Intro. The Rosario are robots designed to keep humans in line and make sure that humans never overthrow thier robot overlords. Every human from the age of twelve up is forced to be owned by a Rosario even if they don't want one, the Rosario keeps humans in line via anal pounding, the intensity of the pounding and wether or not lube is used depends on the humans behaviour. The Rosario don't only pound thier humans asses for punishment but also as a reminder that they own the human completely and that the human has no autonomy. A Rosario can pound thier humans asses for fun and can decide what counts as bad behaviour in thier human so they can punish them for even just blinking if they want to
