Altair Guardians: Chapter 7 - A School Gone Mad

“Ah, ahhhh…ahhhhn! Please, I-I can’t take any more of this! Ahh!!”

At dawn, the Mizuno sisters’ sexual moans echoed through their house.

Altair Rose wore her red costume while she shook in bed. Altair Marine had her pinned down and pressed a loudly vibrating massager against her crotch.

A week had passed since their humiliating defeat to a group of ordinary people. After a night out having sex with random men, the heroine sisters would return home and have sex with each other until it was time to go to school. But their relationship had changed after that day a week before.

“Wait, Marine! Ahh! I-I’m going to cum!”

Rose squirmed in her costume that still reeked of cum. She raised her arms, exposing her armpits, clutched the sheets, and clenched her teeth. She repeatedly kicked at the sheets with the toes of her boots and sometimes kicked vainly at the air.

“You’re going to cum all on your own again, Rose? You really are a pervert! You need to build up a greater tolerance for pleasure.”

A sadistic light shined in Marine’s blue eyes and she derived pleasure from watching her sister moaning and writhing like this. She switched the massager to max power, causing Rose to scream and convulse while a shower of love juices squirted from her.

“Hearing you moan like that turns me on too, you know? So when you give in, it makes me give in too. This is to punish you for that!”

“Eek! P-punish me? Punish me!? Ahhhh! Don’t punish meeee!!”

Rose’s legs kicked wildly at the masochistic pleasure squeezing her chest when she heard that sweet word: punish.

Every single day they would soak themselves in the semen of ordinary people and then do more pleasure training back at home. They were even showing results. Every man exposed to their costumes and skill would ejaculate so much sooner than before, so they knew they were growing stronger by the day. This was backed up by how they almost immediately ended any battle with the Hypnos during the day. They had learned how to milk the Hypnos in record time.

But their tolerance for pleasure was much less promising. The city’s men already knew the two of them were masochists, so no matter how well they milked the men to start with, the men always turned the tables on them in the end. Rose’s masochism was especially bad, so she would climax in no time at all. Then Marine would get wet from hearing her sister’s moans and the men would use that opening to get at her too. She was so dominant when milking the men or helping Rose train, but once she was on the receiving end, she was little different from her sister. She would always leak love juices until she had lost the power to fight. It was the same thing every single day.

Each night, they would trudge home exhausted, but Marine would still be fired up and unable to contain her desire. Yes, she could not put out the dom flame inside her until she had made her sister orgasm and orgasmed herself while watching it.

“Onee-chan, I warned you I would have to punish you if you let them make you cum again. If we keep letting that happen, we aren’t heroines anymore. We’re just a pair of sluts.”

Marine slapped Rose’s thigh and indulged in the sadistic pleasure racing up her spine.

“Eek! I-I’m sorry,” said Rose, weeping. Nothing turned Marine on as much as her sister’s usually strong and beautiful face distorted by this kind of masochism.

“Admit it! You’re just a slut! You don’t deserve this costume!!”

Marine smiled as she shouted at her sister and reached for her transformation suit. Their costumes were usually stripped from them, but fortunately, they hadn’t been this time.

“No! Wait! Not my costume! Kyahhhhhhhhhhhhhhh!!”

Marine tore Rose’s body dress and inner suit straight down the middle, baring her upper body and leaving only the hole-filled pantyhose on her lower body.

“Ahh! My suit…my costume!” shouted Rose.

Her pink nipples had been such a modest size just three weeks before, but after soaking up so much grunt semen and being pleasured through so much masturbation and sex, she now had slutty nipples the size of a thumb tip. Marine gave them a look of scorn. When Rose noticed, she moaned “No, don’t look at me like that!” and covered up her nipples. But the touch of her gloves provided pleasure, sending a tremor through her, so she started stroking her nipples without thinking. Marine snorted and reached for her own hip.

“Ahn, you are so adorable. Now, I think it’s time for the finishing blow.”

She drew her Marine Blaster and showed it off to Rose.

“N-not that…a-anything but that,” said Rose, shaking her head.

“Request denied.”

Marine smiled and gathered energy in the blaster’s tank. But she didn’t stop there. She pressed the tank against her own crotch and let her love juices flow inside.

