Heat season has once again come to Ponyville. Every mare is feeling it, and Zecora's stock of potions to relieve it has run out. Fluttershy finds herself without relief, and as luck would have it, her brother decides to come and pay a surprise visit.

He might get a piece of his own sister, if she doesn't break him before that.

Contains: Incest, impregnation, oral, vaginal, and angry sex.
