"Ara... A date with your girlfriend, is it?" Kaoruko's voice was a silken purr, a knowing smile curving her lips as she observed the scene.
"W-Well... something like that... ahaha..." I forced a dry, brittle laugh past the lump in my throat.
"In that case, you won't be staying for lunch today?"
"No. We've planned to meet after we've both eaten, so... if it's no trouble, I'd like to partake as usual."
"Fufufu... Understood. I shall have it prepared for you."
Kaoruko's smile remained placid, her agreement a smooth acceptance of my lie. Though the estate housed a full staff of servants, meals were typically taken only by Kaoruko and Toka.
To alleviate even a fraction of their solitude, I made it a point to seldom refuse their hospitality.
"Very well. I look forward to today's lesson, Hirokazu-sama."
With a graceful bow, Kaoruko glided from the room, the soft whisper of her kimono trailing behind her.
"Alright, let's get started, Toka-chan."
"Mmph..."
'Huh?'
I addressed the girl now seated at the study desk, but her only response was a petulant puff of her cheeks. She stared rigidly forward, her attention fixed on the open notebook before her.
I had, of course, previously informed Toka of my relationship status.
After closing the door behind Kaoruko, I settled into the chair placed beside the desk.
The study materials were laid out, perfectly prepared—notebooks open, reference books at the ready—yet Toka refused to even pick up her pen.
"Um... I'd like to start whenever you're ready..."
I prompting was met with stony silence; Toka remained a statue of puffed-cheek defiance.
'Sigh... What am I supposed to do with her...?'
"Sensei..." she finally whispered.
"Hm?"
"On this date... after your lunch... will you be doing things like... kissing? And... lewd things?"
"Huh!?"
The sheer audacity of the question, spilling so bluntly from Toka's innocent lips, made my jaw go slack. I snapped my gaze to her face; her expression was deadly serious, her eyes boring into me with an intensity that stole my breath.
"I-I mean... I suppose... depending on the mood, such things could happen. But it's not a foregone conclusion, you know!"
'Though, given that this is Nino's first time experiencing it all... sex is definitely happening.'
"So... if the mood is right, you will do them?"
"W-Well... Look, this conversation is inappropriate. Come on, let's just start the lesson."
I reached for the reference book, hoping to redirect the suffocating tension. Instead, Toka rose from her seat with a sudden, decisive motion.
"Toka-chan?"
"Even I...!"
"?"
Before I could question her, Toka's hands flew to the shoulders of her dress. In one fluid, shocking motion, she pulled it down, the fabric pooling at her feet with a whisper of cloth.
"H-Hey—!?"
My head snapped to the side, my eyes instinctively averting from the sudden expanse of bare skin.
"What are you doing all of a sudden!?"
"Please... Sensei... look at me..."
"No! That's not—!"
"Please!"
The desperate, heart-wrenching plea in her voice made me falter. My resolve to look away crumbled. Slowly, against every screaming instinct of propriety, I turned my head back toward her.
There stood Toka, her spine ramrod straight despite the vivid blush staining her cheeks. She was clad only in her underwear—a set of pure, virginal white.
The bra cupped her small breasts that seemed to reflect the girl age, the swell of them straining against the innocent fabric. A tiny red ribbon adorned the front of her panties, a single childish detail that only served to accentuate the mature, womanly curves of her hips and thighs.
"How is it...? Does seeing me innocent body like this... make your heart beat even a little bit faster?"
She stepped closer, her hands rising to gently cup my cheeks. The warmth of her palms seared my skin as her hazel eye stare at me.
"Ah... y-yeah..."
"Fufufu... I'm so happy... Just like this... won't you please... take my first time?"
Her face drew nearer, her lips parting slightly.
"Absolutely not! You know I have a girlfriend!"
I hands shot up, gripping her bare shoulders to hold her at bay.
"Please...! Just once...! Once is all I ask...!"
Even as I pushed, Toka resisted, her voice a frantic, desperate entreaty.
"I am the only daughter of the Hojoin family. Someday, I will be made to welcome some man I do not know, a political match I cannot refuse. So... please! At the very least...! At least let my first time be with the one I love...! That is my most fervent, desperate wish...!"
Tears streamed freely down her cheeks now, her confession a raw, bleeding wound laid bare before me.
'Damn it...' I thought.
"I'll be sixteen next year. The same age my mother was when she was wed into this family."
"..."
"So please...! I'm begging you...!"
Her anguished plea hammered against the walls of my conviction.
Lost in the tempest of my indecision, the strength in my hands wavered. I felt her draw closer, her soft, trembling lips inching toward me.
"Sensei... Mm..."
