It was just that Caduceus got Caleb in the most wonderful way. Both in the sense that he simply understood what Caleb needed and everything he did in response to that had Caleb more and more devoted to him with each word. He'd always had the desire to be possessed, though. He hadn't always trusted the right people with that possession, but that was all different now. He trusted Caduceus to take care of him, to look after and guide him, to know what was good for his safety and health better than even Caleb himself did. That might have been a lot to lay in someone's lap so quickly but the truth was that Caduceus had been doing it since the day they met. He had always been a source of confidence and safety for Caleb. It had only become more intimate since coming here.
"I do," Caleb smirked softly, reaching up to push his hair out of his face. "I like the sound of your voice, too, when you get firm with me. It's striking. I think the sound alone does as much for me as what you say."
He was getting better at this, too - the whole process of expressing what he liked and what he wanted. But Caduceus had asked him to do it and he was so good at being open with Caleb, it felt like something he should also be able to do for him. Right now, though, Caduceus was the one giving the instructions. Caleb obediently helped strip his shirt off over his head and then leaned back - one hand braced between Caduceus' legs - to watch him move and slowly work his pants open. He was already straining at the fabric and had been for some time. It was a relief to have a little more room.
Pretty wasn't really a word that Caleb had ever associated himself with. He might have been handsome in an awkward sort of way, at the right angles, but the way Caduceus said it made him believe that he believed it. That it could be true. And he wanted to be that for him. He tried, then, to be a little more graceful as he shifted backward off Caduceus' lap to answer the request, stretching his legs out and bracing both hands behind him so he could lift his hips up and help with his pants. As much as he wanted to reach down and adjust himself first, he waited, letting the air and Caduceus' gaze touch him first. Then he slowly reached forward and brushed a hand over himself and down between his legs.
It was a trick he'd learned ages ago, but a little prestidigitation in just the right place and Caleb was already slick enough to accommodate the press of Caduceus' cock against him when he did finally crawl back into his lap. There was no need for prolonged preparation unless Caduceus wanted to touch him. What Caleb really wanted was just to feel him slowly slide inside.
