Idea that came to me while listening the "Thunder" by imagine dragons
Post hypnotic suggestions;
-Seeing flashes of lightning brings you to the height pleasure and the edge of orgasm, without release until..
-hearing the thunder, makes you orgasm constantly for as long as you hear it
Best for women (Because multiple orgasms) who live in places with a lot of storms.
Could also work with videos of lightning and thunder
The evil idea is, if they see a lightning bolt flash in front of them, and hear no thunder.....
