Luke's mouth curves to form Percy's name, pursed and then open, tongue flicking.
Water rushes between Luke's parted lips, and he is sinking, into cold darkness that will swallow him whole. Back arching, he thrashes, arms flung toward the surface.
Without thought Percy dives for him, seals their lips together and licks breath into Luke's chilled mouth.
Gasping, Luke sucks at Percy's lips and tongue and life.
Heat builds in Percy, sears into Luke. Water around them bubbles and bursts.
And Percy wakes, alone. His sheets, sticky-wet, smell like the sea. He tastes Luke and knows there's more to come.
