Caleb listened, paying close attention to everything Caduceus said as he guided and reassured him. He knew it all already - that he could stop anything, no matter when, if he was feeling the least bit uncomfortable - but he still liked hearing it. The only words he could think of to use as a trigger were all in Zemnian, but he supposed that worked as well as anything else. It didn't seem like he had to think of anything just then, though. He could take his time and think of something he wouldn't say on accident. Until then, he couldn't imagine anything he might need to use it on. There were thoughts, yes, things that Caleb was well aware would push him to his absolute limit. But they were just thoughts right now. He wasn't ready to explore those things yet. And he knew Caduceus would never suggest them either.
He nuzzled his nose against Caduceus', smiling softly, and curled a little bit of pink hair around his fingers. "Whenever you want," he answered. "Even if we're not in private. I don't mind." And Caleb was a little bit of an exhibitionist anyhow. He liked the idea of being seeing Caducues' hands on him and knowing who had staked a claim over him. Not that anyone else was looking, but it was still nice. The idea still made a soft flicker of heat rise up in his chest. He also really enjoyed hearing Caduceus say things that were just a little filthy. The sort of things that came out of Jester or Beau's mouths uninhibited (and didn't so much as make him flinch, though it did sometimes make him giggle) sounded obscene when Caduceus said them. He loved it. It made him feel like he knew something that no one else did.
"I wouldn't want to be doing this with anyone else," he said, lifting up a little so he could press a kiss to the edge of Caduceus' ear. If touching was intimate, he wondered what kissing would be like. "Do you want me to take this off?" He tugged at his own shirt, the same sort of loose, thin fabric he'd always worn back home, but without the layers and layers over it hiding him from the world. He'd relaxed a lot here, and losing the coat and scarf and layers of shirts showed it. While he was waiting for Caduceus to decide if the shirt needed to come off, he slid his own hands back inside the thin robe Caduceus wore and stroked his fingers over soft fur, letting his nails trail softly through the short plush parts towards where it grew in thicker.
He could feel the first hint of Caduceus' arousal pressing up between his legs and he wanted that. He also wanted far less fabric between the two of them so he could really, truly feel it as it started to nudge up towards him. But that was always going to be a thing for Caleb - he was always going to want far, far more than he could do at any one time. Too ambitious for his own good, even in bed. But no one here seemed to have a problem with it.
