Stealing My Stepsister's Fiancée - Chapter 25

Chapter 25: Helping Her Differentiate

Su Yu, a little fledgling who hadn’t even held an Omega’s hand, was completely unequipped to handle such a situation. Upon hearing those words, she reacted like a startled rabbit, pushing Ni Hezhi away in a panic, clumsily gathering her disheveled clothes.

In the struggle, her arm brushed against the Omega’s back, and her sleeve became stained with a red, unknown substance.

Something seemed… amiss.

Su Yu rubbed her cuff. It was a lipstick mark.

It turned out that Ni Hezhi’s “mosquito bites” were all “made up.”

She had fallen for her trick again!

Su Yu was angry at herself for being so easily manipulated, yet she was helpless against Ni Hezhi. Her muffled voice held a hint of compromise: “You always trick me.”

Ni Hezhi’s eyes and brows were filled with joyful amusement: “It’s not that I always trick you, but that you always believe me.”

“My mother says the most important thing for a girl is beauty. I would never let myself have even the slightest flaw.”

Ni Hezhi subtly curved her lips, her eyes fixed on Su Yu. Her slender white fingers pressed against the bed, approaching her with a feline grace.

Two full, sweet peaches swayed with her movements, creating enticing curves.

Su Yu nervously dodged backward, shrinking until she was pressed against the furthest wall of the bed, her back against the wall with nowhere left to retreat. Her cowering posture resembled a fragile white flower being bullied by a villain.

Ni Hezhi’s desire intensified at the sight. She hooked her arm around Su Yu’s, boldly straddling her bent legs, and sweetly cooed, “Why are you hiding from me? Are you angry?”

Ni Hezhi’s fingertips hooked her clothing hem, swaying it back and forth gently: “Don’t be angry with me, okay?”

A celestial beauty, when she acted coquettishly, could melt anyone’s heart. Su Yu had no anger left, only an undeniable, surging tide of desire.

“Xiaoyu, let’s do it once…” The Omega whispered into her ear.

Su Yu averted her gaze, trembling violently, fine beads of sweat breaking out on her forehead.

Ni Hezhi raised a hand to wipe away the sweat from Su Yu’s temples, chasing her restless gaze: “Xiaoyu, look at me…”

Su Yu didn’t dare to meet her eyes, her face consistently turned away. She accidentally caught sight of their intertwining silhouettes on the wall, rising and falling, hot and entwined.

The sexually charged scene made Su Yu too shy to speak. She pushed the Omega, but it was merely symbolic, without any real force.

Ni Hezhi felt the softening in Su Yu’s heart. She moved slowly against her, carefully probing: “What is Xiaoyu afraid of? Do you not like me? Is that why you’re unwilling to do it with me?”

“I… we…”

Su Yu was incoherent, wondering why Ni Hezhi was doing this to her. Did she treat others this way too, casually getting into bed with people?

As she thought about it, an inexplicable tightness welled up in her chest: “Omegas shouldn’t casually… casually do it with people…”

“Not even with me?” Ni Hezhi’s voice was soft and gentle, infused with a seductive, enchanting charm: “I’ll only do it with you, okay?”

Su Yu neither agreed nor disagreed, but her gaze no longer flinched. She looked back shyly, her eyes concealing a hidden delight, making her beautiful peach blossom eyes appear even darker and brighter.

It was too much!

Ni Hezhi’s heart ached with desire, especially when Su Yu pursed her lips, looking incredibly innocent.

She really wanted to kiss her.

Thinking it, she did it. Ni Hezhi reached out and tucked Su Yu’s slightly damp hair behind her ear, stroking the back of her ear, slowly moving her hand back, her fingers intertwining with Su Yu’s hair.

“Xiaoyu, let Jiejie teach you how to kiss first.”

Before Su Yu could react, the scene before her suddenly shifted. She was unexpectedly pushed onto the bed by Ni Hezhi.

The next second, a soft, fragrant body covered her, hands gripping her shoulders, a provocative, reckless intensity in her movements.

Many years later, Su Yu would still remember this night: the stuffy, dilapidated little room, the creaking of the old ceiling fan, the intoxicating scent lingering in her nostrils.

She would remember that—

A kiss as soft and sweet as a cloud.

