Well, I guess I would have to reckon with this series someday, so I might as well take advantage of this month's theme and do so now.
INTERSPECIES REVIEWERS (Ishuzoku Rebyuazu), written by Amahara with art by masha. First published in 2016 and first published in North America in 2018.
PLOT:
In this particular fantasy world, sex work is just an everyday part of life and many brothels take advantage of the various species and magical encounters available to cater to just about every sort of clientele possible. The human adventurer Stunk and the elf Zel have made it their mission to try out every sort of girl and service available and rank their experience for a bit of coin. Along with their reluctant angel companion Crim, they'll do it with anyone: succubi, salamander women, fairies, elves, and so much more.
