[Longbow9]

Fiora and Cassiopeia lay sweating in each other’s arms for several minutes, watching the porthole alertly for any sign of their guard. No face appeared in the window.
“Damn,” Cassiopeia growled. “I guess I didn’t get you to be loud enough. Now we’ve wasted all that time…”
Fiora’s breasts were truly immense now, each one larger and heavier than the whole rest of her torso. Cassiopeia’s had grown as well, pushing the double E range. Her breastplate was beginning to pinch uncomfortably, and it was becoming difficult to breathe.
“I’m sorry, ma’am,” panted Fiora. “But, if it’s any consolation, I was fairly loud by my standards. Usually my orgasms are more… modest.”
“You’re right,” sighed Cassiopeia. “We’ll have to try again.”
“I don’t know if I can be any louder this time, your majesty,” Fiora propped herself up on her elbows, fighting the titanic weight of her rapidly swelling tits.
“Not you, dummy. Me!” the princess flipped over and lay back. “I’ve always been a bit of a screamer.”
“’A bit?’ Your majesty, we share a wall. I can tell which vibrator you’re using by the pitch of your squeals.”
“Well, let’s see what pitch you can get out of me, then, because this might be our last chance.”
Cassiopeia pulled off her shorts and tossed them onto one of Fiora’s breasts. It landed so that one of her nipples poked up through the waistband.
“Ten points,” smirked the princess “Now it’s your turn to score.”
Fiora pulled herself across the floor. Her tits were the size of yoga balls now, and too firm to manipulate easily.
“I don’t know if this is going to work. If I turn over on my stomach, there’s no way I can get anywhere near your… hoho. These beastly things would hold me up like beanbag chairs,” said Fiora.
“Then I guess my ‘hoho’ will just have to come to you. Lie back.”
Fiora did as she was told. Cassiopea pulled off her panties and tossed them aside before straddling Fiora’s head and cramming her face between her thighs.
“Mmrrrf mrrrm!?” Fiora tried to ask through a faceful of royal muff.
“Just shut up and dive in!” laughed Cassiopeia, leaning back into Fiora’s cleavage like a massive, pink recliner. She grabbed a hold of Fiora’s nipples for support and began to stroke them up and down in sympathetic motion to the sensations she felt down below.
Fiora was as skilled with her tongue as she was with the controls of a starship, finding and attacking the princess’s swollen clit with a barrage of short, quick flits, spaced out by long periods of deep sucking.
“Ohhhhh God yes!” yelled Cassiopeia, already feeling the pleasure building up inside.
Fiora forged ahead, sucking her master’s clit into a frenzied ecstasy as royal honey dripped down her chin and across her face.
“Just like that, just like that!” the princess moaned, grinding her pussy on Fiora’s face.
The pleasure was intense. If she’d known Fiora was so skilled in the art of eating pussy, she never would have spent all that money on dildos!
“Make me scream and I’ll double your salary!” moaned Cassiopeia “Fuck! I’ll triple it!”
She bucked like a bronco as a spasm of pleasure shot from her clit like a lightning bolt. Perspiration dripped down her face and pooled in her cleavage, now so tight against her breastplate that she could hardly breathe.
“Aaaaaargh!” she groaned. The straps of her breastplate dug into her sides and she struggled to loosen them. Working with sweat slick fingers, she let out some slack, allowing her to breathe. Her breasts began to grow faster, filling the newly available space.
She felt the singing vibration of orgasm building up inside her loins as Fiora lashed out with her tongue, setting every nerve on fire.
“Oh…ohohhhhooooooooaaaaAAAA!” Cassiopeia screamed as the first wave of climax washed over her. She could feel it lapping at her insides like an ocean, building up into a tidal wave.
Outside the cell, curiosity had finally gotten the better of their guard. Neither Cassiopeia not Fiora noticed, but Blondie now had her nose pressed against the window, breathing fog in twin streams down the glass. She had her pants down around her ankles and her rifle slung back across her shoulders as her fingers worked furiously beneath pink, frilly panties.
I guess they wanted to go out with a bang, she thought, licking her lips at the delectable sight.
Fiora’s tits were as big as she was, now. Each one must have weighed a hundred and thirty pounds. They bounced with every spasm of Cassiopeia’s body and quivered with every little shudder.
“This issss… ooohhh ahhh… this is the big one!” yelled Cassiopeia.
Fiora locked her arms around the princess’s legs and held her close, fighting the involuntary motion of her master as she writhed in delight. Her tongue slid across her master’s soaking pussy and teased her throbbing clit, building to the big finale.
“Here it comes!” Cassiopeia screamed. The third wave of orgasm hit her like an earthquake, she could feel it rattle her bones. Blood thundered in her ears and she realized she was laughing so loud, her throat was practically raw.
“YEEEEeeeeeeeeeaaaaaaaaaaaaaaaaaaaaaaaaahahah ha!” she howled, pitching backward and falling into the canyon between Fiora’s towering tits.
For an eternal minute, Cassiopeia could do nothing but listen to the ringing in her ears and moan quietly to herself. Finally, she pushed her way out from between Fiora’s outrageous knockers and up into a sitting position.
That was when she noticed Blondie.
The guard’s face was flushed, with red marks on her forehead and the bridge of her nose from pressing against the glass. She’d obviously been masturbating. Cassiopeia didn’t need to see anything but the wild look in her eyes to know that. The princess shot the guard a come hither grin and beckoned with her finger.
“Sit tight, Fiora, we’ll be free in no time,” said Cassiopeia through her smile.
But, to her surprise, the guard just shook her head.
Cassiopeia and Fiora couldn’t make out what she said through the glass, but Cassiopeia got the gist.
“I’m not falling for that old trick,” she’d said. “I had my fun out here. Thanks for the show, though!”
The guard disappeared beneath the porthole as she retrieved her trousers. When she popped back up, Cassiopeia flipped her off. Blondie only winked in response and blew her a kiss before moving completely out of sight.
“Did it work, is she letting us out?” asked Fiora.
“No…”
Cassiopeia groaned and extricated herself the rest of the way from Fiora’s cleavage.
The floor was slick with their sweat, and the princess’s boots squeaked on the wet steel as she walked across the room to retrieve her panties.
Fiora propped herself up on one elbow.
“These are starting to get pretty heavy,” she griped. “What do we do now?”
The princess let out a sigh.
“Nothing. I’m out of ideas.”
“So that’s it? I’ll just lie back until my boobs grow big enough to smother me?”
“Here, you’ll have more time if we get you on top of them.”
“Great, I’d much rather be crushed against the ceiling.”
With much grunting and cursing, the pair were able to work together to get Fiora on top of her sofa-sized breasts. They were too heavy for her to stand up, so she folded her arms across the tops and leaned forward into them.
Cassiopeia sat down next to her and rested her head against one of the monstrous melons.
“I’m so sorry, Fiora. This is all my fault. I should have listened to you when you told me this sector of space was too dangerous. I let my pride get in the way of my judgment and now we’ll both pay the price…”
