Slave Maker 3 is fairly tame compared to Jack-o-nine-tails. As you may have noticed cmacleod is a bit of a moralfag, so there is no option to actually force slaves to do anything or rape them
with Ayane being a notable exception, gotta build up obedience to get them to willingly agree to do extreme sex.
And the requirements can be all over the place. Like, one girl has 0 obedience requirement to do anal sex, but needs something around 30-50 to go naked for a dayThis here wiki answers most questions about stats, technical details and all that other spergy stuff:

Skills can be gotten after a levelup following successful slave training (for the exact details, see wiki). Slave Trainer is kinda important since it allows higher max stats. A very skilled slave can rake in a fuckton of cash in jobs, and if you're freelance you can take all the moolah for yourself. If not, you gotta make money off sales, actually having your slave maker work or taking a cut of your slave's competition winnings (they have competitions every week, hyper much?)
And you can usually cook up a better slave maker using the character designer rather than taking a stock option.
