Fic search

[abrighterdawn2.livejournal.com]

Hey guys I'm looking for a specific fic and I'm hoping someone can help me find it. It was a chaptered fic and I can't remember who by. There was an accident in potions class and Harry and Draco were bonded(a slave bond?i think?)because of this. I remember that Snape lied and said that because of the way their hands were positioned was the reason Draco was the "slave/sub" to spare him embarrassment. I know that harry spanked Draco as punishment because the bond demanded it. I remember that they got married at hogwarts I think to change the slave bond into a marriage bond. I also remember Harry, Draco and snape taking a trip to London, to view Harry's properties. I hope it rings a bell for someone, all help appreciated.
Thanks.
