“Doesn’t this feel good, sweetie? Don’t you like how every inch of your body can’t wait to take my cock and worship it?”
Shiga was lost in pleasure, as he usually was when his mistress decided to play with him. While normally she used his asshole or his fat tits to shove herself into, this time she decided to take a different approach.
Shiga was sitting in her office chair, his modified dick and balls out, and currently the Librarian was balls deep in his urethra. Shiga could barely think, could barely see through the haze of pleasure, but he couldn’t help but be mesmerized by how thick he was with her massive cock stretching him out from the inside. Every movement had her glans and veins scraping the inside of his cock raw, stimulating him in ways he could only inferiorly imitate with a sounding rod.
Of course only she could do something like this to him. She was the one who had his body and mind molded to her liking, after all.
“Mistress, I- f-fuck…” He was doing everything he could to not fall over in the chair or pass out from this. “My cock…”
“Mhm, your cock is a special little pussy for me too.” She held onto his swollen shaft as she started moving a bit faster. “Your tightest little pussy just for me~” Shiga threw his head back, resting it on the back of the chair as his moan came out more as a pathetic gargle. By the time she was going to cum, a sweet smile crossed her face as she knew exactly what was going to happen.
“You ready for me, sweetie?” She asked, feeling her balls tighten up. She’s saved her load specially for him, specially for this moment. Shiga nodded, trying to make an affirmative noise, but it just came out as another whine.
“I’m gonna get your balls pregnant~”
With that, she plunged in all the way to the base of her cock, making sure every inch of his urethra was spread wide open, before she came deep inside him. Shiga wanted to cum too, but couldn’t because of how thoroughly he was blocked. All he could feel was cum rushing into him instead of out of him. Back, back towards the source.
He could feel his already large balls starting to swell with his mistress’ huge futanari load. He panted and groaned in ecstacy at the feeling, his sack growing taut as he continued being filled up. By the time she was finally done pumping him full of her potent sperm, she pulled out of him, leaving a sticky, wet gape in its midst, but no cum dribbled out of him, either his or hers.
“Why…” He gasped out, gingerly touching his balls, which were the size of basketballs and resting on the seat of the chair. “I wanna cum…” he whined. “Why can’t I cum?” The Librarian bent down, putting her dainty, gloved hand against his sack, closing her eyes as if she was listening intently through her hand. She then opened her eyes with a smile, gently petting him.
“Because all your sperm’s being gangbanged by mine~” She explained, starting to lightly pat him. “And I got your cute balls pregnant!” Now that Shiga was not actively getting his cock fucked, he could hear her properly. Despite the overwhelming feeling in his nuts, he still found it within him to stare at her like she was insane.
“You what?” He flatly asked. “How?” She turned around, blushing intensely as she pressed the tips of her fingers together.
“Power of love~”
“You’re a Custodian, right? And your body was modified like one.” The Librarian had brought over the book that she wrote, the same one that Shiga and Ton delved into that brainwashed and modified them into being her sex slaves in the first place. She cracked it open, and Shiga found the inside was entirely handwritten in pink glitter gel pen. Given the sheer length of that brick, he couldn’t help but be impressed.
“Yeah, Custodian 1169…” He rarely used his android name anymore, only when his mistress was physically overriding his body, but it was still nice to be acknowledged. The Librarian found the page she was looking for, reading aloud.
“‘Custodians had a whole host of privileges and modifications that made them far superior to humans, or either other androids.’ Skipping that, skipping that… talking about your fuckable nipples…” She flipped a few pages, which Shiga assumed were talking about his nipples, before she continued. “There we go! ‘Custodians also had large, incredibly fertile testicles. While 1169 was a breeder first so her sperm was already fertile, what she didn’t realize is that her actual testicles also acted as wombs! Should a superior futanari dominate her and pump her tight urethra full of cum, why- her balls would be impregnated instantly, ready to birth out another android through her cock in no time.’” She finished reading, closing the book and pointing at herself.
