Roxie and Experimenters

Roxie was sitting in a stark room, resting on a soft bed, while polishing off her second pizza. Her first was finished before she realized how hungry she was. Then, she finished off her soda, and belched loudly.

"Excuse me," Roxie said, despite being alone in the room. Then, the sliding doors opened, revealing a person in a white suit. He appeared to be wearing a sleek helmet to match it, and he had a stun gun equipped.

"Roxie, Nattie has sent you your terms."

"Terms?" Roxie said, as she started on eating a dessert.

"I'll just summarize it for you." He let out a deep sigh, and then said, "Firstly, you are to partake in any and ALL experiments that Nattie requires." Before Roxie said anything, he added, "Without question."

Roxie swallowed some food, and laid her hand on her soft belly.

"Secondly, you are forbidden to leave. Doing so will alert the laser snipers, and you will be brought back here. Third, you are not to associate with anyone except for Nattie, or unless she cites otherwise. Questions?"

"Well, not really. More of a--"

"Good. Then you'll do fine."

The guard hoisted her from her seat, with little effort, as this man was fairly fit. He pulled out a device which looked like a radar gun. The difference was that it displayed the target's immediate weight.

"269." He said, "Come this way, Roxie."

Roxie was trying to avoid strangling someone. Here she was, marching behind her guide, in nothing but a blue bra, and matching panties. Meanwhile, everyone else--including Nattie--were clothed.

The large area that she saw before her had to be a secret laboratory. The only color she could make out was white, and oddly enough, it reminded her of an old cartoon. The quick tour ended when Roxie was led to a collection of 12 different staff members.

"Nattie, the test subject is here."

"Good," Nattie said, using the joystick on her hovering chair to move her 1000-lb. body around. She said, "Now, today's experiment will involve a new piece of underwear. It's in that box over there."

After a second or so, Roxie sighed, and headed to the box, opened it, and got the gear.

"Good..." Nattie said. "Now, go to a decent area, and change, won't you?"

Again, Roxie did as she was told. Once in the bathroom, she took a look at her body. Perhaps, switching bodies with a chubby cashier wasn't a good idea. She had a couple love handles, a softer belly, which hung a bit like an apron, and she had large, thick thighs. She had a pudgy, round face, along with cute, boyish, black hair.

"I can't believe I'm doing this..." She said, as she headed back to the area.

Once she returned, some of the staff members did their best to show self control. Roxie let her hands fall to her side, and wore a blank face.

"Good, now we can begin." Nattie nodded, while a scientist began working. "Now, Roxie, what you see is merely an expansive tool. We call it the Mega-Sizer, simply because that's what it's going to do. I plan to release this eventually, but we love to make our things certified and all of that. That panty is wirelessly linked to an advanced program. All we have to do is decide, by what percentage you begin your expansion."

"We're all set, and everything looks good!"

"Good," she said. "First, try a little 25% increase."

After he input the data, and pushed a button, Roxie's butt started to expand accordingly. It wasn't anything drastic, but it was startling. Roxie eventually felt her expansion stop, but she felt like she had a coiled tail on her rear. The fact was that it felt more like someone taped a little more extra padding to her backside.

"Oh, my!" Nattie said, laughing with delight, "Roxie, t-take a seat, won't you?"

Roxie sighed, and took a seat, but now it seemed like her buttocks were trying to flatten the chair she was son. After all, it was only a classroom type chair that they used.

Roxie was trying to think of an escape.

"Okay...bring it up to 70%."

"Wait--" Roxie started to say, before she felt a tingling vibration. Suddenly, hips, thighs and rear expanded much more. It got so that was able to flood a square table with her hindquarters. She strangely noted that her belly was coming out, just a bit more.

"Good...But, we need to see if this works on supernaturals..." Nattie said, thinking of another experiment.

"Super-what?" Roxie said, sensing something weird.

"Nothing. Our tests were complete, so you may report to the dining area, and eat until we need you."

