Brood Planet, Part 5

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 5

The slop was beyond tasty. Beyond delicious. It was a food so intoxicating that none of them could go back. Ethan desperately drank from it, weak-willed and needy. But the others were little better: Allen began to drink deep from the nozzle, followed by Sarah, and finally Heather too. For as much as their mother wanted to resist, it was clear that even her biological needs had superseded her intellectual ones. And so they gulped down the substance, even knowing it would lead to further change.

It first manifested as a rising arousal. The family’s humiliation, each began to moan and groan as they devoured the delicious goo. Allen writhed, shaking his massive egg sac from side to side, causing his breasts to jostle as well.

“MMmhmmm,” he whimpered, feeling himself over. It was humiliating. He was naked, his insectoid broodmother body on display, and now he couldn’t help but touch himself. He squeezed his nipples, rubbed and caressed his breasts, even stroked his gravid belly. With his four eyes, it was easy to see out of his peripherals the fact that his family members were doing the same, especially Sarah. She had four breasts to contend with, and stroked them fanatically, shivering from their incredible sensitivity. It was all too much, and soon all of them felt their internal mechanisms begin to pump. Their impregnation had begun.

Ethan, as the first eater, was first. He stuttered, stopped eating the goo for just long enough to look utterly embarrassed. He whined in his high, newly-female voice, then began bucking his hips.

“Oohhhh G-God! Heather, h-help me! It’s h-happening again! AAGGGHH!!”

Heather looked at him with something approaching mild disdain. Already, she had joined him, bucking her hips which looked to be getting wider and wider. She moaned in a type of tone that Allen had never wanted to hear come from his mother’s mouth. Sarah followed, also providing a similar sound that embarrassed the siblings both. But he joined in not long after when the full internal thrusting began. He doubled over as much as he could over his gigantic, near-beachball sized pregnant belly, clutching it desperately as his body literally fucked itself pregnant again all over.

“OOhhh, s-so much! S-so much! P-pressure!” he cried. “I c-can’t take it! OOhhh . . . mmhmm! AAhh!!”

He stopped feeling self-conscious and gave in to the overwhelming pleasure. This was him now, he knew. An alien broodmother destined to make eggs, and while his internal male organ thrust into his own womb, that didn’t sound so bad. It continued to thrust, ram, slide into his moist depths, and all he could do was squeeze his huge tits and pray it would end soon, or not at all.

“Yes, yes! Oh God, yes! Fuck, yes! YEESSSSS!!!”

His penile organ erupted within him, and he recoiled as it splattered his reproductive tunnel with torrent after torrent of life-giving seed. It was hot, wet, and there was the utterly alien sensation of it sliding down the passage and into his womb, impregnating new eggs with life that he could then begin to grow and then give birth to.

“OOhhhhhhh,” he moaned, still overcome with the changes. Sarah also orgasmed, squeezing her four tits. As one could easily predict, strong-headed Heather held out the longest. Ethan had impregnated himself first.

But it wasn’t over yet. Even trapped in that post-coital pleasure, Ethan felt more than just his womb churn. His second pair of legs began to grow, extending out. The exoskeleton expanded, and he gritted his teeth as new tissue and matter formed, making the legs longer and stronger and capable of more easily carrying his increasing weight. The same changes were happening for the others, and their existing legs altered to more insectoid configurations too, with his spreading wider to centre his body. Allen also clutched his scalp as his antennae extended slightly. His pregnant belly surged forth, but it was his egg sac that truly took off. It grew and grew and grew, going well beyond its current fridge size. His stomach emptied, the fuel for this change disappearing rapidly, and for a moment he was filled with terror: he might actually die.

Quickly, he tried to reach for the nozzle. But it was too far away, and with his huge belly and now-swelling tits there was no way to manoeuvre himself. Even his new legs wouldn’t help him. He made a brief swat at the nozzle, but only succeeded in knocking it yet further away. It was beyond his grasp, and it was making him panic.

