One Night (sterek mpreg)
Surely not much can happen in one night, right? Wrong.
When Derek and Stiles are drunk at Lydia's party, things get a little heated... Sexually.
What neither of the boys knew was that Stiles happened to be the mate of werewolf, Derek. This fun night soon took a turn for the worst a couple of weeks later when Stiles is experiencing some... changes.
How will Derek cope with the news? And what'll happen to them? To the baby?
SORRY THIS DESCRIPTION SOUNDS SO BAD I PROMISE IT TURNS BETTER
