Well, this is both a consolation prize and an early BIRTHDAY present for my dear Spix! I'm REALLY proud of this little beauty, because I spent blood, sweat, and tears on it... Well, okay, maybe only sweat and tears... But either way, I wrote my heart and soul (and hand) out for this!

ANY WHO, please enjoy!

Indelible Night

Behind him, the recurring beat of the music over the speakers pounded against the door as he shut it. Tsuna took large gulps of the outside air, glad that the suffocating atmosphere from inside was dissipating. He leaned back against the wall beside the door, listening to the pulsing beat within the building that reverberated around him.

Yamamoto had brought him out tonight. His friend had wanted to take him to the 'most amazing club ever', as recommended by Ryouhei. Tsuna allowed the other to bring him; he'd never been big on dancing, but at least he knew how to without making much of a fool of himself, and he hadn't wanted to deny his best friend anything.

And so, he found himself crowded within the club, pressed tightly to Yamamoto as the crowd moved around them. He'd been endlessly jostled, hardly able to properly dance. Yamamoto had laughed, keeping him close so he wouldn't be lost in the crowd. Tsuna had lasted almost an entire hour before he'd slipped out for air.

The bitter smell of tobacco infiltrated his nose, and he turned his gaze to the left, following the curling smoke filtering through the air. The trail ended at a cigarette held lightly between pale fingers, pressed to equally pale lips before it was lowered and a cloud of gray smoke erupted as they parted.

Tsuna lifted his gaze and froze as it was caught by a pair of glimmering, jade eyes that flashed with a pleased light. The man was, for lack of a better word, beautiful. No, he wasn't just 'beautiful'; his beauty could not be categorized. It was a mesmerizingly tantalizing beauty that captivated and entranced, almost inhumanly so. And Tsuna had fallen into the trap, with the vague feeling that this man exuded a familiar air.

The man's lips tilted upwards as he pushed off from the wall he'd been leaning against. The cigarette fell and was crushed beneath his heel as he strode insouciantly towards the brunette. "A little late for being out, kid."

Tsuna could hardly suppress a shudder at the other's voice. There was a richly seductive undertone that was difficult to miss, bewitching with its power.

He'd swallowed, loud and nervously, before he responded with, "I'm not a kid." His teeth clicked together as he flushed, unable to move his eyes away to the floor in embarrassment.

A chuckle met his ears; a sound that made his heart rate increase substantially. "Excuse me, then. What brings you here?" He was closer now than he had been. There was a heady aroma filling Tsuna's nostrils, intoxicatingly seductive.

"Um, f-fresh air…crowded inside." Tsuna replied, feeling his self leaning, ever so slightly, towards the stranger. The other's smile widened at the act, eyes glimmering.

"I see…" He paused, watching Tsuna's eyes flutter. "What's your name?"

Warning flags had long ago arisen within Tsuna's mind, unheeded through the veil that had draped itself over Tsuna's brain. Tsuna gave a shy smile. "Sawada Tsunayoshi… Tsuna for short."

The other smiled in return, an act that just about made Tsuna swoon. "Gokudera Hayato, at your service." He reached forward and took Tsuna's hand, bringing it to his lips.

Tsuna swore his skin would ignite at any minute. His heart was beating almost erratically, drumming loudly in his ears and drowning all other sounds out. The name had sounded strangely familiar and had Tsuna been of sound mind then, he'd have inquired further. But –

Gokudera's lips met the back of his hand, and a flash of pain filtered through Tsuna's mind before everything went dark, and he was plunged into oblivion.

-.-.-.-.-

When Tsuna awoke, it was to a buzzing near his ear. He reached out a clammy hand and pressed for the alarm to snooze. There was a distinct, lingering smell of tobacco about him, familiar and heady in its presence.

Tsuna's eyes fluttered, heavy with sleep, and he groaned as the sun pained his eyes. His pillow came over his head as he turned, a wayward arm thrown over it to keep it in place. He didn't have to work today; there was no reason to be up so early.

As soon as he decided this, the front door opened with the familiar, "Tsuna~", call. He could hear Yamamoto's footsteps as he came down the hall to his room, and he gripped the pillow over his head.