“N-need food! Need to grow! C-can’t s-sustain it without f-food!”

He tried again, but failed. Again, but failed. His body was beginning to hurt. His heart was starting to strain. Food, protein, calories, all of it was needed to fuel the changes, and if he didn’t have that fuel, his body wouldn’t be able to take it. His egg sac was blowing up, getting so heavy there was no lifting it off the ground at all. His head case expanded, skull lengthening with it. It was impossible to keep up with. All that mattered was the food. He needed it more than anything.

“P-please,” he drooled. “G-goo! Need good! S-someone!”

And then, suddenly, as if by a miracle, the nozzle lifted on its own. For a brief moment, Allen actually thought that it was just the alien technology, but when he looked to his left, he could see something in the air coursing from the nozzle. Or towards it. Something his new pair of eyes were capable of seeing.

It was coming from Sarah. From her mind.

Somehow she was able to control the nozzle with her mind. Even amidst her changes, she was directing it upwards, sending out beams of what could only be called psionic energy, lifting the nozzle up to reach Allen.

“H-how!?” he managed to stammer, even as his body shifted and altered and enlarged.

“I d-don’t know!” she cried. To their shared shock, she was growing a third set of breasts below her other two, and the middle and upper ones were still yet expanding. But despite this, her attention was on him. “I s-saw you in trouble, and I had to help!”

She gulped down more good from the nozzle.

‘And I reached out with my mind!’ she said, only this time, her mouth didn’t move. She was still eating. ‘Take it! Eat, brother! Eat, you idiot, because your body collapses!’

‘Okay!’ he replied, and grabbed the nozzle with his chitin-covered hands. He realised even as he took it into his mouth that he somehow communicated that mentally. ‘I can do it too! I can do it!’

‘Great! N-now just l-let me f-fucking grow all these extra goddamn tits in peace, alright? I’m becoming a freak here!’

‘So am I, but you saved me, S-Sarah! I’m s-sorry I’ve been such an ass.’

‘You have. But we’ve both god big asses now. God, this is insane. This is s-so fucking insane, and I’ve - OHHH!! M-MORE!’

Their talking broke down as the expansion continued. Heather and Ethan also changed. Soon they were all groaning and grunting and clutching and pushing and squeezing and moaning and orgasming and bloating and so on and so forth for minutes on end. It was excruciating and unbelievable, and yet none of them could quite help how deeply wonderful it all felt. It was wrong, so damn wrong, but they all felt as if their changes were nearly done.

They continued to eat the goo, guzzling it down to help fuel their changes. It was Heather that first managed to speak again.

‘Don’t forget to eat your food, kids!’

Everyone groaned at her joke. But somehow, it managed to buoy them up a little.

‘That was awful, Mom!’ Sarah thought. ‘Just tacky! God, I almost want to post that on my socials.’

‘I have to agree with my terrible sis,’ Allen thought to them, ‘that was bad. Not even Dad would make that joke.’

‘Well, I was proud of it.’

Ethan groaned. ‘Stop joking around! Someone help m-me here! I’m growing eggs. The aliens need to help me! Hello! HELLO! Change me back!’

‘SHUT UP DAD!’ the two siblings thought-yelled. Heather joined in as well, not even calling him ‘dear’ or ‘honey’ as she often did. The whole experience was making very clear exactly what kind of husband father Ethan was when the going got tough. So instead, filled with shame, the insectoid broodmother that was Ethan simply silenced himself, and continued to bloat up with eggs.

They all did, for a good number of hours to come.

Finally, the family was full. Everyone in the neighbourhood was, in fact. There was quite a lot of embarrassment as they looked over each other’s changes, and their own. All over the neighbourhood and down the street one could hear expressions of shock, dismay, anger, frustration, even amused boasting or sarcastic comparisons being made between couples or siblings.

