Work Text:
“What are you up to this time, Shiki?” Setting down a cup of tea near the science nut who was hunched over her work bench, fiddling away with a beaker and test tubes, Mei had grown used to seeing such a sight. Ever since she started dating Shiki, she got to witness it on an almost daily basis.
Putting down her science equipment carefully, Shiki straightened up as her heart skipped a beat. Just having the redhead around put her at ease, and she knew without a shadow of a doubt that she was madly in love with Mei. After all, they were previously loners, and she felt a companionship forming ever since.
“Thanks Mei. I’m just working on something that will help lesbian couples conceive a child together without the need for a third party’s sperm,” reaching out and grabbing the cup, Shiki inhaled the sweet scent before bringing it to her lips, taking a sip of the jasmine tea that her girlfriend prepared for her.
Wanting to put her brain to good use instead of just following her every whim, Shiki had buckled down and was trying to resolve issues that the average person would face throughout their lives. She’d developed a hair growth formula not too long ago, and had even managed to create a drug that soothes the mind and eases one of their anxieties temporarily.
As a result of her efforts, it was no surprise that Shiki was quite wealthy, yet she didn’t yearn to live the luxurious lifestyle. She was more than content with staying down to Earth, and with Mei by her side, she was happy to make do with whatever her girlfriend chose for the two of them.
While Mei did want to move into a big house at first, the realisation that it’d be quite empty if it was just herself and Shiki made her quickly brush aside such a thought. They were still young adults after all, and while she had thought about raising a family of her own, she knew the time wasn’t quite right.
It was a simple decision that the two were both happy with, deciding to live together in a regular apartment. Shiki had a room entirely for her studies, having renovated the place to suit her needs, and Mei was more than willing to let her eccentric girlfriend have such freedom, given the money she brought in.
“Is that right? And just what gave you that idea, hmm?” Deciding to poke fun at her girlfriend while she wasn’t focused on her work, Mei figured that it was wishful thinking to assume that Shiki was doing this for themselves. The redhead had brought up the topic once or twice before, but she quickly grew embarrassed and brushed it aside.
“You did.”
It was such a simple response from Shiki, but she meant it sincerely. If it wasn't for her loving partner, she would never have thought about trying to help lesbian couples have children of their own. She found it absolutely adorable the way Mei would bring it up only to change the topic within a matter of seconds.
“D-Don’t just say that so casually..” Blushing as she averted her gaze and looked around her girlfriend’s lab, Mei could never get used to how straight forward Shiki was. They’d been together for many years now, yet it still made her all skittish and jumpy, clammering up like a girl who had just been confessed to.
With a satisfied smile on her face, Shiki set down the cup of tea as she rose to her feet, fixing her white lab coat so that it was straightened up and not loose. Wrapping her arms around the flustered Mei, she brought the redhead in for a hug, pressing their bodies together as they stood there in silence.
Mei could never get a read on Shiki's thought process, not even after sticking by one another’s side for so long. It just baffled her with how eccentric her girlfriend was, but it’s not as if it was a bad thing. She genuinely adored the strange behaviour, even if it got on her nerves from time to time with how unpredictable things could be.
“Do you want to try it out, Mei?”
“Try what out?”
“I have some samples for this project I’m working on. Or do you want me to spell it out to you?” Feeling somewhat daring, Shiki was in need of some results to help further her research, and while she had tested to see if it was safe for human consumption, she hadn’t noted down how effective the drug was.
Falling silent as it all clicked together in her head, Mei buried her face against Shiki’s chest as she understood the implications well and clear. Her girlfriend was asking to have sex, albeit in a roundabout way. Although this time would be different; they’d be making use of an experimental drug that was aimed at helping lesbians conceive.
“S-Sure..” Mumbling under breath, adrenaline was coursing through Mei’s veins as she knew this was going to be quite thrilling if it didn’t blow up in their faces. The last time they’d made use of Shiki’s concoctions in the bedroom, they’d engaged in a marathon of mind blowing sex lasting 6 hours.
Just remembering that day sent a shiver down the redhead’s spine, and she was hoping that Shiki’s latest work was going to be just as amazing as her last. While she wanted to have no doubts, the amount of broken equipment and explosions as of late had caused Mei to be somewhat wary.
Grabbing a small container that was filled with red and white pills, Shiki intertwined her fingers with Mei’s as she led them out of her lab and towards their bedroom. While on the surface it appeared as if she was composed and had it all together, she was actually a nervous wreck that was just barely managing to stay calm.
Closing the bedroom door behind them and dimming the lights, Mei and Shiki both undressed one another, tossing the lab coat along with their clothes to the floor as they stood naked before one another. They showered together almost daily, so it wasn’t like this was new, but the pair were still embarrassed to expose themselves to their lover.
