I always wonder if viro would handle a concept like fat prision, where it's a system where inmates are heavily incentives to follow the wardens orders which is eat the food and put on weight to get better treatment and freedom. Not following orders gives you terrible treatment and possible death from the punishments. It sounds like following orders has no consequences but in this scenario being fat has real world reprocussions where it leads to fatigue, heart failure, diabetes, and etc. All of which can lead to an early death. Warden can have a thing for fat people but also like the morbid concept that by the time a person gets extremely fat, USBBW, they're given enough freedom to essentially leave at their own will but are too fat or addicted to the food to do so, if they even live to that point. So what I am proposing is some thriller of a new inmate, probably female, on the clock to follow the rules of prison but try not fall into it's trap and be able to escape before her own body becomes her personal prison and executor.
