Hipposagainstleopards
Notes: A slight suggestion by a certain nurse of an unusual way to procreate and a reveal about Saeko and Rei leads to an interesting choice for you.
(This is a CYOA.)
--- Chapter 1: Introduction ---
As you might have noticed, this fic has the Choose Your Own Adventure tag which means that you can choose to read through every route or pick the one you're interested in with Double (Saeko and Rei) being the longest and having urethral birth. The list of choices is here-
Chapter 2: Saeko Route
Chapter 3: Rei Route
Chapter 4: Double Route
I left the POV identity as ambigous as possible here with just that they've been in the main HOTD group for a while and are close to Saeko and Rei meaning that this can be considered an AU fic with the reader insert.
If you want an official answer, the futa choice is Shizuka herself who was actually the one who found out about docking and ball impregnation recently, plus she has the perfect assets to be a mother and just add her own formidable cock and balls, and the male choice is Takashi who might get more than he bargained for with either of his side-chicks and has the perfect body type for this, getting his boys impregnated by his crushes is definitely going to be an experience.
--- Chapter 2: Saeko Route ---
"So...you went with me? Interesting choice..." Saeko Busujima simply walked behind you dutifully before leaving her katana by the teacher's desk, it was an interesting choice to make another high school your group's base after the long trip throughout the city but it was the best option and as you sat on the desk, you noticed her lean in with a pleased smile. "I do hope you don't think I'm lacking in assets or you'll wind up being quite shocked..." The Kendo club captain seemed to think that you were underestimating her, whatever the case, you knew the purple-haired girl looking right into your eyes with her blue irises was beginning to lift her black skirt up and you could notice her green panty was on top of something quite massive.
Saeko's green and white uniform was opened up with her other hand still covered in a black glove while the other one was pulling the foreskin off an impressively girthy cock, still a fairly lengthy secondary sword for the Kendo club captain that was easily lifting her skirt on its own as her fairly big breasts jiggled profusely while she tapped her pink tip against your bulge. "Do you still want to try this?" Busujima's pink tits were erect on her bust and her huge balls were beginning to strain her green panty which only made you nod as you noticed her other hand no longer had a glove on, she yanked your legwear down and licked her lips at the sight, clearly she had found her preferred sheath and began to push her cockhead against your own.
Saeko let out a low moan as she began to lean in further with her smile growing on her face while her wide hips continued their thrusting, holding your cock in one hand to steady it before she got fully into your urethra that leaked precum as a form of natural lube which enabled her to slowly get her swollen tip into your member and only looked into your eyes as your cockhead got noticeably engorged. "Hah, your cock is such a good fit..." Busujima pumped her hips into your urethral tract to get more of her futahood into your dick and her grin got far more degenerate as she felt how tightly stretched your penile walls were around her and yet, you clung to her without any complaints despite the bulge in your own reproductive organ as she got deeper into you.
"Let me connect in the most intimate way with you...hah, this really feels better than what fucking my pussy would feel like?" Saeko was practically using your member as a sheath with her wide hips pumping her cock inside the warm embrace of your penile walls slowly and deliberately, clearly not wanting to rush fucking your tight urethra with a pleased smile and her gloved hand practically pinning yours to the desk while she treated your reproductive organ as little more than a hole to be used. The purple-haired Kendo club captain could only keep thrusting in your meat with Busujima's girthy shaft visibly stuffing your urethra in full-view, a move you felt was deliberate on her part as she cried out lustfully and her naked hand was planting your own palm against your reproductive organ while she used it.
"It really does feel perfect...I can't stop until I've emptied at least once into your family jewels..." Saeko kept slamming into your urethral tract again and again, battering aside your penile walls with her potent futahood as your dick clung onto her like a sheath, her rack bounced with each movement into you and you could see her letting out her cries more liberally before she got a hungry look in her eyes and pounced on your face. You couldn't even focus on anything but her blue eyes staring into yours as her lips wrapped around yours and how it felt to have only a few inches of your penile walls not get utterly stretched out by her member, your cock feeling waves of pleasure from how she was pumping into it with even more vigor than before.