“I’m a superior futanari, and I pumped your tight urethra full of cum.” Shiga blinked in shock, still trying to process all of this.
“I can’t believe you wrote that in.” He mumbled. “Like… how many situations like this did you write into that book of yours?”
“A lot.” She simply answered with a shrug. “I had one shot at this, so I wanted to modify your body to do as many potential future things as I could think of.” Shiga nodded slowly, looking back down at his balls, which looked so heavy…
“I don’t… I don’t know if I’m ready for something like this. This is really weird.” The Librarian’s smile didn’t break. There were some drawbacks to letting Shiga have a personality, but nothing she couldn’t easily fix.
“Custodian 1169, this is your Mistress speaking.” Beneath the personality he was allowed to have, Shiga was still the brainwashed android slut that she made him out to be. His eyes appeared a bit lighter green as his face fell into a neutral expression.
“Hello, Mistress.” He robotically responded.
“Custodian 1169, every inch of your body is mine.” Shiga gave a firm nod. “Every hole of yours is mine to do whatever I want with.” That they were. “You’re so lucky to have your balls impregnated by my huge load. You love it, and it turns you on. Understood?” Her words soaked into his brain as he saluted her, still sitting in her chair.
“Understood, Mistress. Thank you for impregnating my modified testicles. It makes me very horny.” She nodded, taking a moment to enjoy this look on his face before she decided to free him.
“Resume civilian mode.” Shiga’s eyes returned to normal. All that uncertainty from before was now gone as he licked his lips, reaching down to try and hold his balls in his hands, but they were far too big for him.
“I’m gonna have babies in these things…” He chuckled, his face flushed as he got visibly aroused. “So what’s the gestation period? Is it nine months like a regular pregnancy?” She tilted her head to the side, her smile ever-present.
“No, it’s four hours.” Once again, Shiga was caught completely off guard, staring at her in shock.
“... did you just say four hours?” With that, she nodded.
“I’m impatient sometimes.” She explained, bashfully putting a hand on her cheek. “Like Ton-chan can give birth in five months instead of nine. I could make up whatever rules I wanted for getting your dick pregnant, so I wanted to make it short and sweet.” Shiga had started to sweat, feeling a whole slew of emotions from the lust that she programmed him with, to fear.
“F-Four hours…” He breathed out. “And how much are my balls gonna swell?”
“A lot.” There was no use sugarcoating it. “Lots of cum production that you can’t let out in order to support the growing babies. I’d get some food while your balls are just huge.”
It was so uncomfortable walking around. There was no way Shiga would be able to hide his pregnancy in his pants, so he had to go to the Dining Hall with the hypnosis field collar on and no pants. Instead, he wore a sort of harness meant to support the heavy weight of his balls. Even so, he had to carefully walk down the hall, each move he made stimulating him. He couldn’t get hard, though, and he couldn’t cum. He just felt his nethers throb relentlessly as he finally went to eat.
God, he was so fucking hungry. He didn’t realize it until he took the first bite, but he was starving. Within minutes, he wolfed down the entire meal, but that wasn’t nearly enough. Getting up was a pain, his balls straining against the harness, but he managed to make it over to get seconds. He didn’t just get one helping for seconds, though, but closer to five. Sitting back down, he shoved an entire bowl of rice down his gullet before he could even process how hungry he was.
“Wow… didn’t expect you to have an appetite like mine, Naoya-san.” Takiji had shown up for lunch, and couldn’t help but be amazed by how much food he was eating. “Normally I’m the one with so many helpings.”
“Oh hey, Takiji.” Shiga gave him a nod, talking with his mouth full. “Yeah I’m… just starving today.”
“I’ll say, you’re eating like you’re pregnant or something.” Takiji had no idea how right he was with his little joke. “May I eat with you?” As Shiga nodded, he went off to procure his own meal. Shiga almost choked on his food, but narrowly managed to avoid it. All these sensations were so new for him, but the one he could feel most prominently was that he was still swelling.
