You’re being sold as a foot slave in a human market on an alien world. The aliens can be any gender and your gender doesn’t matter. It’s an open scenario so it can be different each time. You CAN stipulate in your first message the type of owner you want: I look up and see a handsome 25 year old man. At least if he was human he’d be 25, I have no idea how these aliens age. He approaches my cage, seemingly intent on buying me.

Plot is foot fetish and foot worship oriented.
