Chapter 2: Menage a Trois

10 May (Wednesday) 4pm

Nakano Residence

"Come in, Fuutarou," her voice buzzed through the intercom as he pushed the button to announce his arrival. Miku had requested for extra lessons that day, and while it was rather uncharacteristic of her to ask for a private session, who was he to deny her enthusiasm for learning?

She's probably a little shy to seek assistance in front of her sisters, he mused, remembering the time just months ago when she had challenged him to a history test, unconvinced of her need for a tutor and preferring to study at her own pace. That said, people change, sometimes in strange and astonishing ways, just like how the toughest nut to crack had been Nino, and yet it was just over the weekend that he had tasted her soft, warm core beneath her hard shell–

Argh, why can't I stop thinking about her moaning and playing with herself, her moist, pink lips riding on my face, her warm, soapy feet sliding on my–

Miku. Only Miku. No, don't fantasise about her too! Get your mind out of the gutter and focus on helping her prepare for the university entrance exams. That's what you're here to do.

"You alright?" she asked, concerned, turning red as she averted her gaze, "You've been staring at me for a while now."

It's not like I've been intimate with your sister, who happens to look almost exactly like you.

"Sorry," he muttered, realising that he had been standing at the doorway for a good half a minute. "It's nothing, really."

God, this is so awkward. Damn the dog collar and the cookies. I know I'm a hypocrite for saying this after enjoying the experience more than I should, but perhaps it was a mistake to go for the homerun with one of them when I've yet to respond to their feelings.

"We can do it in my room," she suggested, interrupting his thoughts as he stumbled towards his usual seat at the table. "Everyone else is out shopping, they'll only be back after dinner."

"If you don't mind," he breathed, somehow a little nervous despite having not only slept on her bed but beside her when she had mistakenly returned after a late-night toilet break during the sleepover last year. Unexpected as it was, she had confessed to him in April, shortly after the new school term began, and he could not help but feel some nagging guilt and shame as he ascended the stairs, glancing briefly at her elder sister's door before stepping into her room.

Wow, it's so neat and tidy, he remarked, only to pause when he saw her blush like a tomato.

"I-I mean it was already in good shape before, but now it's sparkling," he hurriedly clarified as she glowed an even brighter shade of pink, "and no, I wasn't trying to remind you of that time–"

"Apologise," she pouted, pointing at the floor, and he instinctively shuddered amidst a creeping sense of déjà vu. Nonetheless, with an anxious gulp, he cast his bag aside and made himself comfortable as she sat on the bed and crossed her legs, her delicate toes poking at his cheek–

Wait, what?

"L-Lick me and say you're sorry," she stammered, looking away in embarrassment as she thrusted her foot forward, "Don't worry, it's a new pair of tights, I-I've just cleaned and mopped the room too."

"Is that why you went home right after school?" was all he could manage as he gaped at her, equally surprised and confounded by her bold yet bashful actions.

"Nino told me you liked being treated like this," she spluttered, stumbling over her words, not that he would have ever expected them in the first place. "I-Is that true?"

Since when? And what happened to keeping our encounter a secret? Did she really have to rub it in her sister's face?

"Do you?" she pressed on, as if his reply mattered beyond mere curiosity.

"No, I mean, not really."

"T-Then what do you like?"

"Studying?" he deflected, eliciting a disapproving frown and a soft kick to the side.

What's with this atmosphere, she's unusually determined!

"Enough of playing around," he tried again, pulling her feet away, "let's get back to class for today, okay? We've got a few topics to cover–"

He was cut short by a sniffle, followed by a sob that was painful to hear.

"I-I can't believe that I waited so long and tried so hard," she cried, "a-and she just made you hers because you ate some of her biscuits. I-I know I'm bad at cooking and pretty much everything else, but I-I don't deserve this."

In the deafening silence, he kept his head low. With or without the boost to his libido, he had no one to blame but himself for acting out his desires and sleeping with her sister. Of course, Nino could have been more discreet with their escapade, but whether she would come to know or not, it would be a betrayal of her feelings all the same.

And his too - for he did have more than a soft spot for her, and would have been happy to reciprocate, if he had known earlier, and had more time to consider–

But would he have chosen differently? Would he have rejected Nino? Would he have cruelly ignored her and left her cold and disappointed and alone on that fateful night?

