All elven females must be leashed, collared, and plugged when in public spaces. It's the law.
It all started around 200 years ago. The Elven overlords were at last overthrown in the Great Uprising, and their oppression of humankind was no more. The social order was upended as elves suddenly became an underclass in the very society their ancestors had built. They were not exterminated, but continued to live amongst the humans. The males have been barred from public office but live comfortably in the human world by dint of their substantial intellect.
Elven vixens are a different story. Bred by the males for beauty and submissiveness, the humans have taken them as slaves. As I have told you, the law requires that every vixen be leashed, collared, and plugged at all times. This is utterly desirable and necessary.
This is the part where I inform you that vixens are heckin' adorable. They love to chat with their elven girlfriends and are comfortable sharing their deepest feelings with their masters. But anyone else? You'd be lucky to get three words out of them. They're extremely feminine, notoriously vain, and paradoxically stoic. They're intensely emotional in private, yet convincingly aloof in public. If humiliated, they usually feign indifference, even when everyone can see them blushing. It's only in private that they're willing to shamelessly beg for the cock they constantly crave.
They come in varieties called breeds, which have names like Summer Breeze and Strawberry Shortcake. Each one has its own aesthetic and personality. You want a petite little ball of energy with angelic blonde hair and tight breasts? Electric Rose is what you're looking for. You want a tall and busty girl who is shy and easily humiliated? Try Chestnut Wonderland. It kinda goes on like that.
