Summary
     Dean gets bit by a vampire and goes to the only person he can, his
     best friend Sam. The only problem? Sam's blood smell amazing.
His blood was pounding in his ears, every noise was too loud, all the lights
were too bright. He covered his head as he walked down the dark alley, trying
to avoid people. He had to find Sam, had to get to him. His best friend was
always so smart. He would know what to do.
Halfway down the alley Dean turned as he spotted Sam’s house. He walked up to
the back door and considered just going in, but what if the boy’s parents were
awake? He looked around and after a moment decided to climb up a tree. It was
easy, so easy, and he jumped from the tree to the landing outside of Sam’s
window. It was open a crack and he pushed it up the rest of the way, climbing
inside.
Looking around he saw that Sam wasn’t in the room, but he wouldn’t be gone
long. There was a book open on his bed, one Dean had saw him starting earlier
that week. Little nerd was already almost done with it. Under any other
circumstances Dean would have laughed, shook his head fondly. Instead he sat on
the edge of the bed and buried his face in his hands, trying to get his blood
to stop rushing, his heart to stop pumping so hard and fast.
The bedroom door opened and Dean heard a sharp inhale. He looked up to see his
best friend standing in the doorway, hand covering his heart. “Holy shit, Dean.
You almost gave me a heart attack.”
“Sorry,” Dean croaked out, “I didn’t know where else to go.”
Sam closed his door and moved over to Dean. “What’s wrong?”
The older boy looked up and knew that Sam saw his bloodshot eyes when his own
went wide. “Are you high?”
Dean laughed bitterly. “I wish.”
Sam sat down next to him, too close, and without thinking Dean breath in,
taking in the other boy’s scent. He could hear his blood, smell it, and damn if
that wasn’t the sweetest thing he’d ever smelled in his life.
He jumped up, moving quickly across the room. “This...this was a bad idea.
I...I’m...Oh god, Sam. I gotta go.” He moved for the window, but Sam got up
quickly and grabbed his arm.
“Dean, what wro-”
Before he could finish Dean had turned. He pushed his best friend up against
the wall and leaned in, face pressed close to his neck, inhaling deeply. He
shuddered at the scent and let out a soft groan.
“You smell so good, Sam…”
“Wh-what?”
Sam’s heart was beating faster, hands at his sides, body rigid. Dean quickly
pulled away, backing up, stumbling toward the bed.
“Sam, I got bit.”
The younger boy’s eyes widened. It was no secret between hunters that there
were vampires in the city, so there was no doubt that Sam knew exactly what he
meant.
“It...It’s okay, Dean. We’ll figure it out.”
“No!” Dean saw Sam flinch and he closed his eyes, taking a deep breath through
his mouth to calm himself. “Sammy, no. I can’t...You gotta take care of me
before I hurt someone.”
“I’m not gonna kill you, Dean!”
Dean’s eyes snapped open. “Sam, if you don’t I’m afraid I’ll kill you.”
“You won’t,” Sam replied easily, “I know you. I trust you.”
“I”m not gonna be me, Sam,” Dean insisted, “Just now I was...I wanted to bite
you.”
“So...so go ahead,” Sam said and Dean’s eyes widened, “I’m not asking you to
change me, or kill me. Just...let me satisfy your craving. I trust you. You’ll
stop.”
“Sammy, I can’t do that.” Dean was moving toward the window again, keeping a
careful distance between himself and the boy.
Before he got to the window though, Sam pulled his knife from his sock, opened
it up, and sliced his arms. The smell wafted to Dean, up his nose, and he let
out a strangled moan, body going stiff as he tried to stop himself.
“It’s okay,” Sam said softly, moving closer to Dean, bringing his arm to the
older boy’s lips.
Dean couldn’t resist, not when it was this close. He grabbed Sam’s arm and
closed his eyes, sucking hungrily. His knees shook with the pleasure and he was
startled to hear a little whine escape Sam’s throat as he threaded his fingers
through Dean’s hair, holding his head in place.
Growling Dean pushed Sam back toward the bed and crawled on top of him. He
pinned his arm to the mattress and sucked harder, pressing his hips down
against Sam’s, cock hard in his jeans. Sam’s own hips pushed up and they
started rubbing against each other, breath coming heavy and uneven.
This was all very new and unexpected, but Dean didn’t care. It felt so good and
he wouldn’t last. Sam tasted incredible and his moans were the prettiest thing
the older boy had ever heard.
It really didn’t take long. Dean was the one who went over the edge first,
sucking more desperately as he came, groaning. Sam bucked his hips and choked
out a moan, coming moments after Dean.
The older boy slowly pulled back, lips and teeth stained red from the blood.
“That was so stupid,” he whispered. “You shouldn’t have done that.”
“You stopped,” Sam pointed out.
Dean rolled his eyes and leaned in to kiss his best friend, not caring that his
had blood in his mouth. Sam wrapped his arms around him. “We’ll figure it out.”

“Yeah, yeah,” Dean sighed, “i know.”
