Yes, there might be some out there. Fanfic websites often have a wide variety of stories written by fans. You could try searching on popular fanfic platforms like Archive of Our Own. However, the availability can vary depending on the popularity of the pairing within the fan community.
The themes can be quite diverse. It could have a theme of friendship evolving into something more. Maybe they start as adversaries but through shared experiences, a kiss becomes a moment of deep connection. There could also be a theme of trust. A kiss might be a sign of the growing trust between them despite their initial differences. And of course, there could be a theme of exploring the unexplored relationship between two powerful female characters in the Star Wars lore.
One challenge is getting their personalities right. Ahsoka is a Jedi with strong moral principles, while Ventress is a former Sith assassin. Balancing their different outlooks can be tricky.
Perhaps there could be a story set in a parallel universe where Ahsoka and Ventress are friends from the start. They could go on adventures together, facing challenges unique to that universe, like strange new Force - based creatures or a powerful, corrupt organization.
There could also be a story set in an alternate universe where Ahsoka and Ventress are both outcasts. They form a bond while trying to survive in a galaxy that doesn't trust either of them. This could lead to character development for both as they learn from each other's strengths and weaknesses.
One possibility could be a story where Ahsoka and Sabine have been through many battles together. Their relationship has grown stronger over time. The kiss could be a moment of realization of their deep emotional connection. Maybe they've just survived a very dangerous situation and in the heat of the moment, their feelings come to the surface and they share a kiss as a sign of their newfound closeness.
Their relationship may develop as they face common enemies. For example, they might have to team up against a powerful Sith or a group of marauders. During these battles, they learn to trust each other's instincts. Sabine might rely on Ahsoka's Jedi wisdom and Ahsoka might be impressed by Sabine's tenacity. This trust and admiration could be the foundation for their relationship to grow, leading up to the kiss.
In fanfics about Ventress and Anakin, their relationship is often complex. They are on opposite sides in the Star Wars universe, but fanfic writers like to explore what could happen if they had more interactions. Sometimes they might be portrayed as rivals with a grudging respect for each other's skills.
In fanfiction, Ahsoka might be portrayed as more conflicted about the Jedi Code. For example, she could be more open to Ventress's ideas about power and freedom, which is different from her more by - the - book nature in canon. Ventress, on the other hand, could be shown with a softer side, perhaps having more remorse for her past actions than she does in the official storylines.
In fanfic, the Ventress - Anakin dynamic can also be used to explore the grey areas between the light and dark sides of the Force. Their encounters can make readers think about whether good and evil are always so clearly defined. For instance, Ventress might show Anakin that there are times when the Jedi code may not be the most practical solution, and this could make Anakin question his own beliefs and allegiances.
