Omegas had little say when it came to their bodies. 

When they were young, they were under the control of their alpha parent, and as they grew to maturity, they would be handed over to another alpha, who would mate them, breed them, and use them to their liking. It was like a shifting of control. 

Of course, not all sects view the secondary gender the same.

Being an omega was just the same as being another gender in Qinghe Nie, they didn’t face any discrimination in rank or power, all received the same training and treatment. While being in Langling Jin was an omega’s worst nightmare, it meant being nothing but a tool for breeding and pleasure of the leering the alphas. Their rules allowed alphas to mount omegas except those of the mainline, and rumors that it was an unspoken rule that all omegas were to be first presented to the sect leader, and after he had his way with them, he would mate them off to others according to how ‘good’ they were. The GusuLans treated their Omegas as sacred members of the society, that is with the highest respect, yet that respect was too stifling as they were confined to only certain ‘pure’ regions within Gusu. They were trained in everything, cultivation, domestic chores, and pleasure their alpha, and are even given powerful positions within the sect. But their rules of conduct were ten times more than those for others. Yanli often pitied the straight backs and the 10 layers that Lan Xichen was forced to wear every time he came to visit. 

And then there were the Yunmeng Jiangs, a perfect balance of the rest. Here the genders were never considered a barrier. Her father believed that all genders had their own part to play in life based on their unique biological attributes. That made them stronger, not weaker. The sturdy and more agile bodies of the alphas would be trained and used to fight and protect the cunning and smart-brained betas, and the nurturing and healing omegas. Of course, they had beta and omega soldiers, alpha healers, and omega administrators, but they were exceptions. It was up to to the individual at the end of the day.

Yanli was an Omega, the eldest daughter of Yunmeng Jiang. And she cherished the freedom she got, knowing somewhere deep in her heart that it might not last that long. As the eldest daughter of the sect leader, it was her duty to strengthen the sect through marriage alliances. That's why she had accepted it when her mother first suggested an alliance with the Jins, though she had despised the Sect and its perverted leader since she was 10 years old and the man had tried to peak at her while bathing. But she didn’t refuse, she didn’t know that was an option.

She had had her first heat last week. And having reached ‘maturity’, her informal betrothal to the Jins would now become formal, the bridal price and the dowry will start being arranged and within the year, she will be at the mercy of Jin Zixuan and his sex-hungry feind of a father. Her father had been enraged at this arrangement being done without his consent. She was his daughter before she was Madam Yu’s ward, everyone knew. He had taken her aside and given her the right to refuse. But she thought of her mother and kept silent, Her alpha mother and the beta Madam Jin had promised to wed their kids to each other in their youth, a promise to give their children what they couldn’t have for themselves. Besides, she didn’t see any other option for herself. The Nie Alpha had married Lan Xichen a few months back, they were already expecting a child. The only other alpha from the main four sects was Jin Zixuan. She did have another option, but that had slipped away two months ago with a formal betrothal being announced to the world. She understood her father’s rationale - marry your chosen mate - and also her mother's - increasing closeness through marital alliance.

Yanli had grown up to the stories of her parent's troubled marriage. Both were alphas - stubborn to their core. In the 20 years of their marriage, they had slept in the same room only 3 times, on their wedding night, to conceive a brother she held for two days, and then A-Cheng, aka out of necessity to produce an heir. When she was younger, she thought that maybe it had been her fault that her parents didn’t get along, after all, the heir had to be an alpha and she was born an omega. But as she grew older, she understood that they both had fallen in love with others. She saw the smiles that would light up her mother's face when Madam Jin came for a visit, or how her father would always look into the crowds of people or sometimes trees when they traveled as if searching for someone.

But that was their life. She shouldn’t be a vehicle for fulfilling her mother’s desire. She knew what the engagement to the Jins had meant to her mother. She had heard her father shout for the first time, making his refusal clear. But mother had stolen the sect leader’s seal and sent the acceptance letter to the Jins that morning, and a formal intention of matrimony was announced publicly by them just a few hours back. Yanli had tried to cry herself to sleep, feeling trapped in her hopeless fate, but she couldn’t. She felt powerless for the first time as an omega, especially knowing how her future home would treat her. She was terrified.

