Chapter 10: In Every Sense Of The Term

Dean would have liked to have convinced himself he was imagining things, but his life had a certain track record of everything that could possibly go wrong indeed going wrong, so unfortunately, he could quiet easily believe this. As much as he didn't want to.

"Sam's pretty damn clever, isn't he?" Garth commented from behind him.

Dean sighed, shaking his head. "Too clever. But he's also too reckless." He kicked out at the wire bars on the floor angrily, twisting his head to stare up at the small- but just damn big enough for someone to fit through- open window. "Dammnit, Sammy."

"You know, Sammy, I thought you the whole point of our little arrangement here was that you could get some sleep. We're kind of defeating the point here."

Sam sighed, trailing his fingertips down Lucifer's jawline with a languid shrug.

It was nearly three in the morning but he hadn't slept a moment. He wasn't even undressed, still lying on top of the covers as he had been for the past few hours, simultaneously wondering if he'd gone mad while continuing to feel every little detail of Lucifer's face.

"Don't tell me you've lost your soul again, Sammy," Lucifer said. "Dean would likely blame me for that, too."

"Forget Dean," Sam whispered. "He's not blaming you. He's just... He doesn't understand."

"You've said that a good fifty times now, Sammy."

Sam sighed, shifting his hand down to play with the collar of Lucifer's shirt. "I just... I don't want to think about anything else right now." He pulled the collar down slightly, staring blankly at the curve of Lucifer's neck. "I can't do it anymore. I need a break. Leviathans, Cas, Dean, Bobby..."

"You care too much, Sammy."

"Maybe. Maybe that's it." He gave a small, bitter smile. "Perhaps I'm just too soft. I should be kicking you back downstairs, not... Not this. I have the devil at my mercy and what do I do?" He didn't specify, but they both knew anyway. Sam shook his head. "I've gone mad."

"Does that mean I win?" Lucifer asked with a smirk.

Sam huffed in vague amusement. "Won what exactly? It used to be about getting inside me. 'A wrestling match inside my noggin' as you put it. So what game are we playing now?"

"Oh, I don't know, Sam, it might still be about getting inside you."

For a few moments, Sam just stared at Lucifer's face, at the far too amused expression, the corner of his lips just upturned, those blue eyes staring at him with a whole other kind of desire. It wasn't even a suggestion, they'd moved beyond that. They were so close, knew each other so well, blushing and getting flustered seemed silly and pointless.

Fine, Sam thought. You win.

He didn't give verbal consent, though from the glint in Lucifer's eyes, he knew the devil could tell what he was thinking. But for once, Lucifer didn't comment, merely shifting on top of him, smirking all the while. As a matter of personal pride, he would not be made to say yes to Lucifer a second time.

The half-whimper, half-groan Lucifer got out of him was a good consolation prize, however, as the devil's tongue slipped deep into his mouth, their hips pressing together as Sam unwittingly arched against the bed with an eagerness that portrayed just how long he'd been waiting for this.

I want you.

In a matter of moments, all the control he'd had abandoned him to be replaced with a jumbled mess of thoughts that seemed to short-circuit with every little movement from Lucifer on top of him. He was vaguely aware of kicking off his shoes, then losing his shirt so fast the buttons must have been ripped rather than undone. And without even consciously thinking about it, he was pulling at Lucifer's clothes, feeling his way to get them off as he was too distracted with kissing to bother keeping his eyes open. The cool air- from Lucifer's body more than the room- made his skin break out in chills, his mind and everything else numb as his blood seemed to have abandoned all other body functions to travel quickly south.

His hand reached up to cup the back of Lucifer's head, gripping the dark blonde hair between shaking fingers. He could feel his jeans being pulled off, vaguely noting the sound of the material hitting the floor, he went to reach for Lucifer's belt, but the devil pulled back suddenly, breaking the kiss and Sam groaned in protest.

He blinked, briefly too disorientated to even focus his vision, before slowly turning to look up at Lucifer straddling his waist. "What?"

To his surprise, Lucifer was staring just vaguely off to the side, seeming... Hesitant.

"What?" Sam repeated, slightly louder as he propped himself up on both elbows.

"You're a human, Sam," Lucifer said suddenly.

Sam frowned. "Yeah," he said slowly with a small laugh. "Last I checked."

Lucifer turned to face him, expression serious as he gently ran one fingertip along the pattern of Sam's anti-possession tattoo. "I hate humans, Sam."

