Any comments pointing out that the age difference between Lucifer and literally anyone else he'd ever slept with was vastly greater than that died about midway into the rest of what Duke was saying.

Curiously, the rest of it made him feel something almost like fear. He didn't understand that at all. Coupled with it was an impulse to let go of Duke's hand, but he stopped himself from doing so just in time.

The rest of him felt deeply out of his depth, and he was silent as he stared at the picture and groped for anything he'd ever been through that might be helpful.
