Vol. 1 Chapter 4 – Confinement of Conception – Days of Coerced Pregnancy

After the hot spring trip, Nami and her younger sister, Marin, started living in the Suzuki household. Initially, Shuhei had reservations about Marin moving in but he reluctantly agreed under the condition that it would be temporary until she graduated from college.

“Alright, I’m off.”

“Take care. Did you forget anything?”

“No, I’m good. Say hi to Dad for me.”

“Oioi, don’t treat me like an old man…”

Dressed in a suit, Shuhei was seen off by Nami and Shuei at the front door. It had become their morning routine. With a firm thud, the door closed and after a while, Marin came down from her room upstairs.

“Fumu, have you two not become pregnant?”

“Yes. Unfortunately… am I right, Onee-sama..”

“That’s right. We’re taking contraceptive pills as prescribed.”

“But don’t take anything too strong. We don’t want Shuhei to get suspicious.”

“Rest assured, Master….”

Both Nami and Mrin said simultaneously.

‘To think I could have both of them as pets.’

Not only Nami but also Marin had become like carnal slaves. At first, he suspected it was an act but after carefully observing their gestures and attitudes, he realised it wasn’t a bluff and Yosuke’s lust burned even hotter.

“Where should we do it today…”

Despite being a modest single family home, the surroundings were field and there were no houses nearby. The fact it wasn’t a residential area helped with their debauchery.

“Let’s do it in the living room…”

“Is that so..”

Both of them had wicked glints in their eyes.

“Nami, be careful with your attire. Shuhei might be oblivious but this is getting too erotic.”

“Shuhei-san is preoccupied with work.”

As they entered the right-mat Westerned style room, Yosuke took a seat on the sofa.

‘There’s an overwhelming amount of pheromones…’

Nami, in her ivory knitted one-piece dress and black stockings, exuded a seductive aura.

“Master, look at Marin too..”

“You’re already incredibly erotic without me looking..”

The teenage beauty in a swimsuit sat next to Yosuke and began to remove his sweatpants.

‘They’ve really transformed their bodies..’

Since their defilement during the hot spring trip, they had been engaging in intercourse every day. The sisters were completely accustomed to the frequency of sex that woun;dn’t even surprise them if they got pregnant.

“I’d like a blowjob..”

“Marin will gladly feast on Master’s cock..”

The twenty-two-year-old countess pulled on her trousers with a giggle.

“Hyaaan, Master’s cock has been in great shape since this morning.”

“If you dress like that, of course I’m going to get morning erections.”

“Then, while enjoying Nami’s butt..”

Nami leaned on the edge of the dining table in the living room, presenting her beautiful heart-shaped hips to Shuhei.

‘I can’t believe they’ve fallen this far…’

Marin wore a mischievous smile and gently placed her hand on his manhood.

“Aah, Master’s cock is so hot…”

“Marin has improved her fellatio skills…”

When Yousuke praised her, Marin relaxed her chiselled beauty. She entwined her white fingers around his shaft and grip it tightly.

‘Women are incomprehensible…’

The haughty aristocratic sisters had completely lost themselves in lust. Moreover, they had accurately learned the techniques of debauchery and Yosuke’s weaknesses.

“Master, look at Marin….”

“Nnoom, you know how to use your hand well…”

The young, baby-faced beauty chuckled and ran her fingertips along the underside of the glans. Her index finger hooked onto the glans and lifted it tightly.

‘She got a face worth cherishing….’

His desires were stirred and he struggled to restrain the overwhelming desire to push her down and fulfil his longing.

“Isn’t Nami’s buttocks also nice?”

“Her fullness had increased….”

“Mouu! Say more about how I’ve become more feminine…”

“You have a charming hip.”

As he changed his words, the thirty year old housewife blushed and frustratingly swayed her peach like buttocks. Mature richness was evenly distributed, enhancing the allure of her buttocks.

‘What a sight, the stimulation is incredible…’

Yosuke indulged in the pleasure of receiving a blowjob from Marin while savouring the sensation of Nami’s buttocks with both hands. Yosuke was intoxicated by the devastating sight that would probably shock Shuhei to death if he knew about it.

“Lick, Mmm, why is Master’s cock so big? I can’t lick it all…”

“It gets bigger when you lick it. But you prefer it thicker, right?”

“Yes..I love it..”

