After The Enbiggener failed to immobilize Supergirl, she decided to change plans! She couldn't stop and just Supergirl, she had to get ALL superheroines! So, to ensure no one stopped, she began kidnapping heroines and fattening them up before any help can arrive.
GULP as another mouthful of the Enbiginner's Enbiggining Sauce forced its way into Batgirl's mouth, she couldn't help but swallow it. She desperately wanted to spit it out, but the stuff was just too good.
Just as she thought that, the machine started to whirl down and the sauce eventually stopped pumping into her mouth. Confused, Cass strained her head and all 4 massive chins to turn and look at the woman who ordered the machine to stop. The Enbiginner.
"I must comend you for holding up so long, Batgirl. It's not everyday someone can take almost 500 gallons of my special sauce, and still be lucid enough to glare at me with such hate-filled eyes. You must be so disciplined, well, too bad all of that discipline and training will be for naught, as I'm about to pump that last 100 gallons straight into your oversized gut! And unlike the last 500, I'm doing it at a much faster pace, so enjoy this little break who it lasted! Hahaha"
"M-Mhaa!" Cass desperately cried out through the tube in her mouth and the mouthful of sauce she had yet to swallow as the machine whirled back to life, and more of the sticky green sauce began to pour into her face.
"What was that? More? Well, if you insist~" The Enbiginner laughed as she hit a button on a remote, causing the pump to start pumping even faster.
All Cass could do was just continue to swallow the ever-flowing cascade of sauce, taking short and shallow breathes in between each mouthful. As she took in more and more sauce, Cass could feel herself plumping up more. Her skin stretching to contain all this new fat that was rapidly being put on, covering up all of her previously well-defined muscles that she'd gained from years of intense training. She could hear the strain of the four cables, struggling to hold her up be her limbs, they could break any second. Her growing gut, growing fatter than any other part of her, filled with sauce, and covered in fat and little else, as her suit began ripping long ago.
"Mwahahahaha! Supergirl might have been able to escape, but you never will, Blubber Girl!" The Enbiginner laughed as the machine kept pumping.
Batgirl did not know how much longer she could take this, but the sauce made her love every second of this, and it made her want even more.
The End
