Draco Malfoy, Head of Veela Affairs at the Department of Magical Beings, does not do people favours. Harry Potter, recently turned werewolf, is not "people" - not to Draco anyway. Does Draco plan to fall in love with Harry when he decides to help him? No. Does he end up falling in love with him anyway? Pft, what do yo...
They haven't fucked in over three months now; or maybe it's been longer. The last time they fooled around at all was a week ago when Harry woke Draco up by sucking him off, before promptly getting interrupted when Scorpius came banging at their bedroom door. It's always worth the wait when it's been a while.
"After he accidentally gets Malfoy pregnant on a drunken fuck at a club, Harry doesn't anticipate that it'd be just as easy to fall in love with him."
