I must say that I was ever so slightly intimidated by what appeared to be a very long read in block form as it was, but I very much enjoyed this story. Different world, different customs, but fortunately still skirts and blouses to tantalize and tease with.
I like the concept of a punishment room, or even the equipment standing ready in a common room if needed, there to remind one with bad intentions to behave. I also like the concept of indentured servant status to serve out a light prison term, (this my definition of a FULLY furnished apartment in a kinky world far from home), and I could see your main character Linda committing some minor crime or social offense with her unfamiliarity with her new temporary home and landing afoul of the law there. This could happen either accidentally, or otherwise, she being far from home herself and wanting to try something new on this business trip, or her new boss Tom potentially having to purchase her out of trouble in the former case.
Could Linda then become the property of Tom for their extended business trip, or even beyond if she failed to perform, she being marooned on planet when he finally left and sold off to the next executive to keep his activities with her secret? I could see this as a version of "What happens on Hasbold stays on Hasbold" one way or the other.
Linda seemed to like the show she had been forced to watch at some level, and I might be reading more into this than what you intended, but I don't think she desires to be the one holding the whip. If of course I'm wrong though, could Linda find herself in trouble with the authorities for trying to stop this barbaric practice, she then ironically experiencing it first hand by court order rather that just watching vicariously?
Thank you for a fun read, and please don't take my suggestions for a potential sequel as anything but praise for a story that I might have liked to write myself, Jackie.
