A soft M for very vaguely implied sex.
Day 3: Secrets
Her hands ran along the edge of his mask, yearning to rip it away and look at the man underneath.
He grabbed her by the wrist and gently pushed her away, pushing the temptation away with it.
Every secret they kept from each other was a barrier; a tool. As long as they kept secrets from each other, they were at a safe distance. Their little relationship, their… this, was small, manageable. As long as there were secrets keeping them apart, it was only what they allowed it to be.
It hardly seemed fair to Korra. She kept from him her quirks, her interests, her deepest dreams, and in return he kept his identity, his story, his life.
This relationship was not for minor spats and emotional quibbles, though. It was not for coming to an understanding and being on the same wavelength. It was for a short respite and release from all the stressors they faced each day, and he reminded her of that with a thrust.
Their secrets were a wall between them, but their relationship was also a secret, and the secret bound them together.
