Super Smash Sisters

"GAHHH!" Zelda shrieked as she took a direct hit from a rocket propelled missile. The explosion sent her back a few dozen yards, far off the Kongo Jungle stage. Now at 124% damage, another well placed attack would easily prove lethal.

Zelda focused and changed her direction in mid-air back towards the stage. Samus, expecting this, walked towards the edge of the stage, preparing to prevent whatever strategy Zelda had to get back on the platform.

Zelda continued to drop, wanting to get out of the line of sight of Samus's numerous projectile weapons. Samus fired a few heat-sinking missiles, but they were too slow to change course in time to catch up with her. Zelda waited until she was directly below the ledge of the stage to make her move.

Samus smirked, already knowing the next action of her opponent. Zelda began to spin and emit a green magical trail with her hands and feet. After another rotation, she disappeared leaving nothing behind but a bright light and a series of sparkles.

Samus remained unphased by this sudden disappearance, as she had seen it many times before. She then leaped off the edge, positioning herself right above it, and lifted her heavy arm-canon into the air. She waited for a moment and then started to swing down the canon with all of her strength towards what appeared to just be nothing.

Suddenly, a hint of green light started to appear, quickly growing in brightness as a female form started to take shape. Zelda reappeared right underneath Samus just in time to be met with a powerful blow as Samus's arm-canon made direct contact. The massive impact combined with Zelda's high damage percent sent her plummeting down into the blast zone as her first stock of the game was taken.

Both Samus and Zelda now had 1 stock left each. With Samus at 38%, it was still anyone's game. Suddenly an item crate appeared. With Zelda still respawning, Samus quickly hurried over and punched it open. The crate broke open, revealing its contents to the competitors.

The items dropped were strange, Samus and Zelda both only recognized one of them. That item being a beam-sword, a sword with a metallic hilt and a blade of glowing energy. The other 2 items were mysterious vials filled with a pink liquid.

Samus looked at the nearest vial, it must be a buff of some kind. Maybe it would lower her damage percent or give her some kind of invincibility effect. She quickly grabbed it and drank its contents. Nothing happened. Quickly she decided to grab the other vial, perhaps its effects would be more helpful.

Meanwhile, Zelda decided to stick with what she knew. Now spawned, she dropped down and reached for the beam sword. She turned on the blade and struck Samus while she was distracted with the strange new item. The attack sent Samus flying back, allowing Zelda to claim the other vial for herself. She quickly downed it and waited for something to happen...but nothing did, just like with Samus.

Samus grunted as she hit the ground. She got up to her feet, but the task was more difficult than she remembered. She felt heavy, like she had turned into metal. That was another powerup in the game, but she looked down at her hands/canon and saw that she wasn't metallic at all. On top of that, she felt more constrained than ever in the armor, especially around the chest. What had happened?

Suddenly a loud "Eeeeeeeyah!" brought Samus's attention back to the battle as Zelda conjured up a ball of Din's Fire and sent it hurly towards Samus. She leaped up in the air to dodge it, but found she couldn't jump as high as she used to.

Zelda smiled to herself as the attack landed, sending Zelda flying backwards. However, she didn't fly back as far as an attack like that should have sent her either. Samus struggled to get up, her armor was cracked around the chest, which was strange because the fire had hit her in the leg.

Suddenly, both chest plates shattered as Samus's now huge boobs exploded out of her armor. Samus looked relieved, but the feeling only lasted for a moment as her face went back to expressing discomfort.

"What on earth is happening to my body?" Samus thought to herself. She struggled to stand back up, it felt like her power suit was shrinking around her. She had to get out of it. Samus grunted and leaped into the air the best she could and began to shed her armor. As she landed back on the ground, Zelda gasped.

Samus looked like she had gained at least 50 pounds, most of it going directly to her already sizeable bust. She examined her own body, but as her hands moved up and down her previously slim and solid figure, she noticed that she had put on weight in numerous places. Her once toned abs were now squishy softness as her pudgy belly pressed hard against the fabric of her Zero Suit. Her butt was a little bigger than it used to be, but the biggest change, of course, was the massive globes on her chest that blocked her view of the rest of her body. While she couldn't see her own face, Zelda could, and noticed it grew quite pudgier as well. A prominent double-chin was also present on her face, even when Samus looked back up.

