Chapter Text

Lucifer had heard the term, love at first sight. He’d always assumed it was just humans being stupid. They did have a huge capacity for that, after all. 

But the first time he saw Sam Winchester, that assumption went flying out the window. He’d gone to a bar, intending to get well and truly drunk for the first time in millennia to celebrate getting ahold of his vessel, and spotted the hunter off in a corner. 

His first thought? Oh, fuck. Second thought? Yeah, that’s exactly what I want to do with him. 

It would have been easy enough to just lure Sam out of the bar, pin him down somewhere and take what he wanted, but for some reason Lucifer’s stomach turned at the thought. He didn’t want to hurt this guy. That realization almost made him laugh. Maybe he’d gotten soft after his imprisonment. 

Whatever, he decided. He owed Sam for letting him out, he’d make it up to him with a fun night, assuming he wanted one. So he bought a drink, took it over to him, and started to flirt. The hunter was already a bit drunk, and surprisingly enough started flirting right back. 

Soon enough, they were driving back to his vessel’s house. 

“So, what’s your name?” Sam asked on their way upstairs. Then he laughed. “Can’t believe I didn’t ask til now.” 

“Nick. And you’re Sam, right, beautiful?” 

He laughed again. Dammit, that laugh was cute. “You think I’m beautiful?” 

“Would I be doing this if I didn’t?” Lucifer asked, pulling him down for a kiss. 

Sam kissed back, opening his mouth to let him in. If Lucifer thought he’d been hungry for this before, now he was starving. And if the way Sam was tugging at his clothes was any indication, he was too. As they fell into bed together, the Devil’s last coherent thought was, I could get used to this.

Sam woke up naked. It took him a moment to remember why. He rolled over, saw Nick next to him, and smiled. That had been his first drunken hookup in quite a while, and he’d enjoyed it more than he could’ve hoped. The other man’s eyes fluttered open. 

“Morning.” Sam said. 

Nick kissed him on the cheek. “Morning, sweetheart.” 

There was nothing overtly sexy about it, and the simple sweetness of the gesture gave Sam butterflies. They got dressed, and as they headed back downstairs, Nick asked, “Want me to make breakfast?” 

“You don’t have to.” 

“I know.” 

“Uh, sure then. Thank you.” 

So Nick made pancakes and bacon, and Sam set the table, and they ate. 

“This is delicious.” Sam admitted. “I can’t remember the last time I had a homemade breakfast.” 

“Been on the road for a while?” 

He snorted. “Try forever.” 

Hopefully Nick wouldn’t ask too many questions about what he really did. He didn’t want to deal with that conversation right now. He just wanted to enjoy this while it lasted. 

“Dean’s been running you ragged, huh?” 

Sam froze. He hadn’t told this guy about his brother, which meant he was probably either an angel or a demon. Neither was good. He stood up from the table, and . . . couldn’t move. It didn’t hurt like demon paralysis usually did, but he still couldn’t do anything.

The demon sighed. “Aaaand now you want me dead.” 

He stood up and sauntered around the table. “I really thought you’d catch on sooner, sweetheart.” 

“Don’t call me that.” Sam snapped. “What do you want?” 

“Plenty of things. You, some ice cream, the end of the world. Oh, and I may have lied about my name last night.” 

“Yeah, I figured. Demons tend to do that.” Sam said. 

The demon just laughed. “Oh, beautiful, I’m not a demon. I’m an angel, if we’re really getting technical.” 

Sam held down a wave of nausea. “You’re . . .” He didn’t want to finish the sentence, didn’t want to even think about what that meant. 

“Lucifer? Yes, baby, I am.” The Devil stepped in close. “Are you regretting what we did last night?” 

“That’s what you want me for?” Sam demanded, trying to keep the fear out of his voice. 

“A sex toy?” 

Lucifer shrugged. “If that’s what you want to call it. I’m not going to touch you without your consent, Sam, and I’m not going to hurt you either.” 

“Then what are you gonna do?” 

“Keep you here. Pamper you while I destroy the rest of the world.” 

Sam closed his eyes and took a deep breath, trying not to panic. 

