The announcer crackled over the loudspeaker. “Today we will have an interesting matchup. These ladies are known for manipulating the world around them.
The first girl bounded out and spun around. Her blue dress twirled as she smiled, her bright blue eyes alight with wonder. She wore a faded white corset and a blue dress jacket. Her cleavage displayed beneath a large silvery collar showing an empty birdcage. Her dark brown hair cropped just below her ears. “This lovely lady has the ability to create tears: which open doorways to another universe. Fresh from confinement, this, of course, is Elizabeth from Bioshock: Infinite!” She looked around the arena with amazement.
The next contender strolled into the arena. Blue tattoos snaked beneath a torn pink shirt and tattered brown pants. Adorned with an exorbitant amount of leather, she walked with an air of confidence. Her bright amber eyes were only second to her pointed crimson hair. She blew an exaggerated kiss to the camera. “This fiery young lady is from Borderlands! This Siren is known as Lilith!”
She fired a few shots into the air. “Let’s start this thing already!”
“And finally we have a test subject from Aperture Science.” The final woman dropped onto the battleground. A white tank-top covered her modest top while an orange jumpsuit was tied around her waist, covering her lower half. Wearing her well-known Long Fall Boots, she inspected Elizabeth and Lilith with narrowed eyes. Her ponytail whipped as she faced forward again, ready for the match to begin. “The strong silent type: Chell!”
“Tonight’s gimmick: expansion! We have three color-coded pylons that will expand a different part of the body when a contender is within proximity; the amount varies depending on how close they get. There is an expansion free space in the center of the arena, but it’s quite small! Once a competitor is immobile then they lose. And now we’ll let the action begin!”
Lilith phaseshifted, vanishing immediately.
Chell created a portal at her feet and another on the side of the tower, using creative portal placement to continue ascending higher.
Elizabeth trotted innocently to the center of the arena.
Elizabeth was blown backwards as Lilith reappeared, setting off her Phase Blast ability. Elizabeth tumbled through the dirt, and into the blue post. She rose; wincing as her breasts grew visibly, pressing upward past the top of her corset. She opened a tear over the pylon, showing a time before it had been there. However, this tactic did nothing as her breasts pushed against the flexing corset. “Ugh, why won’t it stop?” The tear closed behind her as she ran desperately, clutching her chest, moving back to the center.
“The pylons are only markers. The expansion effect will happen no matter what happens to them. Look at those boobs begging to be free, Elizabeth!” The announcer chuckled. “Don’t deny them freedom!”
Lilith laughed as she watched; she was free of the pylon’s effects in the middle dead-zone. She had only received a small belly increase while she had phase-walked. She raised her hands and waited for the buxom girl in the blue dress to come within striking distance. “Do you like pain?” Lilith mocked.
Before she could strike, a portal appeared beneath Lilith and she fell. Disoriented, she realized mid-air that she had been launched across the arena. She smacked against the ground, rolling beside the red pylon. “Ow, what the hell?” Awareness struck her and she scrambled to her feet, sprinting away in a panic. Her enlarged belly caused her to stumble as she saw she had been running directly at the green pylon. She turned away and ran more cautiously toward the midpoint.
Elizabeth awkwardly tried to free herself from the corset, which was mashed beneath a small mountain of flesh, which now poured over the top. Lilith, on the other hand, had expanded freely after she had unzipped her jacket and tossed it aside. Her belly looked tight beneath her loose fitting shirt, as if she had swallowed a basketball. Her backside had also grown, bouncing more than it had before. Her pants had ripped farther to accommodate her larger hips. Her legs had grown proportionately, thickening to match her supple rump.
Lilith was relieved to see that she was no longer growing. The apple-assed girl with a taught belly drew her submachine gun and edged closer to the still struggling girl in the middle. Her eyes, however, were searching above for the other opponent.
Chell knelt atop one of the towers; she had used her portal gun to ascend out of reach. Lilith finally spotted her and started firing.
“Also, all of the weapons are loaded with rubber bullets.” The announcer chimed.
Chell created another portal, sending the girl to the blue pylon. Chell smirked as she watched the Siren’s breasts grow as she dashed back to the middle. Lilith vanished just before she reached the center.
Elizabeth still tried to free herself from her painfully tight top, ignoring the other two women. Abruptly, she launched forward, feeling the pressure release as she tumbled. She noticed the white corset lay in the dirt in front of her. Her enormous breasts now exposed. She stood slowly, holding her chest, feeling her belly growing due to her proximity to the red post. She labored to contain her mammaries, as they both spilled past her grasp.
She gave up and they sagged beside her growing belly. She couldn’t run; instead, she walked hurriedly away from the pillar. “Well, looks like our lovely Elizabeth breasts are the size of large watermelons! Look at them sway! How nice of Lilith to help her free those beasts. Lilith is now carrying 34H breasts as well – they look like two honeydew melons. And it looks like Chell is certainly the top dog for now.”
Chell shot a portal into the center of the arena, between the other competitors. She created another at her feet. Chell popped up between the other girls, landing spryly as she shot another portal to the dirt beside the yellow pylon. She aimed to shoot another portal beneath Lilith, but suddenly she was launched through the air. She lost her portal gun as she tumbled; standing again and feeling a pain in her side where it had hit her, she saw a motorized robot, which had two flags strapped to its back and a creepy, broken George Washington mask. It began cranking the handle on its gun.
