Bad End: Last Cumdump of Humanity
Hipposagainstleopards

Chapter 1: Chaos Tide Ushiwakamaru & Tiamat PoV

Few Singularities had as much potential for a disastrous ending as Babylonia and this was certainly a colossal catastrophe, getting stuck in Chaos Tide mud while your Servants and allies got dumped in the sludge as well. Needless to say you were pretty much a sitting duck for the corrupted Servant responsible for your crash landing and now approaching you as the Tide practically solidified around your limbs, preventing escape or Command Seal use. You did have your torso and head free at least...

"Hey Ushi, back at Chaldea we actually get along quite well..." That was the best you had to salvage this mess.

“I’m sure we have.” Said the corrupted Rider, “And we’re still going to get along quite well, albeit in a different manner~”

"So, we're still good? That's a relief because I was afraid I was going to get my head cut off or something!" Being the Last Master of Humanity was kinda nice with all the Servant girls wanting mana transfers but the constant fear of death during Singularities was a bummer.

"Uh, what are you planning on doing then?"

“You’ll see~” Ushi massaged the Master’s crotch, “Tell me, how big are you~?”

"A bit extensively modified and reinforced with magecraft, Chaldea Ushi really likes it..." You got a bulge in your legwear even though you had a bad feeling about that smile Ushiwakamura had, even though her sword was currently sheathed…

“And your balls~?” Ushi asked, “Surely they have to be big, big and productive to make sure any girls you lay with are left filled and satisfied~” She started to slowly fish out the cock, still smiling.

"I mean, my dick is fairly big but I don't see the point in expanding my mana producers...helps keep Kiyohime and Serenity off me all night..." You muttered the last bit even as you felt your balls begin tensing up, eager to fuck another Servant even in this tense situation. Was corrupted Ushi as good a cocksleeve as regular Ushi?

Ushi pouted at the words and the sight of the size of the balls, not even a handful each.

“That’s a shame,” she lamented, “But with Mother’s help, the lacking size will be a thing of the past.”

"You mean Tiamat?!" Now even though she was a Beast, the thought of fucking that sexy MILF was nice and instantly made you hard, easily within the ballpark of two feet and quite meaty for a good width. But didn't she say lacking?

“The length is good…” Ushi stroked the shaft a few times, “Sure to be a comfy fit, but these…” She juggled the Master’s balls in one hand.

“Lacking… so lacking… even if Mother’s gift to me will surely fix that…”

"What gift do you mean..." Your voice trailed off as you thought you saw the hint of another sword hidden beneath that black panty and you noticed her gray nipples getting erect at you noticing.

“Well, no time like the present to fix that little deficiency~” Ushi smirked as she freed the bitchbreaker Tiamat had granted her, the heavy, bloated nuts sloshing audibly.

You couldn't even say a word in your shock, not once as Chaldea's only Master did you think you would face a threat like this, the Lion King and Solomon were at least physical threats but this... Ushi could rival your mage bloodline continuer and you gulped as you felt the Tide push your head and torso forward while maintaining that steely grip on your limbs.

“Our shafts match each other rather well, don’t you think~?” Ushi giggled, “And I’m sure now you truly understand what I meant about you being lacking in one area~” She angled her cock under the Master’s ballsack and used the corrupted shaft to lift them easily.

"Yeah, you definitely have me beat there but why are you so interested in my balls?" Seeing that gray tip showing off just how small your mage family jewels were compared to those massive corrupted testicles churning and tensing up in front of you made you quite conscious of your ball size for the first time.

“Well, you’re going to be helping Mother birth a new iteration of humanity.” Ushi explained, “If it weren’t for the blessings Mother gave me, these pitiful orbs you call your balls would be useless for that.”

"Birth? My cock isn't a pussy and my balls aren't exactly wombs, especially for those nasty Lahmu!" Yeah, this was quickly going from bad to worse as you shouted and struggled to no effect.

“Not yet they aren’t~” Ushi giggled, “Or are you just saying that because you’re insecure that they’ll be up to the task~?” She giggled some more.

“I told Mother that she could use me for it, she certainly gave me properly sized equipment for it,” she hefted one of her balls with a hand, before dropping it and letting it bounce and slosh, “But she was insistent that it be you, so be grateful that these absolutely pathetic things are finally going to be useful for once~” the corrupted Rider mockingly tickled the Master’s sack with a finger.

"Can't we use your dick?" You'd seen enough doujins to know where this was going and you certainly didn't like it, where the hell was the Chaldea rayshift staff?! Suddenly some hope arrived after a couple tense moments as your commlink opened up.

"Well, you seem to be in a rather nasty situation, Master."

"Get me out of here, da Vinci!"

"I would love to but that Chaos Tide, it's got you held fast." Crap, Ushi seemed to know that with her wide malicious smile as your balls jiggled from her finger tracing the veins on it.

“Like I said, I wanted to.” Ushi sighed, “But Mother really wants it to be you for whatever reason…” she continued tickling the Master’s balls, eyeing them like she was contemplating whether or not to crush them.

"A~" A booming noise rang out somewhere far away and you almost heard something that sounded like Gorgon moaning?!

"You see, this Chaos Tide is really remarkable stuff..."

"I don't care about the science of it!"

"Point is, it's locked your body into this Singularity so unless you or your Servants can get out..." Well, at least the corrupted Rider seemed to be less menacing from her Mother interrupting but you certainly did not enjoy da Vinci telling you just how literally screwed you were.

“Tell you what~” Ushi leaned in, a vicious grin on her face, “How about if you apologize to me that I need to waste Mother’s gifts to me on allowing your inferior balls to be the ones to birth the new humanity, I’ll go… relatively gentle~?”

"Why exactly do you have to fuck me if she produces Lahmu? You're a bunch of Chaos Tide clones!" You certainly didn't care what Ushi said to you, you had to go against her or Uruk was fucked worse than you.

"I think I might get it, Tiamat sees you as attractive and a trophy from Humanity while Ushi-" Da Vinci was rudely interrupted by Ushiwakamura explaining the details herself.

