This hypnosis file creates an interest in sucking cock that slowly evolves into an obsession.  It may start with an interest in stories or videos but it will evolve into a desire to suck cock, to master the skill of cocksucking to the point that anyone you suck will be blown away by your skills.  The file does not take your gender or sexual preferences into account, it simply curses you to become a Master Cocksucker no matter what your sexual preference is.
