Part Three
Lips met with an angry clash of tongues and teeth, Castiel groaned helplessly into Dean’s mouth. Dean took him over completely and Castiel had no choice but to give into the sensual assault. “Why?” growled Dean between kisses. “Why?”

“This is the only way,” Castiel breathed, “to keep you with us.”

The air shimmered and left both of them naked. Dean chuckled. “Handy.”

Castiel gave him a brief smile. “For now.” Whatever else he had to say was swallowed by Dean’s kiss. Castiel kissed back, opening his mouth and -

And Sam sat up, waking Castiel.

“What’s wrong?” The Angel asked immediately.

“Yeah,” Sam murmured, thinking quickly. “Hey Cas,” he said, laying back down beside Cas. He glanced at the empty bed beside them. Dean hadn’t come back. “About Dean.”

He could feel Cas tense. “What about him?”

“I think... I think I know how to keep him,” Sam whispered.

Castiel turned in Sam’s embrace. “How?”

“You.”

The Angel blinked. “Me?”

Sam kissed him, gentle and light against his parted lips. “What about me?” Cas asked. With a look of fond amusement, Sam kissed him again, coaxing Castiel’s lips open with his tongue. “Sam What does kissing me have to do with De-,” he trailed off. “You wish for me to share my body with Dean?” He pulled away, looking troubled. “But what about you?”

“I’ll be fine,” Sam said quietly. “Dean doesn’t need me. He needs his Angel.”

Sam made to get out of the bed but Castiel held fast. “I will not have sex with Dean. Not without you.”

“Uh, you can’t possibly be suggesting that I sleep with my own brother?” Sam said.

“Wouldn’t doing anything with him without you be your idea of infidelity?” Cas asked. “I am with you.” Castiel looked uncertain and let go of Sam’s waist. “Aren’t I?”

Sam pulled him close, crushing Castiel to his chest in a fierce, protective hug. “Yeah. Yeah Cas. You’re with me.”

“Then what do we do about Dean?” Cas whispered into Sam’s chest.

“I guess we’re seducing him together,” Sam replied. “I’m already bound for Hell, right?”

Castiel kissed him instead of answering. He still had much to learn about humanity and the consequences of his slow destructive fall, but the speed with which his wings burned off was the least of his problems. He didn’t have much of a clue about where he was bound or what to do next.

His father never condemned anyone for loving.

No one except Lucifer.

They’d been brothers too.

“How are we going to work out the logistics, Sam?” Castiel asked, after a few minutes of silence in an effort to derail his train of thought.

“Hm?”

The response was fuzzy with interrupted sleep and Castiel felt a foreign emotion in his chest. “When we seduce Dean. You are clearly more skilled in the art of what we’re doing. How will it work with three?”

Sam turned his face into Cas’ neck and sighed. “Someone will have to be in the middle.” Cas could feel the small smile. “Probably you.”

Lust pooled low in his belly. Lust that was his, and not something he could feel muted through Jimmy Novak’s borrowed body. “Me? Why me?”

“It’s you he wants,” Sam reminded gently. “Cas... if you don’t want to do this...”

“I defected for Dean. I will not baulk at this.” Never mind that his defecting didn’t result in his slow crumbling fall.

Learning to love Azazel’s child had done that.

*

It was the slamming of the door that woke Sam and Castiel the second time, and they opened their eyes to a blazingly angry Dean. “So. The two of you share now?” he snapped.

Shaking off the last vestiges of true rest, Sam rolled his eyes. “We were saving the other bed for you, jerk.”

Dean’s eyes narrowed and there was no returned ‘bitch’ or anything that even looked normal in his face. “I think we should start getting two rooms now, what with your angel sex.”

It was scathing enough that Sam’s insides coiled and Castiel stiffened. “Dean, come on.”

“No, you come on ” He opened his mouth and Sam could see the chastisement and ensuing rant growing in Dean’s eyes. Then he couldn’t see anything at all, because suddenly Castiel was there, his mouth sealed over Dean’s.

