I'd take over the local Femboy Hooters in my town and turn it into an underground femboy brothel.
Femboys are hired through a Bluesky application form and provided with a living space with many dildos, terabytes of sissy hypno porn and gooning compilations, lots of lube and poppers and a local Discord server for all the femboys. They are not allowed contact with the outside world, encouraging them to befriend and have bonding goonsessions with other femboys.
Every day they are fed with a specially curated diet to keep them slim, and their HRT is accounted for. No SRS or facial surgeries though, this establishment is only for femboys and not trannies.
Femboys also have to perform their special exercise regimen every day. They do so in skimpy clothes and in the lobby where any client can ogle at them.
If a femboy doesn't obey his orders or skips their exercises, they are punished by wearing a chastity cage and having their sex toys taken away. Then they are tied to a "punished femboy" booth in the lobby, where any man can tease the femboy and watch them whimper. The punished femboy is not gagged and their chastity cage is unlocked after being fucked by 10 men, so the brothel is usually accompanied with moans and frantic begging to fuck them.
You can pay to have sex with a femboy in a private room. Anything is allowed other than excessive violence. You pay on a per-10-minutes basis, so the femboy is encouraged to keep you on the edge and drain you as long as possible.
Each sexual act can be recorded with the client's consent and published as a part of the advertisement campaign. Every six months each femboy also has to record a video of themselves demonstrating all of their important bits, including their bussy, HRTitties, feet, how many inches they can take in their bussy and their mouth, handjob/blowjob demonstration, their girlcock and the amount of ejaculation they produce. These videos are recorded with one of the owners of the establishment, who is masked for anonymity.
The femboys are freed from the brothel after their 25th birthday. Their goodbye party is held where any man can indulge any of their fetishes for the entire day for free. Any videos of the femboys are kept in the archive for blackmail. If a femboy gets HIV or suffers lethal injuries, they are quietly kicked out.