"Feels like I'm going to empty them completely into your family jewels with how much you're clinging to me...heh, you do know I didn't masturbate once before this just to save up for you?" The purple-haired Kendo captain was really going to go all-out on this 'repopulating experiment', it seemed; Saeko got right back to kissing you once again, this time with her tongue wrapped around yours while she got her impressive meat hilted in your shaft and had as much fun pumping her plump hips forwards even more then despite being fully in you. Busujima clearly had more than a few screws loose but you couldn't complain when her tits were pressing up against your chest before she pulled her face away from yours and began to thrust into your urethra even more intensely, noticing how she was running both her hand and yours along your dick as she filled it up with her futahood and you could feel her throbbing deep in you.
"Your cock is quite the sheath...I think I'll hilt soon to deliver some heirs to your family jewels." Saeko's massive balls were clinging to her groin tightly in the green panty containing them as it threatened to snap, the purple-haired girl only went into even more intense thrusts that when combined with her cock getting even more engorged did a great job of absolutely stuffing your member's urethra and penile walls. While those parts of your shaft were stretched to their limit, the outline of Busujima's meat was clearly visible in your reproductive organ and the Kendo club captain's childbearing hips pumped frantically as her throbbing got more rhythmic, her ample rack bouncing considerably with her movements.
You could only brace yourself on the desk as your backside leaned against it, watching Saeko hilt her futahood repeatedly in your dick and then pull back just to repeat the same intense slamming movements with an absolutely blissful smile on her lips and her blue eyes focusing on you for the time being as she moaned loudly in your ears. "Oh?! I'm cumming!" Busujima hadn't even realized she was leaking precum into your urethral tract until her balls were frantically pulsing to let a flood of sperm out of her loins halfway in your cock as her girthy member throbbed relentlessly in your tight, warm penile walls trying to close on her in an attempt to get back to their original positions.
Saeko was certainly getting your prostate wet although it was more intense warmth as her cum pushed through it in moments and then flowed down through your opening vas deferens, taking advantage of your own climax to visibly swell the start of your reproductive tubing next to your shaft as her meat pumped even more into you. "Mmm... Ahh..." Busujima couldn't even form words as she stared in your eyes before looking down to your pair of testicles in anticipation, it didn't take long for your epididymes to engorge past the point of blocking access to your orbs and you could see how the sack immediately grew taut with many veins visibly twitching along the skin due to the sudden and intense expansion.
It felt like you hardly even had a couple moments before your babymakers were obscenely bloated with Saeko's seed that she'd been backing up in her somewhat-diminished looking testes, now going far enough over the sides to cover up the top of your legs and reaching up to your tip in length after they were in mid-bounce. "Such a nice-looking pair of family jewels...I really hope they got pregnant..." Deep inside your balls, the massive amounts of virile Busujima sperm quickly began pressing up against your fertile swimmers and forced themselves into countless cell membranes, ensuring that with how heavy and intensely pulsing they were, you were going to get pregnant in this way after all without a doubt.
Especially as her rich swordmaster bloodline nuclei got straight to dividing, trading, and mixing traits and DNA for the future offspring, Saeko's seed had clearly made your loins' new purpose clear, a pair of healthy womb sacks that would be only getting even more heavy hanging below your dick with the coming months and her very clear intent to continue using you. "I did impregnate you, didn't I? Good, let's make some more." Busujima didn't even ask before she started thrusting again into your cock, thankfully your penile walls were getting used to the immense girth of her member even though your urethra would be gaping profusely when she eventually pulled out but the tingling warmth in your balls as your new sperm-eggs implanted in the walls and bottom of your septa seemed to almost lull you into it.
After all, the Kendo club captain couldn't let her new favorite sheath go after just one round...

Chapter Text
"Of course, I knew you'd go with me! We've known each other for so long!" Rei Miyamoto had a wide grin on her face as she followed behind you with a skip in her step, her brown eyes focused entirely on the back of your head while you entered the classroom and promptly sat down only for the Sojutsu club member to get right on top of you before pushing you backfirst on the teacher's desk. "You think I wouldn't take full advantage of this opportunity?" Miyamoto leaned in to passionately kiss you while you could feel her undoing your clothing and you reached under her green and white plaid skirt to feel up a shaft you could only surmise as absolutely akin to a spear on it's own with how long it was and yet extremely firm but it did have only moderate girth, you clearly felt it twitch excitedly in your grasp.
