Lumi is out shopping for some new clothes for the Summer season. She stops to daydream of some big girl underwear, but already leaks a little in her diaper. Without even noticing the accident, she goes on to pick some T-shirts that would match with her Summer skirts. While trying them on in a fitting booth, she leaks again, the wet spot in her diaper growing ever more visible. Only after the third accident she notices how wet and swollen her diaper is. Seems she can't hold her pee at all!
