Shinmai Maou no Keiyakusha Vol 6 Chapter 1

The Girls' Risqué Racing Swimsuits

—I can no longer continue with this deceit.

Because I really do not want – these intentions of mine, to become lies.

Part 1

After Mio and Maria, it was currently a certain day after Yuki who had also began to live in the Toujou Residence.

“—right right, Basara-san. Have you already prepared your school’s swimming gear?”

While resting in the living room after dinner, Toujou Basara was asked this by Maria.

“No, it’s not… Speaking of which, the swimming cla.s.ses will be starting next week, right?”

Basara had transferred over to this school for the second semester after the summer vacation, and now is currently in the middle of the semester. In the normal schools, there wouldn’t be any swimming cla.s.s from around this time period until next year’s summer.

--However, Basara and the others are now studying in Hijirigasaka Academy, which has got an indoor heated swimming pool.

Thus swimming cla.s.ses would be held all year round, without following the seasons.

Although Basara had already purchased his sports attire and sports shoes, it was only his swimming attire that was left out all these while. Reason being that no matter who it was, everyone had to change into swimming gear if one wanted to enter the water, which meant that majority of his skin had to be revealed.

--And after all, Toujou Basara’s whole body, was covered in countless number of scars left behind from a certain experience in the past.

When a normal person sees those scars, it would usually make them feel uneasy.

“…What to do…?”

Basara had been worrying his mind over that. It was just then, Mio who seemed to have finished helping Maria to tidy up after dinner, also came into the living room, and beside Basara – she sat down on the armrest of the sofa.

“Basara, you can’t be planning on skipping out on swimming cla.s.s, right?”

“It’s not that… but I might be considering that though.”

These scars were carved onto his body when he had committed that inerasable sin in the past, so Basara had to carry it for life. To this day, he is still gripping tightly onto his remorse for the past, really hoping that no one would see these scars.

…Additionally

Basara who hoped for the comfort of a peaceful school life, does not wish attract too much attention to himself. Just the event of being hugged by Yuki during his self-introduction, as well as Mio disclosing the information of them living together, already caused him to have only Takigawa as his only male friend in school whom he could speak with normally. During physical education cla.s.s, Basara could still hide within a corner of the changing room to not let anyone see his scars, but that was no longer possible during swimming cla.s.ses.

Moreover, Basara could no longer join any clubs or after-school activities.

So if he were to start making any friends, he could only start from his cla.s.smates.

Hence, if he were to reveal his scars during his physical education cla.s.ses, it might very well just plummet his relation with his male cla.s.smates to the lowest levels of disparity.

…Despite how dad managed to make so many friends…

Just what was it that had caused such a great difference?

“…Say…”

Just as Basara sighed in hopelessness, Mio suddenly asked in a low voice.

“Could it be… because of me?”

“Don’t worry, it’s not because of you—…”

Basara raised his head, and saw a light colour appearing on Mio’s neck.

That, is the marking of the collar that signalled the activation of the curse of the Master-Servant Contract. Mio was probably worried that she had caused Basara some trouble to not let him attend the swimming cla.s.ses, which caused feelings of guilt resulting from regret over it. Basara hurriedly grabbed her hand and held it warmly, and said:

“Really, it’s really not your fault… The problem lies completely with me.”

“…Really?”

“Really.” Basara answered the uneasy Mio while nodding.

As of right now, the Current Demon Lord Faction are still after Mio’s power, so it is a given that Basara needed to stay under their radar; and it was not just the current Demon lord, the enemy who had killed Mio’s adoptive parents – the high-cla.s.s Demon Zolgear was also after Mio, and had sent out s trusted aide of his that was even stronger than Takigawa in terms of battle power.

Hence, once he attracted the attention of those around him, he will have to further increase his awareness to see if there are any lurking enemies waiting for an opportunity. That will increase the stress on him daily, it cause him to not be able to use his full power if a battle occurs, and there was no other way around it; so Mio being worried for him over such a thing, wouldn’t help the situation at all.

“Hey… don’t put on such a gloomy face.”

“Ah——…”

Basara pulled Mio’s hands, and hugged her.

Mio seemed to not have expected that, and followed his pulling into his arms. While within Basara’s warm arms, those large b.r.e.a.s.t.s of hers were tightly pressing onto Basara’s body.

…C-Calm down…

This was for Mio’s good. Despite how Mio’s sweet body scent and her extremely soft body threw his heartbeat into disarray, Basara still feigned calmness, wrapping his hands around Mio’s waist.

And attempting to display Jin’s mature calmness in his own way, he said to Mio who was closely sticking to him:

“Or else I will have to subjugate you again… Would you rather have that?”

“————！”

Mio’s body trembled, her whole face turning red.

…Great, that went well…!

Whenever he made her angry, her feelings of guilt would be broken up, so that was why Basara forced such intimate activities. Once he let Mio slap him twice, everything would be good.

As for whether would Mio ran out from the living room in anger or would he have to apologise while escaping, it depended on the situation. Completely perfect… with this, there would be no need to Mio to be subjected to unnecessary humiliation—

…Eh?

While thinking that, Mio’s hand was never raised up into the air, as he was expecting.

“ ? Umm… Mio?”

“………”

Basara asked, uneasy, to which Mio then silently stretched her hands towards Basara’s neck.

Eh, it can’t be? Not with slaps, is she going to choke me this time? Is she going to choke me to death?

s.h.i.+t, did I take it too far? Basara prepared to defend himself, but unexpectedly Mio’s hands went around his neck – directly to behind him.

And they then tightened around Basara, causing Mio’s soft body to stick even tighter onto his body.

“Eh…?”

Yet towards the dumbfounded Basara, Mio, as if having not heard that – said as if it was s.e.xy bedtime:

“……If Basara says so, it’s fine, you know?”

“ ! ————Uh… Mio?”

Eh? What? Why did it become like this? Why did she suddenly say such sweet words?

Mio’s unexpected reaction, suddenly put Basara at loss.

“A-Anyways, calm down first… alright?”

Basara grabbed Mio’s shoulders, and successfully separated their bodies; but in his nervousness he didn’t managed to grab onto his intended target completely accurately, which resulted in his hands – both his index fingers hooking under Mio’s bra straps, shocking him to hurriedly pull back his hands.

“S-Sorry…!”