Sam bit his bottom lip, unsure of how to respond. "And I hate some angels," he said eventually. "And demons. Most demons. Don't look at everything so generally. Yes, I'm human, but I'm also Sam. And you're also the devil. Satan. Evil, supposedly. But you're also Lucifer. And I love you, Lucifer, no matter what else you are."

He hadn't really been aware of his own way of thinking until now, but as he said the words aloud, an unplanned stream of consciousness, it made sense.

Lucifer's sharp eyes travelled up to meet his, holding the gaze for a few moments, before he leant in and kissed him once more. The two of them lowering back down onto the bed together, lips never once breaking contact as Sam took the chance to undo his belt and throw Lucifer's jeans over the side of the mattress.

"You were right," Sam said, breathless as he leant back. "We were made for each other entirely. I need you and you need me."

"Two parts of a whole," Lucifer whispered, voice husky against Sam's lips.

Sam shook his head. "No," he said. "Two different wholes that go together. That rely on each other. You're like my shadow, my echo. Always with me, in some sense, at least." His voice trembled on the last few words, all semblance of control over his own body slowly slipping away as Lucifer's hips ground against his.

He felt the chill on his skin as his briefs were pulled away, leaving him fully exposed as Lucifer's cool hand travelled down his torso before brushing just briefly, teasingly, over his erection.

He grit his teeth, head tilting back as his lips parted with a choked moan.

Lucifer studied him slowly, hovering above him as the cool blue eyes took in every detail of Sam laid out before him. Sam had always been so very pretty. He'd wanted him as a vessel he could dress up and look the part in, the regal boy king. Then again, if that had been the case, he wouldn't have been able to admire him so easily as he could now with Sam pinned on the mattress beneath him.

He dipped his head down, kissing Sam's anti-possession tattoo, then further down, his chest and abs, so perfectly sculpted. He hovered over his hips, smirking as his gaze flicked up to briefly admire the look of pleasure on Sam's face, before he ran his tongue, forked as it was, up Sam's shaft, relishing the in the half-sigh, half-moan it drew, before pulling back. Sam groaned.

No, Lucifer thought idly. This is my best torture yet.

"Lucifer... We... We need..."

"Please, Sammy, I can still pull off a few tricks." Lucifer ran his hand down the side of Sam's face and he felt the cold, wet substance of lubricant.

Sam choked out a laugh. "The devil's great power," he teased.

Lucifer ignored the comment, pulling off his own underwear and stroking his hand over his own length, smirk lingering on his face as he saw Sam eagerly watching his every movement.

Sam groaned, wriggling under the devil kneeling over his thighs, desperate to get him to hurry up. He was almost embarrassed at his own impatience. He'd never even done it before, not like this, with... But his partner's gender was the least of his concerns right now. The milestone of being about to have sex with another man was rather eclipsed by the fact of being about to have sex with the devil. Yeah, no big deal.

A half-moan, half-gasp stuttered out from between his lips. Briefly enclosed in his own thoughts, he hadn't noticed Lucifer dip down to run that damned forked tongue teasingly over his length once more. Sam's hips bucked, sweat breaking out over every inch of his body as Lucifer playfully brushed the two tips up either side of Sam's cock.

"...damn." His hand grasped blindly at the air until he grabbed hold of Lucifer's hair, keeping the devil and his icy breath right where he wanted him.

Lucifer, meanwhile, still hand one hand on his own length, coating himself in enough lube to make it less painful for Sammy. He would never hurt him, not really. It was a strange situation to find himself in, though. He'd never thought to use a vessel (or at least this representation of a vessel) in such a way, though a few times back during apocalypse-is-now he'd indulged in a few acts of experimental self-pleasure always while engrossed in thoughts of Sam which he convinced himself were merely about achieving his own perfect form in the Winchester.

"Please," Sam whispered as Lucifer pulled back, staring up at the devil with desperate bright eyes. So very, very beautiful. "Now. Please."

"Say yes, Sammy," Lucifer grinned, parting Sam's legs and settling himself between them nonetheless.

Sam groaned and gave him the most powerful glare he could muster, which is his current state was not much. "Not funny," he insisted.

Lucifer chuckled, gently running one finger, wet with lube, around Sam's entrance. "But I'm an angel, Sammy. I need your consent."

"You have it," Sam growled, clenching the white hotel bed sheets in both hands.

"Say yes, Sammy," Lucifer insisted, absentmindedly trailing his fingertips up Sam's length.

Giving a shaky half-gasp, Sam cursed his own weakness. "Y-Yes," he whispered.

Lucifer casually tilted his head to the side. "Excuse me?"