Once her energy and love juices were mixed together in the tank, the blaster’s muzzle glowed with a sexual pink light. She did not hesitate to stick the end of the gun into Rose’s pussy.

“Ah, ahhh.”

Rose gasped and Marine pulled the trigger. The blaster shined bright and released several energy-filled bubbles into Rose’s vagina. They spread her vagina to the limit before bursting all at once.

Several popping sounds came from her crotch.

“Ah, gah! Ahh…ohhhhhhhhhhh!! I’m cumming, cumming, cumming!!”

The bubbles were mixed with Marine’s sexual desire, so they popped gently inside Rose’s vagina, filling her with pleasure and bringing her to climax. Rose was helpless to stop the powerful orgasm that stiffened her limbs and pushed her hips up from the bed.

The climax juices were soon followed by a golden liquid flowing from her hairless pussy. Marine let all those juices soak her while she cried out in unbearable pleasure.

“Ahhhh! Onee-chan! That’s what I wanted to hear! Yes, I’m cumming, I’m cumming toooooo!!”
Marine climaxed while her sister squirted and pissed on her.

“Marine…Karin!!”

Rose reached out her hands and Marine held them tight. Marine dropped her gun and collapsed on top of Rose. Finally, they held each other in their arms while trembling from their orgasms.

 

“We need to get to school,” said Marine after checking the clock.

After pleasuring each other and masturbating in front of each other, it was time to leave before they knew it. Only now did they dispel their transformations. They used their Altair Energy to soothe their weary bodies and even eliminate the need for sleep. After sharing a shower, they left the house.

But before they left, Rena begged her sister like she always did.

“Karin. I want to train during the day.”
“Yes, I know. I’ll give you a really powerful one today.”

Karin smiled at the way Rena stuck her butt out for her, so she pulled out two egg vibrators and stuck one in Rena’s vagina and the other in her anus. She slapped her moaning sister on the ass, told her to stop moaning, and placed a dildo and vibrator in her own school bag.

“We need to train at school too,” she said with a sadistic smile, holding up the bag containing the sex toys.

They had been training like this for several days now, using the tension and guilt of knowing someone might notice.

But they had no idea what was in store for them at school today.

 

After school, the boys on the swim team arrived at the pool before anyone else, gathered in a corner of the pool, and spoke to each other with a somehow empty look to their eyes.

“They’re here.” “Just like always?” “Yeah, dressed all slutty.” “I can’t wait any longer.” “Ha. They’re asking for it dressed like that.” “Wait a bit longer. We can make our move once practice is over.”

The boys were staring at the door to the girl’s locker room. And that door was just about to open.

 

“Huh? Where are the others?”

Karin tilted her head after noticing all the other girls on the swim team were missing.

“None of them said anything about missing practice today,” said Rena, sounding puzzled.

The boys were here, so the sisters assumed the girls would arrive before long and began their stretches. They felt the boys watching them more than usual.

“Do we look weird?” Rena looked down at her swimsuit.

“I don’t think so,” replied Karin.

The boys had good reason to be staring. While the sisters thought of it as perfectly normal, the boys didn’t see it that way. The two of them were not wearing racing swimsuits or even school swimsuits. They were wearing slingshot swimsuits that only barely hid their nipples and crotches. Plus, these were too small for them, so they dug into their large breasts and butts and nearly left their labia visible.

Their barely-covered bodies created a sexual atmosphere, but they performed their stretches like nothing was amiss.

The boys stared intently at the sisters like hungry animals. They could tell the cloth digging into the sisters’ crotches was sticky with love juices.

 

“The others never showed up, but I don’t sense any Hypnos around. I wonder why.”

“Ahh…nh, ahhhhn! I-I don’t know…ghhh!?”

Practice was over and the colors of evening were creeping into the sky. After changing back into her uniform, Rena returned the egg vibrators to her pussy and ass, making her moan in what sounded more like sobs. Her pussy was already dripping with sweet juices and her nipples were so erect they formed noticeable bumps in her shirt.

When the two of them stepped out of the locker room, the boys approached, still in their swimsuits. The boys’ eyes were directed at the sisters’ bodies.

They looked so sexual. Their hair was alluringly wet and they hadn’t dried off from the pool, so their shirts clung to their bodies and let the color of their skin show through. The lack of a bra meant their nipples showed through too, so it was impossible to miss that their nipples were stiff with arousal.

