Stiles gets Allison pregnant

[multishipperdh]

Hi, I'm looking for a where for some reason Allison and Stile have been distant from the pack and they start hanging out. Allison is pining over Scott and Stiles is in love with Derek. At some point I think they get drunk and have sex but agree that they should just be friends.

However, their one night stand results in Allison getting pregnant. When she has the baby, she and scott are back together ( I think there is also a sterek endgame) and he adopts the baby.

Please someone help me, its driving me crazy.
