Lilith and Yuki were invited to try out a new experimental product princess pamps before they hit the market. Though with it still being in testing there may be some unintended hypnotic side effects.
As the girls were becoming under the effects of the hypnosis they couldn't help but help one another in the thick diapers. Giggling and laughing as they did with blushes on their cheeks.
With the hypnotic effect clouding their minds, they smiled and hugged each other tightly in their cute thick diapers.
