Lust System: Harem Of Beautiful Women

Chapter 164: Big Sister, Hurry Up!

”Do not worry, I will not peek at your password.”

Luis lay beside her and said jokingly.

”Who is afraid of you looking? I am so poor I have to sell my blood. It is all debt, not a single cent left in the balance.”

Nancy had relaxed, and her state was no longer so extreme and awkward. She said coquettishly, ”Your card is full of balances, my card is all negative numbers.”

They were almost lying together. Physical contact was already obvious, separated only by the nightgown, but it was intimate enough.

Luis placed a hand on the small of her back. Nancy shuddered all over but did not stop him. Luis took the opportunity to blow hot air into her ear and said, ”Big sister, is it not hot wearing a bra? Even with the air conditioning, it must feel stifling.”

As he spoke, Luis pressed his advantage and moved closer. After hugging her, he began kissing her ears, saying, ”Let me help you take it off.”

”It is a magic clasp. You know how to work it too?”

Nancyʼs face already had a faint blush. She tried hard to keep her tone steady. ”Lily does not wear these avant-garde styles!!”

Luis felt a little embarrassed hearing this. Usually, they fastened from the back. He had heard of front clasps, but what on earth was this magic clasp???

”It is indeed a bit hot. I will take it off myself. Do not break it for me. It is quite expensive.”

Nancy broke free from Luisʼs embrace and sat up a little awkwardly, putting her hand into her nightgown. This unintentional lift revealed her panties, which were black lace and sheer style, very sexy.

Through the small gap, what he saw was a patch of pure white, making Luis excitedly think that she was probably a beautiful little white tiger, just like his mother-in-law.

”Ding... Sister-in-lawʼs genetic testing is complete. Hormone adjustment beginning.”

According to the information revealed by the System, the sister-in-lawʼs hysterical and unstable emotions were because she was本身接近 super female syndrome, but the strange thing was that her female hormone levels were particularly low.

The endocrine disorder caused her not only to be infertile but also traditionally sexually frigid. That night when she could not control her masturbation was entirely due to psychological stimulation triggering physical sensation.

When Luis grabbed her breast, the scent information from contact with Luis began to adjust, and she started to feel something during physical contact.

The cool and enchanting older sister, the sister-in-law, was sexually frigid. Luis had not expected the truth to be like this. No wonder her temper was always so bad.

While Luis was momentarily dazed, Nancy had already taken off her black, ultra thin bra.

She was about to put it aside when Luis snatched it away and sniffed it. It still carried her body temperature and emitted a bewitching scent that made evil desires run wild.

”Pervert, it is all sweat smell!”

Nancyʼs face reddened. She lay down on her side, turning her back to Luis, and continued fiddling with her phone.

”It smells really good.”

Luis reluctantly put the bra aside. He could faintly hear his sister-in-lawʼs disordered breathing and knew in his heart that the System had begun adjusting her genes.

Before, when a lone man and a lone woman were together, she only felt alert and panicked, without any sense of ambiguity. But now, with the adjustments, she was also showing the reactions a normal woman should have.

Excitement, sensitivity, and even the thrill of impropriety caused by the tension in their relationship.

Luis hugged her from behind. They shared the same pillow. His hands naturally circled her waist. The feeling now was that her body temperature was much higher than before.

The softness and warmth of her mature body, accompanied by a faint, alluring scent, made Luis extremely excited. His cock jumped discontentedly, pressing against her buttocks through the thin fabric.

Big sister paid great attention to body management. She often did some aerobic exercises at home and went to the swimming pool. She also had the good habit of doing aerobics.

Unlike the young beauty Liu Siying, a professional athlete whose buttocks were as strong and powerful as a female leopardʼs, big sisterʼs buttocks were full and particularly perky, very beautiful, and very firm, one could say they were perfectly shaped.

Nancy shuddered but did not struggle. She just said in a trembling voice, ”Do not mess around!”

”I will not mess around, big sister, rest assured. But it is true that I am having a little trouble controlling myself.”

Luis urged, ”Big sister, hurry up!”

”I cannot control myself... I will use my hand to help you!”

”No, big sister, just let me rub against you for a while later!”

Luis saw her ears were red and very sexy. He could not help but lean in and lick them. This lick caused Nancy to subconsciously moan.

