A/N: Another unbeta’d fic to finish off my kink bingo board! I’ve officially written them all! Wahoooooo 🎉

The sight of the angel by the stream is euphoric. Thrilling, incandescent. Dean doesn’t know when he turned into such a fucking pussy but seeing Castiel again feels like being whole. Cas has been an extension of him since he put that goddamn brand on his shoulder four years ago. And even though the scar isn’t there any longer, Cas had marked Dean in other ways. Deep, invisible ways Dean never intended to admit to, but recognises in himself now, with Cas standing stoically and bedraggled by the water’s edge. 

“Cas!” Dean laughs as he pulls him into a hug, one the angel doesn’t return. “Damn, it’s good to see you.” He makes himself let go and pulls back to look at Cas more closely. “Nice peach fuzz,” he pokes at Cas’s unkempt beard, raising his hand as if to run his fingers across it, but then remembers Benny and lets his hand drop. There was a lot that had gotten complicated since they’d been separated in this hellhole. 

“Thank you,” Cas responds in his grumbly timbre, and Dean can’t help the smile that comes to his face at finally hearing his voice again after so long. And to hear him speaking sanely again, back to his old grumpy, wooden self. Dean’s missed this Cas. Now they can finally get out of this god forsaken cesspit of crazy and creepy. 

Except Cas doesn’t want to go. 

“Cas, buddy, I need you,” Dean admits with a breathless laugh, the closest he’s ever come to saying what he really wants to say. Cas’s expression drops, forlorn in his convictions. 

“Dean,” Cas shakes his head, but Dean doesn’t let him finish. 

“And if Leviathan wanna take a shot at our ass, let ‘em. We ganked those bitches once before, we can do it again.” 

“It’s too dangerous,” Cas protests. 

“Let me bottom line it for ya. I’m not leaving here without you, understand?” Dean isn’t taking no for an answer goddammit, not after how long it took to find him, not after everything else. Cas pauses, takes a deep breath, considering. 

“I understand,” he nods gravely, and Dean breathes a sigh of relief, pulling him in for another hug. He hears Benny scoff behind them but decides he doesn’t care enough to break away. Cas tucks his head against Dean’s shoulder, his new beard scraping roughly against his neck. Dean shivers in his grip, but reprimands himself. Now isn’t the time. 

As if Castiel had read his mind, and it isn’t the first time Dean’s wondered if Cas can do that, Cas pulls out of the hug and kisses him. He grunts in surprise against the angel’s lips, greeted with an onslaught of tongue and fervour reminiscent of what Dean could recall of Cas kissing Meg against the wall of that grimy warehouse. Dean remembers feeling incredibly conflicted about that, simultaneously jealous and turned on. Experiencing it put him on a whole new plane. For an angel who was still a fucking virgin so far as Dean was aware, the guy knew what he was doing in the tongue department. He could hear Benny trying to talk to them but his mind was far too distracted to discern any of the words. 

Suddenly Cas pulls back and Dean is left staggering, staring blindly at the angel, who is panting hard and staring back at him. 

“You two done yet?” Benny grunts, arms crossed over his chest, clearly unimpressed, and if Dean’s reading it right, just a touch jealous. He’s flattered, really, that he’s so desirable. Dean grins sheepishly at the vampire, with a shrug of his shoulders as if to say ‘well, can you blame us?’, and Benny rolls his eyes back. 

“No,” Cas grunts, and both Dean and Benny turn to him. It takes Dean a moment to realise that Cas was answering Benny’s question. “No we’re not done yet.” 

The breath is knocked clean out of him as Cas pulls Dean down to his knees and shoves him roughly back onto the bank of the stream, climbing over him and kissing him again, fierce as ever. 

“Jesus Christ,” Dean hears Benny groan somewhere behind them. “Come find me when y’er done.” 

Dean tries to grunt out an agreement but it turns into a moan as Cas’s fingers fumble down his chest and land on his jeans. Cas isn’t careful with the clothing, and Dean’s not inclined to care about that right now, though he may regret it later. He reaches down to get Cas stripped out of his garments too. The trench coat comes in handy as a blanket to lay down so he doesn’t get mud up his ass. 

It’s rough; messy. Just like everything else in Purgatory. Dean is wide open, vulnerable as he’ll ever be, but even in a place like this, he still feels safe. This feels right. 

The pain of Cas pushing in is dulled by the pleasure of the angel’s hand on his cock, pumping him roughly in his spit-soaked palm. Dean’s eyes squeeze shut against the onslaught of sensations, too overwhelming, and he lets himself go, losing himself to just another primal urge that seems to be all he can cling to in this place. 

“Fuck, this was worth it,” Cas grunts above him, and Dean groans in agreement. This was absolutely worth the wait; Cas filling him up, finally being inside of him, not just near, not just touching, not just scarring, but actually inside. Part of him. 

“God, Dean,” Cas groans, thrusting harder, hand dropping from Dean’s cock as he chases his own pleasure, arms dropping to either side of Dean’s head as he falls forward. He fucks into him without mercy, Dean’s hips banging into the ground with every push, and even though Cas isn’t jerking him off anymore, this new angle is getting something inside him that’s pushing him over the edge. 

“Shit, Cas!” Dean moans, punching his hips back, trying to force the angel back inside him. “Fuck, gonna cum.” 
“Almost,” Cas hisses through gritted teeth, breath hot and sharp against Dean’s ear. Then in a blinding rush of heat and pain, everything is over.

Cas straightens up, pulling out of Dean’s body with a relieved sigh. He cracks his neck, shrugging away the tension and ache in his muscles. He’ll be refreshed soon enough. Dropping the obsidian blade back to the ground he stretches his mouth wide and roars as his teeth sink into his prey, devouring from the head down. 

Other Leviathan frowned on it, but he always thought it was more fun to play with your food first.
