"You want to know what I think about?! Cas' voice was merely a whisper now, and Dean had to admit he was unnerved. He could feel Cas inside him and wanted more.
"What?" Dean managed to choke out, and Cas smirked at Dean's vulnerability.
"I think about you, like this, beneath me. I think about you as a writhing, needy mess, submitting yourself to me. I know you, Dean. I know how controlling you like to be. But right now, I want you to let go. Let me dominate you. Feel it. Feel me." Cas' eyes were darkened pools of both lust and curiosity. He watched as Dean accepted Cas' dominance and thus he visibly tensed. Castiel wasn't going to let Dean be satisfied that easily, he knew Dean wanted more and more.
"Cas, please-" Dean could hear in his own voice how much he didn't sound like himself. He sounded desperate. He was breathing heavily now; the longing was insidious. Dean's vision was dominated by Cas' figure, he could see in his expression that he was enjoying this – enjoying having power over Dean's pleasure. Dean couldn't ignore the pride that was in Cas' expression, and he knew that it was because he was able to do this to Dean. Dean knew he wasn't going to be satisfied any time soon; Cas wanted this experience to be intense. And so it was; Dean waited and waited, hearing the own desperation in his whimpers as Cas drew in and out of him painfully slowly. Cas won't let him have it yet. Dean can feel Cas' hands over his thighs, his stomach, and then they are pinning him down into the bed by his waist. Cas doesn't let his eyes leave Dean, he wants to study his every move as Dean is reaching and reaching, panting faster and faster. Cas watched as the hunter below him breaks apart in every way that a human possibly could; Dean's thick-skinned façade is completely torn away and all that is here right now is a weak, wanting, seductive version of Dean that Cas has to admit he completely loves and desires. Cas feels thoroughly proud that he is the reason Dean is groaning and almost yelling. Dean can feel it so close; the tension between both himself and his angel has all been building up to this one moment – this one moment filled with all kinds of emotions from protection, to unresolved anger, to adoration, to admiration to lust – Dean could all of a sudden feel every single moment they had ever shared, all combining in this one indescribable moment.
"Cas, please-" Dean repeated, but this time he didn't sound desperate, he sounded angrier, and Cas responded by pushing one hand beneath Dean's back in a supporting gesture. They were now in an embrace, and Dean knew that Cas could feel all of these emotions too. Their bond was so distinctive that they could feel it with every inch of their bodies.
"Dean, come on, let go, now." Cas pick up the pace, all the while still watching Dean, and Dean threw his head back in pleasure. Dean grabs Cas hard while holding his breath as he falls to pieces under his blue gaze. Cas' hands are still on Dean's waist, and he'll never forget the way he made Dean come undone this night – he saw the look of adoration, lust and desire in his eyes and he sure will see it again.
