"It's time for the mark to have some fun", Dean purred, running his free hand down y/n's throat as she struggled to get him to let go of her hair. "It's been too long since I felt you." Dean's finger traced over her collar bone and down into the front of her pajama top. "I fucked so many women, y/n. So many women that looked like you." His hand slid back up to encircle her throat again.
"Dean, please!", y/n whimpered through her sobs. "Please don't do this!" She glanced over at Sam and his eyebrows twitched. Dean stared down at the tender flesh he was stroking with his thumb, ignored her begging, and continued as if she hadn't spoken.
"And I killed them because they weren't you." Dean pulled her close and stuck his nose in y/n's hair. He breathed in the sweet smell of her strawberry shampoo, remembering how he would bury his face in her hair when they made love so he could have that scent in his nostrils when he came. He wanted that again. He was abruptly pulled from his fantasy by a groan from the other side of the room. Dean looked up to see Sam writhing against the pillar and pulling on the rope. He jerked y/n along by the hair as he walked toward his brother, sitting on the floor.
"It's about time you woke up!", Dean grumbled. "I was afraid I'd have to start the party without ya!" Sam looked up at his brother, slack-jawed, and the one eye not swollen shut became as big as a dinner plate.
"How'd I get here without you knowing about it?", Dean interrupted. "I'm not as dumb as you think I am, Sammy. I knew you'd hack into my cell account and activate the GPS. That's why I left my phone in the motel room." Dean tapped his temple with a knowing grin. "I'm your brother, Sam. I know how you think." Dean yanked y/n over to the map table and through her down over it on her belly, holding her there by the tight grip he had on her hair. He rummaged through the duffel again and brought out a set of hand cuffs this time.
"Dean! Please don't hurt her!", Sam croaked. "You love her!" Dean chuckled, nodding his head as he cuffed y/n's hands behind her back.
"Yeah! And imagine my surprise when I come home to find my own brother on top of her", Dean snarled, yanking y/n up off the table. " TRYING TO FUCK HER!" He threw her to the floor in front of Sam. Y/n landed on her stomach, knocking the wind out of her. She could do nothing but lay there, coughing and gasping for air.
"Please stop this, Dean! This isn't you!" Sam jerked and pulled at the bindings, but he knew that Dean's knot tying skills were above par. He knew it was pointless. Dean walked over and knelt down next to his brother and pulled the bone blade from the back of his pants. He dragged the back of the blade down the side of Sam's face, letting the sharp teeth scrape along his cheek all the way down to his chin. Sam cringed trying to turn his face away.
"You're right, Sam.", Dean whispered close to Sam's ear. "It's not me. It's the mark. I can't control it." The blade continued it's path down Sam's throat and stopped at his collar bone. "But, I'll tell you something, Sammy." Dean pushed the tip of the jawbone into the flesh over his clavicle until he hit bone. Sam gritted his teeth to keep from screaming. "I don't want to control it anymore. I'm done fighting it. I've even embraced it." He twisted the knife, feeling the tip dig deep into bone. Sam couldn't hold back his scream any longer and it echoed through the bunker.
"Nooo!", a small voice sobbed from behind Dean. "Please, D!" Dean pulled the knife out of Sam and turned his head to look at y/n over his shoulder. She was staring at him with large eyes that glistened with tears. "Please come back to me, Dean. I love you!" Dean stood up and walked over to her and stopped. He looked down at her with an expression that chilled her to the bone. It was lust. But not the kind of lustful gaze he usually gave her. It was the kind of lust that a starving lion would give to an injured gazelle. Y/n gasped and tried to push herself backwards across the floor with her feet. But she only got a foot or so away before Dean pounced on her, pulling her beneath him, and straddling her hips.
"I AM back, Babygirl", Dean purred softly. He untied y/n's robe and pushed it down over her shoulders, watching her chest rise and fall with every harsh breath she took. He ran the blade lightly down between her breast and smirk at the fact that she wasn't wearing a bra. He continued his path with the blade down over her stomach until he reached the hem of her night shirt. It had ridden up when he pulled her under him and he licked his lips when he saw her belly button peaking out at him. He lifted her shirt and stuck the pointy-toothed tip of the knife down into that cute puckered hole in her belly and glanced up to see her reaction. She gasped again, panting harder while she stared up at the ceiling. He twisted the knife gently and y/n whimpered and squirmed under him. The mark was tingling as it heated up. It was enjoying this foreplay immensely.
