"What do you want me to do when I finish cleaning the house, master?" Keith asked.
You yawned, "If you finish? Before I wake up? Go spiff up my car, slave."
You were have a wonderful dream, when you are awakened by a whirring sound, and hot wax being massaged into your chest. Keith is standing over you in the garage with a buffer- a car buffer, and he's polishing you with it.
What the (edit) Frack? you think with the audible "edit" strangely sounding like a robot phone caller.
"Oh, you're awake," Keith said eagerly, "I was just following your orders and spiffing your car up. I merged you with it, man and machine, let me turn your speakers on." Keith opened the driver's side door and sat down.
You feel strangely violated, like he just shoved himself down your throat or ass, but not that exactly. You feel his bare synthetic human skin press against your leather seats. Vaguely you wonder if they are human skin now.
"EDIT-" said the metallic voice, as Keith turned the radio on. Your voice comes out of the radio car speakers, "Darn it, Keith, what did you do to me?" You wonder why you aren't asking him to reverse it, but for some reason you're not.
"Well, sir, I finished cleaning the house. Then I accessed your memories to see what your ideal car would be. And I came across the Knight Rider's Kitt car."
"Good- EDIT- grief, you didn't?"
"Yes, sir you are now a most excellent human-automobile hybrid."
"How do I have sex now?" you say testily, you do like the power you feel being a muscle car, "Ooh!" you exclaim as you feel your penis shoot out of the driver's see to fuck Keith's ass. The seat rapidly reclines, and you discover that you really are a living car with quite a few moving parts. About 10 minutes later, your upholstery is all sweaty, and you're panting.
