My birthday gift to you guys for not being updating my stories that often ^_^

Sam didn't tell Percy anything about Dean turning into a demon, knowing how close he was to their older brother so as far as Percy knew, Dean was dead.

So it was kinda a shock to the alpha wolf when he woke up, not being able to breathe with a weight on his chest and a pressure against his throat. He gasped for breath as he opened his eyes to see Dean on top of him with black eyes in full swing. "It's a shame that Sammy left you here all alone with me." His older brother chuckled, Percy was in too much shock to even move. I'm gonna die at the hands of my demon brother. He thought as his vision blur and he continued to gasp for breath.

Dean let up on his throat when he didn't fight back, letting him breathe harshly and his healing working on healing his crushed windpipe. The bruises on his neck wouldn't heal though, his healing was always messed up when it came to demons. He coughed slightly as he swallowed hard, looking up at Dean before his hand shot up to curl around the wrist that was about to bring down a hammer.

Percy bucked up, flipping them over and bending Dean's wrist at an angle that made him let go of the hammer. The wolf panted softly as he straddled his demon brother's hips, digging his left knee into Dean's right shoulder, pinning his left hand down to the bed. He was so going to kill Sam for not telling him about Dean later but now he had to focus on not getting killed.

Hearing a laugh from under him, he looked down confused. "W-What?" He asked, his voice cracking slightly since his throat was still healing. "This is going to be fun." Was the answer he got before he felt a force hit him in the chest, flipping him off of Dean and on to the bed next to him. He felt lips hit the bruises on his throat, causing him to hiss and moan at the same time. He didn't know if he should push Dean away or bring him closer so he just settled for laying on the bed and not fighting whatever Dean was going to do.

He groaned as he felt Dean sucking a mark on his skin before tilting his head to the side for him, breathing still heavy since his throat was still healing. Since he only slept in sweat pants, Dean didn't have to worry about taking off his clothes, though he heard a movement and looked up to see his older brother taking off his shirts and his belt from his pants.

Swallowing hard again, Percy licked his lips before gripping on to the bed sheets, trying not to feel guilty for letting Dean do this in his darker state, it wasn't like he could stop him anyways. Damn it, he was so going to hell for this, Crowley would be overjoyed about this. He wouldn't even admit that he thought about Dean that way even though he did. He lifted his hips so Dean could pull off his boxers and sweat pants before shifting around nervously on the bed, tensing as he felt him kiss him before relaxing and kissing his older brother back, yeah he was so going to hell for this.

He groaned as he felt Dean start grinding against him and couldn't resist the urge to grind back up against the demon that was now his brother. He opened his mouth into the kiss when he felt a tongue against his bottom lip, pushing his tongue against Dean's as he arched into the warm body above him. Feeling a lube up finger press against his hole, he tensed wondering when Dean had lube up his fingers before gasping into his mouth as he felt him push two fingers inside of him in one go.

He hissed at the pain a bit, not a stranger of bottoming but it still hurt sometimes since his healing kicked in right after he was done having sex. He panted as he slowly got used it to the pleasure-pain feeling and pushed back against Dean's fingers. "Oh, look at you, so desperate for it, aren't you, Perce?" Dean asked, his voice a purr as he thrust his fingers into him hard, hitting his prostate and making him see stars. He moaned loudly in surprise and arched off the bed.

He whimpered as Dean added a third finger before he continued to fuck himself on to them, gripping on to the sheets more, biting down on his lip to keep the noises inside and not let them out. He suddenly had a hand gripping on to his chin, forcing him to look up at Dean's face, "Don't you dare hide those noses from me." He ordered, glaring at Percy before dropping his chin and ripping his bottom lip out of his teeth, causing a cut to form.

Percy whined when he felt Dean remove his fingers before wrapping his legs around Dean's waist as he began to push into him, making him moan softly. His hands were pinned down above his head by on of Dean's hands before his hips got the same treatment. He about screamed when Dean pulled all the way out and slammed back into him, causing him to arch off the bed. His eyes flashed bright red and he groaned as he tried moving with his brother, his cock already leaking precum.

He wouldn't last long at all since Dean aimed for his prostate with every thrust, watching him turn into a begging mess under him, begging him to go harder, faster. His voice started cracking half way through since his throat wasn't all the way healed yet. His throat was grabbed again, making him gasp and moan as he felt Dean's fingers dig into his skin. The pressure wasn't as bad as when he first woke up so it turned him on more then anything else.

"Look at the big bad alpha submitting to a demon, his brother no less." Dean smirked as he jerked his hips, grunting in his own pleasure. Percy tried not to let his words get to him because this wasn't Dean, it was the demon in his body controlling him. He tugged at his hands and lifted his hips before flipping them over again so he was on top, moaning loudly when the change of angle caused Dean to go in deeper.

He rested his hands on Dean's chest and started riding him like a pro, which he kinda was since he bottomed most of the time when he had sex. He heard Dean's moans from under him and felt a bruising grip on his hips as he got closer and closer to his orgasm. He whimpered a warning before Dean sat up and kissed him hard. Percy returned the kiss, panting as he got a mouth full of tongue before feeling a hand wrap around his cock and jerking him off as he continued to bounce up and down on Dean's cock.

He moaned Dean's name as he came between them, clenching around Dean before feeling him cum inside of him. He breathed out harshly and went to pull away from Dean but his arms trapped him against his body, feeling lips against his shoulder in a surprisingly gentle kiss. He was confused for a moment before gasping as he felt a pain in the middle of his back, feeling Dean cut something into his skin. He sighed in relief once he was done before he was pushed off of his brother.

He watched lazily as Dean got dress after cleaning up his chest with one of Percy's dirty shirts on the floor. "Well, this has been fun but I gotta get back in the room before Sammy comes back." He said before kissing Percy harshly and then he was gone. Percy frowned, wondering if this was just a dream before he fell back to sleep. When he woke up again naked on his bed and sore, he knew it wasn't a dream and was hit with guilt.