But he couldn’t. After his index fingers hooked her bra straps, his actions pulled the straps to the sides, off her shoulders.

Mio’s shapely b.r.e.a.s.t.s rocked after being freed from the restraint of her bra, with their tips almost revealed before Basara’s eyes. Not only that – although their bodies are no longer in contact with each other, they are now at the most suitable distance for ‘’that’’.

「……………………」 「……………………」

Basara couldn’t help but to stare at the Mio before his eyes. In Basara’s eyes, Mio’s eyes seemed to be even glossier than just now, as if she was already completely prepared to accept Basara’s upcoming acts. Probably due to the effects of the aphrodisiac curse raising her body temperature, Mio’s bodily scent filled Basara’s nose as if tempting him.

“……Onii-chan…”

After that, Mio called for Basara with misty eyes. That, the coquettish call, was Mio’s plea for Basara to subjugate her whenever the curse of the Master-Servant Contract activated.

Basara gulped. He remembered Mio’s softness, and her shy lewd reactions while being pulled into the abyss of pleasure – as well as her seductive and bewitching expression.

Hot blood rushed through him, making him want to thoroughly ravage Mio and once more subjugate her into his obedience.

The moment that thought surfaced, his hands were already moving towards her, intending to caress those large b.r.e.a.s.t.s seemingly begging for his touch—

“—Stop right there.”

“Y-Yuki!” “—…!”

The voice that sounded at close proximity, shocked Basara and Mio to suddenly retreat to the respective ends of the sofa. Yuki seemed to have finished brewing the after-meal tea, and was coldly glaring at Mio while holding onto a tray carrying a tea set.

“…For you to seduce Basara the moment you leave my sight, you really are a b.i.t.c.h.”

“W-Who's the b.i.t.c.h! Really, I wasn’t seducing Basara—“

Just as Mio tried to defend herself after righting her bra straps, the TV screen suddenly turned on.

『……If Basara says so, it’s fine, you know? 』

“Ah~ With this, that doesn’t really seem persuasive~”

“Why did you immediately connect the camera to the TV and play it, Maria!!”

“More importantly, when did you start recording?!”

Beside the furious Mio, Basara felt a headache.

“What are you saying? How could I miss Mio-sama’s erotic actions? It was just for these moments, that I had specially bought a camera with a short boot-up time, you know?”

Mio decided to use force to counter the smug Maria. She ripped off the cable connecting the camera to the TV, and smashed the camera fiercely on the ground. The sound of the camera smas.h.i.+ng into countless small pieces filled the living room.

“Ah————!”

“What about now? You can’t take anymore videos now right?!”

Mio said ruthlessly to Maria who was grabbing her head and screaming tragically, but then suddenly, Maria began to laugh with a low voice. ‘’Ku, ku, ku.’’ She then took out an envelope from somewhere and posed with it.

“Mio-sama, you’re too naive. I’ve already made some precautions, and bought and 5-year warranty extension covering accidental damage for this camera – Hot! Aahh! Isn’t burning the warranty doc.u.ments going too far?!”

“In what way was it, you idiot!! Repent on your actions!”

Maria protested against her trump card being burned away by fire magic by crying, and Mio followed up with scoldings. On her neck, signs of the curse of the Master-Servant Contract had already disappeared.

…What a close call…

Toujou Basara released a sigh in relief, patting his chest with his right hand.

Yuki was also like Basara, releasing a sigh due to being able to successfully stopping that sort of situation from happening.

 

…I really can’t be careless at all.

Nevertheless, Yuki actually knew that Mio wasn’t attempting to simply just seduce Basara.

--She had heard that at the start, she had attempted to chase Basara away from the house so that he won’t be dragged into her matters.

However, Basara had held firm in his desire to protect Mio, and thus Mio also held firm to her desires, and accepted Basara’s intentions; in order to not become a burden to Basara, she had been trying to increase her powers to this day. All these were still fine with her, the problem lay within—

…The method.

Basara and Mio had tied a Master-Servant Contract using magic which could not only let them sense each other’s locations, but also raise their battle potential when they deepened their relations.h.i.+p with each other; but vice-versa, Mio would trigger a curse corresponding to the magic type of the one establis.h.i.+ng the Contract whenever she had any emotions like feeling guilt towards her master.

Hence – since it used Maria’s magic to establish the Contract, the curse that activated on Mio had aphrodisiac effects.

Not long after she moved in, and due to it being quicker for her to see for herself, Maria suddenly pushed Yuki; she and Basara had crashed onto the floor entangled together, causing Mio to become very jealous which then activated the curse. After that, Yuki witnessed the entire process of Basara helping Mio to lift the curse.

Back then the symptoms of the curse were very light, and it was lifted after kneading her b.r.e.a.s.t.s through her s.h.i.+rt; but Mio’s obsequiousness[1] back then while intoxicated in pleasure in her aroused state caused by the aphrodisiac effects of the curse, gave Yuki quite a big shock.

…That was definitely a hyperbole.[2]

But according to Maria, truthfully, at the time when the two of them established the Contract, as well as before they had fought against Kurumi and Takas.h.i.+ and the others, what they had done was incomparable to this, which had thus deepened their Master-Servant relations.h.i.+p one time after another.

That made Yuki utterly shocked. Surely, with the threats from the Current Demon Lord Faction, she would probably need to repeat something like those actions many many times into order to just be able to survive the harsh battles; but however—

…I can’t let Naruse-san get ahead of me again.

Thus when Maria had suggested: [How about you tie a Master-Servant Contract with Basara-san, as Mio-sama did?], Yuki had immediately agreed. And as a result, not able did she get the ability to be able to sense each other’s positions with Basara, there was also another important thing. Since she has already moved in to live with them, Yuki would often relive her close relations.h.i.+p with Basara from the past again; but as Mio would often accidentally witness those intimate moments and then activate the curse, Basara had to commit those intimate body interactions with Mio, and Yuki could do nothing about it. Hence—

…Just a little bit more.

The full moon would be next week. Once she established the Master-Servant Contract with Basara, she would be on equal footing with Mio; in order to prevent the mutual jealousy towards each other from causing trouble to their master, that jealousy wouldn’t activate the curse. As of now, the time Mio had been living together with Basara is leading against Yuki’s by a few months, so she must make up for this gap by any means possible.

…The problem at hand right now are current circ.u.mstances.

