It was an interesting experience, though it didn't really add much pleasure or fun for me. It felt kind of like an exercise tease to me.
As for feedback, I had two issues:
1) Reaching the first edge in the advanced training was impossible for me in one go. There was way too little stimulation beforehand to get me to edge.
2) When the cum order came, the beat stopped. Since all the previous times the beat stopped breathing was allowed again, I instinctively breathed without reading the text first. Just goes to show how quickly expectations can be generated and how little you think when out of breath.