When the sisters’ carnal desires aligned, even their responses were perfectly synchronised.

Marin slowly stoked the shaft with her right hand and used her tongue to trail from the glans’ underside to the urethral opening. Sticky saliva clung to the flesh.

“What’s wrong, Master? It’s rare for you to stay silent.”

“When the pet becomes skilled, the owner doesn’t need to discipline as much..”

“That’s troublesome, because…”

Marin glanced at Nami briefly.

“We want a reward…”

Both of them turned their seductive eyes towards him. Whether in their slender swimsuits or voluptuous knit dresses, their bodies sirred his desires. 

‘Kuuh, I have to control myself…’

Yosuke, despite his age, couldn’t help but fantasise about an early encounter.

He pulled back his hands and took a deep breath, trying to calm his mind with his eyes closed.

However the two mature women didn’t loosen their grip.

“Nhho,ooouu….”

Involuntarily, he opened his eyes to find both Marin and Nami gripping his dick from both sides. Twenty fingers clung to the thirty-centimetre manhood. 

‘Oooh, I feel like I’m about to explode from pleasure…’

The fingers of Marin and Nami were different in thickness and movement. The subtle differences in pressure intensified the sensation, making it even more vivid.

“Are you meditating? Don’t ignore our service…Ufufu, you’re already feeling so much..it’s throbbing so much…”

“Onee-sama..let’s lick each other…”

“Guoooh…”

A masculine roar escaped from Yosuke’s mouth.

“Nami and Marin’s tongues moved around the glans in a way that seemed to gather his desires.  They varied the pressure of their tongues, sometimes pressing firmly and at times moistening with their saliva.

‘Being pleasured by both of them is irresistible…’

Moreover, they were aristocratic sisters, exceptionally beautiful. Their distinctly sharp features and luscious lips set them apart from typical Japanese women. Sedictovely, their lips and tongues with Yosuke’s arousal. 

“It’s the best, right? Ufufu, you make such lovely sounds.”

“It is, Onee-sama…Master, you’re already leaking..”

“Guh..that’s…”

Yosuke’s pre-cum began to ooze from the dark-red tip.

‘The most sensitive spot…’

Two tongues tantalising tease the glans as if beckoning for semen. Resisting to thrust his hips forward, he barely savoured the pleasure.

“Let me suck it dry, Marin.”

“Aaa, Onee-sama…”

Marin moaned longingly. Her well-formed breasts swayed temptingly. The swimsuit fabric accentuated the curves of her supple form and her nipples had grown erect.

“Nnhoou, hooo..that’s good. Your blowjob is truly amazing..”

“Now…after all this times I’ve sucked you off and taught me, it was worth it, right?”

“With a mischievous chuckle, Nami pressed her lips against the tip.

Intense pleasure surged through the hips.

‘Their provocative gazes are enticing.’

Nami and Marin didn’t divert their eyes from Yosuke. The scent of a woman became more intense and Yosuke’s groin throbbed even more. Both of them continued to lovingly suck on the old man’s shaft.

“Now, it’s Marin’s turn…”

“It’s too big to fit in my mouth..”

“But you did take it in your mouth the other day.”

“That was rather forceful…Master..”

“Uu, if it’s too much, I could ask Nami to help..”

“I didn’t say I couldn’t do it.”

Marin chuckled, her laughter free of any reservation she had shown as a countess.

‘Her oral skills have also improved…’

If Yosuke could have gotten away with not doing the deep-throating, he would have. But he could sense that Nami and Marin also wanted to indulge in the ecstasy of the subjection.

“Master going to take the offensive…?”

Marin looked up with a seductive sidelong glance.

“Oh, yes. That’s right…”

‘From here, it’s time for me to take over…’

The catalyst for the transformation of the obedient Yosuke was deepthroat.

“Nami, lick the sack.”

“Yes. I’ll give you a vacuum fellatio.”

Yosuke’s rough hands grabbed Marin’s head.

“I haven’t started yet…”

“Ah, my apologies. Even pet service has its order.”

Gently caressed, Marin began to feel a sense of fulfilment.

‘How did it come to this…’

The humiliation that shattered the pride of the noblewoman was now forgotten. The only thing her rational mind was interested in was the pleasure she could currently attain.

The Nikaido family did not oppose Marin’s relocation. Leaving the house was typically reserved for marriage, so she had been prepared for estrangement due to the scandal.

