The Earth Heist

By u/BigBourgeoisie

>What do you do when your monster girl invasion force encounters a world where every national leader is at each other’s throats and global annihilation is always an angry speech away? Simple, you take out their biggest gun. Better yet, steal their biggest gun.

>”Cave Bat One to Grease Monkey, timecheck?” The comms are clear as day. A shifting about of the observer’s hatch accompanies the Gremlin’s work.

>”Sun is rising over Vladivostok, falling over Reykjavík.” Her periscope stops moving and she gets back to navigating the vessel.

>”Right on time.” Cave Bat One, the Lilim in charge who’s true name was Venala, puts her hand on the door release.

>”500 meters to contact, 700 meters to weapons platform.” The driver, an Anubis, continues to observe distances.

>You look around at your fellow soldiers, 16 of you being present in total. They were from all walks of life, including Dhampirs, Weresheep, Akanames, and even a Slime.

>Cave Bat One looks back at your squad. “Remember your training! Keep it quiet, but await orders at a moment’s notice!” She pulls the door release.

>The cargo bay doors overhead open and reveal countless stars as well as the dark Earth illuminated by electric lights. Your propulsion unit propels you upwards alongside all of your comrades-in-arms. After getting above the spacecraft, you see the target.

>A giant, expansive space station painted as black as the void between the stars.

>Sure enough, the “biggest gun” was in sight. Dozens of small satellite weapon carriers were scattered around the station. The armament aboard each was 20 individual 40 meter long tungsten rods, a method of kinetic bombardment. The plan was to have the technicians aboard the other infiltrating spacecraft hijack and modify them to be used by us instead.

>That however, wasn’t your job. You and all those around you were elite anti-personnel infantry, meant to subdue the coincidentally all-male crew aboard. A job which was far more fun in your eyes.

>Your black claws typical of a fierce hellhound are surrounded by the padding of the space suit. They grip the motion controls by your legs that control your propulsion.

>Your movements generally follow those who were around you in coordination with the planned attack. You scatter from your comrades and move towards the station.

>”All units, double time it, our technicians can only jam their sensors for a few more seconds.” Cave Bat One’s voice was ordinarily sultry, but always maintained decorum around her soldiers. Mid-operation was NOT a good time to have fantasies.

>”100 meters to contact with the station, be ready to breach.” That was when the hatches of the station opened by surprise, and the armed astronauts flew out.

>”We’ve been spotted! Go loud, shields up!” Your claw that wasn’t handling your suit’s controls rises up and activates the defensive measure, a shield of titanium alloys which unfolds to protect your whole body.

>Bullets quietly whiz by, many bouncing off your shield as you and your squad continue advancing.

>Peeking over for a moment, you see that the soldiers are getting to be no more than 10 meters away. You increase your propulsion to its max force. “Beginning charge!”

>Your statement is acknowledged by your comrades, who charge at the same time to disrupt as many of them as possible. Your shield hits one of the astronauts, who becomes disoriented. You throw your shield aside and he raises his gun to fire at you again, whereupon you tear the gun from his hand and push him toward one of your squadmates.

>The Dark Priest who catches him swiftly moves to “neutralize” him. Amazingly, your fighting force outnumbers theirs and all of them fall to your assault.

>Cave Bat One propels over to you and motions toward a sealed, person-sized hatch. She was one of the few that didn’t already find a man. “Stand back.” You propel backwards as she creates a powerful fire rune with her dark pyromancy. Her hand stays open as she hides beside the hatch.

>Her hand closes into a fist. ”Breaching.” The hatch explodes and you swiftly move in with her. She propels towards and tackles a man who was standing beside the hatch as you quickly turn the corner. You see the gunner at the computer which controlled the firing system. He looks back at you and hurries to press the big red button on the screen that said “FIRE”.

>His hand was inches away from the interface when you grabbed his arm and hurled him against the wall. Of course, it wasn’t a strong enough impact to hurt him. You wouldn’t dare hurt him, because from the moment you came up to him, despite the absence of loose air, your mamono instincts allowed you to smell it on him. His energy was the one for you.

