This is my narrative and relevant references from the Books where I discuss what one slave girl calls another.
I make no pronouncements on these matters, but report them as I find them.
Arrive at your own conclusions.
I wish you well,
I had a question on this topic some time ago, the topic came up again in "Have A Question?" and it has also been a topic in places like Second Life and even Real Life.
What does one slave girl call another?
I used the word sister to search the whole series. And I really did expect to find many instances where this word is used by one girl to address another. But I was surprised to find . . . that just is not the case.
Numerous girls, many, many times, in referring to other slaves, used terms such as kennel sister, chain sisters, sister slaves, pole sisters, coffle sister, collar sisters and sisters in bondage.
But the use of "Sister" is simply not prevalent (in fact, almost nonexistent).
However, finally, in book 34, I found this quote:
My analysis of the overall theme of the books is that, even though the word sister is rarely used in a quoted sentence, using the term to address another girl would be acceptable.
In other cases, girls referred to each other by name. Here is one example:
Other times the term Slave was used, as in these examples:
And another term is the word Slut, as shown here:
Here are supporting references where the word Sister is used in context:
I suddenly realized, climbing the ramps of Laura toward the compound, leashed, under guard, carrying a jar of wine on my head, balancing it with my right hand, among my sisters in bondage, breathing the fantastic air of Gor, that I was happy.
"I, and my five sisters in bondage, serve twenty men."
"Are they easy to please?" asked Arlene.
"No," said Constance.
"Do you think me any the less conquered than Janice and Alice, my white sisters in bondage?" she asked.
"Extinguish the lamps, my lovely sisters in bondage," said Aynur, pleasantly.
"We are all sisters," she said. "I am no more than they."
"You have pronounced yourself a slave," said Mahpiyasapa, wonderingly.
"Yes, Master," she said.
"Now," said Mahpiyasapa, "you are a slave, even if you were not before."
"And you are low girl here," he said, "so you will address your chain sisters as 'Mistress' as well."
"Yes, Master!" I cried.
"No," laughed Corinna, "I am Gorean, and many of my Gorean collar sisters would look down on me for even speaking to an Earth-girl slave. The name 'Corinna' was put on me that I might see myself as no better than the lowliest of slaves. Too, I think my noble master, Peisistratus, finds the name sexually stimulating on a Gorean girl."
I frankly see no reason to believe that the women of Earth, in general, are either better looking or not when compared with their Gorean sisters, nor, of course, that they are better or worse than we.
"Allison," said Astrinax, "suppose that one of your sister slaves, in the kitchen, had been given a candy, perhaps as a tip from a customer, from waiting on the tables."
"Thank you, Master," she breathes, licking and kissing the hand which has deigned to bestow so precious a gift upon her. How proud she is then, the possessor of so rare a treat, and how envied she will be amongst her chain sisters!
Too, such garmenture is unflattering, and likely to solicit ridicule from one's sister slaves.
My hopes of acquiring a suitable master had been muchly dashed after the burning of the gambling house, and my translation, with that of my chain sisters, to the Tarsk Market.
Had they thought to sway a Gorean male? Had they no sense of the discipline under which their chain sister had been placed?
"Would you not like, kajira," said Trachinos, "to have a pretty anklet? You might then be the envy of your sister slaves."
More often I was given a harsh scolding before the other girls, concluded with a stroke or two of the switch. The point of this was more to demean and humiliate me before my sister slaves than really hurt me.
I knew that Chloe was not happy that our first girl should be a barbarian. Indeed, I had gathered, from remarks by our Gorean chain sisters in the quarters, that such an appointment was rare.
Even I was uncomfortable, though my slave fires had not yet begun to rage in the manner of several of my chain sisters.
"Only a self-centered, simple, shallow, naive little brute," he said, "a trivial, selfish little beast, of inferior character, who would steal a candy from a sister slave, if it might be done with impunity."
Her vaunted declaration, however, had brought her only derision and mockery from her chain sisters.
How lost she was amongst us, so isolated and alone, reduced from her former status, and despised by her sister slaves.
There was laughter from several of the other cages, and I gathered that the girl from Asperiche was not popular with her chain sisters.
"Be still," said a coffle sister.
She was still reserved with me, and regarded me with condescension, but would no longer strike me, or speak to me as she had originally, perhaps if only because doing so would offer her chain sisters an excellent, and welcome, pretext for administering, given the recent past, another unpleasant lesson in civility.
How terrified had been several of my chain sisters even to think of being embarked on such a vessel.
"I trust I will be permitted a tunic," I said.
"It is not likely," he said.
"Then I would be humiliated before my sister slaves," I said.
For example, two of my friends, sister slaves, kennel sisters, Relia and Janina, I thought were quite beautiful.
Surely, I thought, her gowning would be likely to produce contempt and amusement amongst her kennel sisters, if not actual envy and hostility.
Several of her kennel sisters laughed.
Such things, doubtless, would make her resented amongst her chain sisters, but, too, they would not seem to me indications of madness, and certainly not, if there were any ground for possible airs or pretensions.
She struggled but was helpless in the hands of her chain sisters, two of whom maintained their grip on her arms, one on each side.
And now, I thought will certain slaves regale their sisters in the pens with accounts of their value, how they were bartered for a measure or two of rice?
"You sought to achieve an advantage over your sister slaves," I said, "who must display themselves as commanded, uniformly."
"Why are not men, male slaves, or beasts, bosk or tharlarion, used to turn the mill?" I had asked one of my chain sisters.
I thrust then, again, with a rattle of chains, harder, against the pole.
My pole sisters laughed.
"Mistress!" cried the girl to my left, alarmed. "The barbarian is ill, she is stricken, she has fainted!" Instantly my chain sisters stopped turning the mill.
"How brave she is," marveled one of my chain sisters.
I saw that the kitchen master, and my sister slaves, even Fina, understood no more of this than I.
. . . Why are you not, amongst the porticoes and colonnades, chatting and gossiping with your collar sisters, seeking news, a word dropped in the tiers of the Central Cylinder becoming common knowledge by nightfall, not comparing collars and masters, not complaining about the recent quality of the tunic cloth, not whispering delightedly of the intrigues and doings of free women, and so on."
The slaves are at the disposal of the men, as one would expect, but I, as a private slave, a status envied by my collar-sisters, was reserved to my master.
"You are a barbarian," she sobbed.
"So I am a thousand times less than you," I said, "but we are sister slaves. Do you think the collar is on your neck less than mine?"
Interestingly, I feared not only the views of the free, but those of my sister slaves.
Surely several of my sister slaves were more attractive than I, though, to be sure, much depends on the interests and tastes of a given master. I was even a barbarian.
"What a fool she is," said one of my sister slaves.
To my amazement my two sister slaves were freed of their chains in the hold and brought to the deck.
I, as were my chain sisters, was now in a brief, wrap-about yellow tunic.
"Yes, Master," I said, "I know." I was pleased that I knew this, at least, for I was acutely conscious of my ignorance of thousands of things Gorean. I was often derided by my chain-sisters, if I may use the term, for my ignorance.
