female ejaculation
The expulsion of fluid from the vagina during or after an orgasm. Colloquially known as 'squirting' or 'gushing'.
It can be hard to tell whether an image contains female ejaculation or peeing, especially if the picture is monochrome. Female ejaculate is usually drawn white or clear as a strong gush, and there will usually be less of it than there would be if the subject was peeing. If you aren't sure which it is, use your best judgment when tagging.
Not to be confused with the squirting liquid tag, which is for non-sexual expulsion of liquids. This tag implies a vagina, in case of a futanari ejaculating ejaculating while penetrated shall be used instead.
