Alien Masters
Since their peaceful and very welcome arrival in the Gynarchy, the alien race have eked out a very nice living for themselves as slave masters, to the extent that nobody now blinks an eyelid at the sight of an alien standing over a public footslave with a whip.
The aliens make exceptionally good masters and mistresses as they are very clever and cruel, and are especially dexterous with the whip! Here we see one such alien couple enjoying the spectacle of their money-making footslave lickshining the female public’s feet, for a price. Many citizens of the Gynarchy, you see, are prepared to pay that little bit extra for an alien’s footslave to lickshine their dirty shoes or boots as they know that slave will have been well trained to a high standard by his extra-terrestrial masters.
Note how the aliens’ own feet have evolved to provide a large gap between their toes for a slave’s tongue to be inserted into – hence their somewhat unusually shaped footwear.