Dean made a surprised noise that Cas swallowed, and Sam was shocked to discover how erotic it was to watch Cas completely dominate his brothers mouth. It didn’t look like Dean was kissing back but he wasn’t stopping the Angel’s efforts to coax a response out of him. Maybe the person in the middle was going to be Dean.

The idea terrified him and exhilarated him at the same time. He slipped off the bed and came up behind Cas, resting his hands against the angel wing marks. Castiel groaned against Dean’s mouth and he reflexively placed his hands on the Angel’s waist. Taking that as permission, Castiel pulled Dean closer.

They continued to kiss, and Sam began to brush his fingers over the wing marks. Cas’ hips flexed against Dean’s and Dean’s fingers clutched suddenly in Castiel’s t-shirt. The Angel tore his mouth from Dean’s to gasp out, “Sam, if you do that, this will be over very quickly.”

Sam grinned and laid a kiss on the side of Castiel’s neck. “Sorry.” He went back to rubbing lightly, with the palms of his hands. Castiel shivered pleasantly and re-caught Dean’s mouth with his. “Dean,” murmured Sam, “if you don’t want to keep going, just say so. We’ll forget this ever happened.”

That seemed to spur Dean into action. He left go of the shirt to cup Castiel’s face and honestly kissed him back, tilting their heads into a better position. Castiel moaned loudly into the kiss and pressed himself lengthwise against Dean.

For a split second, Sam felt a pang of...... something...... at the impassioned embrace. Until Cas clutched at his hand and tugged him closer. “Bed,” the Once-Angel gasped. “Bed now.”

Dean pulled away, looking nervous. “Cas...... I...”

But the Angel kissed him gently, halting his words. “No, Dean. I know no other way to show you how deep my devotion runs for you. Or how deep your brothers love for you is.” Dean’s jaw had softened and his entire body relaxed. “I may have already fallen Dean, so it means that I will be here to catch you.”

This time, Dean kissed him.

The two of them stumbled to the bed. Sam withdrew, letting Castiel’s fingers slip from his hand. He’d spent the entirety of his teenage years watching as women and men he’d had a vocal interest in turn to Dean instead. It stood to reason that Cas wasn’t much different.

Castiel’s hips were slowly rutting against Dean’s, and for his part, Dean seemed to pick up on the marks on Cas’ back. Dean was pulling the Angel’s shirt off to have better access to the broad, muscled plane of skin while Cas began tugging at Dean’s jeans. Sam fell back, lingering in the doorway of the bathroom, simply watching. It was a pretty picture.

His brother didn’t want him, but he clearly wanted Cas.

He was getting ready to leave when Cas stood, shucking off his jeans and dropping them by Dean’s. “I do not think so,” he growled, invading Sam’s space. “You belong in our bed.” He tugged Sam closer by his belt loops. “Share with me.”

He allowed himself to be led to the bed where Dean was watching with concerned wide eyes. Nerves were threatening to choke him, then Castiel kissed him. Just like the last several
times, the world melted away and Sam managed to forget about his staring brother. As they kissed, Cas began to unbutton the shirt he was wearing, sliding it over his shoulders to pool at his feet. When the shirt finally fell to the floor, Cas started onto the pants.

Then Cas jerked, moaning into the kiss and Sam’s eyes flew open and saw Dean scrape his fingers down Cas’ back. “Fuck,” Castiel grunted, jerking his hips into Sam’s.

“We need to get him to say that again,” Dean said with a filthy chuckle, his eyes on his brother.

And like that, the situation clicked, and Sam began to participate fully. He pulled the shirt the rest of the way off Castiel’s shoulders, and deepened their kiss. Together, the three of them shuffle-walked to the bed, Sam and Castiel still kissing. Once Cas’ knees hit the edge of the bed, Dean knelt behind him and lowered him down between the two brothers.

Sam pushed his knees apart as Dean cradled his upper body, gently rubbing the Marks. Sam looked up the lean line of Castiel’s body to meet his brothers eyes. There was a wealth of information there; nerves, confusion, desire, but below it all, a burning, kindling hope. Sam dipped his head and looking all the while into Dean’s green eyes, licked the entire length of Castiel’s cock.

The Angel shouted, arching his hips, straining against Dean’s grip. Sam held him down with an arm across his stomach, and Dean immobilized his hands.

