Oh my God. I want to be able to write emotion like this. I cannot... This was just beautiful. 
 There just aren't enough excellent younger Dom, older sub stories, and this one rises to the top of the list with a bullet. Toby has this innate ability to be dominant in a way that pushes Laurie's buttons without exactly knowing what he's doing. He's really winging it, and you can tell. But his mistakes aren't with his lack of knowledge of "what it means to be a Dom" (which is what Laurie likes most about his dominance), but rather the fact that he's nineteen, and he's still learning who he is and what it means to be out on his own. 
 And Laurie just can't believe that nineteen-year-old Toby wants to stick with him, because he's so young and Laurie's in his upper thirties. He tries to keep Toby at arm's length, and by the time he realizes that's a mistake and he wants Toby to stay, Toby's had enough of doing everything on Laurie's terms. 
 So much win in this story. Just beautiful.
