Karyn rolled over in her sleep, causing Jon to take a second. Not only was Karyn naked, she had a cat's tail growing from the base of her spine and kitty ears on the top of her head. She now lacked normal human ears. Karyn was now a catgirl! And a particularly sexy one at that. She had been attractive before, but now her form had been altered to its nearly perfect ideal. Jon heard a moan from the other side of his bed. Crawling out from beneath the covers was none other than Sarah McMillian, who was also a catgirl! "Wake up sweetie," Sarah said to Karyn and reached over Jon to give her a tender shove. Karyn woke up, yawned and looked lovingly at Jon.
"What are you doing in my bed?" asked Jon.
"Having sex, master," said Karyn. Sarah giggled, and snuggled up with Karyn, who kissed Sarah and fondled one of her breasts. "Isn't that what concubines are for?"
"Master? Concubines?" asked Jon. "Why would I have concubines?"
"Because you bought us, master," said Sarah. "From the concubine market, remember? You agonized over the choice between us and wound up buying us both. I'm glad you did, 'cause I can't imagine our relationship without my little sweetie." Karyn blushed.
Jon was even more confused. Sarah nice? Both girls transformed into sexy catgirls eager to give him pleasure? Calling him master? Jon silently made a wish to find out what he had wished the night before. He discovered that he had wished that there was a race of catgirls that existed alongside humans and lived to serve them. Catgirls were naturally bisexual and were purchased by both men and women as concubines, and the process was socially accepted, even encouraged. Sex between human men and catgirls produced more catgirls. Most catgirl daughters produced by these unions were kept in the family, mostly to serve as concubines and servants, while others were sold to friends or family. Some families were served for generations by catgirls born from the same bloodline. Other catgirls, like Karyn and Sarah, were born on concubine markets to breeder catgirls impregnated by anonymous doners and sold to individuals who otherwise did not have access to catgirls of their own.
Jon pulled Karyn towards him and kissed her. Karyn giggled and her tail flipped back and forth in excitement. A pair of arms wrapped around him from behind as Sarah tried to get in on the action. "As long as I have a couple of sexy catgirl concubines," said Jon, "I might as well get my money's worth." Karyn opened her legs and Jon slid his throbbing manhood into her waiting cunt.