"Tsuna?" Yamamoto had opened the door now, curiously looking into the small room. Tsuna listened as Yamamoto came nearer, a weird shift in his step audible in his ears. There was a dull thrumming coming with him, too, and Tsuna felt himself stirring towards the sound.

"Wakey-wakey, Tsuna. I brought you breakfast." Yamamoto gently lay a hand on the arm exposed over the pillow. Tsuna gasped as the originally dull thrum erupted into a deliciously exotic beat that overpowered his senses and demanded he give in.

Tsuna's hand moved and held Yamamoto's wrist, feeling the pulsing beat against his fingertips. "Yamamoto…" He called softly, feeling the other twitch at the way his name was called.

"Tsuna?" A worried hand fell over the other Tsuna grasped. The pulse doubled in power, and before Tsuna knew what had happened, he was atop Yamamoto, pinning him to the ground with his face buried in the other's neck.

Dear God, the smell, the smell! Tsuna couldn't ever remember Yamamoto smelling so, so...delectable.

But something…something was shooting off warning flags in his head. Something was wrong here. But, for the life of him, Tsuna couldn't concentrate enough to figure it out. He was nibbling at Yamamoto's neck; the other halfheartedly pushing at his torso in futile attempts to throw him off.

"Tsuna," Yamamoto breathed, arching as Tsuna's lips became a bit more insistent and harder. "What's gotten into you?"

Tsuna lifted his head, and Yamamoto turned his to face the shorter man. Yamamoto gave a gasp as he caught Tsuna's gaze, a blazing amber where it had been a gentle caramel before.

"Yamamoto…" The name came out a sensual slur, instantly stilling the darker brunette. Tsuna's lips lifted into a sultry smile that made Yamamoto fight from squirming beneath him.

"Yamamoto," he purred again, lowering his face back to the rufescent marks he'd left upon Yamamoto's neck. The dark brunette went almost limp beneath him, falling compliant to his wishes.

Yamamoto's head turned to the side, obediently exposing his neck to Tsuna. He gave a purr of approval as he neared the pulsing vein.

In the same instant, he heard his window slide up and Tsuna felt an intrusive presence enter. He snarled, turning blazing eyes to the intruder as he moved to cover Yamamoto.

The intruder was strikingly familiar, with silver hair, jade eyes, a slim build, and creamily pale skin. He surveyed the two upon the floor, steadily ignoring the snarling from the youth atop the other.

"Huh," he began, taking several steps towards them. Tsuna tensed as he did so. "I hadn't thought you'd begin so fast to change, Tsuna."

Tsuna growled, low and vehemently, as the intruder (why did he look so familiar?) was within arm's reach. Yamamoto had hardly taken notice of the other, waiting patiently for Tsuna to return his attention with a dreamy stare.

There was a still silence as the two stared each other down, before Tsuna launched himself at the intruder.

His lunge was caught as the other ducked and grabbed him by the waist before successfully pinning him to the ground by the wall. He sat upon Tsuna's lower back, holding the other's wrists behind his back to prevent any escape. "Now, now, Tsuna, don't make me accidentally hurt you. I know you wouldn't want to kill your dear friend."

The words slowly processed within Tsuna's mind as, now that he was no longer near a living pulse, he came back to himself. He stilled beneath the other, realizing at last who it was. "Gokudera-san? What do you mean?"

"Well, you can't very well have a human friend in your present state, Tsuna. You've barely begun changing and will most assuredly kill him." Replied Gokudera, shifting to more comfortably sit upon Tsuna's back.

The words struck Tsuna like a ton of bricks. Changing… Something was happening to him… And Gokudera had said 'human'… Did that mean that he…?

"You're not…" The words caught in his throat, froze on his tongue. He couldn't bring himself to say it. The implications were so –

"Human? Of course not, Tsuna."

Severe.

Tsuna had expected to feel his heartbeat instantly increase. Only…it didn't. He was… He was feeling light-headed, drowsy, and he could feel Gokudera lean over him to press lips to his neck.

"You're shutting down now, Tsuna." He explained in a whisper. "It's normal…procedure, if you will."

