Castiel walked into Dean's room to find him asleep on the bed with his Beats Headphones on, his right arm stuffed behind his head as his left arm draped across his abdomen. Music was humming loudly though the headphones; he was listening to "Love Songs Drug Songs" by X Ambassadors. Weeks had passed since that night, he could still fell Dean's lips on his neck. He couldn't get his words out of his head, "it's not wrong." It was driving him insane; making him question everything he knew. It wasn't common for an angel and a human to fall in love, but possible, but an angel and a demon? That's impossible, right? He knew he felt a strange emotion towards Dean Winchester, and even now that he was a demon he still felt it. He watch the hunter stir in his sleep "Was he having a nightmare?" he whispered bluntly as he placed two fingers on Dean's forehead and was pulled into his dream.
Dean was tied to a chair in the middle of the dungeon in the bunker; a massive Devil's Trap was drawn under him. His mouth was ducted taped and his hands were held together with demonic handcuffs. He held his head low until he heard someone enter the dungeon, his eyes narrowed and blinked black as Castiel entered from the doorway. It was bizarre for Castiel to see a version of himself in someone else's dream. Dean's interruption of Castiel was spot on; it was like looking in a mirror. Yet, this Castiel seemed different, assertive; about what he did not know. This Castiel approached Dean silently, his expression firm. Once he reached the edge of the Devil's Trap he moved his hand swiftly in the air, causing some invisible force to rip the duct tape off Dean's lips. Dean's redden lips turned up into a demonic smirk as he looked into those blue eyes, his breathing getting heavier with each second they stared at each other. He pulled his blue tie undone, letting it drop to the floor as he stepped closer to Dean. He ran his fingers up the hunter's neck, then finally to the back of his head where he took a fist full of his hair and pulled, causing his head to fall back slightly. Dean bit his lower lip as he kept his eyes on the angel, the pain excited him. His cocked strain angrily against his jeans as the angel dipped his head into the nook of his neck, kissing lightly as he made his way to Dean's jaw line and stopped. He moved his lips to Dean's ear; "Well this is going to be so much fun." He whispered, laughing like he did when he was possessed by Leviathan. He snapped his fingers and the next thing Castiel knew they were in Dean's room. Dean was lying on his back with his hands chained to the bed board and the angel was standing at the end of the bed, smiling demonically as he removed his coat, dropping it to the floor. He swiftly moves his hand again causing the buttons on Dean's shirt to fling across the room, exposing the hunter's muscular chest. His smile grew as he moved his hand quickly down causing Dean's jeans' button to fly off. "Cas…" Dean whimpered, arching his back and tugging hard against his chains. Castiel bit his lip as he watched Dean's interpretation of him tease Dean. He could feel a blush creeping on his face as he heard Dean call out his name. "What is happening to me?" he thought to himself as he felt how excited he was getting. Dean's Castiel removed his black blazer and started unbuttoning his shirt slowly, watching Dean eye his fingers. The shirt felled off his left shoulder; exposing his chest to the hunter. He moved his hand again causing the chains on Dean's hands to become slack, he smirk as he gestured Dean to sit up and come to him. Once Dean made his way to the end of the bed, the angel started unbuckling his belt, dropping his slacks to the floor, exposing his hard throbbing cock. Dean sat at the end of the bed in front of him; looking up at him and smirked. He ran his hand on the angel's thigh, causing him to close his eyes at the touch. He placed his right hand on the back of Dean's neck, pulling his head close to him. Dean licked his lips as he took him in his month, slowly bobbing his head back and forth. A moan escaped from Castiel's lips at as he watched Dean's Castiel lean his head back as he pushed Dean's head closer to him, making the hunter take him deeper. Castiel was taken aback when he realized how much his breathing had quickened and how hot his face got. He felt his own cock strain against his slacks. "This dream is a den of iniquity…" He whispered as he suddenly felt wrong watching Dean's fantasy. A part of him wanted to leave and forget what he observed here, but another part of him wanted to stay and let Dean's fantasy run wild, even replacing the dream Castiel with himself. "Fuck Cas…!" Dean's moan snapped Castiel out of his thoughts; Dean's Castiel was now thrusting himself slowly inside Dean, stroking the hunter's cock to match his movements. The angel leaned down to claim the hunter's lips while increasing his pace. "Hold. Up. Let. Me. Catch. My. B-breath." Dean panted out in-between kisses. "Not a chance…" He panted against his ear, a smile in his voice. He gripped Dean's hip and pushed himself deeper inside of him, hitting his prostate. "C-Cas!" Dean moaned out as he felt himself getting closer to the edge, grabbing the back of the angel's thigh; urging him to go faster. "Damnit Dean..." he growled as he bit the nook of Dean's neck and thrust in harder. "Fuck!" Dean managed to moan out as his orgasm washed over him. Castiel was taken aback from a strange force that injected him out of Dean's mind. He found himself sitting on the left side of the bed in Dean's room. He was confused, he looked around but there was no other Castiel it was just Dean laying on his bed with his headphones on. He looked over the hunter, he had a bead of sweat across his forehead and his jeans were darker in the crotch region. Castiel's adverted his gazed as he noticed him stirring awake, the hunter rubbed his eyes trying to clear his vision until he felt another present in his room. "Cas?" Dean looked as confused as him. "Hello Dean." He answered as he looked back at Dean. "What were you dreaming about?" Dean's face became hot and noticed the only cold spot on his body, his eyes widen, face turning four shades of red. He jumped out of bed, quickly making his way to the bathroom, "Cas, we talked about this, it's just creepy!" He growled as he slammed the door. "Fuck! Did I really just have a wet dream!? What am I fourteen?! Oh GOD was Cas there when I came?!" He whispered to himself as he got himself a clean pair of jeans. "Maybe he's too oblivious that he didn't think anything of it". He assumed as he ran his hand though his hair, opening the door to nobody. His room was empty; he must have scared off the angel.
