Whenever Jiang Cheng tried to recall his wedding night, he usually only remembered half of the night. The rest of it blurred together in vivid flashes of lewd images and obscene sounds, one orgasm blending into another, too many sweat-slicked limbs tangling and grasping at each other. He couldn’t even tell how many times he came that night.
They were very pleasant memories.
He never, ever not blushed.
Wei Ying, who had a reason to spend more time with him now that Wei Ying and Lan Wangji were courting, could always tell when Jiang Cheng was thinking about that night, and mercilessly teased him for it.
“My shidi is so cute!” He’d wrap an arm around Jiang Cheng’s shoulder, never failing to draw a few disapproving looks from the Lan disciples and elders alike whenever they were within the Lan sect walls.
If they only knew of the arrangement Wei Ying and Jiang Cheng — the Lan-furen — had with his mate, Lan Xichen. And his brother-in-law, Lan Wangji.
(Whom Wei Ying was courting in a very rare display of an omega actively courting an alpha.)
The revered Twin Jades of Gusu Lan.
**
This was what Jiang Cheng remembered:
It wasn’t until he was naked and leaning against the broad, firm chest of his husband, that Jiang Cheng realised that his wedding night was surely out of the norm.
He didn’t expect it to be normal, but he expected to spend it only with the Twin Jades. He’d known this for months, in fact, and had agreed to marry Lan Xichen fully knowing that he would be sharing his mate with his brother-in-law. Fully knowing that he would be shared between the two alphas.
Wei Ying was the unexpected part of it.
He went through his courting thinking that his shixiong, another omega, would only be involved as a chaperone, and later simply a member of his maiden family’s wedding entourage. A past.
Wei Ying and he had been together — though in secret — until he decided to accept Lan Xichen’s proposal. They’d both accepted that it was a relationship that could not go anywhere. There was family honour and sect politics and the life-debt Wei Ying owed to his parents complicating an already-unusual same-sex relationship.
So when Lan Wangji brought Wei Ying back from the festivities to the hanshi, a surprise that apparently had been arranged by both he and Lan Xichen, Jiang Cheng was- well, thankful would be the least of it.
(And still a bit surprised that Lan Wangji would so readily share his brother, his lover of almost a decade, with a strange omega — one that he never showed any particular interest to before.)
“Wanyin,” Xichen’s — his mate’s — hands crept up the insides of his thighs, “Is this your first time with an alpha?” His breath was warm on the back of Jiang Cheng’s ear, pulling a shudder from him.
“Yeah — yes.”
“Oh, precious,” Xichen cooed. “I promise we’ll make it so good for you.” His thumbs were stroking small circles on the back of Jiang Cheng’s knees.
Oh, Jiang Cheng never doubted it. Lan Xichen was the kindest alpha he’d ever met, aside from his older sister, and he’d never not delivered on his promises.
“Now, will you let Wangji taste you?”
Jiang Cheng inhaled sharply as Lan Xichen pulled on his legs, spreading him wide for the hungry gaze of Lan Wangji. Beside him, Wei Ying whispered something to Lan Wangji, and his shixiong’s smile should worry Jiang Cheng, but it just made him flush with anticipation.
Lan Wangji and Wei Ying were in a similar state of undress: Lan Wangji was in soft sleeping pants and Wei Ying completely bare like him and Lan Xichen. Wei Ying had helped Lan Wangji untie his forehead ribbon — something that did not escape his or Xichen’s attention. Jiang Cheng had only dared touch Lan Xichen’s ribbon tonight.
Perhaps a lot more happened between the Second Jade and his shixiong when they weren’t looking.
Jiang Cheng watched with bated breath as Lan Wangji crawled between his legs. He stopped to nose on the damp curls on top of Jiang Cheng’s folds.
“You smell good.” He murmured, his warm breath a nice contrast to the cold air caressing his sex.
“Doesn’t he, Lan Zhan?” Wei Ying, now cuddled up on Jiang Cheng’s other side, reached between Jiang Cheng’s legs to open up his sex with two fingers.
