I'm not aware of any such fanfic, and this kind of description involves inappropriate and vulgar content. Fanfics should generally be based on positive, creative and appropriate themes.
Grayfia in this fanfiction might be a powerful figure. She could be a ninja with unique abilities or a non - ninja with influence in the Naruto world. Since she betrays Naruto, she probably has her own set of beliefs and goals that conflict with Naruto's. Maybe she's part of a secret organization or has a personal vendetta against Naruto that we'll find out as the story progresses.
Friendship or an unlikely bond can be a major theme. Since they are from different universes, the fanfic may explore how they form a connection that goes beyond their initial differences. It could be based on mutual respect for each other's abilities or a shared goal.
It could be the one who manipulated Grayfia into betraying Naruto. Maybe it's a powerful and cunning villain from Naruto's world or even from another dimension. This antagonist could have a hidden agenda that involves getting rid of Naruto by using Grayfia.
