If this looks familiar, it's because you may have seen it on my tumblr blog.
Pretty much some simple, tame smut with no real plot.
She was wearing nothing but a robe when he walked into his room.
She threw her arms around him with warmth that he hadn't experienced in over twenty years. She pulled his hood down and kissed the side of his head, because his mask was covering his face.
It had been her first day of living in his quarters. Only his highest-ranking officers knew that she was sharing a room with him. The rest of his followers thought she was in some high security prison cell.
"Welcome back," she murmured into his ear in a way that made him shudder. She began peppering his neck with kisses.
"My, you're eager today, aren't you?" he said. There was no need to be the imposing revolution leader around her anymore.
"I realized that I never properly thanked you," she said. She took a few steps back and untied the robe.
"For what, Korra?" he asked.
"For ridding me of my bending," she said, twiddling her fingers, "for showing me the evils of the bending oppressors. And for forgiving me, despite how I fought you in the past." She blushed and looked away. "I don't… have much to offer you in return, but you can use my body as you wish."
He took off his mask so that she could see him smile. She shrugged off the robe and touched his cheek.
"You're so handsome. It's such a shame that you have to hide your face behind a mask all the time, though I understand why you do it," he grabbed her wrist and pulled her towards him for a passionate kiss.
As their lips met, she helped him pull his clothes off. When he was naked, he broke away from the kiss and led her to the bed.
She laid on her back let him do as he pleased, moaning his name—his fake one, the one he invented—and only when she reached her peak of pleasure did she cry out his birth name.
Amon wasn't sure when he had put his hand down his pants, or when his hand had become covered in his seed, but he was eternally thankful that the door to his office was locked.
