The words seem to prickle along his spine, coil in the pit of his stomach briefly. Perhaps some months ago, he might not have been able to tell the difference between feeling flattered and alarmed - it's easier, now, but there's still a little bit of paranoia that flashes through the pleasure; he hadn't really been trying to do anything in particular, but through his slow-going experimentation with Erwin, Levi's come to realize that arousal is sometimes (often) a very fickle thing for him.

But just hearing that there's no expectation would be arousing in and of itself, if it didn't give him so much relief.

For a moment or two, he just stares at Finnick a bit, almost in a little bit of disbelief. But then something between his shoulders unlocks, a worry he hadn't really realized he'd been carrying, and he cups one soft cheek in his palm as he lays a firmer kiss on those sweet, patient lips.

"Thanks," he mumbles from just a breath away when they part. Gathering some courage, Levi continues, staying too close to really look at Finnick, though. "Don't mind f'you are...'n happy to get you off. But...don't always want anything back."
