There is a sound tag usage, but here we will describe the contents of the R-18 series.
An R-18 type tag that can be attached to a picture of a female genitalia being expanded with hands or equipment, and is a type of propensity.
It used to be a genre of "expansion", but it has become established as an expansion with the onomatopoeia of "kupaa".
If it is not a female genitalia but an anal, it is called an anal kupaa, but in this case, since a mosaic is not required, it is drawn as often as or more often than a kupaa.
Not limited to fingers, it may be spread using tape or equipment, and in the case of anal, it can be easily removed by pulling out the anal dildo or anal plug.
In addition, even if the onomatopoeia is not attached, it is classified as "Kupaa" if it is the situation or if the female genitals are widespread.
Overseas, it is written as "Spread pussy" or "kupa". The former is often used for photographs, and the latter is often used for illustrations made in Japan. Also, "spread beaver" in hide's band "hide with spread beaver" is a jargon for kupaa. According to him, "a band name that is embarrassing no matter where you go".
