When mares go into an unwanted heat cycle, they head for Ponyville’s spa, where a specially prepared brew of strong herbs and a gentle massage will set things right. This special brew makes them dizzy, dreamy, and very susceptible to suggestion ... which becomes a bit of a problem when the new stallion temporarily hired to help through the heat season figures it out. He’ll end up using that information in some very inappropriate ways.

Contains: massage, mares in heat, loss of virginity, impregnation, lots of non-con, sex with drugged mares, hypnosis/mind control, vanilla sex, sloppy seconds, MFF thresome, MMFF foursome, mention of non-con harem/sex dungeon.
