Underneath Your Skin

Chapter One

Dean still couldn't believe his luck. How did every good thing in his life always go sideways?

Dean grabbed the whole pie tin out of the big metal beast of a fridge and padded across the bunker to the long wooden table to indulge himself.

Screw health, I won't live long enough for it to matter, he thought bitterly shoving the spoon into the center of the store bought pie. He brought the cherry filled deliciousness to his mouth ready to forget about everything, at least for a couple of minutes, and just focus on the comforting taste of his most treasured dessert. But no sooner had the spoon touched his lips, when both the spoon and the tin disappeared from his grasp.

Dean turned around in surprise to see Cas in his dirty trench coat leaning against the wall.

"Dean, I know how you love your pie, but shouldn't you try to stay in shape?" Cas questioned in his deep gravely voice.

Dean stood, "Cas? Cas, what are you...." he trailed off remembering that behind that face was not his angel, but something else entirely.

Deans gaze darkened. "What are you doing here?" Dean finished sharply, untucking his gun from his waistband. He knew the move was pointless, but he felt better with the familiar, cold metal between his hands. "I will kill you, you son of a bitch. Answer me!" Dean growled.

Lucifer stepped forward. "Oh quit with the dramatics dean, we both know you couldn't nor wouldn't hurt me, not in this sweet getup."He said gesturing down the length of "his" body with a smile. You know, I miss having a vessel with the ability to contain me. Though I will admit your angel here isn't as fun to mess with as your brother.Too serious for my taste." He said casting a sideways glance at Dean seeing if he would react.

Dean didn't budge

Lucifer raised his eyebrows. "Though your angel here has some very interesting secrets up here that i'm sure he wouldn't want getting out." He said tapping the side of his head. "But I might be willing to share a few with you..."

Dean had to admit he was curious, but he wasn't about to give in that easily. "I don't give a fuck what Cas is thinking, I want you to get out of my house before I stop caring what body you're in." Dean growled his grip tightening on the gun.

"You know what? I don't think I like your tone." Lucifer remarked and suddenly he was across the room pinning Dean to the wall. "If you want my help you are going to have to help me first."

"And why the hell would I want anything to do with you?" Dean spat.

"Because I just so happen to inhabit your dear friends body" Lucifer said leaning down to his ear, he could feel the hot breath on the back of his neck stirring his hair. "And we both know that you would never let anything happen to your angel, would you?"

Dean could feel every inch of Cas' body pressed up against him and he hated the fact that even though this wasn't Cas, It still aroused him.

Lucifer leaned down closer and flicked his tongue up behind Deans ear, which felt like fire licking up the side of his face. Dean tried to shove him off but Lucifer had him pinned.

"What the fuck?Get the hell off of me!" Dean protested wrestling against Lucifers grasp.

"Oh Dean, watch yourself. You might hurt poor Cas' feelings!" Lucifer responded in a fake concerned tone. "You wouldn't want to do that now would you?"

"Well excuse me for not wanting the fucking devil literally breathing down my damn neck!" Dean responded hotly. "Now get the fuck off me before i shove my foot so far up your ass it comes out your mouth!" Dean said struggling against Lucifers grasp.

"Oh Dean, you make me all tingly inside." Lucifer remarked "Don't lie and say you are not enjoying this a little bit. I know someone else definitely is." He said wiggling his eyebrows.

Deans mouth fell open. "What?" He began but he didn't get the chance to finish the sentence because all the sudden Cas's mouth was on his, taking advantage of deans shock to shove his tongue down Deans throat.

He felt a rumble as Lucifer took pleasure in Deans anguish. Dean tried in vain to shove Lucifer off but it just made his grip even tighter. Cas' tongue swirled hot around deans mouth, his hands palming the front of deans jeans, doing unmentionable things to his body and making his knees weak.

Dean curled one arm up behind Cas' neck and grabbed a handful of hair. The other hand snaking around to his back pulling Cas in hungrily. God how he had missed Cas, though for some reason he couldn't remember why, or ever feeling this need before. He just knew that he needed Cas and he needed him now!

He shoved Cas off him then turned around and pinned him up against the wall with his hips, making quick circular motions soothing the growing erection in Deans pants. Cas let out a low groan that reverberated to Deans very core. Oh Fuck! He was done for. Dean grabbed a handful of Cas' hair and yanked his head back so he could fully get at Cas' neck. He first nipped at his ear then made his way down his neck, sucking and biting until he made it to the collar of his button up shirt.

"D..d...Dean?" Cas gasped

"Yeah, fuck! I'm here." Dean began to grind harder. He didn't know how much longer he was going to last. "Get these fucking clothes off now!" Dean demanded trying to yank Cas' coat off his shoulders.

"Dean!" Cas's voice shook him out of his stupor. "Dean?What? What are you doing?!"

"Cas?What the hell...?!" Dean stumbled away from him. "Cas?What just happened?! Did I just, did I just kiss..."

Cas's eyebrows furrowed. "Dean why were you kissing Lucifer? Why would you do that? ....How, how am I me again?"

"I, I don't know, he just, I don't know!" Dean said backing up and running his hands through his hair.

Suddenly Cas's face twisted in pain and he let out a grunt of effort stumbling backwards.

"Cas? Cas!" Dean panicked reaching for him.

Cas let out a sigh. "Well I definitely didn't expect that! Wow Dean! I should visit you more often. I knew we were going to have fun but I didn't think it was going to be this exciting!" Cas winked.

"Lucifer" Dean snarled and lunged at him. But with the flick of his wrist, Dean flew all the way across the room. Pieces of plaster rained down around him from the hole his body had made in the wall making him choke on the dust.

Dean staggered to his feet and wiped the blood off his mouth, the mouth that had just been entwined with lucifers...

He was going to kill this son of a bitch if it was the last thing he did. He didn't care if Lucifer was their only chance at defeating the darkness! Dean advanced again, angrier than before, only to have the breath knocked out of him by an unseen wave of energy.

"Dean, dean, dean." Lucifer said clucking his tongue, lazily walking towards him. "When are you ever going to learn? If you want more, just ask!" Lucifer chuckled.

"Now that we have had our fun, we have some business that needs discussing." He continued.

"I am going to reach down your throat and pull your intestines up through your..." Dean started choking up blood, spitting it on the floor, but it just kept coming. He fell to his knees gasping, scratching at his throat trying to get oxygen.

"There, now can we have a civilized conversation?" Lucifer asked in exasperation. "As I was saying, even I can't be everywhere at once and so while I am trying to find a solution to your little darkness problem, as I so kindly promised. You and Sammy boy are going to go find Crowley for me." Lucifer said smiling the smile of a man who thought he had won. "Because if not, as much as I would hate having to go through the trouble of finding a new vessel, I will destroy this one in a heartbeat." Lucifer smiled. "Got it? Good." Then he was gone.