Toka's eyelids fluttered shut, her face tilting up to meet his in a kiss—
*Knock knock... Clatter...*
The sound of a knock, followed instantly by the door sliding open, shattered the moment like a pane of glass. My hands tightened, shoving Toka back just as Kaoruko stepped inside, a tray laden with tea balanced in her hands.
"The tea is... ready... I..."
Kaoruko's words died in her throat. Her gaze swept over the scene—her daughter, half-naked in nothing but her pure white underthings, and the tutor frozen mid-push.
"Ah... Hmm... I see..."
A mask of icy composure slid over Kaoruko's features. She placed the tray on the table with a soft, deliberate clink before speaking again.
"Toka. For the time being, remove yourself from Hirokazu-sama's person and put your clothes back on."
"But, Mother!"
"Toka?"
"...Yes."
At the subtle, steel-laced shift in her mother's tone, Toka's defiance crumbled. She backed away and stooped to retrieve her discarded dress.
I suppressed a shiver; the quiet authority in Kaoruko's voice had been terrifying.
After a brief, tense explanation of what had transpired, Kaoruko let out a long, weary sigh and bowed her head deeply toward me.
"Sensei. I offer my deepest apologies for my daughter's utterly discourteous behavior."
"N-No! Please, raise your head. She's at that age... an interest in such matters is only natural. And... I understand Toka-chan's feelings."
I forced my voice to remain gentle, carefully choosing words that wouldn't betray my own inner turmoil.
"Sensei..." Kaoruko lifted her head, a small, enigmatic smile gracing her lips.
Then, rising to her feet, she moved toward the door and called out, her voice now carrying a sharp, carrying edge.
"Kotaro. You are there, I presume?"
'Ha! I am at your side!' A disembodied voice answered from seemingly nowhere.
"What Toka just did is not to be spoken of to anyone. Am I understood?"
'Ha!'
The easy warmth was gone from Kaoruko's voice, replaced by a chilling undercurrent of menace. I felt a fresh jolt of surprise.
"Furthermore, from this moment until I personally give the order, no one—no one—is to approach this room. That includes Genan, and it most certainly includes yourself."
'B-But, my lady! In that case, your own safety!'
"Are my words somehow unclear?"
'...! Ha! Should anyone approach within a ten-meter radius, I shall immediately turn them away!'
A visceral shiver crawled down my spine. That single, quiet question had radiated the absolute, crushing weight of a true family head. For the first time, I truly believed the rumors that the university friend had whispered were real.
"Good. You are dismissed."
'Ha!'
With that, Kaoruko slid the door shut once more. She turned back, her expression instantly softening into its usual gentle smile.
"Fufufu... Now, there will be no further interruptions."
She glided over to where a dejected Toka sat on the floor, sinking down beside her and pulling the girl into a comforting embrace.
"Mother..."
"Toka? Do you love Sensei?"
"Ah...! Yes! I love him with all my heart! Enough that I would wish to spend my entire life by his side!"
"Is that so..."
Kaoruko listened, then a satisfied, almost proud smile bloomed on her face as she stroked her daughter's hair.
Toka's confession filled me with a bittersweet ache. Her feelings were genuine, profound... but I already had someone I intended to spend my life with.
"Sensei."
"Y-Yes!"
The sound of Kaoruko's voice snapped me back to attention, my posture rigid with apprehension.
"I understand that this is an utterly presumptuous request, especially after the scene that has just occurred. However, would you be so kind as to consider granting Toka's wish?"
"Mother..."
"Kaoruko-san... But, I already have..."
I wanted to grant Toka's desperate plea. But to do so would be a betrayal of Rena. The two choices hung in my mind like weights on an impossible scale.
"I am fully aware. I know you have a woman you love. Yet... I beg you to take pity on Toka's feelings, to understand their depth..."
"Th-That's..."
Her earnest gaze sent another tremor on my resolve.
"As you heard from Toka, I was married into the Hojoin family at the tender age of sixteen. It was a match decided when I was but a child... at the time, I accepted it as simply the way of things. My late husband was a good man; I had no cause for complaint…"
"However, once I became a parent myself, I began to agonize over whether it was right to condemn my own child to that same, harsh destiny." She continued.
"Mother..."
Kaoruko spoke with a wistful smile, her fingers gently stroking Toka's hair.
"My husband agreed with my convictions, and we made it our mission to systematically dismantle every last marriage proposal that came her way. To free her from those archaic shackles, he implemented sweeping reforms. Think of it like a corporate reshuffling of personnel. Under his leadership as the sitting head at the time, a fresh wind began to blow through the Hojoin household. But... his body had always been frail. In the end, he departed this world..."
