Picture this - when a female wants to transition to a male, if she's of certain age (the most fertile to be precise), say 18-30, she's sent to a fakeboy farm.
It's a corrective institution where "ftm" women are basically kept as living incubators, most first world countries struggle with declining birth rates after all. If you want to abandon your duty as a woman, you must first fulfill your natural role to its fullest before you can do it.
Such a fakeboy is taken to the farm where she's kept with other trans "men" in individual stalls placed next to each other in long halls, ass facing the wall, fully naked, and on all fours, a position in which she's always ready to be fucked. Each stall has a door at the back, leading directly do the outside, but not big enough for the person to escape.
Every day from 9 to 5, the doors are opened, giving free use of all the women to breed. Any man can come and fuck any girl he wants through the door for free, the only requirement is having been tested for STDs, we wouldn't want to lose any of the incubators to some silly disease. During that time, the halls are filled with a cacophony of feminine moans and whimpers. It's not uncommon for the farm staff who are responsible for feeding and cleaning to have fun with the fakeboys themselves, in fact, many guys apply for the job just because it gives them free access to the whole bodies of the girls, not only their cunts poking through the door.
Of course, each person gets pregnant, that's why they're here in the first place. Every woman is kept in the institution for, let's say, until 25 (the time the brain stops maturing, identity is fixed etc.). At the same time, everybody needs to "serve" for at least 3 years, so everyone past 22 is kept there for that amount of time, 22 and less need to wait for until they're 25. So, if an 18 year old gets into the farm, she's going to get birth to at least 6 babies minimum until she gets out. One pregnancy ends, another starts, pretty much all the girls are getting cummed in multiple times a day every day by many men. Since the babies are taken from their mothers very early (they need to resume their cumdumpster service as soon as possible, no time to raise kids), every woman has milking devices attached to her breasts, so that all the milk accumulated in them can be emptied somehow. Everybody takes gallons of cum during their stay at the farm, nobody knows the fathers of any of the babies because the rotation there is so big, who wouldn't take a chance at fucking a young pussy raw with no consequences?
By the end of their stay, each fakeboy is a completely different person, both physically and mentally. Their breasts enlarged and swollen from years of lactating and getting milked, their pussies loose from thousands of cock taken and babies birthed, and most importantly, their minds changed. If she still wants to transition, only then is she allowed to. However, after their service, most girls become cock-obsessed sexoholics and any thoughts about being a man leave them completely. Perhaps it's because of maternal instincts doing their work, or maybe the continuous fucking they go through for years is able to convince them of their position, their role, their nature. Most of the time, they become prostitutes, dedicating their life to continuing their service even further by pleasuring even more men.
