Chapter Text
Having only just recently become aware of how attractive her girlfriend was, Rina would often still be spying on Ai when she was around other members of Nijigaku, feelings that she couldn’t explain swelling up inside of her as she struggled to understand just why she felt her chest tighten up when she caught sight of the gyaru’s panties or her impressive cleavage. Rina had just been introduced to the pleasures of masturbation and her own body’s desires, and while she was still growing accustomed to them and coming to terms, the pink-haired girl still felt way too embarrassed to dare ask Ai to give her that same pleasure from the nurse’s office. Her relationship as a whole had grown closer and more intimate with the blonde, but Rina still found that expressing what she was feeling while spying on her girlfriend to be more than she could handle unless Ai pressed her about it, which she would never have given how carefree and easygoing she was.
“Rina, whatcha up to?” Yu asked as she got on her knees and peeked into the NIjigaku clubroom, joining the pink-haired girl who was shocked that someone else had interrupted her in her secret spying mission. It didn’t exactly take long for the dark-haired girl to piece together what was going on as Ai appeared to be the centre of attention both in and out of the clubroom presently, with Ayumu, Setsuna and Kanata alongside her in the room, although the sleepy brunette was taking her normal afternoon nap on her pillow, leaning forward onto the desk without a care in the world. “Ai sure is sexy, isn’t she? If her being a gyaru alone wasn’t enough, her chest and butt are both huge. It’s like her uniform can barely contain her body, right?” Yu licked her lips as she vocalised what made the blonde so appealing to her, having been known throughout Nijigaku as an unfaithful lustful girl who would more often than not be truthful with what she thought of everyone, especially those with sex appeal.
Rina stayed quiet as Yu’s words repeated over and over in her head, the young innocent girl struggling to understand just why the twin-tailed upperclassman was saying such things despite knowing that both Rina and Ai were happily dating one another. She did question for a moment if Yu really was dating Ayumu given how her horny gaze would skip from one member of Nijigaku to the next, but Rina thought that it was best left to be addressed another time, preferably when her own girlfriend wasn’t being lusted after right in front of her. Now that she stopped and thought about it, the pink-haired girl did find that Ai’s chest and rear were rather large, that her small uniform only made her stand out and more eye-catching for everyone, which made Rina’s stomach begin to stir as she felt foul emotions swelling within her. Was she jealous? Was she angry at Yu? She didn’t know, but the girl with her Rina-chan Board in front of her face let out an uncertain yet quiet, “Is that right?”
“Oh yeah, totally! You wouldn’t believe the amount of panty shots I have saved on my phone from just Ai alone! Heck, I’m not the only one; you could ask around the group and I’m sure they’d own up to having at least one picture of those sexy panties,” Yu’s eyes were sparkling as she carried on about how everyone found Ai to be attractive, which came as a surprise to young Rina who was overwhelmed by such a revelation, having never thought that others would lust after her girlfriend in such a manner. The pair just quietly continued to watch the group within the clubroom before they were surprisingly joined by Karin, Kasumi and Emma, all of which just quietly watched on as they didn’t want to disturb whatever it was that Yu and Rina were up to, curious to find that they were just spying in on the clubroom. “Rina, have you and Ai done it yet?” The twin-tailed girl asked as if it wasn’t a big deal, making the group looking into the clubroom let out a gasp in sync with one another, all except for the pink-haired girl who just stayed quiet as she contemplated what Yu meant.
What does doing it mean? Held hands? Kissed? If so, then yes she had done those things with Ai, several times in fact, although she was always being the one led into doing so as Rina was much too embarrassed and naive to initiate those things herself. Or maybe Yu was referring to something perverted? It didn’t really cross her mind at first, but the pink-haired girl did know that the manager of Nijigaku was the most dirty minded of all of her friends, so maybe she should have expected that this was what Yu meant. The memory of her time in the nurse’s office with Ai and what the blonde’s hand did to her body came rushing back to her, Rina’s face turning bright red, though thankfully she had her trusty Rina-chan Board to hide behind as she babbled, “N-N-N-No.” Even if she did have a small amount of experience doing perverted things with her girlfriend, the pink-haired girl would rather die than admit to Yu, let alone a small group of Nijigaku about how far along she was in terms of progression in her relationship.
