Part 5:
As soon as they got through the crowd, Heather and Kimberly hit the buffet table hard. Feeling understandably full, Jennifer was not terribly interested in gobbling down extra food, and only nibbled on a strawberry as she scanned the crowd, unwisely left alone with Lisa.
Jennifer was in awe as Dr. Mooriboobi entered and Yumi's breasts grew to their spectacularly enormous size. She rubbed the tops of her own breasts wistfully, gazing with envy at Yumi's tautly engorged breasts. "I hope I can get that big," Jennifer whispered, "she's so huge!"
"Really? You're not too bad yourself," Lisa leaned in as close as their bloated breasts would allow. "How much bigger have you gone before?"
Jennifer started, making her engorged bust wobble. She hadn't realized that anyone was listening to her. "A bit," she blushed.
"Dr. X. told me not to say exactly how much. Have to keep some secrets," she giggled. "I just love being big, though. Feeling my skin stretch is just... mmmmmphh..." Jennifer closed her eyes and bit her lip as she moaned quietly and rubbed her breasts a bit harder. "Dr. X. Pande always makes me stop before I want though," she pouted a little.
Jennifer didn't catch the wry look on Lisa's face as she leaned over, smooshing her own enormous breasts, each almost half as wide as one of Jennifer's, into the side of the more bloated girl to nuzzle and grope her pontoon like breast.
"You are soooo big," she moaned. "I'll bet you can get gigantic! I wish I could get big like you. Even after adding four times my size tonight, I still won't be as big as you."
"Aw, I'll bet you can go big too! I'm signed up to add five times my size tonight. I wanted to go bigger, but Dr. X. said no. He didn't even want me to start out this big," Jennifer admitted, blushing deeper and patting the sides of her swollen breasts, making her taut skin reverberate like the surface of a drum.
"Really?" Lisa looked up, doe-eyed. "You know we can use the tablets to make ourselves as big as we want. If you wanted to, we could... No, I'm sorry - someone your size would never want to do that with me..."
"What's that?" Jennifer leaned in, making their breasts bulge out around each other.
"No, Nevermind...."
"Come on Lisa, tell me please?" she begged, squeezing in even more.
"Well, you can do a challenge with another girl where you both agree to go an additional size - all the top girls do as many challenges as they can, but I don't know how many girls will want to do one with me."
"I will!" Jennifer, ever friendly, tried to cheer her up. "What do we have to do?"
Lisa backed away, letting both of their massive busts bounce from the release, and brought the tablet up over her cleavage. "For now I'll just send you the challenge, and we'll grow during the opening reception."
Jennifer maneuvered her own tablet over her bulging slopes. "Oh yeah, there it is! Oh cool! And so now, what, I just switch back to the main screen, and here's the master size control... my size now is 1,500 liters, so I put in 3,000... Do you want to grow together? How big are you?" Jennifer looked up at Lisa expectantly. Lisa looked confused at first, but her expression quickly brightened as she caught on to Jennifer's mistake.
"What? We can just wait until the reception starts... But we could do it now if you want. My implants are currently filled to 250 liters, so I'll be 500 after." Lisa punched in the number on the tablet and looked back up at Jennifer. "Ready?" she asked.
Jennifer nodded enthusiastically, her excitement building by the second.
"OK! One...two...three!"
They hit enter at the same time, and both girls' breasts began bulging out at a terrific rate, although Jennifer's to a much greater extent - inflating like rafts on a high-pressure line.
"Oooooohhhhh!" both girls moaned out in unison, reveling in the feeling of their expansion.
Lisa groped the sides of her swelling breasts, squeezing them together as much as she could to accentuate the feeling.
Jennifer moaned louder as her enormous breasts bulged out to five feet each and continued to expand, soaring up to six feet in diameter. No longer able to hold her massive girth off the ground, Jennifer allowed her breasts to fall to the floor, bulging out more on the sides as she continued to grow and spread. Letting out a sigh to equal her epically inflating bust, Jennifer leaned forward into her own chasmic cleavage. She extended her arms to rub the tops of her globular breasts as much as she could, feeling her skin stretching as she leaned into them, causing her growing bust to bulge out even further on the sides.
Finally the girls settled into their new, swollen sizes and collapsed into each other, breathing heavily from the exhilaration. Lisa's almost three and a half foot wide, overstuffed, beanbag-sized breasts smooshed into Jennifer's bloated bust, causing her newly tightened skin to bulge out further around them.