Jiang Cheng fidgeted, biting back a moan. His whole body felt warm, almost like he was in pre-heat, despite knowing it was still months away. He felt so wet, so exposed, with Lan Xichen’s arms holding him open and Wei Ying’s hand literally putting him on display for Lan Wangji.
“Mn.”
“Ah!” His hips rocked up when Lan Wangji took a long lap up his opening. Lan Wangji didn’t give him time to breathe — he buried his tongue between Jiang Cheng’s folds and started licking hard and deep as if he couldn’t get enough of his wet.
“Slowly, A-Zhan,” Xichen’s deep voice rumbled beside him. Not in rebuke, but coaxing. Lan Wangji obeyed immediately, tempering his touch. “Yes, like that.” Xichen reached over and brushed Lan Wangji’s hair away from his forehead, tucking it behind his ear. The motion was so gentle, it almost looked out of place in the situation.
“Lan Zhan practised on me, you know?” Wei Ying murmured, two fingers caressing Jiang Cheng’s nub in familiar motions. “Don’t you think I’ve taught him well? He’s always so eager… Can’t you feel how eager he is, shidi? What a good boy.”
Lan Wangji clearly heard Wei Ying because his hips bucked against the bed. He made a low hum, and Jiang Cheng had to muffle his whine on the back of his hand.
“A-Zhan likes it when you pull his hair,” Xichen said.
What else could Jiang Cheng do but slip his fingers between the alpha’s hair? His fingers curled tight on Lan Wangji’s scalp when the alpha started sucking on his clit, hips jerking, and Lan Wangji moaned.
“Oh, he does.” Wei Ying breathed, “He’s gonna make you come so hard, Chengcheng.”
Truly, between Lan Wangji’s relentless tongue, Lan Xichen’s coaching, and Wei Ying’s dirty, dirty mouth, Jiang Cheng had no chance. It felt like only minutes had passed before his hips seized and he wailed loudly, throwing his head back on his husband’s shoulder, coming in long waves.
Wei Ying’s laughter was loud beside him, and his shixiong pulled him for a feverish, joyful kiss. “That was amazing! You look so pretty coming like that, Chengcheng!”
“Gods,” Jiang Cheng panted, “you… I can’t believe you did that.”
Wei Ying laughed again and nipped on his lower lip. “Gotta make sure my shidi gets the best orgasms.”
Lan Wangji looked debauched when he sat up, lips swollen and chin damp. Lan Xichen reached across the space and grasped the back of Lan Wangji’s neck, pulling him into a hard kiss, licking into his mouth thoroughly. Lan Wangji made a soft noise and surrendered to the kiss, entirely unlike the way he took control when he kissed Jiang Cheng earlier. It was a long while before they parted, panting.
Jiang Cheng’s toes curled when he realised that they were sharing his taste. Arousal surged quickly inside him and his scent must’ve intensified with it because the alphas were now looking at him with interested eyes.
“Xiongzhang should fuck Jiang Wanyin now,” Lan Wangji said, his voice husky.
Jiang Cheng could feel Lan Xichen’s cock, rock-hard behind him, pressing against his lower back.
“Is that okay, Wanyin?” Lan Xichen asked. “Do you want my knot?”
A pool of heat bloomed within Jiang Cheng. The thought scared him, just slightly, he’d never taken a knot before. But he’d had Wei Ying share with him what it felt like to have the weight of a knot inside him, to feel so full almost all thoughts were driven out of his head. He’d always gushed hard on Wei Ying’s fingers when Wei Ying talked to him like that.
He nodded.
Lan Wangji and his brother rearranged themselves in a manner that was almost practiced, and somehow Jiang Cheng’s head was now cradled against Lan Wangji’s firm stomach, Lan Xichen kneeling between his splayed legs. Jiang Cheng finally had a good look at Lan Xichen’s cock and his breath involuntarily hitched at the size of it. He had no idea how that would fit inside him, but he was desperate to try.
Wei Ying laid down beside him, and his presence was its own kind of comfort. As Lan Xichen pushed into him, Jiang Cheng cried out and grabbed Wei Ying’s hand. Lan Xichen was so big, his length felt like silk-covered steel and for a moment Jiang Cheng thought he was going to split into two.
