Make some changes!

"You're beautiful as you are," you begin to make yourself feel a little better, since asking someone to change themselves just for you feels like a dick thing to say to a person, "but if you're offering to change into exactly what I want, I certainly won't pass that up."

Her eyes narrow at you as a sly smile graces her lips. She lays her hands on her shoulders, arms crossed on her chest, and says in a honey-sweet voice, "Just imagine what you want, Master, and I will become it."

You close your eyes and picture her in your head. Dark hair, bobbed just above her shoulders. Deep blue eyes. Seductive lips. Big breasts, smaller than she has now but still quite substantial, natural but firm, peaked with small pink nipples. Wide hips with a round, firm ass. Legs and pussy waxed smooth. Tight stomach. You even concoct a new outfit for her, a dress not terribly unlike the one she has now, only black, and rather than a zipper, the front is held together with string, parted down past her navel and straining to contain her bust, showing off impressive cleavage.

You open your eyes. To your amazement, Genie has changed exactly as you envisioned! "I take it this form pleases you?" she asks. The nurse leaves the room as Genie notices a mirror on the back of the door. She prances over to it and looks at herself. "An excellent selection indeed! My Master has a thing for pale women in dark colors, I see..."

Another nurse opens the door. Genie steps nimbly out of the way as she enters, a different nurse than the one you "improved" earlier. "You have a visitor, sir," she says.
