A Pillowside Moon (Sisters ABO) - Chapter 13

Liu Chuhan’s gaze remained fixed upon her sister’s glistening pussy as its entrance gently opened and closed, yet she did not immediately move. She seemed to be contemplating something.

“Sister?”

Noticing where Liu Chuhan was staring, Liu Changxi felt the humiliation of having her most intimate place completely exposed spread throughout every part of her body.

Yet it only brought her greater pleasure.

“Take it out for me… It aches so badly inside…”

Her words sounded simultaneously like temptation and invitation. As she spoke, she shifted her waist and hips forward, giving her sister easier access to remove the vibrating egg.

With her mouth, naturally.

The toy had not been switched off and continued buzzing inside Liu Changxi’s delicate pussy.

Liu Chuhan’s breathing became uneven. She knew the controller was in her hand and that a single press would allow her to stop before things went any further, ending this absurd sexual encounter.

Yet her finger showed no intention of pressing the button.

It seemed that she, too, wanted them to continue.

To continue having sex with her sister.

To continue entwining their bodies with abandon.

To continue possessing Liu Changxi.

As the flames of desire intensified, those thoughts grew increasingly clear in Liu Chuhan’s mind. She could not resist the longing emerging from the depths of her soul.

As though beyond her control, one hand settled upon her sister’s smooth thigh, and she slowly lowered her head between Liu Changxi’s legs.

Liu Chuhan knew perfectly well that once she lowered her head, there would be no turning back.

Nevertheless, her body honestly obeyed the command buried deepest in her heart. Before she realized it, her lips had already touched her sister’s soft entrance.

Liu Changxi had released far too much fluid. Liu Chuhan first had to lick away some of the abundant juices. Only then did she extend her tongue gently into the soaked slit and hook it around the short cord.

She caught the cord between her teeth and slowly began pulling it outward.

“Mmm…your tongue is so hot…”

Being served by her sister felt wonderful. Liu Changxi narrowed her eyes slightly and panted in a spoiled voice.

“It aches…uhn…slowly, Sister…”

The intense fragrance of roses made Liu Chuhan burn all over. The cock her sister had freed throbbed painfully hard, craving Liu Changxi’s touch.

Liu Chuhan restrained her Alpha instincts and merely tightened her arms around her sister’s legs, her mouth remaining exceptionally gentle.

The vibrating egg was still moving, making it difficult to control. Liu Chuhan could not exert much strength while holding the cord between her teeth, while her sister’s pussy clenched around the toy extraordinarily tightly.

As though unwilling to let the toy tormenting it leave, the entrance contracted with reluctance. Every time Liu Chuhan managed to pull it out slightly, the greedy pussy swallowed it again and concealed it completely.

After several unsuccessful attempts, fine perspiration appeared at Liu Chuhan’s temples. Meanwhile, her sister continued moaning shamelessly as though determined to make the situation even more chaotic.

Liu Chuhan closed her eyes. She released the cord and raised her head, looking at her sister with helplessness.

Meeting her gaze, Liu Changxi acted as though she knew nothing.

“Why did you stop, Sister?” she asked innocently.

Liu Chuhan pressed her lips together and sighed.

“You…need to relax…”

Liu Changxi smiled as though her plan had succeeded, but her tone remained exceptionally innocent.

“Where do you want me to relax, Sister? I won’t understand unless you explain clearly.”

Her sister was doing this deliberately. Liu Chuhan understood that perfectly.

She had always been reserved, and asking her to say such words aloud was unbearably humiliating. But she had spoiled her sister long ago. Liu Chuhan knew that if she did not satisfy her today, Liu Changxi would never release her so easily.

The pheromones in the air grew increasingly concentrated. Liu Chuhan could feel the scent gland at the back of her neck gradually swelling.

Although she had not yet entered a full rut, she was not far from it. If Liu Changxi continued delaying, even Liu Chuhan did not know what she might do.

It would be terrible if she injured her sister.

With that thought, Liu Chuhan finally sighed and obediently yielded. Her face turning red, she struggled to say, “Changxi’s…pussy…needs to relax a little…”

Liu Changxi smiled radiantly. “I’ll listen to Sister.”