His wrists were released, and they fell limply to his sides. Strength was draining away, and Tsuna had to fight to keep his eyes open as Gokudera lifted him and moved him to the bed.

Yamamoto was sitting up now, dazedly confused as he watched the two, eyes still dreamily obscure. Briefly, Tsuna wondered if he would forget this, forget him…

But then a gentle nip at his neck drew his lethargic attention back to Gokudera. There was a searing pain as his teeth punctured his skin, and Tsuna swore his shoulder, and the veins within, began to burn incessantly. The feeling spread over his body, burning and searing fervently at anything inside him, and he could hear yelling as everything dimmed around him before he fell, once more, into oblivion.

-.-.-.-.-

When Tsuna awoke again, he was assaulted by the smell of cinnamon and tobacco. The mixture was strange, and Tsuna felt himself frown as he wrinkled his nose at the peculiar aroma.

A soft chuckle came from above him, and Tsuna opened his eyes.

The blinds and curtains at his windows had been partially closed, but Tsuna saw with perfect clarity – more than he usually could. Gokudera – his handsome face seemed so much more clear and beautiful – was smiling softly at him, jade eyes glimmering as he waited for Tsuna to speak.

Tsuna tore his gaze from the other, glancing about his room. It was empty but for the two of them. Yamamoto had left, or had been led away (more than likely by Gokudera).

"What happened?"

Gokudera's smile widened a bit, and Tsuna's breath hitched as he caught sight of the ends of suspiciously pointy canines (had those always been there?). "You've finished the Change, Tsuna." He replied simply.

Tsuna frowned, attempting to sit up. Gokudera helped him sit up, and Tsuna felt dizzy at the tantalizing feel of their skin touching. He forced himself to focus as his saliva dried his throat. "What Change?"

This time, Gokudera's smile was wider, and Tsuna could clearly see the canines (fangs, his mind hissed) that were unmistakably pointed. To become a creature of the night, of course." He sat himself beside Tsuna, taking his hands. "I changed you so we could be together, Tsuna, forever and a night."

The cheesy line would have easily melted Tsuna's heart before, but he made no acknowledgement as he stared at the other, soaking in the words from before.

At the prolonged silence, Gokudera shifted and began speaking. "It's a good thing you didn't partake in that human's blood. If you had consumed some before the Change, you'd – "

"A creature of the night…"

" – die…" Gokudera paused after Tsuna interrupted him. He gazed warily at the other "Yes…"

Tsuna met his gaze steadily. "What…kind…?" He somehow knew even before Gokudera replied, "A vampire."

Instantly, Tsuna recalled the inexplicable allure Yamamoto (no, not Yamamoto; his blood, he realized with a jolt) had had. His mind quickly recalled what he'd interrupted when Gokudera had been speaking. "I'd have died?" He squeaked, and cursed himself when Gokudera smiled at him.

"Yes. Your body shuts itself down after it has been injected with enough of a vampire's venom. If you take in blood before the Change completely occurs, it will mess with your body's shut down. It provides it with strength, and it'll try to stop the Change. The effort ultimately kills you." The ease with which Gokudera said it stupefied Tsuna. His mind whirled with questions and the first that came out was –

"Then why did you Change me!?"

Gokudera had leaned back at the outburst, jade eyes wide with surprise. "Because I wanted to be with you forever, Tsuna." He reiterated sincerely.

Tsuna had to swallow a golf-ball sized lump in his throat. This didn't make much sense... "But, why?" He dared to ask. "You could have just as easily sucked me dry and killed me…" He didn't know why he didn't add 'you don't even know me!'

Gokudera smiled, leaning in towards the brunette. "But from the moment I met you, I wanted to be with you forever, Tsuna… And vampires don't usually kill when they drink unless they get carried away."

Tsuna flushed, having to look away demurely. He wasn't used to such cheesy, romantic lines. It made his insides flutter, as though filled with cotton that teasingly brushed his insides. He'd never felt this way…

He jumped as Gokudera's hand cupped his, surprisingly warm against his own (weren't vampires cold?). He could hear the other's heartbeat, not as strongly as he had Yamamoto's, and he was vaguely reminded that he had thought vampires had no heartbeat, or were undead, whichever sounded better.

