Another day, another smutty fic!

Chapter Text

Lan Wangji shouldn’t be out at this moment. It was way past his bedtime. However, he had only come here to get some relief, to forget the omega who had been in his mind for perhaps a month or so.  

However, to his utter dismay [or delight], the omega was here too, taking a late-night dip in the Cold Springs. 

It is forbidden for an alpha to look at any omega other than their own.

The alpha couldn’t take his eyes off the omega, who was not even a foot away from him. 

The omega hadn’t felt his presence yet, and maybe that was good. 

He could only see upto the omega’s bare shoulder that was peaking through the lush black open hair. His robes were discarded on the bank, a few steps away from where Lan Wangji was standing and watching

Lan Wangji hesitated, half-determined to go back to Jingshi, where his omega was presently sleeping. He should go back and maybe vent out his desire on his mate, who wouldn’t even question it. 

But his feet wouldn’t move. He could feel desire stir low and hot in his belly, which was not supposed to happen. He was never unsatisfied with his omega, and yet…

He was so lost in thought that he didn’t hear the sound of water sluicing and sloshing, not until his gaze met the omega’s, who had now turned around, probably to leave. 

“H-hanguang-Jun,” the omega stuttered, his eyes wide with fear and surprise. 

Instead of acknowledging, Lan Wangji could only stare at the expanse of the omega’s bare torso. 

The omega’s nipples were taut from the cold, his waist narrow and hips wide–the perfect body to bear children. The thought made Lan Wangji growl low in his throat. 

Despite his discipline….despite the saying that claimed that Lans only loved once and had a single mate for life…he wanted this omega for himself. 

“Being out this late at night is forbidden,” he managed to sound stern, ignoring the way his cock began to fill out as he stared at the omega, shamelessly standing. 

“Forgive this lowly omega, but shouldn’t Hanguang-Jun also be in his house, instead of being here and conversing with an unmated omega?” The boy’s head tilted to the side, feigning innocence. 

The omega knew he looked alluring, and maybe that’s why he didn’t even try to put on his robes, not even for the decorum’s sake. 

Lan Wangji saw the way the omega’s hips swayed subtly as he stepped onto the bank. He came to stand right in front of him. 

The omega must have picked up on the alpha’s arousal because the alpha could smell the same. The alluring smell of the omega made his senses weaker than they already were. 

Coveting another omega is a shameful act.

“Go back right now,” the alpha commanded, because if the omega didn’t leave, Lan Wangji didn’t know what would happen. 

“Do you really want that, Alpha? Do you really want me to leave?” The omega came closer, his gaze imploring. 

Lan Wangji’s jaw clenched as he tried looking anywhere but at the omega, at the temptation that begged him to take. 

When the omega received no answer, he dared to place a delicate hand lightly over the alpha’s chest—a daring act for an unmated omega who knew the alpha was mated. 

“I have seen how you look at me, Hanguang-Jun, see your eyes linger on me longer than it should be decent,” the omega whispered. 

Lan Wangji inhaled sharply but didn’t move the omega’s hand away. 

The omega’s hand wandered southward, making the alpha swallow. What spell had this minx cast on him? Why couldn’t he leave? Except for his mate, he hated others touching him, and yet this omega’s touch didn’t make him recoil but made him want more. 

“I can smell your desire, Alpha. And I’m sure you can smell mine….and I want th–”

The omega hadn’t even finished the sentence when Lan Wangji, unable to take it anymore, had grabbed the hand on his chest, twisted it behind the omega’s back, and pinned him to the nearest boulder. 

His restraint had snapped, and here, in the silence of the Cold Springs, no one apart from them existed. 

“So rough, Hanguang-Jun! Be gentle with this poor virgin omega,” the boy whined, although he moved his hips back, gasping when his plush bottom brushed against the alpha’s impressive length. 

“Shut up. Always talking. Always frivolous,” Lan Wangji growled as he let go of the boy’s hand in favour of snaking his arm around the other’s waist so his back was flush against his chest. 

“You never stopped me,” The omega replied breathily. 

The alpha bit his shoulder in retaliation, making the boy yelp. Lan Wangji had never felt so unrestrained, not even when he met his mate. This omega brought out his bestial side, the darker facet that he tries to keep hidden even from his mate. 

“That hurt! You can’t bite me like this. How will I explain the bruises to my friends?” The omega protested, but his actions contradicted his words as he tilted his head to bare his neck. 

Lan Wangji’s cock twitched at the thought of this omega bearing his marks, even if they would be temporary. 

Lans only mate once in their lifetime. 

The alpha’s other hand pushed down the omega’s wet trousers. His breath hitched when he saw the omega wasn’t wearing any undergarments. 

“Shameless omega. Were you hoping for someone to find you like this?” he demanded as he pushed two fingers into the omega’s slick folds. 

The omega moaned, rocking his hips. “N-no….I…I didn’t know any-anyone would be here.” 

