It was pouring out. Good reason to stay inside. Their father was on a hunt and wouldn't be home for a few days. A much better reason to stay inside.

They hadn't been able to be alone with each other for more than two minutes. That was the problem with being with their dad.

Dean walked up behind Sam slowly and quietly, using his stealthy 'ninja' abilities to his advantage. He brought his hands up to his brothers shoulders, and gently began squeezing all the tension out of them. Sam tilted his head back just as Dean brought his own down closer. Their lips pressed together, at first gentle, but then Dean tightened his hands on Sam's shoulders forcing his brother to jump up and let out a small groan. Sam could feel Dean smirking and brought his hands up to his brothers face and slowly pushed his face away from his own.

"Don't start Dean. I have to do this research." He said as he stared into Dean's deep green eyes, seeing the disappointment in them... or was it something else?

"Fuck the research Sammy." Dean said as he walked around and faced his brother, clicking the laptop shut in the process. "There are other things that you should be 'doing' other than research."

Sam let out a laugh. "Oh yeah? Like what?"

Dean grinned. He reached his arms out, placing his hands on the arms of the chair and leaned forward, bringing his face in inch away from Sam's. "Do you really have to ask?"

Sam grabbed the collar of Dean's shirt, bringing their lips back together, as Dean straddled his brother. They broke the kiss for only a second as Sam pulled Dean's shirt over his head and connected again like magnets. Sam's hands running over Dean's body as much as he could while Dean's hands went straight for his brothers jeans. Easily undoing the belt and unbuttoning the one button that was beneath it.

The room was hot with the heat that the two men were giving off. So enthralled with being able to grope each other as much as they wanted.

That is until they heard the sound of the engine of a certain truck shut off, and the sounds of a metal door opening.

"Dad!" Dean and Sam said as they broke the kiss instantly and stared at each other. As soon as they heard the sound of the key trying to unlock the door, Dean rolled off his brothers lap and lunged for the bathroom. Sam sitting up straighter in his chair and moving it so his lower body couldn't be seen from anywhere else in the room and quickly opened the laptop just as the door opened.

"Boys I'm back." John said walking through the door and dropping his duffel bag on the floor. "Damn, don't you guys know how to open a window? It's as hot as hell in here."

Sam just kinda off looked at him, giving a half hearted laugh and looking to the floor, only to see Dean's shirt laying right beside his own belt.

'It's gonna be a long night.' Sam thought as he heard the shower start up and instantly wanted to kill Dean in his sleep for leaving him out in the room alone with their dad.
