Chapter 5

They landed in a flurry of wings and splaying limbs in a field somewhere across the state. Castiel had tried to fight off his sudden attacker as they flew, causing them to land less than gracefully. He picked himself up and prepared to fight, only to see Lucifer standing in front of him, looking rather shaken.

"What happened?" Castiel asked, confused and slightly breathless.

"Why were you standing so close?" Lucifer demanded, "I told you after you came to me with the blood not to stand to close after you boned him."

"Where are we? Where's Dean?" Castiel pressed his own questions instead.

"That bone has one mother of a kick, Castiel! It's a God weapon, you should know that!" Lucifer brushed himself off. His eyes were unusually concerned.

"Kick," Castiel muttered to himself before puzzling it through, "Where's Dean? What's happened to him?" Lucifer didn't answer, just stepped towards the younger and comfortingly took his fists, still balled and ready to fight. Castiel just tensed even more. "Lucifer, where's Dean?"

"Where do you think?" was the only response he received.

Castiel's eyes widened in horror. "Purgatory?" Again, the Devil said nothing. His jaw slacking, Castiel bowed his head as he tried to make sense of the situation. "Why – why didn't you save him, too?"

"I only had time to grab one of you," Lucifer answered, voice barely more than a whisper.

"Bullshit!" Castiel cursed, violently tugging himself away from his brother, "You knew that bone had a kick! You knew where it would send us! You warned me but knew I had forgotten! And you're inside my head, always! I can feel you! You saw that Dean was standing too close, too, but you only grabbed me!" He blocked his brother's arms, trying to reach out to him, and took a swing at his face instead. Lucifer ducked his jab, and continued only to dodge, not fight back, as Castiel attacked him. Growing more and more enraged, Castiel summoned his angel blade to his hand and kicked the Devil to the ground. Lucifer grabbed his wrist as it came down above his head, preventing the younger from stabbing him in the throat but not attempting to throw him off.

"Castiel, just listen," he tried to reason.

"Was this your intent all along?" Castiel growled, "Get me to trust and welcome you again so you could remove my human friends from the picture? Sentence them to God-knows-what kind of fate in Purgatory since Hell couldn't hold either of them? So help me if Sam was taken in that blast wave too –"

"Sam is fine," Lucifer assured him.

"Right, I forgot," Castiel sneered, "you would never harm your vessel, not really. But Dean's just another human scum. It doesn't matter what he's accomplished or what he means to me. Just as long as he's out of your way –"

"Castiel," Lucifer pleaded, "I didn't know, honestly. You had asked that I leave you alone so I was. I want you to trust me. I peeked for a moment just to make sure everything was going okay. When I checked he was already set to blow. I had maybe a second. That's not even enough time for an angel to retrieve two people, and you know it." He reached up to cup his brother's face with his free hand. "I'm so sorry, Castiel. But I couldn't let you go to that place. An angel can't survive Purgatory."

Castiel fought harder to plunge the blade in to the Morningstar's throat, fighting back tears and choking down his sobs. If an angel couldn't survive, a human was hopeless. It was his fault. He should have told Dean. Even if he wasn't going to listen to his brother he should have at least passed on the warning. Lucifer should have grabbed Dean instead; if either of them deserved punishment, it was him, not the Winchester. The human had not devastated thousands to settle petty vendettas, had not smote half of Heaven because of an identity crisis. Dean had only strived to save as many as possible from the nightmares of their world. Castiel was guilty.

The Morningstar only stroked his face soothingly, his touch impossibly soft and his body relaxed trapped beneath the younger, with the exception of the arm that strained to keep Castiel from killing him. Each time he attempted to move Castiel's free hand shocked him with a painful burst of rage-fueled electricity, so he stayed where he was, continuing to stroke his brother's face supportively as he fought the tears that threatened to shatter his composure.

"Bring him back," Castiel finally commanded in a venomous growl that gave the elder chills.

