Nathaniel/Sebastian at Mountaintop

 (Grapefruit-level NSFW; will eventually be part of OWC)

Sebastian went to Mountaintop and made a beeline for Nathaniel's office. He went in, locked the door, and drew the blinds, then turned to face a very nonplussed Nathaniel.

"This is a really bad time, Sebastian," he began, but Sebastian was already kneeling in front of him. Nathaniel cringed. "Seriously, I wouldn't--"

Sebastian ignored him and worked at his fly. Nathaniel squirmed uncomfortably, trying to pull away without ruining his clothes, and with good reason: The instant Sebastian had Nathaniel's dick out, Nathaniel lost control of his bladder. He closed his eyes, blushing deeply.

Sebastian was unconcerned with the heavy, warm stream dampening his hair and soaking through his clothes. He pulled on a disposable glove, rubbed lubricant from a small tube onto two of his fingers, and stuffed those fingers inside Nathaniel, massaging his prostate. 

Nathaniel cried out, eyes flying open in shock! Sebastian was into this? Seemingly so: With his free hand, Sebastian was slowly taking off his own clothes, an intimate little smile on his face. He pulled his fingers out and disposed of that glove the second the stream stopped, and then he pulled his shirt the rest of the way off. He slid a flavored condom onto Nathaniel's rock-hard member and gave him a few teasing licks-- why was Nathaniel letting him do this? It was so humiliating, and at his place of work!-- then started sucking him in earnest. Nathaniel ran his hand through Sebastian's wet hair without thinking.

"Why are you doing this?" he murmured, not really expecting an answer. Fuck, this felt good! He knew Sebastian knew how to give head, but this was.... He couldn't even try not to enjoy it! He held Sebastian's head in place while fucking his pretty mouth, but when he started shaking in pleasure, Sebastian somehow managed to duck away.

Sebastian stood, slowly, gazing into Nathaniel's sky-blue eyes. Nathaniel stared back, completely hypnotized.

"Do you want to fuck me, Nathaniel?" Sebastian asked, turning his back to the other and bending over his desk. Nathaniel blushed; he couldn't help that his gaze traveled to Sebastian's incredibly well-formed ass. Sebastian moaned as Nathaniel cupped his cheeks and kneaded gently-- then a scream escaped him as Nathaniel shoved into him unceremoniously!

Nathaniel set a hard, fast, vicious pace, as if to get revenge on Sebastian for violating his privacy and humiliating him. He reached into his desk drawer and scrabbled around a bit till he found the vibrating cock ring Trent had given him, slid it tightly onto Sebastian, and turned it on. Then he grabbed a ruler and sat back into his chair, pulling Sebastian with him so Sebastian was sitting in his lap. They adjusted their position so that Sebastian's legs were draped over either chair arm and his dick and balls were completely exposed. He was straining against the pressure of the cock ring, which Nathaniel, sadistic, sexy, wonderful Nathaniel, had turned to the highest possible setting.

Sebastian was breathing hard as he writhed against Nathaniel, head back against the taller man's shoulder. Nathaniel was full of surprises, it seemed-- and the thought had just barely finished crossing his mind when the first strike came. Sebastian cried out and arched against Nathaniel, and promptly felt the ruler hit the head of his cock again.

"More," he mewled, large teal eyes pleading.

Nathaniel obliged him, this time mauling Sebastian's balls while smacking his cock with the ruler. 

"I like the way you tighten when I hurt you," Nathaniel whispered in his ear. Sebastian responded by squeezing around him deliberately, as hard as possible, while riding him within the short range that he could.

"FUCK, Sebastian!" Nathaniel cried out. Sebastian chortled low in his throat and repeated the motion; Nathaniel squeezed Sebastian's balls as hard as he could in retaliation. Sebastian's stomach clenched as he cried out. He screamed louder as Nathaniel hit him again.

"That's so good, Nathaniel, so fucking good!" he wailed. "Again, please, hit me again!"

Nathaniel hadn't needed to be asked. He kept up a steady pattern of strikes, some harder than others. When Sebastian was little more than a broken, mewling mess in his lap, Nathaniel gave his balls an extra-hard squeeze before smacking them with the ruler, too!

"Let me cum, Nathaniel, please, I can't take it anymore!"

Nathaniel chuckled and shook his head, though he kissed and then gently bit Sebastian's neck. Sebastian squirmed; he liked it better when Xander bit him, but that was still an erogenous zone. His breathing was shallow; he could feel he was close to blacking out from the mix of sensations.

