Lucifer's throat muscles pulled Dan to new highs. Slick swallowing heat drew him out, fast. Perfectly symmetrical matte black lines above and below his stupidly long lashes reminded Dan of the women he'd been with. Stubble scratching where it pressed through his pubes on the down stroke aggressively upended any feminine similarities.

Fuck he was good at this. Dan heard himself making sounds, Lucifer humming around his dick in counterpoint.

A bit of saliva escaped wicked lips, hot running to cool when it hit air, dripping. A strong thumb joined Lucifer's lips, stroking down his shaft to balls, holding near the base, in exquisite tension. Dan's borrowed jeans pushed down his legs made an uncomfortable ridge that urged him to keep his hips up.

The Devil took him deeply, throat open. Dan grabbed at anything, gripping blankets. Hot tongue squeezed the tip of his cock to the roof of his mouth.

"Fuck!"

Dan felt and watched lips curl up around him, black eyes flicking up, and it was his undoing. Deep lower pounding tightness pushed and released in a pulsing rush. dripping where Lucifer didn't quite swallow all it down like a man searching for the bottom of a milkshake with a straw. His lower abs contracted in spams, curling him up in degrees.

Dan lay back awash in numbing warmth, vaguely aware of the bit of mess sliding down his stimulated, twitching cock.

Lucifer got a kick out of tossing him down like a rag doll. Not that he was complaining.

Someone-anyone, as an audience gave him goosebumps. Chloe peeked out from around the corner of her bathroom doorway, having issues getting her lipstick on cleanly, clutching a tube in a one-handed death grip.

He got the feeling she hadn't moved from the mirror since Lucifer shoved his jeans down. Was she thinking about the couple of times he jacked off while she watched? She hadn't been in the mood, simply enjoying holding his unoccupied hand but otherwise not participating.

He stretched, heartbeat receding from his ears. Lucifer withdrew, cat-smiling, absently wiping his mouth.

Chloe, sans lipstick tube, came up behind Lucifer, fabric on fabric arms sliding up his chest. She kissed him on the back of his neck. From his angle, her lips left a blush of red near his jawline. Dan was sure he heard a purr.

"Hello, darling, have you changed your mind?" He hadn't moved from where he now stood at the end of the bed.

Her voice pitched low. "I'm starting to think maybe Trixie missed her bus and we had to drive her to school."

Dan, mid-jean tug, halted. It'd been a long time since he'd heard that one. He got the boxers back up at least.

Confusion lay painted all over Lucifer's face. "That is by far, the strangest version of a come-on I've ever heard."

Chloe, ever-patient, moved her hands the other direction to rest in his front trouser pockets. "What I'm saying is, there are a couple of good reasons We could be late this morning." Dan followed her motions, down to tenting fabric of Lucifer's slacks.

Dan's brain hitched at 'we.'

"Yes, but-"

Her fingertips moved inward within their confines. "Lucifer, honey, 'morning sex' is not something you can give Pierce as a valid reason for being late to work."

Lucifer's face distinctly pinched. "There's something I should tell you about Pierce, now that you mention it."

Chloe's fingers kept moving. "Can it wait?"

"He certainly has. I don't see why not, especially if you're suggesting what I think you're suggesting."

She lipped his earlobe. "What do you think I'm suggesting?"

Lucifer turned to kiss her. She wrinkled her nose but didn't pull back. It registered to Dan that the smell of his satisfaction still clung to his lips. Chloe kissed him anyway, but not deeply. Still, things began stirring around with the visual.

"I think you're suggesting we have a Chloe sandwich wherein my manhood does glorious things to your inner lady bits while Dan does presumably acceptable things with his face to your outer lady bits."

Dan was quite sure his own equipment attempted to make a valiant recovery.

Gah. He hesitated to interrupt, but a sense of impending doom crept up his craw. "What about Pierce?"

Lucifer huffed. "He and I have a long history. Not so much together, but I've known him for ages."

