Although Ty hadn't mentioned any specifics of his transformation into the car she was now driving, from past experience she knew that he would have arranged to enjoy being driven. They actually had quite a bit of time before the show, so she decided to take a scenic route to the theater, rather than the most direct route. She expected that he'd want to experience a variety of driving conditions, so after spending some time on surface streets, she got on the freeway. She was normally a very conservative driver, but she was sure he'd enjoy it if she drove a little more agressively. She didn't do anything dangerous, but she did try to have some fun.
As the time neared, she drove to the theater, and parked. Shortly after she shut off the ignition, Ty's human body appeared in the front passenger seat. "You're the copy you said you would make?"
"That's right," said Ty.
"How did you like it?" Lisa asked.
"It was awesome!", Ty replied. "Surface streets were nice, but when you got on the freeway and revved me up more, well, it really did rev me up more. I'm definitely going to want to do this again."
"Well, you'll get to do that in just two hours, but for now, let's go watch the movie. Oh, and by the way, where are the keys?"
"In your pocket," Ty said.
Lisa checked her jeans pocket, and sure enough, there was a key fob. They got out of Ty, and she pressed the lock button on the fob. Ty beeped. Lisa and Ty walked into the theater. Ty bought the tickets, and popcorn and beverages, and they found seats. He put his arm around Lisa, and she enjoyed the film, though he was distracted by his desire to merge back into his car form, and be driven around more.
When the movie was over, and they left the theater, Ty asked, "How do you like the Z4? Would you prefer that I be some other car?"
"No," Lisa said, "the Z4 is a great choice. I've never been in one before."
"I hadn't either," said Ty, "and I still haven't ridden in or driven one. I've only _been_ one!"
"You could wait and merge when we get home," Lisa suggested. "You can even drive, if you like."
"No, thank you," Ty said. "Maybe some other time, but I very specifically want to be driven by you." After she unlocked Ty with the fob, and they got in, Ty's human body vanished.
On the way home, time was even less of a concern, so Lisa took an even more circuitous path, There was a hilly area that was a few miles out of the way, but she thought Ty might enjoy being driven there. Eventually she got back home, parked him in the garage, and closed the garage door. Z4 Ty disappeared, and human Ty reappeared. "Thank you!" he said. "That was wonderful. Are you ready for some more fun?"
Apparently being driven as a car made Ty horny. "Give me a minute," Lisa said, "I have to move Maria's car back into the garage. I'll meet you in the bedroom." Ty went on up to Lisa's bedroom, and shortly thereafter, Lisa joined him.
"Just how much pleasure did you get out of that?" Lisa asked, curious.
"Well, the entire time I was running, I experienced a fair bit of pleasure. But there were higher peaks when you accelerated harder, like merging into the freeway. When you shut off my ignition at the theater, after I duplicated myself, I went to sleep, and slept pretty soundly until you unlocked me again after the movie."
"Did you have any orgasms?" Lisa asked.
"No, but I planned it that way," Ty said. "I wasn't sure what would happen if I had an orgasm in car form while you were driving. I was afraid it might cause a problem, so I deliberately set up the transformation to avoid that."
"That's a shame," said Lisa, "but I very much appreciate your safety concern. Maybe we can figure out a way to let you try that, somewhere where there's a big open space and no traffic. Maybe the parking area for the place where they have the ren faire, when they're not actually doing that."
"That sounds like a great idea," Ty said, "but I'm fine with doing without as a car, so we can do something else and share them after. Like right now. What forms do you want us to take? I'm up for anything."
"So am I, but whatever we do, one of me is going to be an aquarium waterbed again." They went through the portal door to Ty's bedroom, since he had reinforced his floor and bed frame for the weight. Lisa duplicated herself and transformed at the same time. "I'm getting better at doing the duplication and transformation simultaneously," she said. "When I made a duplicate and transformed that self into your cock, in the school cafeteria, that was the first time I did it. If you don't mind, before we start, I want to experiment a bit with a few other things I think I can do, using transformations you've done to me before, but in different sequences and combinations."
"Oooh, sounds exciting!" Ty said. "Show me what you've got!"