He felt Lan Wangji’s fingers stroking his hairline, trying to soothe him. The other alpha was murmuring a constant stream of comfort, about how his xiongzhang would be so gentle, he was always so gentle, even when he fucked his Wangji for the first time, even then, he was so gentle, so patient, there was barely any pain.
Jiang Cheng held on to those words. He was trembling, burning from his core, so overwhelmed he couldn’t stop mewling. But Lan Wangji was right — there was no pain, not even as Lan Xichen rocked further forward, carving a space inside Jiang Cheng, incinerating him from inside.
“You’ve done it, A-Cheng,” Wei Ying said, clear awe in his voice. “You’ve taken all of Lan da-ge.”
(If Jiang Cheng was in a more lucid headspace, he might have noticed the dark hunger in Wei Ying’s tone.)
Lan Xichen said something that he completely missed in his haze, and then started moving his hips. His thrusts were slow and languid, and Jiang Cheng could feel every part of him sliding smooth — all delicious friction, no pain.
Lan Xichen was a skillful lover, hands roaming across Jiang Cheng’s body, tweaking his nipples and pressing into the divots in his hips. Everywhere he touched left a trail of invisible fire that made Jiang Cheng shiver and only seemed to heighten his pleasure, bringing him higher and higher until he was afraid he might break into pieces.
And then, suddenly, there were fingers on his clit and Jiang Cheng shouted as his orgasm crashed into him without warning, his back arching so high he was resting his weight entirely on his neck. It felt different from coming from Wei Ying’s fingers, like Lan Xichen’s weight inside him was too much and not enough at the same time.
He crashed back down, breathing raggedly, and Lan Xichen had slowed his thrusts to a crawl.
“So beautiful, A-Cheng,” Wei Ying was whispering beside him, wet fingers stroking his stomach. And then: “He has one more in him, Zewu-jun.”
Jiang Cheng’s hips twitched. He caught Lan Xichen’s bright, intense gaze and saw a shift in those eyes.
“Yes, he does.” The alpha murmured. His pace picked up again, now less languorous, less patient, chasing his own pleasure as much as Jiang Cheng’s. Jiang Cheng raised his hips and wailed when the shift made Lan Xichen’s cock hit a spot inside him that electrified his nerves.
Like a wolf chasing his prey, Lan Xichen chased that spot inside him and rammed his hips so hard Jiang Cheng could hear the sounds of their flesh slapping together. His aim was unerringly accurate. Jiang Cheng was losing his mind.
“I’m going to knot you now,” Lan Xichen said, suddenly. His voice had lowered in pitch until it sounded more like a growl. Jiang Cheng felt a shiver arc up his spine and had to subdue the primal urge to surrender demanded by his mate’s voice.
Lan Xichen’s thrusts turned bestial, as if he was trying to reach a place inside Jiang Cheng he didn’t even know was possible. Jiang Cheng could feel it when the knot was finally inside him, just for a split second, because then he dissolved into pure pleasure.
Jiang Cheng shook and shook and shook as his orgasm overwhelmed him, gasping and clawing for breath, and for a moment he didn’t know if it would ever stop.
When he came to, Jiang Cheng realised the high-pitched mewling he heard was coming from himself. Gods, it was like he couldn’t stop making these sounds.
Being knotted was unlike anything he’d ever experienced. He felt full to bursting, virtually no space left between him and Lan Xichen, but his walls were still pulsing, trying to clutch harder into the weight in it.
Lan Xichen was smiling down at him, but he looked the most wrecked Jiang Cheng had ever seen him. He was still attentive and kind, kissing Jiang Cheng’s overwhelmed tears away, murmuring praises into his ears: so beautiful, taking my knot so well, you were made for this, Wanyin.
He dimly wondered if this was what being struck by lightning felt like — pleasure so absolute he could feel it to the tips of his fingers. Even as the sharp edges faded, he still felt the buzz of it under his skin, ten times stronger than receiving a qi transfer.
He turned his blurry gaze up and saw Lan Wangji watching them intently, whose fingers were still resting on Jiang Cheng’s scalp, and saw something in his eyes like —
Like —
Like pain and envy and deep sadness.
