Brood Planet, Part 4 (Patreon)

A Story Prompt Tier for Spacebanana

Humanity is under threat of alien invasion, not that they know it yet. But this alien invasion is not interested in exterminating humanity, but simply turning its dominant species into enormous alien broodmothers to further their galaxial conquests. Unfortunately for 21-year old Allen and his family, that means big changes are ahead, and ones they might never be able to fully adjust to.

Brood Planet, Part 4

It was up to Allen and his mom Heather to take care of the rest of the family. It was not an easy task: given their increasing size, the growth of further limbs, and the fact that their prodigious egg sacs now had actual eggs inside them, it was a struggle. Allen helped drag his father’s unconscious body out into the fresh air in order to hopefully wake him, and he did his best to get him freshwater while the other former man slurred his words. Heather took care of Sarah, and to Allen’s surprise she was quite deft about it, despite the fact that with Sarah’s literally basketball-sized breasts, the daughter of the family was probably the heaviest among them. But as always, Heather was displaying a leadership and determination that the patriarch of the family had always lacked.

“There,” she said. “We just have to give them t-time.” She winced a little, and there was an audible gurgling in her pregnant belly. Allen tried not to think on how strange it was that his own mother was obviously heavily pregnant with alien eggs, and was increasingly full in the chest as well.

“I think - ahhh - that was another egg forming,” she muttered.

Allen nodded in understanding, caressing his own swollen stomach. “M-me too. I think the Zaar really are true to their word. We’re going to be broodmothers for the rest of our lives.”

Heather nodded, weary but understanding. “I think you’re right, son. I’m so, so sorry. I never wanted a life like this for you, not that I ever imagined a life like this. It’s the end of humanity as we know it. Your own father too, turned into a broodmare . . .”

She gazed over at the man, who was slowly coming to.

“Perhaps some other aliens will save us,” she suggested, “or the military.”

But Allen just shook his head. He had inherited his mother’s practicality and realist mindset, evidently ever more so than her own. “I don’t think anyone is coming, Mom. I think this is it. I think . . . I think this is our life now.”

There was a long, protracted silence. Heather blinked a number of tears back, remaining as stoic as she could be. But the new female hormones in Allen’s system flooded him a lot more powerfully, and he began to break down. With some effort, Heather shifted to his side.

“It’s okay, honey. Let it out. Let it out. It’s going to be okay.”

“N-no. It’s not! We’ve become a planet of alien broodmares! It’s insane!”

“We have to be strong. For everyone. Especially for Sarah and your father. I know you don’t always get along with them, but we have to try.”

He sniffled, nodded, then spoke in his much more feminine voice. “Okay. Okay. I’ll try.”

“Good. We need to stay a family. Even through all . . . this.”

She gestured to her bloated rear, her pregnant belly, even her humongous breasts. It made Allen laugh a little.

“At least we aren’t as big as Sarah.”

“Heaven forbid! My poor girl, she always wanted a larger chest for those social media trend things. Now, she has them. Quite the monkey’s paw, huh?”

Another chuckle. They continued to care for Sarah and Ethan as they woke, but by that point they were all tired. The makeshift tent and garage setup they had created would have to be enough. Heather took some time to awkwardly waddle her long egg sac over to the neighbours to help them out, and it was soon clear she was effectively the local suburb’s leader, making sure everyone had food, supplies, and so forth, as well as aiding them in creating their own outside and garage spaces for their bloated bodies.

By the time Allen finally fell asleep, hugging his aching, overly full dome, she was still out there. His sister sobbed a little into the night before falling asleep too, and it was one of the few times he was sorry for her. Evidently, her breasts were far sorer and heavy than anyone else’s. Allen could only sigh, and try to catch his own rest. After all, his breasts were sore too. He hoped they didn’t grow too much more.

***

The next day they each woke to further changes. The fact that more transformations had occurred was obvious from the very moment that Allen woke. He grunted, looking over himself, and for just a moment the whole notion of being turned into an alien egg laying female was just an absurd dream. But then his eyes opened.

All four of them.

“Holy shit!” he exclaimed, jolting instantly awake. “I’ve got f-four eyes!”

All four of them blinked together. It was astonishing: his vision carried more depth than ever, and furthermore he could see strains of colour he couldn’t imagine.

“Is that - am I seeing ultraviolet light?”

It had to be. He looked around, pushed open the flap of his makeshift privacy tent. Above the rooftops, extending from the antennae, streaks of red were also present. Well, red was the best way to describe them. They were sort of wavy, a colour he’d never seen before and so could not accurately explain.

