Gary wanted to explore the Chronivac some more, but then he noticed some features like transferring the software to other things... Including his bus. A little bit of reality modification and his bus had a small monitor which held a few options for the bus like adjusting the fare, changing the bus itself, auto-driving, and changing anyone inside of the bus.
Enabling the auto-drive Gary started his route, and decided to test out some changes without reality changes or anyone else being aware of what was going on on himself. He felt himself get a little skinnier and shrink a bit in general as he de-aged himself to 21, and then felt himself bulk up as he added 2 feet to his height, He then felt weird as his dick shrank in and breasts formed on now her chest, and at that point Gary stopped messing with some of the easier commands from the chronivac. Well he regained his manhood, but he wasn't feeling like being a woman at this point.
Gary could however decide what type of bus he was going to be driving for now. There was his standard bus... or he could be a school bus, or a prison bus, or... he was pretty sure that most of the other buses weren't actual things but he wasn't going to argue with the menu to a device that could easily alter reality. He ended up deciding to run a ____ bus
