The only (verbal) response she makes is a low moan that vibrates around his cock as her head continues to bob. There's a slick, wet sound to it - she's eager to take more and more of him, her tongue dragging against and around the sensitive tip - and then she slides her head forward until she's taken all of him, until she's practically choking, until her nose is pressed in against his belly and she looks up at him with those wide, "innocent" eyes of hers. She's playing a part, of course - but that's what makes this fun, right?
