Lust System: Harem Of Beautiful Women Chapter 599 Not Petty~~ Not Jealous~~

Avery let out a sudden, slightly anxious cry. "I suppose it’s too late now. Oh well, if she sees the message, so be it. She already knows my godfather is taking us out for dinner this evening."

Leah, looking quite proud and adorable as if she had outsmarted everyone, smugly added, "I blocked her already. If my mother saw us indulging like this, she would definitely lecture me until my ears fell off."

By the time they finished two bottles of red wine and consumed half the meal, both were full to the brim. They swayed slightly on their feet as they took turns visiting the restroom.

Once they emerged, Luis had already drawn the curtains and dimmed the room lights, creating an air of intimacy and hidden intentions.

Upon exiting the washroom, they felt a wave of bashfulness and reflexively collapsed onto the bed. Attempting to sound nonchalant, Leah declared, "Brother-in-law, you are taking the sofa tonight. Don't you dare disturb us."

"After all I’ve done for you, could you truly be so cold-hearted?"

Luis adopted a pitiful tone as he busied himself bringing bottled water and an ashtray to the bedside table.

Suddenly, Avery interjected, "Did you manage to message your mom?"

"Almost forgot. You already checked in with yours, right?"

"Indeed. She is perfectly fine knowing that I am with you both."

They dared not be too open about their activities. Leah had led her mother to believe she was merely staying at Avery's; given her mother’s strict nature, admitting to letting her brother-in-law treat them to such a lavish spread was out of the question.

Avery, being more straightforward, simply told her mother she was spending the night there, which Blanche accepted without issue.

A notification pinged on his phone—a message from Blanche: Are you staying with them tonight as well?

Luis admitted it plainly. He had already mentioned his plans before arriving, so there was no reason for secrecy now.

Blanche responded with a playful jab: By acting as such a significant third wheel, you might end up with nothing at all!

They had always been a nuisance to one another, especially his sister-in-law, whom Luis had been dying to spank for her constant interference.

Blanche had no concept of how deep the relationship between the scoundrel and his sister-in-law had truly become. Even if she could guess, she certainly wouldn't voice her thoughts.

Luis flashed a wicked grin and typed: I will find a way. My confidence is unshakable.

Blanche’s final message consisted of but one sentence: Make sure you use protection.

The chat was so alluring it could make any man lose his composure, especially with her own daughter nearby, radiating such a fragrant and tempting aura.

The two girls laid face down on the bed, their rounded figures appearing particularly sweet. They kicked their legs, emitting a kind of innocent charm that felt impossible to resist.

Leaning on their elbows to check their phones, the view from the front must have been spectacular.

Four perfectly round, immense breasts pressed together, creating deep cleavage visible from the open necklines of their tops—the impact was entirely overwhelming.

Luis felt his breath hitch. Unable to help himself, he crawled between them and wrapped an arm firmly around each girl.

Avery’s frame softened instantly, and she leaned into him with a coy smirk.

Conversely, his sister-in-law froze, her breathing shallow and jagged. She tensed up and pushed against his arm, whispering, "Stinky brother-in-law, let go. I told you, sleep on the sofa. No funny business."

"Don't be so cruel. Your brother-in-law has missed you."

Luis whispered warmly against her ear.

"Whatever, I don't buy it."

She hummed in defiance but ceased her struggle, merely clutching her arms to herself to guard against further approach.

"Is it not hot in here for you two?" Luis asked deliberately.

It was a swelteringly hot summer day, and while twenty-six degrees was generally comfortable, the alcohol and the thick tension had them both perspiring.

Luis himself was burning, his own desire turning into an inferno. Without needing any extra provocation, he was already physically aroused.

"It is not hot!" his sister-in-law trembled, her voice laced with nerves.

Without a word, they set aside their phones. The atmosphere had become too heavy for women their age. The man’s scorching breath carried a blatant desire to claim them. She could not bring herself to meet her brother-in-law’s gaze.

"Leah, sweetheart, your brother-in-law has been feeling so frustrated today."

Luis leaned in and planted a soft kiss on her cheek.

She did not pull back. Instead, her respiration quickened. "That isn't my concern. If… if you really need to, go book another room for yourself and Avery."

It appeared his efforts to influence her were seeing results. The little troublemaker had been jealous and intentionally intrusive, yet now, after a moment of hesitation, she was willing to cede ground.

This was substantial progress. However, for a schemer like Luis, this was only the beginning.

Luis gave a soft chuckle. "Your brother-in-law knows you are feeling upset. I have gifts for you both. Does my dear Leah want hers?"

"What is it?" Leah asked, her eyes sparkling with anticipation.

Luis leaned against her ear, trailing his tongue along her crimson lobe. "It is a surprise. As long as you don't get jealous tonight, I guarantee you will love it."

"I… I am not so petty. Why would I be jealous?" His sister-in-law huffed with feigned dignity.

"Is that true?" Luis teased, applying a bit of reverse psychology.

Despite her sweet appearance, she was known to be bullheaded and prone to overthinking.

She had a jealous streak, and given her mischievous nature, typical coaxing often failed. While she acted like a temptress with Avery, she remained stiff and awkward with him—that was the core struggle.

Reverse psychology, therefore, was the superior tactic. Especially since they were intoxicated, he had to strike while the feeling was right.

"Ridiculous!" The younger sister-in-law’s face flushed a delightful shade of crimson. She shot him a flirtatious glare and added, "Even if you two act like dogs in heat, I will not stand in your way, alright?"