“Aw really? I don’t expect you to be the one to start things off, so I would’ve thought that Ai would’ve tried to have done something by now. Heck, I would be making love to her all day everyday if I could,” licking her lips, the perverted Yu received several disappointing sighs from Karin, Kasumi and Emma, all of which were just staying quiet and didn’t know when they could join in on the conversation. The fact that the twin-tailed girl was so shamelessly stating that she would lay her hands on Ai if given the opportunity in front of Rina left a sour taste in the trio’s mouths as they felt like they couldn’t put up with this twisted show that Yu was putting on, each of them sharing a nod in agreement as they grabbed hold of the dark-haired girl, with Karin and Emma pulling the girl by her arms into the clubroom while Kasumi gave an apologetic bow to Rina before following close behind them. “W-What are you doing? L-Let go of me!”
Rina was lost for words unsurprisingly, having come to the realisation that her relationship with Ai was lacking in intimacy with one another, the likes of which Yu would quickly and easily fill the gap of if she was even given the slightest of opportunities. The pink-haired girl’s stomach continued to churn as that dreadful feeling from earlier continued to swell within her, before Rina decided that she would confront Ai about this and try to work something out together, and maybe have the blonde explain to her just what it was that was causing her such discomfort. Quickly and stealthily entering the clubroom while everyone’s attention was turned to Yu as she had been dragged into the room and was carrying on, the pink-haired girl reached her girlfriend, shyly and weakly tugging on Ai’s shirt to grab the girl’s attention, being met with a gasp as the blonde realised that it was Rina who had snuck up on her without her realising. Lowering her voice and bending over so that she could whisper into her girlfriend’s ear, Ai spoke with a spring in her voice, “What’s up, Rinari? Do you want to go somewhere alone together?”
With a slow nod of the head behind her Rina-chan board, the couple took off hand in hand with the blonde leading the way before arriving at an empty classroom that no one would likely disturb them in. Sitting on a desk with her legs spread so that her panties were completely in view of Rina, Ai had no shame in revealing herself to her cute girlfriend, not really bothered by it as it wasn’t a huge deal to her if anyone caught sight of her underwear as she must have flashed it way too many times to count. Her uniform was still a tight fit, with numerous buttons undone on her shirt that revealed the valley of her cleavage for everyone and anyone to gaze at, and her skirt still barely covered her rear, making it easy for her panties to be shown by accident, although she had been forgetting to wear a pair of shorts underneath her skirt to stop this from happening. It was easy to say that Ai was just as sexy and appealing as she was when she and Rina had fooled around in the nurse’s office not long ago.
“So what’s eating you, Rinari? You seem bothered by something,” Ai pointed out the obvious as Rina was so distracted that her Rina-chan Board was hanging down in her hand, so close to falling to the ground that even the blonde was worried about it. She could try and piece things together, given how Karin and Emma dragged Yu into the clubroom just shortly before Rina came in, which Ai assumed that the twin-tailed girl had something to do with what was causing her girlfriend to be absent minded. She could try and guess whatever was going on through the pink-haired girl’s head, but the blonde knew that it would just be easier to hear it first hand so that she could offer some advice and try to help with whatever the problem may be. “Take your time, there’s no rush. I’ll help you however I can, okay?” Winking and giving Rina a reassuring smile, Ai just continued to sit on the desk with her legs spread apart, patiently waiting for her girlfriend to open up about her feelings.
“Yu was… Making comments about you… Saying how she would love to do.. D-D-Dirty things with you if given the chance,” weakly spitting out what had happened just earlier, Rina felt embarrassed retelling it to her girlfriend’s face, ashamed of herself for being so worked up and bothered by what Yu had admitted to her face. The innocent and troubled girl knew that she was going to be asked to explain her feelings on the matter, so she stopped for a moment to contemplate what she was experiencing, particularly that unsettling feeling in her gut. “U-Um.. T-There’s this.. Awful taste in my mouth… And my stomach is… Twisting and turning.” Looking down at her feet, Rina felt somewhat proud of herself for being able to communicate what was troubling her without being prompted to do so, although she knew that she still had a ways to go with her confidence about doing so.
“Yu said all that to your face, huh? Is that why Emmacchi and Karin pulled her into the clubroom earlier?” Ai wasn’t particularly surprised by the lack of tact from Yu, but for her to have the nerve to say such things in front of innocent Rina left the blonde feeling quite anxious about what happened to her girlfriend when she wasn’t around. Receiving a nod of the head from the pink-haired girl standing in front of her, Ai began to wonder just what it was that her partner was feeling; it was more than likely jealousy, but she just had to be sure that that was all it was. “Did that make you jealous, Rinari? Did hearing that make you want to keep me all to yourself?” A part of her was happy at the idea that Rina was protective and didn’t want anyone to get in the way of their relationship, but there was just something unsettling that Ai felt about this whole endeavour that she wasn’t sure about.