Thus, after the fight with Basara and Takas.h.i.+ and the others had ended, Yuki too also began a new leaf of life right here in the Toujou Residence. Mio was probably blaming herself for Basara having to separate with his childhood friends after fighting them without mending their ties; and Yuki could tell that Mio was always nervous when interacting with her. Mio suddenly activating the curse while in the middle of talking about the swimming cla.s.ses, was also most probably part of the aftermath of that.

…But however

Mio already had more than her fair share of pain already, and there was no need to be blaming herself for that; then again… if she were to trigger the curse herself and Yuki were to witness Basara subjugating her in her aroused state, it would be a big problem for her. Thus—

“Basara… I feel that it would be better if you join the swimming cla.s.ses.”

“? Why is that so?”

While serving the tea cups already filled with tea, Yuki said to Basara who seemed surprised:

“Naruse-san seems to be too self-conscious about it. If you were to not join in, she will probably blame herself again and the pervert in her will arise again.”

“W-What are you talking about… I will never do something so embarra.s.sing like that in my life!”

Mio retorted Yuki, aggravated.

“Then again, who's the one being too self-conscious!?”

“Mio-sama, please don’t put too much force into your hands, or my life will be in critical danger!”

While being grabbed by Mio by her collar, Maria raised her hand in panic, and said:

“Speaking of which… I too think that Basara-san should attend the swimming cla.s.ses. We currently still do not know how the current state of affairs around Mio-sama will evolve; there is no guarantee that there would be no difficulties in the cla.s.ses or circ.u.mstances forcing absence from school in the future. Thus, I believe that regularly showing up whenever possible is the best option for now. If not—“

Maria then continued:

“If Basara-san where to be retained for the academic year while Mio-sama and everyone else gets promoted, it would create a weird feeling around it with Basara-san as the onii-chan… Hold on, doesn’t that situation sounds nice?”

“Nice your head. But you’re right, that situation would be bad. If I were to be retained, making friends would be even more difficult… perhaps it might be better if I do attend. But even if we were to order the swimwear now, would it arrive in time for the swimming cla.s.s next week?”

Basara said, helplessly.

–Indeed, Yuki thought. In the past when she and a few other girls from Cla.s.s B lost their swimsuits, they had asked their teacher-in-charge to help them order new ones from the school’s supplier, and it took a grand total of two weeks before they received their new swimsuits. Maria then answered:

“Don’t worry, Basara-san. I do know which factory is the one appointed to produce swimwear for Hijirigasaka Academy. Once the order is made online, the goods will be delivered within three working days, so it’ll definitely be in time.”

“Really? That’ll be great… why do you even know something like that?”

Maria then answered the puzzled Basara while giggling:

“You see, Mio-sama’s b.r.e.a.s.t.s are different from a normal person’s~. So for the normal goods bought outside, part of the chest or hip areas wouldn’t fit… isn’t that right, Mio-sama~~?”

“W-Why are you leaking my info out… you dimwit!”

After scolding Maria while red-faced, she awkwardly turned to Basara and Yuki and said:

“…During the regular body check in spring, Hasegawa-sensei had advised me that if I have sufficient funds at hand, I can make an order directly at the factory. Her b.r.e.a.s.t.s were also very large, so her racing swimsuit had to be custom-ordered online, and so she was very understanding about it.”

But—

“When I visited their website, I realised that custom orders were pretty expensive, so I had not ordered a new one in the end… Although it would be just for making a swimsuit that fits me, I am not an athlete, so I don’t want to disclose my three sizes to anyone else. If I do order one, I’ll have to make a visit down to the factory to make measurements, as well as let them have some photos of me, you know?”

Mio sighed, and continued:

“And so I had always been buying stuff directly from the stores, and then I would have Maria use magic to make it fit my body. This process is much quicker too.”

“…No wonder Naruse-san was wearing such a weird swimsuit. I had always suspected that there was something behind it.”

Hearing Mio’s explanation, the suspicions that Yuki had been harbouring since the first semester’s swimming cla.s.ses were answered. Just then—

“Although using magic to conveniently settle stuff isn’t really deserving of praise, I’ll let it slide. It wasn’t something you had been forced to do due to the discomfort.”

Basara spoke.

“Umm, Maria. Tell me the website later, I’ll order one.”

“I understand… Oh right, I just remembered that I have something to ask.”

After nodding while answering Basara, Maria then suddenly turned to Mio and said:

“Mio-sama, how about you buy another racing swimsuit?”

“Why should I?”

Towards the puzzled Mio, Mara began to laugh. Ufufu

“Really, Mio-sama… Stop pretending~. You’ve already done the Master-Servant Contract with Basara-san and become his subordinate, and he had went crazy so many times with your b.r.e.a.s.t.s for so long every time he subjugated you… your grand and majestic b.r.e.a.s.t.s must have grown even more, to the point where it’s already overflowing from your current swimsuit. Isn’t that right~?”

“ ! — …”

Being said as such by Maria, Mio’s whole face turned red, and her hands hurriedly wrapped around her chest area.

This reaction, was basically just confessing that what Maria had said was the truth.

…Just as I suspected.

Yuki too had observed what Maria had just said. Those gigantic mammaries… she had thought that she was still in the middle of developing her a.s.sets which caused her b.r.e.a.s.t.s to keep growing, but it appears that they were groped to their sizes by Basara.

Unforgivable… Just as the flames of jealousy and envy ignited within Yuki’s heart—

“Ara~? Really, Mio-sama, why do you seem so tense? How could I, as a succubus, not notice such an alluring change? Or in alternate words, even Basara-san had noticed, so of course I already had!”

“Eh——!?”

Maria’s words caused Mio to look at Basara in shock.

“……Well…”

Basara’s face reddened, and he looked away from Mio, embarra.s.sed.

“……!!”

Seeing this reaction, not only just Mio’s face – even her neck too turned pink.

“What are you surprised about…? Basara-san had already groped Mio-sama’s b.r.e.a.s.t.s so many times, so of course he would notice any changes in its feel, size and texture.”

Maria then continued after taking out a measuring tape from somewhere:

Clothes that do not fit your body, will cause the beauty of your b.r.e.a.s.t.s with such rare beauty to disappear. Why not take the opportunity now and buy a new swimsuit, and find a suitable home for each of your super lewd b.r.e.a.s.t.s! Come, Mio-sama, it’s all for your b.r.e.a.s.t.s! For starters, please expose your gigantic b.r.e.a.s.t.s!”

