Dean walked through the dark, mysterious alley. He felt as if someone was watching him.
Little did he know, Vampire King Castiel the Majestic was waiting for this day for 5,666,789 days.
He was thirsty, ok?
Dean got tired of this feeling of being the prey and screamed "Come out now!".
'I came out years ago' Castiel thought.
Dean saw Castiel and thought he was gorgeous, like Donatello, the teenage mutant ninja turtle.
Castiel saw Dean checking out his hot bod so he did the same.
They kissed in a second, against the smelly dumpster and Castiel fell in love.
Little did they know the teenage ninja turtles were watching them through the sewer and they were liking the view.
Castiel and Dean still kissing, saw the ninja turtles and Dean said "Let's put on a show for them". Castiel agreed enthusiastically.
Dean and Castiel kissed harder, with more passion, for their turtle friend's.
40 years later...
Dean, Castiel, Donatelo, Michael Angelo, Leonardo, and Rafael lived together in a house full of love and little hybrid turtle-humans. They were criticized, but their love was too strong for hate.
They lived happily ever after...until Dean and Castiel decided to leave the turtles and became turtle hunters.
They had the advantage of Castiel being a vampire because he could smell the turtles miles away.
They loved eachother and their human children.
End.
