Arousal Inducing Audio (mind control, female-female sex, masturbation) by Synaptic Virus
Two girls experiment with sexy subliminals. Not realizing the messages are designed to slowly turn them lesbian.
Subliminals and hypnosis can’t really change someone’s sexuality. However, there’s every possibility that the two girls already had unknowingly harbored attraction toward each other, and that thought makes this hotter for me. This was addressed in the story somewhat abstractly, which added a good degree of realism at the end. Definitely built for those that find hypnosis super hot, while I found it more amusing at first. But yeah, I eventually found it pretty hot, too, once it got going. Mutual masturbation can be quite hot! This was a fun read.