“If I had to use an analogy…” Ushi sighed, “I’m the plow used to till the fields and prepare them for Mother to actually plant the seeds. I’ll also be getting you to a state where you can more easily accept her size.”

“Guess we shouldn’t be surprised the primordial Mother Goddess would be even bigger…” Da Vinci noted.

“That aside,” Ushi leaned in close to glare right into the Master’s eyes, “I may not be allowed to take your head, seeing as Mother needs you alive for her purposes, but there are other parts I can cut off or cut out without damaging your ability to produce young. So unless you don’t mind losing things like your limbs and whatnot. Let’s. Hear it.”

"No, I'm not bending to you. My limbs are already pretty much useless so what are you going to do, fuck me rough enough to break my mind?" Alright, maybe that sarcasm was too much even though you did feel a growing sense of fear but your Servants, the citizens of Uruk, and Chaldea were counting on you! Even though you just heard the Caster speak in your ear as the corrupted Rider's eyes narrowed as you started talking and then widened.

"Can you not anger the psychotic Servant, Master?! You're literally just being kept as an ironic birthing place for a Beast to destroy humanity by knocking up the Last Master of Humanity with those ugly Lahmu!" Da Vinci shouted.

“I could always do that.” Ushi admitted, “But then I wouldn’t exactly get what I want if you’re reduced to a babbling idiot. And if not your limbs, maybe your eyes and ears? I could always just cut you, give you a new wound every day until all you know is pain.”

"Fine, show me your nice side and we'll see if it's better than Chaldea Ushi-"

"There's a start."

"Shut up." Da Vinci was a genius but sometimes she got annoying, this was one of those times as you had a Chaos Tide-corrupted Ushiwakamura standing over you with her cock and balls out, you didn't need her to remind you to stall for time. "Please...use my urethra as a pussy for that fat cock?"

Ushi continued to glare.

“That’s not any sort of apology I’m familiar with.” She said.

"I'm sorry you have to waste Tiamama's gifts on the Last Master of Humanity, will fucking my member make you feel better about that?" You stared back at her intensely as you choked out the words.

“I believe I explicitly said.” Ushi growled, “That I wanted an apology for the fact that your inferior balls are being used to birth the new humanity.” The corrupted Servant emphasized her point by lightly smacking the Master’s balls with her shaft.

“Feel free to get creative.” She sneered.

"I'm sorry Tiamat is really kinky and wants to put her version of Humanity in the Last Master's balls to prove her point when your pair looks like they could get twice as many Lahmu in them at least." That ball smack surprisingly hurt as you grimaced and tried to do anything but look intimidated by the Rider. "I mean, look at them? How much of a Chaos Tide do you have backed up while my mana containers are emptied daily?"

Ushi grinned.

“Much better~” she purred, “Keep going~ I want to hear you talk aaalllllll about how pathetic these things are, how ashamed you are about how small they are, about how every female Servant in Chaldea wouldn’t give you a second glance in favor of worshipping the glorious cumtanks Mother gave me~”

“They actually do look rather tasty…” Da Vinci muttered, not realizing she was heard.

"Oh come on, you think anyone looks good!"

"I can't help that my tastes are varied."

"I'm sure any Servant I have, even Raikou wouldn't be able to resist throwing themselves at you if they saw that pair. Chaldea Ushi would probably agree that her Master's balls are only fit to be bred compared to that glorious pair!" You kept it up even as that damn Caster drooled, what the hell were the goddesses and Mash doing? Did Tiamat start fucking them all?!

"You make me feel like the only way I can continue my mage line is by having your kids into every little sperm cell I have and gestating within each and every crevice of my septa, just to show how virile you really are. Make me a mother to the Yoshitsune bloodline...knock up my mage family jewels so they're nice and heavy like yours..." You lifted your cock and balls a surprising amount just to please Ushi, the Chaos Tide letting up a bit to allow that.

“Nice and heavy you say~?” Ushi giggled, pleased at the Master’s submission, “Let’s see just how heavy they are~” She moved and placed her cumtanks on the Master’s shaft.

“Go ahead and try to do what I did to you earlier, try to lift my balls with just your cock~”

You couldn't even make those massive orbs budge an inch, all you could feel was them churning and sloshing against your shaft, the sensation being slightly hypnotic as they pulsed against your cock intermittently.

"Fuck, make my balls pregnant~"

“Getting kinda into it, I see?” Asked Da Vinci, “Not that I blame you, fuck I want those balls on my face…”

“That’s the plan, unfortunately.” Ushi sighed at the Master’s words, “Although~” she smirked.

“What, exactly, was that?” She asked mockingly, “Did you even try~? It’s easy, watch~” She moved her shaft under the Master’s balls and once again effortlessly lifted them.

"Just fill them up with your swimmers...knock my pair up so that all I have is a pair of womb sacks that can only gestate offspring, not produce them~" You couldn't believe what you were saying, how would your kouhai or any other Servant react to you saying that.

"They're too potent for me to move..."

“They really are such small, pitiful looking things, aren’t they~?” Ushi continued to mock, bobbing her cock up and down enough that she was practically juggling the Master’s balls on her cock, laughing at the way she so easily made the orbs jump and bounce.

They honestly looked like grapes at best compared to the watermelon-sized pair the Rider had but her teasing was unfortunately turning you on more than Chaldea Ushi ever had.

"Make my cock into your sheath~..."

“Are we even certain it’ll work~?” Ushi tapped her chin exaggeratedly, “I mean, they’re so pathetic and minuscule. For all we know, even Mother’s greatness wouldn’t be enough to make those impotent little marbles capable of breeding…”

"I want it...I want your sperm knocking mine up to the last~..." You practically panted those last words out, your erection growing painfully stiff with no release as you waited for either the Rider to use you or your Servants to help.

“Let’s just try this one more time~” Ushi smirked as she rested her churning balls on the Master’s shaft again, “Surely you can at least make them shift even a little bit~?

Well, now with how rock-hard your meat was, at least you made them shift into your face and rest there for a moment as you heard the Rider chuckling darkly at your expense as you felt how warm they were and how much they were churning with her unused seed.

