I can't believe every book and movie with the plot of "ooh what if all men disappeared in a big flash, what would the women do?" keep forgetting about the existance of trans girls.
By (very) rough estimates, cis women globally outnumber trans women at a ratio of somewhere around 1000 to 1. Since trans women are the only ones with the neccesary equipment to reproduce, they would be in extreme demand, and thus, nearly every t-girl would be able to amass harems of 1000 cis girls each, give or take a few hundred.
The average pregnancy lasts for 268 days, so even if a transfemme is breeding ciscunts at a steady rate of 3 girls/day, there'd still always be more than enough fresh, fertile pussy for her to bust a nut in.
Obviously, every non-lesbian cuntgirl wishing to reproduce would effectively have to be straightbroken and molded into the perfect girlcock fuckslut if she'd wish for a chance to get a sacred creampie by her divine transfemme overlords.
Also, due to the scarcity of trans girls, they could pretty much have their cuntgirl concubines do whatever they'd like for them. You'd find some weeby t-girl with a harem where all cis girls are forced to dress up as anime characters and do cringe kawaii-voices, and another one where they all have to get super-sized implants to please their mistress.
One never allows them to wear clothes, another one likes to dress them up in fetish gear. One has a rule where there must be a pair of cisgirl lips around her cocks at all time she's not spending pumping cum into cunts, another denies her girls all forms of sexual release until it's time for their annual breeding, to really make them squirt around her fat cock.
One straight trans girl has even managed to force-masc her entire harem into soft little femboys, but their pregnant bellies betray their true gender.
Now tell me: why do we never see this part of an all-female society in media? After all, it's only the natural order of things.