“Why are you so d.a.m.n meddlesome!? I’m telling you right now, I’m very happy with my current swimsuit!”

Mio retorted:

“Speaking of which, let’s say if… umm, my b.r.e.a.s.t.s really had become bigger, causing me to no longer fit into my swimsuit, it’s sizes can be changed with magic, so there’s no need at all to buy a new one!”

“I see… Since Mio-sama prefers to keep status quo, then I guess I’m fine with it.”

Maria sighed deeply, and then turned to Yuki to ask:

“Then, Yuki-san – what about it? Do you want to buy a new swimsuit?”

“…Me?”

“There isn’t a need, right…? Yuki regularly attends the swimming cla.s.ses, and thus already has her own swimsuit.”

“That’s right, and what’s more, there isn’t a need at all since Nonaka-san’s sizes hasn’t changed!”

“Indeed, Yuki-san doesn’t seem to have any problems with her current swimsuit…”

Maria nodded while agreeing with Mio and Basara and said:

“But however… a ready-made swimsuit at the end of the day, is still a ready-made swimsuit. If one perfectly fitting Yuki-san’s body were to be made, the contrasting curves of her body can be made even more beautiful… Just like Mio-sama’s.”

And then—

“A female would definitely want to make herself prettier whenever possible, to the point where you could say that it is an instinct… Additionally, Yuki-san has already considered doing a Master-Servant Contract with Basara-san just like Mio-sama, isn’t that right? Would you like to have your current swimsuit used specifically just for the swimming cla.s.ses and buy another swimsuit to make yourself even prettier, one that is specially to be seen by a master like Basara?”

“Hold on for a minute, I haven’t completely agreed to making a Master-Servant Contract with Yuki—“

“If I buy a new swimsuit, and become even prettier… will Basara be happy?”

Yuki interrupted Basara interrupting Maria, and asked Maria.

“That’s for sure… No matter what Basara might say, he is a male after all. As long as you leave the buying to me, I will guarantee you that he will immediately forget about the gigantic b.r.e.a.s.t.s squeezed into an extremely small swimsuit that has been groped virtually to shreds despite how the lowly girl saying that everything’s fine!”

“Y-You…!”

While ignoring Mio being provoked by Maria to the point of almost boiling over, Yuki strongly nodded, and said.

“…Alright. I’ll be buying one too – so, please get me one that’ll bring my femininity even higher than Naruse-san’s.”

 

Part 2

Coming to the week after.

On the eve of the girl’s swimming cla.s.ses that were one day before the boy’s, when Mio and Yuki reached home after cla.s.ses ended, they realised Basara’s and Yuki’s swimsuits that were ordered online have arrived.

“Now, before tomorrow’s cla.s.s, let’s try it on right now!”

Maria eagerly urged Yuki to try it, and even insisted that it wasn’t fair for Yuki to be the only one trying it. In the end, it turned out to be everyone having to accompany Yuki and try it on together.

“I can’t take it anymore… Just how did it even become like this?”

Mio went back to her room to retrieve her racing swimsuit bought during springtime, and grumbled while heading towards the dressing room on the first floor. There weren’t any changes in the sizes of Basara’s swimming trunks, and was already waiting in the living room as per their request, waiting for the girls to finish changing in the dressing room.

--As Mio had not bought a new swimsuit, there wasn’t actually a need for her to try on her swimsuit; what had made her accept Maria’s suggestion, was the feeling that something dangerous would happen if Yuki changes into her new swimsuit.

…Because.

During her first swimming cla.s.s – Mio’s sights were completely captured by Yuki.

Although they were obviously wearing the same swimsuit, Yuki was exuding a beauty on a different level from Mio and the other cla.s.smates, which captured the breathes of everyone. Since even Mio of the same gender had such a reaction, Basara was probably even more vulnerable. However—

‘’…I-I can’t lose…’’

While harbouring compet.i.tiveness towards Yuki, she opened the room to the dressing room and entered.

“Yuki-san, please be careful… Slowly insert the blade between the cloth and the sewings.”

“…Like this?”

After that,Yuki, who Mio thought had already finished changing, followed Maria’s instructions, and did something to her own swimsuit.

“That’s right, just like that, slowly move the blade horizontally… Beautiful!”

At the same time Maria let out praise, something white descended from Yuki’s swimsuit and landed on the ground. After that, Yuki let out a sigh as if a big load had been lifted from her heart.

“…What are you two even doing?”

‘’Are they removing the nametag?’’ – Originally thinking this, Mio inadvertently[3] took a look at the thing that fell onto the floor, and then immediately understood what it truly was, she shouted, shocked:

“—Oi! What in the world do you even think you are even doing!?”

What Yuki had cut off wasn’t the nametag, but something that was sewn onto the inner portion of the crotch area of the swimsuit that prevented the shape of an ‘’important place’’ from showing up.

Towards the speechless Mio, Maria raised an index finger with a ‘’s.h.i.+’’, and said:

“Mio-sama, please keep it down… Yuki-san worked so hard to prepare a surprise for Basara-san, and it’ll all go down the drain if it was ruined by a large sound disturbing her, right?”

“A surprise…? Hold on, Nonaka, you do know what your swimsuit will turn out like, do you?”

Mio asked, hardly able to believe what she saw. While holding onto a handicraft knife in one hand, Yuki nodded and said: ‘Of course.’

“Maria was really kind… When I asked her what I should do to make Basara happy, she taught me everything.”

As she said that, both breast cups fell onto the floor.

“ !! –Maria!”

Mio glared at Maria, the culprit, but the one to blame only smiled fearlessly and said:

“Oya? What’s wrong, Mio-sama? Yuki-san said that she wished to make the modifications which would make Basara as happy as possible, and I had not lied to her. Isn’t transparent underwear more erotic? That’s the case for swimsuits too. To make the adolescent Basara happy, this is of course the most simple and sure-fire way.”

‘’How’s it?’’

“I have another handicraft knife prepared. Mio-sama can use it too if she doesn’t mind.”

“W-What are you joking on about! Nonaka has got another swimsuit, but I only have got this one! If I cut them off now, how do you expect me to go for tomorrow’s swimming cla.s.s!?”

