[Longbow9]

“Why would that…”
Fiora suddenly became aware of a calamitous din coming from the hall outside.
“What’s all that screaming?” she asked.
“I suspect that’s the guards, come to stop us from escaping.”
“How do we fight them?” Fiora struggled against the still monumental weight of her breasts.
Cassiopeia didn’t answer, instead buckling on her breastplate and striding over to the open door.
“Halt, prisoner!” a mousy guard with thick glasses appeared at the entrance, leveling her laser rifle at the princess.
Cassiopeia put up her hands.
“Okay now, prisoner. Don’t move, or I’ll shoot…” said the guard.
Cassiopeia didn’t move, but the guard’s chest began to swell up. Surfboard to double E in no time flat.
“Wh-what’s happening?” she cried, her fat tits now bursting at the seams of her uniform. “Aaaaaa!”
The guard’s fatigues exploded, spraying buttons in all directions as her breasts burst out of her top. Within seconds, they were too large for the girl to carry and she collapsed to the ground, her gun completely immobilized beneath her vast cleavage.
Outside in the hall, there were more than a dozen guards suffering the same fate, collapsed on the ground or pinned against the walls, struggling to move beneath their enormous, heaving breasts.
“Fiora, are you small enough to move yet?” asked Cassiopeia. She looked back. Not yet, but they was getting there. Fiora’s tits had gone from colossal to merely titanic, but they were still bigger than she was.
“Princess, why am I shrinking?” asked Fiora.
Cassiopeia smiled at the question.
“Remember how you noticed how all the guards in this place were flat chested?”
“Yeah?”
“Well, I figured out why. I knew there was no way known to science to generate such high levels of breastonic radiation. I figured Cyberface had discovered some new technique, turns out he just cheated.”
“‘Cheated,’ how?” asked Fiora.
“He didn’t generate the particles. He harvested them.”
“From who?”
“The guards, of course. They’re all flat-chested because their naturally occuring particles have been drained dry,” explained Cassiopeia. “Which is good news for us.”
“Why’s that?”
“Because every guard in this place is carrying a positive breastonic charge. We’ve been oversaturated, so we’re negatively charged. Any guard that gets near us will absorb the radiation from our bodies.”
Sure enough, as the guards outside in the hall grew larger, Fiora’s tits grew smaller. It wasn’t long before they were back to the size of jumbo beach balls.
“What about your boobs?” asked Fiora, pointing at Cassiopeia’s watermelon sized tits, crammed comically into her undersized breastplate.
“The breastplate is holding all my particles in for now. I figure I’d hold onto them in case I needed them…”
“It’s your body…”
“Can you move yet? We need to get out of here.”
“I think so.”
Navigating the narrow passage outside the cell was a tricky exercise. They had to squeeze their way through a gauntlet of gargantuan gazongas that were nearly as large as they were.
“If all these girls are positively charged from having their breastons harvested or whatever, why don’t they just grow until they’re back to their normal size? Why would they keep growing?”
“My guess is they’ve been harvested repeatedly for years. The effect is cumulative. Each of these guards has a breastonic debt of hundreds of pounds worth of boobs.”
“Or more…” observed Fiora, as she squeezed herself around a particularly large pair. The girl trapped beneath them groaned and tried to grab Fiora’s leg, but it was a futile effort.
“Will they be okay?” asked Fiora.
“Eventually. We’ll be long gone by then, though. Come on.”
The pair swiped a keycard from a guard laying helpless beneath a pair of boobs the size of boulders and made their way up the stairs into the main facility.
“No alarms yet, I guess they were all caught by surprise,” said Cassiopeia. “Follow me, I think I remember where they hid our guns.”
The princess led them down a side passageway and Fiora jogged along behind. They hadn’t encountered any guards in a while so Fiora’s boobs had quit shrinking.
“Could we please slow down?” she complained, struggling to keep her beach ball sized chest from bouncing wildly with every step.
“Shh, it’s around this corner, I’m sure. See?” Cassiopeia pointed to a sign stenciled on the wall next to them.
“Armory.”
The princess peeked around the corner, staying as flat as she could against the wall (which wasn’t very flat at all, given the circumstances.)
“There’s a guard,” she said. “Fiora, come a little closer…”
Fiora tiptoed closer to the princess.
Sure enough, no sooner had Fiora approached the passageway than the sentry outside the armory began to grunt with discomfort.
“What’s going on?” she yelped, looking frantically up and down the hall. She tried to adjust her bra, but her chest was growing too fast. In mere moments, she was every bit as big as Fiora had been, while Fiora had finally shrunk down to her normal B-cup self.
“Ohh, tiny boobies, I missed you so much!” cooed Fiora, tweaking her tiny, pert nipples.
“Wait here,” instructed Cassiopeia, disappearing around the corner.
“You there! Halt, wait!” commanded the guard, struggling to unsling her rifle. The strap was too well embedded in her cleavage to be removed, and it was child’s play for the princess to incapacitate her.
Cassiopeia tied the guard up with her own belt and stuffed her mouth with a gag made from shredded fatigues before availing herself of the armory’s bounty.
“Ah, my D-ray gun! Did they hurt you my sweet beauty?” the princess purred into the bulbous ray pistol that was her favorite toy (that didn’t vibrate, anyway).
Fiora stole a camouflage top to hide her modesty, then proceeded to load herself up with every weapon she could carry. She stuffed her pockets with grenades, clipped a pistol and holster to either side of her belt and slung a laser rifle over her shoulder.
“Aren’t you gonna arm up?” asked Fiora.
“Nah, this baby’s all I need,” Cassiopeia grinned, stroking the D-ray. “Besides, I think you’ve got it pretty much covered…”