Ni Hezhi initially just gently pressed her lips, afraid of repelling Su Yu. She tentatively brushed against her chin, then slowly moved to the corner of her lips, gently caressing them.

At that moment, Su Yu felt her entire body floating in the air, dizzy and unsure where she was drifting.

The Omega’s lips were so soft, so sweet.

Su Yu remembered her childhood, when her parents were still alive. During busy farming seasons, she would help out in the fields. Her father would lovingly pat her head, telling her to sit on the field ridge and read. A hawker selling ice cream would pass by the field, and her father would wave him over, spending two yuan to buy a cream cone and hand it to her.

She would tilt her small face up, lick the ice cream, and feel a sweetness that reached her heart.

That feeling was truly so happy, so satisfying…

Su Yu dared not breathe, afraid that the sound of her own heartbeat would melt the sweetness between their lips.

She didn’t even know what to do. She had never kissed a girl, only glimpsed kissing scenes briefly in Miao Hailu’s secretly kept yuri films. Su Yu dared not move, her hands lying flat at her sides, every knuckle tense, nowhere to rest.

Sensing her inexperience, Ni Hezhi parted their joined lips and instead caressed her face.

Su Yu’s cheeks were flushed like maple leaves, and she breathed shallowly, looking at the Omega’s eyes with a rare bewilderment.

So innocent…

Ni Hezhi loved this expression to death. Beyond her happiness, there was a hint of surprise, because she realized that Su Yu hadn’t pushed her away, letting her kiss her for so long.

Just a moment ago, she had been annoyed by Su Yu’s reluctance to respond, but now Ni Hezhi felt utterly content.

The little airhead let her kiss her; what more could she ask for?

“Su Yu…” Ni Hezhi once again took her lips into hers, biting gently: “When you kiss, you should close your eyes.”

“Also, a kiss counts only if you use your tongue.”

Ni Hezhi rubbed against Su Yu in her arms, her eyes full of charm fixed on her: “Xiaoyu, come find Jiejie’s tongue, okay?”

Amidst ragged breathing, Su Yu looked at Ni Hezhi with a hazy gaze. From the first day they met, she had thrown out tempting bait, and Su Yu wanted to take it, but didn’t dare.

She wasn’t worthy of her.

That day, when Ni Hezhi stepped out of the off-road vehicle, Su Yu looked at her own cloth shoes with exposed toes and knew that Ni Hezhi was an unattainable dream.

What right did she have to harbor fantasies?

Seeing Su Yu’s prolonged hesitation, Ni Hezhi gently cupped her face, her soft lips kissing along her neck to her cheek, stopping at the corner of her lips, finally handing over the initiative to Su Yu.

“Xiaoyu, kiss me!”

The soft, sweet scent was too alluring.

It was truly irresistible.

Su Yu lowered her head. She didn’t kiss, but merely followed the rich scent, lightly touching the Omega’s chin.

Just once, then quickly pulled away.

This “almost kiss” type of tentative interaction was even more provocative.

Ni Hezhi couldn’t help but wrap her arms around Su Yu’s neck and kiss her again. Their bodies pressed together, perfectly aligned, their intertwined shadows on the wall almost merging into one.

Outside, the rain still pattered down, occasionally accompanied by thunder. Inside the dim little room, the Omega’s intermittent moans lingered.

Soft tongues entwined, Ni Hezhi’s body temperature rapidly climbed. She was now fully in heat, her cheeks flushed, her hazy eyes watery, the bedsheets beneath her wet with a transparent fluid.

When their lips parted, a precarious strand of liquid still clung to the Omega’s lips. Her swollen lips, kissed raw, were more enchanting and decadent than peonies.

Su Yu lowered her head, gazing at the Omega in her arms, her heart utterly collapsing. A tiny spark of courage, aided by this sliver of light, quietly took root in the deepest, most secret corner of her heart.

She unconsciously wanted to wipe away the moisture from the corner of the Omega’s mouth, but as she reached out, she hesitated, unable to control her timidity.

Just as she trembled and recoiled, Ni Hezhi suddenly grabbed her hand, using that slight force to wrap it around her neck, and in the ambiguous breathing, whispered: “Xiaoyu wants to touch Jiejie, why won’t you?”

