bleed into Citron's mouth.

The blond let out a throaty moan. He tasted magnificent. For lack of a better comparision, that's all that could describe it. Certainly the Kanto boy took good care of himself, that much was obvious. The warm metallic liquid slid down his throat, reminding him of some sort of sweet scarlet candy.

The effect quickly started taking hold, sending his brain into a hungry, almost aggressive haze.

This is a strange feeling..it isn't usually this strong..

Lost in the mind-numbing sensation, his hand's shoved the other boy's shoulders into the wall, effectively trapping him. Satoshi's head hit with a dull thud. Citron could feel his fingers digging deep into his shoulders, clearly his body didn't want to let his newest prey go.

"Shit, you're str-stronger than you look." Satoshi panted, trying desperately remain standing. All the blood that had been in his head had either gone to feed the vampire, or down between his legs. His copper eyes drifted in and out of focus. "..thought you'd be kinda weak.. no offense.."

The other boy chuckled, stopping briefly to speak.

"You're pretty well off too." He ran one hand down the centre of Satoshi's stomach, feeling the muscles contract in a mix of pain and pleasure. "Getting excited, aren't you?" He lapped the small pool that had collected in Satoshi's collar bone, then sunk his fangs in again, puncturing his flesh and drinking in the crismon liquid greedily.

He could tell by the taste, that despite the initial pain, Satoshi seemed to enjoy this interaction. The chemicals his brain and body were producing told him all he needed to know. His blood burned as it slid down his throat, momentarily giving him an internal warmth that he hadn't felt in over a hundred years. Yes, Satoshi really was something special.

Returning his attention back to the moment, he took another couple heavy draws before pulling to admire the work he'd just done. Four deep gashes slowly trickled, leaving thin crimson trails running down the trainer's bare chest and slowly dappling the floor.

"It's beautiful.." he whispered under his breathe, a toothy grin spreading across his face. Normally he wouldn't be able to see the results of his feeding (due to the fact that he normally fed off of Prism Tower's many visitors publically). But Satoshi had given him this oppertunity, and in all honesty, it was going to be hard to go back.

Citron reached a hand out, scooping the blood dripping down Satoshi's torso into his hand and bringing it to his mouth. It'd be a shame to waste something so delicious..

Okay, I need to stop.. before this gets out of hand.

Gently, licked his fingers clean, then ran his tounge along the fresh wounds to seal them.

"Wow, that really does help.." Satoshi mumbled weakly, staring back at him with glazed half lidded eyes. The pain quickly subsided, a cold numbing sensation eased his damaged skin.

While the trainer seemed to have gotten more frail, Citron appeared stronger. It was like the life he had been drained of was now pumping through his friend's veins. His eyes, that were once a soft shade of blue, were now fiercely shining silver. Residue of Satoshi's blood still dripped down his chin.

"You might need to lay down." Citron eased his grip, feeling the trainer's body go slack in his arms. His head hung lazily and his complexion had lost it's normal healthy glow. Being careful to avoid any further harm, the vampire helped him back onto the bed.

"Thanks.." he heard the teen mumble quietly.

"You're not really supposed to be concious during a feeding, let alone getting turned on. You kind of gave me more than you need to.." Gently, eased the trainer down onto the sheets. Satoshi laid limply, watching the blond. "Although, it's also my fault. I got too excited and bit a little too deep."

"No problem.." his voice was barely more than a whisper.

"Would you like a shirt?" Citron offered, his eyes scanning over the dark haired teen's mostly exposed body. He seemed so frail compared to before.

"Nah, just get in bed.." Satoshi shifted to his side, holding the sheet open for Citron to join him.

Deciding that it'd be best to wait to clean up until morning, the blond obeyed.

"You do know I don't sleep, right?" He joked lightly. Satoshi didn't respond for a moment, keeping his gaze on Citron. Slowly he blinked, taking a weak breathe.

"Why are your eyes silver?" he managed to ask.

His question had caught him off gaurd, however, the blond quickly recovered.

"I'll tell you about it later." The boy smiled peacefully, leaning in to give him a soft kiss on the nose. "For now, just rest. I'll still be here when you wake up."

In the last moments of conciousness, Satoshi's mind began to wonder.

Despite knowing this boy for less than two weeks, he felt as though he could trust him (quite literally) with his life. Instead of ripping him to shreads, like vampires supposedly do, he treated him like gold. Why?..

It was because even though some would have called him a monster, Citron had more humanity than the majority of 'normal' people he met on a regular basis.

The last thing the trainer saw, was the gentle smile of his best friend, before slipping into sleep.

This is my first shot at a vamp-fic. So, I'm still trying to figure it out. Also, for those of you who follow me on Tumblr, this is the fic I was talking about when I said that I had 20 pages written but no clear starting point. Anyway, thanks for reading! I plan on focusing on this fic (and hopefully) updating atleast once a week for all of October.

Please review and spread the Diode love!
