He doesn't mind not getting an answer, because really he just said that to tease her, add more fuel to the way he's touching her between her legs. The sounds he gets in response are reward enough as it is, maybe even more so than she realizes.

Planting a trail of kisses on her face, his lips move from her cheek to her ear, tongue drawing along the shell, then he nibbles lightly on it. His fingers press a little more presently past her folds, so easily sliding along her wet slit as he starts moving a little faster, teasing her in just the right spots, trying to build up to something more. His fingers do pause every once or twice when they slide close to the rim of her open, curling just barely until the fingertips dip a little into her, but no more than that, soon drawing back up to her clit again.
