Daemons: Aurea (Jace's Golden Retriever), Celestina (Jace's barn owl), Shyama (Magnus' panther), Minerva (Alec's snow owl), Dolios (Max's raccoon), Nagendra (Izzy's cobra), Timon (Lydia's lynx), Seraphina (Clary's robin), Adina (Simon's rat), Ares (Andrew's dog), Piedad (Raph's bat), Menelaus (Cat's lion), Regulus (Madzie's bunny), Lupercalia (Luke's wolf), Cornelius (Imogen's horned owl)

Summary: Everyone had a daemon, an animal-shaped manifestation of their own soul, and bore a picture of their soulmate's daemon on their body. Everyone, aside from Jace. Because Valentine split his soul, giving him two daemons – and took the one on his soulmate's marks. So even when he meets them and recognizes them by their daemons, his daemon doesn't match.

Demon On Your Shoulder

The Split Soul's Soulmates

Chapter 11: The Herondale Heir (1)

"Can we see them?" Magnus was the one to ask, in the end. "Your soul-marks?"

Jace just stared at him for a moment, startled. It hadn't entirely occurred to him just yet that this would be something they'd want. It was late evening, they were getting ready for bed. Tomorrow was the day that Alec and Jace would go back to the institute and Jace was buzzing with nerves – and just perhaps, Magnus wanted to distract him from it. A grin spread over Jace's lips that turned more and more lascivious as Jace slipped his fingers into his pants.

"Mister Bane," Jace winked. "Do you want to get me naked?"

Alec made a sputtering noise, staring from his alpha to his omega (his alpha and his omega! How much he loved the sound of that). And then Jace's fingers started to push down his sweat pants until they pooled down at his ankles so he could step out of them. It wasn't the first time Alec had seen Jace in his underwear – tight briefs, leaving so little to Alec's very wild imagination – but Alec wasn't entirely sure why they were treated to the view right now. At least until Jace grabbed his stele and undid a glamour. Two images became visible on Jace's thighs. Oh.

"There they are," Alec's voice was an awe-filled whisper.

Jace stood, his usual confidence replaced with a tad of awkwardness. He liked being on display, when it was about his prowess or in a sexual situation. This, however, was about laying his soul bare. Showing the marks he had consciously hidden for so many years now. He caught his lower lip between his teeth, biting hard. Magnus got up and walked over to press his finger against that lip, gentling it out of the teeth's harsh grip. And then he leaned in to kiss Jace ever so softly.

"Thank you," Magnus whispered against Jace's lips. "For showing us."

"Of course," Jace leaned in, to get a deeper kiss from his alpha. "I... should have showed you sooner. I didn't... I'm so used to hiding them. Guess that's another thing I have to get used to."

As he spoke, his fingers started playing with the buttons on Magnus' shirt, unbuttoning them ever so slowly. One of Magnus' eyebrows arched curiously, but he made no attempts to stop Jace.

"I just think it's unfair that I'm standing here in nothing but my underwear and you're fully dressed," Jace smirked up at the alpha. "Don't you think that's unfair?"

"I mean you could just get dressed again now," Magnus chuckled. "That's a thing you could do."

"I could," Jace nodded slowly. "I could do that. "Or you could... lose some clothes."

"I could," Magnus nodded his agreement. "I could do that, you're right."

With that, he shrugged out of his by now unbuttoned shirt. Alec next to them made another small noise. Like Magnus alone hadn't been bad enough for Alec – a miserable tease, driving the beta who had denied himself oh-so much oh-so often up the wall with sexual desire – but his parabatai, his very, very sexual parabatai? Now, he had both of them? How was Alec supposed to survive this?

"What about you, parabatai?" Jace turned to look at him with his head tilted and a grin.

With another noise, Alec sat down. Partially, to hide that he was already half-hard, just looking at his half-naked soulmates. Heaving a sigh, he ran his fingers through his hair and looked at them. The teasing look on Jace's face sobered up just a little.

