The AF Virus, ENHANCED...

Rikki woke up from bed, smiling at a new Saturday morning and got dressed and had breakfast. He was smiling because today he gets to meet his 2 friends, Vanessa and Taressa. He's seen them a lot on his ways back from school, and he's even talked to them a few times and now he's able to arrange a visit to them, and he cannot wait. He packed up his laptop and DS and headed off. Meanwhile, Vanessa and Taressa were getting ready for their visit and also tried making their lab Lena-proof.
"There! That definitely should keep her outta our business for a while." Vanessa sighed, finishing the new security program on the doors of her and Taressa's lab.
"You'd better be right! We certainly don't want her in our hair especially since Rikki will be visiting us for the first time. Now, we better get dressed for our visitor." Taressa said, the two of them getting dressed outta their nurse clothes and in their normal ones, then exited the lab. Afterwards, Lena seemed to popped here outta nowhere and almost tackled them.
"Hi! I hear someone's gonna visit us! Can I give him a tour?!" Lena yelled gleefully.
"NO!!!!" Vanessa and Taressa yelled. "We don't want him to run away from us, so stay away from him!"
"Can I at least go in your lab?"
"Again, NO! Besides, you wouldn't be able to get in if you tried. We added a security program to make the lab Lena-proof!" Vanessa said.
"Awwww, can't I do anything?"
"You can stay in your room."
"Aw, but that's boring! Tch, fine…" Lena said.
"There, now we're ready…" Taressa said. At that moment Rikki was knocking on the door. He smiled when he saw Taressa and Vanessa open the door and let him in. "Hello, Rikki! It's nice to see you here!"
"It's nice to meet you too, ladies. I'd love to see around your house, and-"
"HIIIIIIIIIII!!!!!" Lena said, glomping Rikki. "You must be Rikki! I'm Lena! Vanessa and Taressa's little sister!"
"Hello Lena. It's good to see you too."
Vanessa and Taressa immediately told Lena to get back in her room and Lena sighed as she did, but had a smirk on her face as she did.
"What was that for?" Rikki asked.
"Trust me, she causes nothing but mayhem. She should leave us alone…or else she's grounded." Taressa said.
"Oooookaaaay…" Rikki said.
"ON WITH THE TOUR!" The trio said. The sisters showed Rikki around the whole house, and now, there was one last thing left to see.
"You're really going to like this place, Rikki" Vanessa said as the Lena scanner scanned the three of them and allowed them in, and Rikki gasped at the sight of many items in the room.
"This is our hospital/science room. Here, we research on the transformation and expansion phenomenon. We've done a whole lot of experiments here…" Taressa said. Rikki then went to a certain Petri dish.
"Hey, what's this?" Rikki said.
"Oh, that's one of our past experiments, the Anthro Fat Virus. Thanks to LENA this thing once infected us, but we made an antidote for it and thus we are now perfectly fine. We had a little drawback with the fact that every hiccup changed us back, but we enhanced the antidote to take care of that." Taressa said. "That dish still has a little bit of the virus in there."
At that moment, Lena appeared outta nowhere and accidentally spread dust on Rikki.
"HIII RIKKI!" Lena yelled.
"LENA!? HOW DID YOU GET PAST-"
"ACHOOOO!" Rikki had sneezed into the dish where the AF Virus was held into. At that moment, Taressa and Vanessa ran to get their multi-microscope and them and Rikki looked into it at the AF Virus.
"Oh no…the germs in Rikki's sneeze, combined with the AF Virus…the virus is MUTATING! Wait, it's multiplying in a big rate, like it's gonna do something…" Vanessa said. Rikki was scared enough to see the virus multiply so fast so he ran outta the room. Unfortunately, once Vanessa and Taressa figured out what would happen, it was too late. The virus multiply at a burst of speed and then suddenly exploded and spread out into the air through a crack on the petri dish and infected Vanessa, Taressa, and Lena, changing them back into the forms they were when they were first infected, Vanessa being changed back into a fat kangaroo girl, Taressa being changed back into a fat beat girl, and Lena being changed back into a fat raccoon.
"Yay! I'm a raccoon again!"
"NO! We're fat again!"
                           ---------------------------------
Rikki heard the yells of everyone, muffled by the solid doors of the room entrance. Rikki waited, then opened the door to see a fat bear, kangaroo, and raccoon in there.
"Oh god…" He said. "Guys? What happened to you?" Rikki said, approaching them with his mouth and nose covered by his shirt to keep the virus from getting to him. "Is there any way I can-"
"DON'T TOUCH ANY OF US!!!!" Vanessa and Taressa yelled before Rikki could even touch them.
Rikki jumped back in fear. "Why?!"
"The virus is normally spread by touch…but good use for covering your mouth and nose! Who knows how else the virus can be spread now that's it's transformed?!"
Lena took the Petri dish and looked at it to see it covered with dust still…then tossed it outta the window. "Garbage." She said as she chucked it.
"NOOOOOOOOOOO!!!!" Vanessa and Taressa and Rikki yelled, but it was too late. The ominous sound of the Petri dish shattering in the ground was heard and immediately Lena got death glares.
"What?" The chubby raccoon girl asked.
"YOU SINGLE-HANDEDLY UNLEASHED AN OUTBREAK!!!" Everyone else yelled.
"Oh…hey Rikki! Wanna play TAG with me?" Lena said, completely disregarding the danger she caused.
"Uhh, no thanks, Lena! I-I'm good!"
"Aw! It'll be fun!"
"Lena, you'd better not!" Vanessa and Taressa said. But Lena didn't listen. "RUN, RIKKI!!!!!!!!!!!!!!!"
Rikki was a few steps ahead of them as he was already outside running. Lena was fast on his trail before Vanessa and Taressa could do a thing about it. Good thing Lena was fat, Rikki could run from her easily, but still, she was quick for a fattie. Meanwhile, Rikki saw how quickly the virus was infecting everyone. Everywhere he saw he saw many people become fat anthro animals, and plus, all of the males for some reason became female…and sexy. Just when Lena was about to catch Rikki, he shut the door to his house in her face and locked it. Then, he ran to the other doors and windows and shut and locked them all, then he went to his bed and gave a big sigh of relief. He then rested in there while the virus infects half of everyone else in the whole town…