It was like they were trying to get you into the mood to only be bred like a little bitch.

“Tricked you~” the corrupted Servant giggled, revealing she had gone on her tiptoes, only making it look like the Master had succeeded, “Did you really think it’d be that easy~?” She lowered herself back down, letting the cumtanks weigh down the Master’s shaft and making the Master truly appreciate how heavy they were.

“Until you can move them~” Ushi taunted, “I won’t breed you~”

“You’re never gonna get bred…” Da Vinci moaned in disappointment, “No way you’ll be able to move such godly nuts…”

"You really want to make me work this badly?" You put a colossal amount of effort into lifting those huge cumtanks and actually managed to make them liberally bounce as your cock raised upwards but then you realized why, those red lines on your dick only came from your Command Seals.

"Uh, Master, did you just-" Da Vinci started but was again interrupted.

“I wonder if that should count as cheating~?” Asked Ushi, “It’s almost like you really don’t want to get bred~” She rubbed her balls along the Master’s shaft, letting the massive cumtanks gurgle and churn as they were used to stroke a cock.

"Fuck my urethra like a pussy, hilt your cock in me, impregnate my balls please~" You had reached your limit, now you just wasted all your Command Seals and the Rider still teased you with those fat gray balls now squeezing your meat in between then.

"I don't want to be a Master anymore, make me your bitch~..."

"I-isn't that a bit much, Master?! Oh this is bad..." Da Vinci could tell Tiamat had finished off a Divine Servant's balls in the background and she could tell Ushi's arousal was reaching peak levels, even worse, Ishtar, Mash, and Quetzalcoatl were stuck too…

“Fufufufu~” Ushi laughed, “You better hurry up and move my balls without cheating this time~ Or else the Chaos Tide is going to impregnate your worthless balls without me even penetrating your sheathe of a cock~” She gripped her burbling cumtanks and started really rubbing them on the Master’s shaft as it got weighed down by those studly nuts, slowly being forced to point downwards and the cockhead threatening to dip into the Tide.

Now that really made you nervous and you struggled as you made the Rider's balls jiggle softly every now and then but it was mostly proving fruitless. "A~" A familiar voice rang out with a hint of impatience and that called your attention to the fact that the Chaos Tide hadn't affected you even a small amount already even though you were firmly stuck in it.

Ushi for her part frowned and rubbed her pair a bit more gently against your cock, letting you jiggle her nuts more easily as you could almost make out a towering horned figure smiling in the mist.

“Fine, you don’t have to lift both, just one…”Ushi muttered, shifting to the side a little so only one nut was resting on the Master’s cock. “Just one last bit of fun before I grace those pathetic things with the Tide.”

That was easy enough, you lifted that massive orb with some difficulty but still your member stuck right up, finally triumphant before the rational side of your brain finally kicked in and told you that you were actually safer before. "I just fucked up, didn't I?"

“The Tide probably would have been gentler.” Ushi admitted, “But if nothing else, once I’m done, you’ll actually have respectably sized balls instead of those stupid raisins.”

"Uh, actually you would have stood a better chance with the Tide and hate to break it to you but your Servants are currently...bogged down too."

"What?!" You shouted as da Vinci broke the bad news and the Rider began to get her cock into position with one hand standing above you.

“Don’t worry, you’ll come to love the sensation.” Ushi assured as she thrusted her hips slightly, bumping the cockheads together, “It’s a shame, though, I was really enjoying rubbing in how superior my balls are, and don’t lie, you enjoyed it when I used your shaft as a toy to please them.”

"N-no..." You stuttered as her tip pushed against yours, the foreskin peeling back as she pumped almost bored, seeming to enjoy watching you squirm as your cock and balls remained jutting out for easier breeding.

“Really?” Ushi sneered, “Because I seem to recall you being utterly entranced by the feeling of my balls resting on your shaft, displaying their dominance with their heft, with the way you struggled to even make them shift or jiggle while I could bounce your pathetic nuts with just my cockhead.”

"Fuck, I want the virile Chaos Tide packed in them splitting my urethral walls on their way to flood my balls and make them into wombs~..." You finally admitted as she kept pushing against your head.

“I bet…” Ushi grinned ferociously as she gripped the Master’s shaft and forced her cocktip to slowly penetrate their urethra, shaping it to accept the throbbing grey cockhead, “You were seconds away from shooting your worthless seed from the balljob I gave you~”

"I-it's so weak compared to yours...why does it feel so good~?!" It was like the Rider's whole body was a potent aphrodosiac designed to make everything she did feel so good, just a couple inches of her tip sent tendrils of intense pleasure throughout your body and brain.

“Now I really wish Mother wasn’t so insistent on using you as a breeding ground.” Ushi lamented, “How I’d have loved to spend my days reminding you again and again of the superiority of my testicles, watching as you try and fail to lift them with your cock while I effortlessly juggle your petite grapes with my own shaft, using my balls to milk out your worthless seed before having the sluts from Chaldea clean them off with their tongues. That sounds so much better, don’t you agree!?” She punctuated her statement with a sharp thrust, forcing her cockhead into the Master’s urethra with an audible POP.

"I-I..." You couldn't even speak, the intense feeling of her tip fully stuffed into your urethra and beginning to stretch out your virgin penile walls getting to your head and keeping you shocked with pleasure. How could it feel that good?!

"No, I want to be a mother~..." The Last Master of Humanity admitted as da Vinci and Chaldea watched which the Rider seemed to be even more turned on by the small blue screen and your slutty face next to it.

“That’s too bad, you’d be better as my ball addicted pet.” Ushi snorted as she started to thrust some more, gradually working her cock deeper, “My balls were what finally broke you, weren’t they?”

"Yes~...fill my balls~..." As more and more inches of Ushiwakamura's gray throbbing meat stuffed inside your urethra that you could visibly see wrapped around that girthy shaft, the Caster watched with an expression of shock and lust. "So big...just how did she make it fit~?"

“Tell me~” Ushi grinned, “How exactly did my balls finally break you~? Describe every last detail to me~” she continued to thrust rhythmically, the Master’s urethra putting up no resistance at all, if anything, it was desperately trying to suck her in.