>After colliding into the wall, he reaches for a floating gun that was propelled around by the breach. You throw it aside and pin him to the wall while he continues to struggle. Thus you began “neutralization”.

>You do so in the standard way. There was a tube that connected his oxygen tank to his visor. You take the blade on your thigh and cut the tube near where it connected to his tank. For a moment, he has no way to breath and panics even more. You quickly take the tube and connect it to a port on your oxygen tank, and it seals itself in.

>Everything else will fall into place. You hold his arms down and press your visor against his. “Shhhhh.” You console him as the mana does its work. By connecting his visor to your air, the mana you give off naturally is being directly taken into his lungs.

>After a minute, his thrashing starts to subside until his arms no longer flail at you. After another minute, they wrap around you. You wrap your arms around him as well and your hand rests on the back of his helmet. Cuddling and breathing each other’s air is not nearly as efficient of an energy transfer as sex, but it would do for now. However, you have to make your intentions known. It was time for some precise speechcraft.

>”I assume by now you’ve taken enough note of my suit and my voice to know I am a woman, yes?” His voice is shaky, almost broken. “Y-yes…”

>You press a button on your suit to lower one of your internal visors, allowing him to see your face. ”Then please, lower your internal visor.” His hand shakes as it flips a switch on his suit, and it reveals his face under a thin layer of glass.

>He was young, his eyes showed off great ambition and a hidden tinge of youth, but in this state they only outwardly showed fear and desire. It was a face that you instantly fell in love with. His lips quiver in anticipation of whatever was to come next.

>You smile lasciviously at having such a fresh, tasty morsel at your disposal. You know you are meant to maintain professionalism, but you could have some fun, right? “Let me guess, you’ve only seen my face and you already want to ravish me, don’t you?”

>He averts your gaze and looks down. “...Yes…” You smile more earnestly this time. “Then I promise you, we can do it~” Your expression changes to one of concern. “But I need you to promise me that you won’t touch that interface again and you won’t hurt any of my friends who are working, okay?”

>He was putty in the palm of your hands. “A-absolutely, I w-won’t hurt them a bit.”

>You giggle and move him about so that his helmet is resting on your chest’s padding. “You’re quite cute, you know that?~” You don’t see his face at the moment, but you know it’s devil red. “T-thank you... I don’t get called that o-often…”

>There was plenty of time to relax with him, but you had just one bit of business to take care of. “Cave Bat One, this is Blaze Three. The crew has been subdued.” You look over to Cave Bat One, who is fondling the spaceman she tackled.

>”Affirmative, Blaze Three. Will relay to ground team and the technicians.” She flips a switch on her suit. “Jael One, this is Cave Bat One. Station is clear, proceed with the transformation.” She flips another switch. “Wolf Den, this is Cave Bat One. We’re almost done up here, begin your assault.”

>The comms come through to your helmet as well. “Affirmative, Cave Bat One. Our agents are going in. Safe hunting.” Your superior reciprocates. “Safe hunting.”

>Now everything was up to the others, and although you couldn’t do much in this suit, you had free reign to fondle your to-be husband.

>But it takes more than a space mission to calm a whole planet.

--------------------------------------------------------------------

>You have to admit, you were never that impressed with your order of the animal kingdom. You loved your people and your nation, but some of the mamono were really savages.

>Many of them were Hellhounds, Onis, Orcs, brutes of all kinds who were seemingly too stupid to even prepare an ambush or perform any kind of tactical strike.

>Some were more respectable. The Kunoichi, for example, were graceful assassins that could take care of even high ranking men. The Cupids also, as they were skilled with the bow from afar.

>But you knew you were the most skilled, the most patient of them all, and you were going to prove it in this military operation.

>Two weeks ago, you received your order to go through the portal and find a particular woman, with intent to monsterize her. Most mamono do this by using their bodies to please the human women, but you didn’t have that luxury. You were a highly intelligent amorphous cortex, a sleeper agent with devastating consequences. A parasite slime.

