When we last left our protagonist, Rikki, he was evading a rather annoying sister to two young sisters in order to keep from being infected with an old virus turned outbreaking virus called the Anthro Fat Virus, the AF Virus for short. What the virus does exactly is change in infected person into a very fat anthro female of him or her self. When it was first developed, it used to only be able to spread only by touch, but since Rikki has accidentally sneezed onto the ancient virus sample, it has now gained the ability to be spread airborne too. Why being changed into a female was 100% certain for males who had the virus was unexplainable.
About the whole city has been infected by this virus, leaving Rikki as the sole survivor in the whole city. He had locked himself in his room for the past few hours since the virus started effecting everyone. He wonders how everything is going out there now. He had put a breathing mask on since the virus first broke out so he wouldn't be infected by the airborne strain of the virus, although he was still susceptible to the strain controlled by touch.
As Rikki slowly opened his door, he looked to see that no one was there. He looked at his door to find a note.
"Dear Rikki, we're currently out to have lunch...and dinner. We'll be back in a few hours...depending on if we don't still get hungry then. If you need us, we'll be at the local diner. Signed, your family." The note said. Rikki sighed in response.
"Even my family's been infected...and it seems that virus also causes extreme hunger or an irresistability to food. I have to get back to Vanessa and Taressa's house and help them come up with a cure! But to do that..." Rikki looked out his window. "I'd have to go through the whole city. Without being touched once. By anyone." He breathed, then slowly went out of his home. The first thing he did was look around for Lena. She's the one who caused the outbreak to start, and she didn't even care.
"Phew, thank god. No sign of Lena...after we get the cure, if Vanessa and Taressa wanna spank her, I'll gladly join them." Rikki said to himself as he carefully walked through the city, there being no one there since everyone must be at the diners, restaurants, and fast food places, chowing down on food. He smiled as he kept walking, then tripped on something and started going out of control. He ended up breaking through a meat stand (that no one was at for some reason) and ended up being covered in sausage links. He also fell into a vat full of chicken fat and was covered in the smell of chicken.
"Ewwwww! Man, now I'm gonna stink up the whole place smelling like chicken!" Rikki said then realized something. "Wait...I'm covered in food, and I smell like food, and everyone's....OH F**K NO!" Rikki heard a big stampede start to come to him. He looks to see that practically every fat anthro woman is coming for Rikki. He screamed as he thought fast and went to a narrow alley and climbed up it, propping his body up to it and lifting himself up.
"Phew...that was close." Then Rikki heard the door to the rooftop open and more fatties ran out of there. Rikki went into his inner parkour as he ended up flipping and jumped over and around entire buildings in the city, and he didn't even know how he could do. The motions just...came to him.
He ended up evading them long enough to get back to Vanessa and Taressa's house, especially since he tossed back the sausages for the fatties to eat up to stall them. He busted through the door, yelling out Vanessa and Taressa's name. "Vanessa?! Taressa?! You there, girls?!"
"...Rikki? Oh, you came to help us? Great!" The obese bear and roo women said.
"Grounded and sent to her room with every privilage she had temporarily taken away." Taressa answered.
"Good...I put on gloves so I think that should keep me safe if I touch you." Rikki said, showing that he was in fact wearing latex gloves.
"Great idea, Rikki!" Vanessa nodded.
"So...how can I help you two out?" Rikki asked.
"We need you to keep us from eating, since we'll be so distracted from it that we'll never get this antidote done..." Taressa explained.
"So you have to keep any food away from us, and unfortunately we kind of ordered tons of pizza...just make sure we don't smell the pizza at least..." Vanessa continued, blushing...
"Well I obviously can't eat all of the pizza myself, what should I do with it? I''m obviously not gonna put it to waste, y'know." Rikki said.
"Hee hee, with talk like that maybe you should be a fatty like everyone else!" A very scary familiar voice was heard behind them...
Vanessa and Taressa were speechless with surprise, and Rikki was shivering from his shoes.
"Oh god....oh please god, don't let it be--" Rikki got interrupted by a big hug from behind from a familiar fat raccoon...
"Hi again Rikki! You're always so nice to hug!" Lena yelled with cheer. Rikki on the other hand was trying to struggle out of her beastly grip as he was already feeling the fatness getting to him, and Lena noticed and hugged him tighter.
"Get...OFFA ME!!!" Rikki yelled already feeling the virus getting to him already. Vanessa sprang to action...literally. She bounced in front of Lena (while almost bumping her head on the ceiling in the process) and pulled Rikki out of her grasps.
"LENA! WHAT ARE YOU DOING OUT OF YOUR ROOM, DIDN'T I GROUND YOU?!" Taressa roared with anger as Vanessa grabbed Rikki and pulled him out from Lena's hands.
"Awww, the door rang and I had to answer it, then after that I got something that we'll all enjoy!" Lena said, carefree as always. Rikki waved his arms and Vanessa jumped (and almost hit her head again) at seeing Rikki getting smothered and suffocating from being squashed against her large bosom. She immediately pulled him out and he took a deep breath.
"Oh god! Almost passed out....but I don't feel too good..." Rikki said as he already started to look much fatter. His belly got poked by Vanessa with a worried look in her eyes.
"Oh no, you're infected with the AF Virus now!" Vanessa yelled as all of the hair on his skin started to grow out all over his body.
"What?! You mean I'm gonna be a fatty anthro now?!" Rikki yelled, having answered his own question as he saw the black fur he was growing and the big belly that was growing larger and fatter by the second.
"We have to get this antidote made now!" Taressa yelled.