C’mon, think, you have to think. There’s no way I can get out of here alive. So I have to do what I can with what I’ve got, which is the fact that he . . . ugh . . . thinks I’m attractive. 

Using his own body as a bargaining chip made him want to scream, cry, or throw up, possibly all three, but it was all he had to work with right now. Sam bit his lip, then opened his eyes and looked at Lucifer. “I want to make you a deal.” 

“And what would that be?” 

“I’ll stay here with you, I won’t fight you, I’ll do whatever crazy, kinky things you want, on one condition.” 

Lucifer raised an eyebrow. “I’m listening.” 

“Never harm the people I love. Dean, Bobby Singer, Jo and Ellen Harvelle, and Castiel the angel. Instead, you protect them.” 

“That’s a short list.” 

“I know.” 

“Alright, beautiful. You’ve got yourself a deal. Hold up your end, or those people are gonna be the first ones I kill.” 

Sam nodded. “I will.” 

Now, hopefully, Dean and the others would have a slightly less tiny chance at winning this. And even if they didn’t . . . at least they’d be alive and not getting tortured. Lucifer stopped paralyzing him. 

“If you want to finish your food, go ahead.” 

Sam shook his head. “I’m not hungry.” 

“Well, I am, so let’s get you back in bed, sweetheart.” 

“Right now?” 

“Only if you feel like it.” 

Sam snorted. “Okay, look. I’m only doing this to keep my friends and family safe. I don’t actually want you, and I never will. You want me, then take me.” 

Lucifer smirked. “Alright. You asked for it.”

Lucifer was pretty sure this was just lust. Like, ninety-eight percent sure. But if it was, he would have relished the way Sam flinched at his kisses and touches. Instead, it made him uneasy. So he stopped, sat back, and handed the hunter his shirt. Sam gave him a baffled look. 

“Are we done?” 

“For now.” 

Sam heaved a sigh of relief, flopping back against the pillows. Lucifer’s emotions twisted in his chest. Was that guilt he was feeling? For fuck’s sake, what was wrong with him? Yeah, it was guilt. He felt bad that he’d upset Sam, bad enough that seeing him shirtless in his bed wasn’t even really that enjoyable. Frustrated, Lucifer got up and left the room. 

What’s happening to me? He was pretty sure he knew. Shit. I’m in love. 

He wanted to make the hunter happy, and he knew that wasn’t going to happen if he kept him here. But no way was he giving Sam up entirely. With a sigh, Lucifer strode back into the room. 

“Sam, c’mere.” 

He did, and Lucifer pressed a hand to his chest for a moment. Sam gave a little gasp. 

“What was that ?” 

“A mark. Now I can find you when I need you. You can leave if you want, go wherever. I’ll come to you.” 

“You’re . . . letting me go?” 

“Yeah. But don’t think this means you’re out of our deal.”

“Gee, thanks.” Sam grumbled. “I just love being covered in magical tracking devices.” 

“You get snarky when you’re mad.” Lucifer observed. “It’s cute.” 

Sam just rolled his eyes and went to grab his bags. 

Chapter Text

Sam sat on a creaky bed in a cheap motel room, head in his hands. Over the last month he’d tried every spell he could think of to remove the mark on his chest, a little starburst-shaped white scar on the opposite side from his antipossession tattoo. Nothing had worked. Of course nothing had worked. Which meant he was stuck being on call to get laid by Satan. 

“Dean’s gonna kill me.” He muttered. “Oh. Oh, no.” 

If Lucifer could track him, that meant he was a danger to anyone around him. Well, even more of a danger than before. He’d known that, but the full implications hadn’t sunk in until now. He was never going to see Dean, Bobby, or any of the others again. 

So he found a place to stay on Oklohoma, got a job at a local bar under the name Keith, and didn’t call them. And sure enough, a few nights later he woke up at midnight to Lucifer in his bed. 

“Hey there, sweetheart.” 

Sam growled in frustration and rolled the Devil over on top of him, locking their mouths together. When they stopped for breath, Lucifer laughed. “Somebody’s impatient.”

“Just shut up and fuck me already.” Sam snapped, panting. 

“My pleasure.” 

That first time wasn’t actually too bad, as long as he didn’t actually think about who he was with. 

