I have a lactation fetish. I want my girlfriend to produce milk but i don't want to inpregnate her just yet.
I want the effects of psychological pregnancy without her actually thinking she is pregnant.
What magickal tools do you recommend?
(I have access to her period blood to use on rituals.)
Trance induction + suggestion.
You'd also be benefited by constructing a thoughtform for it and having a spirit servant to help oversee the operation and which you consult as to how to do the whole thing.
Key to inducing trance btw; a state of heightened emotions (loosh).
So basically you have the power to control your gf but you don't want to exercise that same power on yourself ridding you of a goddamn fetish?
Really?
Alternatively you can focus on her pituitary and make her secrete prolactin. I mean shitloads of it, during pregnancy about 85% of the pituitary becomes a prolactin secretor.