The slim blue-haired woman’s bosom was the first thing that caught Mei’s attention. Shiki had always been busty, and ever since they started living together, she could have sworn that her lover’s breasts grew bigger the more she fondled them. She didn’t have any evidence to back it up of course, but the thought persisted all of this time.
That wasn’t to say that the redhead wasn’t sexy in her own right. Far from it. Mei’s slender body had curves in all the right places, and while she didn’t have much meat on her, it was more than sufficient for Shiki as she would always caress every nook and cranny with her fingers and even her tongue.
“Y-You go first, Shiki,” Mei squeaked out as she was shivering nervously, unable to imagine what awaited her in just a moment’s time. She wanted to be held in Shiki’s arms and treated like a princess, yet just knowing that this experimental drug was supposed to assist with baby making left her curious.
Just what is going to happen?
Pouring a white and red pill onto the palm of her hand, Shiki popped it inside of her mouth and swallowed, not needing any fluids to help get it down. She’d grown accustomed to being her own test subject ever since she discovered a passion for science, and to say it was all smooth sailing was an understatement. Nevertheless, the eccentric woman didn’t let it bother her.
Standing there as she awaited the effects to kick in, Shiki just stared lovingly at the redhead, wanting to see the adorable yet erotic faces she made when they made love. Mei was a bottom, and she absolutely adored being dominated and pushed around, and the eccentric woman was more than willing to fulfil those desires, even if she wanted to be on the receiving end for a change.
“D-Don’t stare at me like that.. Say something!” Looking away as she couldn’t bear the silence much longer, Mei knew that it was only a matter of time before something changed. Hearing Shiki mention earlier how it was supposed to help lesbian couples conceive left her confused, even though it should’ve been obvious.
“Something,” playing along as she just retorted with a straight face, Shiki held back the urge to laugh at her childish act. She simply loved getting on Mei’s nerves like this, especially when the redhead was the one to start it. The science nut would never do anything to hurt her girlfriend’s feelings however.
Groaning as she should have expected as much, Mei just shook her head in disbelief as she eyed up Shiki’s slim and fit body. Despite staying holed up inside of her lab for a majority of the day, the eccentric genius still made time to sneak out of the apartment and head outdoors to work up a sweat and search for bugs to keep as pets.
Long legs with surprisingly thick thighs that were quite firm, a flat stomach that wasn’t far away from gaining some definition on her muscles, large breasts that were just a tad too big to fit in the palm of her hands, a heart warming smile. All of these things Mei simply adored about her girlfriend’s body.
Even her two huge girl cocks.
Wait, what? Rubbing her eyes and pinching her arm, Mei couldn’t believe what she was seeing. She looked away for a brief second, and the next thing she knew, Shiki was sporting not one but two flaccid penises, with a surprisingly large set of testicles dangling between her legs.
“What’s wrong, Mei? Oh. That isn’t supposed to happen,” confused as to the alarmed look on her girlfriend’s face, Shiki glanced down and realised what the problem was. The experimental drug was supposed to temporarily give her a set of male genitalia, but to see that she was now sporting a pair of dicks made her wonder where she went wrong.
It was a sample for a reason, and she wasn’t about to make a big deal over it not panning out as planned. Shiki was used to miscalculations, having grown to accept that not everything will be perfect, that it was all a process of trial and error, so she didn’t quite understand why Mei was so distressed.
“W-Why did you just grow a penis..? And two at that!” Stuttering out in disbelief, Mei flinched as she stepped backwards, shocked that her girlfriend was a mad scientist. She had never seen a single one of Shiki’s experiments fail, and this was just so hard for the redhead to take in so suddenly.
Wanting to put her anxious lover at ease, Shiki stepped forward, causing the dual rods that were positioned next to one another to sway about. Placing her hands on Mei’s, she reassuringly proclaimed, “There’s nothing to be scared of, Mei. This isn’t quite how it’s supposed to turn out, but I assure you, this is to help couples conceive children of their own.”
“B-But it’s so.. So vulgar! C-Couldn’t you think of another way?” Shaking as she was so close to her girlfriend’s newly grown penises, Mei couldn’t take her eyes off of the crude members. They’d experimented with dildos and an assortment of sex toys before, but none of that could prepare her for this shocking development.
Guiding her distressed lover towards the bed, Shiki sat down beside Mei as she continued to hold her hand, not letting go for even a second. This is the most efficient means of allowing couples to have children without a third party, yet explaining it to the redhead was proving to be quite troublesome given that she wouldn’t stop fidgeting.
“Relax, Mei. We can stop things here, okay? I’ll stay right here by your side until you’re at ease. There’s nothing to worry about. I won’t hurt you,” uttering comforting words with a sincere smile on her face, Shiki felt it was best to worry about putting Mei’s nerves to rest, to ensure she wasn’t on edge all night.