And it got easier. He hated that it was getting easier. Sam kept waiting for Lucifer to get bored and start hurting him, but that never happened. He seemed much more interested in figuring out what would get him turned on. So Sam put up with it, kept up his end of the deal. 

And it kept getting easier, feeling better to just let go and let it happen. 

Until one night, hunters came by the bar. They said Bobby had sent them to investigate the demonic omens, the ones he’d told Bobby about himself. He told them no, and they went off to check it out, and Sam didn’t think much more about it. He was just finishing up his shift when one of them burst back in. 

“Oh, hey.”  

“There something you wanna tell me, Sam?” The guy asked. 

“What? No.” He said cautiously. 

“You sure about that?” 

“Uh, yeah. Jeez, are you okay? Where are Reggie and Steve?” 

“Oh, Steve’s good, his guts are laying roasted outside the Holly Five-and-Dime.” 

Sam nodded. “I, I’m sorry.” 

“Sorry don’t cut it, Sam.” 

“Well, what do you want me to say?” 

“The truth.” The other hunter snapped. 

Sam stared at him, confused. What was he talking about? Did he know about Ruby, or Lucifer? 

“Okay, I’ll give you some of my own, then. We went into town, captured ourselves a demon, and we got jumped by ten more. Steve bought it.” 

“I’m sorry.” 

“Saying it twice don’t make it so, Sam. See, this demon, he told us things, crazy things. Things about you.” 

Sounded like he did know, at least some of it. Shit. 

“Demons lie.” Sam said flatly. 

“Yeah? I’m gonna ask you one last time, Sam. The truth. Now.” 

Reggie burst into the bar, holding a knife to the throat of a struggling woman. His coworker, the one who’d kept trying to talk to him, Sam remembered. 

“Lindsey!” 

“So, are you gonna tell us about what you did? I want to hear you say it.” 

“What, how he let me out?” Lucifer asked from behind them. The knife flew out of Reggie’s hand and swooped in a figure eight around the hunters’ heads before embedding itself in the dartboard. “How he’s all mine now?” With a flick of his hand, he slammed the other hunters up against the wall. “How I’m going to kill you both for threatening him?” 

Lindsey was frozen, cowering against the bar. Sam helped her out the door. 

“Who is that guy?” She demanded. “What’s going on?”

“It’s complicated. Go, you’ll be safer that way.” 

He dashed back into the bar to see Lucifer grinning, just starting to twist the other men’s heads at a painful angle. 

“Let them go!” 

“Why?” 

“Luce, please.” 

The Devil sighed. “Well, you’re no fun. Fine.” 

He released his grip on the other hunters. They crumpled to the floor, gasping for breath. 

“My sweetheart here thinks I should let you two live for some reason, so you have a count of five to get your sorry asses out of here intact.” Lucifer said in a bored tone. “One . . . two . . . three . . . four . . .” 

They ran. 

Sam turned to the other man. “Thanks, I guess.”

“You’re very welcome.” 

Lucifer touched him differently that night. Gentler, softer, whispering pet names in his ear. If Sam hadn’t known better, he’d have said the Devil was being . . . loving. He didn’t want it to be over. He hated himself for that, but it was the truth. So when Lucifer was about to leave, Sam wrapped his arms around him and muttered, “Stay.” 

“What’s that, sweetheart?” 

“Stay with me.” Sam repeated, blushing. “Please.” 

Lucifer kissed his cheek. “Alright. I’ll stay.” 

“Beautiful, can I ask you something?” 

“What?” Sam said through a yawn. 

It was somewhere around dawn, and Lucifer had just woken him with a few well-placed kisses. 

“As fun as all this has been, I’m going to need you for something else soon.” 

“Which is?”

“A vessel, Sam. My vessel.” 

Well, he was definitely awake now. Adrenaline and everything. He rolled over to face the Devil. 

“First of all, you’ve got one already, second of all no. You can do whatever you want with me, except that.” 

“You’ve already given me your body. I really don’t see how this is any different.” 

“Well, it is. I’m not letting you possess me.” 