"Hey," Jace cleared his throat. "I don't want to push you into anything you're not comfortable, you know, Alec? Just... something I'm putting out there as something I want... okay?"

"I'm not..." Alec rubbed his face. "I'm not uncomfortable with it, I've wanted you for so long, I'm just considering how much you two are going to...end me."

"Oh, in the best of ways, darling," Magnus smiled, his eyes flashing golden.

Alec made another small noise, this one more miserable than the last one. Still, when Jace grabbed the hem of his shirt, he lifted his arms and let his parabatai pull his shirt off. The way Jace licked his lips, how his eyes darkened as he looked at Alec... This kind of attention, he'd always wanted that.

"How... much... are you comfortable with, parabatai?" Jace asked, tracing his hands along over Alec's chest, the pressure gentle but definitely there, his eyes intense.

"I want everything you're willing to give me, parabatai," Alec rested his own hands on Jace's chest, nearly shy, like he wasn't sure he was allowed. "I've wanted you for so long."

Slowly, Jace approached Alec and came to sit down on the beta's lap, with his knees on either side of Alec's thighs. A grunt from Alec, swallowing hard at the feeling of his omega on his lap like that. Once comfortably seated, Jace craned his neck to look over at Magnus.

"What about you, alpha?"

A dark noise from Magnus, feeling particularly primal being called 'alpha' by Jace when Jace was half-naked on their bed (and on their beta's lap). Rounding the two of them, Magnus went to sit at the head of the bed, comfortably leaning against the head of the bed.

"Whatever you'd like," Magnus offered. "I'm a little older than the two of you, I think I have more patience and I know how long my Alexander has wanted this. Perhaps it'll be... easier to coordinate for now if it's just the two of you, mh? And I... watch, if you don't mind? We'll have more than enough time to find out how the three of us can fit together."

"Probably a good idea," Jace hummed. "Threesomes are fun and all, but... I've never had them with someone where it's more than just a night of passion... and where it's... where we bring more into it than just passion to begin with. Yeah. Okay. So. Alec...?"

Alec grunted, blinking repeatedly as he was torn out of his fantasies. His mind had wandered off, as he was on eye-level with Jace's bare collarbone and just kept staring at his chest. An amused smile stretched over Jace's lips as he noticed the attention he had.

"What do you want to do with me, Alec?"

"Everything," Alec said it in a breath. "Everything."

"Well, I don't think we have that much time," Magnus chuckled amused. "You two do plan on going back to work tomorrow, you remember, darling?"

"Yeah, let's... start with one thing," Jace smirked. "And then work off the rest one by one. Like Mags said, we got time, right? We can do everything."

"Right," Alec grunted his agreement, nodding slowly. "Okay. Let's... start slow. Undressing. Fully."

This time, Jace made a noise of agreement, before he got up so he could get fully naked. Alec fidgeted with his own clothes, too distracted by seeing his omega fully naked and being able to smell the scent of arousal from Jace. Jace was aroused. The concept still startled Alec, he'd wanted this for so long, to have Jace want him, so to be here, to have Jace naked in front of him, to smell Jace's arousal like that... it was overwhelming, in the best way possible.

"Lay down," Alec instructed – nearly ordered. "I want to... I really want to explore your body."

"Sounds good to me," Jace grinned to himself, gladly spreading out on the bed.

He got comfortable in a way that allowed him to rest his head on Magnus' lap. The alpha smiled down at him pleased and the next moment, elegant fingers entangled in Jace's hair. Gently running through it in such a soothing and comforting manner that Jace couldn't help but think I could get used to this. The next moment, Jace sat down between Jace's legs, nudging them apart just enough to give him space. He rested his hands on either side of Jace's torso, looming over him. And Jace though I could definitely get used to this. One of Alec's hands started wandering over Jace's chest, gentle fingers tracing Jace's abs ever so teasingly.

"I want to kiss you," Alec whispered against Jace's lips. "Can I kiss you?"

