A few provisos

"A few provisions, I think" you state, as you look the UPS girl over. "First, this is all you'll wear WHILE here," you purr as she nods frantically in desire. You lean in closer, taking hold of the ring on her collar, pulling her closer, and whisper to her. "and second, other than work, this is the only place that you WILL be."

She looks into your eyes, still glazed with lust but a little confused. "Wh-what do you mean?"

"Simple, if you want to serve me to use her, then that's what you'll do. You'll move here and serve me just as long as she does."

"But she'll be here serving you until the day you die?" Her voice trembles and you're not sure if it's in fear or hope.

"Precisely. And I expect the same from you."
