On the balcony.
After the heartfelt reunion with her family Sarah went to her bedroom and ran a bad, scrubbing the slime and grime from her exhausted body. She was immensely glad to be home, she felt that she could sleep for days, but once she wrapped herself in the warm blankets of her bed she could do nothing but lie there without sleep. She rolled over, she put her head under her pillow, she even got another blanket, but no matter what she did sleep continued to elude her.
Eventually Sarah gave up on rest, tugged open the doors to her terrace, and stared at the moon. She phased out of thoughtfulness and simply gazed at the glowing white orb taking residence among the stars of the black sky bright with its light. Many moments passed as the cool night air traced Sarah's skin breezily before Katherine knocked on the door.
Sarah barely bothered to turn her head at the noise. "Come in please, it's unlocked."
Katherine slowly turned the elegantly simple doorknob and stepped into the bedroom. Her good sense was seduced away from her by the sight of the beautiful woman in the white dress who's curls shone in the moonlight. "You're stunning," she wonderingly admitted.
Sarah cheeks glowed; like a fire through the darkness Katherine could still make out her shine. "Thank you Katherine. Would you like to join me on the balcony?"
"I'd love too." Katherine approached the princess more gracefully than she had even done before. "If it's not too forward I'd like to take your hand," Katherine suggested.
"I don't think that would be too forward." Sarah reached around Katherine's waist and took her left hand, nudging the pair together.
"If it's not too forward I think that I'd like to kiss you."
Instead of a reply Sarah answered Katherine with a gentle kiss with only the eyes of the moon upon them.
