The fic I'm looking for has Kurt and Blaine dating at Dalton. I think it's written from David's or Wes' POV. They walk in on Blaine trying to rape Kurt, then they save Kurt and explain to him that Blaine thinks raping someone is showing love because his first boyfriend convinced him to sleep with him because they love each other or something like that.
Blaine has had other boyfriends before and he raped them as well, and Kurt is horrified to find out that he was never punished for it. Then I think Blaine's father shows up, trying to bribe Kurt into not going to the police with money.
I'm pretty sure it had like 3-4 chapters and was abandoned. I saw it at ff.net .
Thanks a lot in advance!
