Brother's Keeper

"It isn't easy, being my brother's keeper. But I'll do whatever it takes to keep him safe." Since Cal returned from wherever the Grendels took him, he hasn't spoken a single word. He hasn't slept through a single night. But when Cal gets an idea in his head that he needs to keep Niko safe, that's when things really go off the rails. Warnings:spanking, Cal's language, angst.
