May takes a look at the mirror

After settling down and opening their suitcases, Mia decided to shower first, leaving May alone for a few minutes. Her dead phone was still charging, so she decided she'd change into night clothes and look around the room. Pulling out her cotton pajamas, she spotted the mirror by the bed. She laid the clothes down on the bed and tied up her long black hair.

Then she stripped off her day clothes and bra and looked at herself in the mirror. She was thin, with a relatively unimpressive figure. Her modest B cup breasts paired well with the slight curves of her hip and cute butt. Boys tended to pass right over her in favor of her more gifted sister. Because of that and her timidity, she was very inexperienced with boys.

A strange feeling came over her and she decided to slip off her pink panties too. Maybe she just wanted to look at all of herself. Maybe she was looking for something in particular. Either way, her full form was in front of the mirror, and that's when it started to change. The mirror started to shimmer with a strange outerworldly energy, her figure disappearing from the glass. When it reformed, May gasped. It was still her, looking back at herself, but something was definitely different now.