Lan Wangji noticed Jiang Cheng looking and flicked his gaze away, and emotions bled from his eyes, turning them back to their usual sheen of indifference.
Jiang Cheng felt like he’d just seen something he wasn’t supposed to. He hastily looked away, just as Lan Xichen had shrunk enough to pull out. The Alpha dislodged himself carefully, and Jiang Cheng quivered when he felt something drip out of his opening.
It felt obscene.
His embarrassment was quickly warring with exhaustion. It felt like his last orgasm has zapped all of his energy. He stifled a yawn, and, to his mild surprise, Lan Wangji simply repositioned him until he was snuggled comfortably in his embrace, a chaste kiss pressed on top of his head.
“Rest,” He heard Lan Wangji’s voice. “I’ll take care of you.” Jiang Cheng would never be able to say why, but he felt comforted and reassured by those words.
Jiang Cheng had drifted into a light doze after, nosing into Lan Wangji’s calming sandalwood scent, limbs lax and weightless. Lan Wangji was running a warm rag across his stomach and between his legs, wiping away dried come and sweat, his touch so pleasant Jiang Cheng felt like he was suspended in that liminal space of sleep and wakefulness.
He blinked blearily when he detected a change in Lan Wangji’s scent, the sharp tang of the alpha’s arousal clouding the back of his throat.
“Xichen-ge,” Wei Ying’s whimper rang clearly from across the room, and Jiang Cheng turned to look. “Da-ge, alpha, please —”
Wei Ying was riding Lan Xichen’s cock, his hands clawing deep into the alpha’s back as he bounced on the hard shaft in abandon. Lan Xichen’s hands seemed obscenely big around Wei Ying’s waist, pulling the omega harshly onto his cock while his hips snapped up in a punishing rhythm.
Lan Xichen was whispering endearments into Wei Ying’s flushed ear, though Wei Ying’s loud cries drowned his words. Jiang Cheng knew how much Wei Ying craved praises, something Jiang Cheng was never a natural at giving — he was not good with words, in general. Jiang Cheng thought he would be jealous that Wei Ying was getting them from someone else, from his husband, even, but all he felt was fondness.
The picture they made was profane. Wei Ying looked small, almost delicate, on Lan Xichen’s lap. Jiang Cheng was reminded of the fact that Wei Ying was a head taller than him and reeled at the notion of how small he looked speared on his mate’s cock.
Jiang Cheng felt the beginning of pleasure curling in his core, a fresh wave of heat rolling through his body. There was an answering twitch from Lan Wangji’s cock, pressing against the small of his back.
He tilted his head up and waited until Lan Wangji looked down at him. He said; “I think you should fuck me.”
Lan Wangji looked at him for long moments before leaning in to catch his lips. This kiss was softer, languid, but it had the same intensity as their first kiss. A moan escaped Jiang Cheng’s lips as he placed a hand on the base of Lan Wangji’s neck, anchoring himself.
“I’ve never —”
“Not with Wei Ying?”
Lan Wangji shook his head. “Only hands and mouths.”
Jiang Cheng nodded, still stroking the alpha’s cheek. “Would you like to knot me, then?”
The minute twitch at the corners of Lan Wangji’s eyes would not be detectable if Jiang Cheng wasn’t already looking at him closely.
“Jiang Wanyin would let me do that?”
Jiang Cheng thought about the split-second of pain he saw in Lan Wangji’s eyes earlier. Though he wasn’t sure how he could alleviate it, wasn’t even sure it was within his power to, he still wanted to comfort Lan Wangji.
He nodded. Then, just to make himself clearer, “Yes, I will.”
“Then Wangji would be honoured.”
Jiang Cheng shifted from Lan Wangji’s embrace and crawled forward, halting after a short distance. Hiding his face in his arms, he arched his back and presented himself, hearing Lan Wangji’s sharp inhale behind him.
Across the room, Wei Ying’s loud cries had tapered off into a continuous keen, overlaid by Lan Xichen’s harsh grunts. Jiang Cheng knew, intimately, how that felt. He wanted to feel it again.