"I can't," the devil whispered apologetically, "It's Purgatory, Castiel. Even I don't have access to that place."

"There are rumors," Castiel hissed, "of gateways into Purgatory from Hell."

"Myth," Lucifer denied, "If any existed when I was first cast down I sealed them all. The things in Purgatory did not belong in Hell; too easy for them to leak in to the physical realm."

Seething, Castiel wrapped his fingers around the Devil's throat, knowing well that angels did not need to breathe. His nails dug in to the fragile skin until he felt blood tickling his fingertips. "Bring him back," he commanded again, becoming more and more desperate.

"There are other rumors," Lucifer wheezed, air not necessary for his survival but important for talking, "that God built in a safety after creating Man should one of them end up in that horrid place. He never wanted his favorite creation to be condemned to something like that. Hell, sure, but not Purgatory." He had to struggle for breath to continue as Castiel's grip tightened. "Supposedly, a human can escape through a portal that will open for them if it gets near enough to it." He locked eyes with his emotional brother. "He has a way out, Cas. And he's smart. He'll find it."

With one last painful squeeze, Castiel released his brother's throat, who kept his composure, and just waited with him some more while he struggled with his thoughts, not ceasing to stroke his cheek comfortingly. As Castiel's body began to slacken, the Morningstar lifted his neck and pulled his brother's face down to place a feather-light kiss on his lips. Castiel jerked away at the contact and shocked Lucifer again with enough voltage that a pained grunt slipped through his clenched teeth. Seizing his opportunity, Castiel wretched his right arm from the Devil's hold, coming close to snapping the bones, and struck him across the face. Lucifer wrapped his legs around his brother's then and, grabbing his brother's wrists, flipped them, placing himself on top of the younger angel so he could stop the fighting.

"Peace, Castiel!" Lucifer implored, pinning his wrists above his head and trapping his legs between his knees. "I don't want to hurt you, brother."

"Go ahead!" Castiel screamed, "Because I'm going to kill you! You son of a bitch!"

"I'm sorry about Dean," Lucifer dropped his voice again in an attempt to soothe the writhing mess below him, "but I would not fail one of my brothers. Not again."

"What could you possibly care for us," Castiel spat, "you rebelled, despite the pleas of Michael and Gabriel not to. You killed Gabriel when all he wanted was for the fighting to be over. You condemned my friend to hell and haven't even flinched at the thought because what is his kind to you but a pile of cockroaches. What could you really care for your brothers when you seem so calm in the face of those you have murdered?" His words stung worse than any poison.

"You're right," Lucifer conceded, "I killed Gabriel. And I hardly hesitated choosing you over Dean. But I haven't forgiven myself for killing my baby brother, and I feel awful for what saving you has done to someone so close to you." Holding both of Castiel's wrists with one hand, he used the other to hold his face still so he would look him in the eye. "I hate hurting my brothers, Castiel. And I especially hate seeing you in so much pain already."

He bent down further, releasing the younger's face to hold his wrists more securely, and planted another gentle kiss on his lips. Castiel did not fight as much this time; actually, his entire body went rigid at the contact, tensed but completely frozen. Unsure of what this meant, Lucifer initiated another, and felt his brother's lips part marginally. He opened his mouth to reseal the kiss, and relaxed in to his brother's form. Castiel made to move again, and Lucifer thought he had made a mistake, but instead of attempting to hurt him, he dropped the knife, took the Devil's cheeks in his hands, and pressed their mouths together with fervor. Sitting up a bit, Castiel closed any remaining space between their bodies, moving one hand to wrap around Lucifer's torso, fingers tightening around his shirt and catching some flesh. The hand still cupping his face slid upwards to entangle the digits in his hair. Lucifer accepted his desperation greedily.

