This is the frontspiece of an "ero audio" file, where the plantgirl instructs you in slow breathing techniques and gives you a relaxing massage. From what this user could understand, it's not any sort of official MGE product, but rather some miscellaneous monstergirl-themed effort that KC just happened to draw the one piece of art for. Furthermore, the alraune massage doesn't even have a "happy ending", so you finish listening a lot more twitchy and frustrated than you were when you started. Blueballed. As. Fuck.
