They put a label on their relationship, and yet they were more to each other.
It all started rather innocently. At least, as innocently one situation could lead to a lewd and naughty outcome.
It stemmed from the simple principle of offer and demand, each party desiring something, and the other happened to be able to provide it.
Those were the circumstances that brought Tachibana Hibiki and Yukine Chris together in the way that they were unaccustomed to one another.
The core factor responsible for their first meeting was a lesbian brothel service in which they respectively involved themselves at one point.
How the two were involved respectively was another main, common denominator, sexual urge.
For Chris, it was a dry spell going on for too long after the parting of her savior, mistress, and lover Finé, as well as settling into her new life as a Lydian student. While getting off and reaching a climax on her own wasn't difficult, the ordeal was doing little to sate her when she has been accustomed to the contact of another body against her own. She soon was enlisting herself into the business after being a patron for a few weeks and touring all the available partners.
As for Hibiki, it was a mix of several issues coalescing into something burdening at odd times. The circumstance of her body's oddity and puberty hit her harder, leading to the path of self-pleasure and masturbating initially, then a growing anxiety and lack of self-confidence over the extra appendage her body was bestowed and the prospect of finding a partner willing to accept her all.
She later realized that accepting herself should come first, then building her confidence. It led Hibiki to work up the courage to lose her virginity for starter, seeking the service of a lesbian brothel. After browsing through the selection of girls available, she picked one that would seemingly be open-minded about her condition given her profile's content.
In retrospect, she should have picked up on the silver-white hair in the profile picture, as it was not quite the common hair color, but she didn't. It certainly would have made her reconsider going through the booking of the girl named 'Snow' if she did.
Surprise was their mutual reaction when spotting one another, bewilderment that both were waiting for someone to appear, and finally shock when realizing that they were each other's date.
Canceling would have been the most sensible thing to do, to never speak of the event and go on with their lives as if nothing happened. And Hibiki was willing to do so, already sufficiently embarrassed over the situation, yet Chris had other plans in mind.
With the promise of not making fun of her and snacks, Hibiki found herself spilling her guts over her predicament, laying out every bit of insecurity about herself to her barely known friend and freshly enrolled senpai at the time.
It was freeing in more ways than one, a part of the weight on her shoulders being lifted.
And while she didn't expect much Chris would say, she even less expected the invitation to go with the initial reason for their rendezvous.
Hibiki took Chris on the offer after listening to her reasoning. Mainly taking her head off her immediate troubles in exchange for a good time. And also, as to not make Hibiki's efforts toward losing her virginity end up for naught.
And a good time it was, Chris was both experienced and patient with her, barely batting an eye when she discovered the girthy cock hidden underneath her skirt aside from a comment regarding how big it was.
Putting it simply, Chris made it her mission that Hibiki losing her virginity was an experience to be remembered and cherished while getting herself good during it.
And Hibiki had no doubt that Chris did, the way her senpai seemed to have savored every moment of their intercourse, hitting a trifecta in servicing the girthy shaft with her hands, boobs, and even butt cheeks, then adding her mouth and pussy by the end for a complete experience for Hibiki's first time.
Hibiki was surprised how she was able to keep up with Chris' sexual appetite and stamina, participating with returned passion until the two were worn out and nothing but twitching mess against each other.
With a silent promise of doing it again hanging in the air between them.
It would turn out that Hibiki was quite the innocent girl at heart, and once the high of the event had come down, the need to face the music as if nothing big happened was difficult for her.
She was awkwardly behaving around her smaller senpai, what they did that day heavily weighed on her mind, plaguing her daily and making her randomly combust a shade of red she would be ashamed to explain how and why she was blushing.
Thankfully, Chris was there for her, albeit not without poking much fun at her expense, but she nonetheless, succeed in easing her mind so as not to be too obvious to others, at least.
Chris would confidently confess to Hibiki that she had been looking forward to getting laid that day and that hooking up with a friend wasn't a strong enough deterrent to impede her objective.
Later on, Hibiki would make a second booking for Chris. It would then become a third, turning into a fourth, a fifth, until Chris quickly realized that her booking history has essentially been with one girl, repeatedly.
She addressed the matter with her kouhai, and one heartfelt talk later, Chris was off the service list, no longer bookable to other patrons, to then never be seen frequenting the lesbian brothel again, leaving with rumors she found herself a lover or something.
It was not entirely false, Hibiki and Chris had become exclusive sex partners from there onward, friends with benefits, allowing them to hook up as much as their bodies would desire, free of charge and without a time limit.
A physical relationship aimed to satisfy each other lust, one that would naturally stop when either of them enters a romantic relationship.
At least, that's what they thought then… in a way.
Afternoon
Chris' Apartment – Living Room
"Thank for letting me use your shower, Chris," Hibiki says, stepping into the living room and joining her senpai on the couch, the latter's eyes focused on their phone.