Castiel was ravenous, his anger translating into a powerful, almost violent lust. The fingers in his hair tightened around one clump and tugged hard, a few strands coming loose. He didn't mind. He actually kind of enjoyed the slight stinging. Sitting back on his heels, he pulled Castiel in to his lap and guided his legs around his hips. A grin spread across his lips, his tongue slipping in to his brother's hungry mouth, as the younger angel locked his legs around the Devil and dug his heels in to the small of his back. He took fistfuls of Castiel's trench coat before jerking it down and off his body, following suit with his jacket. He was prepared to take his time with the buttons of his dress shirt, but Castiel growled and urged him on impatiently. A chuckle rumbling deep in his throat, he wasted no more time and ripped the shirt clean off, the buttons popping off and flying who cared where.

Castiel released his vice grip on the archangel's hair long enough to push his over shirt off his shoulders and pull the remaining one up over his head, tossing it in the most convenient direction before reclaiming his lips. Lucifer twisted the tie still hanging from Castiel's neck around his arm before giving it a good tug and pulling their chests together. Castiel was breathing heavily and clearly overwhelmed, but he was desperate for any sort of release. The Devil would show him the most satisfying form of relief their Father had ever made.

Falling forward onto his knees, the Morningstar lifted Castiel and laid him on the forest floor again, the soft grass caressing the overstimulated skin of his back when Lucifer's hands could no longer. He pulled Castiel's legs up so his back was angled up, his pelvis resting comfortably in the Devil's lap, legs still wrapped securely around his waist. He made quick work of his belt and pulled his slacks effortlessly off his legs, discarding the shoes and socks along with them in what was almost one swift motion. His hands trailed over the impossibly smooth skin of Castiel's vessel, whose chest was rising and falling heavily in anticipation. He teased the angel's flesh for a bit longer before deciding that anymore foreplay would cause his brother to accidentally rip his meatsuit to shreds. His thumbs hooked in the band of the low-slung boxer-briefs and tugged them down, leaving the young, newly fallen angel completely exposed. Castiel reached up to him in silent pleading when he loomed over him again, willing away the rest of his clothing. His trembling hands found Lucifer's arm, supporting his weight, and the hand cupping his face again. Impossibly deep sapphire eyes glittered with lust and slight fear as Lucifer aligned himself with his brother's untouched entrance.

"I'll take care of you, Castiel," Lucifer whispered soothingly, gentle voice made of velvet as the hand supporting himself moved to quickly prepare and lubricate the area, slicking his own length just to be cautious. This was going to hurt, and in Castiel's completely short-circuited state of mind, he might not realize it until there's nothing but fire in wake of pleasure, so the Devil took the necessary precautions for him. Then he realigned himself and pushed past the ring of muscle.

Lucifer had forgotten what the pleasures of the flesh had felt like. Thinking human and demon below him, he had not succumbed to this primal act in a long, long time. Castiel was tight and warm and beautiful, so beautiful; his Grace, though fading, young and innocent and powerful and gloriously bright as it pulsated beneath his borrowed flesh. And the sounds that each thrust elicited from that desperate mouth… God, how he had missed his brothers. He leaned down further to place tantalizing kisses on Castiel's chest and abdomen, burying himself deeper in the younger angel writhing beneath him.

Castiel had learned human behavior quickly, and understood it fairly well, but sex was something he had never grasped. He had heard Dean talk of his sexual experiences, but did not understand. He had watched porn and been confused. Now, with the Devil deep inside him, filling him and causing this fire in his gut to be fueled while simultaneously extinguished, he understood their rabid desire for one another's bodies. His hands found Lucifer's back and they roamed wherever they pleased, nails digging harshly into his skin and leaving pale marks in their wake. He pushed back with every thrust, trying to get the Devil in as deep as was possible, to feel that painful bliss for as long as he could.

