I decided to change the tags on this one, at first I thought it was implied futanari but looking on Pixiv again, the artist gives no indication that it is futa, he just tagged it yuri and レズ (lez/lesbian).

I actually think it's hotter to think of it as a girl ejaculating on another girls face while she performs cunnilingus. Maybe we need some sort of female_facial, pussy_juice_facial, or pussy_juice_on_face tag.

There is a video a woman squirting so hard it is like a water hose. All while standing up. So there it is a possibility.

I don't, even saliva on the face bothers me. Also, I think the female_ejaculation tag is enough, it's not like this is a common occurence.
