The Twins' Laboratory (Ilien & Idrien Ksakru) (3)
The wet, obscene sounds of flesh slapping and sucking filled the room. Schlurp… slurp… slurp… schlup…
“Khh… hah…! I-inside my womb… your cock… your cock is sucking me in… ugh… it’s going deeeep… aaaaaahhh!!”
Marei had folded Idrien’s body into a tight curve and buried his massive penis deep inside her. Every time he slammed against her cervix and then pulled back, her greedy entrance clung to him like it was trying to follow, only for him to thrust upward again, piercing her sticky cervical opening with his shaft. As if refusing to lose to the incredible tightness of her divine hole, Marei pressed down harder on Idrien’s shoulders and pounded his hips with savage force, clearly engraving who the master and who the pet was.
Thick, syrupy love juices of an almost unnaturally high viscosity poured endlessly from their joining point. Already mixed with the irresponsible loads of semen he had pumped into her earlier, the frothy mixture spilled down onto the sheets in heavy rivulets.
“M-Master… aaah… I-I’m so happy… my pussy is so happy… ugh… hnnng…!”
The very same Idrien who had once coldly forced Labella to report every detail of being violated by her own son was now screaming her pleasure at the top of her lungs for the young boy. It was as if she wanted every single act she had made Labella perform to be done to her instead.
“Oh? You like this? Idrien, I’ll make you feel even happier!”
“Th-thank… thank you so muuuuch…! Haaaaaaaahhh!!”
To an outsider, it would have looked like nothing more than two bodies desperately twisting and clinging to each other. But the two beasts, their reason long since dissolved, were simply rutting like animals in heat, grinding their genitals together with raw violence and reveling in each other’s body heat.
Completely defenseless—or rather, not caring at all how she looked—Idrien writhed her voluptuous body, tears streaming freely from her emerald eyes as she drowned in ecstasy. Of course, her body had already been thoroughly trained and broken in by the young boy dozens of times. The well-conditioned female flesh didn’t simply flinch and gasp when pierced. Little by little, it began to match his one-sided, almost breeding-like hip movements, tightening her inner walls and rolling her hips to please her master.
Schluuuuurp… schlup…! Squish! Squelch! Squish! Squish!
Every time his penis drove in, her vaginal flesh would relax for only a moment before clamping down violently the instant it kissed her cervix, squeezing as if trying to wring out every drop of white fluid from the meat rod.
“Inside… press it hard and stir me up however you want… I love it… rubbing my cervix like that… hnnng… I’m going crazy… I’m losing my miiind…!”
Even as she rocked her hips in time with his, Idrien vividly described the sensation of her master’s cock churning through the squirming flesh inside her body. Her eyes had already rolled back completely, showing only white. She could see nothing.
“Khh… Now… now, Idrien… I… I’m…!”
“Yeees…! Inside… inside my womb… fill me… fill me up with lots and lots of cum… khhh… please give me plenty…!”
Her long legs, which had been tightly folded, instinctively stretched out and locked around his waist, refusing to let him pull out and ejaculate anywhere but inside. Marei felt the rising urge to cum and the sight of this once haughty, devoted bitch completely surrendering. All the hidden lust inside him erupted.
“Khhhuuuh… It’s coming… it’s coming out…! Get pregnant, Idrien! Get knocked up!”
Spurt.
From the tip of his massively throbbing penis, thick, jelly-like white gel began to gush out in powerful jets.
“Uoooh…!”
Idrien twisted her entire body as another flood of sticky gel poured into her already cum-packed womb. She threw her head back, hands clawing desperately at the sheets behind her as she gasped and shuddered.
Gluuuursh…! Spurt…! Squuuueeeelch…!
“Nngaaaaah! Ahaaaaaah…! Uaaaaaah! U-uaaaang…!”
Even as he came, her supreme female body refused to allow any distance between them. She lifted her ass and twisted her waist, swallowing his cock even deeper.
“Haa… haa… haa…”
Matching Idrien’s movements—which clung to him even more desperately than usual—was more difficult than expected. During the act, their body heat had melted together so completely that their minds felt fused in a hazy, dreamy state, but the heavy breathing that followed was unavoidable. Still, even taking a few deep breaths was enough to send fresh waves of arousal surging through him. The slight fatigue that came after such a long, intense ejaculation vanished with each breath, replaced once again by burning carnal desire rising from his lower abdomen.