Bullets flew around Chell, who ran along the edge of the arena. She grabbed her portal gun and made her way to the top of the tower again using calculated jumps. Elizabeth closed the tear and grinned at her from below. “Good luck being acrobatic now!” Elizabeth yelled.
Chell noticed her backside had swelled. Untying the orange jumpsuit that had been around her waist, she pulled it above her wider hips and tied it again. She watched below as she moved, getting a feel for her added girth.
“Can you make one of those tears to get me a sniper rifle?” Lilith asked as she shot into the sky with her SMG, missing Chell entirely.
“Sure thing.” Elizabeth mimed the action as she created a tear with a lone sniper rifle sitting on a desk. Lilith grabbed it and checked the magazine before aiming her shot. Before she could get a round off Chell made a portal below her, sending her to the blue pylon. The Siren immediately went invisible. Chell watched, waiting for her to reappear in the area. She was stunned when a bullet knocked her from her perch.
Lilith cheered from the middle, having used the portal to travel backwards while she was phase shifted. Her breasts had grown larger, stretching the tattoo that curved beneath her shirt, but she didn’t mind. She watched as Chell twisted to land on her feet at the last moment, absorbing the fall. Lilith shot her again, knocking her portal gun away and sending Chell flying into the wall. Chell stood, grasping her shoulder where she had been shot. She ran to her portal gun, but it was no longer there. Instead, there was now a scene of destruction behind a feudal samurai who promptly kicked her squarely in the stomach.
The tear vanished as she flew backwards. She hit the green pylon; Chell was in visible pain and unable to gather her bearings. Her butt expanded beneath her, moving her into a sitting position as it swelled along with her thighs, and to a lesser extent, her legs. Her jumpsuit untied and stretched until it finally tore. Unable to recover now, she huffed as she continued expanding disproportionately, leaving the rest of her body shaped normally. It didn’t take long until Chell was completely immobile, her enlarged posterior raising her four feet off of the ground.
“Oh my, looks like the tides have turned! Chell went from being on top to having a really large bottom!”
“Ha! Someone needs to sit and think about what a bad girl they are!” Lilith dropped her rifle and vanished again.
Elizabeth stepped backwards, unsure of where her assailant would strike. She opened a tear to a tesla coil, which arched nearby, ready to zap her enemy. Lilith appeared and blasted Elizabeth in the direction of the red pylon. Just as expected, the tesla coil charged and jolted Lilith, dropping her.
Elizabeth struggled to stand as her belly grew. She had gone past the red post, so she had to pass it to return to the center. She breathed deeply and charging ahead. Her steps were uneven as her breasts and belly rocked her from side to side. She was almost to the middle when she stepped on her dress, tearing it; she rolled like a ball, coming to a halt beside Lilith.
She tried to lift herself, but it was taxing, with her enormous breasts and ridiculously large tummy. She rolled onto her knees and somehow managed to lift herself. Her belly sagged between her legs and past her knees. She took calculated steps as she hefted her frame, showing that she certainly wasn’t immobile. Leaving her tattered dress behind; she was nude now, save for her dress jacket and necklace, which was hidden between her breasts.
Elizabeth started to wobble as she stood above her opponent. Lilith’s bright amber eyes opened just in time to see the expanded woman falling upon her. Elizabeth fell to her hands and knees, still holding the bulk of her weight as she came crashing down, straddling Lilith. Elizabeth’s loins landed directly on the Siren’s face.
Lilith immediately struggled, slapping the colossal woman’s thighs frantically and trying to slide from beneath the mountain of soft flesh upon her.
Elizabeth, however, loved her struggling. “Oh, my god! It’s amazing!” She moved her hips. “I’ve never felt this before. Don’t stop!” Elizabeth cried with delight as she reached climax. Lilith kept struggling, slowly sliding free. It took her a few more attempts, but she finally wriggled from beneath the recovering mound of Elizabeth.
Lilith was breathless, crawling toward the submachine gun she had dropped. She grasped it and rolled onto her back, taking aim at the girl’s ass.
Looking over her shoulder, Elizabeth opened another tear just in time. A large handed robot with a human head appeared, grabbing Lilith. He proceeded to rip her clothes away piece by piece before tossing her toward the blue pylon. She struck the wall; she laid there as her breasts grew to sit beside her. Exasperated, she called: “I’m done, it’s over!” Her breasts ballooned to look like beach balls before they reached their limit.
Then, a portal appeared in the wall beside Lilith’s head.
Dropping the portal gun, Elizabeth wiggled her backside through the opening just enough so she wouldn’t completely smother her opponent. “I liked that, you have to do that again.” She lowered her hips, moving them until she felt the wet prodding of Lilith’s tongue. “I’m not sure if you’re doing that on purpose or you’re trying to tell me to stop.” Elizabeth moaned as Lilith slapped her ass. “Oh, I am NOT going to stop.” Elizabeth bit her lip and gripped her inflating breast.
“It looks like Elizabeth is the winner!” The announcers laughed as she shifted her weight, leaning forward on her arms. Her eyes clenched; her massive breasts and swollen belly rested upon the ground as she moved her hips back and forth, allowing her victim the occasional breath. “Looks like her breasts are still growing through the portal, but I don’t think she really cares at this point.” Lilith jerked and grunted beneath the euphoric Elizabeth, struggling to be free. “I think we’ll leave them to their fun for a while.”
