Summary
A shortage of hormone suppressants causes a brief panic at Tracen Academy. Dorm leader Hishi Amazon helped out as best she could, guiding the other mares through the difficulties of estrus, and provided some extra assistance to fellow dorm leader Fuji Kiseki.
When Narita Brian returns to the academy grounds and finds the mare carrying another stallion's scent, she opts to do something about it.
Hishiama is not complaining.
