Lust System: Harem Of Beautiful Women

Chapter 10: In Mom’s Room

Luis secretly glanced over and knew his mother-in-law was still peeking. He immediately sat up, hugged his wife, adjusted the angle to make her lie down, and spread her legs around his waist.

Their joined parts were now exposed right in front of his mother-in-law. Then he lowered his head to kiss his wife’s small mouth, held her shoulders, and thrust his hips forward, driving his hard cock deep into her pussy again and again.

”Ah~ husband... you’re fucking me so hard~!!”

In the pitch-black master bedroom, the sound of heavy breathing was chaotic yet faint. Ruth peeked through the door crack, her eyes wide open, staring unblinkingly at the scene.

Not far away on the floor, her daughter Lily’s hips were almost suspended in the air as Luis’s cock slammed into her again and again with each thrust, making Lily moan in satisfaction.

There was a telescope in the master bedroom that Arthur had brought from who-knows-where. Ruth had always disliked it and wanted to throw it away, but now it finally came in handy.

Luis had only intended for his mother-in-law to get a rough view. He would never have imagined that Ruth was using the telescope to observe every detail. The slight reflection earlier had been from the telescope’s lens.

Ruth subconsciously swallowed her saliva because she could clearly see her daughter’s pussy and Luis’s lower body were both dripping wet. Not only were his balls and asshole covered in fluids, but some had even dripped onto the floor, a clear sign of how much pleasure her daughter was experiencing.

The sound of flesh slapping against flesh was crisp and loud, accompanied by a rhythm that resembled splashing water, all at a rapid pace. Combined with her daughter’s satisfied moans echoing through the room, each sound clawed at Ruth’s heart, making her breath quicken and her body restless. She crossed her legs uneasily, realizing her panties were already soaked.

”Ah~... husband, you’re so amazing, you’re fucking me to death, so hard~...”

”You’re thrusting too deep, I can’t take it~... you’re fucking me to pieces~!!”

Encouraged by Luis and lost in the throes of lust, Lily no longer held back her moans, crying out in pleasure.

To an inexperienced ear, it might have sounded like she was in pain, but anyone who had been there knew just how good she was feeling.

Just listening to these lewd sounds reverberating through the living room made Ruth feel her blood heat up, her entire body unbearably restless.

”Husband~... I’m coming again, I’m coming again~!”

After being licked to two orgasms and fucked to two more in the missionary position, Lily felt like she was going insane. She had never imagined sex could feel this incredible.

When her second orgasm hit, Luis felt like he was about to cum, but the thought of his mother-in-law watching made him even more excited. He stopped to suppress the urge.

Originally, Luis was a sub-10-minute performer. Sometimes, if he was being blown, he’d cum in just five minutes. Only when he was drunk could he last a little longer.

Now, when he checked the time, he saw that fifteen minutes had already passed. He couldn’t help but marvel at how worth it that extra stamina point had been. With this kind of sexual stamina, if he trained a little more, he could even work as a male prostitute.

It’s over...

Seeing the two of them stop to kiss, Ruth instinctively checked the time, thinking to herself that her son-in-law wasn’t bad in this department.

But then Luis slowly pulled his cock out. The moment it slipped free, it twitched. Ruth’s first thought was, How is it still so hard after cumming?

”Husband, you haven’t cum yet~...?”

Lily moaned weakly, her words striking Ruth like a thunderbolt. How is that possible?

If it were Arthur... Ruth tried to recall their sex life from years ago. If her husband had been thrusting at that speed, he wouldn’t have lasted even two minutes. Yet her son-in-law had gone at it for nearly twenty minutes.

Then, Luis picked Lily up in a princess carry and said with a smirk, ”Wife, let’s go to Mom’s room and continue!”

”Eek, no~! What if we get caught? Let’s just go back to our room, okay?”

With her shy and timid personality, combined with her mother’s domineering presence, Lily was naturally nervous.

”It’s fine, we’ve got plenty of time. Mom’s not home, how would she find out?”

With that, Luis carried her toward the master bedroom. Ruth was startled. She never expected her usually meek son-in-law and daughter to be so bold and playful, daring to have sex in her bedroom.

Panicking, she wanted to hide. The closet might make noise, so in her flustered state, Ruth hurriedly hid behind the curtains. The distance was too short for her to think of anything else.

Even though it was her own room, she felt like a thief. She knew she shouldn’t be doing this, but the thrill of peeking was undeniable. In her panic, she couldn’t think of any excuse to interrupt them.