"They were so heavy that it just felt like my own pair could only be useful knocked up with Yoshitsune kids in my Fujimaru family jewels~...they felt so good running along my shaft and so much more potent than mine~..." You could only moan in pleasure as the Rider kept pumping into your dick with her grin only growing wider as your penile walls clung to her length, the tip stretching them the thinnest. "Make my mage bloodline continuers nothing but a pair of womb sacks for gestating your offspring, taking load after load of Chaos Tide~"

“I bet you felt like if I had laid my cumtanks on your pathetic balls, their very presence would have rendered yours sterile~” Ushi mocked, gripping the Master’s shaft with one hand as she practically used it as an onahole, while her other hand was used to massage one of her gurgling cumtanks, “It certainly would have been the natural order of things~” She continued thrusting, attempting to pace her penetration, even as the Master’s slutty, slutty urethra tried to suck her down on its own.

"I feel like they could only ever get pregnant after that...refusing to let my pathetic sperm come up my cock~..." Your whole body heaved as the Rider fucked you like a common whore, heavy balls leaning against your member as she thrusted again and again with her eyes fully focused on your face as you drowned in lust.

"It is something magical! Her cock is-" Da Vinci couldn't be heard over your moans even as she pieced it together just how Ushiwakamura was so damn irresistible now to your mere mortal body and cock but got completely ignored.

“They could get teased and teased for days on end, but you’d never cum~” Ushi continued to tease, “Just get more and more backed up with breeding material~”

"Sperm cells just ripe for impregnating by your rich Chaos Tide, begging you to make my nuts a womb~..." You managed to barely choke out as pleasure ran through your groin.

“You said you used your cock to fuck plenty of girls back at Chaldea?” Asked Ushi, “Such a shame, all that time you were ignorant of your true purpose~” She leaned in grinning.

“Having this slutty, whorish cock of yours used like an onahole~” Her thrusts turned rough, “Are you even aware of how greedy your cock is~? From the moment I put mine in, it’s been trying to suck me right down~! Practically trying to suck the Chaos Tide right out of me~!”

"Make me your sheath~!" You cried out as she kept trying to bottom out in your urethral tract, not quite hilting herself but ruining your desire to ever fuck any Servant girl again, instead your massive dick was better off just being a cocksleeve.

“I want to hear all about how you want me to use you~” Ushi snarled with Lust as she thrusted with clear intent that she only cared about her own pleasure at this point, “Beg for me to use your slutty cock as the onahole it was meant to be, thank me for using my glorious balls to give your pathetic testicles some actual value, offer yourself to me as a cumdump that only cares about being used as receptacle for the contents of my nuts.” The corrupted Rider grinned in an absolutely predatory manner, feeling the Master’s greedy, whorish urethra gripping and sucking her harder with each word that left her mouth, her cocktip finally bottoming out, almost at the point she’d be hilting herself with each thrust.

"Hilt me~! Breed me~! Make the Last Master of Humanity nothing but a breeding ground~!" You kept saying slutty lines like that as Ushi only kept pumping into your urethra like a wild animal, practically salivating at each new beg and whorish cry escaping your mouth, her grey tits fully erect as they poked out of her bands.

"Well, I should probably go over and get bre-HELP!" Even da Vinci couldn't keep her cool as the statistics for your urethra maintaining perfect structural integrity and your sperm count showed on a control room screen as the disaster continued.

“Be grateful to Mother that I’m breeding your stupid, grape sized balls.” Ushi growled, “If it were up to me you’d just be a sex toy, your slutty cock is the only thing about you that’s even worthwhile otherwise.” The Rider hammered away, seemingly with the intent of ruining the Master’s cock for anything at all other than being her personal onahole, jackhammering her hips at such speeds that the Master’s urethral walls couldn’t keep up as she hilted into the cock again and again

Your penile walls couldn't close as they stretched around Ushiwakamura's meat, each powerful thrust into your urethra punctuated by the vision of her groin fully pressed up against your stuffed urethra with her balls pulsing intermittently as they slapped your shaft. Each thrust into your cock left you trembling with ecstacy as her tip forced your meat to choke every last inch down, a visible bulge forming on the outside of your dick.

“You’re not getting a single drop,” Ushi warned, “Until you profess for all to hear about how slutty your cock is, and how grateful you are that your puny, worthless, pathetic balls are finally going to have purpose.” She used a finger to tauntingly tickle the Master’s balls.

“Be creative and descriptive, I’ll let you know once you’ve done a satisfactory job~”

"My cock is only useful for being used as a sheath by your blade~! It loves clinging to your superior meat as it fucks me like some bitch stuck in a wall~!" You cried out even louder as the Rider thrusted deep inside your cock and made your balls bounce eagerly as they prepared to be bred by her virile Chaos Tide. "Make my puny mage family jewels heavy with a generation of Yoshitsune babies~! Knock my testicles up until every sperm cell I have is penetrated and becomes an egg gestating against my septa walls~!"

“Don’t think you’re done yet~” Ushi kept hammering away without pause, at the rate she was going, it almost seemed like she was fucking with the intent to cause the Master harm rather than to please even herself. She loved the way the penile walls continued to grip her shaft no matter how hard she went, never giving the slightest indication that they’d be made loose.

"Use my slutty cock to hilt your sword~! Stuff my whorish shaft with your potent meat~!" You could hardly take it anymore as the Rider continued to pump her hips without pause, each movement still keeping her within the tight warm embrace of your urethral tract. "Make my worthless balls into womb sacks~! Fill my pathetic balls to the brim with your rich Chaos Tide~!"

“More! More!” Ushi demanded, not letting up the abuse, “Put your everything into it!”

"Use my urethra as a pussy~! Make my balls literal babymakers~! Cum inside my slutty dick~! Stuff my nuts full of kids incubating inside every inch of my septa~!" You shouted even louder as a pleased sound rang out across the foggy Chaos Tide ocean. "A~"

"Turn my cock and balls into a cumdump~!" You cried out in lust.

