Sebastian ran his finger down the worn, yellowed pages of the spell book, checking one last time that he has everything right. Hed been dabbling in dark magic for some time now, but this would be the biggest spell hes ever tried to pull off. And if anything goes wrong he knows his life will be forfeit. 

Sebastian grabbed the knife and held his hand over the stone bowl he placed in the middle of his alter. The candles around the bowl flickered as he sliced into the palm of his hand and let the blood drip from his veins to the bowl. He was summoning a demon, that always meant the use of blood. 

Sebastian chanted the ancient words from his book of black magic and soon the alter began to shake. The air in his basement grew cold and a strong wind started whipping around him. The candles went out and Sebastian was left in almost complete darkness, the only light coming from the moon that streamed in for the high windows in the back of the room. Suddenly, the wind and shaking stopped. 

Before Sebastian loomed a dark shape, taller than any human man. As Sebastians eyes began to adjust to the darkness, the figure took a step forward until it was standing in the path of the moonlight. Sebastians breath cought in his throat. 

The creature was huge, at least 7 feel tall, with dark leathery looking skin, and massive wings folded behind its back. He had two sets of arms and legs and four heads. One head was larger than the others and sat in the middle. The demon stared, unblinking, at Sebastian, its mouth partially open and saliva dripping from its fangs. 

Sebastian swallowed and tried to control the waver in his voice, "Asmodeus." He breathed. 

The demon lifted its heads back and studied Sebastian before he started to speak, his voice coming from the large head in the middle. "Who are you to call upon me? All who do so meet with death." 

The demons voice was low and gravelly and sent a shiver through Sebastian. He curled his hands into fist to keep them from shaking. The demon was bluffing, or at least if his book was correct the demon was bluffing. 

"I know what you want." Sebastian said in a falsely confident voice. "You desire human souls, And I... I have a proposition to make."

"What stops me from taking your soul now?" The demon stepped forward a towered over Sebastian. 

"Because I know. I know how you work. You want a soul that is innocent, but consumed with sexual desire. You need them to want sex so.. so much..." Sebastian cleared his throat. "Theyd die for it."

The demon didnt respond, so Sebastian continued. "I brought you here, you were cast out of the realm of men and I brought you here, and I have a gift for you."

The demon just tilted his head, "A gift?" 

Sebastian nodded and picked up a picture from beside his spell book, handing it to Asmodeus. The demon blinked all of the eyes on each of his heads and looked at the picture. 

"His name is Kurt." Sebastian said. "And I want you to have him." 

*********************
Sebastian watched Blaine smiled and flirt and stare sickeningly at Kurt as they talked and drank their coffee. It made Sebastian feel sick. What the hell did Blaine see in him anyway? He could do so much better. No matter. Sebastian thought, it wont be long until Kurt is out of the picture. He waited until Kurt got up to use the restroom before he moved from the back of the room and approached Blaine. 

"This seat taken?" He asked with a smirk and didnt wait for Blaine to respond before he sat down in the chair Kurt had vacated. 

"Sebastian." Blaine said and sighed, he seemed annoyed. "What are you doing here? Why are you always here? Cant you just leave us alone?"

Sebastian smiled. "I thought we were friends?" 

"You threw a rocksalt slushie at me." Blaine deadpanned. 

"In my defense, that was for Kurt."

Blaine narrowed his eyes and lowered his voice, he was actually angry. "That makes it worse." 

Sebastian laughed and Blaine glared at him before glancing towards the restrooms to see if Kurt was coming. Sebastian took the moment to slip something into Kurts drink. Asmodeus had given Sebastian some of his saliva, it would infect Kurt starting at midnight, and the demon promised that very, very few survived it. Kurt would be dead by the next midnight. 

Sebastian stood as he saw Kurt heading back to the table. He looked down at Blaine and winked at him. "See you latter charmer." He said and walked away. 

*********************
Kurt watched Sebastian wink at his boyfriend, as he strode over to the table and down across from Blaine. "What did he want? Trying to blind you again?"

"I dont know. He said something about us being friends."

Kurts eyes widened. "Are you serious?"

"I corrected him, Kurt. Dont worry Im not going down that road again."

"Im not worried about that." Kurt said and took a sip of his coffee. "I just... I dont like him."

Blaine smiled and grabbed Kurts hand across the table. "Dont even worry about him. He isnt important."

Kurt squeezed Blaines hand and finished his drink. They left The Lima Bean a little while latter and Blaine drove Kurt home. 

The whole rest of the evening Kurt felt a little... off. Tired and achy, maybe he was getting a cold.

He went to be early and tossed and turned in his sleep. When the clock by his bed clicked to midnight Kurt began having vivid, colorful, erotic dreams. He wouldnt be able to remember them in the morning, but they were full of smooth skin and warm lips, and deep desire. At one point there was a flash of wings, but it meant nothing to Kurt. 

He woke up the next morning more tired than when he went to sleep. His body was covered in a fine sheen of sweat and his body ached. Kurt groan and sat up. He hissed and the threw the covers off of himself, he looked down to see that he was fully hard and aching. 

Kurt groaned and tilted his head back on the head board of his bed. He then reached a hand into his pants to take care of the problem when a cold air filled the room. Kurt felt like he wasnt alone, but when he looked around no one was there.He reached his hand around his erection and was about to start pumping, when he blacked out. 

Suddenly he was standing in a dark, dank basement with little light. He looked up and a huge creature was standing in front of him, it was terrifying, but somehow Kurt wasnt afraid. 

"I am Asmodeus, and I am here to claim your soul." His deep voice echoed around Kurt, making him feel dizzy.

"You have until tonight, when the chime hits midnight. If you can resist your desire until then, you have defeated me and I go back to the darkness." 

Kurt was shaking and gulping now, fear finally catching up with him. 

"But if you give in to the pleasure of your desire than you forfeit your soul to me. You will be mine." The voice took on a deep longing sound that made Kurts skin crawl. 

"You have until then to try and keep yourself alive."

With that Kurt fell backwards, subconscious. He awoke in his own bed, trembling with fear and need. His hand was still lightly wrapped around his hard cock. Kurt gasped and pulled his hand put of his pants.

"Oh my god." Kurt said and got up from his bed on shaky legs. "Oh my god, oh my god." Kurt was scared, but also needy his hand started working its way down his stomach to his pants again before he snatched it back. "Oh my god! What am I going to do?"
