Creatures from other worlds, little-known by the population of Equestria, are going around the country, abducting ponies and conducting what are, allegedly, experiments. Maybe due to a bizarre scientific conduct, maybe due to them not wanting to lose face in any way, or may because they aren't interested in doing it by hand/tentacle/telekinesis, they are letting some specially-designed machines do the deeds they want to do.

The inhabitants of Equestria are less than pleased.

Quite a lot of weird crap this story, so please check the list before you start reading.

These are in almost all chapters:

Abduction. Dubious consent. Sex machines. Aphrodisiac. Piercings.
