The Giantess Effect (Patreon)

“They’re controlling you!” the words of Admiral Anderson shook the Illusive Man to his core. “You’re indoctrinated,” Anderson added, looking down at his hands the Illusive man could see the blue glow of circuitry running down his hands and up his arms. How far had he let this go? Was he even really human anymore? He was willing to make any sacrifice to remove the Reaper menace. To destroy them completely. When had he started thinking about controlling them?

“You’re failing humanity now,” Sheppard grunted at the Illusive Man. Those words struck him in the chest. Had he? After all this time and sacrifice had the Illusive man actually failed humanity. The identity he had built for himself was it all for nothing? After giving up his old life, sacrificing everything to truly become The Illusive Man, a protector of humanity, had he truly failed them, was he nothing more than just Jack Harper? Just another man to succumb to the Reaper menace.

Jack looked back and forth between Sheppard and Anderson “I... they’re too strong Sheppard, but I’m not going down without a fight.” Calling up his Omni tool The Illusive Man brought up his last ace in the hole “I’m betting it all on humanity Sheppard.” Jack tapped on his Omni tool screen and activated project M. It was something he never thought he would need to use, but he had lost this battle, the Reapers had him. He wasn’t going to let them win the war. “Goodbye Sheppard,” The Illusive Man said he put the pistol to his temple and pulled the trigger.

Sheppard looked down at the corps of The Illusive Man. Project M activated flashed on the dead man’s Omni tool “what did you do Illusive Man?” Sheppard asked before clutching a blood-soaked side and falling down alongside the also wounded Anderson.

Back on Earth, the war waged on the culmination of all of the Milky Way's militaristic forces pushing back against an enemy that was hell-bent on their total destruction. Miranda Lawson gritted her teeth as she applied some Omni gel to one of her wounds. Watching the flesh stitch itself back together, she charged another biotic blast. As she was about to jump out from behind cover a cold shiver ran down her spine.

She gasped and the biotic energy faded away, a warmth spread from her chest seeping out into the rest of her body. “Miranda are you okay?” The Quarian, Tali said as she fell in alongside Miranda. Tali generated multiple sentry drones to cover them.

Liara put her back to the cover on the other side of Miranda she threw up barriers around the three of them “this isn’t going well,” she said looking at the other two women “whatever Sheppard is doing up there, it better be done quick.” All three looked up at the pillar of light that Sheppard had walked into.

“Miranda,” The Illusive Man’s voice cut in over the Cerberus commanders’ com “if you’re hearing this, I’m dead.” To Miranda’s credit even given what she knew of the Illusive Man she still felt sad. “That means I’ve activated project M, you’re no doubt feeling the effects now,” Miranda shuddered as another shiver ran through her body. “I made it a point to invest in as many plans as I could to combat the Reapers, you are one of those plans,” Miranda groaned as her breasts lurched out swelling inside of her suit.

“What in the goddess?” Liara said as Miranda continued to swell out her ass grew plumper and fatter, her hips flaring wider and her thighs grew thicker. Then her whole body grew. Miranda’s arms and legs shot out, her torso grew, her shoulders stretched. Her suit seemed to stretch along with her.

Tali shifted back away from Miranda “bosh'tet, what is happening to you Miranda!” the small curvy Quarian said shocked.

Miranda looked down at the two of them now as she was several heads above them “I…. I’m not sure,” she said before letting out another groan. Whatever was happening, it certainly felt good.

The recording from The Illusive Man in her ear continued to play “I worked with your father to not only make you a genetically perfect human, but also a perfect bio match for the protein nanomachines we developed.” Miranda huffed and moaned as she grew out again, pushing taller, larger and curvier. She had a nicely toned ass before. Now it was gigantic and fat it stuck out from her narrow waist like a sore thumb. Her breasts went from what had been perky B cups to now massive orbs on her chest.

If she had been a normal size, she would have said they were like beach balls. In reality, though, now given how big she was, they were closer to the size of beds. “I hadn't planned on using you in the final battle as the biotic enhancements from the nanomachines came with some, shall we say, interesting physical changes,” Miranda scoffed and rolled her eyes at that statement.

As Miranda grew and soon grew, the cover she had taken shelter behind was no longer of any use. Her growing body was putting her in the direct line of enemy fire. As the reapers indoctrinated troops laid eyes on her, they immediately began to open fire on her. “No!” Miranda shouted as she put up her hand. A powerful barrier emitted from her and blocked all of the enemy fire. Along with pushing any of the indoctrinated troops away from the Alliance forces. Enemy forces that had been hit by the barrier were flung back with a force that destroyed them immediately.

Miranda looked in shock at her glowing blue hand. She had always been a powerful biotic, but nothing to this extent. “Tuho! That was incredible Miranda,” a now even smaller looking Tali called up from the ground.