>Hiding yourself among suitcases and in the trunks of cars, you eventually made your way to the quiet home of your target, which was a modest house in a fairly small town. The whole way, you made certain not to jeopardize the mission and ensured not an ounce of your ooze was deposited on the ground.

>Rolling the blob of your body through the crevice of a window, you successfully infiltrated the house of the woman undetected. At the time, she was in the bathroom. You roll into her kitchen and look around.

>”Seems she’s been preparing something…” You see fruit scattered about and a blender. The opportunity could not be more perfect.

>Your body was like a cell, and as such had a cytoskeleton that produced movement. You stretch your body up and onto the counter. You then begin compressing it inward.

>At some point, you hear the door open down the hall. “Damnit, gotta finish up.” You compress your body previously made up of many gallons of fluid to no more than a single pint. You jump into the blender that was preparing the smoothie.

>She was none the wiser as you were taken into her body. “Humans are so unobservant of their surroundings.” You navigated through her systems and were present in nearly her whole being.

>You had the opportunity to take control of her whole body, to merge yourself with her at the sub-atomic level and create a whole new monster in the name of the Demon Lord. “But not yet...that will have to wait.”

>So you got taken along on her life. She went to the grocery store, she went jogging, she watched TV, she went to the movies with her friends and she helped elderly people in the town cross the street. To everyone else, she was just an ordinary person. Oh yeah, and she worked at the nuclear missile silo down the road.

>You tapped into her senses for the entirety of your stay in her. You got a very good look at the facility, you saw the entrances and the workers there as well as cameras and other intel good for an invasion. Every night, you took control of her body and sleep walked her to her computer in order to send intel to Wolf Den, the secret mamono base in the area.

>Of course, you also had to prepare her to be a worthy citizen of a demon realm. You focused on her endocrine and reproductive systems.

>In short, you made her horny as hell. Everyday when she woke up, she had to masturbate because of how great the urge was. As soon as she came home, she had to do it again because the pleasure irked her so greatly, and a quarter of the time she spent at home was spent pleasuring herself. Every night before bed she did it again and she kept waking up in the middle of the night to jam her fingers in her snatch.

>You kept pushing the boundaries of her hormones. She started having to masturbate at work during awkward bathroom breaks, and she came so much that it took ten minutes of preparation before she could leave the bathroom to get back to work. She kept biting her tongue so she wouldn’t moan like an animal in heat.

>While standing, she kept pushing against the edges of tables she could find so as to discreetly please herself. Of course, you kept vigilant watch, making sure she only did it when she wasn’t at risk of being found out.

>She started having to masturbate in the car to and from work, and getting home was barely more respite than she usually had at work. At least at home she could moan as loud as she wanted as she finger-fucked her drooling pussy. She no longer left her house except for work, and little that she did inside her house was outside the purpose of self-pleasure.

>At home, she moaned with ridiculous volume and her mouth hung open. She did not even need anything to watch or read, she just kept thinking of the idea of her getting savagely fucked by a mighty male. When night came, she had to go at least six rounds to calm down enough to fall asleep. She did not know why she did this, she just had to.

>Eventually, you tapped into her mind and she began to have troublesome thoughts. Things like “I’m too fucking horny. I have to stay home from work today.” and “I have to call someone to get groceries for me...I can’t go outside like this.” You couldn’t risk having others find out about her conditions, nor could you risk jeopardizing the mission.

>So for a while you eased up, instead compressing her arousal into several short intervals. However, those intervals were euphoric for her and they fulfilled the same task of developing her body for the Demon Realm.

>And that brought you to today, another completely normal day of work...except for the fact that this silo and every other one on the face of the planet was about to be disabled.

>”All agents, this is Wolf Den. Our girls in the sky are done. Get ready to begin the operation.” The HQ converses with you telepathically through faint radio waves. This is the day that Earth will become ready to be captured.

>Now that the second most dangerous weapon system, the kinetic orbital strike system, was in safe hands, it was time to neutralize all nuclear capabilities.

