He's developing questions of his own - but the way she presses along him, the gasp isn't just on her side, and his torso flutters with the difference in heat and chill. The rocking totally helps things too.

He totally knows what to do, and he gets himself together again after the gasp and reaches over to undo it with deft fingers, used to fulfilling actions just like that one. Clasp undone, the fabric should start to slide off, but he returns his attention to her face, kissing her, licking at her lip to see if she'll let him explore her in return. ]