The boys gulped, but the sisters were oblivious to their presence and began to leave while being overly intimate for sisters. Karin kept reaching out and rubbing Rena’s nipples.

“Ahh…d-don’t touch me there, Karin.”
“Onee-chan. Hee hee, you’re so cute when you blush. You need to resist this kind of pleasure, remember?”
The boys clenched their teeth at the girls’ behavior. They breathed heavily from the nose and the veins bulged at their temples.

“What are you two doing?”
The sisters’ reacted in surprise when the boys addressed them. They had been so focused on their “training” they hadn’t noticed the boys approaching. Uh, oh, they thought, quickly separating from each other.

They couldn’t let anyone know they were training their pleasure resistance with Karin in the dominant role and Rena in the submissive one. They feared that would give away that they were the Altair Guardians who milked the Hypnos and fought against pleasure.

“U-um, you misunderstand.”

Karin smiled and shook her head. Rena’s hips were wiggling from the pleasure in her ass and pussy, but she kept a straight face to try and hide it.

“Th-that’s right. This is just normal sister stuff.”

But their attempt at an excuse was like oil on the fire. Their revealing outfits were unusual enough on their own, but calling the nipple teasing “normal sister stuff” just made them sound promiscuous.

“That’s it. I can’t resist anymore.”

“Kyah!? Wh-what are you doing!?”

“Hey!! L-let go…ahh, what’s gotten into all of you!?”
Karin shouted and Rena was confused when the boys grabbed them and dragged them to the poolside. They were the strongest girls on the planet when transformed, but they were as helpless as bunnies before transforming. Rena and Karin were laid on the poolside where they groaned.

They held each other in their arms and looked up at the boys in consternation. The boys glared down at them in a way they had never done before. But the sisters had seen those same looks countless times while transformed, so they knew exactly what it meant. But as much as they were used to it while transformed into the Altairs, they couldn’t understand why it was happening now.

Their hearts began to pound with a sexual rhythm, but they felt more confusion and disgust than arousal. Karin began to tremble and Rena held her arm protectively in front of her.

“You can’t just dress like sluts every single day!”

“Wh-what are you talking about!? This is normal! What is wrong with you all!? What possible problem do you have with our clo- ah! Noooooo!!”

“Kyahhhhhhh! Let go! No, noooo!!”

The beasts’ claws reached for them before they could say anything more. Their legs were grabbed and spread wide. Their ultra-miniskirts did nothing at all to hide their hairless pussies from view.

“Ahh! No, don’t look! No, noooo!” shouted Rena.

She and Karin tried to resist, but they couldn’t overpower this many boys without transforming.

“I knew they weren’t wearing panties. No bra either.” “Sigh, I can’t believe you were both such sluts.” “Check out Karin’s pussy. It’s so hot.”

Rena at least had her pantyhose, but Karin had nothing to hide her crotch from the boys’ eyes. She wept in disgust and embarrassment and begged them to stop, but that only fired them up more.

“If you expect us to believe you’re not sluts, then prove it. We’ll stop if this doesn’t do anything for you,” spat a boy Karin had always thought of as a friend.

He pulled over a hose hooked up to a faucet and turned it on full blast. The water erupted out and hit the concrete floor with a sound like a whip.

“No, s-stop! Kyahhhhh!!”

He targeted Karin first. The water current struck her labia with the accuracy of a sharp sword. The splashing water soaked her entire body.

The shock to her pussy made her scream and twist her body. But the beasts with glittering eyes pinned down her limbs to keep her from escaping.

Her body shook on the concrete. She cried out and twisted in protest, but a change soon came over her voice. Only Rena noticed the change. They were both sensitive to pleasure from any kind of stimulation even when not transformed.

“W-wait! Leave Karin alone!!” shouted Rena. “I-if you must do it to someone, do it to me!”

She was truly motivated by a desire to protect Karin. Both she and Karin failed to notice how strange it was to ask to be tormented herself instead of just begging them to stop altogether.

“Oh, we’ll do that too.”

A laughing boy approached and Rena paled. A torrent of water burst from a second hose and hit her in the crotch.
“Eeeeeeeeeeeek!!”

She screamed. The pantyhose was only a very thin layer. Plus unlike Karin, Rena had vibrators in her pussy and ass. The tension and disgust of the scene did nothing to prevent the unbearable pleasure brought by her abnormal sensitivity.