“Since you’ve asked so nicely~!” Ushi grunted fiercely as she slammed her cock into the Master’s abused shaft to the hilt one last time, her massive nuts letting out a mighty growl as they clenched and pulsed.

"Fuck~..." Was all you could mutter as the Rider's tip swelled up immensely a couple inches from your prostate and you could see her grin covering her face as your tongue hanged out and her red eyes zeroed in on your own.

“Nnngghh~!” Ushi grunted in pleasure as her stuffed balls dumped their payload into the Master’s waiting sack, “I wish Mother had let your arms and legs free after you broke~” she lamented.

“I’d have loved to do this with you squatting with your hands behind your head, a properly whorish pose for someone like you~”

"So much Ushi seed~!" You gasped out.

“Naturally~” Ushi grinned, her balls burping and glorping as they pumped out cum with no end, “Do you hear that~? The sound of a real pair of balls asserting their dominance~?” She reached down and gripped one of the Master’s balls, eager to feel it swell as the Chaos Tide pumped down their prostate and vas deferens

"Yes~..." Your reproductive tubing and prostate were forced open with so much dark-red cum flowing through them, making the vas deferens visibly bulge against your cock as it began to get even longer and girthier.

“I wonder~” Ushi leaned in close with a grin, “How would those balls of yours reacted if you had heard mine making such obscene noises~?” As she spoke, the cumtanks continued to make their lewd racket, glorping, burbling and churning as they jumped and bounced, pumping load after load of sperm down the Master’s tubing, eager to seek out targets to impregnate.

“I doubt your pathetic balls could have even come close to making such perverted, dominant noises~”

"They'd instantly be ready to be knocked up~!" You could feel the pressure building against your epididymes, the Chaos Tide ready to fill your balls next as the rest of your body reacted with constant trembling as Ushi's cum sank deep into you.

"Code red, this is irreversible!" Da Vinci shouted as she could tell the inevitable modifications were about to begin and Chaldea would lose their only Master as a trophy for Tiamat.

“Knocked up just from the sounds my balls made,” Ushi laughed, “Your balls truly were pathetic, at least now they have some value.” She smirked as the Chaos Tide broke through any barrier, blowing past the epididymis with no trouble, before flooding and swelling the Master’s balls.

"Feels so good~!" The Chaos Tide that the Rider came had one unique quality, it had the capability of transforming certain appendages to better fit the needs of Mother which meant that now your dick was approaching eight feet long. Ushiwakamura for her part didn't mind the newly elongated shaft, rather it got even tighter around her with the increased size making it much girthier and she was especially pleased to see your puny balls growing. "They're going to be a pair of wombs for Yoshitsune kids~!"

“Tell me how happy you are that you finally get to have some properly sized balls~” Ushi moaned as she jackhammered away, loving the feeling of the Master’s urethra tightening around her shaft, gripping her and sucking her even more than before, “I can actually sink my hand into them now~” she noted, the Master’s balls starting to overflow in her hand.

"I love feeling them get pregnant~....they're so heavy with Ushi kids~..." Your pair had grown to equally impressive sizes already, now going out several inches over the Chaos Tide and reaching halfway to your previous shaft length, if your legs were free, they’d be reaching a couple inches from your knees. Your vas deferens were like two hoses on the side of your dick as your entire reproductive system was modified so that Mother could use you later but that didn't mean that the corrupted Rider didn't get any fun.

“They’re going to get even heavier~” Ushi growled lustfully as she continued to thrust and cum without end, her corrupted cumtanks churning out equally corrupted sperm that relentless sought out and smashed into the Master’s vulnerable swimmers, impregnating them in an instant, “For the crime of having such pathetic balls before this, your punishment is to have them reduced to slutty womb sacks~” The Rider gripped the Master’s swelling balls, roughly groping and mauling them.

“Just look at them now, my fingers are sinking in without any resistance at all! Not even Mother would have the power to gift such puny, pathetic balls the blessing of being able to impregnate others’ sperm!”

"More~...knock my womb sacks up more~!" You were too far into ecstacy to care as those virile gray swimmers penetrated your fertile sperm cell membranes and got their red nuclei mixing with the ones already in them, your DNA becoming irreversibly corrupted to bear new life for the Chaos Tide. It felt too good having the Rider knead your oversensitive womb sacks so roughly, the swollen veins on it pulsing in protest at the unnatural impregnation and it didn't even interrupt the new sperm eggs in your balls settling against your septa's walls.

"This is awful..." Da Vinci could only gape at the screen showing the mage family jewels' rapidly increasing pregnant sperm cell numbers and yet, more were being produced at a rapid pace by the second.

“Your cock and balls really are such whorish things, aren’t they~?” Ushi asked with a sneer, “You became my seedbed so quickly, I bet those sluts at Chaldea would feel their brains melting if they were to see your balls getting bred~” She taunted the Master on and on as she continued abusing their swelling balls, smacking the orbs and watching in glee as they rippled from the impacts.

"I can feel Ushi kids implanting to my septa for gestating~! It feels so good...I don't want to fuck anymore, I just want to be bred~..." Your knocked up testes continued to pulse in their sack as the corrupted Rider kept playing with her new conquest, the feeling of them being turned into a fertile breeding ground for Lahmu had completely overwhelmed your brain and so many young already beginning to grow nice and healthy deep inside the nooks and crannies of your septa only added to the lustful haze your gaze had.

The words just fueled Ushi to keep up the abuse.

“Not like you were good for anything else~!” She said as she continued slapping the swelling testicles, “If my sperm is taking this easily, clearly your stupid, slutty balls weren’t ever meant for anything other than being bred~” Her constant slapping and groping was covering the Master’s balls in handprints, and the constant growth meant she always found space for more.

You could feel Ushiwakamura's groping send stings of pleasure throughout your body and each slap made the impregnated orbs below your cock jiggle liberally as her Chaos Tide fully settled in them. It seemed the corrupted Rider was reaching her limit as her flow got thinner to let your stretched thin penile walls attempt to close up but only really kept her gray meat covered in your tight warm cockpussy.

