I've been trying various different files for months now, and I finding found some success. I spliced together a few files; the Train Susceptable(first file to ever put me under), followed by two repetitions of a Deepener file I found on WMM, finishing up with the Cum Torture file. I spliced out and edited it all so it ran together smoothly, and I was put under during the first file and awoke at the end of the Cum Torture file.
For those unfamiliar with the file, it wakes you up, unable to move, while you're slowly brought to three power orgasms. While I didn't actually cum, I found that when I woke up I was completely unable to move while I felt an intense pleasure building me up and holding me at the brink of orgasm. I was there for about ten minutes before the feeling started to fade and I could finally move again.
So while it's not a complete success, it's definitely a step in the right direction.