“A-Aren’t you ashamed to have those.. Things attached to you?” Nudging towards her girlfriend’s genitals, Mei just couldn’t bring herself to accept this situation. It was so surreal, like it was straight out of a movie, yet with Shiki sitting right by her side like this, the confirmation that this was the real deal sank in.
Mulling over the question for a moment, Shiki shook her head, denying the thought as she wasn’t bothered in the slightest about her current predicament. It wasn’t going to affect her daily life after all. What was there to worry about? “This is the fruit of my research, Mei. Why would I be?”
“Weirdo..”
Sitting in silence as she shifted on the spot, Mei just couldn’t get comfortable as she would sneak glances at Shiki’s members, finding her disgust gradually disappearing, only to be replaced with curiosity. There was just something about seeing her girlfriend looking like this that made her heart skip a beat.
It’s supposed to help people start families without seeking donors. Couples like us. Rationalising the situation inside of her head, Mei took a deep breath as she calmed her nerves, no longer feeling on edge about seeing her blue-haired lover looking so outrageous and ridiculous.
Gulping as her interest continued to grow, Mei couldn’t help but wonder what it would be like to have sex with Shiki like this. One penis was more than enough, but two? She would be skewered! Still, the sheer idea of having a kid with her eccentric partner was sounding more appealing by the second.
“C-Can I touch them, Shiki?”
“Hmm? Sure, if that’s what you want, Mei. But don’t force yourself, okay?” Caught off guard by the sudden question, Shiki wasn’t about to say no to the redhead. Still, she had to wonder if Mei was pushing herself to do this, resulting in her making it known that they didn’t have to do this. They could stop now and call it a night.
Her arm was shaking as she reached out slowly and poked a finger against one of Shiki’s dual rods. Pulling backwards and letting out a shriek, Mei couldn’t believe that it was real. Noticing her girlfriend twitch from her touch, she did it again, only this time she ran a finger along the flaccid shaft.
To her astonishment, Shiki’s penises began to grow in size, blood flowing through them as they reached full mast in a matter of seconds. Mei was speechless as she was now face to face with not one but two erections, and they belonged to her erratic partner. As strange as this situation was, she wasn’t bothered in the slightest.
“M-Mmn. You’re so gentle, Mei,” stifling a moan as she was overcome with foreign feelings, Shiki was amazed that she had gotten hard from this. She had been meaning to test this drug for a while now, and to think that she was her own test subject, that Mei was witnessing it all with her own two eyes made her tremble with excitement.
Gazing down at her erections, Shiki didn’t need a tape measure or a ruler to calculate how long they both were. Each member was a foot long and questionably thick, making her wonder if it would even be possible to insert even one of them inside of Mei. This was something she’d need to hypothesise in her lab at another time.
Feeling encouraged by her girlfriend’s arousing noises, Mei decided to be somewhat daring as she wrapped her fingers around one of the shafts, finding that she could just barely cover the circumference. Feeling it throb in the palm of her hand was exhilarating, and just knowing that it belonged to Shiki made her begin to weakly stroke the huge penis.
Trembling as she felt unknown pleasure rush up her spine, Shiki could hardly believe that she was being jerked off by Mei, even if she was being somewhat gentle and cautious. This wasn’t what she predicted, given the redhead’s outright shock earlier, but she was pleased with this development.
“You can be more aggressive, Mei. I’ll be fine,” encouraging her entranced lover onwards, Shiki’s chestnut-coloured eyes went wide as she wasn’t prepared for the sudden burst of speed and tight grip surrounding her penis. Placing her arms on the bed for support, she began to howl ecstatically.
“Whoa.. I never knew you could make those kinds of noises, Shiki,” amazed with the erotic noises leaving the science nut’s lips, Mei pumped her hand swiftly, keeping her fingers wrapped around it firmly as she ran her fingers from the mushroom-like tip all the way down to the base and back up fervently.
Transparent liquid began to flow from the glans and down the shaft, acting as lubrication for the redhead as she found it much easier to work her hand along the length. It took Mei a moment to realise that this was precum, a telltale sign that Shiki was in fact aroused, and it was only then that remembered that there was another penis being neglected.
“I’m sorry, Shiki. I’ll take good care of you, okay? Just um.. Sit back and enjoy yourself, I guess?” Apologising as she got up and knelt between her girlfriend’s legs, Mei wasn’t quite used to making orders in the bedroom. She was inept when it came to dirty talk, something that Shiki more than made up for on her own.
Her eyes rolled back into her head as she had both of Mei’s hands wrapped around her dual rods, and Shiki moaned loudly as she trembled, struggling to withstand the waves of pleasure crashing through her body. This was all so much for her to take in, yet she was loving every second of it.
