This is only the first 24 pages of the full 54 page chapter that's on his Fanbox. (Though, maybe you're the artist and already know that, since the file naming suggests this isn't from Pixiv. Still, the gallery isn't named correctly.)
Anyway, UnderBelowYou is my favorite new Koikatsu artist who create psychological femdom stories, alongside Updra. It's cool how unpredictable Cash Queen is, despite the fact you know that the destination is a protagonist in debt to a mysterious domme. I hope his friend (not depicted in this short gallery) gets the girl...
Im sorry im just a silly fan and honestly don’t really know how this site works yet. I’d really appreciate it if you could tell me how I’m supposed to do it properly. I was trying to give the artist credit too, my bad 😭