"Nice, isn't it? What about yours?" Rei pulled away from your lips and tongue to see your own formidable meat although her pair of balls hung low and were thicker than yours while covered by a white panty, you outclassed her in width and she seemed taken aback for a moment before her cock forced her skirt up on it's own and she tore open her already straining uniform top to let her massive breasts flop in your face. The green and white uniform opened up to let Miyamoto's slim belly press up against your own stomach soon afterwards and she laid her tits on your chest while you could feel her cockhead pushing against your tip, trying to get inside while she locked lips with you again and you could feel her putting a surprising amount of force into the thrusts of her wide hips.
"Come on, it has to go into you..." The brunette kept trying to get her shaft into your meat while you could only see her sticking her tongue out with Rei's brown eyes seeming to only be filled with desire for you at the moment, she finally got the opening she desired when your urethera leaked a bit of precum and her reproductive organ slid right in. Miyamoto's futahood actually went down all the way into your dick, leaving a few inches exposed but she moaned loudly as you could feel her swollen tip lodge in your prostate and the comfortable fullness of her length in your penile walls, stretching them out a moderate amount which resulted in their warmth clinging tightly to her form and eliciting a lewd chuckle from her when she recovered.
"Ah, you really wanted this badly, huh? I'll fuck your cockpussy with my spear of a dick every day from now on!" Rei looked down at you with a wide grin as she slammed her groin down onto your cock, her member frantically thrusting into your urethra and pulling back out as she docked with your reproductive organ, she kept going at your hole with her spear as fast as she could move her hips fully intending to impregnate your balls and held your hands down on the desk. It was clear that either way Miyamoto had no intentions of letting up on your meat with her shaft and you could feel her cockhead ram your vas deferens each time she hilted herself with a soft moan and her tongue hanging out for a moment as she lifted herself up just enough to watch her reproductive organ stuff itself in your reproductive tract.
"Looks nice, huh? But it feels wonderful in your cock and it must be even more pleasant for you..." The Sojutsu club member got right back to pressing her body against your own and made sure her plump bust was squishing against your own chest while her pelvis kept pumping her futahood all the way into your dick and pulled back to only her tip remaining in you before Rei slammed back down. Miyamoto's pace was slow but every movement was deliberate and left your entire member feeling trembles of pleasure from where her cock pushed aside your penile walls to get back to your prostate that soon began to almost suckle on it with a tight grip to keep her pressed right up against your vas deferens.
"I'm going to be honest, I've not been saving up but, hah, I think your cock will just milk it all right out of me!" Rei threw in some moments of lifting her body up so you could see her meat thoroughly lodged in your surprisingly stuffed urethra along with taking her time in kissing your lips and wrapping her tongue around your tasting organ while she thrusted at the same pace despite her brief interruptions from pushing her body onto yours. The brunette girl soon began to moan and cry out even louder as you felt Miyamoto's futahood starting to swell up in your shaft and you could feel her just rubbing against the opening to your reproductive tubing when your prostate latched onto her, she couldn't even maintain a grin anymore, instead it got replaced by open-mouthed panting.
The Sojutsu club member's brown eyes kept looking at your face or your stretched urethra while you noticed her balls weren't slapping against your shaft as frequently as before, rather they were now clinging to her pelvis as Rei increased the speed of her thrusts into your cock with her long member pushing past your penile walls with ease. "I'm going to cum inside you...then we'll see if you can be a mommy..." Miyamoto's tongue hanged out as she put her all into making sure you could feel every impact with her tip into your prostate, your meat feeling waves of pleasure from how her shaft kept ramming into your vas deferens and then pulling back while she now only pressed her body against you, fully commited to trying to impregnate you.
"I really hope this one doesn't break..." Rei muttered as her white panty groaned with her family jewels swelling and began to even start wrapping her tongue around yours throughout the process, her futahood swelling to stuff your urethral tract further and twitching more by the moment until she finally hilted herself in your dick one last time. "Hah...I'm cumming!" The brunette Sojutsu club member practically moaned out as Miyamoto's cockhead finally opened up your vas deferens after the last push and now began to unload directly into your reproductive tubes, with how much it was swelling up in your prostate, it wasn't going to pull out anytime soon and her member throbbed without pause in your cock.