“Radio waves,” he said. “Infra-red, too. This is crazy.”

He only just noticed at that moment how utterly female he sounded, even more than yesterday. There had been no recognising his voice as male then, but now it lacked even a slight huskiness or rasp. It sounded, astonishingly, like that of a gorgeous Hollywood starlet: a sweet soprano that clashed with his obvious bloated alien nature.

“Ughhh, fully female now. Sort of. Still have an internal dick for knocking myself up.”

He rubbed his belly, feeling the constant pressure behind it. It was larger than the day before, now a full beachball once more. He looked pregnant with twins, if not triplets, and close to full term at that.

“So f-fucking pregnant. OHhhh, and my tits!”

They were bigger, that much was clearly certain. The clothing he’d put on before he’d gone to bed was little more than a tight shirt to cover the top half of his belly and his new breasts, but it must have snapped off in the night. He hazily remembered something like that waking him in the night, before a ‘freeing’ sensation let his breasts hang where they may.

It was no wonder they’d pulled the fabric apart. They had to be overly-full F-cups by now, if not double-F’s. He only knew that size even existed due to some . . . extensive research when he’d been a horny teen. Now, having them on his chest, flushed and full and aching with the promise of future milk production for his alien young, horniness was the last thing on his mind.

“So f-fucking sore.”

He kneaded his breasts, tending to them. They gave a pleasant response, especially his fat, dark green nipples. His dark chitinous plates were absent where his mounds existed: there instead the skin remained that pale green. At least he had the mercy of his breasts resting on his stomach, though that too was its own curse. He most certainly looked full term with triplets now. In fact, quads may well be an apt descriptor. He grunted as he shifted his immense weight, thankful only a little that the Zaar aliens had seen fit to strengthen his legs to carry the burden.

He was just about to grab himself breakfast - his hunger was vast by this point - when suddenly an urge to push came over him. He squatted down, his second set of legs still too short to reach the ground. He tried to hold off the foreign sensation, but was unable to. The urge, the instinct, was simply too strong. He clenched all four of his bug-like eyes, widened his stance (his hips had become wider as well), and bore down.

“NGNHH! OOHHHHH!!!!”

One by one, a series of eggs pushed through his hips, squeezing through the birth canal that had grown into place there, and then plopped free into his egg sac causing it to bulge further.

“WH-WHY M-ME!!!? WHY US!?!?”

His pleas as he strained and pushed did not go unheard. Even through the discomfort, and the rising pleasure that was almost as unwanted, he heard his sister squeal in horror.

“NO! FUCK NO! WHY!?”

She stumbled out of the garage, where a hanging bed cover had given her some privacy. But there was no privacy to be had for poor Sarah anymore. She too had grown and changed in the night, and it was very clear where much of the changes had been directed. Like Allen, her belly had swelled, and like him she was flushed and sweaty as she tried to hold off another pushing session, birthing her eggs into her ovipositor. But while she was horrified over her eyes, which also numbered four now, and her still-growing second set of legs, it was very clear where her true attention was: her freakish breasts.

For a moment, Allen was confused. Yes, they were much larger than his, bigger than basketballs now, with massive nipples that were awkward for him to see. But they had not grown too massively. That was his reaction, until he saw her lifting them up. Her dainty hands were no match for her massive melons, her palms sinking into the flesh and making her moan in a way that Allen didn’t really want to hear from his own sister. But then he saw what she was appalled by, and why she was lifting her enormous boobs up: below them, small but evidently still growing, was a second pair of breasts. They were comparatively little, just normal-sized really, at least for a normal human woman. B-cups, likely. But against her J-cup or larger titties, they might as well as not have existed. Except they did.

“They grew in overnight!” she exclaimed, covering her nipples as best she could from his view, and failing - they were the size of large thimbles with areolas the width of miniature dessert plates now. “Have you grown any more?”

Allen shook his head. “They just g-got - ughhh! - bigger! I don’t have m-more of them!”

He bore down, strained as a particularly large egg squeezed through his hips. Were the eggs getting larger too? Even as his hips widened, they felt heavier, bigger, like he was being split apart. He orgasmed a little as it pushed against his sensitive inner walls, clutched his breasts. It was embarrassing in front of his own sibling, but then again, she had her own problems.

“Mom!” she cried. “Help me! This isn’t fair, why doesn’t he have extra b-boobs! It’s not f-UGUGGHH!!”