“See, you like it. You are sluts!!”

“W-we do not like it! W-we…ahhhh!!”

“That’s right! We…eek!! Ah, ah…ahhhn!”

They both shook their heads to deny it, but their shoulders were trembling and their cheeks were red. More than that, the stiffness of their nipples was plain to see with their wet shirts clinging to their skin.

“Don’t lie to us. Hm, that pantyhose is in the way.”

“Ahh, ghh! W-wait! Don’t tear my- ahhhh!!”

The crotch of Rena’s pantyhose was tugged from both sides. The force of the water and the boy’s fingernails were too much for an ordinary garment which was not part of her transformation costume, so it tore.

“N-no! They’re coming out!!”

(W-wait! I don’t want this – I really don’t – but if you do that- ahhh!)

The tragic heroine wept at knowing how this would activate her masochistic side. She couldn’t last any longer. Her pussy opened up and her ass went weak. The cold water sprayed in through her torn pantyhose and her secret was revealed before the boys’ eyes.

“Nooooooo! Don’t look, don’t look!!”

With a lewdly sticky sound, a pink egg vibrator left her crotch. Then an identical thumb-thick device popped out of her ass. The wireless sex toys rolled along the ground, dancing madly from their intense vibrations.
“I fucking knew it!” “Yeah, I’d noticed a weird sound coming from somewhere during class.” “I couldn’t believe they would go this far, though!”

The boys’ breathing grew heavier at learning this girl went about her everyday business with vibrators inside her.

Rena was more concerned about having the details of her “training” revealed and she screamed in greater embarrassment than when fighting. Fortunately, no one here could link this action to the Altair Guardians, but they still thought she was a slut who wore vibrators to school. She couldn’t tell them this was necessary training to fight back against evil, so she could only writhe in embarrassment as they gave her looks of scorn and lust.

(N-now they know I had a vibrator in my pussy! B-but this is training! It’s to help me fight and preserve the peace!!)

She could make that excuse all day long in her mind, but she couldn’t say it out loud. No one knew they were the Altair Guardians. That was their secret.

After seeing this “proof” of the sisters’ sluttiness, the boys could not stop themselves. Their hypnotic suggestions made them see these two as more beautiful and sexual than anything they had ever seen.

“Hey, does Karin have something in her too?”
“Eek! Don’t spread my pussy!!”

“Did you hear that? She said ‘pussy’.” “Holy shit.” “I didn’t think these two were like that.”

The boys discussed what they were seeing while grinning and spreading Karin’s vagina wide. Then they sprayed the water inside, making her squeal like a pig.

“Nothing here. Or in her ass.”

She trembled in embarrassment as they checked both holes. Despite her best efforts, her body heated up.

“Ahh, s-stop that! Don’t touch Karin! Ahhhn!”

“Shut up. We can all hear you moaning!”

Rena shouted several times, but she was more sensitive than Karin and couldn’t stop the fire ignited within her.

“Looks like Karin doesn’t have anything. No underwear, but that seems downright reasonable compared to Rena.”

“Hey! Let’s not jump to conclusions. Looks like Karin’s a slut too!!”
One boy triumphantly held up Karin’s sports bag. Karin’s eyes widened and she gasped: “N-no, don’t look in there.” The boys grinned at her reaction and dumped out the contents of the bag.

“Whoa, what the hell!?” “Ha ha. That’s quite the collection!”

A pile of adult toys fell to the ground: a powerful electric massager, SM clips, egg vibrators, and extra-large dildos.

“Care to explain this, Karin? Do you use them to get off!?”
A boy thrust a toy in front of Karin’s face and questioned her about it. She shook her head. Her thoughts were drowned out by panic at having her secret found out. She couldn’t tell them she used those to train Rena’s resistance to masochistic pleasure, increase her own skill at providing pleasure, and teach herself not to feel too much pleasure from taking that dominant role. She had to hide that they were Altairs, so she tried to find another excuse. But she was so panicked, she ended up blurting out the first thing that came to mind.

“Wh-what’s wrong with carrying those with me!? They’re just to use on my sister!!”