"Ah! My balls and my spear...they just want to keep using your own pair and cock..." The brunette girl could only let out one continous stream of lewd cries while her large balls pulsed rapidly to send out the most cum they'd ever let out into your own testes, her shaft's tip grinding into your meat's base with the desire to breed you growing with Rei's brown eyes full of lust and your vas deferens poking two inches above the surface next to your reproductive organ. Miyamoto's potent warmth easily flowed down your reproductive tubing and your epididymes practically just opened up for her, the sack encasing your testes stretching to accomodate the slow but steady growth your pair was experiencing with a couple veins swelling up to pump more blood to the orbs.
"Well now, looks like we're even more of a matching pair. You might be carrying something extra though!" Rei could only smile as she lifted her body off of yours, her huge breasts seeming reluctant to leave your chest while you got to see just how low your loins were hanging, they were reaching your knees already and filled up the space between your legs while you could feel warmth spreading through them. Within your testicles, Miyamoto sperm swarmed your own swimmers and quickly proved their virility as they penetrated deep into the cell membranes of countless fertile seedbeds called your own future offspring, at least they were getting used to kickstart conception within your own pair.
"Feels good in them, huh? I hope a lot of the Miyamoto seed takes in you..." Rei's family jewels seemed even lighter than before and your own balls seemed fuller than ever, dozens of new sperm-eggs attaching to the septa inside your still quivering womb sacks by the second and with how many traits the nuclei mixing had resulting in already, the combination of DNA would cause a very heavy pregnancy. But then, a look of concern crossed over Miyamoto's face as she tried to pull out, the brunette Sojustsu club member's tip simply refusing to leave your prostate where it was firmly lodged in to your tightest and most warm embrace, you could feel her member starting to swell and throb in a familiar manner while her brown eyes looked at you as she pressed her fat tits against your chest again.
"Fine, if you're that desperate to be my wife, might as well make you a mother to a couple Miyamoto generations!"
--- Chapter 4: Double Route ---
"Both of us?! Really, are you serious?" "Isn't that a bit much for your shaft?" Rei Miyamoto shouting in disbelief and Saeko Busujima whispering her concerns as they showed off their respective futahoods to your cock certainly emphasized the point, your member would be getting extremely stretched out from that lengthy spear and girthy sword the two girls had respectively. "You won't listen, will you? Can't you just have one of us fuck your cock?" "I admire your bravery but your prized reproductive organs will be..." The brunette Sojutsu practicer and purple-haired Kendo captain kept voicing their negative opinions before deciding to start getting their knees on the desk with the black leggings resting next to your bare legs while Miyamoto's long shaft and Busujima's thick meat measured next to your own reproductive organ.
"You're going to get pregnant with both my kids and her own runts, do you have any idea how heavy your balls will be?" "I don't mind Busjima and Miyamoto offspring gestating in your family jewels at the same time but..." The brunette and purple-haired girls kept at it until you pressed your cockhead forwards against their tips when they weren't expecting it, Rei and Saeko both letting out a moan as their dicks rubbed against each other while your urethra leaked precum and you soon saw a mischevious grin go across both of their faces. "If you want your cock and balls utterly dominated that badly..." "Let us alleviate the emptiness of not having any children to grow in your womb sacks..." "AH!" Miyamoto and Busujima soon began to press down themselves and let out a loud cry in unison when their cocks managed to enter halfway in your urethral tract, your member getting a very obvious bulge thanks to the Kendo captain and you could feel the Sojutsu practicer's tip almost reaching your prostate already.
Saeko and Rei soon looked at each other with a wide smirk along with their bright blushes and began to thrust their childbearing hips into your penile walls, the purple-haired girl's meat pushing them far apart from each other on the right and the brunette poking a couple inches into your prostate repeatedly on the left. "What a potent member, it can take both of us fairly well." "I've got to hand it to you, your cockpussy isn't bad at all!" Busujima and Miyamoto commented on your dick while their futahoods were currently fucking your urethral tract without pause, your reproductive organ soon feeling overwhelming pleasure from the duo competing or perhaps cooperating to fill your own balls first with their much bigger orbs, even if you didn't get pregnant, your pair would be getting huge.