“You actually managed to drain me~” Ushi panted as her balls quieted down, their lewd cacophony no longer echoing around the space, “Guess that’s a testament to just how slutty your cock is, how eager your whorish nuts were to be impregnated~” She pulled her corrupted cock from the Master’s shaft, her balls visibly smaller than before, but quickly swelling back up to their previous size, her cock head still drooling like a faucet, and emphasized her point by giving the Master’s balls one last sharp smack.

"Mngh..." You slowly got a bit of rationality back as the Rider left your shaft and took in not only how large your cock had gotten from the Chaos Tide and how much your balls tingled pleasantly but it still felt wrong. Ushi being pleased that she had turned them into womb sacks rapidly producing sperm for more impregnating and even able to grow further, fully fulfilling her role as the plow and getting to sow her seed in those babymakers herself.

"This is bad...it's like Tiamat's Potnia Theron skill has been transferred to your balls! Is that-" Da Vinci shouted as a new form showed up on the scanner, a massive one.

“Mother’s here~” Ushi grinned, “Do try to be a good broodmare for her, will you~? After all, it’s through her generosity that your balls finally have some worth~” She couldn’t help herself and sharply smacked the Master’s balls yet again.

The horns were the first thing to cut through the mist over the Chaos Tide Sea and soon revealed the full form of Tiamat, the Goddess of Beginning and her impressive assets were on full display. While she had another massive rack on her chest topped with pink tits already fully erect, it was her massive cock that caught your attention with it being at least nine feet long and extremely girthy with muscles already pumping blood to that potent shaft. The Beast's meat was already leaking precum out her tip as she looked down at your face with a slight hint of arousal on her features while her balls that reached her shins began to audibly churn as she let out a pleased note. "A~"

"Oh, now you are officially fucked Master..." Da Vinci could only stare at that massive cock Tiamat had standing fully erect in your face.

“I, uh…”

“What are you waiting for!?” Ushi snapped, “Offer your gratitude that Mother is using you to birth the new humanity!” She gave another hard smack to your balls.

“Hhhiiiiieee~!” The sharp sting had you gritting your teeth as your overstuffed cumtanks rippled and sloshed.

"A..." Tiamat sounded almost worried with that noise as she moved one of her large hands downwards to gently scoop up the new breeding ground her Rider had prepared, the Last Master of Humanity had taken to her blessing perfectly and what's more she could detect new life already forming in your balls. A pleased smile grew on the Beast's lips as she then caressed your massive member with a loving rub along the entire length and width while gently massaging those knocked-up orbs you had on your legs. But Tiamat wasn't just being kind, no, she admired you for your determination but she wanted you to bear the new generation of humanity as a fitting seedbed to end Uruk, Chaldea's Master would be her personal broodmare and your potent mage line continuers would bear many Lahmu for her...

"A~..." The Beast sang as her erect cock noticeably throbbed at the thought and confident that the measuring she did during her massage was accurate and would enable her to fully grace your shaft with her divine meat and claim your cockpussy for her use.

“Just… just ruin me~” You gasp out, “Just gape my worthless, slutty cockpussy as you breed my whorish balls~”

"A~!" Tiamat exclaimed with eagerness in her purple eyes as she began to line her tip up to your swollen cockhead, the massive pink tip pressing against it with one powerful thrust of her hips that she kept pushing into. "Master, have you completely lost it?!" Da Vinci shouted out as the Beast smiled gently down at you as she kept pushing, slowly making your urethra stretch wider to accommodate her tip and making her increase her force from the pleasure, it was better than Gorgon!

"A~" She turned to Ushi and gave her thanks for preparing you for her Mother's use.

“Anything for you, Mother,” Ushi called up, “It’s a shame, though, I had so much fun breaking them, I don’t think I’ll be able to find anyone else who could offer me that much fun…”

While she said that, you could only moan as Tiamat’s frankly monstrous shaft spread your penile walls even more than Ushi had, unable to articulate your thoughts, you wished you could retort to Da Vinci that she had been the one who wanted to slobber on Ushi’s cumtanks.

"A~" Tiamat had only barely gotten her tip in your urethra and quite frankly it was gaping from that divine meat entering it but her huge breasts bounced as she kept going for hilting her lance of a cock in you. The Beast even licked her lips as she slowly bucked her hips into your urethral tract, breaking in your tight warm insides to Mother's loving breeding as she began to massage your womb sacks with the utmost care and tenderness, having no need to steady her member. "A~!"

“Harder…!” You gasp out, you don’t know if you’re referring to her penetration of your urethra, or the handling of your balls, though there’s no denying the gentle massage feels nice, your balls churning and burbling in response.

“They like to be treated roughly, Mother!” Ushi called out advice, “Treat them like the cheap whore they are!”

"A~" Tiamat gently kneads the impregnated sack with a bit more force and truly appreciates how the testes within are simultaneously so firm and large while their covering is so soft and squishy. Of course, the Beast is still more cautious than the Rider as she moves to a third of the way down your shaft, the penile walls desperately clinging to her and clenching up to hug their Mother which only makes her want to ram her pink tip down more but she increases her force, only wanting to make you enjoy being bred as much as she does mating you. "A~"

"How can you even take that thing?!" Da Vinci yells even as she's drooling.

“I’m just an onahole~” You moan as Tiamat’s cock stretches your walls, “I’m just a slutty, slutty onahole to be used and bred~” Your clouded mind can’t decide if you prefer Tiamat’s massaging of your firm yet squishy nutsack, or Ushi’s abuse and mockery.

"A~..." Tiamat's loving smile only grows wider as she gets deeper in your penile walls, her potent cumtanks already refilled from her slight delay with that Avenger slapping liberally against your massive member while her rack jiggles in your face. The Beast's purple eyes look into your own with love as she pumps her fat cock slightly below halfway in your urethral tract and you can still see a good amount of that divine schlong outside of your visibly stuffed urethra while she runs her fingers along the many veins on your pregnant balls in addition to her massage.

“I’m sorry for not offering my whorish cock and balls to you sooner,” you said, “But before Ushi got to me my balls were too puny and pathetic to be of any use, I had constantly been emptying them when I should have been saving my sperm to be impregnated…” In your haze you slowly reach out to the massive mommy milkers as your cock needily tries to suck down the Primordial Mother’s shaft.

