Based on Season 1, Episode 8 "Bugs"
Prompt: "I'd take our family over normal any day", "I wanna try the steam shower" – Dean
Sam sighed as he heard the sound of the shower going again. He rolled over and pulled the blanket back up over his head. He was already worn out, not to mention squeaky clean, from the shower he had had last night. They had had. He groaned into his pillow.
They had pulled the Impala into the garage and gingerly ventured into the house, Sam following behind. When he judged himself at an optimum distance, Sam slapped Dean on the arse, laughing as his brother turned round.
"Dude?! What the hell?"
"That's for hitting on me in public – fair's fair."
"But it hurt," Dean moaned as he rubbed his backside in a comical manner. Sam just grinned.
"I'll go and get some blankets out of the car" He said, heading back out to the Impala.
"In that case, I'm trying the shower!" Dean smirked happily.
Sam had just opened himself a beer, having set out two rough beds on the soft carpet, when he heard some deep groans from upstairs. Raising his eyebrows, he climbed the steps and paused outside the bathroom door. Dean moaned again.
" Dude, you better not be getting off in there – we're only squatting, remember?!"
"Yeah, yeah" Dean called through the door.
"Well, leave me some hot water." Sam shook his head and began to head back down the corridor when the bathroom door swung open, Dean reaching out to grab Sam from behind – manhandling him, clothes and all, under the hot water.
"Dean!" Sam spluttered, but his brother was already pulling the wet clothes away from where they hung on the taller man's body.
"I thought we decided not to do this again," Sam chastised, feeling Dean's lips on his neck.
"Showers make me horny" Was Dean's only offer of explanation as he found Sam's mouth with his own. "Besides," He added, pushing Sam up against the tiles, "this shower is awesome"
And Sam couldn't help but agree.
