A Pillowside Moon (Sisters ABO) - Chapter 4

After an Alpha knots, they cannot immediately pull out of an Omega’s body. Liu Changxi felt wave after wave of hot cum spraying against her cervix, scalding her so much that her waist trembled weakly. It felt both incredibly pleasurable and unbearably intense. Her whole body was numb and powerless; she could barely stay sitting properly on top of her sister.

Perhaps because it was the first knot, Sister had cum an unusually large amount. As Liu Changxi slowly recovered from her orgasm, she felt her belly swollen and burning hot. She couldn’t help lowering her tear-filled eyes to look at her own lower abdomen. The usually smooth and flat belly was now slightly bulging, as if it had been filled to the brim. The sight was utterly obscene.

Looking like this… it was almost as if Sister had fucked her pregnant…

The moment that thought appeared, an indescribable excitement rose in Liu Changxi’s heart. Her body reacted honestly as well. Her pussy, which was still spasming from orgasm, clenched tightly again, biting down even deeper on her sister’s cock.

Liu Chuhan’s knotted cock remained inside her sister’s body. This was the first time she had cum so intensely. While she was still dazed from the overwhelming pleasure, she suddenly felt her cock being squeezed even tighter. The greedy cervix sucked hard on her tip, sending a burst of numbness from the base of her spine throughout her entire body. Liu Chuhan shuddered and couldn’t help moaning, “Mmm…”

She subconsciously thrust her hips slightly, as if trying to escape the chase of pleasure, but in her daze she suddenly heard her sister’s soft, delicate moan.

Liu Changxi hadn’t expected her sister to suddenly thrust. The knotted cock was lodged completely inside her narrow, scorching pussy. Her cervix was already extremely sensitive from being creampied. Being suddenly pushed like that made the lingering pleasure surge back violently, nearly making her cry out again from how good it felt.

“Ugh… Sister, slower…” she whimpered pitifully, completely different from the wanton vixen who had been seducing her sister earlier. At a glance, she looked like nothing more than a fragile Omega being pinned down and fucked to tears by her own older sister. “You’re still cumming… wait a bit before fucking me again, okay… mmm… so much…”

Hearing her soft, obedient pleading, Liu Chuhan’s mind went blank for a moment. It felt as if the person who had been sitting on her demanding to be filled with cum wasn’t her sister. This soft, adorable appearance was her little sister’s real self.

Pure and charming off the bed, seductive and lewd on the bed—which one was the real her?

Liu Chuhan thought in a haze. Since her sister begged for mercy, she obediently stopped moving and waited for the long ejaculation to end.

Strangely, even though she had already knotted and cum, her rut should have eased slightly. Yet Liu Chuhan only felt her whole body burning hotter. Even her breath became scorching. Her brain was clouded by the high fever, making her thoughts unclear, but her body’s perception of the outside world grew sharper. She could clearly feel every squeeze and suck of her sister’s pussy around her knotted cock.

Normal rut reactions shouldn’t be like this… The only reason was the drug her sister had given her.

Liu Chuhan felt a headache coming on. She didn’t know what exactly her sister had drugged her with. A normal Alpha in rut wouldn’t be this powerless, pinned down by an Omega and unable to move.

Thinking of this, Liu Chuhan suddenly furrowed her delicate brows and bit her lip. A belated realization hit her—

In this state, could it be said that she had been raped by her own biological sister?

Liu Chuhan was startled by her own sudden thought, but strangely, she felt no disgust at all. Instead, she felt a vague excitement. Her cock inside her sister swelled even larger in response, making her sister start whimpering softly again.

“Ah… Sister got bigger again…” Liu Changxi gasped with her small mouth open as she was pressed by the hard cock. Her eyes were watery as she looked at her innocently. “Did you think of something? It’s so hard… mmm ah… the knot hasn’t gone down yet…”

Being asked like that brought Liu Chuhan’s hidden desires into the open. Countless images flashed through her mind, and her face instantly flushed.

At this point, Liu Chuhan could no longer avoid her deepest true desires. From the moment she had cum inside her sister’s womb, the moral shackles binding her had already cracked. Now, with a light push from her sister, those shackles completely shattered and could no longer restrain her.

Her body was telling her with utmost honesty — you like fucking your sister, you like the way she clenches and writhes around your cock, you like the sight of her belly bulging slightly when she takes your cock, you like her crying and cumming on top of you, you like her begging you to cum inside. You even like being pinned down and raped by her.

—You are hopelessly in love with her, even if this is incest.

Getting hard from a single touch from her sister, knotting so quickly inside her body, cumming continuously without wanting to pull out — every reaction of her body made Liu Chuhan realize that she truly craved incest with her sister.

Even ethics and morality could not stop her desire to unite with her sister.

The Alpha’s cool, gentle woody scent suddenly spread rapidly throughout the room. The rose scent that had dominated the space was gradually suppressed, and finally the two pheromones completely merged into one.

Liu Changxi smelled her sister’s pheromone, which had suddenly become many times stronger. Her already clearing mind instantly became hazy again. The gland at the back of her neck swelled, frantically releasing her own pheromones.

She had gone into full heat.

Her pussy, which had been basking in the afterglow of orgasm, began to itch unbearably. No matter how deep Sister fucked her or how much she came, it wasn’t enough. Her body craved more caresses, more kisses, more touches. She wanted to moan beneath her sister.