Seeing that her senpai was not paying her any attention, Hibiki sprang into action to remedy to it. Leaning closer to the other girl, Hibiki took hold of the distracting device, tossing it away on the couch.
"You don't need this when I'm here," She coos into Chris' ear as she embraces her, pecking her cheek while shifting her legs for her partner to be seated between them, then dragging her with her and lay down the length of the couch with her senpai weighting comfortably against her.
Hibiki then rests her chin on Chris' shoulder, the two teenagers releasing a content sigh being in each other's presence and intimate contact.
These kinds of moments have been why the original line between purely sexual relationships, and more was blurred.
Since Chris' apartment has become their main location for their hookups, it slowly bled into them that, contrary to a love hotel with a set time limit, they could do something else unrelated to sex afterward.
Hibiki staying after the deed wouldn't be odd for either of them, taking the time to rest, lazing around, or just getting cozy with each other. It was something to even look forward to.
Weeks would go by as Hibiki would spend more and more time at Chris' place, doing what was to their own guess, getting help with homework would be the go-to excuse to their friends, and while Hibiki's homework would indeed be done by the time she leaves, at least one round between the sheets would occur at one point.
It was another home away from home for Hibiki, one where she would always be welcome, moreover so when none of Chris' upset expression would remain long enough upon realizing it was Hibiki entering her place, their place.
Cooking, cleaning, even laundry, Hibiki would pinch in any housework with pleasure, progressively leaving her mark and proof of her presence here.
Hibiki couldn't help the smile tugging at her lips, seeing the friend she gradually started to refer more and more intimately as her lover was donning one of her oversized shirts, her prominent was bulging the item, but the length remained long enough to go past her hips and below her rear, barely revealing the underwear underneath.
She rained kisses on her lover's cheek and neck, coaxing pleasurable purrs from her that made butterflies flutter in her stomach and reaffirming her embrace around the silver-haired beauty.
She was in love.
Hibiki didn't know when exactly, but at one point she was no longer seeing Chris as just a friend to have sex with or hanging out, she was yearning for more, more than what their status of friends with benefits was providing.
Or at least, what this status should provide, and she was blaming Chris for everything.
If those seductive, amethyst eyes hadn't been charming her like they were currently doing. Those plump lips molding to her own in tender and melting kiss with dancing tongue.
If Chris hadn't been so good to her, worming in each corner of her heart by being so kind to her, she wouldn't have nurtured such deep-rooted feelings for her senpai.
She has thought about confessing numerous times, elevating their relationship to a more official term, but she would backtrack again and again at the last moment, the potential lost being far bigger than what there is to win.
However, Chris was torturing her by accommodating her with her behavior, but nothing to seemingly hint that she wanted more on her part. And for all Hibiki knew, Chris might have been accommodating her actions because she discovered the kouhai had feelings for her but still wanted to maintain their relationship regardless.
Yet this latest thought would make less and less sense.
Especially with how Chris is craning her head toward her, a hand cupping her cheek before erasing the small space between their lips.
Hibiki believes that there was no way someone could kiss this way, breathing in sync, moaning, willingly entangling their tongue, and swapping saliva, without them feeling remotely more than friendly thoughts in their head.
That's how Chris can, and would kiss her, and this without much lust behind it. It might as well be considered as a greeting or a simple thank you.
They were practically acting like lovers without the proper label. And Hibiki was starting to think that she was making a big deal of something not that important when everything was so good.
Quieting this line of thought for the umpteenth time, Hibiki focus on returning the kiss with as much of her love for her senpai in it, as she has been doing since realizing her feelings.
They part with shimmering lines of spit bridging their lips, looking at each other with now lust-glassed eyes, pecking each other lips a few times before settling back against each other.
Hibiki made a conscious effort of ignoring her penis coming to life, her erection undoubtedly pressing against her lover's back, yet seemingly not acknowledged by the latter.
Hibiki felt the hand cupping her face withdraw, joining hers around Chris' frame, fingers interlacing then brought on her senpai's stomach, a last peck gracing her chin before settling herself back cozily against her shoulder with a gentle sigh.
It felt good, right, she was complete and almost nothing was amiss. And Hibiki was unwilling to break the silence this soon.
"Shishō was wondering how you wanted us to proceed for your birthday." Hibiki broached an important subject.
"What did he have in mind?"
"He wanted to combine it with the S.O.N.G party. Though, it leaves the choice of the date, the 25th, Christmas, or the 28th, your birthday."
Chris lay there contemplating the situation. She recalled last year's commotion over not sharing the date of her birthday, the upset entourage, their attempt to make up for it, and the promise to do better this year.
