Trace couldn't help himself, the rush of rough stubble against his throat, and strong fingers, it made him reach out - a hand curled into his brother's hair harder than he meant it to - but reach out with his essence, too, and pull at the pieces of himself he could sense in his brother's system. He almost couldn't remember what that would do to another organic, it had been so long since Mari that he'd forgotten, but he felt the connection between them stretch and unfold like a blanket to wrap around them, and he sighed, pleased, and let his other hand slide in absent circles down his brother's back.