“Shijie!” a voice whispered from outside her door, it made her smile through her foggy negative thoughts. But she didn’t respond, she watched as her door was pushed open quietly and the familiar figure of her favorite alpha slipped into the room, trying and failing adorably, to be stealthy. “Shijie, I know you aren’t asleep…” her A-Xian whined as he sealed the door close with one of his original talismans, which also prevented sounds from slipping out of the room. Now to the world, Yanli’s room would remain silent until Wei Wuxian himself removes it the next day when he leaves.

He smiled at her, lightening up her mood and the darkness in the room. Her heart felt lighter just by seeing that on him. Oh, how she loved this little devil of her. He has been hers since father brought him home. He was hers to nurture. He was glued to her side until Madam Yu intervened and pulled him away. But he found a way back, like today.

She loved him a little more than a sister or a caregiver should. She treated him differently. And it was obvious from the alpha pheromones that drenched the room, that that attraction was mutual.

“Come here A-Xian.” She raised both her hands towards him, beckoning him towards her. It would seem like she was asking for a hug, but she knew her brother understood when she was asking for it. 

A-Xian removed his clothes, not breaking eye contact with his beloved shijie, each layer revealing a little more of that firm body. Just seeing his clothes pile up on the floor was enough for her vagina to slick up in preparation for the incoming intrusion. He climbed onto the bed, and right into her arms naked as the day he was born. He pushed his face against her soft breasts, rubbing them against his face, Yanli sighed in relief that came with being intimate with an alpha. Her hand combed through A-Xian’s hair, holding him against her chest, and with practiced ease, she moved the single layer of her night robe that covered her breasts. Exposing them to her adopted brother, who didn’t waste a second to latch on and suckle like a baby.

Yanli moaned. She had been nursing A-Xian for the last 5 years, and in the last two years since A-Xian matured into his secondary gender, this act of nurturing had evolved into something more than just an omega caregiver feeding her alpha. 

Something more like the intimacy between mates.

She knew that her father was aware of the change in the arrangements, and also about their secretive nature. He never encouraged it, but he never stopped her nor A-Xian from entering her room at night. But it wasn’t an innocent acceptance. He turned a blind eye to their promiscuity because of his own unorthodox relationship with his senior disciple.

A-Xian’s insistent mouth made its way to the other breast, having already emptied the one she had given him. She smiled and lay on her back, letting the 18-year-old boy climb on top of her and claw at her nightgown until the knot came off and the front opened wide. A-Xian paused for a bit, sitting up, keeping minimum pressure on her hips as he placed his hands on the exposed part of her stomach and ran it up her body. Moving down and pressing his lips against her at the same time as his hands cupped her right breast. He shoved his tongue into her, and she moaned as his expert fingers played rough with her nipples. 

The kisses moved down her jaw, A-Xian kissing and sucking and biting everywhere he could, not hard enough to leave marks others would see tomorrow, but enough that there was a promise of it if she asked for it. He stopped when he reached her scent gland.

“Don’t do it. Say no to that Jin bastard Yanli.”A-Xian never used her name unless he was in his alpha state, the omega inside her rejoiced at the implication it held for her tonight.

“You know it isn’t my choice to make.”

“Let me mate you then.” A-Xian licked over her scent gland and then positioned his mouth as if he was going to bite. “Say the word and I’ll take you, right here right now. Make you mine and care for you for the rest of my life,” he promised. It was an alpha’s promise, he would keep it, she knew. But her mind went to a pair of golden eyes, and the white ribbon that was tied into her adopted brother's hair when he wasn’t like this with her. When he was with her, he left that token behind in his room, an unconscious gesture of not wanting to taint that sacred promise.

A-Xian was already to be married to the prestigious Lan omega. Lan Wangji. Yanli felt bitter, Wei Wuxian has been hers since the beginning, but she couldn't find it in herself to hate the man her brother looked upon with such adoration and respect. She had been there since the beginning, she had held him close, just like this as he poured his feelings towards him into her. She had comforted him, encouraged him, and celebrated with him at every step of that relationship. It was special to her, not just because it made her brother happy, but it showed her true unconditional love for the first time. And Yanli knew he would sacrifice his own engagement, his own happily ever after with his mate for her. And she wouldn’t let him take that decision.

