To piss on it.

"What ?" asks Brittany.

"It's like with jellyfish, the secret is piss. If you spray it with urine it will turn back to its egg shape. But given the size of it we will need a lot, all of you will need to piss in the pool. " you explain.

"You can't be serious! " interjects a moaning girl.

"I'm afraid so, it's the only way. Better get started soon because it will take some time with the mass of it." you reply. "I'll help those that didn't drink enough."

You go grab a garden hose that is there to wash the pool deck and spray the girls in the face with it on the pretense of letting them drink.

All of them blush as they let go of their bladder in the pool, of course you totally made up the thing and the only effect would be to have them sitting in their piss until the egg wears off.

You watch the scene, drinking a large glass of fruit juice. You got the idea from the fact you already needed to pee, but you get a feeling you'll need more.

"It's not working! I peed a little but it doesn't change, I am still stuck and it's still fucking me. " says Brittany.

"You know, this thing can barely fill a bucket normally. You just didn't pee enough. Of course with its size it could last for weeks. Do you want me to help you get out?" you ask her.

"Yes please help me!" she begs.

You strip down and go squat on the ledge of the pool facing her.

"Wait! What are you.... " she begin to protest, but she's interrupted by a stream of your piss hitting her in the face. It wouldn't be so bad if she could keep her mouth shut but her redoubled protestations only make her drink some of it.

You repeat the process with some of her more ardent supporters, filling glasses and throwing their content when they are too far away.

The concert of moans and grunts of the girls getting off from the creature is very loud and drown the few insults of those that received the secret cure.

You carress the surface of the pool with affection like you would a pet.

You go sit on the edge of the shallower part to the pool, not in it but with your legs spread offering your pussy.

You don't have to wait long for a few tentacles of goo to get out and claim both your ass and pussy.

"When will it stop, why doesn't it stop? " screams Brittany.

"I have no idea, I never wanted it to stop while using it. But it's a relaxation egg, it will stop once you're perfectly relaxed so stop stressing yourself and enjoy the ride." you reply.

"But what about the thing with the piss?" asks Vanessa.

"You really are dumb enough to believe that? I just wanted you covered in piss. As for our deal, you wanted to know the secret to get free from it, I gave it to you. Just relax and enjoy and it will let you out." you reply.

Most are about to protest but as if granting a wish of yours, tentacles gag them by making them suck on them. You even notice that they seem to pump liquid in them, yellow liquid.
