Bold As Brass by F.N. Manning

Will giving up control tame his magic and lead to love?
Oliver Brass is not having a good year. When his once noble family name becomes tarnished by crime and scandal, the wizard’s metal magic stops obeying him. A friendly professor could help him regain control, but the teacher’s illicit extracurricular activities are what truly captivate the metal mage.
A charming professor by day and a devious dom by night, Liam Monroe has the unique ability to control a person’s body and magic. Surrendering to the sexy older man could let Oliver find some peace… and satisfy all his wanton desires.
Liam is exactly who Oliver needs, but their time together is threatened by dragons with a score to settle. Determined to get revenge for the sins of his family, Oliver will need to rely on his magic if he has any hope of stopping the ruthless dragons… or keeping Liam. Can Oliver be bold enough to fight for the man he loves, or will it all go up in flames?