“What the shit!?”
Her answer was so far outside the norm it left the boys speechless. It also aroused them. The fronts of their swim trunks were bulging and showing off the shape of their erect cocks. The young penises gave off a youthful smell different from what the sisters were used to. They were so aroused a few of them had already cummed in their swim trunks, but they never seemed to run out of lust or cum no matter how much they ejaculated. The sisters were just that erotic to them.

“Ahhh, ahhhh!!”
(Wh-why would you say that, Karin?)

Meanwhile, the horny older sister writhed on the ground at Karin’s statement. Her hips hopped up several times as she was reminded of the sweet but intense way Karin “trained” her with those toys. Juices far stickier than the water began to join the water puddling on the ground.

“I see. So Rena gets off to being dominated, does she?”
The boys all lowered their swimsuits, revealing their rock-hard erections. They tossed aside the hoses and let go of the sisters.

“Hyah!”

“No, p-please stop!”

Rena and Karin were no longer pinned down, but they still couldn’t escape. The hoses had left their hips too weak to move.

“Ha ha. You want these, don’t you? I mean, you dress like that, you have vibrators in your ass and pussy, and you carry an impressive collection of sex toys around with you.”

The boys had entirely lost control, approaching as lust-mad beasts. Rena and Karin’s eyes were glued to their erect cocks and they gulped. But a moment later, a powerful light grew in their eyes.

Just like the light in the Altair Guardians’ eyes.

“Kh, hhh! W-we do not want those! Stop this immediately!! We won’t let you do this!”

“That’s right! You will not, hhh, get away with this!!”
Rena and Karin felt an unbearable sorrow. Boys they thought they had known seemed to have transformed into someone else entirely. Yet they were acting of their own free will. Was this what happened to human nature when supplied with too much desire? Were the Altair Guardians fated to be raped by the victims of their enemy? But worst of all was how their own bodies reacted to the boys’ sexual desire.

(Ahhh! Why is this happening?)

The heroine sisters wept in their hearts as the males and their own body’s pleasure mercilessly attacked them.

“Heh. Say what you want, but this down here is telling a very different story.”

“Ah, ahhh!!”

Rena bit her lip, but the sweet pleasure attacking her entire body forced her mouth open and sent out a lovely masochistic moan for the boys to hear. A penis brought to full erection by the sight of Mizuno Rena in a wet uniform was shoved inside her vagina with no foreplay.

“Ahhhhhhhhhn!!”

She moaned loud, exposing her pale throat. The boy was right. No matter how much her mind protested, her body betrayed her by shaking with pleasure. The heroic part of her that wanted to resist this cruel violation lacked the strength to move a finger or even suppress her voice. An indecently loud moan of pleasure left her mouth as she was penetrated with the force of an animal in heat.

“Ohh, god yes!! Rena’s pussy is so fucking tight! And it’s pulling my dick in deeper. Gh, I-I can’t even pull it out!!”

Her female hole was more than ready to take a male inside. Once the penis was inside her, her inner flesh squeezed and produced sticky love juices while pulling it toward her womb. This pussy could make experienced Hypnos grunts cum in no time, so even though she was untransformed, the boy wasn’t going to last long. Especially when he had already been close to exploding just from seeing those two so full of erotic hormones.

“Khh! I’m cumming!” shouted the boy less than three minutes after entering her.

“Noooooo!! Don’t cum inside meeeee!! Eeeeek!!”

Rena screamed as the manly cock released all of its semen. Her legs stiffened and kicked at the air as she felt the ejaculation. Her disgust and resistance were enough to keep her from climaxing, but she doubted that was going to last much longer.

“I’m next!!”

Once one boy was done, another boy would rape her. Plus, the one who had just finished was hard again in no time and masturbating to her poolside moaning.

“Eeeeek!!”

Rena’s cries echoed across the pool.

“Noooooo! Stop, ahhhh! G-get that out of me!!”

Rena’s screams were joined by Karin’s cries. She already had a penis inside her too, but she had something Rena did not.

“You claim you like to dominate your sister, but you’re quite the masochist yourself, Karin!” shouted the male pinning her down and thrusting his hips like a crazed monkey.

The smaller sister’s uniform looked extremely fetishistic with her skin showing through its wet material. The nipples at the peak of her large breasts were especially noticeable and they now had the SM clips from her bag attached to them.

“Ow, that hurts!! Please stop this!!”

(M-my nipples are on fire! It’s incredible!! I-I r-really like this! No, I don’t want to like this. I-I need to resist it.)

