A/N: Vampire AU. Angst. Warning for biting, mention of blood-sucking, romance. I don't want to say too much…

"Kurt…"

Kurt can hear the eerie hiss of Sebastian's voice through the closed window of his room. Kurt lies completely still, hoping that Sebastian will think he's asleep and go away.

"Ku-urt…"

It doesn't work.

It never does.

Kurt sighs and turns towards the window. Sebastian's eyes peer in at him in the dark, the rest of his face shrouded by the shadows of the branches from the tree he crouches in outside.

"Go away, Seb," Kurt groans.

"I can't," Sebastian whines, pressing his hands and face against the glass of the locked window. "I want it, Kurt. I need it."

"Sebastian," Kurt says firmly, his tired eyelids fighting to stay open long enough to get rid of his obnoxious visitor, "there are hundreds of men in the state of Ohio who can give it to you."

"But I want you," Sebastian insists. "You're the best."

"Be that as it may, you're not getting any." Kurt turns his back to Sebastian an attempt to hide his triumphant grin.

The best.

What a tacky thing to be proud of, but he'll take what he can get.

"Oh, don't be such a prude," Sebastian grumbles sarcastically. "You know you love it, too."

Kurt spins around in his bed, sitting upright to better face the boy hovering by his window.

"What a morbid thing to say," Kurt says. "I certainly do not."

"Don't give me that shit," Sebastian groans. "I know you, Hummel. In some ways, I know you better than you know yourself. I've tasted you…"

Sebastian smirks at Kurt, and Kurt burns red, his whole face hot to the touch. Kurt retreats to the safety of his comforter, wrapping it around his shoulders, trapped in Sebastian's hypnotic stare.

"I know it turns you on. I hear the way you whimper," Sebastian continues, tracing down the pane of glass with a single, thin finger. "I see the way you bite your lip, trying so desperately not to moan…"

Kurt's eyes track Sebastian's fingertip as it outlines the edge of the glass, stopping on the ledge where the lock to Kurt's window is fastened shut, tapping right above it as if he is simply waiting out the inevitable.

Sebastian isn't wrong. Ever since the first time Sebastian convinced Kurt to do it, Kurt realized he's kind of a masochist as far as Sebastian is concerned. Even now as he tries so hard to resist he can feel his heart pounding faster and faster in his chest, longing to give in, to give Sebastian what he wants. Regardless of his heart's begging to let Sebastian have him, or his body that's begun to react without his consent, Kurt isn't just about to lay himself bare for Sebastian

He doesn't want to make it too easy.

"My answer is no, Seb," Kurt says again, snuggling down onto his bed and closing his eyes.

"Fine," Sebastian growls, feral and threatening, all pretense of slow, sophisticated seduction gone, "Kurt Elizabeth Hummel, if you don't open this window right now and let me in, I'm going to start singing Spice Girls songs at the top of my lungs all night long."

That definitely gets Kurt's attention, exhausted or not. Kurt pops up in bed and meets Sebastian's burning glare with an icy stare of his own.

"You…wouldn't…dare," Kurt challenges, but the second Sebastian opens his mouth to start singing, Kurt runs to his window in a flash, undoing the lock and pushing it open before a single word of Wannabe leaves his lips.

"Won't you come on in?" Kurt gestures dramatically, not even trying to hide his irritation. Sebastian climbs through, grinning from ear to ear. Sebastian closes and locks the window behind him, following Kurt as he trudges back to bed, trundling beneath the comforter with a single arm sticking out.

"Get on with it," Kurt says. "I have a calc test in the morning and I want to at least get an hour of sleep."

Sebastian looks down at Kurt, wrapped in his blankets like a human burrito, and frowns.

"As sexy as this is," Sebastian mutters, moving to the other side of the bed and climbing beside the bundled body of Kurt Hummel, "I would really like to hold you."

Kurt peeks up from a space in the comforter and sighs, pulling apart his carefully wrapped cocoon to let Sebastian crawl inside. Sebastian winds his arms around Kurt, trying his best not to hold him too tight. He doesn't want to accidentally hurt him. He takes Kurt's arm and raises his wrist to his mouth, kissing the soft skin, pressing his lips against it to feel the pulse thrumming there, calling to him.

"Do you miss it?" Kurt hums, enjoying the cool press of Sebastian's lips against his skin.

"What?" Sebastian asks taking a deep breath of Kurt's scent – vanilla and honey, sweet and floral, delicate and human.

"Being alive?" Kurt mutters, looking up into Sebastian's pale face and his hard, red eyes; eyes that were once such a beautiful shade of green.

Sebastian smirks, running his lips along the inside of Kurt's forearm, tracing the paths of his veins with a gentle lick of his tongue.

"Not as long as I have you to remind me," Sebastian whispers. Kurt closes his eyes as Sebastian places open mouth kisses along his skin.

Kurt has long since stopped being fascinated by this part.

The bite is quick; a smooth slip of Sebastian's razor sharp fangs into Kurt's skin, and suddenly his mouth is filled with Kurt's unique taste, his mind reeling with images of warm summer walks they shared together, skinny dipping in the lake, late afternoon lunches of Kurt's famous cucumber sandwiches, and making love at sunset, brazenly beneath the tall willows that grew just shy of the water. In this way Sebastian can remember exactly how Kurt's skin felt with mortal fingers, the warmth of his body pressed against his, the way they fit perfectly together, like two pieces in a puzzle that was once the picture of a glorious future together.

One stupid fight and a vengeful, drunken tryst ended it all when the vampire who seduced him turned Sebastian into the cold, dead thing sucking the blood from his one true love's arm.

Sebastian breaks away, tracks of bloody tears staining his cheeks, and with a swipe of his tongue he closes the wound. He looks down at Kurt, eyes shut, his face peaceful in sleep beneath the silver light from the moon outside. It's been a little over a year, and yet it feels like only yesterday, but Sebastian knows that a time will come when days and nights and months and years will have no meaning for him at all. One moonlit evening he'll be here and Kurt will be vibrant and alive, and in the blink of an eye seventy years will pass and Kurt will be gone.

Sebastian only hopes that when that day comes he'll be able to find the courage to walk out into the sunlight.

He pulls in closer to Kurt's sleeping body and rests his head where he can hear the rhythmic beating of his heart, and as he has so many other nights, he lies awake with Kurt in his arms, dreading the oncoming dawn.
