Sam and Dean were sitting in a diner after a quick salt and burn when he saw Lucifer again, underneath the table. Sam pressed his thumb into the cut on his palm. But nothing, Lucifer smirked.

"Hey, you alright there, Sammy?" Dean said, drawing Sam's attention back to his brother.

"Yea, sorry I thought I-." He looked back underneath the table, but only saw two sets of mud covered boots.

"It's nothing," he finished.

"Whatever, just hurry up and eat so we can get outta here, woulda?" Sam rolled his eyes, picking up a fork to take a bite of his salad. Suddenly, he felt a cold hand sliding up the inside of his thigh; he immediately tensed, glancing down. Sure enough, there was Lucifer, smiling up at him, a finger pressed to his lips.

Then Lucifer starts mouthing at the outline of Sam's soft cock.

Sam dropped his fork back onto his plate with a quiet moan, making Dean look up from the paper he was reading.

"Sam, you feeling alright?" Dean gave him a skeptical look, reaching a hand out to feel Sam's forehead.

"Mm, fine." Sam said through clenched teeth, flinching away from the touch. Dean huffed, shaking his head, turning his attention back to the paper.

Lucifer brought up a hand to rub at Sam's hardening cock.

"Aw, how sweet, you want me, kiddo?" He said mockingly, squeezing harder.

Sam mouthed a sharp 'no, stop' at him.

"Liar." The archangel whispered, unzipping Sam's pants. The noise made him look up at Dean with wide eyes, but he showed no signs of hearing the noise, still reading the paper, probably looking for another case, Sam thought idly.

Lucifer started to stroke Sam's hardening length, while licking lightly at the head. Sam moved a hand to stop the hand on his dick. He wrapped it around Lucifer's, with every intention of making him stop. Instead, he moved their hands faster up his shaft. Closing his eyes, he moved the fallen angel's thumb so it ran over the head of his now leaking cock.

Lucifer chuckled, pulling their hands away.

Sam snuck a quick look back at Dean, moving his plate away. "I'm not as hungry as I thought I was" He stated in way of explanation when Dean looked at him; Dean just shrugged and went back to eating and reading. Folding his head in his arms, Sam looked down at the archangel, who was now sucking on the head of his cock, letting his forked tongue dip into the slit.

Sam bit his bottom lip to keep from whimpering.

"I'm gonna go to the bathroom, and then we can go get you some help, weirdo." Dean gave him another weary look before heading to the restrooms.

"Okay." Sam choked out, looking up at his brother, with what he hoped was a reassuring smile.

Lucifer looked up at Sam then, wrapping his hand around the base of his cock, pumping it slowly while he sucked and licked at the head, lapping up Sam's precome.

"For someone who doesn't want this, you seem pretty eager." He placed an open mouth kiss to the head, and this time Sam whimpered.

"Blow me." Sam commanded heatedly, knotting his fingers in blonde hair, shoving his cock down Lucifer's throat. Instead of biting, which he really wanted to do, Lucifer sucked at the base, moaning around his mouthful.

"Oh God, fuck." Sam moaned into his arm as he came down Lucifer's throat.

"You ready to go?" Dean shoved at his shoulder a moment later, making Sam start and look up at Dean in horror.

"Seriously, man, what's your problem?"

Sam looked down frantically moving to zip himself up, only to find everything in place. He shot a look under the table, mouth gaping open when he saw nothing.

Sam cleared his throat, running a hand through his hair. "Nothing, I'm fine, what's your problem?" He got up from the booth slipping past Dean, rushing out of the diner to the Impala.

Dean threw some bills on the table, shaking his head, as he followed Sam.

"Freak."