"A~..." Tiamat lowers her body down to let you grab her plump tits as her tip finally pushes through the last few inches of your penile walls and right to your prostate before pressing up against for a couple moments until a loud POP! The Beast wriggles the last couple inches of her meat outside your urethra next to your eager tip as she grinds her cockhead against your vas deferens which stay completely open for easier breeding after Ushi was done with you.

"A~!" Tiamat says almost triumphantly as she rubs your knocked-up mage family jewels with a hard but tender grip as she makes them bounce around before placing her own ample sack on them with a moan and wide, bright eyes looking at you for a pleased response.

“Ooooooooohhhnnn~” You moan as you lean forward, doing your best to get a fat nipple into your mouth, feeling your prostate get slammed really got your balls churning, producing cum not to shoot out, but to be impregnated. Tiamat’s massaging making it swirl around. Your scrambled mind has somehow reached the conclusion that the solution to your earlier dilemma is to obviously have Ushi here, smacking and beating on your nuts while Tiamat massages them.

"A~" Tiamat makes her full cumtanks rub all over your womb sacks, her Lahmu breeding ground, as she pulls back with her wide hips and begins thrusting with powerful slams that still are her holding back despite them making your urethral tract flare up with pleasure. The Beast's divine meat continues to fuck your slutty cockpussy and visibly engorges your girthy shaft as your frantic suckling of her nipple turns her on even more, her own nuts sloshing as they are aroused and she forces your fertile womb sacks to press against her virile seed containers as her tongue hangs out and her purple eyes look down at you as her voluptous body leans against your torso. "A~!"

“For Mother to make such a face, your cockpussy must be truly slutty and fit for breeding!” Ushi marveled, “Oh, how I wish I could keep punishing your balls for being so slutty and pathetic, but before long, I won’t be able to do that without putting the young within them at risk…”

The thought of the corrupted Rider abusing your balls some more has your nuts pumping out fresh seed for impregnation as you moan into Tiamat’s nipple, your mouth desperately sucking on the fat nub hoping for milk just as your cock desperately sucks on Tiamat’s own divine shaft.

"A~" Tiamat kept pumping her wide hips downwards, your urethral tract greedily taking over eight feet of her girthy meat that stretches out your penile walls immensely with her relentless breeding pace. The Primordial Mother was clearly oblivious to the fact that her thrusts were becoming more akin to a Beast's than loving but she fondled your fertilized right ball with her left hand while stroking your shaft with the other and shifting over to let the corrupted Rider back at you as she kept her huge breast glued to your face. "A~"

"I need to go over there now! Or will I just be screwed too..." Da Vinci monologued as she tried to decide what the best course of action would be with the prime view of the Last Master of Humanity's stuffed urethra choking down Tiamat's dick on full display in the Command Room.

“Letting me get in a few hits in before the young are too big? You’re too kind, Mother~” Ushi grinned, bringing her hand back.

You continued to suckle on Tiamat’s nipple, hoping for milk, whining slightly when you no longer felt her hand on one of your balls, only to stiffen and squeal as you felt the familiar sting of a certain Rider’s hand cracking against your massive breeder balls.

“I don’t think I’ll ever get over how much of a whore you turned out to be~” Ushi mused as she smacked your balls a couple more times, “Who enjoys having their balls treated like this? Not that you really deserved to have them called balls in the first place, not when they used to be so pathetic.” She dug her hands into the orb, groping and mauling it, sloshing it around like an immense stress ball.

"A~, A~, Aaaaa~!" The rough treatment made your penile walls clench up even tighter, the intense warm loving grip making Tiamat go into a frenzy as she thrusted with no desire but to impregnate your breeding fields personally. The Beast was a bit sad that her balls began to cling to her groin and precum leaked more liberally from her tip as it battered down your walls with her monstrous futahood hilting inside your dick and prostate again and again.

"Aaaaa~!" The Primordial Mother could only cry out and moan again and again as she kept massaging your right nut and tracing the swollen pulsing veins on your sack with her fingers, oblivious to the fact that the sight of your body had made her balls snap her panty right off and now she made the Chaos Tide shake with each movement.

The conflicting pleasant and painful yet pleasant sensations had utterly melted your mind. You couldn’t even form thoughts to fail to articulate. All you could do was moan as your penile walls clenched like an electric toy, desperately and sluttily sucking on Tiamat’s meat with even more fervor.

“Enjoy this treatment while you can!” Ushi said as she roughly gripped the swelling but with one hand while repeatedly slapping it with the other, “Because before long you’ll have too many growing young in them for me to do it safely! I’d tell you to thank me for being so generous as to treat your worthless, slutty balls to this one last time, but I wouldn’t be surprised if your slutty brain has completely overloaded!”

Her insults fell on deaf ears as you continued to desperately suck on Tiamat’s nipple in hope of milk. Your entire world has faded to nothing but the fat nipple in your mouth, the massive shaft in your slutty onahole of a cock, and the contrasting treatment of your balls, gentle massaging on one, harsh slaps and mauling on the other.

"Aaaaa~!" Tiamat was getting extremely close to bursting in your member, every inch of your penile walls drove her further into ecstacy as her monstrous cock was gripped by them with increasing pressure as she moaned and let her tongue hang out. The only thing the Primordial Mother could do was keep thrusting into your tight warm urethra's embrace, press her massive breast up against your face, and massage your womb sack with as much love and care as she could offer while running a hand along your dick to jerk you and her off. "Aaaa~!"

The Beast's pumps deposited a few drops of her extremely virile cum, the desire to make those fertile breeding grounds once known as the Last Master of Humanity's balls into Lahmu producers growing nearly unbearable as her cumtanks audibly churned and pulsed periodically against your shaft.

Your thoroughly impregnated womb sacks jiggling as her movements rocked your body and the Chaos Tide that she stood on the waters as they laid on your knees and the muddy liquid, still maintaining their natural color but that only meant you would be an old human mage birthing so many of your new and improved successors.