>It isn’t a day too late. You heard rumors around the base that the order for a nuclear strike was likely to come down from the top very soon, and sure enough, it did.

>The intercom came blaring in. “Attention all personnel. Prepare for launch in 45 minutes.”

>This woman wasn’t just any employee. She was the one who turned the key to authorize the launch.

>You were naturally a very calm individual, but you had to admit that this was getting you progressively more and more stressed. Much time passed and you did not receive any indication of the keyword that Wolf Den said they would send when the time was right.

>Five minutes before launch, you still didn’t hear anything. You strained your absolute hardest for radio waves, but nothing came through. Now she was before the console that would decide the fate of the world.

>”Begin final checklist.” The woman you inhabited took out her key, ready to insert it into the console. She looked across the silo to the booth where the other operator was, who was looking at her with the same serious tone.

>Your mind raced. Your terror increased, along with your willingness to go against orders and reverse the launch of your own will should the need arise.

>”Insert keys in 10, 9, 8, 7…” Your tendrils crawled over her whole brain, urgent to take control. “6, 5, 4…” Your slimy form was shaking. “Come on, Wolf Den, where is it?…” “3,2 KKZZZZzzzzzhh” The intercom halted the countdown and static came through, and then a female voice. “Hail, oh Queen.”

>There it is. Your form pounces, your tendrils inserting into her mind. Your form oozes out of her body and proceeds to utterly violate her. With the ounce of muscular strength you have stolen from her control, you make her throw the key across the room.

>She looks on in terror as your pink body suddenly annihilates her lower orifices. “What the hell...w-what are you?!” Another tentacle comes from your body and is shoved deep into her throat. “No more out of you...mumbling, short-sighted, weak human…You are about to ascend to the rank of citizen in our new kingdom…”

>Another tentacle emerges from your form and glances at the booth across the silo. As according to plan, a Vampire, whose form was almost indistinguishable from that of a human, was making swift work of the male operator.

>Just beyond your overwhelming joy of finally being able to take over this woman, you faintly heard radio waves from Wolf Den. “Stage 2! All warriors on the outside, begin your assault on the silo!”

>But now was not the time for dwelling on the duties of others. Now was the time for fusing with the woman in front of you.

>Your tentacles were ruthless in their assault on her body. Two of them squeezed and tickled her breasts, their wet forms gliding over her smooth skin. Another punished her small mouth, pushing in and out while collecting her saliva which was drooling out of her.

>Yet another was being inserted in and out of her delectable ass. Your influence on her for the past two weeks filled her with mamono energy and made her assets all the more appealing. She even began to experiment with fingering her anus, which made fucking it all the more easier. Her walls pushed back hard, but you pushed harder.

>Her pussy was the most palatable site of all. Your tentacle expanded to two inches in diameter and pushed in almost as far as to kiss the cervix. Even more interestingly, it was a two-pronged assault, as the part of your body that stayed in her tickled her most sensitive areas from within. The tentacle outside pushed in and out of her twice every second, making her even more pleased.

>On top of all of that, your rigorous training from camp made you a fountain of demon energy which made her interpret the pleasure as seven times greater than it actually was when her nerves transmitted the information. Her face was in pure ecstasy and tears of joy fell down her cheeks.

>The tentacle in her mouth vibrated as her throat attempted to put forth moans, but you increased her pleasure to the point where she couldn’t even think. She came rapidly, repeatedly, and hard, her juices making her a wet mess on the floor.

>Twenty minutes later, the female voice on the intercom came again, this time speaking slowly in the realization of triumph. “Attention all men and women holed up in this facility’s shelters and elsewhere in the halls. This is Lieutenant Colonel Victoriala Tectumen of the Demon Lord’s Second Special Forces Battalion. It is highly suggested that you surrender and come quietly. Any rifles, rockets and other weaponry you may have will have no effect on our defensive spells. So please, give yourself up to pleasure, and congratulations to all of you in advance on your new marriages~”

>A resounding cheer came through the halls because of the victory today, but doesn’t mean you’re done with the woman in front of you, as you continued to violate her for three hours. By the end of it, she really came around to it and was begging for more.