“F-Faster Mei! Your touch is the best! I-I won’t last much longer at this rate!” Pleading for her girlfriend to speed up and show her no mercy, Shiki felt what she could only assume was an orgasm swelling up in the pits of her stomach. She absolutely adored being jerked off by Mei, and it made her wish to see this side of the redhead more often.
“U-Umm… What do I say..? G-Go on, let it all out for me, Shiki. Shower me in your love and mark me as yours,” uncertain as to how to go about spurring her partner to let the pleasure sweep her away, Mei stuttered as she continued to jerk Shiki off relentlessly, picking up the pace and tightening her grip.
She could feel the two penises swelling up in the palms of her hands, that the veins were throbbing more viciously than before, and that the sheer amount of precum being produced was skyrocketing. Mei knew what was about to come, yet she wasn’t prepared in the slightest as Shiki let out a deep groan.
“C-Cumming! It’s coming out, Mei! N-Nnngh!” Dropping backwards onto the bed as she thrashed about, Shiki bucked her hips upwards as she began to ejaculate. It was like nothing she had ever experienced before, as it felt as if something was exploding inside of her, escaping from both of her dicks in unison.
Startled as ropes of white goo shot upwards into the air and splattered against her face, Mei let out a shriek as she continued to pump her hands, unsure as to whether or not she should stop. The semen blasting out of her girlfriend’s members crossed over one another, finding their mark as it all landed on her.
It was boiling hot and surprisingly thick, and Mei couldn’t help but worry that it would leave a mark from the burning heat. It was getting into her hair, yet as she continued to coax every last drop from Shiki, the redhead was amazed with the sheer amount being produced, making her wonder when it would ever come to an end.
Her partner’s inexperienced hands continued to wring her dry, and Shiki felt as if her body was responding in kind as more semen would shoot up both of her dicks and escape. It was all so maddening, so fulfilling, and she was loving every second of this foreign pleasure that was only temporary.
Crashing her body backwards onto the bed as her orgasm subsided after more than a minute, Shiki twitched as she slowly calmed down and processed what had happened. Waves of satisfaction crashed through her, making it difficult for her to think straight, yet she was determined to sit up and look at Mei.
Not that she really could, given that the redhead’s face was plastered in a ridiculous amount of semen.
“M-Mei..”
Pulling her hands back as she wiped some of the cum from her face so that she could at least see clearly, Mei was left speechless. She hadn’t expected Shiki to produce this much, but it should have been obvious, given the two penises and massive balls that dangled beneath them.
“I’m going to go wash up real quick,” rising to her feet, Mei hurried to the bathroom and slammed the door behind her, wanting to clean herself up so she didn’t look like a mess to her girlfriend. She didn’t mean to come across as upset, but she was so worked up that it didn’t cross her mind.
She’s mad, isn’t she? Wondering to herself just how annoyed the redhead was at this moment, Shiki knew that the slamming of the door was a telltale sign that Mei was in a bad mood. She did it whenever they bickered, or whenever the eccentric woman pushed too far with her jokes or honest compliments.
Hearing the water turn off inside of the bathroom, Shiki braced herself for an earful as she sat up straight. She knew it was better to just let Mei get it off of her chest rather than try and reason with her, and she would just have to face the music. Not that she wasn’t at fault here, given she had made the mess to begin with.
Opening the door and sighing, Mei had droplets of water dripping down her cheeks and hair as she had just finished washing the copious amounts of semen off. It was more troublesome than she imagined, and she was thankful that she didn’t have to put up with this on a regular basis.
“That’s better. You let out quite a lot, didn’t you, Shiki?” Standing in front of her girlfriend, Mei was honestly impressed by all that had happened thus far. While she had been apprehensive at first, she’d warmed up to the idea of Shiki temporarily having two penises, and had even been quite bold for a change.
“I’m sorry, Mei.”
“Huh? What are you apologising for? I’m not upset, silly. Come on, raise your head,” surprised that Shiki was feeling guilty for what she had done, Mei wasn’t having any of that. She had been the one to jerk her partner off, and she had even been told that she wasn’t obligated to do so.
Looking the redhead in the eye, Shiki felt her heart skip a beat as she was met with a reassuring smile. She absolutely adored Mei’s gleaming smiles, and it made her want to jump up and hug her. She held back however, realising that she was still erect and eager for more action.
“Y-You’re still.. U-Um.. D-Do you want to..” Unable to get it out, Mei stuttered like a child as she felt her heart race. She desperately wanted to make the most of this opportunity and make love with Shiki, even if she was still somewhat worried about what those two huge dicks could do to her.
