I've a suggestion to make.
Id like to see more passive interactions between the slaves. I've seen the events where you intervene, but i'd like to have just random day to day of slave interaction. Like one day 2 slaves have sex on their own and get pregnant without you ever having to interact with them. Or if a slave is lactating, another slave could come and relieve them of the pressure without you having to either send them to the farm, or sucking them yourself. Job like fucktoy, but just for your own slaves to get relief. Would generate mana daily, and be less stressful than the fucktoy job itself due to being with your own slaves only.
So i guess what i'm asking is for a In Mansion job, same requirements as Headmaster, but it provides sexual release for all slaves in the mansion ( scales like cleaning does ) Bottom Bitch or something on those lines could be a name for it.
Also could make it that your slaves have free use of anyone in Jail on a daily basis too with the same outcome, but just builds fear and their preferences/permission doesn't matter because they are in jail.