>At the conclusion of the session, a final tentacle emerges from your body that displayed your terrifying visage. It was unlike your target’s face in shape, size, width, height, length, color, and shared almost no similarities other than the presence of two components of the face.

>For your eyes looked upon hers and were simply two white beads like foam bubbles on the surface of a soapy bathtub, and your mouth was a long, white arc like a parenthesis. However, it would be your visage no longer as you took on the final step of assimilation.

>Your consciousness merged with hers, your minds becoming one and becoming a wholly new being. No longer were you Slime and Human, but Slime Carrier.

>Time passed, and slowly, painfully, the personnel came to surrender. Every man was given a mamono wife, and every woman was turned into a mamono, and they, as well as your invading force, received priority in capture of the surrounding towns.

>Very soon, you would also have one of your own, and that was going to be a moment to remember for the whole remainder of your existence.

>You faintly hear more radio waves in the distance. “Wolf Den to Cave Bat One, we have 60% of silos under control, we expect the rest to be captured in the next hour. How goes your campaign?”

>”Cave Bat One to Wolf Den, we are converting the weapons now. Expect launch within the next ninety minutes.”

>After all, a species reduced to firearms and bombs is easy to conquer with magic, but it’s even easier when they’re reduced to base instinct.

-----------------------------------------------------------------------------------

>”All mechanical units, the station is secure. Get to work.” The doors are opened, revealing a gigantic black sky littered with stars and the shining blue light of the Earth.

>Among the scattered distant lights were much closer satellites which presented your mission to you.

>Your propulsion unit sends you up and you begin moving towards the satellite. In the distance, you see the command station, which is now neutralized. You also see the mamono dressed up in their thick suits to protect them from the harsh environment of space.

>Yet, when you look down, you are not clad in any padding, nor did any visor conceal your countenance. Ceramic clothed you up and down, with a soft, silicone-like material providing you “tools” of your trade for acquiring men, appearing and functioning as close to flesh as possible.

>Your legs and arms are attached to you not by tendons and bony joints, but by gears and cogs. You are the steel and ceramic centurion of the queen, an Automaton.

>As such, you needed no suit to protect you because no part of you ever felt cold, nor did you need to breathe. This was the case with all the members of your squad, for you were the Mechanical Unit not only for your skills but for your appearances.

>You move towards the kinetic bombardment systems. Your mission was to convert their tungsten to demon silver, which would not only remove their ability to slaughter those below, but also make the humans fresh meat for when the portals open.

>However, the Demon Lord was wise, for she did not just propose to turn them to demon silver, but also to lace them at the molecular level with various crafted Demon Realm toxins, which would make it even easier to capture humanity.

>After a minute, you arrive at one of the weapon carriers, a cylinder carrying a round of 20 tungsten rods. You make contact and then move towards the tips of the sharp rods.

>You take out the toxin, which was an adhesive appliance, from your pack. Though your hands were ceramic, they easily spread it around. Much time passed as you worked.

>As you completed each one, you witnessed a point at which the rod was so covered in toxins that it seeped through the metal by itself like a fog rolling into a swamp. The whole rod would turn black and you knew that it was ready.

>When you had finished the eighth rod, you felt some rumbling beneath the platform, and you knew that it was movement. A side hatch opened and revealed a crew member who was armed, likely waiting for you to be off guard, but an Automaton cannot be caught off guard. He propelled out and began firing, whereupon you took cover behind one of the rods. He was careful not to waste bullets should you jump him while he was reloading.

>A very tense minute passed as you snuck peaks around the rod, followed by him firing at you, missing, and the bullets deflecting off the rod. You decided you should tell your comrades about this. “All friendlies, be advised. There is an additional crew member in the weapon system carriers. Likely battle engineers.”