The instant the Primordial Mother’s cum started to enter your balls, your eyes rolled up into your head, nothing mattered anymore. You could barely even process or acknowledge anything going on around you. It would be days or weeks before your mind might recover, if it ever could. All you knew was pleasure and the desire to be bred. You could hear faint noises, but they couldn’t be important, being bred and used were all that mattered.

“So Mother’s finally graced these pathetic things with her cum?” Ushi noted as she continued her testicle abuse, she alternated which hand was gripping and mauling the nut and which was smacking it, “You can’t even appreciate it, I can just tell that you’re slutty mind has long crumbled!” The Rider decided to take her rough treatment up a notch and started using her mouth, biting your immense nuts. Not hard enough to cause actual harm, but still enough to leave visible bite marks.

The only signs that you could even still feel what she was doing was the clenching of your urethra, and the weak kicking of your legs.

"A~....A~...Aaaaaaa~!" Tiamat hilted herself with one last cry that filled the air in the Chaos Tide ocean as she finally climaxed, her entire monstrous divine shaft finally twitching relentlessly as her cocktip trembled next to your vas deferens before depositing her seed directly in them. The Primordial Mother's sperm cells were surprisingly the same size as your own but that simply let a flood of them go through your reproductive tubing and your bloated epididymes to get to work on breeding the fertile seedbeds they entered. Your own swimmers were ripe and vulnerable for knocking up with Lahmu, her sperm pushing through the cell membranes to get to the rich nuclei in the center of the Last Master of Humanity's future offspring, DNA that could have made some powerful human mages now used to mate with a Beast's seed and forced to conceive monstrous young as her divine nuclei forced yours to combine over and over in seemingly endless breeding pairs of sperm cells. "Aaaaa~!"

Tiamat's eyes rolled up as her huge cumtanks began unloading everything they had into your womb sacks, your cockpussy still suckling your Mother's meat while you sucked on her tit mindlessly, her massaging of your cock and ball ending as she fully gave into pleasure for some very passionate moments.

“Mmmf~?” Ushi’s eyes widened, having been in the middle of giving your balls another bite when she felt them start to swell at a rate that easily outpaced what she herself made them go through.

Your mind seemed to black out completely as your balls bloated at an absolutely obscene rate, quickly reaching the point that even the one nut in Tiamat’s hand quickly overflowed it, even threatening to swallow up the hand completely. Your womb sacks grew so big that even with all the milking in the world, they’d never go back to anywhere close to their original size. You couldn’t even be considered a person anymore, just a breeder.

“Such massive balls…” Ushi stared as she was forced to back away from them, “Such massive, slutty breeder balls…”

"Aaaa~..." Tiamat slowly came off her high while depositing the last of her baby batter into your breeding grounds, the flow remaining thick as she pumped it all out into your reproductive tubing and filling it with as much warmth and pleasure as she could provide. The Primordial Mother bucked her hips a few times to make sure her seed was all packed into your mage family jewels, the Lahmu sperm eggs beginning to settle into every trenchlike wall of your balls and the cavernous bottom to gestate in the Last Master of Humanity's babymakers. The Beast gently rubbed the massive ball in her hand with a surprisingly lewd smile and admired how well your testicles had formed into such wonderful wombs, eager to bear her endless offspring as fresh sperm cells were producing at an unbelievable rate for Tiamat to impregnate later.

"We lost Master..." The last thing shown from the Command Room Screen before it was shut off was the Primordial Mother's monstrous divine meat buried in your shaft, your stretched urethra seemingly slurping on it as those virile cumtanks slowly refilled before da Vinci called the Babylonia disaster a complete failure.

“You must be proud of yourself~” Ushi smirked, “You’re packing quite a lot of young in there~” She gave your balls one last mighty slap.

“Guess it’s only natural that balls as slutty as yours get knocked up~”

“Sho much…” You slur, drool dripping from your mouth, “Sho much…” You don’t even react to the smack.

“You really are broken,” Ushi sighed in disappointment, “To discover and lose my favorite toy in such a brief moment…” she turned to Tiamat.

“What would you have me do next, Mother?”

"A~" Tiamat says to you one last time with a sweet loving tone as she slowly pulls her monstrous divine cock out of your stretched urethra and kneads your massive womb sacks with both her hands as her wide hips move upwards. Her purple eyes look at your face with love as your penile walls remain split open from her meat, your shaft now only able to be called tight if she's the one breeding you and her cocktip throbs one last time, letting a short burst of the Beast's seed out. The Primordial Mother is happy to see your impregnated balls expand slightly more over the Chaos Tide as they would more than cover up your legs if they were freed and smiles proudly as her cockhead pulls free of your urethra with a POP!

"A~..." Tiamat giggles slightly at the sight of your gaping cockpussy still clenching like it wants your Mother's meat to use it as an onahole so she can breed your womb sacks even more, the knocked-up orbs so heavy with Lahmu, your Mother's offspring in every corner of your septa with Ushi contributing her seed as well, bounce more liberally than her breasts from the force of her pulling out and she pats them lovingly as she turns to the Rider. "A~"

“Sho… sho… full…” You slur, the whole world spinning, a veritable ocean of cum in your nuts, every slosh sending waves of pleasure through your body, your sack felt stretched taut in the best possible way from how stuffed it was, “My shlutty breeder ballsh… are sho full~” Without another word, everything goes black as you fall into pleasure induced unconsciousness.

Ushi could only stare as Tiamat offered her her divine cock.

“You mean it, Mother?” She asked, “You’re going to have me bred as well?” She looked up at the Primordial Mother, eyes full of gratitude.

“I would love nothing more~!” The corrupted Rider walked over to the Beast, and lined up her cockhead with Tiamat’s urethra, eager to have her own balls turned into womb sacks. Womb sacks that would surely outshine the inferior balls of Humanity’s Last Cumdump.

As this was happening, your body continued to twitch. The feeling of air flowing into your gaped cockpussy, the lingering sensations of it being stretched out by Ushi’s, and later Tiamat’s, cock still fresh in your body’s memory. A sensation it would never forget or get tired of, a thorough addiction fitting for a slutty cockpussy onahole like yourself.