However, her current situation guaranteed a life without any hardships.

“Haaumuu,mchu…slurp…Master, it’s better to lick the underside, isn’t it? Well then…”

She once again licked up the underside of the shaft from the base and planted a kiss on the urethral opening.

“Kooouu….”

“Ufufu..such a nice sound..”

Marin pressed her plump lips against the glans. Her lips quivered as sweet saliva dripped. After taking a deep breath, she slowly slid her mouth down the throbbing length.

‘It’s still big…’

The 22 year old beauty, who was unfamiliar with men, compared it to Shuhei’s penis. Occasionally, she had glimpsed her sister  having sex with Shuhei. The tapered protuberance was entirely different.

“Uuum..Mmmumm..”

As she excitedly flared her nostrils, Yosuke’s touch changed. 

“Keep at it, Marin. Once you get used to it, it will feel really good.”

“I’m not going to do anything gruesome. Nami, don’t worry……noouoh……”

“Fumuuu…”

In a sitting position on the sofa, Yosuke couldn’t move his hips.

Naturally, Marin’s beauty was sandwiched between Yosuke’s hands with astonishing strength.

“Muju,jiyupo, fuumu, afuu……”

“Uohhh..I can’t take it. Marin’s vacuum, pressing against the oral mucosa. It’s different from the wau Nami teases with her tongue..”

Yosuke intoxicated by pleasure, wore an ecstatic expression.

The slurping of Marin’s saliva mixed with pre-ejaculate. Suddenly there was a scent of chestnut flowers. Marin obediently moved her beauty forward and backwards.

“There’s plenty of meat here…it’s so hard…”

The size of the erection was extraordinary. The hardness, heat and thickness took over consciousness, making everything hazy. As Yosuke’s penis taste spread in her mouth. She felt like losing consciousness.

“Master, are you going to climax because Marin’s deep-throating? I’ve been told that it wouldn’t be interesting to violate an unconscious Marin..”

“As expected. Nami, you remember well.”

“Recently, it seems that Marin is more to Master’s liking than Nami.”

Nami’s eyes, just inches away from Yosuke’s eyes and nose, came into view.

‘It seems like she’s feeling jealous….’

Sometimes, Nami’s comments began to show signs of jealousy. As Nami mentioned, even when the two of them served together, Yosuke would choose whether it would be Nami or Marin to have sex with first. 

“I prepared Marin and then had a good time with Nami..”

“Maaa~ In that case, Marin is the one to be pitied..”

“I don’t intend to show pity to a pet..”

“Even a pet as a flesh slave can feel jealousy. hey, it’s okay once in a while, Master…”

“W-wait, my blowjob hasn’t finished yet.”

Yosuke let go of Marin and caressed Nami’s head.

“Today, Nami is also wearing a matching swimsuit with Marin.”

“I understand…I’ll give Marin the chance..”

Yosuke’s hand was completely away from Nami’s head

“Hamu, chusu, fuumu…..”

Taking the flesh tree out of her mouth, Marin kissed the tip.

Yosuke’s sturdy hips trembled.

“Let Marin serve freely as well…”

“Aaah, that seems to be better..”

Yosuke’s expression as he looked down was covered with a sense of conquest.

‘So strong…’

She took it in her hand and tasted the tip, which was like a wiener sausage. Sensing the pulsation of the male’s blood, her uterus throbbed. Instead of discomfort, the carnal desire for sensuality raced ahead, arousing the female body.

“If you let me ejaculate in your mouth, I’ll have my way with Nami. Marin, use this for self-pleasure. Normally, it’s the toy that’s buried in Nami’s lower mouth.” 

“Yes, understood…Aaa, it’s so big…”

While savouring the flesh rod in her mouth, she touched the dildo.

“It’s just slightly smaller than my dick. I had it made to be just the right size for when we have sex, so I wouldn’t be laughed at for being inadequate.”

“So, that’s why it looks similar…”

With a slurping sound of saliva, Yosuke’s face contorted in pleasure.

‘This is unusual…Master is losing control…’

Suddenly, they both realised that it had been a while since they had been intimate with each other. With the voluptuous body of the older sister and the slender body of the younger sister, there was evidently a considerable desire.

“Aaah… mmm!”

“Oooou! Marin, can you take it deep?”

“Marin is being trained for it too…”

Nami said with a hint of jealousy.

