Lust System: Harem Of Beautiful Women

Chapter 222: Taboo... Sinful

Her snow-white labia were exquisitely delicate. With just a slight parting of his tongue, he invaded his Mother-in-law’s honeyed passage, skillfully finding and gently closing his lips around her pearl-like, tender clit. Mother-in-law could not suppress a sharp, involuntary cry.

After a few more licks, Luis faintly sensed something was off, but he could not quite pinpoint what it was.

With his prior experience, Luis knew this was an extremely sensitive spot for her. Though it had been slightly dry moments before, now with just a few teasing flicks of his tongue, he felt her pussy begin to twitch and quiver, followed by a surge of scorching, slick arousal flowing out like a steady stream.

”Mom, you’re still so wet!”

”Just a few licks and you can’t take it... The panties you wore tonight aren’t nearly slutty enough, the ones from last time were much better.”

After a few more licks, Luis discovered his Mother-in-law was already completely drenched. Overwhelmed with excitement, he stroked his rigid cock a few times, climbed onto the bed, spread her legs wide into an M-shape, fully exposing her dripping, hairless, beautiful pussy.

Kneeling between his Mother-in-law’s legs, gazing at her mature, voluptuous body, Luis thought of all the harshness, all the temptation she had subjected him to over the years.

His face was flushed crimson with arousal, his eyes gleaming with a feral light. Gripping the head of his cock, he rubbed it up and down her labia several times. Feeling her body begin to tremble uncontrollably, he knew he had found his target.

With a sudden, powerful thrust of his hips, the glans pushed through the incredibly tight entrance, sinking deep into that supremely snug, soft, and blazing warmth. The sheer pleasure made Luis’s head spin, a dull roar filling his ears.

In that moment, Luis felt consumed by lust, his blood burning, leaving no patience for a slow, savoring conquest of his Mother-in-law’s body.

Holding her full waist with both hands, he drove his rock-hard cock into her without the slightest hesitation. As Mother-in-law let out an involuntary, sharp cry, he rammed himself all the way to the hilt, the head of his penis pressing firmly against a soft, yielding spot deep within.

Just like the rest of her body, it was incredibly tight yet yielding and comfortable, wet and hot like a furnace threatening to melt him alive.

The tender, living flesh inside her vagina clenched and rippled around him. The long absence of sex made her feel exceptionally tight, a sensation rivaling even that of deflowering the young virgin, Maria.

Yet it was profoundly soft, its rhythmic contractions seeming to attempt to expel the invading intruder, creating an intensely stimulating friction against his flesh.

The hard glans felt as if it was pressing through a particularly soft, deep area.

If his guess was correct, he had reached her very core. He never imagined his Mother-in-law’s pussy would be so shallow—it was truly exquisite.

This was the very place that had nurtured his wife...

This was the place that had borne his elder and younger sisters-in-law...

This was a sanctuary, never defiled by any man other than his Father-in-law.

Luis felt his blood pressure spike, his temples throbbing, the blood coursing wildly through his veins in time with his frantic heartbeat.

His heart swelled with such turbulent emotion he nearly wept. His cock was harder than ever before, aching with an almost painful intensity.

His thick, rigid shaft pulsed deep within his Mother-in-law. Luis, breathing raggedly and eyes completely bloodshot, gripped her waist and began thrusting vigorously, his voice a raw, excited rasp:

”Mom, I’m finally fucking you...”

”You’re so tight inside, squeezing me so perfectly...”

”Feel how hard your son-in-law’s cock is...”

Her voluptuous body rocked with the force of her son-in-law’s powerful thrusts. The disheveled Mother-in-law gradually began to regain consciousness, panting heavily, emitting soft, sob-like whimpers: ”No... pull it, pull it out...”

”Mom, just relax and enjoy it. It’s too late to pull out now.”

Luis spoke excitedly as he yanked the covers completely off her. Her heavy, swaying breasts came into view, but as his hands closed over them, he immediately sensed something was wrong.

