A sex animation of Vivian by theboogie, check him out here!

Vivian is the youngest of the three Shadow Sirens in Paper Mario: The Thousand-Year Door. Unlike her sisters, Vivian is benevolent, compassionate, and gentle in her interactions with other people. Vivian and her sisters seem to have been somehow cognate to the Shadow Queen prior to the queen’s confinement, though the exact nature of this relationship is unknown. She is consistently put down by her oldest sister.