Samus started settle down from the initial shock and began to evaluate the situation. She still had the same amount of stocks as Zelda, and was at a not-ideal 56 damage percentage. Samus did a double take. The stat by her name no longer said "56%", but instead said "56lbs." Did that vial cause her to gain weight?

Samus was interrupted from her thoughts as she realized another fireball was headed her way. She flinched as it struct her dead on. She hardly moved back at all that time. Glancing at her stats, it now read 65lbs. At the same time, she felt her body (mostly her boobs) expand ever so slightly.

Now Samus understood. The vial hadn't given her just a nerf or a buff, but both! The downside was that damage was now being transformed into raw weight gain whenever she was hurt in battle, but on the bright side, the added weight made it harder and harder for her opponent to knock her off stage.

With her feet planted, Samus began to charge her proton pistol. A powerful orb of energy began to grow at the tip of her pistol. Zelda, seeing this attack coming, began to jump out of the line of fire.

With the shot now fully charged, Samus fired off a shot at Zelda, who was able to easily dodge it with her agility. But Samus decided it was time to level the playing field, she fired another shot towards Zelda, higher than the other. This forced her to start jumping downward to dodge it. With Zelda right where Samus wanted her, she struck Zelda with her series of strikes from her plasma whip, which dealt a hefty 44% damage in total.

Samus glanced at Zelda's stats and noticed that the "%" symbol next to her name had been replaced with "lbs". As Zelda landed on the ground from the blow, she realized that not only did she not fly back as far as she should have, but the impact also hurt a lot less than what she was expecting. As she stood up and brushed herself off, she realized why. Her ass had definitely been given some more cushion, thus softening her landing. She grabbed it with both of her hands. It was enormous! It felt so soft and pillow-like under her now too small dress that was beginning to ride up.

Noticing Samus coming at her with another whip attack, she quickly jumped out of the way, clearly struggling to do so. Once she landed, she felt her gigantic ass violently jiggle behind her from the impact. This battle was going to get a whole lot tougher.

They both continued to trade blows, and in return, gain weight. Samus's boobs were starting to get so enormous that they were testing the limits of her high-tech Zero Suit. Every time she moved, her huge boobs were sent into a fit of jiggling and sloshing. After once particular hard landing, her boobs' inertia ripped straight through the nearly invincible fabric. The material was engineered to take damage from lasers, explosions, and all manner of abuse, but the mass of her approximately M cup tits were just too much. Samus took a deep breath with a nearly orgasmic moan as her naked breasts were now free from their tiny prison, letting her breathe much easier.

However, her chest wasn't the only thing growing. Now at 115lbs of gain, her belly now had a prominent series of rolls and her belly button was clearly visible pushing against the still-struggling Zero Suit. Her face was much pudgier now with her chubby cheeks helping her lips to form a scowl towards Zelda. Her ass had also taken its fair share of growth, but it was nowhere near Zelda's level.

Zelda's ass had become so enormous that it formed a shelf several inches behind her. Her dress had now fully ridden up all the way to the top of her booty shelf, putting the majority of her ass cheeks on full display for any spectators to see. Her belly also grew to a respectable size along with her flabby arms.

The two growing women ran towards each other. Well maybe "ran" is too generous of a word. But they briskly lumbered as fast as they could! Zelda tried to throw a punch, but her heavy arms made the attack very easy to dodge, even with Samus' hindered movement. Samus would normally use her whip to grapple Zelda, but with her added weight, she just didn't have the agility to flick her wrist like she used to. Instead she decided to just use her hands to grab her large target.

Instead of flicking her to the ground, like she would with her whip. She had another idea. She slammed Zelda down and pinned her to the ground with both hands. Then loomed her massive, naked breasts over her head and brought them down on her face as hard as she could. The great weight and size of her boobs sealed off all means of breathing in the process. Even wit her breasts resting on top of her face, there was still so much titty, that they overflowed around her head and onto the ground.

Zelda squirmed and struggled underneath the weight of Samus's breasts but it was no use. As Zelda suffocated, pulses of damage/weight flowed through her body with every attempted breath she took. Eventually, Samus completed the down-throw and Zelda was released.

