Actually,
Bull Power could be manipulated into working for that; you'd have to be regular about using the spiral and surrender to him milking you to
Macho Sub to make it work, though.
Directions: Trance regularly to Bull Power, especially the spiral / Brainwashing loop combination. Bull power will stop you from masturbating, it will also program you to be susceptible to milking as a form of brainwashing. After a while, have him milk you to Macho Sub. Orgasm will lock in submission without turning you bottom.
