Things get nastay (but in the good way, like you want).

"Mmmm, you like that?" The goo asks as Hilda starts to come down.

"Mmmmyeaaah," Hilda whines between gasps.

"This is where things get really fun..." the goo says.

Hilda closes her eyes shut and concentrates on these wonderful sensations as the vibrations renew their assault on her body. Then she starts to feel something else.

The ooze is rubbing along her slit, and is gently parting her folds. Hilda tries to say something when she starts feeling something else pushing on her asshole.

Hilda's eyes spring wide open in surprise and shock as the goo penetrates both her holes simultaneously.

She tries to let out a scream (whether of pain or pleasure who can tell), but quickly finds her mouth muffled by another sloppy kiss from the goo girl.

But instead of pulling back like before, the googirl instead seems to expand out further around and inside of her captive. Her tongue seems to enlarge and take on a phallic-like shape, sliding to the back of Hilda's throat and oozing something past her gag reflex.

I should be terrified, but it just feels so good, like a a dull, soothing, fuzzy warmth.

Hilda's eyelids droop and she starts groaning in pleasure as she's triple-penetrated.

Down below the ooze has been spreading, and instead of going in and out of Hilda in swift motions like her previous lover (a rather large cucumber she had bought from the market) it's finding every nook and cranny within her nether regions and filling them out completely.

When it feels as though Hilda can take no more, the vibrations begin again.

Every nerve ending is on fire as she feels overwhelming pleasure all over and from inside her body. She tries to thrash about, but the goo girl is completely restraining her. Hilda tries to moan and mewl, but the intruder in her mouth prevents you. The muscles in her lower body try to squeeze and constrict around their intruder, but find nothing solid to get ahold of.

I've never felt so helpless before.

Her body spasms as she cums again.

And its never felt this gooooo-oooooooohhhhh!

Hilda's eyes roll back into her head as the orgasms start. Soon, she loses all concept of time and eventually blacks out.