Beneath him, Idrien lay trembling violently, unable even to gasp properly. Both her hands were clenched tightly in the sheets above her head. Her slender chin was tilted toward the ceiling, leaving only the sight of her pure white throat exposed.
Squiiiish… schlup… schlurp… squelch…!
This was his third ejaculation. Yet Marei let out a small sigh, feeling that his still-raging erection and unquenched lust had barely been satisfied. In the beginning, he would simply pass out from pleasure after spending the entire night with Labella. Now, he felt that one woman alone was no longer enough.
When he finally pulled his cock out of the still-warm, tightly gripping hole, a lewd pop echoed—like a cork being pulled from a bottle—followed by a thick gush of fluid from her well-used flesh. The mouth that had been chattering nonstop before insertion was now tightly sealed, her mound clenched firmly to keep the massive load of semen trapped inside her womb. The sight was so satisfying that Marei let out a long sigh and shuddered all over.
Even though he hadn’t stimulated himself much, the sheer eroticism of the scene caused the remaining semen in his urethra to spurt out on its own—splat, splaaash, splat—splattering across Idrien’s face, her massive breasts, and her belly.
“What am I supposed to do with this…”
Looking down at Idrien sprawled limply across the bed, Marei sighed again. His cock was still rock-hard, and the desire to fill another beautiful female body was overwhelming. Lately, however, he no longer felt the need to simply ravage unconscious women. If Labella collapsed, there was Ilien. Or Idrien. At least two or more of his supreme-grade meat slaves were always waiting nearby. For this perverted little boy who had developed such a bad(?) habit, the option of fucking an unconscious body had already been completely ruled out.
Knock. Knock. Knock.
Marei flinched at the unfamiliar sound coming from the terrace window, but his face brightened the moment he recognized the familiar figure. He quickly opened the door leading to the terrace and greeted the newcomer with a bright smile.
“Ren, you came at the perfect time!”
“Yes~ To receive such a warm welcome… I’m already soaking wet.”
Ilien laughed brightly as she casually began to remove her white skirt. Beneath it, her yellow lace panties were visibly darkening with moisture.
“Seriously…! This is supposed to be my time!”
Idrien raised her voice angrily. Ilien couldn’t even meet her furious little sister’s gaze. She awkwardly looked away and scratched her innocent cheek.
She had been certain that her twin sister, who was so similar to her, couldn’t possibly satisfy their Master alone. She had calculated that after three—or at most four—rounds, Idrien would be lying on the bed in a delirious heap. Like a thieving cat, she had slipped in quietly.
To be honest, Ilien felt a little wronged. Normally, when it was her time, Idrien would barge in and share their Master’s affection. Yet now that it was her turn, her sister wanted to monopolize him completely? It was an incredibly selfish attitude, even for twins.
She didn’t feel like apologizing at all. In fact, she wanted to logically crush her sister with all the usual arguments, shut her up, and leave her speechless. On top of that, because she had been playing along with Master Marei and Lady Labella’s little act lately, she hadn’t been able to return home properly. She had spent lonely nights and mornings comforting herself with her fingers. And yet here her sister was, stealing her spot and acting like this?
“I’m only doing this much because I’m your older sister! Listen properly!”
Faced with her younger sister’s fiercely blazing green eyes, Ilien couldn’t even smile. Her lips trembled. Listen properly? She swallowed the words that had risen all the way to her throat. You stupid bitch. Thoughts she would never normally have toward her own sister poured out.
Normally, Ilien could laugh off most things with a bright smile, but being abandoned at their Master’s house lately had become far too painful for her to endure any longer.
“Seriously… just wait a little longer. I’ll give you the second spot, okay…?”
Second?
“Shut up!”
“Sister…?”
Startled by Ilien’s harsh tone, Idrien’s eyes widened. She cautiously studied her older sister’s expression.
“Do you even realize what you’re saying right now…”
Ilien’s voice trembled with gloom. You idiot. So you think you’re first place, huh? Ilien had been desperately struggling just to stay by their Master’s side, not even able to reach second place. She had pitied her sister for being treated like nothing more than a toy. And yet she casually mentioned giving her “second place”?
“Sister… did you just yell at me…?”
“Haa……”
At Idrien’s reaction, Ilien let out a long sigh. She no longer knew what to do. Fine. Let her do whatever she wanted. As blood relatives, it was indeed pitiful to watch Idrien prance around on stage without knowing anything. But with rage boiling over, Ilien decided not to care anymore. She even began to hope that Labella would completely shatter her during the time she had been sharpening her fangs for.
