Oh, it has been far too long since Felix has heard Sylvain laugh, and it's all he can do not to ruin his vaguely grumpy act with a smile.

"Hmph. I admit nothing." But of course, he's full of shit, and he's sure Sylvain knows that. Sylvain has always been his favorite menace.

He closes his eyes, a little shiver going down his spine at the breath and soft lips against the sensitive flesh of his neck. A quiet hum of approval is all he provides as a reaction for now, though his free hand moves to thread his fingers into Sylvain's hair.