She began bearing down as well, and soon both siblings were pushing. Their parents joined, stumbling out, Ethan sobbing like he’d given up all sense of shame and self-worth, leaning against his wife as she tried to keep everyone calm.

“It’s okay, we’re a family,” she reminded them. “We’ll push together, okay? One, two, three, PUSH! NNGHH!!!”

“NNGHH!!”

She led the charge, and something about that leadership inspired Allen, and the rest of them. Even Sarah quit her moaning, managed to get herself under control. After a short while the new birthing effort was finished, and each of them had filled their egg sacs with perhaps another ten or so eggs, if not more. Allen looked at his family members and realised that while they all had rounded stomachs, it was actually him and his father who were more visibly pregnant than the women. Heather had larger breasts, perhaps as part of being a woman, and Sarah was beating them all in that regard, but somehow the men of the group - former men, at least - were the ones most filled with eggs.

“This is c-crazy,” his father moaned, his voice also now quite a high soprano’s, albeit much more whiny than Allen’s. We have to demand they turn us back! They can’t do this to us - they just can’t!”

The rest of the family, Sarah included, looked at Ethan with veiled contempt. Heather and he had a strained marriage, and perhaps Allen’s sister was finally seeing their father as less of a role model and more of the permissive, weak man he’d always been. Certainly, even Allen hadn’t realised how little power he had to step up. Heather had to carry his slack.

“Ethan, shut up! There’s no point whining. There are galaxy-spanning aliens. We don’t stand a chance. We need to eat breakfast.”

“B-but if we eat, we’ll ch-change! I’ll keep growing!”

She rolled her eyes. “We just have to accept it. At least try to live with it. I’m not letting my children starve.”

He crossed his arms across his naked chest, sulking. Sarah also sulked, though did not approach her father. As Heather set about getting food ready, and Ethan continued to whine in the background, Allen found his own space to examine his body. He was fully naked now, and no clothes would fit him, or any of them. He could feel his own member inside him, slowly building up more sperm to impregnate himself again.

“Fuck. I’m going to do that again, aren’t I?”

Thankfully, there was no indication yet of that happening. Allen looked out at the street and saw a number of individuals, neighbours they’d known their whole life, similarly struggling with their increasingly bloated, alien bodies. His nipples throbbed at the sight of Cindy Clyde several doors down who was breastfeeding her little toddler. The little baby was mostly unchanged, though appeared to have sprouted some antenna and a tiny ovipositor that it was giggling and laughing about. The tired, bewildered mother was simply thankful her infant was okay, and placed her against her breast to suckle from her. The sight seemed to flare up some instincts in Allen as well. A biological yearning to also feed his young.

“What are you thinking about?”

“GAH!” he rocketed to the right, causing numerous parts of his pale green mounds to wobble intensely. “Don’t sneak up on me Sarah, you scared the shit out of me.”

She rolled her eyes. “Bro, I did not sneak up on you. I’m heavy as a fucking house here. My tits are like half my old body weight. You were just lost in thought.”

Allen exhaled. “Yeah, okay. You’re right. This is all so crazy, huh?”

“Mega crazy. Fucking crazy. Insane as all shit.”

They shared a silent couple. He tried to ignore the strange sight of his sister’s prodigious bustline, just as she was trying to obviously ignore his pregnant femaleness. She bit her lip, clearly trying to communicate something.

“I’m sorry about the other night,” she finally said. “I shouldn’t have said all that stuff.”

He raised his eyebrows at her, shocked to hear her words. “Thanks,” he said. “I guess I was an asshole too. I guess it’s all small potatoes compared to what’s going on now, right?”

She nodded sadly, wiped several tears from her four eyes.

“At least we can see radio signals now?” he suggested.

It actually managed a chuckle from her. “Yeah, that’s super useful! Not!”

He laughed back, both of them sharing a bitter moment of humour.

“I’m growing extra tits, Allen.”

“I know. That’s weird.”

“Fucking weird.”

Another bout of silence. Without thinking, she began massaging her lower pair, and he had to look away.

“Oh God, I didn’t mean to do that! I’m sorry! They’re just so small, they’re getting squished by the upper pair. And it’s like - it’s like my body wants them to grow.”

He winced, and was about to say something a little cruel, until he saw the look of fear in his little sister’s eyes. “Yeah, it’s okay sis. I’m getting weird compulsions too. Apart from being hella hungry, I saw Cindy Clyde feeding her baby and, well, my boobs went all flushed. It was like I felt a need to start breastfeeding my own young, or something.”

