Helen kept her mouth clamped shut but smiled broadly as she hummed cheerfully. She enjoyed the feeling of the Pint Puncher's fading strength. He stumbled about her mouth looking for an exit, and she would be all too happy to give him one. But not quite yet. She felt the fight slowly slip out of him as the stench of her lingering belch sapped him of his super strength. Helen was not normally a patient woman, but she was quite enjoying this. The hippo tapped her fingers along her large belly, anticipating her rival's eventual destination.
She turned to face the bank tellers, whose eyes clearly revealed their terror. Her smile grew broader as she slowly ran her tongue across the hero's defeated body, enjoying his flavor one final time. "Mmmmmmmm," she moaned, before slowly swallowing the hero whole.
She exaggerated the motion of her swallow for the benefit of the bankers. She traced the path of the hero's body as he slipped down her throat and into her large gut. His strength gone and his mind nearing unconsciousness, the Pint Puncher wasn't able to do a thing to slow his fall. He found himself landing with a splash in a large, dark, wet cavern.
The landing stunned him awake. He quickly realized what had happened and pounded away at the walls of Helen's belly. His punches made her belly bounce, but did little else. She laughed as the bankers looked on as their hero helplessly tried to escape. The hippo rubbed her round stomach in delight.
"Some hero you turned out to be Punchy," she laughed, finally opening her mouth again. "Turns out you make a much better snack," she said, her chuckle turning into a full blown belly laugh, sending the hero sprawling within her gut.
He tried to take off and fly out the way he came, but found her body presented an iron clad cage. There didn't seem to be any escape for him. He looked down and his eyes shot open in terror as he realized that Helen's stomach acids had already eaten away most of his costume and was starting on his body. He didn't have much time left.
The pain was agonizing, but brief. Helen sat back and enjoyed his struggles as her body did it's work. From time to time she rubbed her stomach, basking in the glory of her victory. Finally feeling his struggles cease, she stood up. The hippo rubbed her large ass, as she was certain the fallen hero would soon add to it's glory and power. She turned her full attention to the bankers and dropped her empty money sacks on the counter with a wordless grin. Without a hero to save them, the tellers quickly emptied their vaults and Helen exited the bank with her largest score to date, not even including the Pint Puncher. She slept soundly that night, enjoying her greatest victory.
The next morning, Helen woke up and admired her curves in her full body mirror. She noticed, to no surprise, that her ass was a bit more plump than usual. "Thanks for that parting gift Punchy," she said, groping her cheeks as she laughed in delight.
Without a hero to stand in her way, Helen went on a crime spree like none other the city had ever seen. She eventually stopped wearing her purple panties and got a tattoo of a wrestler, clad in white with a white mask, on one of her massive cheeks. It became her trademark, and often it was the last thing her victims would see. Instead of celebration, the symbol of the Pint Puncher struck terror and dread anywhere it was seen.