“I want to feel Master’s cock all the way in my throat..”

The meat pole wasn’t narrowing towards the base, instead, it’s maintaining its thickness. Marin felt that it was unusual to encounter such a substantial meat shaft. 

With a gulp of air, she positioned the tip at the back of her throat.

Gradually, she guided the thick flesh rod deep into her throat. The mucous membranes entwined obscenely with Yosuke’s throbbing dick, mixing body fluids and saliva into one.

‘Aaah, Master’s cock, it’s about to…’

Unsually, Yosuke’s climax came quickly.

“You used a hidden technique…nnoo,hooouuu..!!”

With a loud roar, Yosuke grabbed Marin’s head and lifted it up.

“Noo, don’t grab me…..”

“Let’s get this over with in one fell swoop.”

Yosuke seemed to have already reached the end of his patience.

“You’re excited aren’t you…..I am too….”

“That’s a good thing. Nami also wants to be penetrated by Master’s healthy dick.”

“I see..Marin, are you okay?”

Marin nodded vigorously.

Yosuke’s hand repeatedly stroked Marin’s short bobbed hair.

“Nami looks rare in a swimsuit..Ooi..I’m about to…”

Even though they were having unrelated conversations, it seemed like their sexial desire couldn’t be suppressed.

‘Aaah, it’s swelling…here it comes!’

The glans swelled inside her mouth with a gushing sound. Shortly after, Marin’s eyes widened. Along with the intense scent of chestnut blossoms, a viscous white fluid covered her throat mucosa.

Yosuke’s throbbing member danced with joy inside her mouth with Byubyu sound.

‘The amount of semen is incredible…’

It was safe to say that it was the largest ejaculation she had ever experienced. Marin wriggled her body in her tight swimsuit, desperately swallowing Yosuke’s seed deep into her throat. Her eyebrows were furrowed and tears welled up at the corners of her eyes, conveying an indescribable feeling.

‘I see, I’ve never seen Onee-sama have sex…’

It was either Marin or Nami who would be with Yosuke, or occasionally both of them. In either case, Marin would be considerate of Nami’s needs and she had never witnessed Nami’s unravelling from beginning to end. 

“That was a great fellatio. Marin, take a little break.”

Yosuke withdrew his meat rod from Marin’s mouth.

Thick semen leaked from the beautiful woman’s mouth. Marin, in a trance-like state lay on her back on the living room table.

“Yes it was, I’ve been watching Nami’s blowjob..”

“Onee-sama, please…”

Blushing, Nami pulled the fabric of her swimsuit. 

“Eeeeeeh!!?”

Marin was surprised and opened her mouth.

From the edge of her swimsuit, Nami pulled the fabric into her cleavage. The fabric tugged between her cleavage, making her 95-sized bust even larger and enhancing its voluptuousness. 

“Please watch Nami and Master having sex…”

“Onee-sama…”

Nami got down on all fours on the living room table, with underneath her.

“You don’t need foreplay…”

“Nami always has a vibrator ready in her uterus”

“Aa-ah I see…”

Yosuke grinned.

‘Come to think of it…’

As a condition of becoming a female pet, she had been told to prepare herself to accept Yosuke’s penis. Apparently, Nami always has a vibrator ready. In case Yosuke asks for it at any time.

“Let’s see…”

Yosuke reached out to Nami’s peachy buttocks as she raised herself in a doggy style position. Plunging his fingers from the side of her almost bursting hips deep inside, the thirty year old married woman closed her eyes tightly.

“Nnah, Master..your fingers are so thick…”

“You’ve really become a wanton pet. Are you close to cuming just from my fingers?”

“This is terrible, I used to be a chaste housewife….”

“Shuhei doesn’t notice the change in his naughty unfaithful wife, that is a problem too. Oh, there it is.”

It seemed like he was extending his fingers deep into her seductive flesh. After the scent of her arousal reached his nostrils. A low-frequency sound vibrated his eardrums. 

‘Is she always using a vibrator!?’

Marin hadn’t been ordered to keep one at the ready.

So,unexpectedly, Yosuke began to suggest something.

“That’s right. Nami is more likely to get pregnant. It’s about time we implant this vibrator in Marin as well.”

“What do you mean? Is this your command, Master?”