Miranda stood now as she felt another tingle of warmth wash over her. She moaned with pleasure as the sensation became more and more erotic the bigger she grew. Miranda was now tall enough to stand over the allied trucks. “However desperate times call for desperate measures,” The Illusive and continued in her ear. She held her hand up, continuing to maintain the large barrier she had erected. On a normal day, Mirada could maintain a barrier large enough to protect four to five people for at most twenty minutes. Right now, her barrier covered a sixty-foot sphere and even with enemy fire pelting against it Miranda wasn’t straining herself at all.

When another growth spurt hit Miranda’s, barrier grew along with her. The bigger she grew, the greater the safe zone she was able to project. “I will not let humanity fall Miranda, you are the last defender of humanity now,” The Illusive Man’s voice cut off. Miranda gasped as a much larger growth spurt overwhelmed her. She lurched out taller and taller, she was half the height of the buildings around her now. Her massive breasts hung down past her belly button and were easily the size of houses. Her suit was stretched so tightly now it left nothing to the imagination.

Her large nipples jutted out as they grew hard. Each swell bigger provided Miranda with more and more pleasure. It was getting hard to concentrate on maintaining the barrier when she was on the verge of orgasming from her change in size. Her ass cheeks were now rubbing against the building behind her. Miranda was getting massive. If this kept up, she was going to be bigger than a Reaper. “This unnghhh is Mi-Miranda Lawson ha...have all Allied forces fall back to me,” she said over the coms “I have a barrier in position that will protect all inside of it.”

As Liara looked up between Miranda’s legs she blushed “Oh goodness, well, I guess that’s what a human vagina looks like,” Liara watched retreating troops look up at the spectacle that Miranda had become in awe. Some bashfully kept their eyes down. Some looked up with lust in their eyes. Though most were too tired and worn out from the fighting to care. They were just happy to have a moment of reprieve.

As Miranda grew larger and larger, she was able to look down over the city of London. The indoctrinated seemed to glow to her vision, making them easy to pick out. It was probably another change the nanomachines made. Raising a hand, thousands of the Reaper troops were launched into the air hundreds of feet. Launching out a singularity over the city, the Reaper army in London was sucked into the singularity and eradicated.

Satisfied the Alliance ground troops were safe. Miranda started walking towards one of the not so intimidating looking Reapers besieging her planet. With every step, her breasts bounced, and her ass jiggled. One of her hands went to her massive nipples and squeezed it tightly. She moaned in delight, everything on her felt like it was on fire. She was alive with pleasure, passion, and power. Blue biotic energy engulfed Miranda and she launched like a comet at the nearby Reaper. Slamming into it with a blast of energy, the Reaper shattered against her power.

Two more of the Reapers let out screeches of alarm to call in their brethren. Miranda used her enhanced ability to pull the large reaper in next to her. As the sentient AI being hurtled towards her, she slammed her fist down onto the Reaper smashing it into the ground. Metal crunched beneath her fist as Miranda punched clear through the Reaper.

More of the Reapers descended onto Earth flying towards the massive growing woman. Miranda continued to shoot out bigger and bigger. She was now looking down over the city. As Reapers flew towards her, she merely caught them out of the air and crushed them. As their lasers ripped across her body Miranda groaned lustfully. The lasers made short work of her clothes as Miranda’s white and black combat suit burned away, but the Reaper lasers only felt like nails being dragged across her sensitive skin. They left red marks but that was it, there was no effective damage being done.

Miranda’s body was growing so massive and powerful now there was nothing the Reapers could do to stop her. Miranda laughed in delight as dealing with the universe's most powerful foes became nothing more than a children's game to her. Bigger and bigger and bigger she grew until she was larger enough, she could look down at the planet itself. She was standing out in space now overlooking everything. Using her Biotic powers, she lifted herself away from the Earth so she wouldn’t do any harm to it.

Thousands of Reapers were closing in on Miranda now she just chuckled “I’ve finally become the perfect being now Reapers, you’re nothing to me.” With a flex of her hand, Miranda pulled all of the Reapers attacking Earth together into one pile. With a clap of her hands, she crushed them all, destroying the immediate Reaper threat to Earth. As she continued to grow and with the Earth no longer in peril Miranda couldn’t hold back anymore. She needed release, her hands made their way to her massive breasts, groping and fondling them. She gasped and moaned in pleasure as her nipples tantalized her.

Moving one of her hands down Miranda started to rub her pussy; it brought her to whole new heights of pleasure she never thought was possible. Rubbing her sex fiercely, she screamed in delight: "Ohhh yes! More! More! More! I want to be bigger!” she cried out as her hand flicked her bean like it was going out of style. It wasn’t enough though Miranda needed something filling, her stretching her. Looking around, her eyes landed on the citadel. Closed, it looked like the perfect instrument for her pleasure.

Reaching out, she grabbed the massive space station and pulled it towards her. Inside the space station, Commander Shepard and Admiral Anderson sat looking out the bay windows as they were pulled towards the massive horny giant that was Miranda. “It’s uh quite a view,” Anderson grunted.

“Heh best seats in the house,” Shepard replied as Miranda brought the citadel between her legs.

The End.
