Broodmare (Mephisto x OC-Reader)

Mephisto Pheles, director of the Japan Branch's True Cross Academy, swindler, older than most memory, swindler, Demon King also known as Loki, the Raven, and King of Time, and whose true name is Samael. Samael generally comes off as a combination of carefree, nonsensical, and needing for nothing. But even a demon has... needs, right? Well, yes, and also no. Mephisto has no interest in any.... relationship standards. That being said, being of demon royalty does have complicated rules, it's not all fun and games, as much as he hates to admit it... one of these rules is to produce an heir... now he would never go back to Gahenna that's a given, which means he would need to take a page from his father - Satan's, old playbook, which means human stock. "There is a new young woman applying for a teacher's aide, or assistant position... perfect. let's have some more adult rated fun... hentai knowledge, don't fail me now!"
