Any idea how to increase Obedience? Sorry if this has been asked before.
There might be other factors that influence it like location, game progression, method, strength of orgasm, etc, I'm not sure. For reference this is all done at level 100 with no edging on corridor using toys. There's also no difference with the number of orgasms. You'll get the same result whether it's one or five:
Ending the day without an orgasm is -10.
An orgasm in trance mode gives +3.
An orgasm in paralysis mode gives +15.
An orgasm in modify mode gives -14.
An orgasm in bitch mode gives -4.
Don't bother combining modes to raise/lower more. An orgasm in trance and paralysis in the same day is a change of +12, so it's actually lower than if you just did a paralysis orgasm.
Basically to grind increase put her in paralysis, orgasm once, and end the day. To grind decrease just start and immediately end the day. It's faster than giving her an orgasm in modify mode.