“I knew you would say that, so this Maria here… had even bought Mio-sama’s share too! ‘’Jang~’’”

After Mio shouted with a red face, Maria raised both her hands holding on to a brand new swimsuit.

“My my… You as Basara-san’s servant, are supposed to be eagerly doing things like this, how could you lose to Yuki-san…? Mio-sama, could it be, that you are experiencing shyness?”

“Anyone would experience shyness if they wear such a swimsuit!”

Mio’s straight retort came as a surprise outside of Yuki’s expected reaction.

“Basara will become happy, so why won’t you do it? Why did you even make a Master-Servant Contract with Basara for then?”

“It was of course to be able to sense each other’s locations in emergencies!”

“I can’t believe it. Basara had sacrificed so much just to protect Mio-sama… yet Mio-sama can’t even accept some shame for him.”

“ ! …I-I…”

“Forget it, I guess this is fine too. Basara-san is such a nice person, so even if Mio-sama wear a normal swimsuit, he will still give you beautiful praises. But then, comparing Mio-sama with a swimsuit as normal as a stone by the road with Yuki-san’s swimsuit which she had modified after mustering the courage just for Basara-san, which do you think would attract his eyes more? That will be known once the both of you go out there.”

Maria purposely said towards the Mio with a troubled expression while sighing.

“Come, Yuki-san. Let’s leave this blockhead alone, and quickly go show Basara-san your new swimsuit. I had specially prepared another swimsuit just for this moment, so… who knows, by then, there might some pity for a certain wretch wearing just a normal swimsuit, so please do your best to ignore that. That person’s body seem to be a bit shameful, so please do excuse her.”

“Nn… I understand.”

After nodding to each other, Maria and Yuki then took off their clothes to change into their modified swimsuits.

Seeing herself being crowded out, Mio finally couldn’t take it anymore, and stretched out a hand to Maria with her shoulders trembling.

“………Okay, Maria, lend me that handicraft knife…”

And said with tears and semi-abandonment.

“Since that’s how you say it, I’ll fight with you…!”

 

Part 3

Toujou Basara was waiting in the living room.

Following Maria’s instructions, he had changed into his delivered swimming trunks, and wore a s.h.i.+rt.

“…This feels like a punishment game.”

After he had changed into the swimming trunks, Basara had already been waiting in the living room alone for nearly an hour.

He had utilized this time by doing his usual weight training done every day. But even after finis.h.i.+ng the whole routine, they still haven’t appeared.

“Can’t help it… Let’s do it again.”

“My~ Sorry to keep you waiting, Basara-san. I had spent some time helping Mio-sama and Yuki-san. You definitely won’t be disappointed, this’ll definitely be worth the wait!”

Just as Basar was about to begin the second round, Maria entered the living room while smiling, and pointed a finger at him.

“…You seem too happy. Speaking of which, what’s with what you’re wearing?”

The reason Basara had to ask, was because of the deep-blue student swimsuit Maria was wearing.

Although it was the swimsuit everybody had agreed to wear in school, it was a bit strange for Maria to be wearing one when she did not go to school.

“The swimsuit most suitable to show off this loli-succubus’s body type, is of course none other than the student’s swimsuit… Basara-san, you should enrich the knowledge you should know at your age, or I’ll have headaches.”

“The information you want me to remember are obviously inappropriate… Can you please not use messed-up things like subjugation games as a textbook?”

“That I will have to say no. Even if it’s Basara-san, I can’t allow you to say messed-up things as you wish, or else this gentle person will get angry, you know? In what ways are the subjugation games wrong!?”

“The problem is the minimum age needed!”

Having an outburst just for lewd games, just what kind of small girl are you?

“…Then what about Mio and Yuki? Are they finished yet?”

“Ah, I almost forgot… Hearing Basara say that just now, I got a little distracted and almost forgot to ask them to come in.”

As Maria said that, both young girls walked into the living room from the corridor.

「——————」

In that moment they came into view, Toujou Basara suddenly stopped breathing.

This was his first time seeing the both of them in a racing swimsuit, and it got all of his attention.

“………” “………”

Both of them were wearing the same swimsuit, with a coy[4] air around them.

--But yet, Basara’s eyes could not look away from them.

Lately, Mio’s b.r.e.a.s.t.s had gotten bigger, and the surprising increase in her proportions added to her alluring charms.

The stunning seductive curves of her hips and thighs, accented to her exceptional figure.

The appearances of the two of them in swimsuits, completely s.n.a.t.c.hed away Basara’s thoughts and sights.

“……!”

And then, Toujou Basara soon understood what Maria was talking about with the ‘spent a little more time’, as well as the reason why noth Mio and Yuki seemed so shy.

“How is this, Basara-san? Was the destructive power of Mio-sama’s and Yuki-san’s tight swimsuits too much? Aren’t the both of them beautiful?”

「「…………！」」

Hearing Maria say this while giggling, Mio and Yuki’s both trembled with shyness.

--Despite that, Toujou Basara’s eyes still continued to look at the both of them.

At the b.u.mps showing up on the swimsuits at the tips of their b.r.e.a.s.t.s, as well as that crevice showing up between their thighs.

While holding her very red face up, Naruse Mio felt Basara’s gaze on her body.

While being started at by Basara, she felt his attention gathering in ‘’those places’’.

‘’…D-Don’t…!’’

Because of that, she was completely unable to stop the tips of her b.r.e.a.s.t.s from standing up and become harder and harder under Basara’s gzes.

And down there, there was also a reaction too – thinking this, she had a very strong urge to cover that place.

--But Mio fought to hold that urge back, because Yuki was right beside her.

It wasn’t just Mio alone who had cut off her breast pads and the lining ‘’there’’ and had Maria use magic to have the swimsuit hug tightly to her body form. Yuki too, was also under the same conditions – standing there right beside her.

The swimsuit on her breast area also had the same extrusions, and her private area also had the same modifications.

Additionally – she was currently just as shy, like Mio was.

Despite what she was bearing, she was still standing there bravely showing off everything.

“……!”

Thus she mustered her feelings of not wanting to lose to her, she continued to bear with it.

“…How is this, Basara-san? Aren’t the both of them beautiful?”

“ ! …Uh, of course… Well, this…!”

The question Maria suddenly pitch at him, caused Basara to suddenly speak incoherently.

