She likes them.

The bell went off and the class cleared for the day

Marinette went without her usual shirt and jeans in favor of a sundress of her own design. It was bright pink with red trimming and patterns sewn into the skirt that evoked the Paris skyline. It was something Marinette tok a lot of pride in. While everyone thought it was fashionable, Marinette had a secondary purpose in mind when she made it.

As she made her way out of the entrance of the school, Marinette made sure that he gait was as normal as possible. She didn't want people to suspect anything.

Underneath her skirt, she was not wearing any big girl underwear. Instead, she was wearing a diaper. It was big enough to fit her, but she had used it since lunch hour and kept her legs apart.

She didn't need diapers physically. She just liked to wear them. She liked wearing diapers and crawling around and acting like a baby. It was a dirty secret of hers and only a select few knew anything about it.

At least once a week she would indulge herself, and today was one of those days.