Was this stomach churning feeling jealousy? Rina didn’t know, but Ai wasn’t exactly so certain about it either, as she wasn’t insisting that that was all it was. Perhaps it was dissatisfaction with Yu’s behaviour, wanting to prove the twin-tailed girl wrong and to make the blonde hers and hers alone? She could spend forever thinking to herself about all of this, but Rina knew that it was just better to talk it out with her girlfriend. “U-Um.. Ai.. My body feels weird.. Can you.. You know.. Do that thing again?” Feeling like she would die of shame, the pink-haired girl hid her face behind her Rina-chan Board that had an expression with its eyes shut with a wavy mouth, almost mirroring how she was feeling. She couldn’t believe what she had just said, that she wanted Ai to give her the same pleasures from their encounter in the nurse’s office. A part of Rina hoped that this would be enough to rid those conflicting feelings from her body, that this would give her the clarity so that whatever it was that was bothering her was no more.
“R-Rinari? You want me to give you a handjob again?” Ai had to do a double take on what she had just heard, not able to believe that Rina had just asked for a sexual favour just like that. She personally had no problem with giving her girlfriend whatever it was that she desired, but it still came as a surprise that this was one of the first things that Rina had asked for since they became a couple, the quiet girl usually just using body language to communicate what she wanted instead of using words. With the pink-haired girl nodding her head behind her sketchbook, the corners of Ai’s mouth turned upwards as she was happy that her girlfriend was growing, “Heh alright. Take a seat, Rinari. I’ll give you one of those handjobs that you seemed to love.” Jumping to her feet and her breasts springing up and down, the blonde knew that Rina’s eyes were glued to the large orbs as they lost momentum and returned to just hanging on her chest. Signalling for the smaller girl to take a seat, Ai kneeled on the ground next to the seat that the pink-haired girl was now occupying.
Grabbing hold of Rina’s skirt and pulling it down between her ankles, Ai was surprised to see that her girlfriend’s dick was already sticking out from within her panties, the rod protruding from the waist band as it stood tall and hard. Hooking her fingers into Rina’s underwear and pulling them down to rest just above the girl’s skirt, the blonde let out a gasp of awe as she got to see her girlfriend’s package for the second time, admiring the 7-inch cock that looked painfully erect with a pair of golf-ball sized testicles hanging beneath it, resting on the chair between her spread legs. The pink-haired girl was embarrassed, still clutching her Rina-chan Board tightly in front of her face as she flipped pages to one where one of her eyes was closed while the other was half-open, with her lip being bitten. It all came so suddenly for poor Rina that she let out a gasp as Ai’s hand shot up and wrapped around her girl penis, her fingers overlapping as she began to pump along the shaft without even giving the futanari a chance to become accustomed to the sensation of having a warm hand on her dick. “A-Aah! A-Ai!”
“You’re even harder than you were last time, Rinari. I bet this boner of yours is what’s been causing you distress, no?” The blonde said in a teasing tone, the words rolling off her tongue as she knew that this was all too much for Rina to handle yet again. Ai hoped that perhaps this would be enough to rid her girlfriend of whatever was troubling her, that whatever it was that Yu had planted in the pink-haired girl would be pulled out before it had a chance to sprout and bloom. She did think about using both of her hands to service Rina’s dick, but the gyaru decided against it as she could barely even wrap one of her hands around the girl penis, not wanting to fumble with trying to use both. Her hand was quick as if pumped along the pink-haired girl’s shaft, as if Ai was shaking up a can of soda frantically so that it would blast open and shower whoever the unfortunate soul was that happened to open it, although in this situation, it would be herself being drenched in Rina’s cum when she eventually hit her approaching orgasm.
“Hah. Aah! A-Ai! AI!” Rina screamed throughout her moans as her back arched, her entire body shaking as that wonderful feeling rushed through her, feeling like something inside of her had erupted as her cock began to swell up inside of the blonde’s hand before strands of white goo began to blast from the tip, flying upwards before gravity forced them downwards onto the surprised Ai, who let out a squeal as Rina’s cum began to land on her breasts, the hot spunk almost burning her skin as it slowly dripped down into the valley of her cleavage and pooled up there. With a total of six spurts of her seed erupting from her cock, the pink-haired girl had been moaning constantly before her orgasm came to an end, her breathing becoming heavy as she recovered from how intense that sensation was, one that she had yet to become accustomed to. Her Rina-chan Board had fallen to the ground beside the chair during this, with the girl’s eyes now clearly rolled up into her head as Ai slowly pulled herself back from her girlfriend, her tongue lapping away at the small amounts of cum that were coating her hand.