The impact of his choice of terms sank to to them both. Chloe withdrew her hands and stepped back. "Please tell me you're not saying what I think you're saying."

Dan crossed his legs on the bed. "How long a history?"

Lucifer sighed. "I'm not sure it's a good idea to dump this on you so quickly, on top of everything else."

Whatever it was, he hoped it wasn't as earth-altering as everything else. I mean, Pierce had been working with them for a while now. If it was a big deal, Lucifer would have said something, right? "Another angel sibling?"

"If only. Those I can deal with."

Chloe sat on the bed near Dan. "Lucifer."

"Can you promise it won't affect your working relationship?"

"Meaning?"

"He can't know you know."

Dan got annoyed. "Why not?" He wracked his brain for anything regarding Biblical Lucifer he Googled recently. It wasn't much. Wait, is he a universal Satan? From other religions? Shit.

Chloe met Dan's eyes, turned back. "You would have said if he's a demon, right? That's not it?"

Lucifer did not like this. "I'm afraid if I continue, you both will have to call in a personal day."

Dan frowned. "What could be heavier knowledge than you being the Devil?" A horrible thought came to him. "Wait, he's not God, is he?"

"Good grief, no." He barked a laugh, then sobered.

Dan felt both relief and a little embarrassed.

Lucifer continued, less happily. "But he's almost as old as the not-so-metaphorical Eden."

Shit. There's a Garden of Eden. Because of course, there is. He tried to shut down his brain before it went much further with that line of thought. Noah? No, stop, Dan. Focus. "There's an Eden?"

"Was. Lovely creation. The famed Hanging Gardens didn't come close."

Chloe straightened, undeterred. "Who is he then?"

Lucifer turned away, reluctance written in his posture. "Cain."

"Cain? Cain from the Bible Cain? Please tell me it's not literal."

Dan's brain echoed the sentiment, where it wasn't freezing up and rolling over itself.

"After he murdered his brother, Dad marked him, permanently. He can't die, but he wants to."

His brain re-engaged. "God rewarded him with eternal life?" That didn't make sense. Sure, like anything else up to this point from last freaking Friday makes sense.

Lucifer frowned, as if it was a stupid question. "Rewarded? Hardly."

"But he can't be killed?"

"Oh, you misunderstand. He can be killed. The sodding bastard just won't stay dead. Like a bloody classic vampire but none of the tricks for destroying one works." The vehemence in Lucifer's voice gave Dan the impression that theory had already been tested.

"Like DeadPool?"

No, he was wrong. The look Lucifer gave him was distinctly less tolerant than the 'rewarding' question.

Chloe got up. "Why is he here? And a Lieutenant?"

"See, I told you this is going to take all day."

Dan joined her. "I think we have a right to know."

"It's not like he's dangerous."

"A cursed murderer who can't die isn't dangerous?" Why do I feel like I'm asking questions that are both perfectly reasonable and unbelievably dumb at the same time?

"Not to you. He came here because of me." Lucifer bit out the next part. "And to use Chloe's special status. He thinks since I'm vulnerable around her, he might be too. He wants to die."

Chloe's hackles raised. "You still have to explain what makes me 'special' around you."

Dan blinked. "So, when did I become part of a murder plot? What is he trying to do with Chloe?"

"Nothing. Neither of us were willing to let her wander into danger just so he can die."

Chloe eyed him. "I don't know if I should be angry or not. Does Amenadiel have the same problem around me?"

"Actually, no."

"There you go. Now we don't have to worry about me, and you let us in on what you're going to do with him."

"Well, we started with a chainsaw. Didn't take."

Dan groaned. "No, why are you helping him? Have you considered what might happen if you do manage to kill him and the police find you hovering over his dead body? Have you envisioned the shit storm that would ensue if we didn't already know who you are? Let alone Pierce?"

"I figured I'd cross that bridge when I came to it. All efforts have been unsuccessful thus far."