He sucked only the tip into his mouth and rolled it around in his mouth with his tongue. Castiel gasped, shouting something in Enochian that neither brother could understand. “English, Cas,” Sam could hear Dean murmur.

Cas whimpered but didn’t speak again, too busy writhing against Sam as he slipped his lips slowly down the whole shaft. It had been a few years since he’d done this but he managed to bottom out after a few false starts. Brady had been an incredibly patient teacher.

He swallowed around Castiel’s length just as Dean bit down on his neck and scraped blunt nails over the raised wing marks. The Angel in question bucked and writhed, screaming. He started out in Enochian, but as the word flow progressed he began whispering, “Please, please, please, Sam please...”

Sam pulled off to Castiel’s moan of protest. “You want a turn?” he asked hoarsely of Dean.

The confusion had fled Dean’s eyes leaving them burning with unbridled lust. “He’ll recover,” he growled.

Swallowing hard, Sam dipped his head down again and began licking small concentric circles around the rigid length, using both hands to still Castiel’s hips. He groaned against the Angel’s dick when Dean shifted on the mattress and caused it to rub against Sam’s own unattended erection.

It was the groan that did it. Castiel blew apart beneath them, his intense orgasm taking all three of them by surprise. Sam’s name was torn from his lips and he arched up, nearly choking Sam. Sam kept up light suction until Castiel’s cock was soft and twitching. Only then did he pull off, cracking his jaw with a grin. “Did we break him?” He asked, slyly.

Castiel lay there panting, unmoving, his skin shivering with the aftershocks. “We must have,” Dean rumbled.

He began kissing the side of the Angel’s neck, soft, dry presses of his lips. His hands swept up and down, palming warmly over his erect nipples. Castiel twitched and opened his eyes.

“Your turn,” Sam murmured, levering himself painfully off his knees. Both cracked and Dean winced.

“Y’okay, baby brother?” he asked, shifting the dead weight of Castiel to lie flat on his back, still blissed out.

“Mm-hmm,” murmured Sam. “Just fine.” He slid up on the bed on Castiel’s other side.

He settled himself there, and was taken by surprise when Castiel pounced. The Angel rolled over onto Sam’s lap, resting on all fours to kiss him. Dean made a noise halfway between a sigh and a whimper as Castiel ground down on Sam’s dick.

“Pants,” Castiel groaned, “off ” With a shimmer, Sam’s jeans were halfway across the room and on the table with his laptop. Hot skin slid together and Sam bucked up, wrapping one leg around Cas’ waist.

His arms were trembling with effort, but Cas looked up and met Dean’s burning eyes. “Fuck me,” he said clearly.

Dean’s breath exploded out of him and Sam gasped, thrusting up against Cas. “You...?” Dean whispered and Cas nodded once. Sam could feel the angel’s cock fill up with blood again, trapped as it was between their bodies.

“Fuck me to keep you,” Cas whispered. “Please Dean.” His head dropped and Dean took no time to scramble around them on the bed, kneeling behind Castiel’s raised ass. “Fuck me.”

Sam leaned over the side of the bed and hunted through his duffle. There was lube in there somewhere. When he found it, he tossed it over to Dean who grunted in thanks. Dean grasped Castiel’s hips in an effort to stop him from moving, and spread his legs obscenely.

The youngest brother shifted, raising his knees, and helping hold Castiel up. The Angel dropped to his elbows to kiss Sam as Dean stared reverently down at the two of them. Sam carded his fingers through Castiel’s messy hair, making it worse and disentangling the gel there, letting the curls fall loose.

Castiel brushed his nose against Sam’s cheek. “Remember,” he whispered in Sam’s ear, pressing a hot, opened mouth kiss against it before speaking again, “You are mine.”

Sam gasped and arched up, brushing their erect cocks together. “I remember,” he murmured.

Dean couldn’t hear what they were whispering together but Cas was beginning to shake, so he laid a gentle kiss on the Angel’s spine, right where it bowed down in a gentle curve. He shivered against Dean’s mouth, caught between arching up and arching down. Dean peppered kisses down his spine, finally ending just before the smooth skin of Castiel’s ass. The Angel froze, trembling finely.

