Riley's nostrils flared and his eyes widened, large and amber once again. He looked up at Tao with a wild expression - he was feeling a bloodlust the likes of which he had always wanted to repress, the heart of the wolf raging in his chest. He let out a snort and growled again, pressing his nose into Tao's cheek. He dragged his nails down the vampire's back and bared his teeth, turning his head to line his mouth up over the flesh of his shoulder. He let out a final growl that had no trace of his human voice in it and lurched his head forward, snapping his jaws in a savage bite that tore viciously at Tao's skin and caused his mouth to almost immediately be washed in blood.
