Soothing and immersive. You have a good voice for this and the ambient music fits it like a glove! There's some time in the end for listeners to reflect on the whole thing with subtle background noises, I liked that.
I don't think I can call my own experience horny, but there's some kink to this for hypnosis fans.
Curious about the procedurally generated aspect you wanted to do, that sounds like quite a challenge since meditation audio tends to be very smooth and personal.