Though they were similarly large, too full for one hand, the shape of the nipples felt different. If he remembered correctly, his Mother-in-law’s nipples were perfectly round, alluring like pearls.

These in his hands were distinctly smaller, less plump.

Stunned, Luis froze. He looked up; her face was still obscured by tangled hair, but looking closer, a wave of numbness washed over him.

His Mother-in-law had dyed and permed her hair into sexy, voluminous waves. The woman beneath him had straight, standard black hair—how could he have missed such an obvious difference?

What made Luis’s heart truly clench with dread was her flushed face, her ragged breathing, the way she was shaking her head in distress as her eyes began to flutter open.

Just then, the bedroom door flew open.

Luis instinctively turned his head.

There stood his Mother-in-law, Ruth, in the doorway, staring at the couple joined together on the bed with a look of utter horror.

Ruth’s face changed instantly. She hurriedly shut the door behind her, rushed to the bedside, and whispered in a panicked voice, ”You sinful... you little bastard, you...”

She was breathless with fury, rendered almost speechless, staring helplessly as her son-in-law’s cock remained buried inside her sister’s slick pussy. Her mind reeled, blank, unsure what to do.

”Mom, you... why aren’t you in bed...”

Luis seemed to realize whom he had been fucking. His first instinct was to play dumb, his face a mask of terror as he asked, ”Who is she?”

”This is a sin! You... what did you promise me!”

Ruth stood beside Luis, watching her son-in-law’s member penetrating her sister’s body, feeling dizzy and utterly panicked.

”They were both completely drunk. Your aunt has a low tolerance; she was so dizzy by the time we got home she couldn’t even walk upstairs, so I let her sleep here.”

”Your eldest sister wasn’t much better. She went straight upstairs and threw up in the bathroom. I was tending to her, she made a mess all over me.”

”After she finally fell asleep, I fetched her some water, and I was so exhausted I just took a quick shower upstairs...”

”I came down, and you... you sinful...!”

Ruth was wearing an extremely sexy slip nightgown that barely reached her thighs, her purple panties faintly visible beneath, incredibly alluring.

The thin spaghetti straps and deep V-neck were designed for someone with a generous bust. She wore no bra, yet her deep, captivating cleavage was on full display, a dazzling expanse of pale skin that was utterly tempting.

That evening, seeing Luis’s arrangements, Ruth had already felt a restless, clawing anxiety...

The other four were staying upstairs. She was the only one in the master bedroom downstairs...

While her son-in-law was supposed to be sleeping in the living room.

Last time, under similar circumstances, she had been taken by her son-in-law. Though they hadn’t gone all the way, the shame of mutually tasting each other’s most intimate parts had nearly driven her insane.

Added to that was the memory of giving him a titfuck, the mind-shattering ecstasy of his tongue on her... Beyond the shame, Ruth often found herself fantasizing about how incredible it would feel to finally have him inside her fully.

Though she had drunk plenty tonight, she was far from drunk. Instead, a restless hesitation gnawed at her—should she take the initiative and seduce her son-in-law? Using alcohol as an excuse for losing control was the perfect cover to dismiss ethics and morality.

Even if it was self-deception, Ruth knew the two of them were destined to shatter that final taboo.

Because physically, mentally, emotionally—she felt she could no longer resist the temptation her son-in-law presented.

After her shower, Ruth had deliberately chosen this seductive nightgown. Descending the stairs, she had been wrestling with the idea of proactively seducing him.

The thought of being reckless in the living room... it was nerve-wracking yet thrilling. Under the influence of alcohol, her defenses had long since crumbled.

Her only hesitation was whether she should be the one to initiate something so intimate if her son-in-law was sleeping soundly.

The mere thought made her panties damp. Slightly intoxicated and flushed with desire, Ruth had gone downstairs, only to be struck dumb upon reaching the living room.