“Do not lie,” Lan Wangji retorted as his thumbs found the clit. 

The omega whimpered. “I…I…”

“You wanted someone to take your virginity today.” Lan Wangji added another finger, suddenly envious of the person whom this omega wanted to take his virginity.

“You…you…I wanted it to be you.” The omega moaned, thrusting his hips as more slick dribbled out of him, trickling down his inner thighs. 

A selfish part of Lan Wangji screamed that it was wrong, while the irrational part was overjoyed at the omega’s words. 

“You must not lie,” the alpha warned even as he let go of the omega’s waist in favor of undoing his trousers’ drawstrings. 

“No…I am telling…ah…the truth…” The omega rotated his hips, his eyes now closed and head thrown back, resting on the alpha’s clothed chest. 

Lan Wangji growled low in his throat and pulled his fingers out, making the omega whine. But before the omega could say anything, he had pushed his cock into the omega’s tight heat. 

The omega screamed as the alpha relentlessly pushed until he was buried inside the omega completely. Clasping the narrow waist, the alpha set a punishing pace.

They were here in the open where anyone could walk in and see them like this, locked in intimacy. Instead of shame and fear, Lan Wangji felt possessiveness curl in his chest. Whoever walked in on them would know who this omega belonged to now. 

The omega moaned and sobbed as Lan Wangji’s hand crept up to twist his left nipple while the other snaked forward to toy with his sensitive clit. 

“Yes…yes…please…right there…” the omega continued brokenly, chanting in between groans, incapable of any other words. 

Lan Wangji felt delirious, kissing and sinking his teeth on any available unmarked path of skin. His irrational part wanted this to never end, so that he could keep this omega hidden and for himself. 

This night only increased his hunger for the omega. He realized, as he pounded into the omega, that maybe they would repeat this later, and continue as long as no one found out. 

The thought made Lan Wangji push in harder, grind his hips more, and be meaner to the omega. 

The omega came with a broken sob, and soon the alpha could feel his knot forming. 

“Don’t pull out. I want your knot. I want evidence of this night, please,” The omega begged, and how could Lan Wangji say no to that? 

He slammed in once before the knot flared. The omega collapsed in his hold. 

“Lan Zhan! When I tell you to do something, don’t just obey! Aiyah, now we’re stuck here for two hours!” Wei Ying whined, promptly breaking the script, and giving his husband and mate a beleaguered side eye. 

Lan Zhan, for his part, didn’t look the least bit remorseful or chastened. 

“I have put up a spell that will keep anyone from coming this way,” he replied as if that was a solution. 

“That’s not the point. Look at me! I am half naked, and you? You’re still wearing clothes! Lan–ahhh…”

Wei Ying was cut off mid-rant as Lan Zhan jostled him a bit, his knot brushing the omega’s sweet spot. 

“My omega looks beautiful like this. How could I resist, ài rén?” Lan Zhan murmured, brushing his lips over the omega’s mating mark. 

“Lan Zhan…don’t say things like this!” Wei Ying mewled as Lan Zhan suckled over the mark. 

Then, with practised ease, he turned his mate around, without pulling out. 

Wei Ying’s arms came around his neck immediately, and the alpha gingerly hitched his legs up around his waist. 

“Kiss me,” his omega demanded, and who was Lan Wangji to say no?

He reeled in the omega in a deep, passionate kiss, moving his hips slowly to feel the inner walls clench around his knot, to feel his omega's tight heat around him. 

Lan Zhan picked up Wei Ying’s discarded robe that was lying on one of the boulders, thankfully at a height that didn’t make him bend. 

He threw it over the omega, covering his modesty, and began to walk. 

“Wait…Lan Zhan…you’re not seriously planning to walk like this, right?” For all the shamelessness that he showed in public, Wei Ying was the one who got most flustered. 

“Mn,” Lan Zhan simply said, clamping a hand around his mate’s waist, not showing any reaction to how the action made his omega produce more slick. 

“But…but…what if someone sees?” Wei Ying asked, sounding partly gleeful as the alpha began to walk. 

“No one will have the audacity to stay awake at this hour,” Lan Zhan replied as he undid the spell that he had cast around the Cold Springs. As much as he had liked the idea of someone seeing them, he didn’t want anyone to see his mate in the throes of passion. This sight was for his eyes alone. 

“But why would you take me home, Alpha? What if your mate wakes up and sees another omega in his home?” Wei Ying suddenly asked, lowering his voice and slipping back into the role of an unmated omega who had attracted the venerable and mated Hanguang-Jun’s attention. 

Lan Zhan’s eyes darkened, and his grip tightened. 

“He won’t.” Lan Zhan’s voice was firm. 

“Why?” Wei Ying asked, brushing his lips against Lan Zhan’s.

“Because he’s in my arms right now,” Lan Zhan replied promptly. 

“Lan Zhan!!!”
