Finnick presses the flat of his palm where Levi puts his hand on his back. The movement brings him slightly closer, brushing a little more against his erection, and Finnick's eyes flutter shut for a moment. A small hum of arousal escapes his lips. He rarely spends so much time lingering close to someone, unclothed, and not fucking them. It's strange, but the tension of it is delicious as well.

He listens carefully, and it takes a moment to wrap his head around the instructions. Particular, yes, but not unreasonable by any stretch of the imagination. Sex is gross and messy, Finnick knows that as well as anyone, he's just learned to either desensitize himself or find pleasure in those parts through association. He sees it as completely valid to not want to deal with the mess of it, to opt out. In fact, Finnick never thought of that as an option. In a way, Levi setting his boundaries in this moment is opening his mind to... Boundaries in general. Perhaps that's something Finnick could have too! What a fucking concept!

He nods. "Works for me. I'll try my best to be squeaky clean for you." Finnick pays attention to hygiene in the sense of always wanting to look and smell his best, but since meeting Levi, he's also taken more care around hand washing and teeth brushing, unconsciously doing it more often.

"I may be a horndog, but I like to think I have a little more finesse than that," he purrs with a small smile. Seduction is a fine art, and it's always been clear to Finnick that Levi requires more careful attention, and a more gentle approach.

He traces the thumb of his prosthetic hand along the curve of Levi's collarbone, eyes flickering between there and his face.
