Alter her to suit your needs.

“There’s one more thing I want to do before we must rejoin the real world, darling.” you say. “I’m going to evolve you a bit. Not as much as I’ve been, but enough that you will be able to serve me well for years to come.” She passes out as your power flows through her, altering her D.N.A. ever so slightly, extending her lifespan and giving her vast recuperative and regenerative abilities. Her eyes flutter open as she begins to recover. “Now get dressed, but leave the undergarments.”you say. “The bra won’t fit you anymore, and the panties are too soaked for you to be comfortable. You’ll have to buy some new underwear later.”

“Yes, my beloved Master.” she coos , kissing you as she moves to obey. You sense Mr. Andersen approaching, and dress quickly, pocketing the underwear and willing the smells of lovemaking up through the vent. You gesture for Kim to sit down as you telekinetically unlock the door and slip her your cell phone number and pager number. Just then Mr. Andersen gives his distinctive knock just as you and Kim are arranging yourselves.
