You and Sam had always been close. Even since you were kids and Johny used to drop he and Dean off at your dad's place for weeks at a time during hunting trips.
When you and Sam became adults, you both agreed on a no strings attached relationship. This went on for a full year. You were okay with this. Because, honestly, you were a mess. Broken. Damaged. So was Sam. So this was perfect... until it wasn't...
Sam was currently addicted to demon blood. You didn't know that, though. This was all part of his plan to stop Lilith. One night, you were outside, smoking a cigarette when Sam approached.
You two got into an argument when he blurted it out. Three words that would shatter your world. Three words. Three simple words with so much meaning. Three words that made you feel like the biggest piece of shit ever for using Sam as a release.
"Because I love you!" Sam blurted out without thinking as he tried to take the cigarette.