Mh. Interesting. Jace was used to hot, heavy and quick sex. But there was something very different and very sensual to Alec taking it slow and even asking like that. Jace licked his lips, arching his back some to get more comfortable in Magnus' lap. Oh, this was really good.

"Yes," Jace arched into Alec some. "Please."

So Alec did it. He gave it a soft kiss that gradually deepened, grew more passionate. The soft fingers also grew more daring, slipping down toward Jace's thighs, grasping them, digging in and spreading them. Both were panting breathlessly as they parted from their kiss. Alec sat up some, adjusting his stance a little to support himself so he had both his hands free to explore Jace's body, touching every square inch of soft skin, tracing every rough rune, until his hands were on the soul-marks, touching them possessively. Jace's own fingers entangled in Alec's hair, holding on.

"Can I...?" Alec's hands slipped down further and further.

"Yes," it was a hissed and enthusiastic sound as it left Jace's mouth.

To emphasize, he spread his legs more in invitation. Alec swallowed hard as he slipped his fingers down behind Jace's balls, his other hand teasingly running up the length of Jace's dick, watching it jerk at the touch. Alec licked his lips hungrily. And. Wait. Tilting his head, he leaned down.

"And can I also...?" Alec licked his lips. "Suck you off?"

Jace stared at him surprised for a moment. "Oh fuck yeah."

Magnus chuckled at Jace's reaction. "My, we're spoiling our omega tonight, mh?"

"We waited long enough for him, why shouldn't we?" Alec countered with a grin.

And when he went down on Jace. Pink lips falling open, tongue darting out before he wrapped his lips around the head of Jace's cock. All too soon, Jace turned to jelly under Alec's enthusiastic administration, the warmth of his mouth and cunning tongue, while Magnus was massaging his scalp in a very calming manner. Everything about this made him feel so comfortable and relaxed. Alec moaned around his mouthful of cock, which only sent shocks of pleasure through Jace, who moaned and gasped as he bucked up into Alec's mouth. He tugged on Alec's hair a little more harshly, however Alec seemed to be into it because he moaned at it even louder.

"My, aren't you two gorgeous," Magnus' voice was a dark purring sound.

Jace whimpered when Alec actually breached him, pushing two fingers in quite easily, because Jace was wet and willing and wanted him so much. Perks of being an omega. This was the first time Jace actually got to experience them though, he'd bottomed before, but never while experiencing his body as an omega. He moaned in a drawn-out way when Alec added another finger, scissoring him deep. His slick was coating Alec's fingers as Alec worked him open. It felt intense, more intense than Jace was used to. Made more intense by the fact that Alec was also sucking him off at the same time. It didn't take long for Jace to come, howling out Alec's name as he did.

Alec pulled off, a little cum pearling on his red-swollen lips that were pulled into a pleased smile. His fingers were still working on Jace, until the blonde was calmed down a little. Alec pulled his fingers out only then. Jace reached out for Alec's neck to pull him down into a kiss.

"That everything you wanted to do with me, or...?" Jace's eyes trailed down to Alec's own dick. "Because I have multiple offers on taking care of that. Multiple."

"What would you like most?" Alec asked in return. "If you say multiple offers...?"

"I don't know, I mean, I'd like to return the favor and suck you off too, but after having your fingers inside of me I would also really like your dick in me, not going to lie," Jace shrugged with a grin. "It's tough to decide, honestly? So. Dealer's choice?"

Alec looked genuinely overwhelmed by the choice, his eyes wandering between Jace's lips and between his legs. He took a deep breath, his hands flexing before grasping Jace's thighs on impulse. He was going to take what he'd wanted for so long. Magnus stopped him, offering a condom.

"Let's maybe... take some precautions. Our lovely omega here isn't on birth-control."

Alec's eyes widened with a terrified look on his face. "Didn't think. Forgot. You and me—"

"Yes," Magnus leaned in to kiss his cheek. "I figured that you weren't thinking, love."