You could see Saeko and Rei were having some problems with pumping into your urethral tract however, the brunette could hardly maintain the rapid speed she wanted with the massive girth in her way and the purple-haired girl kept stopping inadverdently in the middle of a slow movement while a fairly long cock rubbed against her, your member being stuffed to capacity. "Not so rough, Rei! We need to make this pleasant for them..." "How is this going to be pleasant with your oversized cock in the way?!" Still the Kendo captain and Sojutsu practicer were making your entire groin flare up with pleasure, Busujima's meat and Miyamoto's shaft making for a surprisingly good combo and the fact that you got to see two nice big pairs of breasts bouncing with each thrust and the wide hips trying to stuff their reproductive organs deeper into you only made it better.
Rei soon got even more impatient with her childbearing hips pumping faster as you could feel her swelling and Saeko kept on hilting herself in you while you could feel her futahood throb intensely, both of them were about ready to unload their ample balls in your dick and then into your own pair as your penile walls and vas deferens seemed to be eagerly opening up. You noticed the brunette was now reaching her hand over to squeeze the purple-haired girl's ass and got a loud moan out of her as her eyes closed, the cheeky grin Miyamoto had was soon replaced with her mouth hanging open while a glove groped her tits but you noticed one of the duo's palms were firmly planted on your member as they tried to steady their cock's thrusting with the new stimulation.
"You really think you can outmatch me with that fat cock? It's almost as large as your ass!" "I do not mean to fight over them but your breasts would do far better at pleasing someone than your thin shaft." It was clear that Rei and Saeko now had gotten fully into the mood to try to claim you completely for one of their bloodlines but you couldn't pick one when they were pumping into you so recklessly with no desire but to breed and your urethral tract was all too eager to suck down their shaft and meat some more. Miyamoto and Busujima did make one mistake however as they squeezed their hands too tightly in one final groping of their rival's assets, resulting in the Sojutsu practicer and Kendo captain both slamming their entire futahoods in your dick as their balls audibly churned and visibly pulsed with the virile contents of their balls being fully ready to release into you.
"I'm cumming!" Saeko and Rei cried out in unison as their tongues hanged out and their eyes rolled up, an utter deluge of cum slipping right through your prostate and rapidly moving down your reproductive tubing to fill up the epididymes to the point that you could see them bulging out where they attached to your groin and your vas deferens didn't do any better. Both of them were easily a couple inches more swollen than they should be and were easily noticeable thanks to the fact that they were quivering with how much warm sperm was traveling down them and building up, not to mention, the mind-numbingly pleasant heat and that was before the flow got into your testes.
To say that your loins got engorged was an understatement, they practically tripled in size in mere moments as the Busujima and Miyamoto family jewels completely emptied in them and you could see them completely cover up your legs and reach your feet before stopping as they pulsed with foreign warmth and there were plenty of throbbing veins pumping blood to the extremely taut sack. "Oh my, we emptied everything into them...what a nice pair of womb sacks you have now." "You know, maybe we can share this cockpussy...it's really eager for both our sperm!" Your epididymes looked like large bulbs clinging tightly to your pelvis while topping the massive and heavy orbs that were very clearly getting pregnant with how much they trembled as Saeko and Rei's seed within them got to reproducing, your vas deferens looking about as half as girthy as your cock next to them.
Saeko and Rei's seed had been packed into your balls with the full contents of each girls' pair and your own swimmers' cell membranes gave in under the pressure, virile futa sperm from one of the futas swarming inside each fertile swimmer and rapidly trading DNA with your own nuclei, ensuring the creation of new life in your now thoroughly filled testicles in an apocalyptic world. "We definitely have to get married now..." "That was fun to force your balls to bear offspring." Your pair got less tense as the Sojutsu practicer and Kendo captain's future babies began to compact into your own potential offspring, the nuclei mixing and dividing inside them as your cell membranes closed up to keep the pairings close together, your testes had been impregnated with many different offspring put in you by the two girls.