To be fair, Chris really didn't mind not celebrating her birthday, or at least celebrating quietly. But she also was aware that her friends didn't share the same opinion on this, especially one who was adamant that each birthday is, and must be celebrated.
She let out a sigh, rolling her whole body against her kouhai to face her, pressing her front against Hibiki's.
"I honestly don't care much," Chris says to her before kissing her lips, preventing the kouhai's retort at the tip of her yearning tongue. "For all I care, I wouldn't mind spending my birthday quietly," she follows before laying her head against Hibiki's collarbone.
Hibiki had a visible pout on her face, and even if her lover couldn't see it from her angle, she made sure to share her thoughts on the matter. "Come on, Chris. At least let me do something big for you."
Chris couldn't help but smile at Hibiki's words as something quite sizeable was currently poking against her stomach.
She sat upright to look at her partner, shifting her legs to sit astride, her groin pressing against Hibiki's growing hard-on.
"I appreciate the thought, Hibiki. But as far as I am concerned, you already have this 'something big' for me right here." Chris' words are followed by a seductive buck of her hips, grinding herself against her kouhai's bulging cock in her shorts.
It earns the senpai a delicious groan of pleasure from the girl underneath her, and she leans closer to her. "And lucky me, I don't have to wait for my birthday to enjoy it."
Cupping Hibiki's face with both hands, she closed the distance to rekindle the euphoric feelings of lips meeting another, tilting her head slightly to mesh them more and deepening their liplock.
Hibiki could never tire of kissing her crush, following Chris' intent and returning it twofold, parting her lips to welcome slimy organ in, meeting it with her own as spit was periodically being transferred, mixed, and swallowed.
Breathing as one into the kiss turned into making out, Hibiki felt the pressure on her penis alleviated, Chris having shifted her weight from her pelvis onto her thighs.
Her lover's intention came to light when a hand was shoved inside her shorts to fish her dick out, pumping its length up and down slowly.
Their sync was broken as Hibiki let out a moan, Chris laying kisses across the length of her jaw and all over her neck while making her way down across her body.
Sooner than later, she was facing the towering rod, her mouth watering to the sight, and licking her lips in earnest anticipation.
In the next moment, the bulbous tip was taken between luscious lips, sucked as tongue was playing with the portion of the cock inside her mouth, playing with the urethra opening as precum dribbled on the prehensile organ.
Hibiki moans, and Chris purrs delightfully at the sound coerced by her lover and the delectable piece of girlmeat she was feasting on.
The glans was quickly growing too little to content herself with, her lips spreading and descending to take more and more, engulfing inch after inch of Hibiki's futahood without pause.
A powerless drawn-out groan escaped the kouhai's lips as her lover was steadily taking more of her sausage, halting for a moment at the back of Chris' throat, then slithering further in, down her convulsing esophagus, tightening all the way in until the full length of her shaft was deepthroathed.
Hibiki's back arches when Chris' gargling moans were creating vibrations all over her swallowed member, sending waves of pleasure throughout her body. That was how good Chris was blowing her, rendering her powerless in a matter of seconds.
Chris remained there quite motionless, the inside of her mouth and gullet the only area affecting both teenagers in this limbo of torturous pleasure.
Then, the pressure around Hibiki's prick was increased, Chris sucking her harder while at the time pulling out, freeing centimeter after slow centimeter of Hibiki's meat, a lewd popping sound echoing upon the release of the head.
"Fuck, I want it inside me already." She says after swallowing the delicious sample of precum.
Chris' words were followed by the girl herself springing into action, pulling her moist panties to the side to expose her drenched petals, lifting herself up, and guiding the cock to her pussy lips.
With little effort, the tip slip inside her wetly, a shaky moan filtering from her lips, before she allows gravity to assist her, dropping down and taking the full mast of her partner's cock inside her cunt, walls willingly stretching apart to welcome the thickest and longest penis into its righteous place.
Two sets of wanton moans echo loudly in the living room, Hibiki bottoming inside her senpai, and Chris taking in all her kouhai has to offer, biting her lips as she was sent over the edge into a mild orgasm.
She falls onto Hibiki, the latter catching her before hugging her tightly, her hips bucking sporadically as she embraces her, laying a kiss on her temple.
They become one once more, an inevitable scenario when the two are involved and alone. It was never of matter of if with them, only when and for how long.
Chris quickly came by after her climax, claiming Hibiki's lips for an umpteenth kiss as she started rolling her hips, massaging the delicious intrusion with her velvety tight inside, the head smooching the entrance of her womb when at the right angle.
She loves how big Hibiki was and how she could fill her up all the way through and more, forcing her body to submit to her cock under the right conditions.
Hibiki progressively took control, bucking her hips and thrusting in and out of her lover's twat, letting her body chase after its own peak while providing her lover with the pleasure she deserved on the way.
