Twilight Sparkle is a studious mare, and she just wants to get her homework done, if only her heat would allow her. Fed up with her body's constant attempts to stymie her academic advancement she goes to Celestia in order to have her heat magically subdued. In doing so she also gives the alicorn even more power over her life.
As the years pass this power grows until eventually, it begins to get in the way of her friends lives, where it inadvertently becomes a vehicle for great change.

Kinks. Lesbianism, f/f, polyamory, toys, anal, oral, cunnulingus, futa, rough, public fucking, 3 dicks 1 mare, 4 dicks one mare, double anal, double oral, public use, cum swapping, scent, incest and lots and lots of orgasm denial. (also probably more I'm forgetting, also these are all the kinks in the first eight chapters so be patient if you see a kink here that isnt in the story yet, its coming.).