He brushed his thumbs over the crack of his ass, slowly coaxing it open, caressing what he found there with his fingers. Castiel gasped and shuddered, resting his forehead on Sam’s chest. Dean kept it simple, stroking lightly before he laid his lips against the hole. Another stream of Enochian spilled out of him, and he bit down on Sam’s collarbone.

Sam gasped, clutching at Cas’ hips. “God, you can’t do that Cas.”

He was shaking, but managed a small, self-satisfied grin. “Do what?” he asked with a purr, “bite you?” Sam opened his mouth but Cas bit him again, as Dean slid one spit slicked finger inside of him. “Fuck ” he said again, and Sam grinned.

He was writhing against Sam with each twitch of Dean’s finger, and Sam shifted to align their cocks so they slid together slickly. “Dean,” Castiel said hoarsely. “I may be cut off from heaven, but I can promise you that you will not hurt me and if you don’t hurry up and fuck me I will not be accountable for my actions.”

Dean glanced over his shoulder at Sam. Sam shrugged, and Dean found the lube from where he left it. He squeezed a dollop into one hand and slicked another finger up, shivering. “Are you sure, Cas?”

“Will it keep you with us?” was the answer he got, and Dean paused long enough to make the Angel turn his head to look at him burningly over his shoulder.

“Yeah,” Dean whispered. “You can keep me.” He began working in another finger, to the sound of his Angel and his brother kissing. Dean kept getting distracted by them; maybe it was the way Sam’s larger hands cradled the back of Cas’ neck, as they kissed, or the way the Angel’s hips shifted with each time their mouths separated.

He added another finger, just in case, and Castiel cried out impatiently against Sam’s lips. Dean grinned to himself and curled all three fingers up and touched the small button he found here.

Castiel’s whole body seized as a burst of pure pleasure incinerated what was left of his reservations and his mind. “What was that?” he asked breathlessly a moment later.

“Prostate,” chorused the Winchesters, sharing a smile.

“Do it again,” Cas demanded, writhing up against Dean’s hand.

“Do you one better,” Dean promised and withdrew his fingers. Cas cried out again in protest and Sam caught his mouth with his, silencing any further words.

Dean snagged the lube again and coated himself even more liberally. “Ready, Cas?” he asked gently and slowly the Angel nodded against Sam’s chest.

Cas was jarred at Dean’s first slide into him. “Relax,” soothed Sam, rubbing up and down his back. He shifted once, then went boneless and with a shout of surprise, Dean slid home. They held their frozen tableau for a long, drawn-out moment, the room filling with their harsh breathing.

Then: “Dean, please. Move.”

That seemed to spur them all into motion. Sam spread his knees which cradled Cas between them; pressing them groin to groin. Dean began to piston his hips, fucking down into Castiel’s willing body. The Angel’s erect and neglected cock rubbed against Sam’s and Cas began moaning against Sam’s neck.

“Dean,” groaned Cas. “Please... I... please.”

Dean got the message.

He changed the angle of his thrusts, hitting Cas’ prostate with each bottom out. He reached around and grasped Castiel’s dick, catching Sam’s with it and jacking them together.

Sam’s eyes flew to his brothers. Dean’s face was set in intense concentration but when he felt Sam’s eyes on him, he looked up. His held a question, and Dean gave him an answer. “Yeah, Sammy,” Dean said. He meant ‘I love you’. He meant ‘I forgive you.’ He meant ‘Me too.’

And Sam came.

When Sam went, so did Cas, which set off Dean. It was over quickly and there was nothing glorious about it. Castiel collapsed on Sam and Dean managed to roll to the side.

In front of Dean’s eyes the black Marks, the wings he’d been slowly losing, burned completely away, leaving his skin clean and without blemish. “Cas...” whispered Dean.

The not-Angel shook his head where it rested against Sam’s neck. Sam rolled them to one side, sandwiching Cas. “I said I would give anything to keep you,” Castiel whispered brokenly. “So I did.”

Dean and Sam curled around him as he cried.

It had always been about Dean.