He rubbed his huge stomach idly. It was full of pressure, and slowly growing. It had expanded another inch already, and he could feel another egg forming within it.

“Oh thank God!” Sarah said, and to his surprise she wrapped her arms around him, pulling him in tight. Their bare breasts squashed against one another, and hers were so large that his face was soon enveloped.

“S-sis! Sarah! I’m s-suffocating here!”

“Oh fuck, this is embarrassing! I’m so sorry!”

She released him, clearly having underestimated the sheer size of her gargantuan tits. They wobbled heavily, parting over her full pregnant belly, which to Allen’s annoyance was smaller than his own.

“What the hell, Sarah!?”

“What the hell? I was just, like, expressing that I was glad someone else felt like I did!”

“You just covered me in your tits, you fucking weirdo!”

She growled, stormed off in a manner that caused her ovipositor to collide against him rather deliberately.

“Weird fucking girl,” he said to himself. But even as he said it, he was hit with embarrassment. She hadn’t meant to make it weird. After all, they were technically both female now, sort of. And her tits were too big to really hug anyone without such a disaster happening. And she’d come to apologise to him and sort things out.

“Should’ve been nicer to her,” he said to himself. But that was when his stomach growled loudly, redirecting his thoughts towards food. “Fuck, I’m hungry.”

It would fuel further changes, and that terrified him, but as with several things, the compulsion to eat was overriding. To fuel further eggs, future laying, and future changes. His weak little secondary legs were only fifteen-inch stumps, but they were straining to grow further.

“OOhhh . . . food. M-must eat f-food.”

“It won’t be long!” Heather called. “For God’s sakes, Ethan, help your damn family.”

But Ethan was sulking in his tent, refusing to talk to anyone. Sarah was not sulking, but looked more despondent. They were all reaching their wit’s end.

“NNGhhh . . . n-need to eat n-noooww,” Allen whined. “P-please!”

“Still cooking!” his mother called. “I’m hungry t-too dear! I’m trying my - ahhh - best!”

But she suddenly stopped. They all did. A strange, warbling noise began on the horizon. The clouds parted above, and a great silvery UFO fly past at breakneck speed, causing the wind to briefly rush against them. A child cried out in fear somewhere. Ethan cried out to be rescued. But then the UFO passed.

THUNK.

THUNK THUNK THUNK THUNK

The entire family shrieked, Allen in a voice as high-pitched and girly as his own sister’s. A series of quite large canisters, roughly the size of miniature fridges, crashed into the ground in every front yard of the neighbourhood. Thankfully, they must have been precision-guided, because each landed safely on the lawn and not on anything or anyone. Theirs was rounded and chrome, and steam came off its edges slightly.

“What - what is it?” Sarah asked.

The answer came moments later. The top opened up, and a number of mechanical nozzles extended out like great tentacles, extending out to each member of the family. At the end of the nozzle was a suction cup of sorts, built to be enveloped by a mouth. A pink, oozing substance dripped from the one that came close to Allen. It smelled utterly divine. Like the greatest, sweetest, most nourishing taste he could imagine. The device whirred, and another voice of the Zaar spoke.

‘Hello humans. You are doing well to transform into pregnant broodmares. Already you are readying to birth our drones into the world, though you may notice some have more exaggerated or additional features compared to others. Worry not, your place in the hierarchy may be a little different, perhaps even blessed. Tomorrow, you will be fully evaluated to determine your suitability within the Zaar Galactic Empire, and your fecundity checked over. This nourishment will now be provided to you. It is the standard meal of our species, though yours is custom made to speed up your transformations and get your bodies working on producing more young. Congratulations future broodmares of the empire, and eat up! Yum!’

“I am not eating that!” Sarah cried.

“We can’t,” their mom said. “It’ll - it’ll change us.”

But both were licking their lips. Allen saw his father grasp the nozzle and place it in his mouth. “I can’t help it!” he cried. “I need food! I need it so bad!”

Once more the weakness of their father was exposed. Sarah looked at him with contempt. Even Heather did. But Allen couldn’t blame him. He seemed even hungrier than the women of the family. His womb was churning with a desire to make more babies. He was tired, exhausted, pressurised, and deeply pregnant. But there was no stopping the change to come. There was no chance at all, and he knew it.

Allen took the nozzle, and placed it against his mouth. The pink ooze entered his mouth, and he moaned in pleasure as he swallowed the delicious goo. Out of the corners of his eyes, he could see the others join in.

The next round of transformations and impregnations began moments later.
