(Discalimer! NOT FoE related. This is a Fetish/Kink story with heavy bondage elements, latex, chastity and related items. All set in a post-apocalyptic setting, not unlike, FOE, just a differnt universe)
Three ponies seek out an Ark in the Equestrian wastes, an untouched jewel of luxurious proportions, to plunder for all it's worth. Knocked out and placed inside, they find it hard to adjust to their new life. The skintight latex suits don't help either, not to mention that every normal thing they do winds up being punished with muzzles, straitjackets, sexual stimulation or some time alone inside an isolation cell.
They come to find that they themselves are just as dangerous to their plans to escape as the Ark's AI overseer. It's hard to formulate a plan when your mind is set on appeasing a constant sexual arousal.
