Wincest- Memorial Day

"Sammy...How could you do this to me?" Dean yelled.
"I'm sorry, Dean Bean... I really am... I just- I have to."
"I love you, Sammy. I love you, please don't go. Please don't leave me!" Dean pleaded. But at that, Sam turned and boarded the ship. Dean's tears began to fall harder, the concept of losing Sam was so alien to him. He stood in shock for a minute before leaving the platform. 'The army? They've got no right to take him away from me.' Deam thought 'Fuck the army.'

After a year, Dean rarely ever left the house. He'd forgotten the warmth of having Sam lying next to him. Each day, he looked at pictures of them together to keep those times fresh in his mind. 6 days later, he got a letter. Not from Sam, but from the army. Saying that Samuel Winchester had been killed in action.
Gasping, Dean woke up, sweating and shaking.
"Dean Bean, what's wrong?" Sam asked, concerned "Have a nightmare?" he held him in his arms lovingly.
"Y-Yeah." Dean replied, voice shaking.
"What happened?" Sam kissed him "Come on, baby, I can help." Dean nodded, paused, then spoke.
"Y-You were drafted... Into... The-the army." Dean shivered "It was a year and then I got a letter saying that you were- were-" Dean buried his face in Sam's shoulder.
"Shhh, baby. It was just a dream. I'm right here, I would never leave you, Dean Bean." Sam comforted him "It was probably all the hype about Memorial Day."
"I love you, Sammy. I love you." Dean whispered in Sam's ear.
"I love you too, baby." Sam purred "Not even the army could take me away from you."
"Promise?" Dean asked innocently.
"Of course I promise, baby." Sam replied "But... umm... you have to make me a promise too, okay?"
"Anything, Sammy."
"Remember a few years back... With... Lilith?" Sam spat the name.
Dean shuddered "Y-Yeah." he whispered.
"Never do that again. I-I thought I'd never see you again. That's why I'll never be able to thank Cas enough." Sam crushed his lips to Dean's, tongue begging entry. Dean obliged, opening his mouth to let Sam's tongue dance with his, exploring his mouth.
"Happy Memorial Day, Dean Bean." Sam whisperd breathlessly as they parted for air.
