Lust System: Harem Of Beautiful Women

Chapter 165: What Do You... Want To Do?

”So, because I feel for you, Big Sister wants to help you ejaculate, to spare you from such discomfort.”

Luis was already losing control at this point. His hand slid up her pale, smooth thigh. The touch sent a shiver through Nancy, but she didnʼt pull away. Clearly, a hint of desire was now visible in her eyes.

”Big Sister, we share so many secrets between us now.”

Luis swallowed hard with pleasure, panting, ”To be honest, if you werenʼt my sister-in-law, Iʼd really want to just spend money and keep you as my mistress.”

”You naughty boy, how old are you? Youʼre not some middle-aged man, why do you always have these kinds of thoughts?”

Unable to restrain himself any longer, Luis sat up suddenly and wrapped his arms around Nancyʼs sexy, alluring body. His eyes were red as he stared at the vision of breathtaking beauty before him.

”Big Sister, I used to have this stupid thought: itʼs such a pity that youʼre my sister-in-law. Otherwise, I would definitely pursue you.”

”And now?”

Nancyʼs eyes were hazy with desire as she panted, her body becoming pliant.

”Now I think... the fact that youʼre my sister-in-law makes it even more thrilling. Your allure is greater than anyone elseʼs...”

His vulgar words also served as a form of praise, sending a strange thrill through Nancy. Perhaps if it were any other man, she wouldnʼt feel so coy and excited.

But this was her brother-in-law... Fueled by the jealousy that had accumulated over this period, Nancy found herself more accepting of this absurd relationship and her brother-in-lawʼs teasing. She even felt a secret pride, thinking that she must be far more attractive than her sister.

Sister-in-law Nancy: Favorability Meter 75%.

”Ding... Sister-in-law mission level upgraded. The leg job mission objective remains unchanged.”

”Ding... Favorability Meter increasing rapidly. The System rewards a random Easter egg for the mission line.”

”Ding... System prompt: At 75% Favorability Meter, direct sexual intercourse is not advised.”

Luis suddenly snapped back to reality. He truly hadnʼt expected the mission parameters to change, but as he processed it, his face lit up with delight.

By now, fine beads of sweat had appeared on Nancyʼs face and nose. Her two hands alternated smoothly as they stroked him, any earlier clumsiness completely gone.

Her other hand began to gently caress his hardened testicles, her movements soft yet provocative. It seemed women indeed had a natural talent in this area.

It felt incredibly good. Seeing her earnest expression, it was clear she wanted to use this rapid stroking technique to make him climax quickly. The Systemʼs reminder was correct; even though his sister-in-lawʼs attitude was seductive now, it still wasnʼt the right time to take her fully.

”Big Sister, youʼre making me a little sore!”

Luis quickly stopped her continued stroking. It wasnʼt actually painful, but the psychological stimulation was immense. If she continued much longer, he would ejaculate.

”Ah, okay...”

Nancy stopped her movements somewhat flustered, her face flushed with a dazed expression. She complained, ”Both my hands are getting sore. How come you still havenʼt cum yet?”

”If you carry on like this, how could Lily possibly handle it...”

”Big Sister, let me touch you!”

Luis hugged her from behind, his hands moving to take off her already disheveled and wrinkled slip nightgown.

Nancy was startled and struggled, saying, ”No, no! You promised you wouldnʼt do anything improper!”

The Systemʼs judgment was indeed correct. Although the atmosphere was highly charged and the air thick with desire, it was still not the opportune moment to conquer his sister-in-law.

Luis had been mentally prepared for this. He began kissing her snow-white neck, licking it lewdly with his tongue as he whispered, ”Big Sister, if you donʼt agree, I promise I wonʼt fuck you.”

”I wonʼt take your panties off.”

”Iʼve been suffering for so long. If you donʼt let me touch you a little, without some extra stimulation, itʼs very hard for me to cum.”

Luis was naturally persistent now. He moved upwards, trying to kiss her lips, but his sister-in-law turned her head away to avoid him. Even though her body was burning with heat, she maintained her rationality, still feeling somewhat awkward about the situation.