>The armed man slowly crept towards you, his nerves demanding that he make a move. You already knew by instinct his distance from behind the rod. “1.6 meters...1.2....0.8” He stops propelling forward for a moment with his gun up and eases around the corner.

>However, you jump upon him, smacking the gun out of his hand and grabbing hold of his suit. “Hold fire, Human.” He swats around and tries to beat at you, but his hits break upon you like water on a rock. “Human, please halt fire.” Your words do not prevent his meaningless strikes.

>Communications opened up. “All units, we fire in 45 minutes, finish your jobs.” You decided you did not have the time to deal with this feeble human...although you had to admit, his breathing and pants were nice to listen to. “Hmm…, yes, you shall be my master, Human.” He stops swinging for a moment in confusion. “But understand, I cannot jeopardize the mission. I’ll be right back with you.”

>You take him to the hatch, and with your metallic hand, you grasp his visor and push hard, creating a dent in the visor with a hole devoid of glass. He started to panic at being exposed to space, but you threw him into the hatch and sealed it with your superhuman strength. You looked inside through the window and saw that he was no longer panicking, so he had oxygen, but he had no other visor in the small room to possibly come out with and try to strike you.

>You stay looking through the window for a moment, you imagine all of the things you were going to do with him. How you were going to let him take control and convince him to force himself on you, how you were going to turn the tide and force yourself on him, and all of the things in between.

>You imagine how he was going to walk you through the park and along the beach, how you were going to carry him and embarrass him in front of your comrades, how he would try to redeem himself by trying to pick you up, how he would tire from attempting to lift several hundred pounds of steel, ceramic and silicon.

>You imagine nights when you would watch the sun going down together and he would kiss you romantically, and then you would take it a step above and make passionate love with him. You imagine days when you both decide to stay in and let your senses drive you rather than logic, and you would fuck each other ruthlessly like animals in heat.

>You imagine going to a secluded place of nature with a waterfall where you would sit only in the presence of each other, in total peace. Most of all, you imagine all of the times he would say “I love you.” and your systems would be shaken up for a moment, and then you would return it with words and a “show of affection”.

>You snap out of your daydream and get back to work covering the remainder of the rods with haste. You would find a visor for your master later.

>You cover the remainder of the rods and inform the Lilim. “Cave Bat One, this is Jael 3, this platform’s converted. Requesting a Human helmet visor, my master’s one is broken.”

>”This is Cave Bat One, come to the main station.”

>You propel with eagerness which was unorthodox for an Automaton. Very soon, the master will come around.

----------------------------------------------------------------------

>You greet the Automaton and give her the helmet, whereupon she traverses away.

>You turn back to the man you captured, who is in your arms and holding onto you for dear life. His voice shakes. “P-promise me.”

>You put your hand on his visor. “Hmm?” His voice shakes again. “Promise me y-you won’t dispose of m-me when we get back down.”

>You put your visor against his. “I promise, I will never let you go or even try to hurt you.”

>He hugs slightly tighter around your suit, which conceals your elite body of a Lilim underneath.

>”Cave Bat One, this is Jael One. All weapons systems have been converted. Begin strike.”

>”Roger that, Jael One.”

>You move over to the weapon console down the hall, passing by the Hellhound who was groping her man through his suit. You carry your man against your chest, and he holds on like a needy child.

>You pat his helmet softly and take a seat at the console, allowing him to sit on your lap.

>You navigate through the console to the fire control system and select all the satellites available. You select multiple cities to hit with the strikes which would make them ready to be subdued by your forces, as well as several military bases and aircraft carriers.

>After all the access keys and passwords which the man in your lap was more than willing to provide, you come to the screen that says “FIRE”.

>With the push of a button, demon silver would rain from the heavens and coat the people down below. Yet, no harm would come to civilians from shock as demon silver was much weaker than tungsten, causing the metal shatter as it hit the ground and fill the area with clouds of it rather than breaking the ground.

>Toxins would spread throughout, making the people burn with passion, whereupon the portals would open and the men and women would be subdued. Seven billion people would be added to the Demon Lord’s empire.
