A Secret That Must Not Be Known EX3

Wives whose husbands are away on long business trips and who are sexually frustrated are relieving their pent-up desires by going for walks in diapers. Initially, it was just lifting their skirts to show their diapers, but it gradually escalated until they were practically naked, walking around the park while using vibrators for pleasure. Mothers who worry about their daughters' diaper play escalating have ultimately gone through the same thing themselves. In the end, Yui-chan ended up resembling her mother.

This concludes the "A Secret That Must Not Be Known" series, based on Delicious Party Precure.