Given that Rina was still a virgin and that this was only her third orgasm, Ai couldn’t fault the girl for being such a quick shot. Having licked her hand clean of her girlfriend’s sweet seed, the blonde looked down at her breasts to see just how much cum was on them, letting out a shocked gasp as she realised that there was a pool of white goo that was slowly dripping downwards and staining her shirt. “Jeez Rinari, you let out a lot this time! Just look at what you did to me! My poor uniform was almost caught in the explosion from this big guy!” Pouting as she pretended to act upset at her girlfriend, Ai poked Rina’s dick that was still just as erect as it was a moment ago, a part of her hoping that the cute futanari would ask to go further than just a mere handjob as her panties were beginning to grow damp from thinking of the pink-haired girl in a sexual manner, as guilty as that made the gyaru feel. It wasn’t her fault that Rina just had to have a big penis hanging between her legs that seemed to want more attention.
Rina’s head was spinning as the world around her slowly returned back to normal, quickly noticing that her lower half was still full of life and ready for more. It felt like her dick was ready to explore already despite just having blown her load a moment ago, with her stomach still churning and those troubling feelings still swirling about inside of her. “A-Ai.. Please?” Rina looked into her girlfriend’s eyes while pleading, the embarrassment that was making it difficult for her earlier now no longer stopping her as she had become a slave to her own desires, wanting Ai to relieve her and make her dick settle down. Sitting there slumped over in the chair, the futanari was starting to become impatient as her cock seemed to be gradually growing more upright, eventually staring directly up at the ceiling, her body fidgeting as she was craving for more of the blonde’s hand to service her.
“I don’t mind Rinari, but are you fine with just my hand? You don’t want to try something else?” Seductively, Ai leaned forward and gave her girlfriend an excellent view of her cum-covered breasts before slowly pulling back and pulling her skirt upwards to reveal her purple thong. Why she was wearing such a sexy piece of underwear was anyone’s guess, but the blonde did find it exciting to wear such provocative panties in public, the risk of being discovered sending a rush through her as she didn’t particularly mind if someone saw them or not, but the thought of it alone was exhilarating. Ai had been mistaken for a slut way too many times to count, and at first it did bother her and angered her even, she eventually stopped caring about whether she was portrayed as one or not, just wanting to be herself and not be held down by any restrictions that may tarnish her image. It didn’t help her that her sudden growth spurt made it more difficult for her to try and appear like she wasn’t doing it on purpose, as beforehand she at least had fitting clothes that didn’t show off more skin than was appropriate for a girl her age.
Rina froze at the suggestion that they could go further than just a handjob; Ai’s huge breasts looked soft, and the futanari imagined for a second what it would feel like to have those orbs wrapped around her cock and trying to squeeze her dry. Then there were the blonde’s panties; they were so indecent and perverted, yet Rina was excited at the thought of being the first person to see what was beneath them, to lose her virginity to the girl she loved and cherished more than anything. Nodding her head like an excited child, the pink-haired girl couldn’t decide what she wanted as she was fine with letting Ai take charge and lead them down whatever it was that they were going to do next. The gyaru stood to her feet as she seductively raised her skirt upwards to reveal her purple thong to Rina, sinking her fingers into the thin strings that wrapped around her waist as she pulled them down her long, slim legs before kicking the wet underwear to the side, closing in on the seated futanari as she straddled her lap, still wearing her uniform and not caring if it got dirty from here on out.
“You’re going to graduate from being a virgin, okay Rinari?” Ai whispered into the girl’s ear with a smile on her face, pulling herself upwards and reaching down to position Rina’s cock so that the head was pressed up against the folds of her pussy, unable to see beneath her skirt as it blocked their intimate parts making contact with one another. It was more exciting this way was what the blonde ponytailed girl thought as she braced herself, dropping her body down onto Rina’s as the girl penis tore through her folds and straight into her pussy, the pair of them both letting out deep moans from the sensations. For Ai, it felt as if her insides were being torn open, but not enough to cause discomfort or pain as her girlfriend’s size was just perfect. For Rina, it was as if her cock was melting as the blonde’s walls squeezed down on her, the hot and wet embrace that was Ai’s womanhood leaving the young futanari lost for words as she could only let the overwhelming pleasure sweep through her.
