A tall lanky man enters wearing a really short terrycloth robe, and apparently nothing else.
"Yes, lover boy?" Neil said kissing your father on the lips.
"Wha-?" you start to say, but suddenly you feel a sharp pain in your gut, and double over.
"Whoa!" gasped Neil, "Redecorating your kid's room into a garage?" he asked.
You look up. You're still covered with a sheet, but you're sitting on bare concrete. Your bed has vanished. Your bedroom window is now a roll-up garage door, and your ceiling fan is morphing into a garage door opener. You try to open your mouth but your teeth are cold metal and are fused together.
"Is that supposed to be happening, Daddy?" Neil asked your father.
"Ddddee!" you scream through your expanding grill.
"Yes, Neil, Teddy's being punished for his recklessness. He was supposed to return my Mercedes for you to drive today. He may not like that his step-father is a man only a few years older than him, but he's got to learn responsibility. So until I get the car back that he lost, he's all yours, baby," Joe says handing Neil a black Mercedes Benz key on a big silver key ring spelling the word "SON".
You are now on your belly, and your hands have turned into globs of black rubber. Tires?
You are in agony, as your bones become steel, and your flesh becomes rubber tubes, wiring, wood, cloth and leather upholstery.
"Oh, it looks like that hurts," Neil says pointing at you.
"I hope so," Joe replied, "He needs to learn a lesson. I expect the cops will have the car back in a day or two, but until then he's yours to do with as you please. Try not lose him!" he laughs.
"How d'ya lose a car?" Neil says shaking his head.
At last the pain stops. Your room is a garage, and you are a car. You feel a hand on your handle? It's sort of like a handshake, but it's not. Maybe a squeeze of your biceps? You are trying to relate your old anatomy to your new vehicular specs, and they're not quite analogous. Neil is opening your driver's side door, and planting his bare ass on your leather seat. Your dad's gay boy toy really wasn't wearing anything under that tiny robe. You feel his sweaty balls on you, and his half hard cock. He reaches up to the visor and pushes a button. Your former ceiling fan begins to hum, and your former window starts to roll up. There's a driveway leading out of your room now.
"I'll just take him for a spin around the neighborhood?" Neil asks.
"Sure, have fun. But if you're going into town, put some clothes on. I have some work to do in my study, but I'll be free for lunch, if you want to drive me into town to eat at Chez Felix."
"It's a date. And that's, daddy," he leans out of the window and kisses your father. Then he revs your engine. Adjusts his seat, and drives out of the garage. He is racing down the long drive, and you realize as he shifts between gears that your cock is now the shifter. Oh, fuck, your father's boytoy is giving you a hand job and he doesn't even know it.
He drives around the secluded neighborhood streets and pulls up in front a high wall. No one's about.
"About that car you lost, Teddy," he begins, "The police called to say it had been parked next to a hydrant and impounded. But I think it will slip my mind for a while, because it's so fun driving you." You feel a wet drop on your seat cushion. The dude must be hard at your humiliation, and is leaking pre-cum. You suddenly have a horrible idea about what your father and his boy toy might do in you.
He pushes his bare right foot down on your brake pedal and his left foot on the clutch, and he shifts your cock down to first gear as he climbs the hill back to your father's house.