Zelda stood up, taking a moment to compose herself. Samus looked her up and down. Her ass was absolutely gigantic. It was so obvious, that Samus could tell even though Zelda was facing her. Her thighs had turned into 2 gigantic pale pillars of fat and cellulite. They continued to flare outwards into her wide wide wide WIDE hips in order to support her titanic booty. A rip had formed in the top of her dress to accommodate her growing belly. Zelda decided enough was enough and just tore the rest of her clothes off. She needed to be able to move without being constrained by her clothing and besides, the only person who would see was Samus, another woman.

Samus decided to just let her body continue to rip her suit where it needed to. With how long this last stock was lasting, she accepted that both of them would probably be completely naked by the end of it.

Samus attempted to do a backflip out of instinct to reposition herself. But her new higher center of mass caused her to just flop into the air and  land hard on her back. Her gigantic boobs flopped over onto her face, completely blocking her vision. Zelda took this opportunity to slowly heave herself up onto the nearest platform. The wooden boards of the Kongo Jungle stage platform creaked loudly with each step she took towards the opposite edge.

Samus pushed enough boobage out of her face to finally see and looked up at Zelda positioned at the edge of the platform like a diver about to leap into a pool of water. Zelda did just that as her extreme-pear shaped body began to plummet down towards Samus.

Samus's eyes widened as a shadow began to grow around her head. Zelda's ass was quickly gaining speed, but Samus was just too fat and top-heavy to get up in time. Weighing around 125lbs originally and now with an added 256lbs of damage, Samus was demolished with nearly 400lbs of jiggling ass fat. The blow destroyed several of the wooden planks that made up the floor of the stage, and caused several cracks to form around in the boards around the point of impact. The destruction caused both Samus and Zelda to start falling through the floor of the stage.

While Samus fell out completely, only Zelda's ass had gone through the newly created hole. Using her belly as sort of an anchor, a firm grip on the remains of one of the still-attached planks, and a bit of levitation magic, Zelda was able to pull herself up to safety.

Samus began to panic. Zelda's fat ass had added another 150lbs of weight in just a single hit. She felt her body expand and accelerate downward. Her boobs grew so large in volume that they started to lift up like 2 jiggling parachutes.

She needed to get back onto the stage. Her jetboots weren't designed to carry anywhere near this much weight. She accepted that there was no recovering from this one. Then she remembered the barrel that floated underneath the stage! It was coming right for her! She still had a chance. She was falling too quickly to reach it though. She fired off her jet boots in hopes that it would at least slow her down enough to intersect the barrel. It was her lucky day, it did!

She landed inside of the barrel, err... almost inside of it. Her boobs had grown too wide fit through the opening and overflowed along the sides of it. Her growing belly now stuffed the barrel to capacity like a cork in a bottle. It would have to do. The barrel rumbled and shook as it began to fire. It blasted her up into the air, nowhere near as high as it normally would, but enough to make it back to the stage.

Zelda watched as the hyper-busty space pirate flew back onto the stage and landed right at the edge of the new hole she had created in the floor. Samus quickly tried to get back up to continue fighting, but she just couldn't stand up. Her body was much too fat and her boobs were wayyyyyy to heavy to lift. Zelda, still standing, saw her opportunity and took it.

Zelda waddled over to Samus, cracks formed in the wooden planks with every step she took. She placed a hand on each of her colossal ass cheeks and did her best to spread them apart as far as she could. It was difficult to get a grip on so much flab, let alone lift it up. Then she sat down as hard as she could on Samus's face, completely engulfing her in ass fat. Samus tried to punch and kick back, but Zelda could barely feel her under all of that ass mass.

Samus started taking on damage like crazy. Zelda watched as she quickly climbed from the 200's to the 300's to the 400lbs mark. As Samus's body grew fatter and fatter, Zelda felt her own obese body start to lift up.

Suddenly the stage floor started to creak and crack loudly. The boards around the two gaining goddesses started to buckle and strain. With a series of incredibly loud *SNAPS*, the entire wooden floor fell to pieces, shattering like glass and sending both competitors falling to their doom. With the floating barrel nowhere in sight, the two fighting fatties plummeted into the abyss below.

"DRAW!" shouted the announcer.
