Castiel was a shaking mess of orgasm, screaming for Dean and clutching and grasping, spurting rope after rope of ejaculate till finally, breathlessly it slowed. Dean was nuzzling his head under Castiel's jaw as he caught his breath, then kissing his damp forehead. "There you go, baby. I still got you." Still placing soft kisses, still touching him gently as aftershocks continued.
The angel was too blissed out to respond, and instead wrapped his arms around Dean and closed his eyes. His last night on Earth, or anywhere, he supposed. They'd have to confront Raphael in only a few hours, and now, only now had they opened up to one another.
Love you so much, Cas.
He held Dean closer, needing his warmth and his words and the tender kisses his human was planting along Castiel's collarbone.
Love you so much.
He felt Dean's lips on his again, grounding him, seeking reciprocation, asking for reply. The angel whispered sweetly against his lover's mouth, and I love you, I have loved you for so long. His hands were wandering across Dean's strong shoulders, to his neck, and they entangled their bare legs as the hunter's kiss became more insistent. As Castiel was softening, coming back to himself, evidence of Dean's need pressed hard into his thigh. His lover was moving against him, stroking hips and sides, then kneading his outer thighs, and the man's self-control was plainly at its end. The lustful motion of his hips increased, and he was stifling groans, squeezing his eyes shut, kisses now fraught with the sharpness of teeth.
Castiel placed his hands softly on either side of Dean's face and the human's eyes fluttered open, glossed with passion. "Cas, God I need you. Need you now."
"Yes, Dean. Anything. What do you need?"
The hunter sucked in a sharp breath, and a look of doubt shadowed his eyes. He stopped moving and backed away a few inches, skin contact all but broken. Castiel's heart sank. Had he said something wrong? He'd never had such a relationship, and worried he should already know what Dean needed. Was he failing his human, helpless to fulfill the man's yearning? Perhaps he had put too much faith in their bond. He should have been prepared for the possibility that his profound lack of experience would hurt Dean. Ten thousand years of humanity's sex acts hadn't done anything to help him understand the cues, the body language or reactions Dean was having.
"Cas. You're doing things to me - I'm so sorry, Cas, I pushed you into this. You're a freakin' Angel of the Lord, and I was about to - I don't want you to regret this." He touched Castiel's cheek, but his expression hardened and he looked away.
"I don't understand, Dean. There's nothing regrettable about loving another being. We are connected. I want more than anything right now to bring you pleasure." Castiel gently raised Dean's chin and moved to make eye contact again. Dean still looked uncertain, but allowed Castiel to brush their lips together.
"But it seems so, I dunno, lewd. Humans are gross, man." Castiel's eyes smiled at this. The corner of Dean's mouth twitched up hopefully. "Are you sure? I want you to be a hundred percent. I don't wanna hurt you, Cas."
"Yes, I'm absolutely certain. I just need you to show me. Please."
Dean was biting the inside of his lower lip, and Castiel could see he was letting himself be won over. Then the mischievous glint in Dean's eye, the one Castiel couldn't get enough of, returned. "I can show you, Cas. That's not gonna be a problem."
Then there was a hand on each of Castiel's hips, and a velvety, wet heat enveloped his now-soft penis. It sent a shock of electricity through him, and he looked down to see Dean's lips wrapped around his member, the vision aligning with a sensation he couldn't describe. It was a stinging sort of pleasure at first, he felt almost too sensitive, but as the soft movement of Dean's mouth continued, as his tongue slicked over his shaft and softly swiped around the head, it began to feel good again. Really good. The attention drew a delighted moan from him, and he felt blood rushing again to that place, and something was trying to tighten, but he was still weak.
"That is ... astounding." Castiel had pressed his head back into the mattress, chin pressing awkwardly down, unable to look away from what was being done to his body. He satisfied the urge to touch the one making him feel this way by wisping fingers through his hair. "You were right, Dean." Words were again coming less easily, and Dean peered up at him, never stopping his steady motion. "Were right about this." He gazed into sparkling green eyes, which stared hotly back at him. He thought he could see Dean's left hand touching his own member, but he seemed to stop himself, and made one final slow, deep stroke over the angel's now very hard erection.
Dean crawled back up to face his partner and planted a wet, hot kiss on Castiel's lips. It tasted so different, salty and human, and the angel gleaned that this was what he tasted like. Dean was crushing their mouths together, letting their hard cocks slip against one another. A hand cupped and lightly tugged his testicles, then wrapped partway around both their cocks. They found a little friction this way, and Castiel felt the hunter smile against his kiss. Again his hips seemed to be moving on their own, jutting up into Dean's gently fisted hand. Dean leaned down and nipped at Castiel's ear.
"How does that feel, Cas? You feel how hard I am for you? Can you feel the pulse in my dick?"
"Yes Dean, and I want more. I know what I want, I just need you to guide me." Dean released his grip and trailed his middle fingertip down to the still slick hole Cas was so focused on.
"Tell me what you want, Cas. Am I getting warm?" Thick-voiced, he kept his mouth close to Castiel's ear. He was at once licking and softly biting at Castiel's neck, and applying a firm pressure to the angel's opening, making little circles around the puckered rim. This was so exciting to Castiel, Dean's questioning him, using words to stimulate. But he was also unsure how to play the game. What would stimulate Dean's imagination?
"You're getting warm. I want to feel you inside me," he tried. Dean's low growl told him it was a good start.
"My finger?" the man continued huskily, gently probing with the tip of his finger, not yet pushing through the little tense ring of muscle. Castiel felt his hips raise on their own.
