Lust System: Harem Of Beautiful Women-Chapter 631 It Feels So Good…Just Kill Me Already…

Luis immediately let his imagination run wild. The fairy‑like sister‑in‑law playfully jabbed him as if jealous, her face flushing as she said, "You're really thinking about doing it, aren't you? Aren't you afraid of dying from exhaustion?"

"The way I most want to die in this life is on top of you."

Luis also held her close, sharing a lingering kiss goodbye, and couldn't help but ask, "Are you coming back for dinner tonight?"

"I don't know!"

"You have to come back for dinner."

"Fine, fine, I promise you, okay? You're so clingy."

Though her words were full of playful reproach, Nancy felt incredibly happy inside. Having finally confirmed her relationship with her brother‑in‑law, she was in the throes of passionate affection, thoroughly enjoying how much he thought about her and desired her.

The fairy‑like sister‑in‑law's main mission—three internal ejaculations within twenty‑four hours—meant Luis had to calculate the time carefully.

He had to use the traditional position to ejaculate inside her one more time before ten o'clock that night.

Originally, he had planned to complete the mission involving his mother‑in‑law and her sister, but by a twist of fate, he had advanced his sister‑in‑law's main mission. So he decided to push through and finish it first.

Opening the system interface, he saw his stamina value had dropped to 8.4.

It seemed that constant indulgence was taking a toll, but luckily he still had one attribute point in reserve.

"Ding… The system has upgraded the stamina module!"

"Ding… As long as the stamina value doesn't reach the peak of ten, there will be no genetic mutation. It will remain in a normal state, closer to the limits of a human being."

With a prompt like that, what else was there to say?

"Use the last stamina point!!"

With a ding, his stamina value instantly became 9.6…

Luis felt as if his whole body was splitting apart. The pain lasted only an instant, and then he became full of life again, feeling as energetic as if he had taken a stimulant.

There was a prickling, aching sensation all over his body, but instead of discomfort, it actually felt a little pleasant.

He went to his mother‑in‑law's bedroom, took off his clothes, and looked at his body. It felt almost like science fiction.

At a glance, the change wasn't huge—it was still the muscular physique the system had sculpted—but looking more closely, there were differences.

His muscles hadn't visibly swelled, but their shape had become more aesthetically pleasing, the lines clearer, exuding strength and masculinity.

Where he once had six clearly defined abdominal muscles, he now had a perfect set of eight.

His figure was tall yet lean, the kind that barely showed any muscle under clothes, but his shoulders had broadened slightly.

Everything looked exceptionally well‑proportioned, with no single part appearing exaggerated—just a full sense of linear beauty.

Unlike the exaggerated physique built with protein powder, this kind of athletic, well‑defined form looked like the result of natural training.

After pushing his stamina to 9.6, he felt a stomach cramp and couldn't help but go to the bathroom.

It was an utterly satisfying release that left him feeling completely drained, so hungry he could barely walk.

"Braised beef noodles, plus a side of cold beef slices, and an extra portion of braised beef brisket…"

He devoured the food in a whirlwind. After eating, he felt revitalized—not only was his back no longer sore, but his energy was surging, and he desperately needed an outlet to vent it all.

At the property management office, lunchtime was when everyone ate. The manager's office door was tightly locked, but if anyone got close, they might hear some blush‑inducing sounds.

Minda, dressed in a professional suit, had her hair disheveled. Her face was flushed with satisfaction, exuding an alluring charm.

Her white shirt was unbuttoned, her full breasts marked with the rough, biting traces of a man's passion. For a woman of her age, that slight roughness was an intense, thrilling kind of pleasure.

Her pencil skirt was rolled up, and the sexy stockings on her long, slender legs had been torn.

Her soaked underwear had been tossed carelessly aside. Now, after two intense climaxes, she was completely satisfied, lying limp and weak, sprawled on the sofa.

In her mouth was the member that had just been inside her. She bobbed her head vaguely, her expression one of utter intoxication.

Perhaps it was just his imagination, but after raising his stamina to 9.6, Luis felt that the shape of his penis had changed slightly.

The glans had gone from being round like an egg to more angular, like a snake's head, with more prominent veins.

From the way Minda reacted, she seemed to enjoy it more—her climaxes came faster than before. So there really had been some change.

"Hey, Winslet!"

Luis received a call from Winslet, his mentor's wife. Her voice was as crisp and lovely as ever: "Little Luis, where are you? Have you been thinking about me?"

"Every single day. So, have you arrived?"

"I'm printing some documents right now. I'll be there in half an hour."

"Okay, I'll wait for you at the property management office."

After hanging up, Luis gave a wicked smile and pulled Minda up, making her lean over the desk and stick out her round, beautiful buttocks.

He caressed her soft flesh, gripped her slender waist, and guided his hard shaft back to the familiar spot. 𝓯𝓻𝓮𝙚𝙬𝓮𝙗𝒏𝙤𝒗𝙚𝙡.𝒄𝒐𝓶

Thrusting deep in one go, he drew an uncontrollable moan from Minda:

"Oh god… so hard…"

"You little monster… don't fuck me so hard…"

"You'll swell up my pussy again… it feels so good…"

"Just kill me already…"

Her passionate cries were utterly lewd, and having sex with this uninhibited woman without restraint was incredibly satisfying for Luis.

He didn't need to be gentle—he treated her like a vessel for his desire, slamming into her with each thrust, making her mature, sexy body flush completely pink with lust.

They switched positions for over ten minutes. By her fifth climax, Minda was nearly losing her mind.

Then Luis couldn't hold back any longer. He pulled out, grabbed her head, and thrust his hips.

He fucked her little mouth as if it were a pussy, each push nearly reaching her throat, making her whimper in muffled tones.

A few strokes later, Luis let out an animalistic, hoarse groan and erupted intensely in her sensual mouth.

Time seemed to stop for an instant, leaving only the sound of their ragged breathing.
