WE BECAME THE WIVES OF BEASTS TODAY! Vol.1 (Yaoi Manga)

Yuya Asabuki is a young boy who lives with his older brothers. One day, he accidentally opens up the ancient shrine that was in his back yard, and three handsome Inugamis (dog gods) appear from inside. They insist that they will take Yuya and his brothers as their brides as a payment for being locked in the shrine by Yuya's ancestor. Yuya's partner dog god's name is Akatsuki. He is rough and insensitive. Yuya refuses to be his "wife" as he refuses to marry a man, but Akatsuki takes him to bed. Turns out Inugamis need to copulate with their wives to get energy... Vol.1, 50 pages.