"Father..."
A flicker of grief crossed Kaoruko's features as she spoke of her late husband, and Toka, stirred by the memory of her own father, pressed into her mother's side with a forlorn expression.
Kaoruko simply pulled her closer, a soft, sad smile returning as she held her daughter tight.
...
"So that's what happened... Such a thing..."
After the talk with the Hojoin mother and daughter, I had been treated to a lavish lunch. Now, I walked toward the rendezvous point for my date with Nino, my phone pressed to my ear as I reported the day's events to Rena.
Her voice, though gentle, carried an unmistakable thread of sorrow woven through her words.
"I'm sorry! I let my emotions get the better of me! And I gave in to my own base desires... I'm pathetic, aren't I..."
"Fufufu... That compassionate heart of yours is both your greatest virtue and your most troublesome flaw. But... I love you exactly as you are, you know."
"Rena... thank you. My heart is always with you, you know that."
"Fufu... thank you. Still, to think the student you've been tutoring was the young lady of the Hojoin family... That, I confess, is what truly shocks me."
'Wait... she's more surprised by that than the fact I got swept up and had sex? Does she actually not trust me as much as I thought?'
"D-Do you... not think I'm very trustworthy?"
"Hm? Ah, no, that's not it at all. It's just... considering you're already involved with my daughters, it isn't that much of a shock, I suppose... Well, the matter of my daughters was something I myself asked of you, but... um... Are you truly telling me you had no experience with women before we met?"
"Eh!? N-No, I didn't! Not that it's something to boast about..."
I scrambled to answer Rena's pointed question, but a wave of self-deprecation washed over my regardless.
"Hmm... All the girls around you before must have simply lacked discernment. But, thanks to that, I was able to become your first woman, wasn't I? It makes me so happy."
"I feel the same way. I'm glad, from the bottom of my heart, that my first time was with you, Rena."
"Dear... Honestly! Saying things like that when I can't just rush over to see you right now!"
"I feel the same. I want to see you too, to hold you tight in my arms."
Hearing her confess her desire to meet, I let my own matching feelings spill out freely.
"Fufufu... Let's meet tomorrow, then. Something you said about today has sparked an idea in my mind, and I'd like to discuss it with you."
"An idea?"
"Yes... I may end up using you, in a way. And... you might come to hate me for it."
Rena spoke of an idea, but warned me that it might lead to me despising her.
"Tch... Don't worry about that. I'd do anything for you, Rena. This idea... It's for the sake of our future together, isn't it?"
"Dear... thank you."
A voice laden with relief and joy answered my declaration. 'God, I really want to see her right now and just hold her close...'
"So, for today, don't fret over what happened. Focus entirely on making sure Nino has a wonderful time."
"Understood."
Just then, I arrived at the meeting spot. Nino didn't seem to have appeared yet.
"Even so... you are an honest man. What happened today... You could have easily kept silent about it. With the Hojoin family's influence, it would never have leaked out."
"I could never do that. The thought of keeping secrets from you... that would hurt me far more than you hating me for it."
"Fufufu... Is that so? To be cherished so deeply... I must be the happiest woman alive. Well then, I'll hang up now. I love you, Dear."
"I love you too, Rena."
The call ended. I had steeled myself for the possibility of her disgust, for talk of separation. 'Thank god... Sigh... I still really want to see Rena, though...'
"Nii!"
Lost in thought, staring up at the sky, I was roused by Nino's bright voice. She approached me with a beaming smile.
"Sorry, did I keep you waiting too long?"
"No, not really. I just got here myself."
"Fufu... I've always dreamed of having that kind of exchange, you know... Doesn't it feel like we're real lovers?"
"Now that you mention it, it kind of does."
I chuckled as I replied to Nino, who seemed positively giddy. Today, she wore a black inner top beneath a thin white blouse, paired with a black mini-skirt.
"Whoa... You look really mature today, Nino. Though I think that skirt might be a little too mini..."
"Fufufu... thanks. But isn't a skirt like this perfectly normal?"
"No, I mean... I just don't really like the thought of other guys looking at you..."
"Fufufu... so you're the jealous type, huh?"
Visibly delighted by my words, Nino snaked her arm around me, linking them together.
"Of course I am. If you're not careful, someone could even see up that thing."
"It's fine. I'm careful about that kind of thing. But you being jealous... makes me so happy."
Having linked her arm with me, Nino pressed herself even closer, deliberately mashing her small breasts against my stomach.
"Your chest is pressing against me, you know."
"I know. I'm doing it on purpose."