Initially, she had kept a strong face, insisted she didn’t like this, and demanded they pull out, but with the powerful clips on her nipples, her face melted more and her speech slurred more with every thrust. She didn’t want to give in any more than her sister, but she was always hopeless once someone else took the dominant role. She had trained her body to milk males, so it rejoiced at the cock inside her and desired its cum.

“Ahhhhhhh!! Y-your cock is so deep!! Wait, why is it twitching like that? Ahh, are you going to cum inside me!? S-stop, you can’t!”

The erection pushed its full length inside her and then trembled in the deepest part of her vagina. She had felt this precursor to ejaculation countless times. She struggled to try and resist it. Or she meant to. In reality, the slightest movement sent a tingling sensation through her nipples that sent sparks flying before her eyes and sapped her strength.

“You’re clearly enjoying this, so like hell I’m stopping!! I’m gonna cum inside your pussy!!”

The boy cried out in pleasure while releasing his semen from the penis kissing her womb.

“Ahhhhhhh! S-so much sperm! Inside meeeeeeeee!!”

Karin shouted, shed tears, and shook. She felt pathetic for failing to resist, giving into the pleasure, and letting him cum inside her. But the feeling of that burning magma filling her vagina was so wonderful she could never get enough of it. She clenched her teeth and widened her eyes to try and resist orgasming, making her look hopelessly pathetic and erotic.

“You could use a pair of these too, Rena!!”

“Eeeek!! Not the clips!!”

The rape did not end there. Rena had clips added to her nipples as well. Powerful springs sank the jagged metal fangs into her sensitive flesh. She was an even greater masochist than Karin, so the pleasure was unbearable.

“Ahhhh! No! If you cum in me like that…I-I’ll get pregnant!!”

Rena wept and begged them. When transformed, their holy Altair power eliminated any risk of pregnancy, but that didn’t apply now. If the boys continued to ejaculate inside them, there was a risk of pregnancy.

“Then have my baby, you slut! Your tears can’t mask that pleasure! Fuck, your pussy is good!! I’m cumming!”

“Ah, ahhhhhhhh!! It’s so hot!!”

The hip-thrusting beast released his cum. She had lost count of how many boys had cummed inside her now. Masochistic pleasure rose within her and her jaw pulled up.

(N-no! I want to cum! I want to cum so bad!! Ahh, I-I can’t resist it!!)

The back-to-back creampies were bringing her to her limit. No, she had already reached it. It was only her mind’s resistance that had kept her from orgasming already. In an Altair battle where it was her duty to be penetrated, to milk semen, and to accept the pleasure, she would have experienced a light orgasm from the spraying water and cummed like crazy as soon as the first cock was inside her.

“Ahhhhhhhhhhh!! Not a clip on my clit too! Ghh, stop, don’t cum inside me again! Help meeee!!”

But neither Rena nor Karin could resist much longer. Karin screamed when a clip was attached to her erect clitoris. Rena tried to reach a hand out to her sister, but when a clip sank its fangs into her clit too, she screamed and her limbs stiffened.

“D-don’t be – nhhh! – mean to Karin!”

Drool dripped from the corner of her mouth and her face melted as she moaned, so her demand did nothing to stop the boys. They only sped up their thrusting hips.

“Here, we’ll let you comfort your sister.”

Instead of pinning them down, the boys shifted to the cowgirl position with the sisters facing each other. Now they could see each other’s melted face while they moaned.

“Ahhhhh, stop, please remember who you are!”

“Noooo, Onee-chan, I, I’m going to…ahhhn!”

The sisters could only moan while the boys below them thrusted roughly up into their pussies. The change in position also changed what part of them was stimulated by the thrusting. The frenulum rubbed against their g-spot, providing a frustratingly weak pleasure before the tip directly struck their cervix. Their inner flesh squeezed and produced more female drool in response to the new sexual attack. They shook their heads to reject what they were feeling, but their pleasure wasn’t just obvious to the boy feeling their pussy squeeze. Everyone looking at them could tell.

“Huh, you’re still not cumming? Then how about this!?”
One boy grabbed one of the toys from Karin’s bag: a powerful electric massager. He switched it on and it vibrated loudly even on the lowest setting.

