Caleb immediately moved to stroke and kiss Caduceus' ears when he saw them droop, pouring all the love he had into them before he met the kiss with a pleased hum. "You're perfect," he said. "There's nothing to forgive." And there wasn't. It had been a little slip and it didn't hurt him any. He liked that Caduceus had forgotten himself, that he could have such an effect on him that it had entirely slipped his mind. It brought him a sense of pride, strange as it was, to be able to do that to anyone but much moreso Caduceus, who always seemed to be so put together and in control of himself. He wanted to find other ways of making him lose control.
A different thrill entirely when Caduceus' voice dropped so low and Caleb felt that rumble run through them both. He blushed, heat rising up to his face and neck and working its way slowly down his chest. "Nein," he breathed, shaking his head softly as he looked wide-eyed back up at the other man. "I want more." It was such a simple statement and yet Caleb had been shamed so much for it in the past, it was nearly a miracle that he could say it at all. But Caduceus was safe, Caduceus took care of him, had never judged him, or punished him for his wants and ambitions. He only ever did his best to give Caleb anything he asked for. It just made Caleb all the more insatiable, knowing that he could have it when he asked. And, gods, it was the most incredible thing when he did get it too.
He almost missed the swear that fell from Caduceus' lips, and might have had it not registered in some part of his brain and made his cock twitch again. He slipped his hand from between their bodies, settling as far down as he could and rolling his hips slowly. The gentle curve rubbed against places that made Caleb see stars, but he was less concerned with that than leaning forward and latching his lips and teeth against the newly-exposed skin of Caduceus' neck. He trailed his tongue up the expanse of his throat, nipped at his jaw, and then down along the side of his neck again. He wasn't even thinking about what he was doing, he was just going off instinct and pure need. And what he needed was to have his mouth anywhere on Caduceus' body that he could reach.
"Bitte," he murmured again, moaning softly into Caduceus' neck. "Please. More." The implication that Caduceus didn't need to be gentle with him was clear in his voice. He wouldn't be trying to press himself down with such desperation if he didn't want it. He braced his now-free hand on Caduceus' waist, just above his hip, using the little bit of leverage he had to rub against his stomach and try to get a little bit of friction. His own cock felt heavy, almost pained in the need for relief, but he loved that feeling. He loved the heat of being stretched out and the pressure of Caduceus' fingers on his hips. It wasn't a self-punishing desire for pain, it was just that the pressure and the ache seemed to release something he always kept balled up tight inside of himself.