However, the knotted cock began to slowly shrink at this moment. Her body had already gotten used to being stuffed full. Once the knot subsided, an overwhelming emptiness rushed in. Liu Changxi could only instinctively clench her pussy tighter around the cock and even started twisting her hips to ride it again, unwilling to let it leave.

“Don’t… don’t pull out… give it to me…” Liu Changxi pleaded with a sobbing voice.

But her sister’s hands had already pressed on her waist. In her daze, Liu Changxi felt the world spin. In the next second, their positions were reversed. She was now pinned beneath her sister.

The Omega instinct to be possessed made her react strongly to her sister’s dominant position. The ache in her lower abdomen intensified, her cervix itched unbearably, and her whole heart longed for her sister to fuck her hard and claim her.

But Liu Chuhan did not do as she wished. She pressed her sister down on the bed and slowly but firmly began pulling her cock out.

Liu Changxi sensed her intention to withdraw and immediately clenched her pussy tightly to stop her. The delicate Omega, lost in desire, had lost her earlier dominant seductress energy. She could only wrap her soft arms around her sister’s neck and cry brokenly, “Sister, don’t go… please fuck me… don’t leave… you can fuck me however you want… don’t abandon me…”

Her sister looked so pitiful with tears in her eyes. Liu Chuhan felt both heartache and helplessness. She leaned down, gently kissed the corners of her eyes, and soothed her, “Baby, be good. Let me pull out first, okay? Sister won’t abandon you. Don’t be afraid.”

Liu Changxi looked at her timidly. “Doesn’t Sister feel good fucking me? Why do you want to pull out?”

Hearing her sister say “Sister fucking me” with such an innocent face, Liu Chuhan felt like fire was burning inside her body. Her Alpha instincts made her want to ignore everything and fuck her sister senseless, but her deep love and care for her sister kept her last shred of reason. She took a deep breath and explained gently, “I came so much inside you. If we keep going like this, Changxi will feel uncomfortable. So let me pull out first, okay? Sister will help you clean up.”

Liu Changxi didn’t say yes or no. She wrapped her arms around her sister’s neck, her fingertips sliding along her neck. Finally, she touched the swollen gland at the back of her sister’s neck and only then relaxed. She let out a soft “Mmm” and obediently loosened her pussy, allowing her sister to slowly pull out.

Liu Chuhan felt her touching the gland at her neck and didn’t know whether to laugh or cry. A swollen gland meant she was in full rut. At this point, even suppressants wouldn’t help. This little vixen, even with her brain turned to mush, still remembered to stop her from pulling out and using suppressants. Her intentions were truly deep.

That said, if it weren’t for the massive strength boost from a full-rut Alpha, she wouldn’t have the energy to pin her sister down right now. She’d probably still be lying there motionless, serving as a living dildo.

While mentally complaining, Liu Chuhan carefully withdrew from her sister’s body. Her size was quite large, and she was afraid of hurting her if she wasn’t careful.

Even though Liu Changxi had relaxed, the natural tightness of her pussy still made pulling out difficult. The slick walls clung densely to the thick length, creating indescribable friction and pleasure. Liu Chuhan suppressed the urge to thrust back in, bit her lip, and slowly pulled her cock out completely.

Liu Changxi moaned nonstop from the rubbing. She writhed restlessly beneath her. Liu Chuhan had to both prevent her sister from moving too much and restrain herself. By the time she finally pulled out completely, her fair forehead was covered in fine sweat.

Liu Chuhan breathed a sigh of relief. She brushed her sweat-dampened hair aside, gave her sister a light kiss on the lips, and said softly, “Sister will get a towel. Wait for me.” Then she got off the bed.

She returned with a clean towel, pursed her lips, and somewhat embarrassedly parted her sister’s long, slender legs. She said softly, “Sister will wipe you.”

Her sister was completely submissive, letting her do whatever she wanted. She obediently spread her legs, revealing her messy little pussy.

The pink pussy had turned a lewd crimson from the intense fucking. The hole stretched open by the thick cock hadn’t closed yet. It was slowly leaking thick white cum, but no matter what, it couldn’t all come out.

Liu Chuhan was greeted by this obscene sight and couldn’t help blushing. She was the culprit behind this scene. She had cum so much inside her sister’s belly, but because her semen was too thick, it couldn’t flow out easily. She would need to use her fingers to scoop it out.

Liu Changxi was tormented by heat and wasn’t obedient even while being cleaned. She kept moaning and whimpering, sometimes begging her sister to finger-fuck her, sometimes clenching around her fingers and grinding against them herself.

Liu Chuhan finally managed to clean her sister’s pussy after much entanglement with the little vixen. As soon as she tossed the towel aside, she heard her sister call her coquettishly, “Sister.”

Her sister often used this tone when acting spoiled. Liu Chuhan’s heart softened. She naturally leaned closer and asked gently, “What is it?”

Liu Changxi reached out and hooked her arms around her neck the moment she came close. Her fair, smooth legs wrapped around her sister’s waist, pressing their bodies tightly together.

“It’s already empty…” She smiled shyly yet seductively by her sister’s ear, breathing warmly, “You can fill Changxi’s belly again.”
