Samandriel stared at Dean for a moment and then realized rather abruptly what was going to happen. He nodded and perhaps it was a waste of energy, but flight was the most efficient way to manage. Retrieving the cloth (cloths, actually, one nice and soapy and the other just wet,) he reappeared in front of Dean and set about heading off what could possibly end in mental disaster for poor Castiel. Samandriel washed his dick as best as he could and used a bit of angel mojo to take care of anything that might still worry Cas and did it in full view of the other angel so he could see for sure that it would be Safe and Clean.
Castiel's shoulders lost their stiffness over that, and he offered a look that was so ridiculously grateful that there were probably not enough words to properly describe it. "Thank you," he murmured to no one in particular before seating himself on the floor between Dean's legs and resting his forehead on his husband's thigh.
Lucifer, bemused and a little touched, only continued to run his fingers through Dean's hair.
Dean stopped touching himself so Cas would have room to move. He threaded his fingers through his husband’s hair, trying to calm and steady him gently. He tipped back and leaned into Lucifer’s touch. “God, you three,” he groaned appreciatively.
Samandriel moved away and went to go settle himself by Lucifer, stroking him teasingly. It wouldn’t be fair to not see to his boyfriend’s needs as well even if Lucifer was trying not to acknowledge them. He really wanted to just sit on his cock, but he didn’t think Dean or Lucifer would appreciate that properly just then, distracting at all.
Cas, clearly more pleased at the idea of being a participant when it came to Dean instead being forced to watch, settled comfortably into the task of licking and sucking Dean's cock. Even he was aware that the noises he was making over it were a bit on the pornographic side.
"Slow," Lucifer directed at Cas, like it was the most obvious thing on the planet. But he was silently pleased with himself for several reasons, and decided that he could take a moment to get his own reward in kissing Samandriel -- not at all slowly. Later, when they were alone again, he'd give his angel something more.
Samandriel enjoyed that kiss while it lasted and moved back around behind Cas, running fingers gently down his back, over his rear teasing him hopefully eventually back to hardness. What? Lucifer really did have a sadistic streak when it came to making things difficult for people, and selfishly Samandriel wanted to give Lucifer a taste of his own medicine. Sort of. Mostly, he just wanted that cock to himself as soon as Dean and Cas were gone.
The fingers still in his hair were pushing Dean a bit towards the needy side. He whined as he leaned into it, hips pushing up just a hair as well. “Fuck, Cas,” he groaned. “Lucifer.” He looked over at the other man, fingers still moving in Castiel’s hair.
Cas made little mewling noises around Dean but dutifully (right, like it was difficult) kept right on, going lower and letting his tongue curve around the base of Dean's cock. His jaw was going to be a bit sore after this, but he certainly didn't seem to mind. Samandriel's fingers weren't so much distraction as a nice additive.
Lucifer gave Samandriel a very wry expression and a raised eyebrow. "Yes, Dean?" He asked, although didn't quite take his eyes away from his boyfriend.
