"Isabel!" chided Layla, putting her hand over the ginger's mouth. "Think before you speak!"
Isabel mumbled angrily in a muffled tone behind Layla's hand.
"You'll have to forgive Isabel", said Layla, "she's got a big mouth and she can't keep it shut".
In response, Isabel opened wide and engulfed Layla's hand. Her cheeks bulging like a chipmunk, she then swallowed hard, sucking Layla's arm down her throat.
Layla did not seem shocked or surprised, only mildly annoyed. "See, that's what I mean", she said, rolling her eyes. Isabel merely opened even wider and gobbled up Layla's head next. Then, holding the engineering student firmly in her freckled, scrawny hands, gulped her down, working her way down Layla's body until her feet had vanished into her mouth.
"That was - urp! - good", said Isabel, smacking her lips.
Nant stared as the ginger's enormously swollen, pale belly. As they watched, it shrank and vanished completely, leaving Isabel with the same slim figure she had at the beginning.
"Must you be so greedy?" said Angel, stretching out on the floor lazily.
"Got a problem with that?" said Isabel defensively, putting her hands on her hips. "Got something for me to eat?"
Angel raised her skirt up, exposing bright purple panties. "Hope you're hungry~"
Nant fluttered their wings nervously. They weren't sure what was going on, but it seemed to be completely out of their control. Isabel grinned and got to her knees, pulling Angel's panties down and eating her out loudly and enthusiastically. As Angel moaned, she held Isabel's head and pushed her in deeper. And deeper.
With a wet slurping sound, Isabel's head vanished inside Angel's vagina. Her moans turned to screams of pleasure as she pulled the slim freckled woman in, slurping her up into her womb. As she laid back, holding her massive, squirming belly, it too shrank away, leaving no sign of Isabel having ever been there.
"So this is just going to keep happening, isn't it?" said Nant.
"What is?" said Angel, sitting up.
"All of you disappearing inside each other like nesting dolls".
"Technically they're called Matryoshka dolls", said Kim.
"Stop being an ass, Kimmie", said Angel.
"If you say so", said the short, nerdy girl, pushing down her pants and panties in one smooth movement and sitting on Angel. Literally. Angel's head vanished into Kim's ass with a pop, making Kim giggle and coo. Then she kicked her legs off the floor, letting gravity help her sink down over the psych major. Angel disappeared into the smaller woman with surprising ease, distending her like a balloon. Only Angel's legs were left sticking out, and Kim got on all fours and pulled them in with a little exertion before sitting on her huge belly triumphantly.
That belly rapidly shrank and flattened out in turn, and Kim got up and patted her flat stomach. "Aw, why couldn't she give me bigger boobs?" she complained.
"I got some right here if you want them!" said Michelle brightly.
"Ooh, thanks! Let me see!"
Nant watched helplessly as Kim fondled Michelle's breasts, then took her glasses off and stuck her face in her cleavage. And - as Nant had come to expect - Kim was sucked into Michelle's cleavage, as though it were a black hole. First her head, then her body, then her legs disappeared into Michelle's bust, which swelled to absurd proportions before returning to its normal size.
"Phew, that was good", panted Michelle, blushing from the experience.
"Seems like a good time", said Chloe, smiling from her position on the couch.
"You bet. Feeling hungry?"
"I could use a snack".
"Open wide!"
Chloe opened her mouth and closed her eyes, and Nant stared as Michelle literally dove down the curvy nursing major's throat. There was no swallowing or sucking or slurping - Michelle vanished in seconds, and Chloe's wriggling belly was flattening out again almost immediately.
"That was good", said Chloe, covering up a burp. "How about you?"
"I-I'd rather not eat or be eaten by anyone, thanks", said Nant nervously.
Chloe smiled gently and twirled her curly hair. "You know, Isabel was right, you ARE two people. Want me to fix that?"
