The fic I'm looking for was from Sam's POV and was fairly long. There was a lot of Sam who was in high school pining for Dean who I don't think was. I remember two scenes clearly.

1) Sam and his girlfriend call Dean from the high school bathroom stall they're hiding in because someone's running around the school with a gun. Dean gets to the school and runs in and finds Sam and the OFC in the bathroom. Dean may have fought the shooter, but I can't remember. They all get out safely.


2) Dean's girlfriend and Sam's girlfriend come over for pizza and a movie. As they're watching, Dean's girlfriend kisses Sam's girlfriend and they all start to get physical on the couch. But Dean drags his girlfriend into a nearby bedroom and they have sex while Sam and his girlfriend listen from outside and Sam gets a handjob. Next morning, Dean's girlfriend wakes Sam up and has sex with Sam while telling him that there's nothing wrong with him and Dean having sex. Later on, Sam finds out this girl had had sex with her own brother but only because they were abused at a young age.
