Disclaimer: I own nothing but my own words and imagination. If I did, this would have really happened.
This is part three of my Firsts 'verse but each story is stand alone and if you don't like het you may not want to read parts one and two. Part one was Dean's first time and part two was Sam's. This chronicles their first times together.
This was all so new. Dean had never been with another man and to the best of his knowledge, neither had Sam.
