Our Demon King Doesn't BIte - demon lord

I am incredibly envious of a world where even the Demon King and the Hero are pets! In this setting, would having sexual relations with the Demon King be classified as bestiality? In the story, there is a master character who falls in love with a skeleton pet, but the surrounding characters do not particularly express any hatred or repulsion.
