Sex Before Love (Drarry)

A few years after the War of Hogwarts and the death of Lupin, Fred, and countless others, Draco and Harry run into each other at the train station, both waiting for their kids.
----------------------------------------------------------------------------------------------------
Their marriages have both gone downhill, with Ginny cheating on him with Seamus, and with Astoria divorcing Draco because of, well, I guess that will be divulged later.

Draco invites Harry to go out drinking, to celebrate their kids both getting invitations to Hogwarts.
(Two years late, but it's the thought that counts.)
----------------------------------------------------------------------------------------------------
They both get drunk off their asses, and things get hot and heavy.
The next morning, Harry realizes what he did and runs out of the bar before Draco wakes up, with aching hips, promising himself that it will never happen again.
----------------------------------------------------------------------------------------------------
But it does. Again. And again. And again.
Soon, Draco, who doesn't have a wife on the side, begins to feel more than just lust and desire for Harry, his old nemesis.
How will Harry react, when he still loves Ginny?
(Even though she's clearly moved on from her Hogwarts sweetheart.)
----------------------------------------------------------------------------------------------------
**WARNING: I am almost completely ignoring the "19 years later" epilogue. They marry the same people, they have the same kids, but there is no specific amount of time between their graduation and the marriage. It could be two years (Ew), or it could be thirty, for all I care. (They would be pretty old by then, though)**

Disclaimer: If I owned Harry Potter, Cedric would still be alive, Harry and Draco would be fucking each other senseless every night, and Blaise and Neville would be the cutest couple to ever exist in Hogwarts. So no complaints.
