I can find few problems in your slave, why she pride is aloof instead of unashamed? there's a tier 5 shaming punishment that lower a lot the pride and also give you one spark. You get better result in sex when pride is lower. Also spoil is a pain because when is bigger that one, drain all the good stats. Also increase if you don't give according punishment. ( I highly recommend punishing, because the penalty for not doing it is quite severe.) Few more things: mood is crucial for performance any task, keep it as high as you can. Also does she wear corset and high boots? iirc give +6 to sex. Use put in her place every day if she is spoiled. Guilty complex is normally a good thing, since high tier punishment give more awareness iirc.
