One day, Blaine was walking through the halls of Dalton. Actually, it was more like he was dancing, cause he likes to do weird shit like that sometimes. He saw Kurt playing with himself, and immediately felt himself grin extremely hard.

"Hello Kurt," he said extremely sensually.

"HI BLAINE!" Kurt started hyperventilating at the sight of Blaine's awesomely sexual face.

"Kurt, I have to be honest with you, because if we're always honest with each other, then I need to confess something. Kurt, I really would like to fuck you in the ass."

"OK!"

So they went into a nearby class room and had some gay sex.