Flustered, Alec put the condom on before gently easing himself into Jace. His eyelids fluttered shut as he felt their omega so tight around himself. It felt like they were melting into one person, not just because they were physically one, but also because of the bond. Yes, it had been intense having sex for the first time with Magnus, but there was an additional layer with Jace – the parabatai-bond. There were two soul-bonds connecting Jace and Alec, wrapping around them, entangling them. It was so strong and warm and deep, Alec completely gave himself to it. It felt like he disappeared, like they truly became one. He could feel his own pleasure as much as Jace's pleasure, and when they came, he couldn't tell who came first, or if they came at the same time, he just could tell that it was the most intense orgasm he'd ever felt. Alec collapsed down next to Jace, panting hard and resting his head on Magnus' other, free thigh. The alpha started running his free hand through Alec's hair now, pleased to have both his soulmates happy and in his lap like that.

"And you're happy just having watched?" Jace tilted his head to look up at him.

"Oh, absolutely, that was a beautiful show," Magnus smiled down at him reassuringly. "And we'll have a lot of chances to have fun with each other, in many constellations, mh?"

Jace grunted, accepting the answer as he rolled over to curl against Alec. Out like a candle within moments, just so content, having his alpha and beta with him, having had a really good orgasm for the first time in a while – the war had been too stressful even for finding one-night-stands. Everything was finally working out for the best for Jace, he was finally... happy. Safe.

/break\

Both Alec and Jace looked so good in their tight, black clothes and with these thigh-holsters. Magnus didn't want to let them go, he wanted to unwrap them again right away. Alas, it was time for them to face the music. Especially for Jace. Jace, who looked... troubled. With a frown on his face did Jace kneel down in front of Aurea, grabbing her face gently.

"I... know we've been apart for very, very long," Jace's voice wavered. "But... I don't want to take you to the institute today. Do you mind staying home with Magnus today?"

Jace turned to look up at Magnus to check in with his alpha. Magnus' eyes widened in surprise. To let Magnus and Alec touch his daemons was one thing, but the thought of leaving one of his daemons behind, alone with Magnus? Of course did Magnus nod enthusiastically.

"What do you say, my golden puppy?" Magnus smiled at Aurea, trying to encourage her. "We'll make it a wonderful lazy day at home until our Shadowhunters and owls return, mh?"

Aurea looked distressed at the thought of Jace not being here, but her Magnus was smiling at her and Shayama immediately approached her to lick her face in a soothing manner. Alec frowned.

"Look," Jace sighed. "She may be my grandmother, but... the last time I thought I had family was Jocelyn Fray and she immediately tried to murder me, when she thought I was her son, just because she thought I had demon blood. So... Imogen Herondale is first and foremost the Inquisitor. Nobody ever had two daemons before. I don't... I only just got Aurea back, I'm not willing to risk her yet."

"Right," Alec nodded and swallowed hard. "It is probably... safer here for her, for now?"

"And considering how long the two of you... survived... separated..." Magnus licked his lips slowly before he turned to smile at Aurea again. "Your bond is strong again, sweetie, I'm sure you'll be fine, okay? And if you feel any discomfort, I can open a portal and I will pull our Jace back home."

Aurea nodded reluctantly at that. "Okay... That... That sounds good."

Magnus cupped her face gently. "I promise. We will never let anyone separate you and Jace again."

Only when Aurea relaxed again did Alec and Jace straighten up and get ready to leave.

/break\

"Are you ready for this?" Alec asked, his voice a soft whisper.

"No," Jace reached out for Alec's hand, giving it a tight squeeze. "But I doubt I'll ever be. Just... stay with me, parabatai. I've gone through enough family changes lately. I need you with me."

Alec smiled at that, before knocking at the door – his parents' former office door. The inquisitor called them inside. She sat in the chair like a queen, collected and calm, until she looked up. Until she realized who it was. A flicker on her face. Curiosity. They had sent Isabelle and Clary ahead with the books, allowing them to share them with the inquisitor. Mostly so Jace wouldn't have to carry the whole burden of explaining everything. Imogen knew Jace was her grandson; she also had the DNA test that they had let Izzy run. Alec had never seen this much vulnerability on this woman.

