Ariel just moaned, soon hanging limply in the stinky air as she pushed past a ring of muscle that led to her mistress' magnificent tummy. That fat globe was like every other part of her body, round, soft, and it all made Ariel lick her lips right now.

Speaking of licking, Ursula's tongue was madly licking the slut's butt cheeks after she squeezed them into her mouth. The fatty hills were delicious enough on there own, but as her anal probe continued to shove her deeper down her gullet, it also found even more unexplored space inside the ass. Going in so deep kept a healthy supply of cum flowing into Ursula's mouth.

"Such a tasty little thing." Ursula thought to herself. It was then that her hunger had come completely back into the forefront. Her lust was brushed aside as the needs of her belly became center stage. That gut had provided her with such pleasure, even more than her own tentacles or even this slut. Inside her, living creatures had died inside her, struggling for life inside the fleshy sack and making her feel incredible. After a night of absolute rapture, she would awaken to find even more lovely curves on her body. New rolls of flab, all of which used to be someone, were now forever a part of the ever growing sea witch. This mermaid had made her see the light. Her belly was not only responsible for keeping her full, but it also provided her with ample opportunites like this to satisfy other needs. Even as her meals died they helped her bring about and satisfy her lust, and they made her already gorgeous self even rounder.

Even back before she was banished, Ursula was always quite the gourmet. They had such fantastic feasts when she lived in the palace. She was never a thin woman to begin with, but when she lost that steady food supply, her tummy longed for even more sustenance. After today, she was going to keep on eating. Sailors, Merfolk, fish and seagulls, all were now part of her Seafood Buffet now.
Before she'd been thinking about stealing the Trident and growing to a massive size. Perhaps should get that big the old fashioned way.

Returning to the whirlpool moved, the vortex in Ursula's mouth sucked Ariel's long and sleek legs along with many gallons of water. She swallowed everything in one gulp.

Ariel gave a brief shriek as she plopped down into her resting place. It was dark and the fishy smell was the most intense here, but she loved it. The stench and the abundant sea water she was wading in reminded her of the life she had given up and the knowledge that she was inside the core of her mistress made her even more happy.

"You satisfied me mistress, I only I provided you with as much pleasure." Ariel spoke softly, basking in the water mixed with saliva and her own cum. She felt completely content and now it was time to rest.
Nothing rose her from her state of peace, not even when the water became boiling hot.

*GURGLE!*
Ursula patted her vastly expanded middle as it groaned and churned it's meal. Her belly was now three times it's normally rather big size, forming one giant, black, fat dome that hung down to her tentacles. In the water it floated somewhat. Despite it's weight, it stayed up with the same principles that kept up an ocean liner, which ironically was the size Ursula hoped to be some day.

Her laughter bellowed into throughout the cave Triton's slutty daughter died inside her, making her even bigger. Soon she'd be of great ominous legend than the Kraken himself. She's follow in his footsteps though, sinking ships and letting no one go uneaten.
