Charlie's been a regular choice of Mr. Luthor's for the couple years. He doesn't like to admit but over that time he has come to care for the bald man. Not romantically, of course, but he's a fragile guy despite all his power and prestige and Charlie believes in a doctor-patient like confidentiality between himself and his clients. 

And Mr. Luthor is a very special client. He pays better than all his other clients combined and he is deeply concerned with Charlie's pleasure when they come together. He's a decent man who doesn't ask for anything too bizarre and somehow finds it in himself to treat a prostitute like an equal. 

That doesn't mean Charlie doesn't notice. He does. He knows there's more to the way that Mr. Luthor rolls him onto his stomach and fists his black hair than pure preference of position. It's definitely not his name that Mr. Luthor groans as he shakes and comes in and over him. 

Charlie brings it up once in the friendly afterglow of good sex and good brandy, who this Clark guy is. Why he doesn't just talk to him about this, he obviously loves him so much. 

Mr. Luthor's face falls for a split second before he collects himself. Then he shrugs and says simply, "He's straight and in love with someone else." 

About a month after that, Charlie finally sees the mysterious Clark across the room at a fancy party he is at with another of his clients. He is gorgeous, body of a Greek god and the face of Adonis. And the looks he gives Mr. Luthor  are so intense that they shakes Charlie to his core. 

He tells Mr. Luthor so at their next meeting. After Mr. Luthor fucks him blind of course. 

He's going to miss the extra revenue but when Mr. Luthor never contacts him again, Charlie isn't all that upset. The man is finally getting what he wanted. Of course, the ten million dollars and a really stellar health plan under LexCorp's name as a 'thank you' gift deposited into his bank account doesn't hurt either.