Chloe's jaw clenched. "Lucifer, we really need to discuss your complete inability to plan for the future."

He cut in, "So, Cain is our boss. Great. Does he actually have a professional background in police work?"

"No idea. Your chain of command put him there. Admittedly he wheedled himself into the position, but he was already a police officer of some kind, I'm assuming, or he wouldn't have gotten this far."

Chloe had that 'about to pull her hair out' look. "Okay. Everything we've seen of him says he knows what he's doing as a Lieutenant. So, knowing work is still work, let's just go in, have a normal day, and re-visit this later. Unless there are any other immortal beings or other creatures at the station we should know about." She squinted. "Are there?"

"None that have revealed themselves to me. I didn't even know Cain was Cain until I saw his mark and stabbed him."

It wasn't nine a.m. and Dan was already out of spoons.

Lucifer cocked his head. "Why do I get the depressing feeling no one is in the mood for morning sexy time anymore?"

Dan drove separately. He considered swinging back by his place for his own clothes, but the extra events of the morning made another stop impossible. At least he still had his regular hoodie. And Lucifer had hair gel at Chloe's that didn't smell like fruit.

He jogged down the stairs into the precinct. The Lieutenant looked unhappy, as always. It reminded him unfortunately of a blond vampire. He angled for a detour around, but Pierce stopped him on the floor. "You're late. Why didn't you call?"

"...Trixie missed her bus."

"I thought Decker had your kid at her place."

Oops. "Chloe's car is in the shop. So I came over. And helped."

"Either of you hear about a bit of technology called Uber? Throw the kid in a car and call it day."

"Okay, I'm here, sorry, do you need something? Or can I get started?"

"I know you came here Saturday, but that's not an excuse to not be here on time today. Don't make a habit of it. And don't try to avoid me. Be an adult and give us a heads up."

Dan's jaw tightened, but Cain wasn't entirely wrong about being late. "Right, no problem."

"It's not my place to comment, but you might want to steer clear of Lucifer outside of office hours. The guy is a loose cannon. Plus, he's dating your ex. No reason to give him more of your brain space than you have to." 'Marcus' seemed to be trying to give him a meaningful look.

Hoo boy. Lucifer's eyes over his dick came back to him. "Yeah, okay. Sure."

"I can keep his and Decker's cases away from your work."

"No, it's fine. Everything is perfectly fine." Dan threw in a thumbs up for good measure. "We work fine together." Stop saying 'fine'.

"I think I see what's going on."

"Uh?"

"You're still protective of her. I mean, she is dating a guy who has to be on some kind of medication, right? Who on earth would have any kind of extended relationship with someone who calls himself the Devil, am I right?"

How did these things happen to me?

"I mean, he's been a valuable part of the workforce here, if eccentric. She knows what she's doing?"

"Are you defending him? Seriously? I know you and Decker split, but I thought you'd be a little more…"

"What?"

"Not okay with it."

I am not okay with you. "I think I'll just get to work, if you don't mind."

—-

Dan tapped the door of Ella's lab. He'd officially had enough paranormal encounters for the day. Some case work should help him take his mind off everything. "Hey, how's our favorite Forensic Scientist today?"

Ella jumped. "Hey Dan." Her hair was a little messy and she looked tired. Her shirt of the day was pale pink with a squat, rounded creature in the middle. The caption read, 'I am a tiny foxtato, and I believe in you, YOU CAN DO THE THING.'

He came in. "You okay, buddy?"

"I'm a little out of it. I didn't sleep great and I think I need more caffeine. The Mondays or something. You look chipper."

Dan swallowed and shrugged. "I got a lot of sleep this weekend."

Ella grinned slyly. "Oh? where did all this sleeping happen?"

He ran slow this morning, apparently. "Uh. Here and there."

She ran her eyes down him. "I see. Are those new jeans? They look a little long on you."

"Dammit, Ella. I just got here. Don't make me go home and change."