"DEAN, STOP THIS!", Sam snarled. "PLEASE!" Dean leaned down close to y/n and grabbed her chin, turning her face toward Sam. He pushed the tip of the knife harder, breaking the skin. Y/n screamed and Sam cringed at the heartbreaking sound. Dean pulled the blade from her navel and slid backwards to lap up the blood before it could run down her waist. Y/n shivered as he sank his tongue into her belly button. All the time, keeping her face turned toward Sam. When he sat up and looked over at his brother, Dean smiled. The blood running down his chin and staining his teeth nearly made Sam vomit. Dean wiped his chin on the back of his hand and then licked it clean before sliding back up to sit on y/n's hips again.
"Well, it's time to get this party started", Dean said to himself, picking up the blade again.
"N-noooo", Y/n wailed, trying to wiggle out from under him. Dean grabbed the hem of her shirt and tore through it with the first blade. He whistled as he worked, meticulously cutting through her clothes until she was completely naked underneath him. The whole time, Sam is cursing him and begging him to stop all at the same time. Dean thought that Sam never looked so pathetic in his life.
"Ain't she pretty, Sam?", Dean panted, running the flat of the blade over a nipple. "Her hands cuffed behind her back really makes her beautiful tits stick out!" Sam looked away, breathing hard with rage. "Huh-uh, Sammy!", Dean called out in a sing-song voice. Sam heard a gasp and his head shot up in time to see Dean pushing the first blade into the side of her breast and watching her blood slowly roll down to the floor. He looked up and Dean was watching him intently. "If you look away again, Sammy, I'll do more than poke a little hole. Got it?" When Sam didn't answer right away, Dean pressed the blade in harder, causing y/n to grunt in pain. "You got it?!"
"Yeah, I... I got it", Sam croaked, his throat thick with emotion. Dean smiled at his brother, pulled the blade out of her skin, and laid it on the floor next to her head.
"OK, spread your legs for me, baby", Dean whispered. Y/n stared up at him with wide, terrified eyes, shaking her head frantically. Dean grabbed her by the throat and squeeze as he leaned over her face. "I said SPREAD. YOUR. FUCKING. LEGS. BITCH!" Y/n began to sob again as her trembling legs slowly opened. Dean slid back until his hips sank between her thighs.
"CASTIEL! PLEASE HELP ME!", y/n screamed in desperation. Dean let out a laugh and she looked up at him in shocked confusion.
"Hey Sammy! Why don't you remind y/n why calling Cas wont work!"
"No... no wings", Sam whispered in despair, a single tear rolling down his cheek.
"DING! DING! DING! DING! WE HAVE A WINNER!", Dean called out with a wide grin. "NO WINGS!" Dean's smile morphed into an obviously fake pout and y/n let out another broken sob. "By the time he gets here, it'll all be over." Dean stroked her hair almost lovingly as he whispered in her ear. He sat up on his knees and unbuckled his belt agonizingly slowly. "Did you sample the goods while I was away, Sammy?" Dean stared at his brother as he popped the button on his fly and pulled down his zipper.
"NO, DEAN!", Sam barked. "NEVER!"
"Never?", Dean remarked, raising an eyebrow. "That's not what it looked like when I walked in."
"That... that was a-an accident." Dean let out a loud belly laugh, pulling his jeans down passed his hips.
"An accident?!" He laughed harder, wiping the tears away with his thumb. "Oops! Sorry, y/n! I tripped and shoved my tongue down your throat! My bad!" Sam flinched and looked way again. But this time it was in shame. He knew what he did was no accident. "Come on, Sammy! Admit it! You want her!" Sam jaw twitched as he raised his head to glare at his brother. "Out with it Sam! You don't want me to start poking holes again, do you?"
"Y-yes", Sam growled angrily.
"Yes, what?", Dean breathed, caressing her nipple with his thumb.
"Yes, I... I want her." Dean snickered, grabbing the back of one of y/n's knees, pulling it up.
"That's too bad, Sammy. Because she's MINE!" Dean thrust into her violently as he shouted the last word. He slammed into her cervix and y/n screamed in pain. Sam screamed out his rage and pain with her. Dean groaned, burying his face in her hair.
