About This File
A CG set by artist mani, purchased from this site. Written from a first-person perspective of a girl named Ami, who needs to pee during a swimming class.
The set includes a situation where she wets herself overground, and another where she pees through her school swimsuit underwater.
The set is zipped with a version including text (only in Japanese) and another with the text omitted (under "文章無し").
