School girl unconsciously showing underwear or camel toe

These are girls who inadvertently show their crotches, panties, etc. in gym clothes, school swimsuits, etc. In most cases, it is not intentional, but rather unnoticed or just now noticed.

There is no genitalia exposure.

Same as on FANZA in Japan. https://www.dmm.co.jp/dc/doujin/-/detail/=/cid=d_245752/
