I always love the shota fetish, ever since I hit puberty early at age 8 and taboo desires for my own mother and other older women. Now it can all finally become a reality, and I made a series of wishes to lay the groundwork.
First I set the max age for all males to be age 15, and that they will never go past that number and will take twice the years to get to that age. Everyone under 15 will not be changed, but every male older than that will regress to a younger one. Males between 18-29 will regress to age 5-7, with the all males reaching age 5 will hit sexual puberty. Males between 30-39 will regress to ages 8-10. Males between 40-49 will regress to age 11-13, with males between 59-69 to regress to age 14-15. All males above the age 69 will regress to a randomize age between 4 to 15 years old.
Females will be largely unchanged by the new world, with a few minor changes. They will age like normal, but their pregnancies will only last 6 months instead of 9, and all girls reaching 6 years of age will get their first period. Incest will be encouraged, and babies born from it will have no birth defects. Every woman above the age of 18 will have D cup or higher breast sizes, and will always have milk in them even if they don't have any offspring yet.
After the last of the finishing touches, I wish for myself to be 8 years old again once the change happens, so that I could enjoy life as a shota at a young age and still be mature enough to make any future wishes. I made the final wish, and everything went black for a few seconds.
