Kissing Amber was like falling into the sea: Her body surrendered to the pull of the tide, buoyed by the saltwater, every breath tasting like the ocean. Reese lost all sense of where the surface was. All there was, was this. Amber’s lips, her tongue, her hands stroking back Reese’s hair, curling around her head and holding her steady. If their first kiss had been a bit awkward, that was gone now.
