Idea 1:

Ok so it's kind, sort of been established in the fandom for some reason that the male to female ration in Equestria is like 8 females for every 1 male or something like that.

Anyway what if the reason for this was because there was a secret law that no one talked about but obediently followed with out question that stated that any colt who is an only child or hasn't gotten his Cutie Mark by a certain age is to be feminized into a filly? And what would happen if Pipsqueak failed to meet the requirements need to stay a colt?

Idea 2:

Pipsqueak asks to join The Cutie Mark Crusaders not realizing it's a girls only club, and they let him join under the condition he helps them try to get their Cutie Marks in Forced Feminization!

I would write them myself but I can't write clop for shit.
