"Lovely," Lucifer said, sounding wry and amused all at the same time. Sometimes Dean's language just threw him for a complete loop; it was like he had absolutely no filter at all. "But that's hardly a bad thing," he agreed, before taking Dean's hand and moving it away from his own erection. "No touching." A pause. "Castiel, you could go a little faster now."
Castiel was pretty sure that he was just completely wrecked again -- moving his mouth faster benefited him before it allowed him to rock back a little harder into Samandriel. He probably would have done it even if Lucifer hadn't asked. If he noted Dean's crude terminology he didn't let on to it, only basked warmly in the Enochian Samandriel was speaking and huffed sharp little breaths through his nose.
The little bit Dean had managed to touch was enough to draw him further from the edge that he could easily last a while longer. He was still resolutely refusing to beg, but because he really did love his husband, moaned freely for him. “You can do better than this, Lucifer,” he murmured. The other man knew the line of work he’d been in before, had to know that this was hardly a challenge for Dean.
Samandriel wasn’t sure how he felt about something that felt both so good and so wrong. Castiel was his superior. Everyone in the room was technically someone who outranked him even if Dean was only human. He was Michael’s vessel. By sheer potential alone, Dean’s orders were to be obeyed. The combination of tight and slick around him was proving to be more than Samandriel expected. He couldn’t help but go faster into him, a bit harder. “Do you like this?” he asked Castiel, switching back to English so the others could understand him.
"I'm not doing anything at all," Lucifer demurred in that tone that was somewhere between bored and patient all at the same time. "Only giving you time to enjoy yourself and taking our time. Would you like me to try harder?" He moved a little, turning enough to kiss Dean's shoulder before sinking his teeth sharply into the other man's shoulder.
Cas groaned softly, lifting his head up enough to free his mouth for a moment, gasping for breath and flexing his jaw once before murmuring out some words of nonsensical approval at Samandriel (in both Enochian and English)-- clear encouragement for more before going back to work on Dean -- more intensely this time, as if it were his personal mission to please his husband. Which, well, it actually was.
Clearly, yes, he liked it.
Somehow that encouragement was enough to get Samandriel to relax and really fuck Castiel. He held his hips in place with one hand to avoid jostling him too much on Dean’s cock (what, it was a concern,) glad for enhanced angelic strength to be able to manage and let his own hips start snapping into Castiel. He bit his lower lip, a groan rough and ragged in his throat while he moved. His other hand slipped from Cas’ shoulder blades to stroke the angel’s poor ignored cock. “You want me to fill you up, big brother?” Lost in this, he was beginning to be certain that Dean wouldn’t actually mind at all.
Besides, it wasn’t as though he wouldn’t enjoy any ‘punishment’ from Lucifer whenever it came. “Feel so good,” he moaned. “All tight and hot and eager for it.” Dean wasn’t the only one who could be absolutely filthy, and Samandriel was quickly picking up that Cas rather liked being spoken to particularly if he didn’t have to do any speaking himself.
That Lucifer wasn’t doing anything at all was rather the point Dean was trying to make. He cried out harder. “Fuck him deeper, Samandriel,” he said, trying to direct even while he received. Cas was at his best when he was too lost to even think about anything properly. Dean reached up and tangled his fingers in Lucifer’s hair, dragging him up for a deep kiss. “Do you even know how much I want your cock in me right now?” he growled between kisses, low enough to be out of Castiel’s hearing and hopefully Samandriel was a bit too distracted still.
He let go of Lucifer’s hair to guide the other man’s hand to his throat. Kissing, biting, more roughness than most people could handle? Those were the things that would drag Dean to begging. Anything less and he could just tune it out and last for far, far too long.