"Don't push yourself alright, that's more than enough that you've done for us." "A future mother shouldn't exert themselves too much and I'm glad to call half of those new young my own." Miyamoto and Busujima smiled happily and their plump breasts jiggled as they pulled out of your still tingling member and the urethral walls they stretched out while your extremely heavy and knocked-up balls finally settled down with the stretched sack's many engorged veins throbbing sporadically in response to literally becoming babymakers, still feeling full of warmth as your family jewels became the places where both their bloodlines would flourish once more and you would be the one gestating them before giving birth through the same urethra now stretched out significantly from the rough reproduction you agreed to. Saeko and Rei had trouble getting their skirts to go back down on their slowly softening futahoods and their tits were still erect just looking at your conquered reproductive organs, your member remaining pointing towards the ceiling with a still clenching urethral cockpussy and womb sacks that were beginning to soften up as your septa began to host several sperm eggs that would gestate the girls' young along them deep in your balls while you fell unconscious from a pleasant exhaustion.
It certainly wasn't bad knowing that you'd be contributing a significant amount of new human beings to the genepool even with the dead rising from your family jewels stuffed full of Kendo captain and Sojutsu club girl sperm, their virile babymakers continuing their families by packing your pair full of virile swimmers pushed deep inside each potential cell and with a good mix of DNA from you and them. You hoped you'd make a good mother and that your babymakers would gift Busujima and Miyamoto with many kids just as cute as them, in fact, you would come to realize just how much more efficient your pair being used to bear healthy children was than using their wombs very soon when they got even bigger over your legs and pulsed happily with how many you'd be carrying...
It had been almost nine months since Saeko and Rei impregnated your balls, the fact that they rested on your legs now, hung down to your feet, and jutted out to almost your tip made covering yourself up with legwear difficult but it was surprisingly easy to move around with them albeit the occasional kicks of the babies almost done gestating inside them tended to make you dazed with pleasure. It was almost like a massage inside your heavy testicles and your cock was always somewhat erect, now having the urethra gaping open a couple inches from all the times they used you but as you laid on the same teacher's desk they knocked you up on, you suddenly felt something extremely pleasurable as Miyamoto and Busujima moved off the walls to your sides.
"Oh, they're definitely kicking alright! That reminds me, shouldn't it be-" "Well, the gestation period seems to be the same but your family jewels seem far more productive than our wombs could ever hope to be." "Hey, deliver them and we'll let you fuck our pussies unless..." Rei and Saeko whispered as their bare hands ran along your massive balls now having little bumps all over and then fading, the offspring within kicking with fervor as they got ready to come out of you and your stretched urethra eagerly leaked precum in anticipation, honestly, being bred by them was probably the best thing to happen yet. But you could feel your orbs clinging upwards to your groin even more tightly and visibly throbbing as you felt two very large shapes making their way up through your bulbous epididymes, the opening to your reproductive tubing from the testes letting the babies up into your now thoroughly widened vas deferens.
The thoroughly swollen epididymes and vas deferens combo served extremely well at pushing a new child out through your testicles and up through your reproductive tubing before one hung back for a couple moments to let their sibling travel up through your frantically twitching member's penile walls. While this did overload your mind with lustful love towards the now practically beaming Busujima and Miyamoto, it did make your dick even more visibly engorged when they went through it before going through your urethra and making it stretch to accomodate the new life you had been forming in your testes.
This wasn't to say that your epididiymes and vas deferens weren't getting equally swollen further by the children being pushed through them by your womb sacks' finished gestational period, Saeko and Rei quickly grabbing the new young as soon as they popped out and placing them next to the place where they instinctively sought nourishment. Your chest was now two plump milkjugs spurting out milk and your whole body heaved as it felt like your loins and meat were delivering a good dozen babies with the vast majority of them having to be put in cribs and given a bottle by their futa mommies, now working together fully to care for the new life you brought into this world.
It felt like your head spun for a couple minutes before you came to again and realized that Busujima and Miyamoto were now smiling widely next to your face, your womb sacks and cockpussy finally calming down next to your childbearing hips and seeming to relax but you knew exactly what you wanted from those two again as the new babies were brought out of the room and into the makeshift nursery.
"More...."
"Of course, Miyamoto mommy, you really outdid yourself and you deserve a reward..."
"You want to stay this heavy with Busujima young, don't you? Good, let's make you pregnant again...."
You noticed the Miyamoto shaft and Busujima meat rising up above their respective family jewels as they got back on the desk to repeat the process and you hoped they'd never stop.