“Aah, yes. The problem with Nami is that if she gets pregnant, it becomes difficult to find opportunities to have sex. Shuhei would get suspicious and if there were any strange activities,he would doubt it.”

“Please explain the relationship between Onee-sama’s pregnancy and the vibrator..”

The 22 year old beauty’s voice trembled.

“If there’s no one left to play the role of getting pregnant, then it’s inevitable that only Marin would become my pet.”

Although he said it casually, it was still a harsh declaration.

The pink, round toy was removed from Nami’s vagina. It was vibrating pleasantly. It seemed eerie, as if it were searching for another host.

“Don’t make that face…going straight for the G-spot is impossible.”

“In that case…Aaah!!”

With a gentle pull on the fabric covering her intimate area, she was made to wear the slimy vibrator. 

‘Could it be..on my clitoris…’

A shiver ran through her, in response to the tantalising heat. Right after, Yosuke reached for the switch in his hand and adjusted it. The highest intensity frequency pierced through Marin’n erogenous zone. 

“So, which hole do you prefer?”

“That is already decided….”

With a shivering gaze, Nami turned to Yosuke. Her voluptuous, bell-shaped breasts drew a smooth line, glistening. 

“A married woman’s swimsuit is quite alluring. Alright..”

“Yes. With the cum that Marin sucked off from Master’s dick, please penetrate Nami’s vagina…Mess it up…”

Nami’s voice was dripping with sensuality.

‘Aaah, being stimulated on the clitoris..’

As an artificial object stimulated her clitoris, Marin let out sweet moans. She wasn’t in a situation where Yosuke was giving her a handjob or oral pleasure.

The weight of the fact that she had fallen completely bore down on Marin’s heart. 

“Marin, I’m sorry…I’ve dragged you into this..”

Nami muttered softly.

“Don’t apologise-mouu. I can’t help but feel sad…this was our destiny..”

“Don’t talk so much. You’re my pet. Be quiet.”

“I’m sorry, Master…Aaah…!!”

Nami’s voluptuous hips gleamed as they were spanked by Yosuke’s impure hand.

‘This should be fine now…’ 

While living as a flesh slave in Shuhei’s house. Nami had been thinking about how to save Marin alone.

Marin will become the pet when it’s Nami’s time to get pregnant. She wanted Yosuke to modify his perception of both of them as flesh slaves. 

However, Yosuke made an announcement that far exceeded Nami’s imagination. 

“Nami not getting pregnant is due to the overdose of birth control pills, right? Ovulation suppressants aren’t good for the body. Recently, I’ve switched those pills to ovulation-inducing pills.”

“What!? Aaah..so that’s why I feel feverish…”

“Well, it’s not exactly an aphrodisiac but it seems to have similar effects.”

Nami’s world went pitch black.

‘Then I might get pregnant..’

She didn’t want to get pregnant with Yosuke’s child. Not as a noblewoman but as a woman, she wished to conceive the child of a man she loved.

“It seems like you’re still having strange dreams, so I need to break you into pieces. 

Yosuke’s grip on her waist tightened. 

“Master…is what you just said true?”

“Why would I lie? Sorry, even if I have to be stubborn about it. I’ll make you pregnant. It’s related to the pride of my reproductive capability…”

“It doesn’t matter… Aaah…”

A lascivious heat spread between her buttocks.

‘Then, today is a risky day…’

She had mistakenly thought she could endure it with ovulation suppressants until Yosuke got tired of it. However, it seemed that her partner wanted a child by any means necessary.

“Fuuh, nnng…”

“Kukuku, thanks to the ovulation-inducing drugs, your sensitivity is good, right?”

“Master… Do you really want a baby that badly?”

“No, I want Nami and Marin’s hearts. Nami and Marin’s hearts still belong to Shuhei.”

“How can you be so sure?”

“If you’ve truly moved on, you’d be willing to say goodbye to Shuhei while having sex, right? Not being able to engage in such shameful behaviour isn’t so much about courage as it is about consideration for Shuhei.”

Yosuke’s words, with a seemingly unknowing expression, accurately hit the emotional state of the two.

‘What a complex person…’

Slowly, Yosuke pressed his erect manhood into the cleft of Nami’s peachy buttocks.

“Master, aren’t you worried about Shuhei noticing?”

“I can’t wait to see what he’ll do. Unless you become obedient as a pet, it’s not worth it.”