A hand rested on the small of his back. Lan Wangji was clearly telegraphing his movement, but Jiang Cheng still jolted. His stomach was a mess of butterflies.
Lan Wangji’s cock was as big as Lan Xichen’s, and Jiang Cheng savoured the same not-quite-fear of thinking that he’d be split like an overripe peach. It was exquisite. Jiang Cheng could not stifle his moan.
Lan Wangji set a hard, fast pace from the beginning, and Jiang Cheng felt the pleasure tingling to the tips of his toes. He screwed his eyes shut, mewling into his forearm every time Lan Wangji shoved into him, each well-aimed thrust sending shocks of ecstasy into his core.
Like his brother, the Second Jade’s stamina was unqualified, his aim perfect. It would’ve been outrageous if Jiang Cheng didn’t feel so consumed with pleasure. With a finger on Jiang Cheng’s clit, Lan Wangji swiftly brought Jiang Cheng to the brink and didn’t relent even as Jiang Cheng came around him with a shout.
Lan Wangji simply fucked him through it.
Undeterred, Jiang Cheng clenched his thighs and keened, high and sharp, when Lan Wangji responded in kind. The pleasure zapping up his spine was almost painful in its intensity — he couldn’t — gods —
He felt fingers grasping his cheeks and opened his eyes to Wei Ying, shushing him and brushing his tears away.
“A-Cheng,” Wei Ying said, voice soothing, as if he was talking to a child, “Baby, do you want to stop?”
Lan Wangji’s hips stilled immediately.
Jiang Cheng let out a protesting sob. He shook his head resolutely.
“No — I need, keep going.” Jiang Cheng knew what he needed. He pulled Wei Ying closer, pushed him down until he could crawl between Wei Ying’s spread legs. He needed to lose his mind to something else, to temper his overstimulated nerve endings.
Lan Wangji started moving again, hesitant at first, but then, as Jiang Cheng buried his face in Wei Ying’s sex and started mouthing on his clit, the alpha groaned and resumed his punishing pace.
Belatedly, Jiang Cheng realised that he could drink Lan Xichen’s come from within Wei Ying and he dug deeper, addicted to the mingling taste of Wei Ying and his mate — one he was in love with and the other one part of the two alphas he was growing strong feelings for.
Under his mouth, Wei Ying's hips rolled, as if he was trying to get away and move closer to him at the same time. A sure sign that he was close.
“Baobei,” Wei Ying mumbled, “My sweet shidi, what a good boy, ah—”
Jiang Cheng held him down, tongue flicking against the spot he knew always ruined Wei Ying, and his shixiong gushed with a wail, voice cracking as he was forced to reach another peak so soon after being knotted.
Pressing his forehead on the inside of Wei Ying’s thigh, Jiang Cheng breathed in the sharp, comforting scent of his shixiong. Now that he didn’t have Wei Ying to distract him, the pleasure emanating from his lower body was coming back to him in waves.
Jiang Cheng yelped as he was manhandled onto his back, Lan Wangji’s cock barely leaving him before it buried itself back in in a savage thrust.
“Close —” The alpha bit out. “Knot — can I —”
Jiang Cheng looked over Lan Wangji’s shoulder and caught his mate’s eyes.
There was no demand in those eyes. Lan Xichen was letting him make this choice.
“Yes.” Jiang Cheng nodded. “Come in me, Wangji-ge.”
“Go ahead, didi.”
Lan Wangji let out a guttural groan as he burst inside Jiang Cheng in long pulses, his hips snapping erratically until his knot sank snug in Jiang Cheng, punching a cry from the smaller man and a small but vicious orgasm.
When Jiang Cheng returned to himself, he hazily watched Lan Xichen gentling Lan Wangji’s hurt noises, letting the younger alpha gnaw and bite on his scent glands. Jiang Cheng was reminded that this was the first time Lan Wangji had ever knotted an omega and couldn’t help but feel a tender fondness for the second jade.
He reached up with both arms and Lan Wangji instinctively melted into his embrace.
“You fill me up so well,” he mumbled, pressing soft kisses on the alpha’s damp temple, half-high from the feeling of being so full. His words made Lan Wangji whine and nose deeper into the crook of Jiang Cheng’s neck.
