In the distant future, humans have found Equestria in a far-off corner of Hoag's Object (Or more accurately, Equestria found them). In this world, however, the ponies are amazonian in both size and shape.

Now, in the year 2627, one unlucky lucky human, a teacher by the name of Bryce Owens, and his roommates Lou Singleton and Hugo Schaefer, unwillingly become the harem of Pinny Lane, a bowling champion famous for her skills, success, and size. For Pinny is no average mare, being enormous even by the standards of her own race. The scandal of the 27th century ensues.