Allen’s family was no exception. The latest bout of changes had been enormous, changing them to become what they could only hope was their final forms, lest they get any bigger. Their bodies had even diverged somewhat, looking a little unique, with Sarah being the most identifiably different of the group. The former thin, attractive girl that irritated Allen so much as a shallow sister was now the very un-proud owner of six very large breasts down her front. The top pair were easily the size of basketballs, perhaps just a little bit grown from earlier that morning. The middle pair were nearly equal in size, and were perhaps still growing to reach that point. The lower pair were easily F-cups or even G-cups, and looked compressed by the others. Sarah continued to knead and adjust them awkwardly, as if almost urging them to grow to get some relief from the weight of the heavier breasts above. She was having more success than perhaps she ought to, and that was because of the other strange development to her body: she now had an additional pair of arms, nearly fully grown, and with a third pair also developing.

“It’s so fucking weird!” she whined, obviously overcome by the amount of limbs she now possessed, and still learning how to coordinate them. “God, it’s sooo fucking gross!”

The fact that she was also developing what looked like additional breasts along her egg sac was also something that was worrying her, and the rest of the family. But no one mentioned it, least of all her. Six breasts was enough, particularly given that they had started seeping a milky green fluid, slightly darker green than their pale lime flesh, but undeniably milk nonetheless.

“Fuck! It won’t stop! This is awful!” she cried. ‘I hate this! Why am I more of a freak than anyone else!?’

‘It’s okay honey,’ Heather reassured her, as she was doing so with many members of the neighbourhood. ‘It’s going to be okay. We j-just need to k-keep together, okay?’

They once more slipped into psychic discussion, something they were already doing with an unusual regularity. Given how much food their bodies needed, and the never-ending amounts of pink ooze to consume, it at least made talking easier. Heather petted her daughter along her back, giving comforting words through her mind, even as she was forced to crease her brow and push more eggs to her ovipositor.

Allen’s Mom had also diverged a little from the others. She looked a bit bigger - not in the egg sac, but all over. As in, her limbs, her torso, her head, her arms and so forth, were all literally bigger, like she’d been supersized. It was not a totally subtle difference. If her torso was still on human legs, she could well be said to have grown a full two feet in height, if not more. It was a startling change, and one that only cemented her unofficial role as the leader in the community. People who had already looked up to her were now doing so quite literally as well.

“You’re going to be fine, Sarah. We’ll adjust. We’ll all adjust. Just look at me, right?” Your giant mom!’

Sarah choked on her tears a little, nodded. “Th-thanks. That’s a big help. Literally, lol.’

‘Now honey, you know how I feel about you saying ‘lol’ as if it is a word.’

“Fiiiiine. God, end of the world and growing extra tits and I can’t even say made up words.’

Heather chuckled, and Allen joined her. Sarah was still upset, but the good thing about their altered bodies was that they were so busy making alien eggs and reimpregnating themselves that it was difficult to latch onto depression for too long. Heather was handling it best, and with her larger size and much greater crest and antennae, it was becoming increasingly clear that she could communicate across much greater distances, coordinating not just the neighbourhood’s relief efforts but those of the surrounding neighbourhoods as well.

‘I can’t quite explain it,’ she communicated telepathically. ‘It’s like I’m much smarter, and can carry on several conversations at once.’

“How many people are you talking to right now?” Allen asked

She winced a little, and he could see numerous signals bouncing back and forth from her head: radio signals.

‘Twenty seven,’ she said. ‘Twenty eight now.’

“Holy shit.”

‘Language.’

But while she was handling the horror show as best as she could, Ethan was just the opposite. He was freaking out as much as before, if not moreso. Part of that was his complete immobility. While the emergence of psionic powers had allowed each of them to move a little easier - after all, with a bit of practice, they were already finding instinctive ways to lift their egg sacs a little - Ethan had no such mercy. To his absolute shock, his limbs had actually started to withdraw, arms included. His belly had bloated lower, conjoining to his egg sac as if they were fusing to become one giant chamber. For what, no one quite knew, least of all Ethan. Everyone tried to help him, but he was almost catatonic with frustration and shame, and it was clear that whatever he was gestating, it was going to be bigger than the regular eggs the rest of them were making. His exterior was constantly sweating from the strain.

