Mitsuyubi

Mitsuyubi, often romanized as mitsu yubi, is a Japanese term that refers to the act of inserting three fingers into a bodily orifice, usually the vagina or anus. It is considered a sexual act and is commonly categorized as a form of anal or vaginal fingering. The term is most frequently encountered within the context of adult entertainment, particularly in pornographic videos and manga, but may occasionally appear in other media. The act is often associated with heightened sexual pleasure and is considered a relatively advanced or intense form of digital penetration. The explicit nature of the act means it is not generally discussed in polite conversation outside of relevant contexts.
