Chapter 2

Sam struggled to get Dean into the room. Dean cried out in pain as they hobbled to the door, Sam braced Dean against the frame as he opened the door and attempted to get his brother over to the bed."Shh, baby, it's ok, I'm here." Sam tried to stroke Dean's hair as he watched his brother arch up and contort into painful looking positions on the bed.

"God, Sam, hurts, uh, hurts so much." Dean choked out, his fingers clawing at the sheets, his knuckles turning white.

"I'm calling Bobby." Sam picked up his mobile and dialled. He turned away from the sight of his brother shuddering in pain but he could still hear him panting and crying out, and that brought tears to his eyes. Sam dropped the phone and raced to his brothers' side as Dean let out a blood curdling scream, trying to pin him down as Dean thrashed. "Dean no, look at me." Sam pleaded and pain glazed eyes managed to focus on him. "That's it, stay with me." He begged, holding Dean's hand, able to feel his pulse slowing. "Don't leave me baby." He whispered and Dean raised his hand to Sam's face before his heart stopped and he died in Sam's arms.

Sam knew what he had to do as a hunter but it was Dean. He couldn't do; he couldn't kill Dean. He also knew that if he wasn't going to kill Dean then he should at least move away, make himself less tempting a snack when Dean woke up but he couldn't, he stayed where he was, cradling Dean's cooling body in his arms until Dean twitched. "It's okay Dean, you're safe. I've got you baby." He whispered, hoping Dean would recognise his voice. Bloodshot green eyes opened and then Dean's lips parted, revealing a full set of vampire teeth. "Dean?" Sam fought to keep his heart rate under control when Dean growled softly, knowing a racing heart would just excite the new vampire. "Dean it's me, Sammy, please talk to me." He pleaded.

He growled as he opened his eyes, it smelt so good. He wanted it! He lunged up but his prey managed to get away and he crouched, growling.

Sam twisted away and off the bed as Dean attacked, putting the bed between them as Dean crouched and growled at him. "Dean it's me, it's Sam. You don't want to do this Dean, please baby." Sam whispered but there was no recognition in Dean's eyes. Why didn't Dean know who he was? Sam dodged another attack but then went down under Dean, struggling to keep Dean's teeth from his throat. He got a leg between them but he didn't want to kick Dean off, it would just piss Dean off further. "Dean please, it's me." Sam begged, managing to move his hand to touch Dean's face, trying to get through to him. Dean snapped at him, forcing Sam's arms down, going for his throat and Sam winced but moved his head, meeting Dean's mouth with his own. He felt Dean's teeth in his lip and it hurt so much but Sam forced himself to ignore it, he'd had worse in the cage. Instead he kissed Dean with everything he had, trying to break through to his brother.

He almost had it and then warm liquid seeped into his mouth and he swallowed but there was something else too and it felt good, familiar somehow. He relaxed as he got what his body needed even if it wasn't a lot and everything began calming down around him so he stopped growling and relaxed a little.

Sam felt Dean relaxing so he slowly pulled a hand free and moved it to gently stroke Dean's side. Dean growled in warning but Sam kept the touch gentle and Dean stopped. Sam just kept petting and kissing Dean while Dean drank and lapped at the blood coming from Sam's lips. Dean finally pulled back, licking his lips and Sam waited to see what he'd do. Dean sniffed at him but didn't go to bite him again so Sam relaxed a little. "It's okay Dean, I'm here." Sam whispered and Dean frowned in confusion before his eyes widened in shock and horror.

"Sammy." Dean choked out in terror as he saw Sam's bloody lips. Dean scrambled off Sam and away, crouching in the corner as he stared at Sam in horror, watching his younger brother slowly sit up and go to wipe his lips only to wince in pain. "Sam?" Dean whispered and Sam got up, trying to move closer but Dean growled and then winced. Why had he growled at Sam?

"It's okay Dean, just relax." Sam whispered, ignoring the pain in his lips in his need to help Dean calm down.

"What have I done?" Dean whispered in horror.

"It's alright Dean, I'm not hurt. It's okay." Sam assured him but Dean could see the fresh blood seeping out whenever Sam moved his lips but worse, he could smell it and he wanted it so badly!

"Sam what? I…" He was so confused, how could he have hurt Sam? Had he hurt Sam or had someone else? Dean shook his head and then touched his own lips, hand coming away red and then he felt them, vampire teeth covering his normal ones. "No, no, no." He stared at Sam in dismay and Sam stretched out a hand to him.

Dean backed away, he was shocked at how fast his body could move now, and his senses were on fire. The dim lights of the motel lamps burned his eyes; he put a hand across them, in an attempt to shield them.

