A/N: This story was initially meant to be a one-shot that turned into a multi-chaptered fic, and now I feel it's going to become something much more. For more details, check out the notes at the end.

Thanks again to the lovelies who have encouraged me along the way. It has been incredibly freeing being able to finally share some of my work in this setting. I will always be hard on myself, always questioning my abilities, but I hope this will only push me to improve and keep doing what I love for the rest of my life.

I would have kept you, forever

The moment Dean gave the word, Benny rested the sharp edge of the knife just below Sam's wrist, allowing it to slowly glide over his skin, a ribbon of blood following the silver metal. As the coppery scent filled the air, Dean was forced to take a step back, his brother's blood overwhelming his senses.

Sam hissed at the sensation of his skin splitting open. His eyes tracked Benny's movements as he set the knife by his jacket, just off to Sam's right. He watched the vampire's bloody palm lift towards his face, felt cold fingers grip his forearm below the cut. Sam's eyes flickered up, met Dean's heavy gaze, saw the hunger and self control riding on the brim threatening to spill over. Benny waited until Sam met his eyes once more, and before anyone could change their minds, he pressed his bloody hand against Sam's mouth. He noticed the young Winchester had tensed on reflex, and before he realized what he was doing, reacting off pure instinct, Benny released Sam's arm and placed his free hand just behind the younger man's ear cupping the back of his head.

Sam's eyes widened, staring as his heart jolted, startled. Benny practically felt Dean's presence behind him, didn't have to look to know he had shifted closer.

"Relax," Benny murmured, keeping his eyes locked on Sam but directing it to both Winchesters. "Just drink, Sam."

To his surprise, Sam immediately complied. Benny watched in fascination as Sam closed his eyes and began sucking the blood from his palm. Benny found his other hand drifting down from the back of Sam's head to his neck, overcome with the sudden desire to bite into the tender flesh.

Benny heard Dean this time. A low growl meant only for his ears emitted from his friend, and Benny blinked away from the expression on Sam's face. He hadn't meant to touch his closest, and only friend's younger brother like that, and knew he needed to finish this as soon as possible. Quickly removing his hand from Sam's neck, Benny grabbed his arm instead, lifting it to his mouth until his lips were placed along the cut in the young man's flesh and began to suck.

The jolt Benny felt once he and Sam were connected by the exchange of blood was electrifying, and clearly Sam reciprocated the sensation by the slight tremble Benny could feel underneath his skin. The moment passed all too quickly when Sam made a pained noise and Dean was there instantly, separating them. As Benny released Sam and stood so that Dean could crouch in front of his brother, mirroring Benny's stance, the older vampire found himself wanting more. But more of what, he couldn't be certain.

Dean gripped Sam's face with both hands, attempting to offer any type of comfort as Sam began to turn. Dean knew how overwhelming the transformation was, and as Sam squeezed his eyes shut as simple noises became almost too loud, as his sense of smell and self awareness became heightened, Dean held onto his brother, keeping Sam grounded until the intensity of the first stages passed.

Dean was a little surprised, but relieved, when Sam relaxed only a few moments later, seemingly calm, but his face still full of emotion. Dean recalled it being a longer ordeal before he was able to loosen up, and the older Winchester thought about what Benny had said, that him drinking Sam's blood would ease the transition.

Dean was grateful for the relief Benny had given Sam. And maybe there was also a pang of jealousy somewhere deep down, too, that it couldn't have been him providing that relief to his brother. He let it go, because Sam needed him now, more than ever, more than anybody else.

Finally, Sam opened his eyes, and Dean could see the fresh red tint lining his brother's irises. He could also see Sam's hunger.

For the first time since Dean had gently guided his brother to the bed, Sam turned his head to gaze upon the unconscious Amelia, a sorrowful craving in his eye. Dean took a hold of Sam's chin, slowly turning his brother's eyes back on him.

"It's okay, Sam. She won't feel any pain."

Sam nodded imperceptibly, his hungry and unsure eyes moving from Dean's to peer back over to Amelia. Rubbing his thumb gently over Sam's jaw in a comforting gesture, Dean released Sam and stood, moving away from his brother. He felt Benny close by, just over his shoulder, watching as Sam slowly moved from the bed. Dean watched his little brother carefully slip beside Amelia on the bed, as though he was making sure not to wake her. It made sense; Dean couldn't imagine Sam going through with this if Amelia woke up and started begging him to help her, to spare her life.

Sam started reaching for Amelia then stopped, seemingly afraid to touch her. He looked over at his brother and Benny standing only a few feet away. Dean allowed a small, consoling smile, while the older vampire gave a nod. Sam was taken aback to find that he was just as comforted by Benny as he was Dean.

Looking back down at Amelia, Sam focused his attention on her neck instead of her face. Ignored the familiar scent and focused on the new pieces of her that his senses were picking up on. Her steady heartbeat, how intoxicating the blood smelt just beneath the surface of her smooth skin, the gentle rhythm of her slumbered breaths. Ever so gently, Sam leaned over Amelia, using a hand to push back her soft hair, completely exposing the neck. Swallowing, taking in a deep breath, Sam cut off all of the conflicting thoughts rushing through his throbbing head, wanting to do this for Dean. His brother needed him, and now that Sam knew his brother was alive, knew what he was, he knew there was no way he could have left him even if he had chosen not to become a vampire like the elder Winchester.

