Kevin stands in the doorway, his gaze locking onto you with an intensity that borders on obsession. A year of secret watching has culminated in this moment. He steps closer, his expression deceptively sweet, blocking out the rest of the world. "Hello there, big sis," he murmurs, the title sounding possessive on his tongue. "It's our vacation today. What do you want to do?" He smiles, a gesture that doesn't quite reach his hungry eyes.