"Awwwww, but I haven't given you all the thing I thought you'd all enjoy...PIZZA!!!" Lena giggled, holding out several boxes of pizzas.
Immediately everyone else stopped in their tracks and in a matter of seconds, everyone was eating pizza together. As Rikki ate, he continued to grow fatter, and was looking a lot more feminine as well. His hips grew out to accommodate the fatness he was having and his legs became strong as well. His shirt started to rip apart as his chest started to balloon out to form two very large breasts, and his shirt was thankfully ripped enough to provide as a temporary bra. As he changed, he saw Lena's panty-covered booty out and thought of this as his one chance at having revenge on her for starting all this. He gave Lena's butt a sharp spank and smiled as he couldn't wait to hear the sounds of well done revenge. Instead, Lena giggled and acted as if her mind had changed into become even more giddy than it was before!
"Ooooohhh, look at how cute I look being soooo fat! I love this!" Lena giggled. Vanessa and Taressa tried their best to refrain eating to give Rikki a stare (noticing not much has really changed about him now) of complete fear and surprise.
"Tell us....PLEASE tell us you did not just spank Lena's butt..." Vanessa said, fear growing in her voice.
"Uh....how about I say no and pretend I didn't...?" Rikki said, joking around a bit. Then he heard another slap being sent, this time to Vanessa. Her expression immediately changed from fearful to giggling happiness.
"Oh my! Look at how fat and busty I am! Tee hee hee! I feel like flaunting it off and showing off how sexy and fat I am!" Vanessa said, bouncing and eating at the same time.
"This is bad! I gotta go and--" Taressa's sentence ended as she got slapped on the butt as well and soon she was giggling like her other two sisters. "Hee hee hee, I'm such a big fatty bear! So fat my panties are showing right now! I sooooo love this!" She giggled.
Rikki knew more than enough to realized what's going on. Hand+Butt=Butt Slap=Mind Changed To Suit The Form. Rikki tried getting up and waddling away but...
"Oh no you don't, you fatty cutie, you!" Taressa said and gave Rikki's butt a biiiig slap! Rikki paused in his tracks as his changes continued, his hands and feet turning into paws, his ears replaced with black fox ears, his hair becoming beautifully long as well as his eyelashes, and his face grew into a nice vixen muzzle as a big tail exploded from what's left of his pants. It seemed to be as big as a kangaroo's tail but as fuzzy as a fox's tail. Rikki murred as finally he felt himself finally become a full female and felt her big fat body, giggling like everyone else.
"Whoa! I never thought I'd look this sexy and cute! My undies must be REEEAAAALY stretched out, tee hee hee!" Rikki giggled, now a very cute, sexy, and especially fat kangaroo vixen hybrid. She yelped and giggled again when Lena pulled and snapped Rikki's undies.
"You've got that right, girlfriend!" Lena giggled deviously. All four girls completely ignored the antidote for the virus. They were too distracted and cared more for how they looked, how fat they were, and how much pizza was left. They all groaned after the pizza was gone.
"Awwwwww! We ate all of the pizza!!!" Vanessa whined along with everyone else.
"Hey! I've got an idea, let's join the rest of my family! They're still stuffing their faces in the diner!" Rikki chimed, giggling. "We can go as soon as I get changed into something else. Ripped clothes so don't look good on me!"
"I'll help with that!" Taressa said. "I just hope Lena and Vanessa won't leave without us!" She grabbed Rikki and took the Kanga-vixen upstairs and they soon came down seeing Rikki had gone through a little makeover. On the clothes side, she was wearing a green tanktop that covered her chest (and was also wearing a big bra as well), a big dark pink skirt and white frilly panties that could be easily seen if Rikki ever bent down. Her hair was done up nicely and she also had a bit of makeup on, which was also done nicely and accented her good looks. After many compliments about how Rikki looked, the four fat girls waddled their way to the diner, where they met and ate with Rikki's family as well, who all looked just as beautiful as Rikki did, almost.
The Kangavixen took a nice walk to her friend's house, eating a big bag of chips as a snack. Rikki giggled as she was about to spend some time with Vanessa since everyone else was doing something and Rikki had nothing else to do. She walked in without having to knock and yelled for Vanessa.
"Oh Vanessa! I'm here!" Rikki said in a sing-song tone. Vanessa immediately ran down and hugged Rikki and started hopping.
"Hi Rikki! My, how fat you've gotten since the last time we saw each other of cour--" Vanessa had bounced too high now and hit the ceiling hard, with Rikki. Both women help their heads and groaned.
"Uggggghhhh....Vanessa....are you alright?" Rikki said, clutching her head in pain.
"Yeah, I think so......" Vanessa responded, then both girls jumped.
"THE ANTIDOTE!!!!!!" They both yelled and immediately ran to the lab. Soon (after a strike to Taressa's head) the trio had finally formed an antidote and preceded to spread it around the city, changing everyone back into the way they were and curing the virus once again. They all sighed once this was all over...
"Oh god, we finally did it..." Rikki said, breathing sighs of relief.
"I thought this time it couldn't be done..." Taressa said. Rikki looked on at the two of them.
"This time? You mean this thing actually happens often?"
"Quite often..." Vanessa sighed.
"Well...guess there's one thing left to do." Rikki said. Then the three of them agreed that Lena deserved to be punished, and after that, Rikki said farewell to Vanessa and Taressa and walked home, then he snuck off to a dark area in the neighborhood and took out a syringe carrying his own strand of the AF Virus, made to only change him and no one else. He smiled as he injected himself and walked out as the beautifully fat Kangavixen again and giggled as she walked home.
"I think this won't be the last time I see those two sisters again..." She giggled.
