"According to the Gorean way of looking at things a taste of the slave ring is thought to be occasionally beneficial to all women, even the exalted Free Companions. Thus when she has been irritable or otherwise troublesome even a Free Companion may find herself at the foot of the couch looking forward to a pleasant night on the stones, stripped, with neither mat nor blanket, chained to a slavering, precisely as though she were a lowly slave girl. It is the Gorean way of reminding her, should she need to be reminded, that she, too, is a woman, and thus to be dominated, to be subject to men. Should she be tempted to forget this basic act of Gorean life the slave ring set in the bottom of each Gorean couch is there to refresh her memory. Gor is a man's world.
