I'm trying to find this recent doujin I've read recently, but couldn't find it. Thought I'd followed the artist on Twitter, but apparently I didn't. He only has 1 (?) work so far, so he's sorta new, and I want to find out what else he's been cooking. Tried to look up the tags, but didn't find anything.

Basically the premise was that Japan isn't having enough sex/babies, so students can enter a shed in the school yard and listen to the voice box telling them what to do. There's a gloryhole/curtain blocking each side, but they ended up finding out about each other anyways.
