"Moe" is a Japanese term commonly used in the context of anime and manga. It stands for "cuteness" or "adorableness." In porn videos, the term "moe" refers to a particular fetish or preference for characters with childlike features or who are portrayed as young or innocent. The characters may appear to be teenagers or even younger but maintain an attractive or seductive quality to them. This tag is often used by fans of this specific sub-genre, where the focus is on the appeal of youthful appearances rather than explicit sexual content.