Luis felt a twinge of regret. He should have made her drink some alcohol tonight. Alcohol, the matchmaker of lust, could have made her more excited, making things easier for him.

Although Nancy remained silent and avoided Luisʼs kisses on her lips, she didnʼt refuse when he kissed her face instead. She let out a soft gasp and released her grip on her own nightgown.

Overjoyed, Luis immediately, with her bashful cooperation, proceeded to remove her slip nightgown.

Nancy instinctively raised her hands to cover herself, but Luis would not allow it. He immediately grabbed her wrists, preventing her from shielding her chest.

A pair of full, plump breasts swayed into view. They were perfectly round, a firm C-cup, standing pert and upright. Their shape resembled two fresh, large white steamed buns, and like the rest of her body, they were pale and flawless, emanating a captivating allure.

Even though she was a married woman, she had never breastfed a child. Furthermore, Daniel was inadequate in that aspect, and her sister-in-law was sexually cold. Therefore, despite being a wife, her body retained a feeling of youthful freshness everywhere.

Her areolas were tiny, almost invisible, and her nipples were small and surprisingly a captivating shade of pink, trembling enticingly. One could easily believe these were the breasts of a virgin.

”Stop... stop looking! What exactly do you want to do?!”

Nancyʼs face was already flushed crimson.

Her thighs intertwined uneasily, full of wariness. Now, wearing only her panties and entangled with her brother-in-law, that thin, last piece of fabric offered her little sense of security.

She felt she was going mad. Why did things always escalate to such a crazed point?

Most importantly, she felt her panties were soaked through. She had never been this wet before, never produced so much fluid, and her body had never felt so intensely sensitive.

”Big sister, give me a blowjob!”

Luis whispered into her neck, licking it as he spoke.

”Donʼt talk nonsense...”

Nancyʼs face instantly turned a deeper shade of red, a mix of anger and shame. Even as a married woman, oral sex was still unfamiliar territory. Daniel had asked many times, but she found it disgusting; just a few shallow licks were all she could barely tolerate before feeling repulsed.

According to the information gathered by the omniscient System, Daniel had only managed to tempt her into oral sex once, using an LV bag as an incentive. But halfway through, she felt so nauseous she started gagging, thoroughly disappointing Daniel and causing him to go soft instantly.

In other words, her sister-in-lawʼs mouth had never been truly fucked by a cock, so Luis was naturally filled with anticipation.

However, Nancy was very resistant. For now, Luis didnʼt force the issue. His hands directly grasped her full breasts.

They were almost the same size as his current wifeʼs. The sisters even had similarly round breast shapes. They fit perfectly in his hands, allowing him to knead and fondle them wantonly. They felt incredibly firm and elastic, the sensation astonishingly good.

”You... you... just finish quickly, okay!”

Nancyʼs hand also reached down between Luisʼs legs, grabbing his hard cock and starting to stroke it again. This time, she still bit down on her silver teeth, remaining somewhat guarded, ”You can touch them, but no sucking.”

Her voice trembled as she said this, because the sensations were driving her insane.

Her brother-in-lawʼs hands, just casually kneading, sent waves of pleasure so intense that Nancyʼs spine tingled. His rough hands seemed magical; just the friction against her hardened little nipples brought a cataclysmic, mountain-shattering kind of bliss.

Impossible... Could it be she had taken an aphrodisiac?

Nancy even suspected Luis had drugged her, but she hadnʼt eaten anything all night, not even a sip of water.

But aside from that explanation, she couldnʼt fathom why her body was so sensitive. Normally, it was hard for her to get aroused; she didnʼt even have much desire for masturbation.

When she first got together with her husband, Daniel, having her breasts touched or kissed felt quite mundane, even though her husband back then was enamored with her perfect body.

He was very willing to perform oral sex on her, but the feeling of him licking her was nowhere near as impactful as her brother-in-lawʼs kisses on her neck, and certainly not as exquisitely pleasurable as the caresses to her breasts now.
