That confirmation is as good as any confession he could make. At least as far as she's concerned. Her moans are swallowed up by the kiss and she returns it with just as much emotion and passion for precisely the same reason. If this is all they've got then she wants him to know how she feels.

Her nails scrape against his back a little and she runs her hand up the back of his neck, intentionally hitting that sensitive spot. Rushed doesn't mean they can't both at least enjoy this moment and if he wants to stop thinking, she's going to help him.

Protection never crosses her mind because she's never considered that they're compatible that way.
