I have the distinct suspicion that this sissy caption-maker is secretly a trans woman trying to crack eggs in the sissy community: https://www.tumblr.com/georginared
Pretty much all the captions are gender-affirming positive messages framed like they should be force femme but strangely aren't. Like, most have a message on the order of "Feel good about your feminine body! Wear female clothes you like to wear! Release the woman within!" A number of them reference a girl in the mirror, representing the girl you want to be, which is a common transfemme way of expressing a hidden feminine gender identity as an alternate self. Even one that you'd think would be about male domination comes down to "Find a supportive boyfriend". They're wholesome trans-positive messages and are framed like they shouldn't be.