Not her A-Xian.

She groaned through his ministrations, the fingers pumping inside at a steady rhythm, letting herself imagine life as A-Xian’s omega, allowing herself a moment of jealousy towards the Lan Wangji, before she gently pushed his head lower, towards her left nipple.

“This one is still full for you A-xian.” she sighed.

“Shijie…”

“My A-xian needs his milk so he can grow strong and healthy and protect the weak right?”

“Yes Shijie, your a-xian will become stronger soon.” and with that, his protests died down, as she had expected. 

She felt his heavy dick hot against her stomach, and she knew soon he would want more than just her milk. She spread her legs, and getting the cue, A-Xian moved up and between her legs. The ease with which the transition was made, not once unlatching himself from her nipple was proof of how many times this exact thing had happened. Too many to count.

And if she had it her way, she would never let him leave from his spot between her legs.

She reached between their bodies, taking the hard penis into her hands, pumping it absently, to the rhythm of A-Xian’s suckling. 

“Ah…” she moan at the bite her naughty brother gave her nipple before pulling off. Some residue mild dribbling down his mouth and onto her stomach as A-Xian expertly lined himself against she pussy and pushed himself into her in one thrust.

A-Xian started rocking his body gently against her. His face buried into her neck pressing kisses with every thrust of his hips,, one hand gripping her waist and her other kneading her boob. Yanli’s arms were wrapped around him, her bracket his hips, pressing her heels into his ass, making and urging him to go deeper.

And deeper her went. 

It still felt as perfect as the first time. Even though it had happened when the alpha was under the haze of his rut, when he had entered her, it felt like she was finally complete. It still felt like that to Yanli. She knew it was different with him, it had to be. She had been with others before. It was encouraged in the sect to seek out partners and experience things as long as you were safe about it. She had been fucked by younger and older men, experienced and inexperienced, in the comfort of her bed, and under the open sky of the training ground. But none of them fit her as her A-Xian did. They already had a strong emotional bond. But the sexual compatibility was there too. 

She had thought they would-be mates, it had broken her heart when Lan Wangji was chosen instead. But she got him like this at nights, until his marriage her alpha would suckle from her breasts, fuck knot her pussy, and cuddle her to sleep. She'll cherish it.

A-Xian pulled away, his hands pulling hers, crossing them over the other, squeezing her boobs together as he sat up straight. Looking straight at the motion. Her breasts had always fascinated him, even as a boy. One of her earliest memories she had with her adopted brother was him asking to use her boobs as cushions because of how soft they were. She would giggle at the memory if it weren’t for her mounting pleasure as the same person fucked into her with renewed energy. Each thrust sent her tits into a frenzy, and each time A-Xian became hungrier. 

He surged forward pushing lifting her ass from the bed, bending her backward as he pistoned into her from the top. Her boobs were now hitting her face with each gyration. Without warning, the orgasm hit her. She screamed as she felt the pressure peak and saw white. Her limp body willingly went with it as A-Xian pulled out, turned her onto her stomach, pushed her hips up, and thrust into her with renewed desperation. His naked body covered hers as his thrusts grew more and more frenzied. He felt him swell, and a spec of panic lodged in the pit of her tummy as she realized A-Xian wouldn’t be able to pull out before the knot this time, and she didn't want him to. That spec was obliterated when the knot finally breached past her entrance, making it difficult for A-Xian to pull out too much before thrusting in, but he kept thrusting as hard as he could, his hands squeezing her nipples between his two fingers, the pressure forced droplets of milk to ooze out and wet the sheets as she panted and moaned into the bedding, her back arching up. She felt her second orgasm build up just as the bulge of the knot moved deeper into her body. She couldn’t feel its path, how authoritatively it moved into her, claiming her walls as its own, painting them with her adopted brother’s potent seed. Had she been in her heat, this one knot would’ve been enough to make her pregnant with his pups. The thought pushed her over the edge a second time.

“A-xian…the knot…want to carry...your pups…” she mumbled, well aware of its incoherence, but she wanted to share its effects on her. She wanted to let the alpha know just what he was doing to her. 