Ni Hezhi couldn’t believe she was being a hypocrite. She expected others to maintain boundaries with her, but with Su Yu, she just wanted to be close.

She could do anything.

She rubbed her nose against Su Yu’s face, her voice growing more entwined: “Xiaoyu can touch any part of Jiejie’s body…”

Su Yu’s fair face flushed with shyness.

A strange heat surged in her chest, gradually spreading through her limbs and bones.

Burning intensely into her brain.

As if possessed, Su Yu raised her hand and caressed Ni Hezhi’s cheek, her thumb lingering on her jawline, then sliding to the corner of her lips, gently wiping away the moisture.

Outside, lightning flashed and thunder roared. The light in the room was dim. Su Yu simply gazed at Ni Hezhi, her skin, whiter than frost and snow, smooth as silk, her slightly parted, tempting red lips, her long, graceful swan neck, and gradually further down… her perspiring collarbone, a few damp strands of hair clinging to her peaches, a scene of utter decadent beauty.

Su Yu thought, how long would it take her to forget how she looked at this moment…

She couldn’t forget, how could she forget…

This was the first time Su Yu had openly admired an Omega’s bare body. Before, she wouldn’t have dared to stare so directly. With her heart racing out of rhythm, she subtly pursed her lips, telling herself to avert her gaze, but her eyes stubbornly refused to obey.

Ni Hezhi noticed the change in her expression, a hint of playfulness flashing in her eyes. This airhead was like a sealed jar, requiring deadly force to open.

She took the opportunity to hook her arm around Su Yu’s neck, her gaze falling on Su Yu’s still-undeveloped scent gland on the back of her neck, and softly tempted: “Xiaoyu, Jiejie will help you differentiate, okay?”

Su Yu’s heart involuntarily stirred. She saw herself reflected in Ni Hezhi’s pupils, and felt a faint sense of anticipation.

Ni Hezhi naturally sensed it too. Her fingertips caressed Su Yu’s face, continuing to entice her ear: “Grandma said Xiaoyu wants to go to university in Bincheng…”

“Then does Xiaoyu know that the Alpha Girls’ School in Bincheng doesn’t charge tuition or miscellaneous fees? Even food and accommodation are free, and you get a living allowance every month.”

How could Su Yu not know about the privileges of an Alpha Girls’ School? But she was already eighteen. Most people differentiate by this age, becoming either an Alpha or an Omega, or at least a Beta. Yet, she had shown no signs of change.

Grandma was frantic. She gritted her teeth and sold the family’s piglets, then forcibly dragged Su Yu to the provincial city to see a doctor.

Su Yu still remembered that day’s events: the elderly doctor stared at her scent gland cell X-rays for a long time, his expression grave: “Your condition is a rare differentiation disorder, with an incidence rate of about one in a hundred thousand. Current medical levels cannot intervene.”

“However, there was a case in S Nation where a patient’s situation was identical to yours. She survived a plane crash during a trip with an Omega on board. The two were stranded on a deserted island for half a year, and later successfully differentiated into Alphas, which was a medical miracle.”

“Afterward, biologists in S Nation studied the two and found that the Omega was of a very high rank, with a rare pheromone – sage – which could cause hallucinations and excitement, playing a crucial role in promoting Alpha differentiation.”

“So, I suggest you live with a high-ranking Omega for a period of time. It would be even better if there’s pheromone assistance, like wormwood, tonka bean, catnip, sage, peyote, poppy, datura, henbane… these pheromones all have aphrodisiac and mind-affecting properties that can help you stimulate your glands to promote differentiation.”

At the end, the old doctor looked at her intently: “However, high-ranking Omegas with rare pheromones are extremely rare, accounting for only one ten-thousandth of the total population worldwide…”

“Based on privacy and security considerations, hospitals generally do not retain personal information for these types of Omegas, although there are specialized private agencies…” The old doctor seemed to hesitate, about to say more: “As a doctor, I can only say this much. The rest is up to you.”

Upon hearing this, Su Yu felt utterly disheartened and gave up all hope.

High-ranking Omegas were already scarce, let alone those with rare pheromones. They were mostly from prominent families, more sought after than female celebrities on TV, desirable marriage candidates for wealthy families. How could they possibly come to this impoverished backwater to help her differentiate?

