Submission is a way of life for the sex slaves of Mars. They must execute even the most degrading sex acts asked by their clients.
The male sex slaves of Mars cannot refuse to service clients. They must ride the fattest dicks and suck the nastiest pricks, or die.
The slave boys are disposable little bitches who fuck and fuck until they break. Asphyxiation by cock sucking is a common cause of death.
The slave maids are rented to clients for various group sex activities on a weekly basis. The customers prefer their bitches in dresses.
