Scorching hot, like sherriaisling said. I couldn't put it better into words myself. Also, this fic is my little dream of Nami\Vivi coming true. Which means, to thumbs up girl! ^^

Crits? Well, there's this one sentence which has a few typos. You might want to check it:
Tonight she feels herself seize and convulse and soar and she presses her hands firmly against her eyes until she sees stars.
Other than that, I see nothing wrong with this piece. Keep up the good work^^