Moreover, the “private agencies” the old doctor mentioned, since they specialized in such business, must be profit-driven and take huge risks, so their fees would certainly be exorbitantly high.

She was still struggling to make ends meet; how could she afford such an agency?

Su Yu was lost in thought when she suddenly felt her hoodie zipper being pulled open. In her panicked and embarrassed gaze, Ni Hezhi leaned over and gently pulled the hoodie further down.

Su Yu’s hoodie was pulled open, revealing her smooth collarbone. Her fair neck and sides were covered in scars of varying depths, clearly marks formed by repeated friction and scabbing from heavy objects.

Su Yu was terribly ashamed. Remembering Ni Hezhi’s remark, “I would never let myself have even the slightest flaw,” she couldn’t help but feel a renewed sense of inferiority.

Her scars were hideous and ugly. She expected Ni Hezhi to show a look of disgust, or casually say something like “ugly.”

But, there was nothing.

Ni Hezhi simply gently caressed a few of her scars, her eyes wet and soft.

She asked, “Does it hurt?”

Su Yu saw the heartache in her eyes, and her chest swelled with warmth: “No, it doesn’t.”

Ni Hezhi’s voice choked: “You had a very difficult childhood, didn’t you?”

Su Yu shook her head. She had never felt her life was hard. Being able to support her grandmother and sister with her own hands made her feel grounded and content.

Ni Hezhi came from a privileged background, surrounded by Alphas who were mostly wealthy and noble scions. Precisely because she had witnessed the extravagant lifestyles of young masters and ladies, she found the poor but resilient Su Yu to be so precious.

Ni Hezhi leaned down, her lips imprinting a kiss on the scar at the back of Su Yu’s neck. Gradually, not only her neck, but her collarbone and chest were also solemnly caressed by the Omega’s lips.

This feeling… it was simply maddening!

Su Yu felt as if she were being consumed by fire, her body trembling like a sieve. Something seemed to be seeping from her glands, causing a throbbing pain.

She braced her hands, trying to sit up, but her lips accidentally brushed against the fragrant tip of the Omega’s peach.

Su Yu’s face flushed crimson with embarrassment.

Ni Hezhi, however, was utterly charmed. She held Su Yu’s shoulders, pressing her back down, and let out a light, seductive chuckle: “Xiaoyu, don’t rush. Jiejie will teach you how to ‘eat’ first… then it’ll be your turn.”

Su Yu was too abashed to speak. She panted rapidly, looking up at Ni Hezhi through her disheveled hair. Perhaps due to shyness, her beautiful peach blossom eyes were veiled with a mist, like a little deer unversed in worldly ways.

Ni Hezhi admitted, she was captivated.

She subtly lowered her gaze, her eyes falling on Su Yu’s chest.

Su Yu’s handmade undershirt had slipped down during their struggle, revealing everything below her neck.

But she didn’t notice it herself; the exposed view fell entirely into Ni Hezhi’s eyes.

She hadn’t expected the little airhead, who looked so slender and flat, to be so alluring beneath her clothes.

The color was very pink, small and delicate, like pink snowflakes falling on cherry blossom petals.

Ni Hezhi couldn’t help but think of the ancient, leafy tree in the backyard of the old mansion. She didn’t know its species, but every autumn, it would be covered with tiny green fruits.

They were also small like that.

The head chef in the kitchen would occasionally pick some to make wine. Perhaps because the fruit tasted tart, the wine brewed wasn’t as sweet as grape wine. Ni Qingyao disliked the taste, but Ni Hezhi found it refreshing and often asked the kitchen to prepare a small glass after meals.

Ni Hezhi gazed at the small fruit before her and wondered: would this one taste the same?

She leaned down and gently blew a breath onto the unripe fruit.

Su Yu’s entire body trembled violently, her pupils suddenly widened, and she hastily pulled up the blanket to cover herself.

“Ni, Ni Hezhi~ don’t~”

“Don’t call me by my full name,” Ni Hezhi pulled the blanket away, her gaze lifting with an alluring charm: “Xiaoyu, call me Jiejie.”