Sam grit his teeth, his mind adamantly refusing to admit the aching in his cock was in response to this teasing. "You heard me. Yes."

Ignoring the devil's satisfied smirk, he let Lucifer spread his legs, arching his back as Lucifer caressed his entrance with surprising care, before slowly pressing the tip of his cock inside Sam's wanton body.

Sam clawed at the sheets, hair clinging to his face with sweat. He was sure his heart briefly stopped at the sudden infiltration, overwhelmed at the strange, unfamiliar experience of being stretched.

"Relax, Sammy," Lucifer whispered, reaching up and running one hand through Sam's hair as he eased further inside him. Despite his appearance of control, his voice shook slightly, a faint sheen of sweat covering his skin.

Sam gazed up at him appreciatively, hands fumbling upwards before coming to rest on Lucifer's upper arms. He wasn't as finely toned as Sam himself, but rather strong and firm, the authoritative form of a man in charge. Sam decided he liked that.

"You're too tense, Sammy." He pushed deeper, cherishing the look on Sam's face that was caught somewhere between discomfort and pleasure. He wrapped his hand around Sam's length, gripping and stroking until Sam unwittingly unclenched enough to allow Lucifer to thrust fully inside of him.

Sam cried out, a broken scream that seemed to dissolve into a moan as the previous discomfort abruptly gave way to an intense pleasure as Lucifer hit on a spot he hadn't even known existed until that moment. It seemed to unlock something inside of him as basic instinct took over and he found himself raising his legs slightly higher for better access, wrapping them around Lucifer's waist as he rocked his hips in time with the devil's thrusts inside of him.

They built up a rhythm, moving together as if they truly were one. Sam gripped Lucifer's arms tighter, digging his nails into the soft flesh, marveling at how he felt so simultaneously hot and flustered while Lucifer's hand still stroking his cock was so perfectly cool and stimulating. He could feel a burning heat pooling in his lower stomach, the blood rushing in his ears and suddenly a glorious burst of light as his vision briefly blazed white. When he managed to blink the world back into focus, mind numb with pleasure and his cock burning, he looked up to find Lucifer's wings spread above him.

He wasn't sure what made him do it, but he reached up and clenched a handful of the pale feathers and to his great delight, Lucifer actually moaned, faltering briefly in his previously confident rhythm, back arching as he thrust deep inside Sam. The hunter figured wings must be a sensitive spot and grinned at the discovery. They shuddered together, the desperation building within them both as they grasped for one another, Lucifer's hand on his cock, Sam's fingers gripping Lucifer's feathers.

One more thrust and Sam couldn't hold out any longer. With a strangled cry he came over Lucifer's fingers, with a pleasure so intense he was briefly convinced he was going to black out, before it was abruptly redoubled as he felt Lucifer spill inside of him. His hands shook and he unwittingly released the feathers, Lucifer's wings arching up toward the ceiling in climax for several long moments until they were both done and the devil collapsed on top of him, his wings suddenly drooping, two great feathered limbs falling limp over the sides of the bed.

Sam fell back onto the mattress, gasping for breath, burning all over though Lucifer suddenly felt so pleasantly cold on top of him, like a constant rush of cool air on a hot day where both temperatures seemed to compliment the other perfectly.

The apocalypse could have restarted then and Sam didn't think he would have been able to find the strength to move. Only when he finally managed to open his eyes did he realise he was stroking Lucifer's feathers, his fingertips brushing over the surprisingly silky texture in slow strokes. He sighed shakily, letting his eyes fall shut as the tiredness began to catch up with him, his head dropping to the side so he could press a soft kiss to Lucifer's forehead.

He had just done possibly the more impure and horrific act known to mankind in having sex with the devil, and yet nothing had ever felt more, quite simply, right.

After managing a grand total of one hour of sleep, Dean came to the abrupt realisation that his concern outweighed his anger. Then again, it always did when it came to Sammy. It was only six AM, but he'd waited long enough so snatched up his phone regardless and scrolled straight to his brother's number under his contact list.

Sitting on the edge of the bed, Dean ran a hand through his hair, a frown of deep concern lining his face as he listened to the ringing of the phone and waited for it to be picked up on the other end.

A/N:

...well. I'm hoping that wasn't too abysmal. I apologize that I'm distinctly lacking in practice at writing sex scenes, a.k.a. probably not very good at it. But yes, Sammy and Lucifer have finally done it. He is now indeed Lucifer's little bitch...

Anyway, thanks for reading and comments of any kind welcome!
