Equestria has a problem. A Big problem. For several thousand years the world was cursed never to receive a male heir, and only through will of the Sun Princess Celestia and the advanced magical sciences, was the world able to allow a means of procreation for all the races. As efficient as it was, Twilight Sparkle was not satisfied with this arrangement, and summoned a human male from another world. Unfortunately she did not consider the side effects of this, and now every female that he touches goes into an irresistible heat.

(Takes place in season one.)