"Why, you weren't home this morning?"

"This is what I get for having observant friends. How about I bring you a coffee and you turn your powers for good on this case instead of on my wardrobe?"

"It's a deal. Quad americano, sugar, no cream."

"Station coffee?", he asked hopefully.

"Not if you know what's good for you."

"Starbucks run, got it." Dan sighed.

Chloe tapped in several minutes later. "Hey Ella."

"Hey, Dan is coming back with coffee, and then I can be functional. Did Lucifer come in with you or Dan?"

"Me, wait-"

"Gotcha."

"Are you sure you're not awake?"

"I have energy for exactly one thing right now. Juicy gossip. And I need another person to help me go over my notes from yesterday, because I'm not making sense to myself."

"You came in to work yesterday?"

"Yeah, it was nice out and I just felt like double checking something. You know when you get an idea in your head and it won't go away until you deal with it?"

"Sure."

"I took another look at some of the evidence in the murder case, but my notes don't make any sense this morning."

"What did you find?"

Ella groaned. "Coffee first? Where's Luci?"

The Devil appeared, planting a kiss on the back of Chloe's head. "You seem to be in my way, Detective."

Chloe, who had been standing with her hands spanning the door frame and door, threw a grin over her shoulder. "Oh?"

Lucifer wrapped his arms around her waist, lifting her a few inches off her feet, and swung her around and out the door. "There we are." He stepped inside the lab. "Good morning, Ella."

She hopped up out of her chair and hugged him.

"You're going to do this every time I see you, aren't you?"

"Yup."

Lucifer sighed. "So, Dan said you have some new evidence to go over."

"Is he back yet?"

"He's on his way back."

Ella gathered her notes. "Okay, give me a minute to round up my stuff." She pulled a stack of sorted bags out a locker. "Did you have a good weekend?"

"Why, yes, as a matter of fact-"

Chloe broke in. "It was good. We had a good weekend. Lots of sleep. Lots of, uhm, quiet time." She nodded.

Ella poked her in the ribs. "That's what Dan said. Caught up on sleep."

Lucifer glanced over the evidence bags. "Well, they did. Conked out for a solid half-day each."

Chloe groaned. "Lucifer, what did I say a few days ago?"

"You said not to talk to anyone else about our experimental relationship. Ella already inferred everything."

"It's cool, guys, I like to listen to gossip, but I don't share it. Much. How's Dan working out?"

Chloe blushed.

"I'll take that as a leaning 'good'."

Lucifer echoed her grin. "He has his positive points. He's much more tolerable when he's not so worked up. Just needs to release a little tension now and then." He glanced back. "Speak of the Dan!"

A tray of drinks preceded Dan, who had a bag of goodies. "Behold, your king of breakfast. Ella, yours is the one marked 'Leia'. Lucifer, yours is 'Satan', naturally. Chloe - look for 'Kyle' and mine's the last one. There's lemon bars in the bag."

Chloe pulled her cup out of the tray. "Did they at least get your name right?"

"Apparently, at this location, I'm 'Dean'."

"Funny, you don't look anything like a Winchester."

Ella gleefully took a long, slow sip, her eyes blissfully closed. "That is much better."

"Thank Satan, he slipped me a twenty." Dan finally got a look at her shirt of the day. It was a cartoon of a rounded fox thing.

She leaned up and pecked Lucifer on the cheek. "Thanks, Satan. Mmmm. prickly.

Okay, so, I discovered a few things. One, Claire hasn't been heard from, which shouldn't be that big of a deal, but we haven't found any other information about her. The officers who picked up the computer lab after you guys left said the place was empty."

Ella sorted through her bags. "The other, is this thing." She handed the bag to Chloe, which contained a double-bagged claw. Or it kind of looked like a claw. "I can't figure out what it is, except that it's organic, probably, and it's making my brain hurt."

Lucifer stiffened and reached for it. "Naamah."
