Aliasing breasts_against_glass → breasts_on_glass
Link to alias

Reason:

breasts against glass is a tag that implies that the breasts are right up against a pane of glass. While wild breasts on glass is much more vague only saying that they're near or close to glass not suggesting at all that it is right next to it or bunched up against it.

EDIT: The tag alias breasts_against_glass -> breasts_on_glass (forum #271160) has been approved by @bitWolfy.