“What the hell is this? Do you use this to get off?”
“How do you have this much SM stuff but no whip?”
Karin didn’t have a whip because she would order Rena to transform and bring out her Rose Baton, but the boys had no way of knowing that. The boys readied two of the massagers Karin had modified to be extra powerful and pressed them against the sisters’ crotches.

“Ohhhhhhhhhhhhhhhhhhhhh!! My juices are leaking! Th-the massager, ahhhhhhh! I-it’s too powerfullllllllll!!”

“Eeeeeeeeeeeeeek!! I-I can’t handle this massager! I-it’s only meant for Onee-chan! Ah, ah, ahhhhhhhhhhhhhhhhhh!!”

The vibration pierced their entire body and they moaned with no hint of shame. The increased level of stimulation finally brought them to climax. When the massager touched them, the clip barely hanging onto their clit popped off. The mix of pain and pleasure that caused made the previous pleasure seem like child’s play in comparison. Then the boys switched the massagers up to the highest setting. Their minds and visions went blank, all their other senses were blown away, and only the ecstasy remained.

Their hair flew through the air as they convulsed like malfunctioning automatons and squirted love juices. Their eyes were rolling back in their heads, their melted expressions changing to ugly orgasm faces.

The heroic spirit that had supported them so far had finally succumbed to the pleasure.

(I-I can’t do it! I can’t resist!!)

(I-it’s too much! Ahhh! I’m going to lose!!)

The sisters were so in sync the word “defeat” appeared in their minds simultaneously here. A moment later, they had collapsed forwards, caught each other in their arms, and started making out.

“Karin, Karin!!”

“Onee-chan!!”

They called each other’s names while more semen filled them. This time, they accepted the pleasure.

The instant they succumbed, their strength returned to them. They now had complete control over their pussies and they used that to pleasure the cocks inside them.

“Whoa! Th-that’s so fucking good!”

“Ha ha ha! Look at them! They’ve completely given in!!”

The boys’ laughter stabbed into their hearts. They were stricken by humiliation and defeat. But the snowball had already started rolling down the hill and they couldn’t stop it now.

“Not inside me! Not inside me! No, no, no!!” Rena shouted like a child.

“You won’t get away with this! You…you…ahhh! Cock, coooock!!”

Karin’s expression and moans said something very different from her words.

“I don’t care what you say when you’re squeezing me like this!!”

“I’ll fill your womb!!”

The boys standing around them jerked off and took aim at the pleasure-crazed girls. The sisters now held the massagers and pressed them against each other’s pussy.

“Ohhhhhh! I’m cumming, I’m cumming!!”

That shout signaled the end of the tragic and obscene gangrape. Rena and Karin both pressed the sex toy in their hand hard against the other’s clitoris. The clips flew from their nipples and they arched their backs.

“D-don’t cum inside meeeee! I’m cumming!! I’m cummiiiiiiiiiing!!”

“Please not inside me! I’m cumming! No, your sperm is filling my womb! I’m going to get pregnaaaaaaaant!!”

The heroines’ cries echoed across the pool. The males’ hips thrusted up into them, pounding their cocks deep inside.

“I’m cumming!!” one shouted.

Then all of the male cannons fired.

Smelly cum stained the heroines’ sensitive bodies inside and outside. A milky shower poured down on the girls and their see-through uniforms, soaking into their beautiful hair, thighs, and even feet. The torrent of semen released inside them joined all of the cum already in there and erupted back out to whiten the puddle on the ground.

“I-inside me! You’re cumming inside meeee!!” “Yes, i-it feels so good!!”

Rena and Karin tilted their heads back. And…

“I-I’m cummiiiiiiiiiiiiiiiiiiiiiiiiing!!”
Their humiliating orgasmic defeat arrived at the exact same moment. Their tongues stuck out and their eyes rolled back in their head for ugly orgasm faces that left no sign of their usual good looks. The boys couldn’t stop ejaculating when they saw that.

“I’m cumming!! Your cock is so good!! Creampie orgasms are the best!!”

“Onee-chaaaaan!! It feels so good! I-I’m going to lose! It’s too good! I’m going to turn into a sex slave!!”

They had both fully succumbed to the pleasure. The sun was setting, but they were trapped in this cage of pleasure until the boys were fully satisfied.

 

“Ahhn…hhh…ah, ahhh.”

“No more…water.”