"Thought so. So, what do you want to do? Hit up a mall, do a little shopping?"
I sighed at her brazenness but played along, asking about their plans for the day.
"That sounds nice, but... how about we just go to a hotel right away?"
"Huh!? So suddenly!?"
"I mean, if we wander around here, one of my sisters might spot us, right?"
"Well, yeah... that's true. But, we don't have a reservation anywhere, do we?"
"Don't worry, I already looked into that."
Startled by her abrupt suggestion of heading straight to a hotel, I couldn't deny the risk of being seen by one of the other quintuplets.
When I asked which hotel, Nino was already pulling out her phone, having apparently done her research in advance.
"How about this place? Doesn't it look nice?"
"Huh? Wha—! That's a love hotel!"
"Oh? My friends use places like this, too, apparently. And I'm a little curious myself."
'Seriously... high school girls these days are way too forward...'
"Well, alright. Today, I'm yours. We'll go wherever you want, Nino."
"Thank you. It's a little far, so let's take the train."
And so, under Nino's direction, we made our way toward their destination.
"Huh... So this is what it's like inside one of these places. It's actually pretty stylish, isn't it?"
"Yeah. It's my first time in one, but the vibe is nice. Whoa! The bathroom's huge..."
I agreed with Nino's assessment, my eyes twitching at the sheer size of the bathing area.
"Wait, this is your first time, nii? I figured you'd have been to one with Mom already."
Nino's expression flickered with genuine surprise at my admission of being a love hotel virgin.
"It's not like we can just casually meet up outside, right? We mostly use my apartment. Here, give me your blouse. I'll hang it up."
After hanging my own jacket on a hanger, I reached out to take her blouse.
"Huh~... So I get to be one of your firsts in this kind of place, then. Fufu... that makes me happy."
Once her blouse was safely on a hanger, Nino pressed herself against me in a joyful embrace, her arms wrapping around my torso.
"Hm? Sniff sniff...nii, did you start wearing cologne or something?"
"No, I don't use any. Why?"
"It's just... there's this really nice scent on you, I think..."
She pressed her nose into my chest, inhaling deeply as she voiced her question.
'Shit...! The fragrance from Kaoruko-san's incense must have clung to me...!
"I was at my tutoring job just before this, remember? The mother of the student there is really into incense, and she offered me some. Maybe that's what you're smelling."
"Hmm-... I don't think it really suits you, though."
"That's what I thought too, so I turned it down. Still, maybe I should look into getting some proper men's cologne after all...?"
I deftly steered the conversation, posing the question to Nino as a diversion.
"Hmm... I like nii's natural scent just fine, but wearing a little something as a fashion accent might be nice, I suppose."
"Yeah? Well then, how about you come with me to pick something out sometime?
You're way better at that kind of thing than I am, right?"
Relieved at having successfully deflected the topic, I made the suggestion, a silent sigh escaping within my mind.
"Sounds good. Fufu... I'm already happy just having locked down another date with you, Nii."
Her mood soaring, Nino pressed herself even closer, her eyes fluttering shut as she offered her lips to me. I leaned in and captured them in a kiss.
"Sllurp!! From now until tomorrow morning, I've got Nii all to myself, Slurp."
As the series of pecking kisses continued, Nino's good mood intensified. She extended her tongue and traced it along my lips. I met it with my own, our tongues entwining.
"Slurp Slurp ... Haah... Slurp! Ahhh"
Even as they kissed, my hand slid down and slipped beneath the hem of her mini-skirt, cupping the firm swell of her ass.
"Hm? Nino, you are wearing panties, right?"
"Ahhh Nn... Of course I am... Nn..."
"Feels pretty...free for that... Wait, don't tell me..."
As my hand roamed over her rear, my fingers traced closer to the crevice. I could definitely feel the texture of the fabric. But this sensation...
"Nino... just a wild guess, but..."
"Fufu... I told you, didn't I? I'm wearing my battle panties today."
With that, Nino pulled away from me. She stripped off her inner top and unzipped her mini-skirt, letting both fall away.
Revealed beneath was a set of delicate, light-purple lace lingerie a bra of intricate lace and a thong made of the same sheer material, the fabric barely there. And more than that-
"A string thong!? How did you wear something like that under that tiny skirt!?"
"Fufufu... Well? Does it turn you on?"
Ignoring my outburst, Nino struck a deliberately seductive pose, her body language dripping with provocation.
Gulp...
The sight of her like that made me swallow hard. I advanced toward her without a word.
"Eh? Nii...?"
Silent, I scooped her up and laid her down on the bed. I shed my shirt and pants with swift, efficient movements before climbing over her, my body caging hers beneath me.