“You’re so stubborn.” Lucifer said fondly, tracing a hand through Sam’s hair. “Alright then. I can wait til you’re ready to let me in.” 

“Which is never.” 

He just laughed. “Sure, baby.” 

Then he vanished.

“We’re better off apart. We’ve got a better chance of dodging Lucifer, and Michael, and this whole damn thing, if we just go our own ways.” 

Sam held back tears. He’d finally swallowed his pride and called Dean for help, and this was what he got?

“Dean, don’t do this.” 

“Bye, Sam.” 

His brother hung up. 

“Well look at that. He gave up on you.” 

Sam turned to see Lucifer sitting in the passenger seat. “Shut up.” 

“Oh, don’t be like that, you know I’m right.” 

Sanm took a deep breath, clenched his jaw, and finally said, “I want out of the deal. I’m not yours anymore, you don’t protect Dean.” 

“Why?” 

“Because I’m done playing your stupid games. Kill me if you want to, but I’m going to fight you with everything I have.” 

“Oh, sweetheart, I’m not going to kill you. You’re too important. But if you want out of our little arrangement, then fine. You know what?” Lucifer pressed his hand to Sam’s chest. “I’ll even give you a fighting chance. My mark’s gone, after I leave here I won’t be able to find you.” 

Sam nodded. “Alright.” 

He didn’t know why the Devil was agreeing to this, but he also didn’t really want to know. It was a chance, and he’d make the most of it. “Bye, then.” 

“Bye, Sam.” Lucifer said, kissing his cheek. “Love you.” 

And then he was gone. Sam checked his chest as best he could while driving, and sure enough, the mark was gone too. This should have felt like a victory, but instead all he wanted to do was cry. 

Then Dean called again, apologizing, saying he wanted to meet back up. So Sam came, and was relieved to find his brother was back to his usual self, at least as much as he ever was now. They were a team again, and he hoped it would last. He hoped he could forget about what had happened with Lucifer, too. 

Chapter Text

Sam checked the date on his phone and sighed in exasperation. His cycle had never been especially regular, but it had been two months since his last period. Either sleeping with the Devil had messed that up somehow, or . . . no. No, it had to be the first explanation. 

His body had always been a bit confusing to him. His Dad hadn’t exactly been the type to be open-minded about gender: Sam had a mostly male body, he was a guy, end of discussion. He hadn’t minded. He’d always felt decidedly male anyhow. He knew the very basics of how pregnancy and everything worked, he wasn’t an idiot, and he’d been with enough men to know that it might happen to him. But that couldn’t be what was happening now, no way. 

“Whatcha doing?” 

Sam whirled around to see Dean giving him a weird look. 

“Easy there. You look like I caught you watching porn or something.” His brother said, laughing. 

“It’s not that.” Sam paused, gathering his nerve. “Dean, can I tell you something?” 

“Yeah, what?” 

He adjusted his jacket with shaky hands. “After we split up, when I ran into Lucifer? He, uh, well . . . he didn’t just talk to me.” 

“Meaning?” 

“We had sex.” 

Dean’s eyebrows went up. “Sorry, what? Man, I thought you’d learned your lesson about banging demons.” 

Sam looked away, blushing furiously. “I didn’t exactly have much choice, Dean!” 

Dean’s face went from his earlier annoyed expression to shock, then finally rage. “You’re saying he, he forced you?!” 

“More like blackmailed me into saying yes.” Sam mumbled. 

“Same difference, I’m still gonna rip his eyes out and make him eat them!!” Dean yelled, stomping around the room. 

“Dean, hey, calm down. We gotta focus on what we’re hunting right now, okay?” 

Dean looked up at him, and Sam was surprised to see tears in his brother’s eyes. “Sammy, I should’ve stopped him. I should’ve kept you safe, dammit!” 

“Okay, no. You are not blaming yourself for this. It’s Lucifer’s fault. Not yours, not mine. That’s not even why I told you.” 

“Why’d you tell me, then?” he asked. 

“Cause I think I might be pregnant.”

“You mean you think the Devil knocked you up?” 

Sam sighed. “Yeah, maybe. I’ll take a test as soon as we finish up this hunt, okay?” 

