My first slash fanfic, written purely for the sake of slash.

WARNINGS PLEASE READ!- I've made up a couple of things in here so if something isn't necessarily true just go along :)

Set around the time when Dean returns from Hell, he's told Sam and Bobby about Hell and about Alistair but they don't know Castiel yet.

ANOTHER WARNING! - Its a little bit disturbing so fasten your seatbelts and hold on to your buttocks :D

DISCLAIMER - This is a FANFICTION people! Kripke and all involve in the writing and making of Supernatural obviously would not write such a thing so yeah, that's me disclaiming all characters and events in the tv show featured in my fanfic

Thank you, and enjoy :)

"Sam, Dean, don't ever let a demon kiss you." Bobby told the boys as they sat opposite him. They had just finished a hunt so Bobby thought he would teach them a couple of things. "If a demon sets his sights on a human and bites their tongue..."

"What?" Dean raised his brow and stood up, stepping away from the chair as he looked at the old hunter.

"It'll kill you." Bobby said.

"What! Why, how?" Sam stumbled over his words. He'd never heard of a demon killing that way.

"Its a more pleasurable way to kill. If they are attracted or just...Look, I don't know much about it because it doesn't happen very often but..." Bobby stopped at the lights began to flicker.

"Hello, Dean." A familiar, haunting voice hissed in his ear and he froze. Sam stood up and he and Bobby stepped back, eyes wide and bodies at a ready stance to attack the strange man who appeared behind the young hunter. Dean's eyes flew wide open and his breathing became sharp. "So, you do remember me? I'm flattered." Alistair chuckled.

"Alistair..." Dean breathed.

Dean turned slowly and before he got all the way round Alistair's hand pinned him to the wall by his throat. Dean grunted and gripped the arm that restrained him. Sam and Bobby lunged for the demon with their knives and Alistair threw them back to the wall with a glance, pinning them to the wall with his invisible restraints. Alistair returned his attention to Dean, who looked up at the demon's face as fear tore through him. Images of Hell flooded through his brain and he trembled under the grip of the master torturer.

"I've missed you Dean." Alistair smirked and Dean shuddered at the sound of his name in such a terrifying tone.

"Wh-What are you doing here?" Dean's voice shook more than he cared to show.

"I wanted to see you." Alistair grinned. He stroked a finger across Dean's jawline and rested it on his chin.

"Well, the feeling's not mutual." Dean swallowed hard.

Alistair smiled in feigned sympathy and released Dean's neck. He knew he wouldn't go anywhere, he was too frightened.

"Why do you have such fear, boy?" Alistair stepped closer to Dean, who pressed his back against the wall as much as he could.

"Because you're a sadistic son of a bitch demon who tortured him for thirty years." Sam hissed from the other side of the room. Those words were hard for Dean to hear, but he had to face them sooner or later.

"But what about those last ten? Where we were the same, you and I?" Alistair leaned in closer to Dean, ignoring Sam.

"We're nothing alike." Dean growled, his anger giving him slight confidence.

"I beg to differ my boy." Alistair hissed and leaned in until his lips touched Dean's. Dean's eyes flew wide open and tried to pull his head away but it was against the wall behind him.

"Dean!" Sam cried.

Bobby watched in horror. He'd seen it before, just once, and it didn't end well.

Alistair deepened the kiss and forced his tongue into the hunter's mouth. Dean, feeling the intrusion, tried to push the demon away but Alistair was too strong and his frantic shoves were almost non existant to the demon.

The demon closed his eyes and leaned in closer to the kiss and Dean's eyes were wide with horror. Alistair pulled Dean's tongue into his own mouth and bit down on it hard. Dean grunted in Alistair's mouth as the pain shot through his tongue and blood began to leak out the side of his mouth.

"Dean!" Sam cried again. "Get off him!" Sam demanded, his voice shaking a little in fear.

Dean put his hands on Alistair's chest and frantically hit and pushed him, trying to get the disgusting demon off of him. Alistair smiled into the kiss and released Dean's tongue before shoving his own tongue into the hunter's mouth.

Dean's muffled screams just encouraged Alstair who bit down on Dean's bottom lip until it bled. The hunter trembled under his touch and his hands shook as he hit Alistair's chest desperately. The lights began to flicker as Alistair growled into the kiss and Dean's eyes were wide at the frightening noise. Alistair kissed Dean violently and dug his nails into Dean's sides as he fought to get away.

Dean cried out into Alistair's mouth as the demon growled and forced the kiss deeper. He grabbed the hunter's tongue again and bit down on another part of it. Dean's screams were muffled and the blood leaked out, more this time from the side of his lips.

"Dean!" Sam cried as he saw the crimson liquid seep out from his brother's lips.

"No." Bobby breathed in horror.

Alistair pulled away from the kiss and licked the hunter's blood from his own lips. Dean gasped as his mouth was free of the intruder and he breathed heavily.

"Til next time, my boy." Alistair cackled before he disappeared, in the blink of an eye.

Sam and Bobby were released and Sam rushed to his brother, who sank down to the floor.

"Dean!" Sam cried as he looked at his brother's pale face. "Dean, are you ok?" He asked quietly.

"I'm fine, Sammy." Dean said, breathlessly.

Bobby rushed beside the young hunter. "Let me see." Bobby said.

Dean frowned and poked his tongue out to show Bobby. Bobby leaned in and looked at Dean's blood covered, almost mutilated tongue.

"Oh, Lord..." Bobby breathed.

"What?" Sam looked at Bobby frantically.

"The venom's in. It's too late." Bobby told them, his face in pure terror.

"So what's gonna happen to him?" Sam cried.

"Eventually he'll become dependant upon the venom, he'll crave it like a vampire craves blood." Bobby sighed.

"And then?"

"Well if he gets the venom, he'll die. He'll crave the thing that kills him." Bobby sighed.

"How can we cure it?" Sam demanded, his voice still possessed some terror.

"I...I don't know." Bobby bit his lip.

"What'd you mean you don't know?" Sam cried.

"This hasn't happened in decades, demons don't usually kill this way because its too draining on them to produce so much venom."

"So...what'd we do?" Sam asked, his voice almost a whisper.

"I'll find a cure." Bobby nodded and rushed to his study.

Sam looked down at Dean. His older brother's face was almost blue, and the skin around his eyes was dark.

"Hold on, Dean." Sam said softly.

Dean looked up at his brother weakly.

Sam put Dean's arm over his shoulder and helped to lift the weak hunter to his unsteady feet. He helped Dean over to sit down on a chair and stood to face his brother.

Dean leaned back in the chair and breathed heavily. Sam grabbed a warm towel and wiped the blood from his brother's lips. Dean trembled as he stared blankly at the floor. Sam looked at Dean sympathetically. He'd never seen the young hunter this scared, by anything or anyone except Alistair.
