we were beautiful, by orphan_account

It had all come together tonight. They had fought in perfect, perfect unison, Jace always exactly where Alec needed him to be, Alec always exactly where Jace needed him to be. They had both slipped into a wild uninterruptible series of perfect hits, each at his absolute fastest and strongest, and Alec had felt the fight become an art form. A dance, Alec and Jace the centerpieces, the demons the counterpoint, slain. All the more thrilling for its being a secret. They weren’t on a mission; it was just them and their recklessness, in a fresh new city with fresh new weapons just waiting to be broken in.

Teen, pre-canon. A perfect fight leaves two parabatai tired – and sharing a bed… This is lovely.