"Tsuna, let me show you how I feel about you." Gokudera's voice had become husky and its seductive allure immediately had Tsuna beneath its spell. The vampire was…perfection personified.

He was lain onto his back, Gokudera settling between his legs with ease. He lifted his hands and pressed them to Gokudera's chest. "Gokudera-kun, wait – "

"Ten."

Tsuna paused curiously, frowning at the random number said. Gokudera smiled fondly at him. "Ten years I waited for you, Juudaime…"

The nickname stirred a memory, long forgotten within the recesses of Tsuna's mind. Tsuna's hands lifted to cup Gokudera's cheeks as he gazed up at the other. "Gokudera-kun…?" He breathed. No wonder the other's name and face – everything – had been unnervingly familiar. "But, the accident…"

Gokudera smiled, thumbing away Tsuna's tears gently. "I was saved in the hospital by the leader of the Vongola clan, Reborn. It took me forever to convince him that you were really worthy of becoming one of us." He paused and kissed Tsuna's nose. "I'm sorry for taking so long, Juudaime."

Tsuna pulled back to press butterfly kisses along Tsuna's jaws, soaking up the soft sighs the other gave. He lifted Tsuna's shirt and lowered himself to lavish the other's nipples with attention.

Tsuna wriggled, biting his lip to keep from giggling as Gokudera's tongue flicked against his right nipple. A light gasp escaped him as Gokudera's right hand brushed against his groin. "Gokudera-kun…"

Gokudera hummed soothingly in response, bringing his free hand up to tweak at the forgotten nipple as he unzipped Tsuna's jeans. The brunette's timorousness was tangible. Gokudera was doing his best to quell it while he lifted his head to press their lips together as his hand dove into the other's pants to curl around the warm organ awaiting it.

He couldn't help a smile as Tsuna jerked back at the contact, breaking their lip lock as he murmured Gokudera's name. He hungrily watched as the other writhed beneath him, cheeks flushed, lips parted and wet with saliva, shirt bunched beneath his arms to reveal rosy nipples – one still toyed with by Gokudera and the other a flushed pink; his eyelids fluttered and opened, and Gokudera's breath hitched at the emotions reflected within the amber orbs; desire, longing, and – he recognized with a jolt – love.

His eyes misted over and he eagerly took Tsuna's lips as his hand pumped vigorously. He swallowed the cries he received at the sudden pace, pleased that Tsuna was thrusting up towards him. He'd waited ten, long years for this…

"Gokudera-kun…I'm…"

Gokudera promptly removed his hand, eliciting a despaired whimper from the brunette. He undid his pants, feeling Tsuna push up his shirt. He shivered as the smaller hands roamed over his torso, skimming his skin with tantalizing touches that felt almost as though they were scorching his skin in the most pleasurable of ways.

He swore his eyes almost crossed when Tsuna brushed shyly against his nipples. A shudder was released as Tsuna's hands continued down his torso to skim and stop at his navel. His pants had slid themselves down; Gokudera flushed lightly as he recalled that he'd forgotten underwear in his haste to come over.

His mouth opened to explain, but a choked groan came out as Tsuna's trembling hands wrapped around him. He flickered his gaze towards him, catching the heated amber eyes that practically shone in the dim light. "Juu – " His words were cut off at a squeeze-stroke-rub combination.

"No; Tsuna." The brunette corrected almost coquettishly. He was smiling – a little curl of his lips to match the teasing glimmer in his eyes.

Gokudera panted above him, shuddering at the continued pumping of his cock. He flinched as Tsuna's thumb rubbed insistently at the slit of his crown, pleasure increasing tenfold. Dreams were nothing compared to this.

"Juu – Tsuna," he quickly amended with a choked hiss as Tsuna mercilessly pressed at his slit. "L-Lube…?"

He tried not to moan at the loss of heat around him as Tsuna released him to reach over to the night table. His fingers slid on the knob, messily spreading the precum they'd gathered from Gokudera's cock while he fumbled to open the top drawer.