“No…Aaah…it’s thick…”

Nami moaned with an agonised expression.

“Onee-sama…”

“You don’t have to worry about anything..Guuh..aahnn..”

The glans pierced the fabric hat concealed the ripe flower.

‘I still want Master’s penis…’

Since their return from the hot spring trip, sex with Shuhei had been somewhat unsatisfying. The lovemaking conveyed affection but there was a sense of distance in the lack of passion and intensity.

“Haaah…I want it..”

“Kukuku, a partially fallen flesh slave, is a pitiful sight. The body has completely surrendered, but the pet’s mind hasn’t…”

“Noo..aahh..nnffuuu..”

The competitive swimsuit ordered specifically for Marin was so tight around the bust and hips that it made her feel as if she were bound with coarse ropes. Moreover, the fabric in her crotch was uncomfortably thin. 

“It has the thickness to assume a virgin membrane. I do have a thing for rubber, after all.”

“No, aaahh..It feels like it’s about to tear..”

The hard flesh spear surged into the ripe flesh cleft.

‘It’s going deep inside my private place…’

The fabric tightly pressed against her cleft, setting into the groove. There, Yosuke’s penis pushed forcefully. Obscene sounds emerged and Nami’s fair skin turned cherry pink.

“If I turn your entire body into an erogenous zone, you’ll only think about climaxing. There’s still time. I’ll train you thoroughly.”

“Fuuaaaa….My buttocks feel hot…”

“If you want it torn, just say so anytime..”

“Yaaa…I want it right now..Noooahhh..!!”

“You want it but you don’t want to get pregnant. You lack the resolve. With a little awakening to pleasure, you could overcome it…”

“Aaauh!! Unnn..”

Yosuke’s dick penetrated with tremendous force.

‘It’s slowly tearing apart…’

Even with the sturdy fabric of the swimsuit, Yosuke’s aggressive penis caused cracks that gradually tore apart. Everytime she was violated, a layer of her reason was stripped away, awakening her female instincts.

It felt as if she was shedding unnecessary restraints.

‘It feels so good…Aah, it’s unbearable…’

The time for confession to her husband, Shuhei, had become almost nonexistent. However, while engaging with both Shuhei and Yosuke alternately, she still wanted to keep the memory of her husband’s manhood inside her.

‘Yes, it enters from here. This part is still the same…’

Nami didn’t want to forget Shuhei’s penis.

“It’s getting all slippery. A few more thrusts and I’ll hit the bullseye.”

“Aaaa, Hiiii…”

Yosuke’s flesh pillar buried itself in Nami’s peachy buttocks. The rod, wet with white nectar, with its short but impactful strokes, closed in on the mature vagina of the 30 year old.

‘My abdomen feels hot and aches…’

Hearing about the ovulation drug, Nami’s vagina unavoidably became heated. To escape  the risk of getting pregnant, she had no choice but to have Marin act as her substitute.

However, in the end, both of them would be violated.

“Fuuu…now I’m going..!”

With a strong, resounding impact, her twin bosoms swayed. 

“Aaah,Aaaahhh!!”

The wide glans of the flesh umbrella tore through the ripe flesh flower. Nami raised her pale chin, arching her back sharply. 

“You’ve almost developed your erogenous zones completely. The vaginal entrance and folds are flawless.”

“Aah, It feels good when your penis hits..”

“Nami’s sweet spot and Marin’s charm point are subtly different.”

As if inspecting the weak points of the sisters, Yosuke thrusts his flesh cannon.

‘The devil’s penis…’

Nami, with sweet sweat trickling down her forehead, clenches her molars.

Yosuke’s thrusts had an unfamiliar quality. While he was ready to vary the rhythm to arouse a woman’s senses, gradually, he lost track of the length of the flesh rod.

‘I wonder how long Master’s penis is….’

The spring of pleasure resided in the G-spot and deep within the vagina. Due to the unexpected teasing, her sanity was burnt by the intense carnal bliss.

“Kuku, you’re hotter than usual and your tightness is perfect.”

“Yaaaa,Aaaah,nnnaaah….”

“Are you excited or do you want to extract my semen from my dick?”

“It’s embarrassing…don’t make me say that…”

No matter how many times they have sex, the sense of shame remains.

‘I thought he would set the tempo with Marin…’

She had interpreted it as using her sister’s body to establish a rhythm of desire and torment Nami’s vagina. Their virile father-in-law seemed unconcerned about the frequency of ejaculation.

