It took place during the goblet of fire and Harry for some reason had to move into snapes living area. And Harry was having trouble sleeping, I can’t remember how it started but Harry would fall asleep sucking on snapes thumb/finger while Snape laid behind him. And at some point when they have sex or near when they do Snape tells Harry that he believes the idea of him was conceived when Snape/lily/regulus had a drunk threesome.

I cannot for the life of me remember the name of this fic and those are all the details I remember. Hopefully someone knows wtf I’m saying lol.