Click—the bedroom light turned on, bright and glaring. Luis immediately spotted his mother-in-law hiding behind the curtains because her toes were sticking out, and the fabric was still swaying slightly.

Of course, he couldn’t let his wife notice, or she’d die of embarrassment. After climbing onto the bed, he adjusted their position so Lily’s back was facing the curtains.

”Husband, it’s so hard... like iron~!”

Luis sat boldly on the bed while Lily knelt upright, taking his cock into her mouth and sucking eagerly. Her face flushed as she looked up at her husband with adoration, murmuring drunkenly, ”Husband~... how much longer are you going to fuck me~...”

”Suck it properly first. There’s more for you to enjoy later~.”

Luis grinned smugly.

Looking down at his stunningly beautiful wife kneeling and sucking his cock, her red lips wrapped around his shaft, submissive as a slave, any man would be satisfied.

Lily was already fucked into exhaustion. After sucking for a while, she was clearly tired. Luis signaled for her to turn around and said, ”Wife, I’ll take you from behind. You love this position, right~...”

As he spoke, his fingers brushed her lips, and Lily sucked on them, moaning drunkenly, ”Mhm~... like that... like a little bitch, you fuck me so deep~...”

Then she turned around on her own, raising her peach-like ass for her husband to enjoy, her face dazed with anticipation for the coming storm.

Luis stepped forward, rubbing the head of his cock against her slit, making her moan. Excited, he said, ”Wife, look at Mom’s clothes and lingerie... they’re so sexy~...”

Lily was conservative and insecure, always dressing plainly, even her underwear was dull—a tragedy compared to her mother.

Lily instinctively glanced at her mother’s open closet. The nightgowns inside were shorter than hers, the lingerie had lace and cutouts, and there were even thongs...

”Eek, why are you talking about that~... ah~!!”

Lily’s words immediately turned into moans as Luis grabbed her waist and thrust forward hard, his cock returning to its familiar territory, instantly enveloped by her tight, wet heat.

The sound of flesh slapping against flesh echoed through the bedroom again, fast and relentless. From Ruth’s angle, she could clearly see how her daughter was moaning like a bitch under her son-in-law’s thrusts.

”Next time we fuck, wear your mom’s lingerie~...”

”Eek, no~... what are you thinking~...”

”To look sexier~... it’ll make your husband even more excited~...”

”Hubby, you’re such a pervert~... do you have thoughts about Mom~...”

”Of course not, don’t talk nonsense!!!”

”I don’t believe you~... Mom’s boobs are so big, you and Brother-in-law are always sneaking looks~...”

Lily, who had always been conservative and rarely moaned beyond soft whimpers, had now completely fallen into depravity under her husband’s guidance.

The safety of their private world and the overwhelming pleasure of lust made her let go, whispering dirty talk with her husband. She never imagined her mother could hear everything.

”Stupid husband~... you must be, talking about Mom’s boobs~... you’re even harder now, ah~...”

”Ah~... perverted husband~... really~...”

Lily’s moans grew more intense because Luis, now thoroughly stimulated, suddenly reached forward to roughly grope her sensitive breasts while thrusting his cock deep into her with each powerful slam.

Every thrust buried him to the hilt, each one making Lily cry out as if in pain, now unable to form words.

”I can’t hold back anymore~...”

Finally, Luis couldn’t take it anymore. He pressed his body tightly against hers, the head of his cock swelling as it pressed against her cervix.

As his slit opened, thick, hot cum shot deep into her wonderful body.

”Ah~!!”

Already overstimulated and having lost count of her orgasms, Lily convulsed violently at the scalding sensation, nearly passing out. Her body was drenched as if she’d been pulled from water.

Luis also came hard, his vision going black as he collapsed onto her, needing a moment to recover.

Seeing his wife nearly fucked unconscious, he couldn’t help but feel smug. He picked up Lily’s limp body and carried her out of his mother-in-law’s bedroom, remembering to turn off the light before leaving.

The moment the door closed, Ruth’s legs gave out, and she slumped to the floor.

”That little beast, who knew he was so strong~!!”

Ruth checked the time—over half an hour, all of it high-intensity thrusting. It was practically animalistic.

Her panties were soaked... Ruth panted lightly, tossing and turning all night. Her mind was filled with images of her son-in-law’s beast-like ferocity and her daughter’s lust-drunk moans.