“This is ridiculous… ha… I’m going insane.”
Hurt by her sister’s reaction, Ilien couldn’t figure out how to express her anger or what she should do. She roughly tousled her own hair. She felt embarrassed in front of their Master, who was curled up nervously between them, watching their fight. She had always wanted to show him only her cool, superior side. It was humiliating that her older sister—family—was exposing her like this in front of the young boy.
She had wanted to remain the cool older sister, the wonderful teacher, the proud wife standing by his side. Yet the very person who had dragged her into this pleasurable hell was now interfering instead of helping. The boy who had been fucking her sister right in front of her suddenly froze, unable to move his hips in the sharp atmosphere. His thick cock remained buried deep inside Ilien as he nervously glanced back and forth between the two women.
“Y-you two… shouldn’t fight…”
Ah. I just had a good idea.
A wicked smile spread across Idrien’s lips.
“Marei. Just a moment.”
Even while angry, Idrien carefully embraced the boy’s body and slowly rose. Her touch was far too gentle and cautious to be the way one treated a cheating lover who was currently inside her older sister.
Schlup… schlurp… schlup… schlurp…!
Whether it was because the meat club was simply too large to be considered human, or because her vaginal walls desperately didn’t want to lose their Master, Idrien had to exert considerable effort to pull Marei’s body tightly against her and yank him back.
“Huh? Ah… ugh… ah…”
Being handled by a third party, Marei let out soft moans filled with strange pleasure and reluctance.
Slurp… schluuurp… schlup… slurp…
The lewd, embarrassing sounds echoed from their joining point—the petals that wriggled and clung desperately to the cock, not wanting to let go, even trying to follow it downward with powerful suction, versus the third party’s force trying to pry them apart.
“Khh… khh… hnnng… haa…!”
Ilien couldn’t hold back the climax that burst through her and cried out wildly.
“Pfft… Look at that, Sister. Your pussy is clinging so hard it’s getting dragged along.”
Idrien mocked her sister’s state as she held Marei tightly and stepped backward, forcibly separating the two of them. From Marei’s perspective, Idrien had shown the exact same clinging pussy when he pulled out of her earlier, so there wasn’t much difference. But right now, he felt that saying anything might make Idrien angry, so he deliberately ignored it.
“Hah… hah… hnng… ah… aah… hahuu…”
Only after the incredibly thick and long penis had completely left her did Ilien finally manage to breathe, panting heavily on her younger sister’s bed. With her eyes closed and breathing ragged, her enormous breasts rose and fell violently. Her pink nipples, erect to the size of a pinky fingertip, trembled visibly.
“Idrien…?”
“Let’s do something fun. Okay? Trust me and leave it to me this time too.”
The anxious black eyes looking up at her sent a tingling sensation through Idrien’s entire body. She unconsciously rubbed her thighs together and put on the gentlest expression she could manage to soothe the young boy.
“Ah, okay.”
He agreed right away when I told him to trust me.Hehe, as expected, the only one who truly trusts me is this child.
Although hurt by her sister’s shocking attitude, Idrien felt even greater joy from the boy’s obedient response. She gently stroked Marei’s cheek, then carefully grasped his penis with both hands.
“There’s something I’ve been wanting to try. And since my sister is being so rebellious… I think it’s time to educate her.”
“Educate…?”
“Hehe, yes. Education. We’re going to educate her thoroughly with this huge cock. Unfortunately, I don’t have anything as magnificent as our Master’s. So Master will fuck my sister senseless in my place. How does that sound?”
Since this was something they did often, Marei nodded obediently. He had been slightly excited when Idrien asked him to trust her, but now that it turned out to be nothing special, he felt a little disappointed.
“Alright then, shall we begin right away?”
Idrien wrapped one arm around Marei’s waist while holding his cock with the other, approaching her older sister.
“Huh…?”
“I’ll show you what it means to be ravished, so just follow along.”
Idrien gave a wicked smile, pressed the young boy’s penis against her sister’s soaked entrance, and thrust her body forward with all her strength.
Sluuuuuuuuuuuuurp…!!
The cock drove into the hole that had been trained every single day, though its usage frequency had slightly decreased lately. Immediately after, the hard yet strangely soft sensation of a cervix greeted him.
“Kuh… kuh… khurk…”
A beat later, Ilien let out a rough gasp and began to shake violently all over.
