Explanation of the plot "The Childrens of Eva"

Some patrons do not understand the story of the new season of beautiful creatures and everybody is asking me the same thing lol (surely my mistake) so I will explain a bit the main idea of the plot of this new comic

In one part of the story Eva asks the same question to River, Why Female humans pays for sex with orcs and goblins?  and she replies that the orcs were eliminated because humans thought that these  creatures raped the elven females, but soon the humans realized that these elves enjoyed being fucked by the orcs. 

River began to wonder why these elves enjoyed having sex with these horrible creatures so much? Why did they  even defend the orcs and the goblins of humans? Is it that they do not  understand humans just want to save them? then it was when River secretly decided to save Eva's sister (Shera) and her two goblin  children...   

Shera answered all her questions and it was when River for the first  time in her life was fucked by goblins and her huge cocks and understood the enormous pleasure that the elves felt...  She gradually convinced some close femele human friends to share her sexual experience with the goblins... it was then that an exclusive  group of women secretly arrived in the lands of River (lands that were quite far from the human kingdom) just to have sex with these creatures,  all in secret... 

River decided to take advantage of all that... So now  she is the owner of a kind of  brothel for women...  Eventually Eva and shera knew several orc hiding places and they revealed the information to River so that she would go to look for them and take them to her lands... 

little by little the population of orcs  and goblins in the river lands was growing and many more human females went to River lands to enjoy great and intense pleasures, which were  not cheap... not all human females were able to pay the price that River had imposed... 

From there many things begin to happen (really Hot things) but you should  better wait that the comic advances.
