Mei, a time traveller from the future

Mei was excited as she entered the time machine. She was going to the 1980s, the neon decade that gave the world shoulder pads, leg warmers, and scrunchies. She brushed a hair off her bare left breast. The future had nanobots that kept everyone warm and clean, so women like her were always fashionably nude. The past was a different time, but that's what the invisibility field was for. It would keep her safe from the cavemen of the 1980s.

She materialized nude and invisible by a college dorm in a small 1980s college town. She was here for a week, and then the time portal would open to take her back.

Guys were walking past as she watched from behind a hedge. The showing of Weird Science at the local movie theatre had just let out. Once the crowd thinned out, she stepped out to follow the last guy for anthropological reasons. He surprised her by coming to a sudden stop, his eyes bulging wide.

She waved, and he waved back, so she introduced herself. "Hi, I'm Mei! Can you see me?"

"Yes! Wow! I'm Gary," Gary said, thinking about how his every fantasy was coming true.

"I'm a time traveller from the nude paradise of 2080 here to visit your time. I'm supposed to be invisible, but you seem to see me. Can you hide me while I figure this out?" Mei asked innocently.

"Hide, as in at my place? Yeah!?" Gary asked. He was having trouble maintaining eye contact. His eyes darted between Mei's breasts and pussy.

"Yes, that would be wonderful!" Mei, clapped, hugged Gary, and kissed him on the cheek as she would in the 2080s, jiggling.

Gary and Mei set off for his college room. He tried to offer his jacket but she refused, insisting she was warm enough and didn't need clothes like primitive 1980s girls.
