I've been trying hypnosis for a while, and haven't had much sucess, but this little file really did it for me. Perhaps it's because it's a simple file that doesn't attempt to cause any permentant changes, or install long lasting triggers. By the time I woke up, I was shaking with lust, and couldn't help but spack off there and then.
It's a highly enjoyable file, which seemed to work really well on a beginner like me.