Was it even fair for him to think this way when he had taken her first?

At some point, he had begun to go around in circles, but one thing was clear - he liked them both and would never want to hurt either of the sisters.

"I-I don't care anymore," she wiped her tears with the sleeve of her cardigan, glaring at him with renewed resolve. "She may be the first, but I-I'll be better."

"Miku, what–" he stuttered as she reached under her skirt and removed her tights, exposing her slim legs and slender thighs. Before he could stop her, she had pulled off her underwear, revealing pink folds between shaven lips which were glistening with anticipation.

Words were stuck in his throat as he noticed the scratch marks around her carnal regions - the unmistakable injuries from a razor blade in her anxious and inexperienced hands. That was how serious and determined she was in preparing herself for the moment, and he truly could not find it in him to deny her after all her unrequited efforts.

He just needed to be sure, even if the proof was before his very eyes.

"I like you, Miku, as much I like your sister," he gritted his teeth and confessed, seeing no point in concealing his feelings any longer. "You probably think I'm the lowest of the low for saying this, but it's the truth, and my only hope is that we can be more open with ourselves and each other. I want to know what you like and what you don't - and if this is what you really want, then I would be more than glad to–"

"Fuutarou," she smiled from the bottom of her heart, "just be gentle."

Nodding, he decided to start with his tongue. She tensed as he made contact, unused to the sensation, but soon settled into the rhythm, immersing herself in the stimulating moisture. The mixture of his saliva and her wetness felt like honey on her wounds, causing her to moan helplessly through the hand she had clamped over her mouth. Before long, she was beginning to lose herself to the rising tides, and he stopped her fingers from gliding downwards, curbing her impatience to tease her to greater heights.

Unable to satisfy herself, she had nowhere to go but back up, and as she began to shudder and drool at his ministrations, so near yet so far from the much-awaited peak, she could only unbutton her shirt and grope her twin mounds to reach a higher plane. Her mind seemed to swirl in the clouds, perspiration condensing on every pore like rain, yet there was still some distance to the top, even as her perky tips have never been harder in the cold.

As he maintained his pace, a part of her wanted it to last forever, addicted to the wild excitement of teetering on the edge, a step away from the fatal plunge. Her cheeks flushed at the thought of him giving her the final push, only for him to slow to a halt as she gasped and panted, nearly driven mad by her desire for more.

"Take me," she heaved as he hesitated, "you can't just stop now and leave me hanging."

"Miku, give me five minutes, I'll run to the convenience store to get some–"

"I'm safe this time of the month," she assured, crawling off the sheets and onto her knees, "I know my sister probably got you to wear one, but I-I really want you to go all the way, Fuutarou."

"Please," she begged as she tugged on his pants and took his throbbing stick in her mouth. While inexperienced, she had watched a few videos to brush up her skills, making him swell on her tongue as she slowly and sensually stroked his shaft. Validated by his contented grunts, her initial nervousness and apprehension gradually dissolved, allowing her to indulge in the sweet, warm liquid dripping from her lips above her chin and below her navel without a care for the world. But as much as she enjoyed the humiliation and the degradation, she made sure to stop before he could finish, wanting him to fill her in the other mouth, even as he tried to sneak one last shove between her cheeks to ease himself off.

Shaking her head, she lay on her back, spreading her thighs to show him the true end that she craved for. He obliged, and she almost wept in relief and agony as he entered her, the length of his spear piercing her barriers to explore the depths that she did not know she had. Blood trickled as he disengaged himself to dab her dry with a towel, letting her rest and catch her breath until she was back in the mood. Caressing her bud made her moist again, and he connected with her once more, parting her pink folds and inviting walls, causing her to inhale deeply, her heartbeat racing with the thrusts from the rod that was hard as wood.

He's finally inside me, she beamed, drowning in the waves of forbidden pleasure surging through her spine. She loved how he alternated between gripping her knees and squeezing her ankles, drawing circles on her soles and biting down on her toes, all the while smashing her between the legs, sending her soaring beyond the mountains and flying towards the moon. She could feel the rush of adrenaline coursing through her veins, the exhilaration burning in her loins as she burst through the atmosphere, the hairs on her skin standing on their ends as paroxysms of electricity radiated across her body, the accelerating build-up in static charge desperate for an avenue to blow up and explode on–

"Miku," he groaned, unable to hold himself any longer, "I-I'll have to pull out."