"Cas?" Dean called out as he made his way to down the halls. He moved his head left and right peeking into empty rooms, no sign of him. Once he made his way to the library he found Sam reading up on the case they were working on, he had his laptop in front of him and random papers scatter around the table. "Sammy, have you seen Cas?" he asked as he made his way to grab Sam's beer for himself. Sam of course snatched it in time. "No, why? Did you do something lewd towards him again?" Making his normal bitch face at Dean whenever he was up to no good. "I didn't do anything lewd to his face." Dean smirked while those words rolled off his tongue seductively. Sam rolled his eyes and took a sip of his beer. "Dean, have you taken your dose today?" he asked while narrowing his eyes at him. Dean's smirk faded as he rolled his eyes "I'll be back." He made his way back to his room, as he open the door he saw him, the angel, looking at the blood filled syringes. "Is it painful?" Castiel asked, not bothering to turn around to see if he was even there. Dean made his way next to him. "It hurts like hell" He admitted as he took one of the syringes from the bag in the angel's hands. He stared at it hatefully; he didn't like injecting himself, it made him feel exposed, weak and it also made him express things. He wasn't sure if he was ready for Castiel to see that side of him, but a part of him wanted him to see. He stepped closer to Castiel as he rolled up his sleeve; injecting the long needle in his forearm, knowing damn well what was about to come next. Dean's legs buckle under the extreme pain shooting though his body; he reached out and grabbed the angel to steady himself. His breathing became ragged; he started to panic and his grip on Castiel became tighter. "I'm the devil's son straight out of hell Cas, and you, you're an angel with a haunted heart." He pulled away from him to stare at those blue eyes, narrowing his black eyes. Castiel had fear and confusion in his eyes, and he didn't like the statement about him having a haunted heart even if it's 100% true, it scared him. "If you're smart you'd run and protect yourself." He growled as his grip became tighter, closing his eyes tightly, trying to fight off the pain. "There's nothing to be gained Cas, because I can never change and you can never understand my sickness." He pulled him hard against him, claiming his lips, kissing him hungrily. Castiel's eyes widen at the sudden contact. The kiss was rough and raw; Dean licked and nipped at his lower lip until the angel could no longer hold back a moan. He seized the opportunity and claimed the inside of his month, exploring this holy place with his tongue. He placed his hand on the back of the Castiel's neck, Deeping the kiss, trying to show him a heart full of pain and desire he had inside him. Castiel place his hands on Dean's biceps, he thought he was going to push away again like the last time, but he didn't instead he pulled him closer to him. Dean walked him backwards until his legs hit the bed; knocking both of them on the bed, keeping the kiss intact. Castiel ran his hands though Dean's hair as their tongues fought for dominance. Dean broke the kiss; panting, looking into Castiel's eyes. "You're the perfect drug when it hurts like hell, Cas…" He reached for Castiel's hand and placed it on his shoulder with the handprint scar. "I've never needed anyone so much," his eyes were filled with a mix of sadness and desire. "I've loved no-one else besides Sam for as long as I can remember, until I met you Castiel," He placed his hand on his cheek; slowly rubbing his thumb over the angel's redden lips. "I curse myself...you're a fucking angle and," He almost choked on the words as he averted his gaze from the angel's, he couldn't face him. He furrowed his brow, becoming irritated at the thought, what the hell did he do to deserve this, this tortured was worst then being on the racks in Hell. "Dean…" Castiel whisper as his grip on Dean's shoulder tighten. "I can never be human again Cas!" Dean growled as he yanked Castiel's hand away from him, giving himself some distance from the angel. Castiel sat up and watch as Dean made his way out of the room, slamming the door behind him. "Dean…"
