In and out they went, plunging deeper into those tight and slippery holes every time. That ass was so tight, but Ursula persevered, wanting to hear this bitch scream her name. Her jiggling cheeks smacked against both of her tentacles with each thrust. Feeling those soft mounds against her extra limbs was almost as satisfying as feeling what lied past of the girl's newly formed anus.
Then the second tentacle came into play, finding a new way to make this slut howl.

"AAH!" Ariel cried out every other second. A sudden force came up that big thing Ursula's tentacle was fucking as another one started smacking those round cheeks. It hurt at first, but just like everything else, the pain was short lived as each spank sent a shiver up Ariel's spine.
"YES! OH URSULA HIT ME!!! I'm a filthy girl!" she spoke.

Ursula was glad her meal was enjoying herself as her body was thrashing two and fro, longing to feel an even greater pleasure. Granted, this same effect could be had if the girl was begging her to stop and thrashing in pain, but both were just as nice. One of her tentacles squeezed the Ursula's melon hard, her nipple now rock solid. If she wasn't so hungry, she might have kept this one as a sex slave. Her beauty would even lure even more sailors to their doom into the abyss. Ursula's belly.
When this was over, and this horny bitch was fighting for her life in her gut, she was going to cast a similar spell upon herself. One that would give her legs, but allow her to still breathe underwater, so she could feel what Ariel felt right now.

The little mermaid howled at the top of her lungs as those tentacles somehow went even deeper inside her. One felt like it was reaching her womb and another was so far up her ass she couldn't believe it. She barked like a dog in heat, thrashing her upper body as much as she could inside Ursula's esophagus. Her naked breasts rammed and grinded into the throat walls, actually increasing the level of pleasure she felt. All the while, in this haze of hormones she vaguely noted a pressure rising up inside her.

Ursula sucked loudly on her form, again pretending she had the biggest cock in her mouth. The girl was just so delicious and in a spurr of the moment she swallowed again. The brat didn't even notice that she was sinking deeper into the witch's belly, two busy screaming with her eyes shut.

Finally Ursula's tongue came into play as the mermaid's waist entered her maw. The moment she felt something else long and slippery inside her, Ariel screamed to the heavens once again. It wouldn't be surprising if every fish in the sea could hear her at that moment. She felt like her entire body was on fire, something from the surface that she knew burned, and she felt something explode between her legs, and into Ursula's hungry mouth.
