The porn video tag "totally-spies-hentai" refers to a specific category of adult content that combines elements from the popular animated TV series "Totally Spies!" and Japanese anime/manga style art called hentai. Hentai is known for its explicit and often fantastical sexual themes, while "Totally Spies!" features a group of teenage girls who work as secret agents fighting villains. The combination of these two concepts in the video tag suggests that the content will involve sexually explicit scenes with characters designed in a similar style to the original show, engaging in various fetish-related activities or situations. This type of content is intended for adult audiences who enjoy combining their love for animation and hentai with familiar characters from a popular series like "Totally Spies!".