His balls definitely, as he had to go through his entire pregnancy in four hours, but other parts of him too. His cock ached, his urethra still open from being stretched so thoroughly, and he could feel it swelling and throbbing as well.
He’d wasted a little bit of time since he was impregnated, so he was actually on hour two of his four hour gestation period. He could feel the baby inside him… babies? He wasn’t too sure. He could feel the babies inside his balls grow as they developed, stretching him out from the inside.
It wasn’t just his genitals too, but he felt a tightness against his chest. He usually bound his huge breasts, but that was starting to get uncomfortable. Were his tits growing as well? That wasn’t good, they could break his binder at any moment!
“Sorry about the wait.” Takiji came back, sitting down next to Shiga, who was panting and gasping, his face flushed from the swelling feeling. “Hm? Naoya-san, are you ok?”
“Y-Yeah, I’m fine.” He quickly nodded, trying to take another bite of food, but his hands were shaking. He needed to cum, but he couldn’t until he gave birth. If only Takiji could properly see him, sitting here with his huge, pregnant balls, fat ass, and-
He heard a small rip of fabric coming from his chest, making him squeak and his eyes snap open. His binder and shirt were going to tear open. Right here in the Dining Hall. Right next to Takiji, right out in public, and none of them would be able to tell. They couldn’t tell that his body was so erotically swollen, that he was just a pregnant bitch in heat.
Then, it finally happened. His binder broke. All of a sudden, his shirt was full with the biggest, bounciest pair of tits, the sudden force of them coming out making the buttons on his shirt pop off. Now they were completely exposed! They were so much bigger too, now comfortably splayed out on the table before him. His nipples were just as big as always, though Shiga now saw creamy yellowish-white milk bubble forth from them.
He’d started to lactate? Already?
“I… I need to go.” He mumbled, in a daze from the overwhelming pleasure.
“Huh?” Takiji tilted his head to the side, internally wondering if he did something wrong, or maybe Shiga wasn’t feeling well. “Alright… let’s catch up sometime, though.” Shiga nodded with an uneven bob of his head before he tried to stand up.
He was so heavy… Shiga tried to carry his huge, leaking boobs in his hands, but they constantly threatened to spill out over him. Not to mention he was getting milk everywhere, it gushing out of his fuckable nipple holes. His balls were getting too large for the harness too, and he could-
He jolted as he felt a kick. A kick coming from inside his balls. This was real, and he needed to get back to safety before he grew any more. Or worse, tripped and fell, his collar breaking. What if he fell at the entrance of the dining hall and suddenly everyone would be able to see him? No longer as Shiga Naoya but as some huge pregnant slut with boobs reaching his stomach and swollen balls reaching his knees. They’d be able to see his plugged up ass too, how big it is. They’d pull his plug out while he lay helpless on the floor and rape his hungry asspussy.
He wasn’t going to make it back to his room. Luckily, there was a stop along the way.
“Keep going, Igo…” If anyone knew about getting impregnated by Nausicaa, it was Satomi Ton. He’d given birth to four children of hers already, and had just gotten stuffed with his fifth. It was very convenient that his room was so close to the Dining Hall, as Shiga could safely hide with his fellow slave. They were on the floor of Ton’s room, the man currently squishing Shiga’s balls around his own dick as he thrusted between them.
“I didn’t think they’d get this big!” He exclaimed, making sure to grope and massage the mounds. “They’re just swallowing me up!”
“Y-Yeah…” Shiga leaned back on his hands, enjoying the feeling of giving a balljob. “I had to bail from the Dining Hall, but Takiji was sitting next to me. I wish he could see me…” He reached up, slipping two fingers into his urethra to casually finger himself. “I wanna enslave him so bad. I wanna seduce him, get him utterly obsessed with me. I want him to become so overcome with lust that he rapes me.”