“Nami seems not to understand the important thing, so I’ll teach you. It’s crucial for a female pet.”

“What is it? Ah, haa…”

“When you have sex with Shuhei, the position of your uterus doesn’t change… Your dull pussy is to my liking.”

Pointed out, Nami was taken aback.

‘So that’s why Master’s penis is unusually long…’

As her vagina was thrust forcefully, Nami’s mind went blank. The only thing she could see as the fog lifted was Yosuke’s massive penis. Her brain cells were constantly filled with her father-in-law’s manhood, with no time for conscious thought.

“Now that you understand, pull your pussy back a bit. In the meantime, I’ll violate Marin.”

“Eeh..Master..”

“eeh..Onee-sama…Aahhh,Hiiii”

With confusion in Marin’s loins, Yosuke aimed careful.

“Wait, please. Don’t pull out halfway…”

As the thick shaft was pulled out with a wet sound. Nami moaned sensually. 

‘I can’t do that….’

It’s not possible to adjust the position of the vagina in a matter of minutes. This was a matter of the range determined by the female instinct. 

“Aaa, a dildo…?”

“Kukuku, this dildo is the same length as my dick..”

The pseudo-phallus, clamped by the tension of the swimsuit, was pulled out.

‘Aaah…they were comparing vaginal quality……’

Marin marvelled at the devil’s aesthetic sense. Perhaps Yosuke was jealous of Nami’s instincts, unable to be corrected even by a dildo.

“I wonder how your pussy compares. If it’s better than Nami’s, I might change the order in which I violate you… Hey, Nami, shove this dildo in!”

“Fuuua, Master… Aaahhh…”

Yosuke pushed the dildo into Nami’s rear entrance. With lewd undulations, the wrinkled opening swallowed the pseudo-phallus.

‘I have no idea about the position of my uterus…’

She was always pushed by the overwhelming presence and fulfilment of Yosuke.

“Hehehe, it’s going to be fun after shoving it in…”

“Yyyaann… Aaahh…”

With her luscious flesh undulating, Marin twisted her hips. The fabric of the swimsuit had already been loosened and the beauty had removed the swimsuit from her shoulder.

“Uhh, nnnoh..”

Yosuke positioned his penis at the dainty flesh entrance and slowly advanced his hips.

“HhaaaaーーNnn…”

With a shudder, Marin’s slender body twitch.

“Uuumu,fmuu..it seemes like my dick is going in easily.”

“Aaah, Master..It’s painful..”

“I’m going deep all at once, so breath in short breaths..”

He brushed through the fine folds and the thick flesh pile penetrated Marin’s core.

‘How far will it go…’

Honestly, the dildo from earlier was too long and it didnt go all the way in. Marin didn’t expect to get the same result as Nami. 

However, Yosuke’s reaction was different.

“Hoooou, this…Marin’s pussy is superior. It’s taken all of my dick. A top-tier female pet.”

“No! There must be some mistake..Aaah…”

Nami’s peachy buttocks made a Paaan! slapping sound.

“Don’t bark such dull things. A second-rate female pet pretending to be first-rate.”

“Aaaah,Oohh…Master…”

The head of his member touched her uterus, causing Marin’s soft skin to ripple repeatedly.

“Fumu, it’s getting even tighter..the folds are becoming more complex..”

Yosuke’s satisfied chuckle shook the hearts of the sisters.

“Master’s dick…Aaah…!”

“Hou? You can even tell when I’m going to ejacualate..Truly, you’re top-tier..”

“That…I don’t think it’s relevant…Aaah…”

“Well, it doesn’t really matter. For now, let’s have each of you ejaculate..”

The sisters cried out in a soprano voice that was a mixture of scream and moans.

In the next moment, Yosuke’s massive cannon relaesed several spurts of milky spurts of milky fluid into Marin’s depths. After finding the right moment, his flesh rod was pulled out and thrust into Nami’s mature chamber.

“Aaah,Oooh…it’s hot..Marin..I’m..I’m..cumming!!”

“Oohh, Nami…too…I’m cumming with Master’s dick..Aahh.. I’m cumming!!”

“Hahaha, let both of you get pregnant!”

With hearty laughter, Yosuke continued to thrust into Nami’s vagina with his still erect dick. 

(Finished)
