One day they had a fight I don't remember why,but Blaine run away and go to a bar and get drunk,he met a guy and they were just about to have sex when the guy was giving Blaine a bj and Blaine starts thinking about Kurt being alone and worried of were he was and told the guy he was married.The guy go away angry.
Blaine go back to the house and found Kurt worried and Blaine told him what happen but he doesn't seem to be angry so he says that he should be mad at him and hate him but Kurt answer that he was surprised he did'nt do it before,that it was alright cuz he have needs and he doesn't have the most atlethic body and they haven't been intimate for a while and that if he don't leave he will,cuz he did't want to be with him just because he knows he'll die young.
A lot of angst
Blaine/other smut (BJ)
It was a one-shot i think
Blaine knows about Kurt's huntington
The bad thing it's that i don't remember if i read it on Lj or FF :(
