Soft-vore is a type of content in adult videos that involves role-playing scenarios where one character "swallows" or "digests" another character, usually in a non-violent and often humorous way. It's called "soft" because it typically doesn't involve actual gore or harm to the characters involved. Instead, it is portrayed more as a playful and fantastical act of consumption rather than an aggressive action.
This type of content can include scenarios where a character may be eaten by another, only to reappear unharmed and in good spirits, or situations where characters are swallowed whole but continue their interactions from within the other character's body. This is meant to be a source of pleasure for viewers who enjoy these fantastical scenarios and find them sexually stimulating.