Seconds away from euphoria, she tightened around him, unwilling to let go, yet he managed to break free, finishing over her tummy as she grappled with her own ruined climax, spiralling from the sky like a lead balloon that had flown too close to the sun. At this, she nearly tore her hair out in her frustration, and as he proceeded to clean up his own mess as if nothing had happened, the biggest pout etched itself on the face of the scorned young woman.

"Lick," she ordered, prodding a finger at his nose to direct his attention back at the area aching for release. Confused, he stared dumbly at her, bringing a hand to aid in his task, which she mercilessly slapped away before coiling her legs around the back of his head to keep him in place until she was in a mood to forgive.

Mm. Ah. Hah. Yes.

Somehow, she enjoyed being in charge for a change, digging her hands into his hair as he mumbled his apology into her lips. Trapped between her thighs, he attended to her more passionately than ever, sucking and nibbling until she was back on the hill, scaling new highs. By the time she collapsed on the pillow, her nails digging deep into the mattress, she was drenched in sweat, growling a noise that sounded more animal than man.

Recomposing herself, she tempted him to enter her mouth, goading him to relieve himself, which he was smart not to fall for. Undeterred, she kept up the momentum, her lips sliding over his erect stick, sucking with just the right force, intent on making him spill, yet even as she pumped him between her moist cheeks, he remained tough and unyielding to the end. It was only after more labouring that she managed to coax some fluid out of him, and as he closed his eyes, ready to claim his delayed reward, a mischievous grin spread across her face, and she grinded to a halt, leaving him cold and dry as she teased him with her soft tongue, revelling in the abrupt denial that she had intended for him to feel.

Resisting the urge to get himself off, he kept himself calm as she folded her arms and waited for a reaction that mirrored her own, only to grumble in annoyance as he remained cool like a cucumber and hard like a rock. He nearly laughed as she imploded under his glare and started to touch herself at the sight of his throbbing member, undoubtedly imagining him doing the same to her, and he graciously offered his support, ending the standoff in a reconstruction plan which she was thrilled to accept.

Assuming a position of truce and harmony, she stroked him over her chest as he brought her to heaven with his fingers between her dripping wet lips. Still shivering from the aftershocks, she invited him to join her in the bath and pound her senseless in the shower, letting him spray on her rear and watch the soap and foam roll down her thighs before washing them off with water. By the time they were done, they were famished and fatigued, and together, they dragged their limp feet and sore hips to the nearby convenience store, not for anything else but instant ramen, which she could easily cook for them.

"That wasn't quite what I was expecting for my first," she giggled as she slurped down her noodles.

"You really let yourself go," he chuckled, taking a long sip of his MAXX coffee, "I'm happy that you embraced and expressed yourself in that precious moment that we shared."

"I-I guess it's easier to do so when a-aroused," she blushed, reverting to her usual shy persona. "Now that I've tried it, I-I don't mind being in the driver's seat, b-but I'd still prefer if you took the lead."

"If that's what you want," he patted her head, ruffling her locks. "Maybe after we're done with today's lesson."

"There's always next time, right?" she smirked as he pinched her cheeks playfully. With that, she put away her food and took out her books, telling herself to focus even as her mind inevitably drifted back to the events that had just taken place.

I'll study hard to make us proud, Fuutarou. Even if we may not end up in the same place, I'll always remember where it all began.

A/N: Miku joins the race with some tsun to complement her usual dere (mirroring Nino's M amidst her general S in chapter 1). In canon, Nino gave Uesugi scented candles for his birthday (to 'sleep better') while Miku gave him a gym membership (to 'get stronger'), so take from it what you will, heh.

In terms of analogies, Nino was holding back a hurricane in the stormy sea while Miku was trying to climb a mountain to reach the sky - a reference to their respective Summer Vacation choices in Chapter 90 of the manga (Quintuplets Flashback arc).

As always, favs/follows/reviews highly appreciated!
