Makes the listener need anal penetration in order to orgasm when masturbating, which will be more intensely pleasurable than usual. (Also instills a need to regularly listen to the file.) Progressive relaxation induction from EMG, and body of file based on EMG’s Curse Anal Slut with significant changes.

One reference to desires that includes (but doesn't require) cock, otherwise gender & orientation neutral—and script only, so easy to change. Written as a curse file, but I'm not posting a release; again, it's script only, so up to you to create the release.
