It's advisable to read the Vampire Trilogy first, or in tandem of chapters, ending with the last chapter of this. The Vampire trilogy is under the name 'Love-Bites' and is a sister-fic to this, the Slayer Trilogy. Hope you enjoy!

Don't Bite Back

And the boy sucks in the sob he's only half released.

Breathes deep through the pain so suddenly invading his every pore.

It was stupid, idiotic even.

When bitten, instinct strives for you to bite back... very rarely is that in the literal sense.

But, Riku had bitten back.

Deep.

Deep enough to taste his own blood now pumping through the predator growling and spitting and hissing and pinned beneath his weak but determined body.

And the blood was toxic as it burnt through him, seeming to fill his veins and tear them apart from the inside out.

And the boy inhales through his nose, unable to disconnect his teeth from his hunter, unable to stop himself sucking long draughts of the same blood that seemed to be burning him alive.

The predictor above him was fighting, digging her elbows out and scratching wildly whatever she could reach.

"Stop!" she screamed, voice like nails on a chalkboard and filled with agony, "you'll kill me!"

But Riku couldn't stop, stuck on the addicting feeling that was making him sick to his stomach and agonizing him right on through.

"Get off ME!" she screeched, raging against him like a tiny hurricane, nails digdigdigging into his chest and legs kicking out against the pavement she had him pinned to when all this started.

Riku had no strength, impossible realization when he was holding her so very tightly, forcing her to remain within reach as he attempted to bleed her dry. His arms would not release her, no matter how much he demanded of them.

His mouth would not stop its steady gulps of acid blood, his teeth would not relent its tight latch on the oh-so-pale throat.

"RIK-!" the predators scream was cut short by a slice of blade, swinging with a sharp hiss through the air and neatly separating head from body, spraying blood and finally creating enough momentum for Riku to let go, letting the body fall into his lap and the head to tumble a little ways to the left.

And an Angel stood there, splattered with a crimson mess of splash-back gore. Panting beneath a smooth sheen of sweat.

Sora.

And the boy's shining baby-blue eyes widened as blood dribbled from Riku's finally slack mouth, glistened with tears as Riku choked on his swallow of blood, body twisting in another wicked bout of agony as it raced through him.

And Sora hesitated.

Hand tightening ever so on his blade, legs trembling as his heart led him forward to help - and his head drove him forward to destroy.

"Riku..." he whispered, desperate and pleading, "please tell me you didn't bite back."

But Riku couldn't, back arching back as pain ripped through him again and again with unrelenting anti-mercy.

"Not you Riku, not you," Sora begged and pleaded to every god out there, anything that could listen to his prayers and gave enough of a damn to help.

"What... she... why?" Riku managed to gasp.

Sora stumbled finally forward, hands losing grip on the blade, letting it fall behind him as he captured Riku in his arms, "vampire," he whispered, sounding heartbroken, "never you, never supposed to find you."

"It... hurts..." and Riku latched onto Sora helplessly, lost and to pathetically weak to inform Sora that vampires were make-believe.

"I stayed away, they weren't supposed to find you," Sora whispered, "she bit you, tried to feed... you bit back. Why? Riku, angel-baby, why bite back?"

Already Riku's drained body was slowing it's shudders, already his pale skin was glowing milky and all the more beautiful, already warm skin was cooling and neat features strengthening, brightening. Perfection was spreading through agony.

"Why does it hurt like this?" Riku breathed, hissed almost in his haste to get the words audible.

"Toxic, poisonous. It'll kill you..." Sora whimpered, "...then..."

"Can't leave yet," Riku whined, back arching against another onslaught of pain, "so much to tell you."

Sora flinched, and in a heartbeat a flash of light the blade disappeared from it's place, and reclaimed Sora's hand, the boy looked at it with fresh horror, turned that same gaze to the dazed one searching his face.

"Not you Riku, not you," he whispered, throwing the blade to one side, "I love you Riku, angel-baby, your not leaving me."

Riku tensed, body stiff and eyes glowing with understanding and... reciprocation? "Poison," he let slip through his tight lips.

"It'll kill you, almost has," Sora assured him, eyes closing, "then it'll bring you back."

Those eyes widened, real understanding dawning, "vampire?"

Sora inclined his head, "with a slayer for protection."

"I can't-"

"You don't have a choice," Sora told him, eyes opening to a glare, "if you die... all I live for, all I fight for... the only reason I stay away enough to keep you alive..."

"Slayer..." Riku whispered, eyes closing with tension as the pain tore through him once more, "how long?"

"Forever, Riku sweetheart, since I could crawl I was taught how," the brunet whispered, pulling the older boy into his warmth, "but I've loved you for longer."

"Loved you even longer," Riku chuckled rather darkly, holding his friend close.

Even now, the shine of baby blue made Riku's heart soar, for at least its few final beats.

Slowly, almost shyly, Sora shifted, half laying while he still cradled Riku's head from the ground, he twined his feet around Riku's and rested his own head on the tensed still mostly-human chest before him, apparently ignorant to the crimson stain across them both.

"I'll love you forever and ever Riku baby, until the world rots around us and the sun comes crashing on down," he murmured, voice slightly muffled by Riku's chest, he shifted once more away from the labored heartbeat and looked up, into the emerald green gaze on him, "and then I'll love you still."

Riku's heart roared as his back arched with pain and his arms clutched Sora to his chest, "Love... you... always..." he panted.

"And always from a vampire is a very long time," Sora chuckled without mirth, before pressing his lips against his best friends.

The kiss deepened almost instantly, merging into a passionate moment full of heat and relief and that slight taint of regret that it took until Riku was dying for it to happen.

Sora pressed his body close to the others, hands twining in silver locks, his breath hitched in his chest as simultaneously the canines surrounding his tongue grew, and the heartbeat against his chest stopped.

And Riku panted violently into the kiss, breaking free to breathe in air that now tasted strangely pointless.

"Riku, honey-angel-baby, lets go find you some food," Sora whispered, pressing a slight kiss on his almost-enemy friend.

And the Blade of Light glimmered a little, before it faded into the dark, where Sora could call on it another Vampire later. It knowing, from the hunger in Riku's eyes and the fact Sora wasn't already bleeding, Riku (angel baby vampire) was as true with his love as the slayer.

And Sora rose, stiffly, pulling his best friend - lover up, and reversing his role to find a pathetic little someone for his vampire to bite.