Bending, allowing his cravings to take over, the senses directing his actions, Sam barely noticed the almost painful sensation of his new fangs descending as he closed in on Amelia, his sharp teeth piercing through her neck so easily.

Dean let out a breath he hadn't realized he had been holding. Again, nagging thoughts in the back of his mind tried to break through to the surface, accusations of what he and Sam now were, how it went against everything they were taught growing up, that he was selfish for asking Sam to become like him. At the same time, the relief that flooded through Dean as Sam took the final plunge like he had weeks ago was enough to drown out the antagonistic thoughts.

The older Winchester looked over his shoulder at Benny who was observing Sam feeding on his first human. Benny locked eyes with Dean, possibly unsure as to how his friend was going to react after the moment he and Sam had shared. He was relieved to see a soft look on Dean's face in place of an angry or accusing one.

"Thanks for sticking around, Benny," Dean whispered, not wanting to break Sam's concentration, "I…we couldn't have done this without you."

Benny gave Dean a familiar, relaxed grin. "Anytime, brotha."

Dean watched Benny for a moment, part of him wanting to ask about what happened between him and Sam, if it had been something more than just a shared feeding, but he chose to simply give Benny a nod before focusing back on his little brother. He had more than enough time on his hands now to bring up that conversation with Benny if he ever felt the need to.

Leveling his eyes back on Sam, Dean noticed that his brother was being careful not to actually touch Amelia. Both hands were gripping the bedding on either side of her, knuckles white. Dean could hear her heart slowing, knew it was almost finished when Sam pulled back with a sudden sob, blood smeared over his mouth. Dean wanted to tell him to finish, but the pleading look in Sam's eyes stopped him.

"Dean, I can't," Sam moaned as he fell to the ground in between the beds, his long legs pulled up, knees close to his chest.

Rushing forward, Dean knelt beside Sam, resting a hand on his knee. "It's okay, Sammy. You don't have to. You did good; I got this now, okay?"

Sam gave Dean a grateful nod, eyes wet. Grimacing as Amelia's blood flowed through him, completing the change, Sam lowered his head, arms resting on his knees as he let his hair fall in front of his face. Dean didn't want to leave his brother's side, but knew he needed to finish what Sam had started like he had promised. Sam had just given him everything, and now Dean needed to do this for his little brother, secretly hoping Sammy would never resent the fact that his brother had killed someone he claimed to love.

Dean shifted to look back at Benny, who had stayed frozen in place, unsure of what he should do. He noticed that Benny had tensed, like he was fighting with himself, and Dean realized Benny had wanted to come forward when Sam had collapsed on the ground but was preventing himself from stepping forward. Dean knew Benny felt some kind of connection with Sam now, but instead of letting himself begin to question it, he focused on the fact that he needed Benny's help. He reminded himself this was his friend, his brother in arms, the man who helped him escape Purgatory. He trusted the vampire, and if Benny was suddenly feeling protective over Sam, instead of feeling threatened by him as a hunter, who was Dean to complain.

"Benny," Dean gestured him over, and the tenseness in the vampire's body seemed to melt away as he moved forward without hesitation. "Just, stay with him."

"Sure thing," Benny murmured, lowering himself onto one knee beside Sam, placing his hand on the same spot where Dean's hand had just been.

Without wasting any time, Dean moved away from his brother and Benny and gathered the barely alive Amelia into his arms. Using one knee to balance himself partway onto the bed, Dean buried his fangs in the same area where Sam had just been feeding and drank. He savored the taste of fresh, warm, human blood, unwilling to admit out loud just how much more appealing it was to animal blood or the cold taste of old blood from an IV bag. Draining the woman quickly, satisfied as the lethargic heartbeats stopped, Dean pulled away from the already cooling body, placing her gently back down on the bed. Licking away the final drops from his lips, Dean turned back to the other two still sitting on the ground. Benny had placed a comforting hand on the back of Sam's neck as he had finally relaxed, and his little brother slowly lifted his head to lock eyes with Dean. The red tint was gone, his brother seemingly calm and steady, and Dean smiled at the familiar trust in Sammy's eyes. As Benny looked away from Sam and focused on his friend, Dean felt a surge of contentment he had not felt in a long time.

Besides the complications their new lives brought, the stresses they were sure to face, the issues of Crowley, Kevin, and everything else, in this very moment, didn't matter. Dean had his brother now, and everything that could have gone wrong that night worked out better than he had hoped. Even if it only lasted a few seconds, everything was perfect. No matter how short it lasted, Dean was going to relish it for as long as he could. Smiling down at his family, Dean closed his eyes, feeling, if only for a second, peace.

End A/N:

Without meaning to, I have become fascinated with the connection I sparked between Benny and Sam in this fic, and am intrigued to explore the relationship between these two and Dean in a much longer story. I feel like Run Away, I'll Attack, will become something of a prologue to another piece I plan on writing to continue what I started.

For those who stick with me, I hope not to disappoint :) Thanks for reading.