All of that left Allen himself. He didn’t have the many milkers of his sister (thank God) or the tall height of his mother or the immobility of his father (thank God again). What he did have though, was eggs. Lots and lots of them. They were gestating at an astonishing rate, which meant that his behind was growing alarmingly too. While Sarah complained of her milky breasts, and Ethan complained of everything, Allen was complaining about the fact that almost every half hour or so he was overcome with the incredible urge to push newly developed eggs from his belly into his ovipositor. It was a damn good thing the skin could stretch, and that he was practicing his psionic ability to take the weight off of his egg sac, because it was very, very obvious that he was the most fertile and productive broodmother on the block. The sheer, agonising fullness of his rear abdomen almost made him wish that he could just hurry up and give birth to these eggs already. It was an insane thought, really, but the fact was that he felt like he would burst if he didn’t push them. New ones were constantly being added to the spacious egg sac, but there was only so much room, even if the sac could stretch a great deal.

“UGghnnn!! Have to p-push again!” he gasped as that very need overcame him.

“Again? Seriously?’ Sarah communicated in part-speech, part-psionic talk.

“It n-never stops!” he gasped. ‘My belly feels like it’s on f-fire. Like I’m never not making eggs.’

‘Gawd, if that’s m-me and milk it’ll be just as bad!’

“Well, at l-least you started as a girl! I’m s-stuck making f-fucking alien babies!”

“Let’s just both agree this s-sucks, hard,” Sarah suggested, squeezing her boobs in a now-familiar way with her two pairs of arms. Allen tried to look away, but to be fair, he was doing the same to his own bloated tits every time he orgasmed from pushing.

“Oh God! I’m c-coming! It’s h-happening!”

‘Gross!’

“Sh-shut up! I c-can’t help it! You were moaning when you were dripping everywhere before, S-Sarah!”

That was enough to shut her up. Still, after she had helped him, and approached him earlier, he’d tried to be nicer to her. The bickering didn’t stop, but it was more gentle-hearted now, even among the alien chaos. With one final push, Allen managed to squeeze the egg through, followed by two more, both of which filled his ovipositor to near total fullness. He gasped, his huge, overly-tight body trembling, and took to rubbing his egg-filled stomach just to soothe himself. He noticed Sarah doing the same, only it meant she caressed her many breasts, causing her to shiver.

“Jesus, can this get any weird?” she asked.

It was tempting fate, because at that very point, a UFO flew overhead, slowing until it hovered several hundred feet above their suburb. Everyone gasped, from their next-door neighbours to the couples up the street, to the still-cowering Ethan whose body was starting to look more like a giant, increasingly-limbless worm that Heather was doing her best to try and serve, despite his whining.

The UFO hung in the air for thirty seconds of rising tension before, finally, a voice spoke in that feminine warble they were now used to.

‘Attention former humans. Congratulations on becoming fully fledged members of the Zaar Galaxial Hive! You are now officially part of our extensive species, and you will soon bear the clutches of our many, many millions and billions of soldiers, scientists, farmers, producers, labourers, servants, administrators, record-keepers, so on and so forth. This is your role now, to be the broodmothers to keep up our economy in this section of the galaxy, and you will do a fine job of it on this new broodworld. Over the next few hours, we’ll be canvassing those with different mutations from the rest and assigning you your elevated roles. If you have additional body parts, strange aberrant growths, or simply exaggerated dimensions, then congratulations! You are going to be examined, studied, and given a special place within our hive. We look forward to helping you be the best broodmothers you can be.’

And with that, the message ended, and the family looked to one another.

“Um, doesn’t that message apply to a-all of us?” Allen asked.

There was silence in response, and a rising dread. The urge to push came over the transformed former male, and he pushed through more eggs.

Certainly, the amount of egg production in his body was aberrant enough to join the rest of his family. Soon, they would all find out what their additional changes meant for them.