Nathaniel sensed it, too. He set the ruler down and stopped moving, just holding Sebastian against him and letting him calm down. Sebastian impatiently tried to ride him, but Nathaniel held him still until Sebastian let out a snarl of frustration.

"I hate you!" he snapped.

"Clearly," Nathaniel responded dryly. "But you like being hit, and teased, and pissed on... and you really like being fucked, don't you? Needy little cum-dumpster."

Sebastian gave a faint little laugh. "So do you. Don't forget, I've seen how you are with George and with Trent, my Trent."

"Your Trent?" Nathaniel echoed. "You should be begging him for dick right now, not me."

"He's with Rebecca right now."

"Shocker."

Sebastian reached up a hand and slapped Nathaniel's face. Nathaniel thrust up into him in response; he liked that. Sebastian slapped him again. Nathaniel moaned, then picked Sebastian up and maneuvered them to the floor.

"On my back," Sebastian said. "Otherwise--"

"If you're afraid of calling me by his name, I can just gag you."

"Put me on my back and choke me." Sebastian was blushing slightly; it was risky, asking Nathaniel to fuck him the way Nathaniel liked to be fucked; it was too intimate, and neither of them could afford to fall for the other. So he was surprised when Nathaniel obliged him.

"Do you have a safeword?"

"You're asking that now!?"

"You're the one who barged in here!"

"Okay, that's fair. I'll tell you next time," Sebastian said with a wink. Nathaniel's hand tightened on his throat.

"There's not going to be a next time," he said flatly.

"Suit yourself. It's Slim Jim."

Nathaniel's brow creased as he eased up. "Seriously?"

"Hey, I had to set it up with Maze for my side hustle. It was the first thing that came to mind. Why, what's yours?" Sebastian challenged.

Nathaniel smirked. "I don't have one."

Sebastian scoffed. "Right. The finger snaps. I'll do the same if I need you to stop."

Nathaniel smiled, almost tenderly, and pressed his body down against Sebastian's to kiss him. Sebastian kissed back, running his fingers through Nathaniel's short, spiky hair. This was nice; Sebastian didn't normally kiss during sex, not even Lucifer. Before and after, maybe, but not while Lucifer was inside him. That was something he had only wanted to do with Trent. But somehow, letting Nathaniel kiss him while they were fucking seemed natural.

As if reading his mind, Nathaniel chuckled when he pulled back. "I thought hookers didn't kiss during sex."

"I'm not charging you for this," Sebastian said, his voice frosty as he promptly shut down whatever he had just been feeling. He swallowed and looked away. "Like you said, I'm the one who barged in here. So you might as well just get off and get on with your day, then."

Nathaniel paused. Had he hurt Sebastian's feelings with that joke?

"Hey... I don't have a problem with you doing your thing," he said gently, stroking Sebastian's cheek. "I was just surprised you let me kiss you." He started to pull out, but Sebastian wrapped a leg around him.

"We don't have to stop. I'm fine." After another pause, Sebastian repeated, "I'm fine," and pulled Nathaniel down for another kiss. He didn't know if he was-- he was feeling something that he didn't want to explore-- but equally, he didn't want this to stop. Nathaniel was amazing in bed, he'd taken all this in stride rather than throwing Sebastian out on his ass or calling the cops, and if Nathaniel was serious about not wanting there to be a next time, Sebastian was going to make the most of this. He loved the way Nathaniel used his body, the way he experimented, things he did just to get a reaction. He was completely melting into the sensations, kissing Nathaniel again and again, enjoying how it felt when they tangled their fingers in each other's hair and held each other so close-- when Nathaniel suddenly picked up the pace, grinding hard against Sebastian's sweet spot, making him writhe in pleasure and the pain of not being able to release! He cried out Nathaniel's name until Nathaniel choked him too hard to speak, and he felt the other man shudder against him and then go still.

Nathaniel lay on top of Sebastian, coming down from a shockingly intense orgasm, dazed and disoriented for a good couple of minutes before he remembered his partner. He pulled out-- eliciting a needy little groan from Sebastian-- and disposed of the condom, then kissed his way down Sebastian's slender body. Using a bit of lubricant, he gently eased the cock ring off, then wrapped his mouth around Sebastian's nearly-purple head. Sebastian's fingers clenched into the carpet as he came instantly, then blacked out.

