Oh wow oh wow. This is brilliant, captivating storytelling. I'm generally not at all fond of "rentboy" fic, but this... this is something else entirely.
Your post-war Draco is so wonderfully jaded. Older, wiser, perhaps mellowed a bit by fatherhood, but still every bit as Slytherin as he ever was. Perhaps even more so in some ways. I absolutely love that he's consciously chosen to be in this profession -- that he's not in this position against his will because he's lost control of his life, but has chosen to be there because he's been able to regain and find personal power in it.
I love the way this fic almost thumbs it's nose a bit at a lot of the "prostitution story" stereotypes:
I could be noble and say that I provide these men with a much needed release, a place where they can be their true selves if only for an hour or two and only under a glamour. I, however, am most decidedly not noble.
The fact of the matter is that I'm a whore because I like sex. I like the way it feels and the way it smells and tastes. I like to come against another man's body; I liked to be fucked hard; I like to fuck hard. Unlike many of my colleagues, I've no ridiculous rules such as no kissing, no coming, no touching in ways I deem too intimate.
Sex is sex, and I'm very, very good at it.
Fuck yes.
You've done a beautiful job of demonstrating the ways in which people inhabiting different roles in their lives can take on radically different personas -- not just through Draco (as father, friend, whore; the Draco/Toby divide), but also through Harry (father, Auror, confused lover). I love the way the lines between the roles gradually blur and eventually disappear here.
I also adore the use of religious symbolism in this.
"Don't always believe what you hear." His mouth curves in a small smile. "There's always a bit of room for doubt."
God. That sex scene in the kitchen melted my monitor a little bit.
And oh my GOD I love you so much for the fact that Draco didn't entirely leave his line of work and "turn over a new leaf" or some equally lame thing in the end. LOVE YOU. Perhaps it's a weird pet peeve of mine, but nothing ruins an otherwise good story/movie/whatever more thoroughly than an ending in which a character "leaves it all behind" to be with their "one true love". Here, you've found a reasonable compromise that still allows Draco to be Draco, and have personal control in his life. Fantastic. ::cheers madly::
