A boot on the van's tires

There was a boot on the van's tires, and a parking ticket on the windshield.

"Oh no, I guess I didn't pay for parking!" Stan exclaimed.

Mei went up to the van and bent at the waist, thrusting out her perky bare butt at Stan and Gary. She examined the device locking the van's tire, and then reached out with her finger. The nanobots flowed into the tire and then the boot snapped open.

"Wow Mei, you're a lifesaver!"

Mei giggled and got into the van with the guys.

"I think I have a Life Drawing class followed by Drama this afternoon," Stan said.

"I have Anatomy followed by Physics Lab," Gary added. "Do you want to go with me or Stan?

The van pulled into the college parking lot by the cafeteria and the library.