Chris interrupted the kiss to voice her desires. "Right there, Hibiki. Ohhh~ Deeper, fuck my womb!"
"You are so tight, Chris!" Hibiki voices in turn.
Their position was suddenly reversed, Chris finding herself laying on her back, Hibiki's weight temporarily on her before disappearing, her body being pulled until she was bouncing on her lover's lap.
The inside of her cunt was getting churned with how good she was plowed by the stirring tool going to town on her, her head throbbing with dizzying sparks of bliss drowning her senses and making her quiver in bliss.
Hibiki was assisting her with one hand on her butt and the other on her hips, lifting and dropping her on her cock scrapping her insides, sawing in and out with mind blogging effect.
The next orgasm was making itself known to Chris, her core knotting on itself with its upcoming release.
"Close, Hibiki. I'm close," she warns, her arms embracing her partner's neck, legs crossing as well to keep her close.
"I'm going to cum too, Chris."
"Do it, cum with me," Chris retort deliriously, connecting her lips with her kouhai, her body threatened to come undone with its reward on the line.
The interrogation regarding cumming inside was not even worth addressing. Raw sex was just mandatory to them, and Chris being on the pill was their preemptive measure to an unplanned pregnancy.
It expectedly worked so far and it would have to in the future as well, as Chris wouldn't give up on the wondrous feeling of having Hibiki cumming inside her and filling her with her semen.
She moans into the kiss as Hibiki pistons inside her with finality, equally holding her body down flushed against her pelvis against pelvis, penis bottoming fully into breached cervix.
A few seconds of engorged cock pulsing with rushing load climbing the urethra, and the next, cum was being expelled out to paint Chris' uterus white.
Their hold on each other tightens, Chris' orgasm exploding as ropes of genetics erupt inside the depth of her womb, coating and washing all over the walls of her baby room.
Pussy walls and lips were clamping around the pole spreading and filling her as more spurt of molten goo flooded the inner sanctum with relief, tightening and wringing every drop of sperm available until Hibiki has no more to give.
Chris rolls her hips in circles when she felt the afterglow of her glorious climax setting in her, coercing a few more drops of jizz out from Hibiki.
Her eyes flashed in and out between usual amethyst and pink, a phenomenon she was unaware has been occurring more often in the wake of the heat in her womb being alleviated by a creampie.
The duo let out a pleasant sigh of both relief and temporary contentment, pecking each other lips.
Hibiki then broke the silence with a proposition. "Bedroom?"
A rhetorical question as to where the two would take their activity next.
Bedroom
"You feel so amazing, Chris," Hibiki' voice resonates into the bedroom.
The two teenagers were once more in the last stretches of their current round, drawing each other lust and love out.
Hibiki was pistoning Chris' twat, the latter lying prone, face buried into her pillow and cumming repeatedly to Hibiki's rough pace.
Her voice was muffled by the pillow, eyes rolling to the back of her head as Hibiki sheath herself inside fully before blowing another hefty load of her spunk into her bloated womb.
Hibiki pressed her full body against her lover, her chest pancaking on Chris' back, her hips bucking against her pelvis as a new load of gooey semen flooded the vulnerable uterus turned into its playground, overflowing with more potent essence, the cervix previously keeping the broad tip at bay has given access, rolling down her shaft and letting the baby room drank in every rope of virile chowder at the expense of inflated uterus, bulging fallopian tubes, and drowned ovaries.
She hugged her tightly, wrapping Chris' body with warmth the same way her insides were until she was spent.
Hibiki rolled herself and Chris on their sides, spooning the smaller senpai with her body, interlacing her legs together, and depositing sweet kisses anywhere her lips could reach.
After regulating their panting, as well as her fuck brain piecing itself back together, Chris' voice suddenly reaches her ears.
"I think the party should be on the 25th. Like that, the 28th is still open for a more private party with just friends in the afternoon if you guys want to."
Hibiki hums in acknowledgment, barely put out that their earlier subject of conservation was being resumed. "That would be your afternoon, what about your morning?" She asks curiously as Chris specifically sets a time for the party.
Chris hums in turn, not having thought much aside a lazy morning at her own pace. "Nothing I guess."
"Nothing?"
"Yep, nothing. Just a lazy morning to myself." She confirms initially, then an idea sprouts. "But… maybe I wouldn't mind being woken up by someone sneaking into my bed and doing things to me to start the day on a high note." She glanced at her partner with a knowing smile and a raised eyebrow.
Hibiki smiles conspicuously in return, understanding her assignment for D-day. "You can count on me. I will replace your alarm clock that day."
The two not-so-lover kiss over Chris' shoulder before cuddling against each other, their sex still intimately connected until the mood for another round settles again.
The evening had barely settled in, and with how things were turning, Hibiki would undoubtedly be sleeping over Chris' place, something the kouhai was not doing enough in her book.
