Arthur's fantasy - this is a different slant on the Carol cum Coral story.
Prologue:
On another world in our galaxy, the states have always been at war with their neighboring states. At one time the armies consisted only of men; however, after many generations of war, the male population has dwindled to a small percentage of the population. Now, women are the warriors and battle each other. This has been the result of a change of mood. The battles are less about feuding and land grabs and more about television entertainment for the masses.
This is now a matriarchal / mostly lesbian society, perhaps with too many women; therefore, the hostilities continue.
A few of the men left have been chosen for military service and go through training as company commanders. They are of officer rank and do not engage in the actual fighting. They are far too valuable as inseminators. The first few years of their service, they are in the rear echelons at headquarters learning newer battle plans for better television coverage. When they have been promoted from 2nd Lieutenant to 1st Lieutenant to Subaltern, they take the command of a new company of sixty female warriors: six units of ten women each.
When a Subaltern takes over a fighting company, he or she is given a consort, a young woman just graduated from a military academy. She becomes his/her confidante, military aide, advisor, liaison, etc; in other words, his/her good right hand. In addition to military matters, she has also been trained in all aspects of love and sex with either a male or female as she may be given to either. She considers herself her consort's property; therefore, she will consider her consort, her lord, above all else and conducts herself accordingly and appropriately.
As a liaison to higher military ranks, she is expected to service the superior's consort in whatever way that woman desires.
In addition to his military duties, the new Subaltern is expected to inseminate as many of his troops as possible. He will have them brought to him two at a time whenever he has enough strength left to service them. The Subaltern has been chosen specifically for this 'extracurricular' duty.
Arthur has spent many hours fantasizing about having sixty women, in addition to a personal consort, in his company at his beck and call. He daydreams about having them pleasure each other until they were highly aroused. Then he'd enter the fray, taking them back and forth until he was ready to sow his seed. Then he'd have them in a sixty-nine position and shift back and forth from vagina to mouth until he erupted. Unless he came in the bottom girl's mouth, the warrior girl on top would receive his largesse, the girl on the bottom of the sixty-nine would lick his penis clean and whatever was overflowing from the vagina of the girl above her. Sometimes he'd have her lick and suck all of his semen from the birth canal of the girl above her. He wouldn't want to impregnate all of his warriors every time they had sex. That would deplete the fighting ranks when they became pregnant, so he picked and chose which ones he'd leave inseminated to bear the next generation of warriors.
This is where Arthur's fantasy brings Carol into the picture. He will ask her to become his consort. Consort?
Carol will no doubt think of 'consort' as 'wife' raising her hopes of commitment. That is so Insidious on Arthur's part, but it's his attempt at pulling Carol into his scheme of having her go down on other women - while he watches and possibly joins in.
"Okay. I understand your fantasy, but what does it have to do with me?" asked Carol. "You've already convinced me that most men want threesomes, but I won't perform oral sex on another woman."
"Yes, I know you, Carol, won't, but what if you weren't Carol?'
"I have no idea what you mean, Arthur. I am Carol."
"Well let's say you were transformed into someone else who didn't have Carol's negative views on sex with another woman? In fact, you'd be someone who had been raised to want to have girl-girl sex.
"Remember the TV program we watched where the psychiatrist was helping her patient to overcome her deep depression. She had her change to another persona who was serene and angst-free. They would use certain buzzwords while imagining they morphed into an alter ego. It was a reversal of attempts to eliminate multiple personalities in one person. The success rate was high enough that she even wrote a book about it.