“Mei, lay on your back, or I’m going to pin you down and do it myself,” feeling her dominant side start to emerge, Shiki barked an order out that lacked a punch. She could never truly get serious when it came to bossing Mei around, and this was the extent of her ability. Hurting her lover was something she did not want to happen.
Feeling the depths of her womanhood tingle, Mei obeyed Shiki’s words without a second thought, always looking forward to being made to submit. It didn’t take much effort really, given that she couldn’t bring herself to fight back against her girlfriend when they were about to be intimate.
“That’s a good girl. Now, stay still and let me do all the work, okay?” Stroking the underside of the redhead’s jaw, Shiki placed her hands on Mei’s thighs, spreading them apart as she made herself comfortable. Bringing her face downwards, she was impressed by the sight before her.
Mei’s delicate pink folds were dripping with anticipation.
“Someone’s naughty. I guess I don’t need to eat you out, huh?” Smirking as she flicked her lover’s clitoris, Shiki was more than willing to take all the time she needed to prepare Mei for what lay ahead. But given that she was dripping wet and raring to go, the eccentric woman knew she was free to jump right into the action.
“I-I’m not naughty…” Shivering as she was berated by the one she cherished above all else, Mei let out a shriek as her clit was given some attention. She was always the one to be fingered, to be eaten out, and was always the one to be the first to experience their assortment of sex toys.
Laying there for several moments as she steadied her breathing, Mei stared up at Shiki who was grabbing hold of her already spread legs and had positioned herself so that both of her cocks were pressed up against her drenched privates. They didn’t have any protection, given that this was all new to them and was the result of an experiment gone awry, but neither of the two cared.
“Do you want me to be gentle? Or do you want to be sent to heaven, Mei?”
“...The latter, please,” knowing how wrong this all was, Mei brushed aside her desire to be treated gently and like a princess and embraced her deprived, wild side. This was a once in a lifetime opportunity after all. Or at least, it would be until Shiki finished developing this drug for the masses and worked out the kinks.
There was no way the redhead wouldn’t get pregnant if they did it without protection, given the incredible amount that Shiki had ejaculated just a short while ago. This was turning into a serious bout of babymaking sex, and the two wanted to see this through to the end, the consequences be damned.
Giving Mei a nod of approval, Shiki positioned both of her erect members against the soaking wet entrance. It was going to be a tight fit, but she was going to make this work as best as she could. If it got out of hand and her lover pleaded to stop, the blue-haired woman was more than willing to put an end to things at that moment.
Driving her hips forward with the sole purpose of conceiving a child, Shiki struggled to insert both of her dicks inside of Mei, finding that no matter how hard she tried, she needed to really put her entire body weight into it if she wanted it to happen. After a trying process, she managed to bottom herself out inside of the redhead.
“Are you okay, Mei?” Stopping to check on the wellbeing of her girlfriend, Shiki could feel the walls tightening down around her, that Mei was squirming from side to side as she struggled to withstand the pair of intruders. It was tight, and she felt like she was going to be crushed if things didn’t ease up soon.
She’d had sex with Shiki before, although it was using a strap on, so this wasn’t too unfamiliar to Mei, but the fact that there were two penises inside of her snug pussy was hard for her to bear. She felt like she was going to be split in two, but knowing that she was in capable hands, she knew she’d be just fine.
“G-Go on.. Rough me up, Shiki. I-I’ll be fine,” stuttering out as she grit her teeth, Mei wasn’t prepared for when her partner began to piston her hips like crazy, battering away at her cervix endlessly. It was an entirely new experience for the pair, yet the redhead felt like she was in heaven.
Both of Shiki’s dicks were scraping against every bump in her pussy, making her squirm as the discomfort soon turned to pleasure, and Mei was thrashing about as she revelled in the thrill of having genuine sex with her girlfriend. It was like nothing she could have ever imagined, and while she was somewhat afraid, she wanted more.
The sensation of bare skin rubbing against bare skin in such a warm yet confined space was making the pair moan euphorically. Each swing of Shiki’s hips reaffirmed that they were engaging in an act that was far beyond sex; they were going at it like animals in heat, with the intention of bearing a child in mind.
Neither Mei nor Shiki could stay rational and keep composed as they deepened their relationship. They had been dating for many years now, yet here they were, mating with one another in a way that should not be possible. Through the means of a science experiment gone awry, they were having baby making sex for the first time.
“S-Shiki! Your things are incredible! M-Mmn! I-I love how deep they reach!” Moaning as she relished in the satisfaction of having not one but two of her girlfriend’s penises inside of her pussy, Mei felt like such a fool for being so nervous earlier. This was simply amazing, and she was growing addicted to the sensations coursing through her body.
“M-Mei! I-I can’t last any longer!” The tight grip around her dual roads was wearing away at her faster than she imagined, and Shiki knew she was moments away from blowing her load. She felt compelled to announce it, to at least warn Mei of the dangers that awaited them if they didn’t stop now.
