Felix does understand; Sylvain didn't have to say anything at all to ensure that. He smiles and leans into Sylvain's hand. "Hmph. I'm not offering, I'm demanding."

He straightens up on his knees so he can lean down, arms still wrapped around Sylvain's neck, and kiss him. Usually, Felix kisses like he does anything else - hard and fast, almost aggressive, like a challenge. Now, though, he takes his time. It's still firm and sure, still passionate, but slow and indulgent, too. It's for both their sakes, really - this is the first time he's been able to kiss Sylvain in months and he wants it to last, dammit.

It doesn't take long for him to coax Sylvain into parting his lips so they can deepen it. If the other man doesn't care about taking it slow, then hell if Felix is going to bother. He also doesn't bother to hold back with his intimate knowledge of exactly what Sylvain likes in a kiss.
