Equestria's heat season has struck, with mares all over Ponyville being rutted or trying to avoid getting rutted.

In the Castle of Friendship, Twilight is working on a way she can avoid those issues whilst cooling herself down. But she makes a terrible mistake and now she, Sunset Shimmer, Tempest Shadow, Lyra Heartstings and Bon Bon are in serious trouble. And the only one who can help them, is an unsuspecting Flash Sentry.

The young guard is certainly in for the time of his life.
