Office worker by day, slave by night (M seeking F, D/s)

[Top Cat]

She's a hard-working office worker. Always gets to work on time, works hard, gets her work done. She goes home feeling satisfied with a good day's work. But something happens after sunset. She leaves her comfortable home, travels across town, and submits herself for a night of debauchery. She does anything, everything her Master demands of her. And then, once things are done, she goes home to sleep, and starts again the next morning.

But... why is it this way? Is she being compelled, controlled somehow to do these things? Does she have a split personality? Does she even serve the same Master each night? Could her night start creeping into her day? All of these questions, and no doubt more, will shape the story we tell together.

PMs, please.