"You're..." Imogen got up and rounded her table, walking up to Jace, her sentence trailing off. "You have... You have your mother's eyes..."

She simply stared into Jace's face, into his eyes. Eyes that widened at that. Eyes that watered at that, without him wanting them to. He'd never really wondered about that. Valentine, as Michael, had never shared pictures of the fake Mrs. Wayland, never talked about her, so his mother had never been a topic. And his identity had changed so, so much, he had no chance to wonder about the Herondales. Stephen and Céline Herondale. What... he may have from them, what features or maybe even behaviors and characteristics? Jace blinked rapidly, trying to stop the tears.

"I... I'm Jace," Jace offered, not knowing what else to say.

"I'm... Imogen," Imogen offered a pained smile. "I... thought I lost you. Your... When your... When your mother died, it was... horrible. We assumed you had died with her... I thought... I thought I lost all my family, I thought... I had nobody left..."

The next moment, Jace had arms wrapped around himself and he found himself pulled into the tightest, fiercest hug. A hug that felt real. Like someone who had spent their life lonely, desperate and like they thought they had nobody left either. Just like Jace. He wrapped shaking arms around her too, though his eyes found Alec over Imogen's shoulder. Alec smiled encouragingly at him.

"I... I thought so too," Jace's voice cracked a little. "That I had nobody. I only had... Valentine... and then he faked his own death. I didn't... I... I would like to get to know you..."

"I'd like that too," Imogen smiled at him when they brought some distance between them again.

She cupped his cheek, looking at his face like she was studying his features. Seeing every facette of Stephen, of Céline and everything that was uniquely Jace, and how it all played together in Jace's face. So many emotions played across Imogen's face – pain, grief, loss, joy, hope, fear too.

"I'm Alec. Alexander Lightwood," Alec spoke up when the silence stretched on too long. "I'm Jace's... parabatai, and his... soulmate."

Oh. Oh, that was the very first time they had said that aloud to anyone else. Jace couldn't help but smile at the way that sounded. He had two soulmates now and they were his, and he was theirs.

"That is not something you hear often," Imogen furrowed her eyebrows, her eyes wandering between Jace and Alec. "I assume this is related to the... books that your sister has brought in? The experiments that Valentine has performed on you?"

She furrowed her brows even deeper as she caressed Jace's cheek. Jace swallowed hard and nodded in a jerky motion. He turned, trying not to look at her, instead, his eyes followed Minerva and Celestina. The two owl-daemons were curiously circling Imogen's own daemon. A huge owl himself, a horned owl. He tilted his head, looking at the two much smaller owls.

"Ah," Imogen cleared her throat. "That is my daemon, Cornelius."

"Celestina, and Alec's daemons Minerva."

"There is... There is so much I want to know about you," Imogen looked at Jace with so much regret. "I want to know everything about you, Jace. How you met your parabatai, how you... are..."

"Jace," Alec cleared his throat, pulling his parabatai close enough to whisper into his ear.

"You sure?" Jace looked surprised but pleased before turning toward Imogen. "Would, ah, would you maybe like to come over for dinner at our place? We could talk in peace."

"Your place," Imogen raised her eyebrows. "You don't live at the institute? But yes, I'd love that."

"We live with our alpha," Jace nodded, heart fluttering at saying 'our alpha'.

So that was his grandmother. He'd met his grandmother. And she seemed... nice. Okay. Good.


Author's note: Sooo, the whole Jace-Imogen conversation was supposed to be in this chapter but then Alec and Jace decided to have sex with each other first and I figured okay why not have a slow first meeting and a deeper second meeting, that makes more sense than dumping everything on Jace and Imogen in the first meeting anyway. So next chapter, dinner at Magnus'! ;)