Tsuna was breathing rapidly, closing his eyes as Gokudera pressed wet kisses to his neck. His fingers managed to open the drawer, and Gokudera reached in and drew out a small tube of lotion.

Before he could open it himself, Tsuna had taken the tube and squirted the minty lotion onto his fingers. Gokudera could only watch as Tsuna reached between them and wriggled a finger within his self.

Tsuna's eyes had slit at the discomfort, teeth gritted as he forced a second finger inside without waiting. Gokudera quickly moved himself down, kicking off his pants completely and took Tsuna in his mouth.

The brunette writhed at the added sensation, a cry escaping him as he felt Gokudera pushing a finger in with the two of his. "A-Ahn! G-Gokudera-kun…!" The overload of sensations was set to push him entirely over.

"Tsuna," Gokudera murmured, lips brushing over the crown upon Tsuna's cock, eliciting a pleasured shudder from the other. He moved back, pulling out his and Tsuna's fingers as he messily lathered lotion on one hand to his cock.

The urgency had all but increased; Tsuna spread his legs further as Gokudera scooted closer, both panting wildly at the anticipation.

Gokudera paused just before touching. "It's going to – "

"I know…"

It was all Gokudera needed to immediately thrust in.

Tsuna howled at the pain, arching up beneath a slightly panicked Gokudera. He had never come this far with anyone – he had no idea it would hurt this much!

And just as suddenly, the pain diminished to a miniscule ache. He gasped at the rush – Gokudera frantically kissing his face and murmuring it would be all right – and lifted a shaky hand to Gokudera's cheek.

With the pain absent, Tsuna just wanted – needed – one thing. His breath was short; his skin was aflame; he needed release.

Tsuna pulled Gokudera to his lips, rejuvenated, and moved his hips up. Gokudera needed no further prompting and the bed began to squeak beneath them.

The brunette could swear he was drowning in a sea of ecstasy. He could virtually taste the corporeal heartbeat he heard pumping into him, driving him (already so close) further to the edge. He hardly noticed Gokudera suckling at his neck – his stomach tightening in the coming climax – until a sharp pain erupted and stars burst into his vision.

He was brought down from his high by the bittersweet pain of Gokudera licking the mark. Wearily, he turned his gaze to Gokudera curiously and was greeted with a smile. Blood was smeared over Gokudera's bottom lip, and Tsuna could smell the familiar odor of his own blood (how exactly he knew this, he didn't want to know).

He lifted a hand to touch the tender spot as Gokudera explained, "I wanted to properly mark you as mine, Tsuna…" He sounded a strange cross between timid and sublime.

A smile spread Tsuna's lips. "I'll always be yours, Hayato." Compelled to return the favor, Tsuna bit at Gokudera's neck, tasting his blood upon his tongue. He licked the puncture and turned a mirthful smile to the smoker. "You taste like cinnamon."

Gokudera kissed him, intermingling their blood. "You taste like mint." He responded when he pulled away with a wide grin.

Tsuna smiled and shifted so Gokudera could lay beside him. Once he did, Tsuna lay his head upon the other's chest, listening to the low thumping of Gokudera's heart.

They lay for a few moments before Tsuna asked, "What's going to happen now?"

Gokudera shifted slightly, scooting Tsuna closer. "We'll convalesce and then I'll take you to Reborn. He wanted to meet you in person and welcome you." He smiled endearingly at the brunette. "You'll like him."

Tsuna nodded, settling himself down. He closed his eyes with a tender sigh as Gokudera's fingers sorted through his hair.

At least he wouldn't have to worry too much about what would happen. He had Gokudera.

Everything would be fine.

-.-.-.-.-

Lips quirked up in amusement as binoculars were lowered. "Insemination complete. Good work, Hayato." A hand lifted to stroke the green lizard upon his shoulder, head tilted to lower his hat over his face. "Now, we wait."

-.-.-.-.-TBC-.-.-.-.-

Feedback is greatly appreciated!

I must be reading way too many vampire stories lately. XD I noticed as I reread my 'explanations' and saw a whole mix of stuff that I'd read. Well, I like it, and that's all that matters.

And Happy Birthday, Spix!!
