The Second Turn of the Lock

A modern, realistic AU. You grew up with Caleb, the older brother you share no blood with, and as adults you still live under the same roof. Lately you seem to be seeing another man, and Caleb has read the messages on your phone. That night, the front door locks a second time behind you. The brother who always saved you dinner and indulged you with a smile is done holding back: he means to stop you, rein you in, and take you back from someone else, bit by bit.