"What's wrong Dean?" Sam asked from across the room. Dean ignored him and continued to pace. He could hear...everything. He could hear the couple four rooms over going at it; he could hear the traffic several blocks away. All of it was pounding away in his skull; he covered his ears and dropped to the ground. He cried out again as his eyes were hit with the light again. But most worryingly he could hear Sam's blood, his heartbeat. "Dean, please you're scaring me." Sam took a step forward.

"No! Don't move, I've done enough damage already, I won't hurt you again," Dean held his hand up to stop Sam from moving closer.

"Dean, let me help you." Sam bit back his tears. He could see that everything was overwhelming Dean's newborn senses and there was nothing he could do to help.

"Sam no, please you smell, too...your blood, I…" Dean wiped a hand across his face. "No, it's best for you to stay there," he couldn't even look at Sam, partly out of shame and partly he didn't trust what he would do to him in this state.

"Dean, it's not your fault, you're hungry, what you did, it wasn't you." Sam watched as Dean flinched and backed away, into a corner, his head in his hands. Sam was tempted to bite his lip, out of habit but he soon remembered his wound and fought against the urge. The plus side to a vampire attack, they have a natural healing agent in their saliva so Sam's lips had already begun to heal. He took a step forward, he knew the risks, not only was Dean a vampire but it was Dean and he had told him to do something, he would be pissed that Sam was doing this, but his brother needed him.

"Sam, please." Dean whimpered. Sam put a hand gingerly on Dean's shoulder, when Dean made no attempt to move Sam took that as a sign that it was ok for him to be there. Easing himself to a sitting position he gently pulled Dean so that his brother was in his lap, cradling him in his arms.

"I'm here, I'm here." He rocked Dean a little. Dean pulled back a little before giving in and letting Sam comfort him. Although he had to stop breathing, it was the only way he could control the undeniable thirst that burned the back of his throat.

"Sam," he choked out "Sam, you have to…" Dean pulled back and allowed himself to look up into Sam's eyes.

"What Dean, what is it?" Sam eyes were wide and full of something, hurt maybe or hope.

"You have to kill me." Sam pulled away from Dean and stared at him.

"No." he said with a fierce determination. It reminded Dean of when Sam was a toddler. As soon as he had learned the word 'no' it had been his answer to everything. Dean could still remember the chubby, shaggy haired version of his brother when it came to bath times. Dad left it to Dean to bath Sam, but Sam would stand their naked, his cute chubby arms folded, and a frown on his face with a steely look in his young eyes. Dean smiled at the thought.

"You're so cute Sammy; remember when I used to bath you?" Dean croaked out, his own voice still unfamiliar to him. Sam was taken by surprise, and then he too broke out into a smile.

"Yeah, as I recall I hated them, used to tell you no way," the brothers took a moment to remember better times "Should have taken all the opportunities I could to see your amazing body." Sam grinned. Dean smiled.

"Now, you want to be kinky now?" Dean shook his head. "Seriously Sammy, you have to do this before I hurt anyone, or you." Dean told his brother calmly.

"No, there's another way." Sam cupped Dean's face softly.

"No there isn't," Dean ran his fingers gently along Sam's. "You have to do this, or I'll find another hunter who will."

"Dean, please, at least try, remember the nest of vamps we helped a while back, you saw that they were different." Sam pleaded, the tears running down his cheeks "You helped them, please Dean, try!"

"Sam, I can't be around you like this, it's too hard, you don't know how good you smell, how your blood tasted, I…" Dean licked his lips "This is the best way, I promise." Dean moved away from Sam again.

"So you won't even try, you hate me that much." Sam stood.

"Baby, I'm doing this cause I love you." Dean rose also.

"No, because if you loved me you would try, this is so typical of you Dean." Sam yelled.

"What?" Dean stared at his brother.

"Just because you think there's something wrong with us, you're running away, you always do this, something you can't handle you leave, it's always been like that, you're just like dad." Sam spat.

"Oh and you never have!" Dean growled "I recall a certain selfish bastard running away to Stanford, leaving his family and not looking back, you wouldn't even be here if I hadn't asked for your help!" Dean clenched his fists, he could feel the bloodlust rising in him, he turned and took a breath.

"I had no choice and you know it." Sam screamed "I wanted to stay with you guys but I also wanted a life Dean, I wanted to be praised for getting into college, but dad wouldn't let me!"

"Well now you can have that life you want, kill me and nothing will be standing in your way." Dean instantly regretted the words. Sam looked at him as though he'd been slapped.

"Dean," he whispered.

"Sorry, I didn't mean that." Dean wanted to reach out to Sam but he couldn't.

"I love you, I've always loved you." Sam sat back on the bed, defeated.

"I love you too Sammy, that's why I can't live like this, I can't risk losing control around you." Dean felt his heartbreak with Sam's next words.

"And I can't kill my only brother and my soul mate." he looked up at Dean.

"Don't worry Sammy, you don't have to." Dean used his speed to plant a kiss on Sam's forehead and run from the room before Sam could move.
