[Karasu Chan] The Best Succubus

A faithful succubus wife gets teased by her drinking buddies for refusing to cheat on her husband—apparently devotion makes her a 'shameful' example of her kind. In tears on the walk home, she's met by a husband who reassures her she's a great succubus before claiming her plump ass for a sweaty, all-night anal session, drawing out her vow to think only of him and begging him to cum inside her. Come morning she's still at it, worshipping him with her mouth and huge breasts while shyly asking if she's really a good succubus, earning the affirmation that gives the story its heart.
