Fics like Three Whorehouses

Byleth Eisner is a man who has earned the title "Ashen Demon" due to both his killing talents, and because he has never shown emotion. No rage, no sadness, no joy. And no love. But all that changes when he meets the very haughty and perverted goddess named Sothis and finds himself employed as a teacher. Now, surrounded by beautiful women and finding his libido passively supercharged by Sothis, will Byleth manage to keep his emotionless facade and stave off his urges? Spoiler alert: No. No, he doesn't