A-Xian growled as he bit down on her shoulder. Well away from her mark, in a place that could be easily covered up with clothes, but the meaning remained the same. It was a claim.

Mine it screamed as his knot finally broke into her cervix and spurt semen into her. She felt the hot liquid inside, filling her up. A-Xian panted against her shoulder, still lying on top of her, covering her whole body. Her night robe still covered her back, the only barrier between her and A-Xian’s nakedness. But it was soaked through with sweat and slick. A-Xian kept a gentle motion with his hip, as he gently adjust the two joined bodies into a spooning position. He threw a possessive leg over her hip, and a hand cupped her breasts, gently kneading them as he absent-mindedly kissed from her neck to shoulder.

Two orgasms had made everything more sensitive. And she could still feel him inside her, the hot, hard, and pulsating dick was still filling her up. Maybe she would become pregnant like this, it wasn’t unheard of. And A-Xian was a strong alpha, she would be honored to be carrying his pups.

His hands wandered to her belly and gently rubbed it, her eyes followed the motion and stopped at the protrusion she saw there. Fascinated, she placed her hand above it and sighed in contentment when A-Xian placed his own above her. 

“Would it be so bad? Being mated to me? To be carrying my pups?” A-Xian’s hoarse voice whispered into her ears. “We could just run away. Just the three of us.”

“Three?” she asked, smiling. 

“You, Lan Zhan, and me of course. A family. A little unconventional, but not unheard of.” 

“Is that so?” she sighed. She knew it wasn’t, the Jiangs were examples of that. They both knew Madam Yu isn’t her birth mother. Jiang Fengmian had 2 mates, an alpha wife, and an omega husband. He bore Yanli, and died in childbirth, and Madam Yu bore A-Cheng. There was a rumor that A-Xian was her half-brother too, a result of an affair with the famed rogue cultivator Change Saren, though there was barely any similarity between her father and a-xian so she didn’t that was true.

Lying there in the dark, joined still but his knot, enclosed in the safety of his arms, and her belly full of his seed she allowed her mind to wander. To picture the life being A-Xian was offering. At her status, being a co-omega would be considered an insult. She wanted it so bad. It was A-Xian and Lan Wangji, they would never treat her with disrespect, they would take care of her and allow her to take care of them too.

“Yeah, Lan Zhan suggested it…in fact he…he is willing to be my second.” there was hesitation that Yanli recognized. She giggled. Her brother’s heart was set on Lan Wangji since the day they met, he had tugged the omega’s forehead ribbon then pretended to be ignorant of his actions when he was completely aware of its significance. And the fabled to be cold-hearted Lan Wangji had been the same, with his cute pink ears and a secret small smile. Yanli had been happy for them, for the happiness they had found in each other.

She would never take that away.

“No…I want that.” she spoke aloud, “I don’t want to be the main omega, I don’t wanna manage the household. I don’t want to be in charge. I want to be free.”

“Shijie…” A-Xian held her closer, tighter. “I would give you all that, anything. Just say yes.”

“I want to talk with my father, and then Lan Wangji first.” 

“Of course, I’ll ask uncle’s permission tomorrow morning. Lan Zhan is already on his way here with Xichen-ge and his husband.” 

“Oh?” 

“We wanted to have alternate plans ready in case there are any objections,” A-Xian admitted sheepishly. Yanli gave up her pretense of propriety and giggled. She intertwined their hands over her still protruding belly. 

“In that case, in the morning, I want you here, next to me. I want you to push your hardness into me even if I am still asleep. I want you to cum on my ass and leave me here with no blankets. Tomorrow, I want the whole Lotus pier to know that I have been soiled with. I want the Jins to know I am not the virgin omega my mother promised. I want them to know I have a suitor who has been defiling me right under my mother’s nose. I want the life you want to give me, I would be honored to share the rest of my life with you and Lan Wangji as my mates.”

“Shijie!” A-Xian buried his face in her hair. “No...my Yanli…mine forever.” he kept nibbling at the junction where one day she would proudly carry his mating mark. But not anytime soon, it would be at least six months after A-Xian and Lan Wangji were wed, maybe after Lan Wangji gets pregnant, as was proper. It would be a long wait but Yanli would be willing to wait for it if it meant being free. 