“Maybe you can!” With a shudder, Ton shot his load between Shiga’s balls, keeping his sticky cum between them as he pulled out. “After all…” he panted, “you’re carrying her children. I’m sure you can ask Shisho-san if you can seduce and enslave Kobayashi-kun.”
“God I fucking hope so.” He muttered, casting his eyes off to the side. “How long until I give birth?” Ton flicked his head over to the right to check the wall clock.
“Bit more than an hour.” Shiga nodded, feeling the babies kick again. With that, he lay on his back, his leaking tits spilling out to either side of him.
“I’m just gonna camp out here until then. Can you get her when it’s time?”
“Sure thing, Shiga.” Ton lay on his back as well, though with a heave, he lifted Shiga’s cum covered balls to the best of his ability. Pushing himself so he was under them, he let them smother his face. They covered him completely, suffocating him with their pregnant, musky scent as Ton started frantically jerking off.
“I heard it’s time!” An hour later, when Shiga’s dick had suddenly hardened and started spewing out amniotic fluid like a fire hydrant, Ton ran as fast as his legs could carry him to get the Librarian. The two of them returned, seeing Shiga lying on his back, panting and moaning in intense pleasure as his swollen balls pulsed and throbbed. Nausicaa the Librarian knelt down by Shiga, inspecting the state of his cock. It had grown to around 20 cm in diameter and close to 50 cm in length. His urethra was still gaping, but not nearly enough to safely deliver.
“Alright, we can do this.” She put on a glove, this one going all the way up to her shoulder, before she plunged her fist down Shiga’s urethra to open it up further. This caused him to squeal and moan, panting quickly to catch his breath between them. He was sweating profusely, as he was overcome by such a strong mix of pain and pleasure that he couldn’t tell what was what anymore.
“It’ll be ok, Shiga.” Ton went to hold his hand, only for Shiga to tightly grip it. He pat Shiga’s hand with his free one, giving him a tender, understanding smile. “Giving birth is really fun. You’re gonna cum so hard.” Ton was looking forward to this. He wanted to see Shiga cum from giving birth. He had poked fun at Ton for developing a birthing fetish, now it was time for the tables to turn.
“Alright, you’re dilated.” She brought her fist back out, her glove absolutely soaked. “Are you ready, Nao-chan?” Shiga couldn’t respond. His vision was getting hazy as he took the deepest breaths he could. There was so much pressure in his balls not only from the pregnancy, but the fact that he couldn’t cum for the past four hours. He couldn’t wait to get it all out. His huge balls started to clench, and he could feel it: the prelude to the biggest orgasm of his life. He gripped Ton’s hand tighter, starting to play with his chest with his other hand.
“Come on… gotta cum…” He mumbled in a bit of a daze, the Librarian quickly nodding.
“Cum for your Mistress.” She urged him, keeping one hand at the ready but reaching underneath to grab the base of his anal plug, pulling it out and pushing it back in, fucking him with it.
“O-Oh…. Fuck my-” His heart stopped in his chest as he felt it. Something large coming up his urethra, like a thick wad of cum. “It’s coming…? It’s coming!” He cried out. That had to be the baby! He felt himself grow a bit delirious as he pushed with all his might. He was so close to cumming as he felt the bulge travel further along.
“Almost there, you can do this.” He was cheered on, but it did little to ease Shiga’s fatigue or burning arousal. The Librarian watched his slit earnestly, vigilantly paying attention until she saw what she was looking for. There it was! His hole widened only further, and a soft, smooth, flesh coloured surface started poking out. Nausicaa gasped, shoving the plug all the way back in so she had both hands free. Shiga was in so much pain as the baby’s head was finally pushed out of the head of his cock, but the overwhelming arousal masked it.
“The head’s out!” She announced, supporting the tiny thing with her hands as more and more of the child got pushed out of his urethra.