Not that Mei could bring herself to put an end to things here.
“D-Do it! K-Knock me up, Shiki! Make me a mother!” Spurring her girlfriend onwards, Mei was ready to take the plunge and become a parent. She was more than happy to be impregnated at this very moment if it was Shiki, and just imagining how adorable their children would look pushed her over the edge.
“M-Mei!!!”
“Shikiiii!”
The two cried out one another’s names as they reached their climaxes in unison, the two connecting as deep as they possibly could as Shiki leaned forward and hugged Mei, who had wrapped her legs around her hung lover’s waist to ensure that she wasn’t able to pull out and let this moment go to waste.
Shiki’s hefty balls were working overtime to produce the thicket, most potent load thus far, and her body was demanding that she impregnate Mei this very second. Her mind was melting as she drowned in pleasure, letting pure instinct and desire sweep through her as she deposited ridiculous amounts of semen into her lover’s womb.
The intense sensation of molten hot semen erupting like a volcano inside of her pushed Mei further than she thought possible, as she began to squeal like a pig as her pussy tightened up as much as it feasibly could around Shiki’s huge penises, almost as if her body was trying to squeeze out every last drop.
Planting their lips together, their tongues clashed as they moaned into each other’s mouths as they relished in their orgasms together, letting the satisfaction and feeling of fulfilment crash through them. It was wet, sloppy and wild, unlike any of their previous kisses beforehand.
The pleasure coursing through their bodies was indescribable; it was sheer perfection for Mei and Shiki, like every single nerve in their bodies was sending jolts of electricity to their brains and overloading it. The overwhelming shared climax was too much for the both of them to endure as they blanked out for a moment, despite how desperate they were to see things through to the end.
Semen was swirling around inside of Mei’s packed womb, and it was leaking out of her beaten and stretched out pussy through the thin gaps surrounding Shiki’s dicks, slowly trickling out and onto the bed sheets. It was so dirty, yet neither of them could bring themselves to separate.
Soaking in the after glory as they laid there connected for a good while, Mei and Shiki didn’t dare utter a word to one another. They just hugged it out, with the dual rods remaining firmly buried inside of the snug womanhood that was filled to the brim with potent cum. Just knowing that this would result in a child made the two shiver with joy.
“I love you, Mei.”
“Me too, Shiki. Y-You mean the world to me.”
Whispering sweet and caring words to one another, the two were starting to feel somewhat sticky as the copious amounts of semen were beginning to dry up. As reluctant as they were to part with one another, they felt that they had to, if only briefly, so that they could clean themselves up and go for another round.
Reaching over to her bedside table, Shiki grabbed a handful of tissue and began to wipe her girlfriend’s crotch down, cleaning her up to the best of her ability. No matter how hard she tried, her own cum wouldn’t stop pouring out of Mei’s stretched out pussy, making her wonder just how much was stored inside.
Tidying herself up so that she wouldn’t be uncomfortable, Shiki was shocked to see that Mei had sat upright despite being fucked senseless. She was almost certain that the redhead would be sore, that she wouldn’t be able to move a muscle without feeling pain, so it was somewhat relieving.
“T-That was incredible, Shiki. I-I don’t think I have another round in me, sorry..” Blushing as she averted her gaze, Mei had to admit that this was amazing, that it exceeded her expectations and crushed them into tiny pieces. She shivered as she felt the thick, hot goo trickle downwards inside of her, slowly escaping.
Sitting there in silence for a moment, Shiki had an idea. She had still more pills, and while she had been given a taste of Mei’s forceful side earlier, she wanted to see more of it. It was wrong, but she just couldn’t help herself as she laid backwards and spread her legs, lifting her balls upwards to reveal her womanhood.
“It’s your turn, Mei. Don’t you want to raise kids together?”
Gulping as she stared in disbelief at the sight before her, Mei had never seen her girlfriend peasant herself in such a way. Shiki was always taking the lead, and this was all new to the redhead. She was at a loss for words, and she let her emotions get the better of her as she found her voice.
“Y-You’re the worst, Shiki. I never took you to be such a pervert,” the words left Mei’s lips as she came across as disappointed, and it took her a moment to realise what she had done. Placing a hand over her mouth as she looked away, she hoped that Shiki didn’t take it too personally.
Falling silent as she processed what the redhead had just uttered, Shiki was especially weak to being insulted and disappointing her girlfriend. It made her heart ache, and as she hung her head in shame, she felt the need to see if Mei was just fooling around or not. She imagined that wasn’t the case however.
“D-Do you mean it..?” Feeling vulnerable as she began to imagine the worst, that they would break up because of this, Shiki only ever got like this when it came to her fights with Mei. Sure, they would bicker from time to time, but this time felt serious, and she began to fear that she’d ruined everything.
