Luna continued unbuttoning his shirt till it hung open on his chest. She bought her other palm up to meet his newly exposed skin. Her touch was electrifying, his eyes were closed but he could feel her everywhere, consuming him from the outside in. His regular heart thudded loudly under her touch and he felt it surely, but there in the corner of his mind, he felt another tug, one that wasn't created by Luna's soft hands. It resided deep within, under the layers of sinew and flesh. The beat of a second heart, thrumming erratically, quicker than his human heart, racing at double speed, as loud as a ticking watch in a silent room.