--

When he woke up, he was at Lux, in the penthouse, in bed. He was completely clean and dry... and alone. He sat up, rubbing his eyes, and checked the bedside tables for any notes or hints that he'd been anything other than dreaming. Then he checked his phone, which was plugged in and fully charged.

Nothing.

He wished Nate's office was still bugged so he could see for himself if he'd actually gone and had sex with Nathaniel, or if he had just dreamed the whole thing. He decided to send a text.

I just had the craziest dream.

He set the phone down and waited. No response. What could that mean? He and Nathaniel hadn't been on the best of terms, so if it hadn't happened, Nathaniel would either ignore him or tell him to go fuck himself. If it had happened, Nathaniel probably wouldn't want to acknowledge it, so he would definitely ignore him. Sebastian didn't like this uncertainty. Why did he care if it was real, anyway?

--

Downstairs, Nathaniel scoffed at the text he'd just received and went back to nursing his drink.

"Thanks for coming to get us," he said a little sheepishly.

"Of course." Lucifer was as genial as ever, smiling as he topped Nathaniel off.

"I don't understand... what happened," Nathaniel said haltingly. "Sebastian and I don't get along. He hates me because of things with Trent, and then all of a sudden he comes storming into my office right when I'm about to take a break." His face reddened at the memory.

"He was curious about you," Lucifer said. "It's only natural, you know, to wonder about your lover's other lovers."

Nathaniel looked at him. "Are you curious about Trent?"

"I am. He is, unfortunately, not interested."

"That doesn't bother you?"

Lucifer had to think about that. Did it bother him that someone he was curious about wasn't attracted to him? Perhaps at one time, it would have. For eons, he had been used to having anyone he wanted, without even needing to snap his fingers. The first person who had ever been uninterested in him had been Chloe. They had had a slow-burn romance, but she had ultimately left him to find herself, or so she said.

There were some vague similarities, Maze had pointed out, between Chloe and Sebastian. Both were curly-haired blondes, for a start-- yes, he had to admit, he may have a bit of a type-- both intelligent, both forces of nature when they wanted to be. Chloe had had a past, with her ex-husband, Dan; Sebastian was more than a little obsessed romantically with his friend Trent. Yet while Chloe had avoided showing vulnerability to Lucifer and had shut him down time and again, Sebastian had come to him open and emotional, needing him, first for a night and then for more. He and Chloe had met by chance and she hadn't believed him when he told her, point blank, who he was; Sebastian had sought him out and accidentally provoked him into revealing himself, and wore his feather with pride. Chloe had all but begged Lucifer to tell her he loved her; Lucifer had wasted no time in telling Sebastian how he felt the moment he first felt it-- which, yes, had been when they were in bed together. Sebastian had seemed to take it with a grain of salt, even having known that Lucifer refused to lie.

Did it bother him that the person Sebastian continued to love, despite their relationship, didn't want to sleep with Lucifer? It was... possible.

"He's the second person to turn me down," Lucifer answered, a bit distractedly.

Nathaniel's gaze intensified. "Trent is?" he asked softly.

Lucifer frowned. "Trent?"

"You said he's the second person to turn you down. But before that, you kind of went somewhere for a moment."

Lucifer blinked, then led Nathaniel to the couch to sit with him. "Yes... Trent is the second person to refuse sex with me, but it doesn't bother me as much as it would have a few years ago." He sipped his own drink. "I had a girlfriend before Sebastian," he confided.

"Detective Decker. You mentioned her at the police station."

Lucifer was impressed. "Good memory! Yes, well, she and I had been broken up less than a week before Sebastian approached me. Maze has been pointing out increasingly disturbing parallels between the two of them, and she suggested Sebastian might walk out on me now he's found himself a vampire to bond to. Perhaps that's my type. Perhaps I'm punishing myself by loving him." There was a bitter tone to Lucifer's voice as he tossed back the rest of his drink.

Nate wiped his eyes automatically, unaware of the tears. "I think Trent's afraid of that, too," he said tentatively. "Afraid Sebastian thinks Xander is more interesting, afraid Rebecca will find someone she likes better and forget about him again. He got so mad at me after George and I got engaged, even though it was kind of his idea in the first place." At Lucifer's furrowed brow, Nate explained, "After Sebastian abducted Trent for a month and a half, Trent came back traumatized and told me I should marry George because Trent felt ruined."

Lucifer's confusion increased. "Sebastian did what?" he asked.