Guilt swelled up inside of Mei’s chest as she regretted her actions, and as she glanced around the room while trying to find the right words to apologise, she spotted the bottle of pills that Shiki had brought with them into the bedroom. It became clear to her what she had to do to make things right.
Reaching over and popping one of the white and red pills into her mouth, Mei swallowed as she could feel her girlfriend staring at her in disbelief. She had to do this. She had to make it up to Shiki, to prove that she wasn’t actually upset, and that she genuinely wanted to start a family together.
“Mei..”
“Look, I’m sorry, okay? I got worked up and.. And I said something I shouldn’t have. If this is what you want, then I’ll do it,” staring into the eyes of her stunned lover, Mei was serious. She was determined to make Shiki happy, and if she was presenting herself to her and asking to have baby making sex, then that was exactly what they were going to have.
Feeling a warm, ticklish sensation swell up around her crotch, Mei looked down and saw that she had grown a pair of penises, much like Shiki’s. They were flaccid at this moment, but it was clear from just a glance that her testicles were much larger than her girlfriend’s, and it made her wonder just how much cum she was going to produce.
Leaning back and spreading her legs as wide as they would go, Shiki felt her heart skip a beat as she understood clearly that Mei wanted to make things right, that the feeling to start a family and raise kids together was mutual. Blushing, she uttered with a straight face, “I’m all yours, Mei. D-Do with me as you please.”
Crawling forwards and trying to mimic what had been done to her just earlier, Mei struggled to align both of her members against the entrance to Shiki’s pussy. As far as she was aware, the blue-haired woman hadn’t made use of any of their sex toys for her own personal pleasure, always using them to assert her dominance.
Shiki’s a virgin, isn’t she?
“Relax, Mei. Take all the time you need, okay? Don’t worry about me. I’ll be just fine,” noticing the tension on the redhead’s face, Shiki reassured Mei that everything would be alright, that there was no need to worry. She was somewhat nervous, given that this would be her first time taking something other than fingers inside of her pussy.
Taking a deep breath as she nodded her head, Mei pressed both of the heads of her penises against the wet folds, finding the entrance after calming down. She had been worked up and worried about messing things up, but after hearing the gentle encouragement from Shiki, she decided to take things one step at a time.
“There. Push your hips forwards, Mei,” bracing herself for what was about to happen, Shiki gave a nod of approval to her girlfriend as her eyes went wide. Mei’s dicks were spreading apart her inexperienced womanhood, slowly but surely sinking further and reaching unexplored places.
Bucking forwards gently, Mei felt that she wasn’t getting anywhere at this rate. Recalling that her lover had thrust it all inside in one fell swoop, she figured that it was best to try and mimic that approach. Putting all of her body weight into it, the redhead thrust the entirety of her erect members inside of Shiki.
Screaming as her hymen was torn apart and her cervix was pounded against, Shiki was caught off guard by the sudden forcefulness. It was rough on her, but just knowing that she now belonged to Mei, that they had deepened their bond and become intimate with one another helped ease the pain.
The pained expression on her lover’s face made Mei stop dead in her tracks as she still had several more inches to go before she had bottomed out. She decided to sit still and let Shiki grow accustomed to the sudden intrusion, believing that time would help fix everything, even if she wanted to go all out and not hold back.
Moments passed as Shiki took several deep breaths, and she managed to calm down as she gave the redhead a nod of approval to keep going. She hadn’t taken the time to look at Mei’s erections, but she was almost certain that they were just as big as her own. The curiosity would have to wait though, as her cervix was pounded repeatedly in quick succession.
Swinging her hips back and forth as she worked up a rhythm and gained some confidence, Mei was starting to lose herself, wanting to submerge herself in the sea of pleasure that she had only just dipped her toes into. She understood now just why Shiki had been so rough on her earlier.
“Shiki, you’re so tight! It’s like you don’t want to separate!” Her rationality was dwindling once again as she ecstatically spoke to her girlfriend, crashing down against Shiki with all of her might, determined to bury the entirety of her huge members to the base with each relentless thrust.
Squealing and flailing about as she could hardly withstand this, especially given that this was her first time, Shiki felt that there was something different about Mei. Her actions were becoming more drastic with each passing second, and she was behaving like an animal in heat whose sole purpose was to breed.
The redhead was thoroughly enjoying taking the lead for a change, that she was actually having bareback sex with Shiki, and she just bucked her hips back and forth like her life depended on it. Mei’s movements lacked technique; she was just driving herself deep into her girlfriend’s eagerly awaiting pussy.