Her face flushed crimson, and she widened her eyes in disbelief. When had her ears become so sensitive? But when Luis licked her ears again, the feeling was like an electric shock, a numbing sensation so comfortable she could not help but tremble in her heart.

”Itchy... stop fooling around.”

Nancy bit her lower lip, her breathing rapid. Her body began to feel hot and restless, and her heartbeat quickened in an instant.

She did not know what was wrong with her, why she was so sensitive and her reactions so strong. Before this, she had no passion for so-called sex at all.

In an instant, her bones went soft. Her hand trembled, and she could not even hold her phone steady, dropping it.

Luis gasped heavily at this point and said, ”Sister, I really canʼt take it anymore. Could you use your hand on me for a while first?”

”Alright, but you mustnʼt move recklessly... you promised yourself earlier that you wouldnʼt act improperly!”

Nancy sat up, her face completely flushed.

The seductive charm on her face appeared particularly mesmerizing at this moment. Ever since he had known her, she had always been the aloof, stunningly beautiful and mature woman. Even after the intense stimulation last time, she had emerged with a face of complete calm.

Seeing such a reaction from her now, combined with her exquisitely beautiful features, it would be no exaggeration to call her a peerless, nation-toppling seductress.

”Big Sister, donʼt worry!!”

Luis panted roughly, ”If I were going to act improperly, Iʼd be raping you right now.”

”Big Sister, itʼs not like you havenʼt seen it before. Why are you so nervous?”

Nancy took a deep, trembling breath, stretched out her delicate jade-like hand, and stiffly grabbed hold of Luisʼs underwear. She pulled it down herself, removing her brother-in-lawʼs only covering.

Luis cooperated by taking off his underwear, spreading his legs openly. His painfully hard cock instantly sprang to life, throbbing with excitement.

Nancy felt dizzy, as if the world was spinning. She was deeply puzzled about what was wrong with her. Previously, she had always been utterly unmoved by sexual matters, basically having no reaction at all.

But now, just looking at her brother-in-lawʼs cock made her body feel weak and limp. Her nose twitched, catching a peculiar scent.

The aura emanating from the manʼs member didnʼt smell foul or disgusting as it had before. Now, it carried a special allure, feeling very pleasant, even stirring an impulse to taste it with her mouth.

Nancy herself was unaware that her physical issues had been corrected by the System. Furthermore, sharing the same genetic sequence as Lily, she was beginning to be influenced by the aura emanating from Luis. Consequently, her reactions were becoming more intense than those of an average woman.

Her delicate, jade-like hands trembled as they grasped Luisʼs cock and began to stroke it.

Luis let out a moan of pleasure, even uncontrollably licking his lips.

Even though the physical rhythm was the same, the sensation delivered by different hands felt completely distinct. Perhaps it was because he was too familiar with his wife, Lily. The feeling from her hands was very pleasant, but psychologically, it lacked the same thrill.

But now, the hand holding his cock belonged to his sister-in-law. Her face was full of curiosity mixed with a hint of confusion, yet she stared intently at his sexual organ.

Because her bra was off, her breasts swayed softly with every movement of her hands. Though not as stunningly voluminous as his mother-in-lawʼs, they still provided a powerfully stimulating visual impact for Luis.

”Big Sister, let me hold you. You keep going!”

Luis reached out and pulled, and his sister-in-lawʼs body fell limply into his embrace. At this moment, Nancy glanced at Luis, then shyly lowered her head. It was a rare sight to see her, usually so assertive and fierce, displaying such a feminine, submissive demeanor.

”I... Iʼll help you finish first...”

Nancy spoke while switching hands to continue stroking, though her movements were still noticeably somewhat clumsy.

”Big Sister, I donʼt want you to think Iʼm taking advantage of a vulnerable situation.”

Luis held her close, his hands moving over her body through the crumpled nightgown as he panted, ”I purely didnʼt want to see you being treated unfairly. But Big Sister, you are just too captivating. Iʼm only a man, I truly canʼt control myself.”

His words were spoken with passion, carrying a tone of genuine feeling.

A soft light flickered in Nancyʼs eyes as she said, ”I know. Even though youʼre a horribly lustful bastard, you at least treat me with respect.”