Lucifer shifted himself, angling himself slightly so he could tease more of Castiel's flesh, when he heard the most desperate cry erupt from Castiel's throat. It was pained, it was angry, it chilled him with its sorrow and aroused him with its desire for more. He guessed he had just hit the vessel's prostate, and attempted to find that spot again as a thin film of sweat began to claim Castiel's skin. The younger's moans became more pleading and whimpering as he surrendered all control and let his composure crumble to pieces, in such need of any sort of release the older could offer. "Lucifer," he pleaded in a barely-audible gasp.

The Devil grinned in a way only the devil could and increased the pace of his thrusts, finding the scene of debauchery in front of him that was once Heaven's most proud and devout soldier irresistible. He was surprised how quickly Castiel had managed to unravel him without even needing to try; he could feel his own ending rapidly approaching.

"Lucifer, I –" Castiel choked out, mind completely short-circuited and all sense completely lost.

The archangel said nothing, just took Castiel's length in hand and stroked it provokingly, trying to help him find that release he was so desperately searching for. Something seemed to be blocking the angel, keeping him dangling just over the edge without spilling over. The amount of tension and heart-wrenching emotion fueling his passion was also stopping him from finishing. Placing a kiss in the center of his sternum, Lucifer reached his Grace out to Castiel's.

The night became daylight in front of Lucifer's eyes. Castiel cried out as his Grace expanded to meet Lucifer's and then exploded in a burst of pure energy, fueled by the purity of the archangel's essence. Castiel didn't even notice the physical symptoms of his orgasm, only the euphoria of his Grace coming back to life from the smallest contact with Lucifer's own.

Lucifer came undone at the feeling and sight of Castiel's Grace, so raw from attention and reconnection with one of his brothers. He found his release deep inside Castiel, still struck with awe at the glory and beauty of another angel's Grace.

Castiel fell slack beneath his older brother, who panted for a minute, head resting on the younger's stomach, still buried in his body. Taking a moment to gain his composure, he pulled out, cleaned the both of them off, and returned his boxers and pants to his person, leaving his shirt off. He loomed over his overwhelmed brother, who lay frozen on the ground, eyes filled with relief and horror. The Devil placed a soft, reassuring kiss on the frightened one's lips, still swollen from their lustful kissing.

"Are you okay, young one?" he asked.

Castiel nodded slowly, not making any other movements, not even breathing, just compartmentalizing everything he had just done. He felt better, so much better, but the act was unspeakable, condemnable for an angel of Heaven. And he still considered himself a servant of the Lord. He had succumbed to the temptations of the flesh, and he had liked it. What was worse, he couldn't bring himself to regret it. His love for their fallen brother had never faded, nor his admiration. Lucifer loved him when the rest of their brothers and sisters had abandoned him.

"Yes," Castiel finally said, and sat up. The Devil leaned back on his heels to allow the movement. The younger brought their lips together once more, softly, lovingly, before restoring his own clothing and standing up, smoothing out his tie, still unknowingly on backwards.

"Where are you going?" Lucifer asked, concerned that he was lying.

"To find a way to get Dean out of Purgatory," he answered with that familiar determination Lucifer recognized in every one of Heaven's soldiers, and his younger brother was gone. Lucifer made no attempts to follow him. Castiel would not accept his help until he forgave him, and despite the release he had just experienced at Lucifer's hand, forgiveness was still a ways away. So he would leave the younger be until he calmed down. He only hoped that wouldn't take too long.

Lucifer looked around the forest he stood in. A slow grin spread across his face the more he noticed the effects of Castiel's Grace. Every dead leaf, every fallen twig, every dead or impure thing in the forest had been cleared away. Even his vessel felt a little better. He examined his skin, and felt his face; the Grace had repaired his vessel, who still continued to wear thin.

Yes, Castiel was beautiful. And he would see that beauty again.

Please leave any comments/constructive criticism. A simple "hey nice job" can go a long way. Please especially leave me any advice on the sex scene as it was the first one I have ever written and I'm an asexual 17 year old virgin so I hope it was satisfactory as far as smut goes. Thanks so much for reading!
