There's a fine line with him, between smugness and general contentment. It's possible he's experiencing a blend of both, on top of the general feelings of lust and affection. Either way, he'll take that whine and that swearing as compliments. His eyes squeeze shut briefly; it's both touching and amusing that she's picked up the language, especially since oh fuck me is not, technically, a useful phrase in her role as his guard.

(In her role as his consort, though, whenever they do formalize it? Absolutely essential.)

He's going to need either some kind of attention from her, or a cold shower, but that can wait. Their past experiences have taught him quite a lot about her tolerances, and he's confident she can take more than one climax, as long as she wants to. He focuses his tongue on her clit, keeping a steady rhythm, but then, as if he's read her mind, his fingers slide gently between her labia. Its almost like a tease, the way he strokes around her entrance, but really he's just aware that his fingers are always cold at first touch. Warming himself with the heat that radiates from her body before penetrating deeper seems like the considerate thing to do.

The impatient sounds convince him consideration is not exactly what's on her mind, though, and a moment later he presses his first two fingers into her cunt, slow and easy and deep. There's a couple emphatic sounds that escape his mouth, then, even as he licks at her. She is scorching, soaked, and it's glorious.