The pair sat there locked to one another as they grew accustomed to the feeling of having their bodies connected, neither of them wanting to separate as they were content with making the most out of the moment. As the minutes on the clock began to tick away, Ai felt like she had best actually start moving, raising her hips upwards slowly until only the tip of Rina’s dick remained inside of her snug pussy before plunging herself back downwards, the pair both moaning in unison, although the pink-haired girl’s was deeper and more drawn out than the blonde’s. The pleasure Ai herself was experiencing was enough to make her body grow weak, but she felt obligated to be the one in control and to do all the work while her precious Rina sat there and enjoyed herself, pulling herself back up and beginning to work herself into a rhythm where the wet slapping of skin hitting skin would fill the room constantly, with only a second in between as she frantically plunged herself along her girlfriend’s shaft, wondering just when Rina would reach her limit and blow her load.
The futanari knew that she wasn’t going to last much longer, with the new intense pleasures that were rocking through her body wearing her down, her cock being swallowed up by Ai’s greedy pussy over and over. She could barely believe that she was making love to her girlfriend, but Rina didn’t have much time to think much of it as wave after wave of pleasure rushed through her, leaving her moaning and panting heavily as her body grew even hotter than earlier, although she thought that it must be because she was having sex with Ai. “O-Oooh! A-Ai!! CUMMING! ” The small girl couldn’t hold herself back any longer as she let out a howl that shook the room, a loud sound coming from such a tiny frame would’ve left even Ai shocked, but the blonde was too engrossed in wringing Rina’s cock dry. With one final slam of her hips down into her girlfriend’s lap, the gyaru could feel that girl penis inside of her beginning to swell up as cum began to work its way up the shaft, ready to explode in just a second.
One, two, three quick spurts in succession blasted out of the tip of Rina’s cock and painted the insides of Ai’s pussy, the volume of these few shots being significantly more than when she came from a handjob just earlier. The thick, gooey substance stuck to the walls of the blonde’s womanhood, the heat being enough to trigger her own orgasm as she wrapped her arms around Rina’s neck, pulling her in for a hug as she buried the pink-haired girl’s face in her cum-covered breasts, needing to use her girlfriend as support so that she didn’t fall over backwards and onto the ground below. Several more spurts of Rina’s baby batter erupted, with each of them progressively having less and less volume to them before the futanari’s orgasm came to an end, her head still spinning as her vision was dark from being suffocated by Ai’s breasts. She felt like she had been drained of everything, her cock beginning to shrink back down as the tight embrace of her girlfriend’s pussy was beginning to disappear as she felt a thick goo begin to slowly drip downwards and envelop her member before continuing to run down and onto her own crotch.
“R-Rinari… You let out so much… W-Was it that good?” Ai weakly said as she pulled herself away from the pink-haired girl, giving her the room to breathe and not be suffocated by those large breasts. As sorry as she felt for crushing poor little Rina like that, the blonde couldn’t really keep herself feeling pity for the girl as she realised just how much cum had been shot inside of her, and without a condom of all things. The risk of pregnancy was something that had just hit her now, and while she was in the heat of the moment and had taken Rina’s virginity without protection, Ai could only pray silently that she wouldn’t end up becoming pregnant with her girlfriend’s child while she was still in high school. Maybe when they graduated and were able to provide for themselves, but not now of all times. What would the rest of Nijigaku say to her if she wound up pregnant? Struggling for a moment, Ai slowly pulled herself up off of Rina as excess baby batter began to drip out of her pussy, with a good chunk of it landing on the floor beneath her as she put some distance between her and her girlfriend.
“A-Amazing..” A single word came from Rina’s mouth as she laid there with a look of satisfaction printed across her face, her eyes still rolled back into her head as she would occasionally twitch from the waves of pleasure rocking through her earlier, her body still not yet recovered from how intense it was. Although there was one thing that bothered her; that nasty feeling that had been bothering her in her stomach was still present, and it just made Rina wonder just what on Earth it was that she was experiencing and feeling for this to happen. Whatever it was, the pink-haired girl made a mental note to go and seek advice from the rest of Nijigaku about what it could be that she was feeling if even Ai wasn’t able to help out.