"Well, he blackmailed Trent into becoming his sex slave. Trent claims he went willingly, but afterwards-- after Rebecca, George, and I found him and got him to come back with us-- he acted like he had been conditioned into averting arguments with sex, and while he did sleep with Rebecca when she asked, he also had a meltdown in the shower afterwards." Nate pressed his lips together. "Trent refused to press charges, then started seeing Serena behind Rebecca's back, though he denied that's what he was doing."

Lucifer looked troubled. "I did wonder why he was willing to pay so much for Serena at auction."

"And he wonders why you never cashed the check." Nate shook his head. "They both frame it as, oh, Sebastian and Trent went on vacation together, and Sebastian got carried away because he loves Trent so much. That's how Trent ended up processing and forgiving Sebastian, and Sebastian sees Rebecca as 'stealing' Trent from him yet again. He probably went to you on the rebound, too."

A shadow crossed over Lucifer's face. "On some level, I always knew he was using me to get over Trent, and yet I allowed myself to hope...." He sighed. "Perhaps Maze is right, and I should kick him out. Break up with him before he breaks up with me. But I can't bring myself to do it. My word is my bond, and I promised to be there for him as long as he needs me. Only he can decide when he no longer does. I try not to think about it," he admitted.

--

Sebastian decided to stretch, get dressed, and head downstairs. He looked through his closet and shook his head, scoffing slightly as he pulled out a sparkling grey dress.

"Might as well...."

--

Twenty minutes later, Serena stalked out of the elevator in grey suede ankle boots that matched her layered-scoop-neck minidress, blinking silver-shadowed eyes in confusion as she saw Nathaniel moving to kiss Lucifer. She cleared her throat as she approached them. She had half a mind to slap Nathaniel, but-- in case earlier hadn't been a dream-- he would like it too much.

Nate smirked to himself as he drew back. "I was wondering when you were going to come down."

"So you thought you'd make out with my boyfriend while you wait." Icicles dripped from Serena's voice, but Nate didn't seem to mind.

"We were having a conversation. About you, actually."

Serena blinked as she sat between them. "Me?"

"The similarities between you and his last girlfriend." Nate was baiting her.

Serena lifted her chin. "Believe it or not, I do know he has a type. So does Trent. It's not a big deal."

Nate laughed in disbelief. "Trent has a type?" he echoed.

Serena pointedly looked over his thin frame and blond hair. "Twinks," she said, a little dismissively. "You just barely qualify, being so tall, but you do have a pretty face, and your voice is lighter than mine."

Nate ignored that. "Lucifer thinks you don't need him anymore now that you and Trent are together and you have Xander," he said bluntly.

Serena scoffed. "Are you our couple's counselor now?"

"Why? Do you think you need one?"

Serena was on top of Nate in a heartbeat, straddling him with her hand squeezing his throat and a dangerous look in her eyes. "Butt out," she snarled. "It is none of your business what goes on between us. And for the record, I don't need you cozying up to him. It's bad enough that Trent is sleeping with you and Luci's sleeping with Rebecca. I don't need you and him hooking up, too."

"If you want a threesome, all you have to do is ask," Nate gasped out. Serena formed a fist, but before she could threaten Nate with it, Lucifer piped up.

"Serena, are you afraid I'm going to like Rebecca or Nathaniel too much?" he asked gently.

Serena's expression wavered and she swallowed. She didn't want to admit it, but she had promised never to lie to Lucifer. "Yes," she whispered.

Lucifer scooped her up and sat her in his lap, cradling her gently. "I'll never leave you unless you ask me to. You know that."

"That's what you promised," Serena said, "but you can still get bored without leaving."

Lucifer looked puzzled. "Why would you think I'd get bored with you?"

"Why wouldn't you? People get bored all the time, once the novelty wears off."

"Are you bored with me?"

"What? No, of course not. I just... you know...." Serena swallowed again. "If I'm around too much and constantly clinging to you, you're not going to want me anymore. You'll resent how much I need you and you'll regret promising to stay.... So it's a good thing Trent and Xander accepted me. Now none of you will have to worry about being bored."

Nate sat closer to them and took Serena's hand. Serena tsked and started to pull back, but thought better of it and let Nate hold her hand.

"Trent isn't going to get bored with you," Nate said seriously. "He said he would have gotten together with you in middle school if he'd known you liked him."

"Nathaniel...." Serena laughed bitterly. "We showered together, slept in the same bed, made out constantly, all since middle school. And in high school and college, I gave him more hand jobs than I can count. He's not a complete idiot. He must have had at least an inkling of how I felt."

