The Honor of Duty

This sounds a lot like the protagonist of " The honor of duty" ( sadly the book dont focus toomuch on the NSFW parts but still a lot of flirting, and a dunamic that sounds very similar to the one you described) Since the MC is the top but yet very clear the submissive one, and his whole thing is that he is basically a male version of the femme fatale trop, he is cute and handsome and he knows that, and he play every card in his hand to make woman basically twice his size eating on his hands