‘’…Aah…’’

Basara’s fl.u.s.tered reaction, slightly eased Mio’s and Yuki’s nervousness; which despite their shyness, allowing them to regain some of their calm and liveliness and tease Basara:

“Basara… just where of Nonaka’s and my body did you look at?” “…Answer me honestly, Basara/”

“Uh, with the two of you wearing that… of course I would see.”

Hearing Basara say so as if surrendering, Mio was very happy. With Basara usually subjugating her under his hands, occasionally teasing him was pretty interesting.

“—it’s about time. Let’s go to the bathroom, shall we?”

At that moment, Maria said this.

“W-Why are we going to the bathroom?”

Maria giggled while answering Basara’s doubts:

“No need to be worried. This, I have already discussed it with Mio-sama and Yuki-san already.”

“ ! …You really agreed?”

“……Nn,” “Its fine…”

Mo and Yuki nodded strongly towards Basara looking at them surprised.

“—Come, Basara-san, this way please. The happy period[5] is about to start♥”

With that, led by Maria, Basara, Mio and Yuki headed to the bathroom.

--The reason they took so long before coming to the living room, was because they done not only just the modifications to their swimsuits.

Other than tomorrow’s girls’ swimming cla.s.s, there was also something important that will be done tomorrow night.

And that is, a magic ritual that can be only on full moon nights in the Human Realm – Master-Servant Contract.

The ones doing the contract were Basara and Yuki. But before the contract took place, Maria had raised another request, and that is—

“---later, everyone please deepen your relations.h.i.+ps with your master nicely in the bathroom.”

Midway on the way to the bathroom, Maria turned around and said:

“This is something that tomorrow, Basara-san and Yuki-san must do before doing the Master-Servant Contract.”

“Stop right there… What do you mean with that?”

“If Yuki-san were to also have the Master-Servant Contract with Basara, there will be a need for Mio-sama who is also a subordinate to the same master to interact in harmony.”

Maria once again repeated what she had already said to Mio and Yuki to Basara who had doubts:

“Not only just Yuki-san, Mio-sama and Basara-san must know about it too. The two of you must wholeheartedly recognise Yuki-san as Basara-san’s new subordinate, and accept her joining you. In the future, there will probably be many strong foes waiting for us; if any of our actions as a team goes wrong, there will be life-or-death perils. I’ll say it again, Mio-sama and Yuki-san has already agreed to this – so right now, it’s only Basara-san left that needs to decide.”

“Uh, but I…”

“I understand. Basara-san is still unsure if you should let Yuki-san do the Master-Servant Contract, right?”

Maria nodded towards Basara’s whose expression became tangled-up and said:

“—that’s why, Basara-san, why not think about it from another angle? Let’s use this time, pretending that you two have already the Contract, and see of there would be any problems.”

“Test…?”

Basara asked while frowning and Maria who was wearing a swimsuit answered while nodding:

“I would say that what you are probably worried about is about the Master-Servant Contract that is done using my magic – would there be a day whee you or Yuki-san, or even Mio-sama where you would regret the decision?”

“………”

This question, was answered with an affirmative with Basara’s silence.

--the Master-Servant Contract was using the Demon Race’s magic, so when Basara and Yuki had to do the Contract, it could only be done using Mio’s or Maria’s magic power. If it was using Mio who had inherited the previous Demon Lord’s power, Yuki might just possibly be flattened into minced meat when the curse activated; in other words, once Yuki establishes a Master-Servant Contract with Basara, there would be no other choice other than being bound by the aphrodisiac effects due to Maria’s succubus magic like Mio.

However – when the curse with unknown varying strengths activates, Yuki does not know just what will happen to her.

From the viewpoint of battle power, there was no wrongs in Mio establis.h.i.+ng a Master-Servant Contract. If her battle power had not been raised by the Master-Servant Contract, the probability of them winning against Takas.h.i.+ with his [Byakko] and the others where very little.

‘’…But,’’

Just like a few days ago in the living room where Mio took the initiative to hug Basara, it was something that was never expected from before making the Master-Servant Contract.

--it goes without saying, that that reaction of Mio’s was influenced by the aphrodisiac curse.

But before Basara had done the Contract with Mio, even if it was just being playful and naughty, he would never even dare to hug her.

And recently, he had begun to experience a particular exclusive emotion for Mio.

Other than wis.h.i.+ng to have Mio as a sister and family that he would protect – occasionally a particular impulse would well up, making him want to monopolize all of Mio.

Pf course – to a male of around Basara’s age, this might very well be normal. It was already risqué enough with just having to live together with a female unrelated by blood, and the bar was further raised by the fact that Mio and Maria were such beauties. For just the fact that he had been able to preserve himself to this day, commendation was already long due.

Additionally, with all that’s happened, he could definitely their bonds and trust becoming much stronger. For surviving the future battles and breaking through various difficult situations, it helps a lot.

--But despite that, as there was a need to use the body’s sensations of pleasure to stimulate the consciousness of subjugation and deepen their relations.h.i.+p, the relation between the two of them was no longer that of a normal family or siblings. That is an undeniable truth.

‘’…However,’’

Recently, when when Yuki had suddenly disappeared while in the middle of a date in the heart of the downtown area, Basara had a taste of anxiousness that almost made him lose his mind. In order to win against the strong foes in the future, in order to protect Mio, Maria and Yuki, establis.h.i.+ng a Master-Servant Contract with Yuki was undoubtedly an effective measure.

‘’…But,’’

After repelling Takas.h.i.+ and the others, Basara had originally thought that he would never see Yuki again. But yet she is living right here right now, so finally there is a chance for them to recover the relations.h.i.+p they had in the past.

Under this situation, if he were to establish the Master-Servant Contract with Yuki and use pleasre to subjugate her – despite how the fact that they had grew up together would never change, he might not be able to recover the relations.h.i.+p they had in the past – with this thought in his mind, Basara couldn’t make his decision.

“—therefore, before actually doing the Master-Servant Contract, let’s do a small test”

Maria said:

“To test if she really has no resistance towards becoming your subordinate… to see if you can really subjugate her, as well as to see if Mio-sama is able to accept that relations.h.i.+p between the both of you.”