Su Yu remained silent, her expression both ashamed and stubborn. She didn’t know why Ni Hezhi always liked doing this to her, yet she didn’t dislike it at all; she even harbored some hope, hoping that Ni Hezhi would get closer to her, be intimate with her.

Ni Hezhi took in her expression, a mischievous smile blossoming at the corner of her lips.

Unwilling to call her Jiejie?

It didn’t matter, she had plenty of tricks to make Su Yu surrender.

Another warm breath wafted over, and the sleeping fruit quickly perked up with excitement.

This honest physical reaction was something even Su Yu herself hadn’t anticipated.

Ni Hezhi naturally wouldn’t miss this sight, and she chuckled softly: “Xiaoyu here… really likes Jiejie.”

Ni Hezhi’s physical actions weren’t enough; her verbal teasing was relentless. Su Yu felt her face growing hotter and hotter. She opened her mouth to stop her, but in the end, nothing came out.

When Su Yu didn’t speak, Ni Hezhi took it as her unspoken consent. So she blew another breath as if rewarding her, and Su Yu couldn’t hold back, a shallow groan escaping her throat.

Ni Hezhi lifted her face, her voice shimmering with triumph: “Xiaoyu, you’re so sensitive.”

Su Yu bit her lip tightly, her head turned to the side, letting out a pitiful whimper, like a small animal caught in a trap, helplessly crying out in the hunter’s hands.

She looked utterly bullied.

Seeing this made Ni Hezhi’s heart flutter. How could this person be so cute? She played with the two shy little fruits with even more gusto.

Su Yu was terribly ashamed, gripping the bedsheet with both hands, her ears so red they looked like they might bleed: “You… don’t be like that.”

“Like what?” Ni Hezhi nestled against her neck, her smile as vibrant as a peach blossom: “Xiaoyu, has anyone ever told you your voice is very nice? Especially when you… pant?”

“Call me Jiejie… Jiejie won’t bully Xiaoyu anymore.”

“I, I don’t want to…” Su Yu’s lips were white from biting them. Her chest felt hot and itchy, yet also very comfortable. She hadn’t known that part of her could feel this way.

“Don’t want to?” Ni Hezhi slowly curved her lips, very slowly leaning down again, pinching Su Yu’s beautifully sculpted jawline, and whispered: “Don’t want what? Don’t want to call me Jiejie, or don’t want me to do this to you?”

“Don’t… don’t blow on me… Mmm~”

Yet that disobedient “seductive wind” blew from left to right, making the two fruits sway back and forth.

Su Yu gasped.

Her peach blossom eyes were misty, gazing at Ni Hezhi with a mix of restraint and helplessness.

Ni Hezhi suddenly felt a mischievous urge to bully her relentlessly, to make her cry.

For no particular reason.

Just because Su Yu’s peach blossom eyes would look so beautiful when they turned red.

Ni Hezhi suddenly bit the small fruit, muttering indistinctly: “I’m not blowing anymore… So, Xiaoyu, do you like this?”

“Jie, Jiejie~” Su Yu couldn’t take it anymore, her voice containing a hint of begging, a strategic retreat: “Jiejie, don’t bite.”

Her voice was soft, husky, and tickled Ni Hezhi’s heart.

Ni Hezhi’s heart trembled at her incredibly contrasting “Jiejie.”

She actually called her Jiejie.

The usually dull little airhead actually obediently and softly called her Jiejie! And in such an alluring way.

She absolutely loved Su Yu’s confused and emotional state. She was like a different person from her usual cool and reserved self. It made her want to bully her even more, to see more of her uncontrollable expressions.

And… do some things a Jiejie should do.

Ni Hezhi raised her hand, smoothing Su Yu’s damp, disheveled hair behind her ear, and slowly asked: “Xiaoyu, are you hot?”

“Mmm, so hot…” Su Yu’s eyelashes trembled, and a glistening bead of sweat slid down her cheek.

Even without experience differentiating, Su Yu could feel something was wrong with her body, especially when she smelled Ni Hezhi’s scent. Her entire body would inexplicably heat up, even her bl00d would boil. The scent gland on the back of her neck was particularly hot. She felt as if she had a high fever, the heat making her head swim and flushing her face pink.
