2. All (far as I can tell) newly captured slaves have a cap on their obedience. Give 'em a few days to a week and you'll get a notification that they've 'gotten used to their new servitude' or something similar. That's when you are allowed to get them to 100% obedience.
I treat all my slaves well. I never beat/dominate. I just scream at their faces when they start feeling a little rebellious. Aren't I nice? All my slaves love me. *screams at a slave that did absolutely nothing wrong but was feeling a little unhappy with the luxury I provided* Love ya~! xP