-----------------------------------------------------------------------------------------------------------------------------------------

And so, Roxie was sent to a lone table (with her still monstrous rear), where one of the other people said, "I want to impress the boss, so..." He looked at Roxie, and said, "I've developed a serum that's supposed to magnify someone's hunger. Well, to the point where they'd need to eat like giants to sate their hunger."

"I've already been tested on," Roxie said, upset, and still in the midst of her feast.

He disregared this, and injected the serum in her. But Roxie was quicker and took hold of his hand, just as he was applying the dose. Suddenly, a light began to glow, and all of a sudden, Roxie was the scientist, and that scientist was now the big-bottomed test subject.

She quickly ran out. This was her first swap with a man, though it was necessary to avoid any complications, and just like that, she heard bloodcurdling noises. She looked back, and saw her old body growing mysterious appendages, in addition to gaining weight in a mysterious fashion. Every second that passed, a new arm came out of said body. This ended when there were about 4 arms in total. However, there were several curious pointed warts on the skin.

"AAAAAAAAH!" The new owner of her old body screamed.

"That'll learn him," Roxie said as she ran.

Once she got out of the doors of the laboratory, one of the gatekeeping snipers detected a guard with a Swap-Bracer, and alerted Nattie.

"That's Roxie! Get her!" She commanded.

Roxie had to get out of there for good, and she quickly took a motorcycle and fled.

"Roxie got away," one of the scientists said to Nattie. She growled, but then saw the victim hanging around in the dining hall. Roxie's mutated body was busy devouring any and everything at an alarming rate, due to the extra arms (not to mention extra stomachs that somehow appeared).

"Wait, I still see a use for this one yet..." Nattie said softly.

----------------------------------------------------------------------------------------------------------------------------------------

Just as Roxie was finished escaping, she passed by a 2 story apartment, but heard some calling for her.

"Oh?" She said, stopping to answer him. She saw an elderly woman sitting in a lawn chair. Her eyes were covered by a dark-looking hood, which matched her equally dark looking robe.

"Come closer, child..." She beckoned.

Roxie said nothing, but then the woman said, "You must be one of them."

"One of who? I'm not sure what you're talking about."

"Your bracer...and the gem..."

"Yes...?"

"The gem has granted countless people the ability to shape other people the way they see fit. You also have this...which means...we might not suffer."

"Might not suffer? What do you mean?"

"Ah...there is much to discuss. Come."

Suddenly, Roxie walked into the home, and closed the door. Nattie's scientists missed her completely, and were practically chasing a ghost at this point.

-----------------------------------------------------------------------------------------------------------------------------------------

"...So, you see, in time, people used this Shift Gem to shape other people. Your bracer contains that same gem. I made that gem."

"Really? So..."

"However, you aren't using it to its full potential. So far you've shaped other people by body switching...so I'm thinking..."

"Yes...?" Roxie said, trying to decide if there was anything to gain.

"Why don't you do something for me?"

"Um, sure." Roxie said, eating one of the cakes on the table.

"Take someone's body and meet my requirements. I'd do it myself, but...well...it should be fun for you."

"Sounds like a science project."

"Perhaps, but I'll grant you a fantastic reward for doing this."

Roxie shrugged and said, "Sure."

"Good...Now, first, I want you to take the body of young lady, and bring it back to me...fatter."

Roxie jumped out of her seat. "W-what? You want her bigger?"

"Oh, of course." The old woman said, "I'd love to see one like that, so I can appreciate the beauty in such a specimen. I was told by my late brother that he loved fat women. I'd like to see the appeal. You'd do this for me, won't you?"

Roxie gave some thought and said, "Sure, but I hope I don't come off as random..."

"Good...You may begin when ready. Just remember to return to me, when you think you've done a good enough job."

"Will do," Roxie said, as she left. She looked at her Swap-Bracer and saw that the gem on it was glowing a little brighter.