“So, what, we’ve got a half-demon kid on our hands?” Dean said as they left the ramshackle house. 

Sam shrugged. “That’s what it looks like. It would explain how Jesse’s able to unknowingly warp reality. So what do we do?” 

“We need help.” Dean said. 

When they got back to the motel room, Cas was there waiting for them. 

“I take it you got our message?” Sam asked. 

“It’s lucky you found the boy.” 

“Yeah, lucky, great.” Dean said. “Now what do we do with him?” 

“Kill him.” 

Sam froze. He opened his mouth to say something, anything, but the words wouldn’t come out. 

“Cas!” Dean snapped. 

The angel just glared at them. “This child is half demon and half human, but he’s far more powerful than either. Other cultures call this hybrid cambion or catego. You know him as the Antichrist.” 

“I don’t get it, Jesse is the Devil’s son?” Sam asked, once he’d gotten his voice back. 

“No, of course not. Your bible gets more wrong than it does right. The Antichrist is not the Devil’s child, it’s just demon spawn. But it is one of the Devil’s greatest weapons in the war against Heaven.” 

Sam couldn’t help flinching. He might have one of those “weapons” in his uterus right now. 

“Well if Jesse’s a demonic Howitzer, then what the hell’s he doing in Nebraska?” Dean demanded.

“The demons lost him.” Castiel said. “They can’t find him, but they’re looking.” 

“And they lost him because . . .” 

“Because of the child’s power. It hides him from both angels and demons. For now.” 

“So he’s got like, a force field around him? Well that’s great, problem solved.” 

Cas sighed. “With Lucifer risen, this child grows strong. Soon he will do more than just make a few toys come to life. Something that will draw the demons to him. The demons will find this child. Lucifer will twist the boy to his purpose, and then with a word, this child will destroy the host of Heaven.” 

“Hold on.” Sam said, standing up. “We’re the good guys, we don’t just kill children.” 

Castiel stood up too, glaring at him. “A year ago, you would have done whatever it took to win this war.” 

“Things. Change.” 

Dean stepped in between them, breaking the tension. “Hey, look, we are not going to kill him, alright? But we can’t leave Jesse here either, we know that. We’ll take him to Bobby’s, he’ll know what to do.” 

“You’ll kidnap him.” Cas said flatly. 

Dean nodded. The angel didn’t look remotely convinced. “What’s going on in this town, is what happens when this thing is happy. You cannot imagine what it will do when it’s angry. Besides, how will you hold him? With a thought he could be halfway around the world.” 

“So we tell him the truth.” Sam said firmly, shouldering his way past Dean. “You say Jesse’s destined to go darkside, fine, but he hasn’t yet. So if we lay it all out for him, what he is, the apocalypse, everything, he might make the right choice.” 

At this point, he wasn’t sure if he was arguing this for Jesse or for the baby he might be carrying.

Castiel got in his face. “ You didn’t. And I can’t take that chance.” 

Then he vanished with a flap of wings. 

“Dammit.” Sam said. 

The word didn’t really seem adequate. 

They walked down the front steps of Jesse’s house. Sam was still a bit surprised that Jesse had left. He couldn’t really blame him, though. He wanted to go find the kid, but he knew there was no way they could. Castiel turned, about to leave. 

“Cas, wait.” Sam blurted out. 

“What?” 

“I think . . . I think I might be pregnant. With another Antichrist, I mean. Is there a way you can get rid of it?” 

He wanted to keep his baby, wanted it more than anything. But if they were going to be in this much danger, it might be better not to. Easier to lose them now than once he’d gotten to know them. 

The angel’s eyes widened. “I’ll try.” He said, finally. 

He walked up to Sam and reached up to put a cool, callused hand against his forehead. They both started to glow, until Castiel gasped and yanked his hand away. 

“You’re with child, but I can’t remove it. I doubt your human abortion methods will work either.” 

Sam nodded. “Okay.” 

The response was more automatic than anything, he was in shock.

Cas paused. “I won’t try to kill your child, Sam. Just promise me you won’t let Lucifer take them back.” 

His mind was still reeling from the angel’s words, but Sam managed to nod again. “I’ll keep them safe. I promise. Whatever it takes.”