With that, she relaxed her muscles and stopped deliberately sucking and clenching around the vibrating egg.

Yes, she had done it intentionally.

She had deliberately prevented her sister from removing the toy and forced Liu Chuhan to voice her request.

Her sister was so dishonest about her desires that Liu Changxi was determined to make her confront them.

The vividly colored entrance blossomed slightly.

Liu Chuhan’s ears became completely red. No longer willing to let her sister prolong her torment, she lowered her head, caught the cord between her teeth, and pulled backward.

This attempt went exceptionally smoothly—so smoothly that when the vibrating egg slipped from Liu Changxi’s pussy, it produced an unmistakable sound.

Pop…

Obscene and enticing.

Seeing her sister seemingly frozen, Liu Changxi brought her legs together and concealed her juice-drenched pussy.

She sat upright, placed one hand upon her sister’s shoulder, and removed the vibrating egg still hanging from Liu Chuhan’s mouth with the other.

Her gaze traveled downward. She suddenly raised an eyebrow and smiled.

“Sister…you’re so big.”

The cock that had once been embedded deeply inside her body now stood completely erect. A little pre-cum had even emerged from its tip because of Liu Chuhan’s overwhelming desire.

Liu Changxi tossed the vibrating egg aside and used her free hand to caress her sister’s cock.

Her voice teasing, she asked, “You’re this hard… What do you want to do, Sister?”

Liu Chuhan bit her lip, a faint blush covering her face. She allowed her sister to play with her but refused to say another word.

She had already spoken something so embarrassing once. Her thin skin could not withstand being forced to do it again.

“You won’t tell me?”

Liu Changxi was not surprised by her sister’s silence.

She gently stroked Liu Chuhan’s cock, occasionally brushing her fingertips across the sensitive urethral slit. Each touch drew another uncontrollable gasp from Liu Chuhan, the sounds becoming exceptionally seductive inside the silent office.

“If you refuse to tell me, you’re not allowed to cum, Sister.”

As she spoke, Liu Changxi abruptly pulled her sister onto the sofa and pinned her down.

The sofa was spacious. Liu Changxi positioned herself between Liu Chuhan’s legs, braced one hand beside her waist, and closed the other more tightly around the thick cock.

Her stroking suddenly accelerated.

“Uhn…don’t…”

With her cock controlled and played with by her sister, Liu Chuhan was reminded by the tightening hand of Liu Changxi’s narrow pussy.

She remembered how she had stretched open her sister’s tight passage and how she had thrust relentlessly inside her body.

The psychological stimulation drew out even more intense pleasure, making Liu Chuhan involuntarily pant.

“Mmm…too fast…”

“Too fast?”

Liu Changxi continued stroking her sister while removing the trousers that no longer concealed anything.

Seeing the wet patch her own juices had left upon them, she smiled knowingly.

“But you fucked me even faster than this before, Sister. Have you forgotten?”

She leisurely pulled off Liu Chuhan’s trousers while speaking shamelessly.

“You fucked me so quickly and forcefully. You refused to stop even when I cried and begged for mercy. It must have felt wonderful, didn’t it?”

Her words made Liu Chuhan remember how she had lost control during her full rut and fucked her sister like a madwoman.

She had pounded Liu Changxi until the shape of her cock appeared through her belly. She had ejaculated so much that her sister’s pussy could not hold it all, leaving the entrance pitifully red and swollen.

It had been too rough and too insane…

And far too intoxicating.

Liu Chuhan released a tormented gasp and unconsciously moved her hips, only for her sister to pin her waist firmly against the sofa.

A warning immediately followed.

“Don’t move.”

The friction against Liu Chuhan’s cock abruptly stopped.

Dazed and confused, she raised her eyes toward her sister. Liu Changxi narrowed her eyes and parted her red lips.

“I’m allowed to touch you, Sister, but you’re not allowed to move. This is your punishment.”

Punishment for refusing to acknowledge her true desires.

Liu Chuhan bit her lip, feeling embarrassed and humiliated. She wanted to escape but feared genuinely angering her sister.

All she could do was nod with a flushed face while involuntarily gripping the sofa beneath her.

