I strongly, suggest not buying it from DLsite like I did. It required a special DRM viewer that I had to screen rip using a program I found in the forums. I'm not sure if this is the highest quality either.
Lesson learnt, pay attention if a product requires DRM on DLsite. I'm not buying any more of this artist work ever again.
In anycase, I love the story and hot interactions with these two, and I hate DRM. The End.
Edit: Made a torrent. Basically just zipped everything up.
