Big Naturals

You smoke a bag of pipeweed and turn your focus inward, enhancing your form in the most wizardly way. The cup size of every breast or breast-analogue you possess permanently increases by 1d4 inches. Once the spell has completed, this change is not magical in nature and cannot be dispelled. If cast by a creature that does not possess mammary glands or an analogue thereof, the spell fails.

When cast with a spell slot above 3rd level, the increase in cup size is raised by an additional d4 for each level above 3rd.
