There's no reason to choose when she can have both.

Kelly scribbled another line. My car is a luxurious limousine.

Around her, the crummy second hand commuter car that smelled of stale plastic and long-ago fast food runs ran and shifted into a gleaming chariot of opulence. Climbing out of the driver seat, Kelly smiled and decided she'd see how far she could push the command that her servants spontaneously change to obey her commands.

"Drive me home and give me a blowjob at the same time. Do so safely."

The driver looked confused for a moment, and then began to shiver, warble, bubble against the firmament of reality. Where once was one, there were suddenly two. Two identical blonde statuesque beauties in chauffeur uniforms.

"Of course, Mistress, I'd be happy to," they said in perfect unison. A moment later Kelly realized they also blinked and breathed in unison. Her driver hadn't developed a twin; she was one person in two bodies.

One of the driver's bodies went up front, and the other showed Kelly into the passenger compartment in the back. As they pulled out of the parking lot into traffic, her driver adjusted the rearview mirror so she could look back and watch herself unzip her mistress's pants. With a wink, she stretched her mouth wide and took in the still-implausible girth of her goddess.

"Don't make me come until I tell you to," said Kelly, deciding she'd ignore the ministrations of her devoted servant for as long as she could. Her driver moaned agreement and moved to begin gently licking and sucking on Kelly's balls. Kelly opened her blue notebook again and puzzled on another change to make to the world.
