Pervert's Guide to Properly Loving Monster Girls

"Kiddo, I'm sendin' ya to a fancy school to learn how to f*ck monster girls!" The barely 5-year-old boy at the time blinked in confusion at his grandfather's words. Despite not knowing what was going on, he agreed with enthusiasm after seeing how happy his grandfather looked. Little did he know that he would eventually become an existence that was too tempting for any woman to ignore... In the Carven Empire, a beautiful place high in the sky amongst the clouds, Cain Alderman studied his d*ck off, literally, to become something known as a 'Child of All.' A 'Child of All' is a rare existence, mostly because they are biologically different from other races. He was still human, but his genes were special, in that they could adapt to any humanoid species, allowing impregnation to occur between two different species. Cain had an amazing opportunity ahead of him and after graduating from the Academy of Monster Genetics, he decided to pursue more hands-on research back in his hometown he missed all these years ago. Now 18, how will he spend his time as a specialist in impregnating women? Will it be everything a man could dream of? Or will he f*ck off more than he can c*m? - - - R-18 novel with lots of smut, impregnation, and some furry vibes. Wide variety of monster girls, kinks, and tags you might find on a certain site with digits ;) There will be a bit of cucking but no NTR otherwise. He's helping women give birth after all since the men of this world can't do their job. He will not be emotionally attached to most, but they are treated no differently than humans. They have the same level of intelligence and WILLINGLY allow him to impregnate them. Monster biology works differently in this world but will be explained in the story so I apologize for the info dump ahead of time. Not everything here in the synopsis is to a T but it is a pg version of what happens in the first 10 chaps. This is a slightly darker setting with some politics to even out all the smut that will eventually cum.