Both of her massive cocks were making up for her lack of skill as she was easily overwhelming Shiki, whose insides were stimulated from the vigorous thrusts that seemed to grow wilder by the minute. Each time Mei pulled back, she could swear that the walls surrounding her would tighten up, but she just slammed forward, burying herself as deep as she could.
“M-Mei! Y-You’re incredible! I-I can’t believe you’re this wild!” Amazed with the sight before her, Shiki thrashed from side to side as she felt the dual rods pound against her cervix ruthlessly, almost as if they were demanding to be let inside of her precious baby chamber and mark it as Mei’s property.
Her mind was on auto-pilot as her body moved on its own, changing positions to one that was guaranteed to see to it that Shiki wound up pregnant after this; the mating press. Mei’s sheer dominance over her partner was a sight to behold, as each harsh thrust of her dicks ran it home that she was in charge here, that no one could stop her.
Not that Shiki had any reason to; she was loving every second of being pinned underneath the redhead.
Putting her whole weight onto Shiki’s body as she drove her monstrous members as deep as they could reach, Mei’s determination won out in the end as she pierced straight through her girlfriend’s cervix and reached the forbidden area that shouldn’t be possible to penetrate; her womb.
The intense pleasure of having something slam against the roof of her womb set Shiki off as she began to squeal deliriously as it felt as if her insides were being pried open. Her pussy tightened up as much as it possibly could around Mei, in a desperate attempt to squeeze every last drop of cum out of her.
The depravity of this situation was rushing through Mei’s body as she reached her limit, having done her best to hold on to the bitter end so that she could force Shiki to climax first. Planting her lips against her girlfriend’s, the redhead tangled their tongues together as she moaned loudly.
With no warning whatsoever, the first spurt of cum erupted from Mei’s dicks and splattered against Shiki’s womb, causing her to clench down around the enormous members as she was pumped full of sizzling hot seed. It wasn’t long before she was filled to maximum capacity, but things had only just started.
Copious amounts of potent semen continued to flow into the eccentric woman’s baby chamber, and not a single drop was allowed to escape from the sheer tight grip she had around Mei’s penises. The influx of volume never seemed to end however, causing Shiki’s womb to inflate to accommodate it all.
Groaning as she fired one last blast inside of her delirious lover, Mei crashed down against Shiki, keeping herself buried to the base to ensure that nothing spilled out. She was quite satisfied with what she had done, and she was positive that she had knocked up her girlfriend from this single creampie.
Shiki’s stomach was deformed, swollen up and protruding from her body as she already looked pregnant with a baby bump. It was a sign of just how much love she had been pumped full of by Mei, that there had to be millions upon millions of sperm swimming around inside of her.
She could hardly comprehend what had happened. It all blurred together at some point, but Shiki knew without a shadow of a doubt that Mei was a force to be reckoned with. She always wanted to be the bottom, to be submissive and ordered around in the bedroom, but it was clear that she was more adept at being dominant.
They were both well spent, neither of them having anticipated how addictive or intense bareback babymaking sex could be, yet as they gazed lustfully into one another’s eyes, they knew that this was utter perfection. The pair were both dripping with sweat, and their bodies were shivering from the aftermath of their shared orgasms.
“I-I love you, Shiki.”
“I wuv you too, Mei.”
********************************
Months had passed since Shiki decided to be a test subject for her own project, and she was still working on it day in and day out in an attempt to see to it that she perfected the formula. She was more determined than ever to see to it that this was a huge success, if only to please her girlfriend.
“Shiki, how are you doing?” Stepping into the lab, Mei set down the cup of jasmine tea with a smile on her face, knowing that her eccentric partner was hard at work. She was even more supportive of Shiki’s efforts, believing that this was one way to see to it that lesbian couples could have children of their own without needing to resort to a donor.
Spinning around on her stool, Shiki eyed the redhead up, noticing a prominent baby bump sticking out from underneath her clothes. Knowing that it was her child, she nodded her head with a satisfied grin before explaining, “I think I’m making good progress. Don’t worry so much, Mei. I’ve told you everyday for the last week that things are fine.”
“Shouldn’t I be the one to tell you that? Shiki, you’re carrying twins. You don’t want to stress them out while working in the lab everyday, do you?” Putting her arms on her hips, Mei was flattered that her girlfriend was worried about her, but she wasn’t the one working long hours all week.
Rising to her feet, Shiki wrapped an arm around the redhead’s waist and pulled her closer, rubbing their bellies together as the both of them were pregnant. Their little experimentation in the bedroom was a complete success, even if the very drug that they were testing out was far from perfect.
“You’re cute when you’re worried, Mei.”
“D-Don’t just say that so casually!”
The two were far from perfect themselves, but they were determined to start a family together, and now that they were carrying one another’s children, they knew that this was only the beginning of a new chapter in their lives together.