Perhaps Maria was planning on – having Yuki witness the things they Basra had done with them before – and have her personally experience them, and understand the true aspects to the Master-Servant Contract. To deepen a relation between the master and a subordinate, the master needs to have the subordinate show yielding, which is moch more intense than dispelling the curse whenever it activates. Maria wants to do such a test before the actual event tomorrow, to observe if there would be any problems if Basara and Yuki were to establish a Master-Servant Contract.

“……I understand.”

Thus, Basara nodded. After this, everything will probably go as usual, with everyone being forced to do something which makes the succubus excited.”

Despite how reluctant he was, Basara had agreed to it. If the Contract were to be done when he can’t even do something like this – he will definitely soon regret his decisions.

 

Part 4

“Now then, Basara-san, please sit on this stool first… Mio-sama and Yuki-san, please get ready to wash his body.

“……!”

Hearing Maria say that, Naruse Mio gulped. When Mio and Yuki were still changing in the dressing room, they were instructed by Maria on how they should wash Basara. Thus—

‘’…Just this much, is nothing…!’’

Mio attempted to rouse her compet.i.tive spirit. Now Basara was not a Hero, but yet he got embroiled into her fight with the Current Demon Lord Faction, and even had to fight against his childhood playmates.

Even on Mio’s school and daily lives, Basara had always been worrying for her, and just accepting all of the restrictions that came with caring for her. Hence, no matter what, Mio must not let herself harbour guilt towards him, and repay him for all that he has done.

‘’…But,’’

No matter what, Mio does not wish to be just on the receiving end of Basara’s warmth and protection.

If she could do anything that would make Basara happy, Mio was will to do it.

--And Yuki had the same thought.

When that tragedy happened five years ago, Yuki’s life was saved by Basara, yet she could only just look from the side-lines while he received the fate of being exiled from the Village, and she seemed regretful about it to this day; previously when fighting with Takas.h.i.+ and Kurumi, Basara was plenty worried about her. She probably thought she won’t be able to easily pay that debt just by simply doing a Master-Servant Contract with him, and though she had said that she would help in whatever little way she could, that sacrifice was nothing in comparison. Of course, apart from that, she had also said that it wasn’t fair that Mio was the only one being subjugated with Basara’s hands and had a Master-Servant Contract with him.

‘’…That’s right.’’

No matter if whether it was Mio or Yuki, Basara had sacrificed too much for both of them.

This was an opportunity to slightly repay him. Saying all of that to herself—

“ ! …I’m starting, Nonaka…” “……No problems here.”

Mio started first, and Yuki responded from her side – after that while facing each other, the both of them began to pull away the shoulder straps of their own swimsuits.

“ ! ———— “

Basara who witnessed that while sitting on the bathroom stool, gulped a breath of air. But as he had probably guessed from what Maria had said just now on what Mio and Yuki would probably do, despite how red his face got, he did not look away or attempt to stop them. Basara needed to adopt the att.i.tude as a master, and accept the things Mio as his subordinate would do for him, as well as to access whether Yuki could become his subordinate.

“……!”

What that thought, Mio and Yuki can’t care about being shy and embarra.s.sed and hope that they would be able to even repay Basara’s intentions; once their arms were extracted from the shoulder straps, they used both their hands to grab the swimsuit at the chest area, and pulled it downwards. Both of their b.r.e.a.s.t.s then burst out into the air, like a dam bursting – exposing even the tips of their b.r.e.a.s.t.s. After that, after pulling the swimsuit downwards until their navels were about to be exposed—

‘’…! …Aahh…’’

It appeared in Basara’s sights. Thinking this, the insides of Mio’s body became hotter from the shyness.

And began to think about what she will be doing to Basara a little later, as well as what he will be doing to her.

However, Mio, at the same time, was determined to do it. She was already this far in, and it was already too late to be pulling out this this.

“………”

Thus, Mio opened the cap of the shower gel bottle and poured its contents onto her b.r.e.a.s.t.s, and the viscous liquid then completely covered her b.r.e.a.s.t.s. However, she did not immediately head towards Basara, but instead turn towards Yuki who had also similarily exposed her b.r.e.a.s.t.s.

“Nonaka..”

“…Nn.”

Yuki nodded, and kneeled down before Mio; Mio then kneeled down too, looking into the face that was just as red as her’s. After that, before Basara’s eyes, they wrapped their arms around each other’s backs – while tightly hugging each other, and at an angle which could be seen clearly be Basara, they began to indecently rub each other’s b.r.e.a.s.t.s with their own b.r.e.a.s.t.s.

“Wha…!”

“What is it, Basara-san…? What is there to be surprised about?”

Maria giggled while saying towards the shocked Basara:

“Providing visual entertainment to their master, is also a subordinate’s job, isn’t it…?”

What Mio and Yuki were doing right now, was exactly just that. The two of them definitely had no interest in this area.

‘’But as long as Basara is happy’’ – while harbouring such a simple thought, she continuously rubbed her b.r.e.a.s.t.s slippery from the shower gel with Yuki’s. Not only were their b.r.e.a.s.t.s pressed into sensational shapes, piles of foam were also produced with various sounds. ‘’Chuguchu’’

‘’…! …No way, I-I…!”

It only just tickled a little, but because Basara was seeing this – a bundle of sweet hotness gathered somewhere deep with Mio and Yuki’s bodies, causing the tips of their b.r.e.a.s.t.s to gradually stress their presence.

“ ! …Naruse-san, I…’’

At a loss, Yuki asked shyly. It was only then, did Mio see that teenage girl who had yet to do the Master-Servant Contract and was unfamiliar with the body’s pleasure, had a s.e.xy coquettish expression on her face.

“Nonaka…”

For the usually expressionless Yuki, this expression was one that was hardly imaginale. This also made Mio understand, just how lewd the stuff she was doing was.

‘’…T-This is all for Basara…’’

Despite that, tha thought allowed Mio to do the thing Maria had told her before. She held up her b.r.e.a.s.t.s, and after positioning the tips of each other’s b.r.e.a.s.t.s against each other, she began to rub them against each other by drawing circles.

“Nn …Aa… Don, nnn…. Fu…” “ ! …Aaah, haaa…….Nn!”

Both Mio and Yuki were not familiar with this action, so there were some slip-ups at the start; very soon they caught the trick behind it, and it became fairly easy for them. In the turn of an eye, there was already no room for the four tips of slip-up… and thus started to pant with the embarra.s.sment and excitement from Basara’s gaze.