Nate licked his lips nervously. "I think he just thought you were being friendly," he said gently. "He didn't seem to think he was cheating on Rebecca when he showered and snuggled in bed with me."

Serena gave Nate a hard look. "He told me the reason I shouldn't grope George is because George belongs to you," she said flatly. "He knew. He just didn't think his family would let him be with a boy, so he went after the first girl who interested him. Funny how none did until he was eighteen. Fuck. We should have gone to Drake."

"Well, you do call him your duckie."

Serena smiled despite herself. "I do," she acknowledged. "It's also weird that he doesn't look twice at any other girl. He practically even told me he prefers me as a man."

"And yet." Nate gestured to Serena's getup.

She shrugged. "Got his attention, though, didn't it?"

"And not just his," said Lucifer. "You make a very fetching woman, though of course, I love you either way."

Serena looked up at him, vulnerable, adoring. "I love you, too," she whispered. "You chose me. You promised to stay with me forever, which-- you know you're stuck with me until the end of time now, right?"

Nate rolled his eyes. "You and Trent are so much alike."

Lucifer stroked Serena's hair. "Or at least until you die," he said.

Serena looked confused and sat up, scooting out of Lucifer's lap. "You're going to abandon me in Hell? Why-- I thought--?"

Lucifer was equally confused. "Hell?"

"Yeah-- I know you're on vacation now, but...." Her lips moved, but she seemed to have trouble formulating words.

Nate looked between the two of them for a moment, then laughed aloud. "No. No way."

"Yes, exactly," said Lucifer. "It's not right. Serena couldn't go--"

"Serena couldn't go to Heaven," Nate said, at almost the same time.

"Thanks," said Serena dryly, "although I agree."

Lucifer frowned. "Well, of course she will. Hell is for the guilty. If she dies, I'll never see her again."

Serena touched her lower back self-consciously. "Is that why you gave me your feather?" she asked. "Because I thought you just wanted me to be more independent. That's why I've been keeping more of a distance since then."

Nate laughed again. "Yeah, no, it makes sense. You're a lot of things, but I doubt you have a guilty bone in your body."

Lucifer stared at his girlfriend. "I gave you my feather because I love you, I know how reckless you are, I don't want you to get sick or injured, and, yes, to prolong your life. It gets a bit tiresome, resurrecting one from the brink of death," he scolded lightly. "Actually, I'm surprised you found me. I thought we'd never meet again after you moved here."

Serena's eyes flew open. "That was you!" she exclaimed.

Nate frowned. "What's going on?"

"After Trent followed Rebecca to New Haven, I started using. I went on some pretty awful benders. A few people told me I was lucky to be alive, but there was one time specifically when I thought I would be dead for sure, but I woke up the next day and didn't even have a hangover. In fact..." She scratched the back of her head. "I rarely ever had hangovers."

"Back then, she did feel guilty, constantly, about helping Trent stalk Rebecca, about not being able to cope with Trent's absence, about not having the guts to have herself transferred to Yale. Mostly, about the drugs and what Trent would think. I saw her soul, her bright, dazzling soul, about to cross over into Hell, where it would surely dim after being subjected to torture. So I brought her back. I stayed with her that night and kept a close eye on her afterwards-- letting her get high, but protecting her life and her body."

Nate was confused. "Her body?"

"For Trent."

Nate blinked a few times, then scoffed. "The Devil, protecting someone's virginity? No, you know what, that actually explains a lot."

Serena looked at Nate impassively. "I got to lose mine to someone I love. Can you say the same?"

Nate looked away. "I lost mine at thirteen, to a pushy classmate who took advantage of my crush on them, so... I don't know. What do you think?"

"I think... better you than me." She shrugged. "Anyway, I thought Lucifer looked familiar when we met here. I didn't realize he was the same guy I'd woken up with in law school. Eh-- fully clothed, I'll have you know."

Lucifer smiled and pulled her back into his lap. "So you see, I'm rather invested in keeping you alive. If it was a simple matter of letting you die and reuniting with you in Hell, if I could even believe that's where you were headed, I'd have let Xander kill you. But I want you alive and I want you enjoying this life, with me, and with whomever else makes you happy."

A placid smile graced Serena's face as she closed her eyes. "Mmm... thank you. You do make me very happy. You, and Trent, and Xander...."

"And Nathaniel?"

Nate made a face. "I told her, that was a one-time thing. I'm not looking forward to explaining it to Trent and George later, especially since George is still so uncomfortable with her."
