btw I would like to know most effective breaking method
I not sure what I been doing is good or not. It take like 50 week to have my milked slave to finally become devote. she been on accepting for looong time while other I either give up and bought replacement or train through
didnt use cellblock at all
pregmod
From my paternalist perspective:
Several "greeting" options grant obedience, or fear for high-resistance slaves. Particularly "address health issues" (only if bad health), "chance to impress" (only at accepting+), dominate his dick/show a real erection (only if the slave or you both have a dick). If none of those are available, spanking can give a bit of obedience if they're at least ambivalent or so, for a bit of extra obedience/fear (+obed if ambivalent(?) or above, +fear otherwise).
If they're resistant and not scared enough, send to cellblock. Note you don't have to get them all the way to terrified, just frightened is okay and won't take as much time bouncing back from.
After that/otherwise send to school.
Below accepting, give restricted living, relationship and speech rules. A harsh outfit (nude is safest, ropes may cause masochism, straps don't work on terrified), gag, mask/cat ears, super corset if any. Chastity punishment, orgasm reward, smart vibe set to all sex (the latter two to compensate libido loss from the former).
If they're still not accepting after school, probably best to give PA.
When accepting, give normal rules and clothes, and send to work. Send to spa if they're terrified and you don't want that, but I don't think it's that important.
