Please do not apply the "cowgirl" tag to this gallery.
While it's true that the gallery features cowgirls (as in the female counterparts of cowboys), the "cowgirl" tag is currently defined in e-hentai to mean girls with cow features or wearing cow costumes.
If a girl with cow features or costume happens to appear in a future update (and passes presence), then the "cowgirl" tag will become valid.