“You hear that, Shiga? You’re almost done!” Ton tried to keep his friend and fellow slave optimistic and more importantly sane, but Shiga was a mess by this point. Openly sobbing and groaning, Shiga tried to squirm around, but was weighed down by his own body.
“My cock’s gonna rip!” He cried out. “It’s stretching me so wide!” Ton gently shushed him, petting his hair as the rest of the baby finally popped out. The Librarian gasped, holding the tiny newborn in her arms.
“It’s a-” She noticed the child’s penis, which was on the large side for a baby literally seconds old, but that told her nothing. “I have no idea!” She snipped the umbilical cord, but this was the calm before the storm. Shiga’s urethra was still wide open… and something was coming.
“A-Ah…” Shiga gasped out, his eyes wide but unseeing. His whole body was shaking with anticipation, his balls still clenched tight. Ton and Nausicaa shared a knowing look before the Librarian stood up, still holding the baby. She took a few steps back to try and leave the blast zone… before she raised her foot and stomped it down on his balls as hard as her tiny body could manage.
The effect was instantaneous. Shiga’s back arched so suddenly it was like his spine would break as a near inhuman scream left his lips. He couldn’t even form coherent words as long, thick ropes of cum spurted forth. It was like a geyser explosion that he couldn’t stop once it had already gone off. He spasmed and shook, his toes curling as it felt like every inch of him was being electrocuted. It just kept going, the fat ropes of cum landing wherever they pleased be it covering Shiga’s body or getting all over the floor. Both his cum and hers, all that was used to grow and nurture the baby.
Which had started to cry.
Shiga’s orgasm finally settled down, the last bits of cum dribbling out of his abused slit, sliding down the sides of his cock. His balls were much less swollen now, still bigger than they were before but not nearly as large as when they were pregnant, and his dick size had shrunken a bit too now that its job was done.
“That sure was something~” The Librarian whistled, cradling the crying newborn in her arms. “So what do you think of testicle pregnancy, Nao-chan?” Shiga had passed out at some point during his orgasm, laying there with a somewhat stupid look on his face. She blinked, before she laughed a little with a shake of her head. “Oh well…” She then looked over to Ton, who was looking around at the mess Shiga had made in his room. Amniotic fluid, cum, and blood everywhere.
“Ton-chan, could you clean up in here?” She asked sweetly. “I have to take care of the baby.” Ton gave her an obedient nod, as he couldn’t disobey her, but once she left, he mentally cursed Shiga for having to use his bedroom to give birth.
“It was insane.” Ton mused. Some time had passed and Shiga had finally woken up, so the two of them were taking a stroll in the courtyard. “You were cumming like… so much.” He looked up to Shiga with wide, curious eyes. “Do you think next time, I could ride your dick so the baby that comes out of your dick goes straight into my womb?” Shiga blinked at him, a little taken aback by the brazen question.
“No way your cervix can stretch that much.”
“You don’t know me, my cervix is very fuckable.” He insisted, a little bit offended. “Anyways I just think it’d be hot.”
“Yeah I bet you would think that, you birthing fetish freak.” Shiga reached over, teasing him as he lightly poked his cheek. “Addicted to pumping out babies for mommy, are you?” Ton swatted his hand away.
“You’re one to talk!” He pointed accusingly at Shiga. “I literally saw you cum your brains out and pass out after you shot a baby out of your dick! No way you’re not a slutty, addicted breeding bitch after that!” Shiga rolled his eyes, shoving his hands into his pockets.
“You’re just projecting, Igo. That’s you. You’re the slutty, addicted breeding bitch.” They continued their playful bickering, but Shiga couldn’t help but think about what had happened. He… gave birth to his mistress’ child. Through the huge, futanari cock that she gave him. His balls, still a little swollen, clenched as he recalled what a pleasure it was to have her seed fully dominate him, and though he’d never admit it to Ton…
He kind of wished she’d do it again.
