There is some good stuff sprinkled in however the best stuff was early on, but nowadays the deluge of subpar content has created a feedback loop. Thus has begun a process that resembles enshittification but is really just bad taste amplified to the nth degree lol.

It's not a satisfying reason, but "because I like something other like minded people joined over time," is the reason.

I just don't get why people commission this when we so many other great doujins that get be voice acted

You get used to it, Kisou needs to work on their understanding of anatomy and perspective. Even if their using Ai to bridge the gap for coloring they should be using real world examples/picture and images to improve but I don't tend to see much experimentation in their work.

The voice actress doesn't have enough content, (5 pages here) for most people (me) to enjoy any part of it.