"You lit this fire, Nino. You're going to take full responsibility for it."
"Eh... Nnmu... Slurp! Slurp Slurp Ahhh Ahhh."
I sealed her lips in a deep, tongue-twining kiss. Even as my tongue explored her mouth, my hand found her breast, kneading the soft flesh through the thin lace of her bra.
"W-Wait...Niii... Ahhh Ann... Right there..."
Breaking the kiss, I shifted my attention. I took her earlobe between my teeth, nibbling gently before sliding my tongue into the delicate shell of her ear, tracing its contours. My hand never ceased its assault on her small breast.
"Nnno... That spot... it's sensitive..."
"Hoh-... That's good information to have."
While Nino was lost in the sensations assaulting her ear, my other hand worked behind her back. With a practiced flick, the clasp of her bra sprang open.
I peeled the lacy cups away from her breasts, discarding the garment.
"Ahhh, so good... Ahhh Eh... No way... Nn... When did you...?"
Even as she registered, through a haze of pleasure, that her bra was somehow gone, the relentless sensations overpowered any coherent protest.
Sweet, breathy moans continued to spill from her lips.
I pinched and rolled her now-exposed nipple between my fingers, continuing my ministrations to her breast. At the same time, my tongue traced a wet path from her ear down to the sensitive nape of her neck, leaving a trail of fire in its wake.
"Nn... Can't... Haaahaan..."
"Fufu... Your nipples are so hard, Nino. They're getting so stiff..."
My lips and tongue continued their journey, trailing from the nape of her neck down to her collarbone, placing open-mouthed kisses along the way.
All the while, my fingers teased her nipple, lightly pinching it one moment, then rolling the pebbled peak in gentle circles the next.
"Hyaa... No way... no, no, no... I'm cummiinnnggg..."
Nino's body convulsed in a small climax, her hips bucking upward as tremors wracked her frame.
I paid the orgasm no mind, my relentless attention unbroken. I lowered my mouth and finally took the aching, rigid peak of her nipple between my lips.
"Nnaa...! No, don't... I just came... so I can't... Nnn..."
As if deliberately ignoring her pleas, I sealed my mouth around her nipple and sucked hard, my tongue swirling in maddening circles around the sensitive bud.
"Nooo aaaahhh...! Stop... That... don't do thaaat... Ahhh Ahhhhhhaaannn..."
A second climax ripped through her, leaving Nino gasping and breathless.
"Haah... Haah... Haah..."
While she panted, struggling to catch her breath, I kept her spent nipple in my mouth, sucking gently. My hand, meanwhile, trailed down her stomach and found the delicate string ties of her thong, tugging at them.
"Wait... No more... it's impossibllle... Nnn... It feels so good... I'm going crazzyyyy..."
Utterly lost to the overwhelming pleasure, Nino didn't even register the loosening of her panties.
I coaxed a third orgasm from her quivering body before finally releasing her nipple from my mouth with a soft, wet pop.
Shifting down the bed, I positioned my face before the junction of her thighs.
"Haah... Haah... Haah...Niii... you're... too amazing..."
"Hmm... You really are meticulous, Nino. Your pubic hair is starting to grow, so neat and tidy."
"Haah... Haah... Huh...?"
Her mind still clouded with pleasure, Nino couldn't process my words. She just gazed down at me, her expression dazed.
"...No way! When did you-!? Wait...! Don't look...!"
A wave of mortified realization crashed over her, and her hands flew down to cover her exposed sex. But I caught her wrists, pinning them gently to the bed.
I leaned in and dragged my flat along the slick, glistening lips of her pussy.
"AAhhh, what... is this... It's completely different... from fingers..."
Her will to resist utterly shattered by the novel sensation, Nino's arms went limp, sinking onto the bed.
Taking full advantage, I used both hands to spread her folds open wide, exposing the delicate, pink entrance of her cunt. I thrust my tongue inside.
"Ahhh Ann... No way... Nii is... licking my pussy... I want to hate it... but it feels too good..."
"Let go, Nino. Let it feel good. Just keep feeling better and better..."
"Ha... Ahhh Ann... What is this... I didn't know it could feel this good... Ha... Ann."
After thoroughly lapping at her inner walls, I slid a finger inside her slick, clenching cunt.
Curling it upward, I found her sweet spot and applied firm pressure. At the same time, I closed my lips around the swollen, erect bud of her clitoris, sucking it into my mouth.
"Ahhh Aaaahhhh!! Aaaannn! That... you can't do thattttt..."
Pssshhaaaaa...
Nino let out the loudest moan of the day, lifted her hips, and came....