Over his shoulder, Lan Xichen was watching them with an affectionate gaze and they exchanged a small smile before the older jade bent down to press a kiss on Wangji’s nape. “Wangji did very well.”
Wangji’s cock twitched inside him, and Jiang Cheng shook with laughter.
He fell asleep — a deep one — after that.
He woke up after what felt like only minutes. He didn’t know what the hour was, but it was still dark; no light was peeking in from the hanshi’s window panes. He was cuddled up snugly to Wei Ying, whom Jiang Cheng could recognise from scent alone.
He flexed his fingers and toes. He was clean, dry, and dressed in the softest, silkiest sleeping robes his skin had ever felt the pleasure to feel. Someone had taken the time to brush and do his hair in a loose braid to avoid tangling.
Jiang Cheng smiled as he nosed into Wei Ying’s chest, simple happiness blooming in his chest.
“Chengcheng?” Wei Ying asked somewhere from above him, voice so soft it was almost inaudible.
Jiang Cheng replied by rubbing his nose into his shixiong’s collar bone.
“There’s a show if you’re interested”
Jiang Cheng’s eyes snapped open. Now that the cloud of sleep was leaving him, he could hear muffled noises from across the room.
He slowly turned around, careful not to make any sound.
In the dim light of the few candles that were left burning, Jiang Cheng could make out the shapes of the Twin Jades on the floor, tangled together in the most intimate of ways.
Lan Wangji’s stoic face had lost all composure, eyes screwed shut and mouth agape in a rictus of silent ecstasy as his brother drove into him again and again. He was a writhing creature of pleasure, reduced into bitten-back moans and trembling thighs. It was mesmerising to witness.
Lan Xichen’s thrusts were coloured with the kind of desperation that wasn’t there when he was fucking Jiang Cheng or Wei Ying, and Jiang Cheng wondered if this was what his husband was like when he truly let himself go.
(When he was at his most honest.)
If Jiang Cheng strained his ears, he could hear the shuffles of their knees on the floor, the muffled slaps of their bodies. Lan Xichen had his nose buried into his brother’s nape, biting and mouthing what Jiang Cheng imagined were love confessions. One of his hands was trapped in one of Lan Wangji’s own, fingers squeezing tight as Lan Wangji held on white-knuckled. His other hand furiously moved under Lan Wangji’s stomach, at an angle that was not privy to Jiang Cheng’s sight.
They watched in silent stillness until Lan Wangji reached his peak, a wrecked voice calling out, “Gege, gege —” so desperately Jiang Cheng felt himself blushing. Lan Xichen followed almost simultaneously, as if he was just waiting for his brother to reach his pleasure first.
After a long, still moment filled with the sound of breathing, Lan Xichen pulled out of his brother and cuddled him close. He pressed reverent kisses all over his Lan Wangji’s face, murmuring things Jiang Cheng could only make out a few words of: always, yours, my fated one.
Jiang Cheng probably shouldn’t be hearing this.
He quietly turned around to face Wei Ying again, who had also averted his eyes from the intimate scene.
“A-Xian,” He tugged on the lapel of Wei Ying’s sleep shirt. “Xian-ge.”
“Mmm?”
“Thank you for being here.” He mumbled. “I’m really happy.”
Jiang Cheng could feel Wei Ying physically restraining himself from making jokes, and it made him grin.
“Well,” Wei Ying said, after a while. “If I have anything to say about it, we’ll be able to see each other more often. And perhaps, in six months, I’ll move here.”
Jiang Cheng’s head snapped up. “You mean…” He had his suspicions, but he didn’t dare hope. Surely the gods couldn’t be so kind to give him everything — everyone — he’d ever wanted. “Did Lan Wangji…”
“Well, no.” Wei Ying said, and then, because he was both shameless and embarrassing, raised his voice just loud enough for Lan Wangji and Lan Xichen to hear: “If Lan er-gege doesn’t do it, I’m going to court him.”
There was a brief, stunned silence, and then Jiang Cheng heard Lan Xichen make an utterly inelegant snort, followed by muffled laughter.
“Mark your words, Wei Ying.” came the reply.