“Don’t cum, and don’t move.”

Liu Changxi leaned forward and kissed her sister, smiling seductively.

“You must remember that clearly, Sister. Otherwise…”

Liu Chuhan knew her sister was deliberately keeping her in suspense, yet she still willingly fell into the trap.

“Otherwise what?”

Liu Changxi hooked her finger beneath the thin shirt and pulled it completely open, revealing the soft breasts contained within a white bra.

Her expression delighted, she answered, “Otherwise, I’ll make you cum until you can’t get hard for three days.”

Then this proper, serious office would be covered everywhere in her sister’s semen.

Merely imagining such a scene made Liu Changxi’s legs weak with excitement. She could hardly wait to see her sister lose control and ejaculate.

As she stroked the increasingly thick, rigid cock, another thought occurred to her.

Would using her mouth stimulate Sister more intensely than using her hand?

She acted upon the thought immediately.

While Liu Chuhan’s eyes remained clouded by her caresses, Liu Changxi suddenly lowered her head and extended her soft tongue, licking the tip of her cock.

“Ah!”

Something warm and wet swept across Liu Chuhan’s most sensitive spot.

A tingling current raced along her spine and invaded her mind. She released an uncontrollable moan, her entire body becoming rigid.

She nearly ejaculated immediately but remembered her sister’s command and desperately endured it.

Her mind remained blank for several moments before she finally comprehended what had touched her.

Her sister was licking her.

Realizing this, Liu Chuhan hurriedly looked down. Sure enough, Liu Changxi was holding her cock and studying it as though considering how best to put it in her mouth.

“Don’t!”

Liu Chuhan immediately retreated, trying to move her hard, swollen cock away from her sister.

How could she allow her sister’s mouth to touch such a place?

She felt humiliated and ashamed.

But Liu Changxi firmly held her down. Her delicate brows furrowed with displeasure.

“I already told you that you’re not allowed to move, Sister.”

“But…” Liu Chuhan opened her mouth, attempting to negotiate. “Could you…please not use your mouth?”

“Why?”

Confused, Liu Changxi rubbed the head of her sister’s cock.

“Doesn’t it feel good?”

Liu Chuhan sharply inhaled. Her body trembled uncontrollably, and she shyly looked away, pressing her lips together without answering.

“If you refuse to answer, I’ll continue.”

Liu Changxi would not waste any opportunity to force her sister to speak honestly. She resumed stroking Liu Chuhan’s cock and lowered her head suggestively.

“You have to tell me the truth, Sister.”

Liu Chuhan genuinely did not want her sister to give her oral sex. Yet Liu Changxi controlled her body and had forbidden her to move.

Seeing that her sister truly intended to use her mouth again, Liu Chuhan could only suppress her humiliation and whisper, “It…feels good…but I don’t like it…”

Liu Chuhan had occasionally watched porn during her life. The Alphas in those videos had always been somewhat rough, and their Omegas appeared uncomfortable while giving them oral sex.

She disliked a sexual act that seemed so degrading. She especially did not want her sister to endure discomfort merely to pleasure her.

Anything Liu Changxi did would feel good to her. There was no need for oral sex.

“I see…”

After listening to her sister’s hesitant explanation, Liu Changxi blinked and suddenly lowered her head to lick the cockhead again.

Liu Chuhan immediately trembled, her breathing becoming rapid. The stimulation brought tears to her eyes.

She demanded in frustration, “Didn’t you agree that you wouldn’t do this if I told you the truth?”

“Hmm? Did I say that?”

Liu Changxi gently kneaded the cock she had tormented in every possible way and curved her lips into a smile.

“I said I would continue if you refused to answer. I never said I would stop after you answered.”

Her seductive gaze swept across her stunned sister. Her expression remained soft and alluring, but her words were exceptionally commanding.

“Your cock is mine, Sister. I’ll suck it however I please, and you’re not allowed to resist.”

After asserting her control, the Omega lowered her head provocatively.

Ignoring the Alpha’s pitiful struggle, she took the smooth, rounded cockhead into her mouth.

The disheveled Alpha whimpered and began moaning softly as her own younger sister sucked her.
