Fic search: Harry cleaning stables for Draco?

[schwarzglut.livejournal.com]

Hi!
I've been trying to remember either the titel or the name of the author, but nothng comes to my mind...

The students (8th yaers?) build a study group and meet at Malfoy Manor. There is a bet, I think. Harry looses and has to clear the stables. Draco is in heavy denial about being gay. They have sex and fight about it after. Then there is a make up scene in a bathroom ... (??)

Does anybody remember something like that and might help me out please? Thanks! :)
