Here is a Castehaste doujinshi that I found on Myreadingmanga.com. I want to say thank you so much to whoever put this online! I have this doujinshi so I am thankful that I don't have to bend my copy to bring this cuteness to the Internet. I haven't read the manga of this yet but it is on my reading list. The snake boy is in love with a hamster boy and ends up having kids with him. I have heard that in the main manga they don't end up together though so that sucks. Yuzotys art is amazing and her men are so hot! Hope everyone enjoys!
