Between ages 16-20
I feel like foids should be locked and tied up and used as flashlights.
Beyond their vaginas (assholes for some), their useless.
Their holes are what give foids any value so we should get as much value as we can out of them by keeping them locked in rooms and guys entering to fuck them then leave.
Between 20-38:
The foids should be put on a breeding program where a guy pays and chooses a foid he wants to impregnate.
They raise a kid together and if she ditches/leaves them, they'll all be tagged so she's tracked and killed.
After 38, the foid should be killed as the child will be way over the age of 15 meaning he's strong enough to survive.
Any foid children born will be raised as normal, but by 14 they'll be given "sexual education" so that by 16, they may enter the sex world for 4 years.
