Interspecies Reviewers Vol. 1

In a world where different humanoid species coexist together and prostitution is legal, brothels are big business and come in a wide variety to please the diverse population, which includes everything from fairies to demons and even slimes and cow-girls. But with so many alluring succu-girl companions to choose from, it’s understandably hard to decide. That’s where Stunk and his band of perverted adventurers come in! These brave heroes have taken it upon themselves to review each and every type of succu-girl to educate the uninformed masses, and they’re determined to leave no species behind!