“Naruse-san…” “…Nn.”

At that moment, Mio and Yuki’s legs wrapped around each other’s waist.

After that, they poured even more shower gel, and rub each other’s b.r.e.a.s.t.s’ tips more intensely.

“Ah… ya, nn… Haahh…!” “Yaah…Nn, Fu…..Aahhnn!”

While creating faint pleasure, the both of them continued to intensely rub their covered b.r.e.a.s.t.s against each other’s. Very soon, with the sweet hot pleasure s...o...b..lling, a pile of foam gathered on their soft b.r.e.a.s.t.s. When they released their entangled legs after that, they made some s.p.a.ce between them.

“Basara… Come.”

With an intoxicated gaze, the young youth watching them was then enticed.

“………”

Basara said nothing. He too, like Mio and the others, had already made up his mind long ago. He silently got up from the stool, and sat down in between the legs of both of them.

“I’m starting now…” “…Basara, we’ll help wash you.”

The feeling that there wasn’t a need for words, caused both Mio and Yuki to say both happily and shyly, and after that, while enclosing in on Basara with their legs – they used their own bodies to scrub Basara’s whole body. The softness of the b.r.e.a.s.t.s, as well as the stiffness of their tips – were all utilised with reservation, scrubbing Basara lewdly.

“Aahh… Ya, Nnu… Fuuaahh♥”

At that moment, an ecstasy-filled breath escaped from Mio’s mouth.

‘’…No way, now that the person is Basara…?’’

Mio realised, that the feeling now was completely different from when she rubbed her b.r.e.a.s.t.s against Yuki.

This sensation was obviously not the same as the sense of itching from just now, it instead was a hot and comfortable feeling – a result most probably due to Mio’s body developing further. Hence, compared to Yuki who boldly washed Basara despite her shyness, Mio’s movements were not very smooth. Right now, from the touch or servicing of her master, the ability to derive pleasure from those activities were already created within her. This fact that makes people tremble for reasons other than embarra.s.sment, also allowed Mio to dedicate herself to Basara who so loved her, making her secretly feel a joy close to proudness.

But as she thought this, Yuki already came to Basara’s back—

“…Basara, I’ll help you wash your back.”

And Mio could only just watch as Yuki began rubbing her b.r.e.a.s.t.s against Basara’s back.

“The most importan position of serving her master, was stolen by her simply just like that.

“Oya oya, Mio-sama… You had the first strike stolen from you when your mind wandered, just what are you even doing as the senior?”

“ ! ……”

Maria picked on Mio with a sarcastic smile, causing her to bite her lip in dissatisfaction, and said:

“Please, Basara… Wash your hands with your b.r.e.a.s.t.s.”

Sitting down on Basara’s legs while facing him, She then pulled his wrists towards her own b.r.e.a.s.t.s.

Mio was not using her b.r.e.a.s.t.s to wash him – for something like that, she had already long before wrapped her b.r.e.a.s.t.s around his arm and cleansed all the way to his wrists.

After letting Basara grab her soap-covered b.r.e.a.s.t.s, Mio once again put her hands over his, and said:

“Nn… It’s fine. Basara’s palms and fingers… you can use my b.r.e.a.s.t.s to clean them thoroughly.”

Mio’s thoughts and intentions, Basara seemed to understand them with his brief moment of silence,

“……I’m beginning.”

And he said, as he started to begin kneading Mio’s b.r.e.a.s.t.s. Seeing her b.r.e.a.s.t.s overflowing from his hands, and the various obscene shapes created by each and evey one of Basara’s movements—

“No—Ha, Fuaaaaaaaahhn♥”

Mio who derived intense pleasure from firstly cCreating lots of foam from rubbing against Yuki’s, and then from being rubbed against Basara, suddenly stiffened up in a moment, achieving climax.

“A-Are you alright?”

Basara seemed to want to stop at that moment, his hands about to leave Mio’s b.r.e.a.s.t.s,

“Don’t stop halfway, continue… I have to thoroughly wash your hands…!”

Yuki was still was.h.i.+ng Basara’s back now, so Mio can’t show any signs of weakness before she does.

After that, Basara nodded towards Mio who begged – and then renewed his action of was.h.i.+ng his hands with Mio’s b.r.e.a.s.t.s.

“Ah♥ Fuahhh!? Ya, ha – Fuaahhh♥ Ha, Aaahhhh♥”

Thus, Mio was swallowed by the torrent of the climax in that moment, saucily arching her back on Basara’s legs. With her hips shaking admist the intense pleasure, she was rushed up to climax again and again.

Nevertheless, no matter what Mio would say now, the Basara right now would not stop his actions.

Hence – this situation continued on for five minutes, and the pleasure dissolved Mio’s reasoning, leaving her only able to pant while on Basara’s legs.

“Ah… Nn… Fu, ah…Uu… Fu…”

“You can’t be like this, Mio-sama… You are someone who has to serve Basara-san, so how can you be acting so spoiled towards him?”

Seeing this, Maria revealed a mocking smile, and said:

“For Mio-sama to be acting like this, I believe a punishment is needed.”

“…Punish…ment…?”

Mio asked with her eyes unfocused, but Maria ignored her, and said:

“Basara-san, Yuki-san… Can I say something to you?”

After that, she said something into Basara’s and Yuki’s ear, and the result—

“That… wouldn’t it be too much?”

“…I object too. Although I don’t feel it would be too much, I do not wish to become a tool.”

Both Basara and Yuki visibly seemed to be troubled, but Maria gave no compromise.

“Such an allocation of a.s.signment can’t be helped… Subjugating a subordinate, is Basara’s job; and as Yuki-san is not yet officially Basara-san’s subordinate, only Mio-sama can display a situation of being subjugated. Yuki-san needs to learn from the process of a.s.sisting your future master Basara-san, just what kind of a thing doing a Master-Servant Contract as a subordinate from your senior Mio-sama who had already done a Master-Servant Contract. a.s.sisting your master to even more shockingly, deeply, and effectively subjugate a subordinate, is also one of the important jobs of a subordinate.”

Maria then continued:

“Basara-san… Don’t want to see what would happen if Mio-sama were to ever meet such a situation? Didn’t you want to have no regrets at all after doing a Master-Servant Contract with Yuki-san – if you aren’t willing to do something like this, who would you know if there would be any problems?&