“There is another reason they are making this trip,” A-Xian mumbled in his sleep.

“Hm?”

“Lan Zhan is pregnant. We are to be married by next week. You won’t have to wait long for us.”

Yanli smiled, shaking her head and allowing A-Xian, soon to be her mate, to tuck her under his chin, settling down to sleep. Things had never gone as predicted since A-Xian entered her life. She had started lactating pre-maturely, given up her virginity outside of wedlock, and now she would be his concubine. 

Yanli absently mused over A-Cheng’s inevitable tantrum when it all comes to light tomorrow. But she was too exhausted right now to care. He’ll come around eventually, even if he doesn’t, she knows someone who will help. She drifted into a deep sleep while cooking up a plan to hook her brother up with the new member of their sect, whom he had been lusting after for weeks. Yanli knew she’d be okay with Jiang Cheng taking her virginity.

Early next morning, she felt a gentle rub of a hard penis inside of her. She moaned, not completely awake, but enough to direct her hand between her legs and rub herself while A-Xian continued his gentle thrusts.

“So close…Yanli…so good to me already. You’ll be perfect as my omega…so good.” he whispered. They both came together, and though a-xian didn’t knot her this time, he filled her up quite a lot. White liquid gushed out as soon as he pulled out.

“You sure this is how you want me to leave you Yanli? I want to clean you up.” he leaned over her and kissed her cheek, rubbing her arms as he waited. 

“Yes, I want this alpha.”

“Ugh, Yanli! I just came…” he whined. His hand pulled her back and started suckling again. When he was done with his morning drink, he gave her boobs an affectionate kiss, as if claiming them as his. And leaped out of bed. Yanli watched as he dressed up.

“Come here a-xian, let me do your hair.” Wei Wuxian went to her readily, handing her the comb and plonking on the floor.

“Lan Zhan will arrive in an hour, I need to talk to uncle about us before that. Hahaha, that old fuddy-duddy Lan Qiren is going to throw a fit, But don’t worry that is why we have recruited Xichen-ge. Did you know he is pregnant too? Yeah, it came as a shocker, for the Lans I mean. He hasn’t had his heat since getting married, which means he had been pregnant at that time, like our Lan Zhan…hahaha!! I knew they were fucking before marriage, Lan Zhan and I once walked into them fucking in the cold point in Clou Recessess, I wonder if that's where they got pregnant...omg old man Lan is going to lose it if he ever finds out how his favorite nephew used their scared healing pond omg!! hahahaha...But anyway, that gave me and Lan Zhan some courage to knot when he went into heat in the Xuanwu Cave, now we also are in the same boat. Hey, Yanli, do you think my seed is strong enough to get you pregnant in one knot? I don’t think females have to be in heat to start carrying pups am I right? It would be so cute with you two waddling around our house. So much work for me though. Imagine having two pregnant omegas to look after…”

Yanli smiled as she tied his ribbon in place. Humming at the right places as A-Xian kept on rambling. The sheet covering her nakedness had fallen off when she got up to do Wei Wuxian’s hair, and her perverted alpha used that opportunity to the fullest by kneading her ass and sucking on her milk as if was water. She fondly held him close. If after mating, it wouldn't be right to get pregnant at the same time as the co-omega. High strong hormones during pregnancy will make rational omegas jealous and suspicious. As much as she wants to see if it will take root, she knows she will have to take her contraceptives before the end of the day.

After he was all done and ready for the day, her alpha-to-be pulled her naked body against his for a deep kiss. It was different from those before. Wei Wuxian kissed her like a mate, and she felt herself getting wet again, her slick and his semen sliding down her thighs but they didn’t take it further. Yanli was left in her room, naked and marked with cum.

That is how her nanny found her a few minutes later as she came in to get the eldest Jiang Omega ready to receive her bridal gifts from the Jins. There was horrified screaming. Madam Yu came rushing in a few minutes later shouting at the top of her lungs. This attracted Jiang Cheng, who took in the messy state of the room and concluded -Wei Wuxian. He smiled and winked at her, and Yanli sighed in relief. It seemed like she had her younger brother’s blessing, she could hear him grumble ‘Wei Wuxian is better than that Jin brat’. 

Yes. Being his omega is going to be the best.
