He was doing well until the devil started singing:
"Hello, I love you,
Won't you tell me yo' name?
Hello, I love you
Let me jump in yo' game!"
"Shut up!" Sam shouted, pressing his face into his hands.
"Sammy?" Dean called, "You alright?"
"No!" Sam snapped into his palms.
The impala slowed to a stop as Dean pulled over on the shoulder.
"Come here," Dean commanded.
Sam peeked over his hands at Dean. His brother had twisted around to face him and his arms were spread. Sam's eyes flicked back to Lucifer who was watching with mild interest and an intrigued smile on his face. Sam lowered his hands slowly and slid over on the seat, allowing Dean's arms to enfold him. He sighed heavily and buried his face in Dean's shoulder.
Then Dean slapped his hip.
"Ow!" Sam yelped, jumping up.
Dean laughed slightly.
"Sorry," he chuckled, "Just making sure you're with me."
Sam donned on his best bitchface and Dean just hugged him back to his chest.
"It's ok, Sammy," he whispered, "You'll be ok."
"You should try kissing him now, Sam," Lucifer spoke from the back, "He's all soft and ready for you. Go on now. Smooch, smooch, you incestuous animal!"
Will you leave me alone if I do? Sam thought hopefully. Lucifer smiled widely in surprise.
"I might for a little while," Lucifer said, his voice full of amused doubt.
Sam pulled off his brother's shoulder and smacked their lips together. He gripped Dean's shirt with trembling hands, pressing hard against his brother. He prayed that Dean would understand. He moved his face away and turned to check if Lucifer was gone. He sighed in relief to see an empty backseat. He turned bright red as he turned his head back to face Dean.
"What…what was that?" Dean questioned breathlessly.
Sam bowed his head sheepishly at his brother's inquisitive gaze.
"Lucifer…he said he'd leave me alone…" Sam answered quietly, "For a bit…if I kissed you…"
Sam noticed that his shaking hands were still gripping Dean's shirt and he quickly released it, backing away slowly. Dean's arm tightened around him, preventing him from sliding back to his own seat. Sam looked up in surprise. There was a pause before Dean spoke again.
"Do it again," he demanded.
Sam's eyes widened as Dean leaned up, tilting his head. Sam felt heat rise in his face as he stared down at his brother. He tried to take comfort in the fact that he was still on the seat, though his leg was jammed hard against Dean's and he was lifted up slightly. He panicked slightly before sucking in calming breaths and kissing his lips back to Dean's soft ones. As he pulled off this time, Dean released him and allowed him to scramble back to his side of the car.
"He gone?" Dean asked as he straightened back towards the wheel.
"Yeah," Sam squeaked.
"Good," Dean said as he turned the ignition back on.
Sam stared wide-eyed at his brother for several minutes as they pulled back onto the road. Millions of thoughts rushed through his head why did he ask me to do it again? Did he like it? What does this mean? How are his lips so freaking soft? The last one threw him off a little and he nervously cast his eyes over Dean, who was as stoic as usual. Sam tried to relax back into his seat, assuring himself that there was some good explanation for his brother asking him to kiss him a second time.
"Do it again," Dean said, staring hard into Sam's eyes.
Sam swallowed nervously and glanced about, as though Dean could be talking to someone else in the empty hotel room. Dean had already dropped his bag and was now standing, waiting expectantly by the bed he'd claimed as his. Sam moved forward and dropped his bag near the other bed before stepping up close to Dean. He wiped his sweaty hands on his jeans before leaning down and touching his lips to Dean's. He retreated quickly, but Dean's hands shot out to hold him still.
"Again," he whispered, his voice rustling against Sam's ears like leaves in the wind.
"No," Sam hissed.
"Again," Dean insisted, his grip on Sam's hips tightening.
Sam felt as though his brother's fingers had sent sparks through his system causing him to jump into action and follow the command. Heat surged through him as Dean's lips mouthed against his. He parted his own lips, allowing Dean to suck on the bottom one.
Quite suddenly, Dean forcefully shoved Sam down onto the bed. Sam shivered and shook as he propped himself up on his elbows. Dean was staring at him with dark, lust-ridden eyes. Sam felt his own desire surging in his veins as he tried to make his legs to stop shaking.
"Take your clothes off," Dean instructed, his voice rumbling from his chest.
"Dean, th-this is a bad idea," Sam said in answer.
Dean's mouth pressed in a thin line as he glared down at Sam.
"Take your clothes off," he repeated.
"Dean," Sam pleaded, "We can't."
"You want to bet?" Dean snapped, "Take them off."
Sam trembled, a thrill running up his spine.
"T-tell me to do it one more time," he whispered.
Dean smirked down at his younger brother.
"Take off your clothes," he commanded, his voice low with arousal.
Sam groaned and started pulling off his shirt. Dean watched hungrily as he shakily slipped off his clothes. Sam sat quietly as Dean's eyes drank him in. his hard-on nearly touched his stomach as Dean made noises of approval above him. He watched anxiously as Dean's hands found his own belt and swiftly pulled it off. Sam twitched all over as ideas ran in his head.
"Spread your legs, baby boy," Dean ordered quietly.
Sam whimpered slightly, but spread his knees, giving Dean full access. Sam barely had time to react as the belt whistled through the air, landing on his left thigh. Sam let out a strangled cry and gripped the sheets tightly. He panted heavily and pried his eyes open, suddenly aware he'd shut them.
"I thought you'd like that, kinky bastard," Dean smirked.
Sam tried to tell him to fuck off, but his words caught in his throat as Dean's hands, now void of the belt were slowly undoing the fastenings on his jeans. Sam's mouth felt dry and his palms felt sweaty as Dean moved the last step forward and brought his arousal out for his little brother to see. Dean's knees hit the edge of the bed and he stared leaning forward to straddle Sam, his mouth lining up with the taller man's.
But then, as per the luck of the Winchester Brothers, Dean's phone started ringing. Sam blinked owlishly and Dean frowned deeply. The ringing went on for a few seconds before anyone spoke.
"You gonna get that?" Sam questioned rather breathlessly.
"Uh, yeah," Dean answered, "I guess."
He pulled away and fished his phone out of his pocket.
"Shit," he muttered, "It's Bobby."
He pulled further away as he answered.
"Heya, Bobby," he called into the phone.
Sam buried his face in his hands and groaned.
"I told you this was a bad idea," he mumbled.