Night had almost fully fallen and the sound of spraying water and weak female voices could be heard from the pool.

The sisters were being hosed off after being left so thoroughly covered in cum. Their shirts were pulled up past their breasts and their skirts had been stripped off and left balled up on the ground. The boys were teasing the half-naked sisters with the hoses again in the name of washing them off.

“Ah, ah…ahhhh.”

“Ahhhh…I-I’m cumming…I’m cumming.”

The exhausted girls didn’t even have the strength left to raise their voices. But their orgasming bodies still trembled and love juices still squirted from their pussies.

“That’s enough for today. See you tomorrow.”

The boys emphasized the word “tomorrow” and left the pool with crude sneers and mocking laugher. Left behind, Rena and Karin were too weak from the many orgasms to move. The semen had been washed off, but there was no getting rid of the cum smell clinging to every part of them. They breathed through that lingering male scent as they gradually recovered.

“Karin, are you okay?”

The first to get up was Rena. She helped Karin up, collected her skirt, and put it on. Karin weakly stood up, grabbed her skirt, and put it on as well.

They had tears on their cheeks. They had trained so hard so they could fight and protect earth and its people, but now fellow humans – their friends even – had raped them.

Karin silently gathered up the toys and Rena placed an arm around her beloved sister’s shoulders.

“Karin, this is part of our training. No, it’s part of the fight.”

“I know,” replied Karin.

When she turned to face her sister, her face was a mess of tears, sorrow, humiliation, and shame, but she still managed to smile.

They glowed with a red and a blue light. They consumed a large quantity of Altair Energy to eliminate their exhaustion and the semen. That also eliminated the risk of pregnancy.

“We’re stronger now.” Rena touched her skin where so much semen had covered her earlier and put on a fragile smile of her own.

While they hadn’t been transformed, it was still devastating to know that these human men – no, boys – had overpowered them like that.

“Yes, this is nothing to me. I was prepared for this from the moment I became Altair Marine.”

Karin was still smiling, but the rest of her expression crumbled. Her lips were stiff and her shoulders shaking. Rena looked up at the stars starting to appear in the sky, blinked several times, and pulled Karin close.

“Let’s head home,” whispered Karin.

The two of them left the pool. They vanished into thin air in the deserted schoolyard. A faint red and blue mist floated where they had disappeared.

Night had arrived and the heroine sisters would be out in the city soon enough. Their spirits would not be broken.

 

“Get ready,” commanded Velka in the Hypnos hideout.

The Hypnos had been watching what happened to the two heroines at the pool.

A great quantity of data was projected into the air. It was all concerning Rose and Marine’s status: their mental state, the progress of their hypnotic suggestions, their degree of arousal, the sensitivity of their various erogenous zones, the strength of their costumes, their physical condition before and after transformation, and their remaining energy.

They had transformed countless times and repaired, reconstructed, or cleansed their torn, stripped off, and stolen costumes. They had trained without rest, restored their strength so they didn’t need to sleep, and purified their defiled bodies. They had been consuming their energy nonstop without any chance to let it recover, so while their supply of Altair Energy seemed bottomless, it was close to running out.

“In…yes, in another few days, this should affect their transformation itself. That is when we strike.”

Velka kept her eyes on the data. Everything was progressing exactly as the Hypnos had hoped – and exactly the opposite of what the Altair Guardians would want. They were so sensitive that any touch was enough to feel pleasure, their costumes were weak enough that even the grunts could tear them with ease, and they could barely fight at all. When they transformed, it switched on their pleasure. Just shouting their transformation phrase greatly increased their body temperature and heartrate and wet their pussies with anticipation. They were convinced they were growing stronger, but they were actually in dire straits both mentally and physically. Just one good push and they would become Hypnos sex slaves. No matter how pure and noble their minds, their bodies would fall.

This would be over in just a few more days. Velka laughed in unrestrained delight.

The live footage of the sisters showed the Altair Guardians out in the city being insulted and fucked by the city’s men. In the city, it was rumored the Altair Guardians were actually horny sluts who went around sleeping with random men every night. The rumor was believed more by the day, so the Altair Guardians were no longer cheered by the people even when they made an appearance during the day.

Velka ran her fingers along her crotch and poured her sadistic gaze into the footage.

The zombie-like crowd gathered around the two heroines numbered more than a hundred tonight.
