A/N: This fic is a collaborative work written for the lovely riverance and based on her beautiful Twilight Klaine artwork. The link to her page is on my profile. Do go check out her work! It's all kinds of wonderful! :D

That being said, this is essentially a Twilight Klaine AU but with a few twists of my own. If you choose to read, I hope you enjoy the story!

The mattress groaned under the weight of the two adolescent bodies now tangled up in each other. A heavy, but warm spring rain beat rhythmically and steadily against the siding and windows of the house, and through the blur of gray rain clouding up the narrow basement window, a minute beam of moonlight fought its way through and cast itself across the otherwise dark room.

Kurt pressed his lips gently against the warm, rough flesh of the neck of the boy beneath him. His lips parted as he scraped his teeth across his pulse point before he pierced the skin, clamping his jaw around it as a moan escaped its owner. Kurt sucked hard and drank openly, savoring the taste he had become so accustomed to, so - addicted to. When he moved his mouth away, Kurt examined the small puncture wounds, reaching his hand up to gently trace his fingertips across the bloody, broken flesh.

"I love how you taste. I will never get bored of it - or you," Kurt softly growled, licking the remaining drops of blood from his lips and teeth.

"I'm all yours, Kurt. All of me. I told you, I'll always be here for you...for as long as I can," Blaine said, reaching his hand up to cup Kurt's smooth-as-marble, alabaster cheek. Then he pulled away. Kurt's face grew stony for a moment before his expression softened, and he lowered his head by Blaine's ear.

Then Kurt placed his cold lips and tongue, warmed only by the transfer of Blaine's hot, sanguine liquid life force, against his throat and lapped gently at the thin trails of blood still escaping. A shiver ran the length of Blaine's body, and then, as Kurt watched, the wound almost suddenly began to close up, leaving behind only two faint, circular scars.

"It's remarkable, really," Kurt mused. "That we can be this close - that, 'us' is actually working."

"I never thought I would survive, and I wasn't sure I would survive you," Blaine said.

The rain continued to fall. A tense silence passed between them, and the soft puffs of their breath sounded deafening in the silent, empty house. The Hudson-Hummels had gone camping for the weekend and had left the day before, and Kurt was grateful for the privacy and his ability to convince them to allow him to stay home alone.

"I'm not going to live for eternity, not like you. If we stay together, people are going to start noticing. I don't think I can be turned, not now that I'm already, well, like I am. What is going to happen when old age takes me and -"

Kurt shushed Blaine, placing his finger against his plump lips. "Don't."

"But -"

"Don't ruin this moment, Blaine," Kurt said firmly. "It's not as if I don't already know of all your fears, I hear them every day, feel your insecurities as if they were my own. But, please, let me enjoy our time together."

Blaine looked into Kurt's serious but pleading eyes, now much brighter than they had been only moments ago, and then relaxed with a sigh. He scooted down in the bed and tucked himself in against Kurt's side, allowing Kurt to wrap a strong arm around his waist. Blaine squeezed his eyes shut tightly and tried to will away his thoughts and clear his mind.

"I almost feel human again, when I'm with you," Kurt spoke just above a whisper. "At least, I think I understand what people are talking about when they talk about love."

"Kurt," Blaine breathed.

"Yes?"

"Never mind. It's just that -

A thunderous crash sounded outside, shaking the house and its foundation. Kurt and Blaine both sat bolt upright, Blaine's heart now beating erratically.

"What was that?" Blaine asked.

"Stay down," Kurt warned, leaping up from the bed to peer out the fogged window the best he could. Then he saw them begin to materialize through the curtain of rain, and he held his breath, becoming still as a statue.

There was a blinding light, and then something came crashing through the window, shattering the glass all around Kurt who instinctively ducked and shielded his face. He whipped around to see a terrified Blaine now crouching beside the edge of the bed, his breathing labored, poised as if ready to pounce if necessary.

"Run," Kurt hissed. "Go. Now!"
