Mythia and her assistant Herb decided on feeding themselves in a potion feeding machine.
The two of them sat in separate seats in the machine and Herb looked like she's ready to get filled up.
"Should we try out this thing, Ms. Celtil?" Herb asked.
"Yes, my dear assistant," Mythia nodded.
They grabbed the light green colored hoses and Mythia pressed the button that said On/Off. The machine began making whirring noises as soon it activated and began processing the mixed potions in the giant glass container below.
"I'm ready Ms. Celtil!" Herb muffled with her teeth clenching the hose.
Then the potion flowed through the hoses and into their mouths. The process of them growing bigger was slow but worth it as their bellies began growing out of their clothes making them fatter and rounder.
Herb and Mythia became bigger inflated round balls as their bodies expanded a lot more huger than before. Soon their clothes were ready to burst and then suddenly... BAM! there they go; popped off like a dynamite!
After they were done and couldn't take no more much to their satisfaction, Mythia managed turned off the machine with her hand sunken deep in her body and rolled out to the floor.
"Quite the experiment it was, Herb," Mythia said becoming a giant round ball in her light green underwear.
"The best experiment ever made, Ms. Celtil!" Herb laughed and bumped her round body against Mythia's and is also in her dark green underwear as well.
Now the two of them become giant round lab partners and were satisfied with the way their newest invention worked out very well for them.
