The Bumps in the Night

He didn't know what to make of the rattling noise, but he knew he should wake up to investigate it. Timmy Turner wasn't usually the kind of kid who cared went bump in the night now that he had fairy magic to protect him, but magic or no magic, some strange noises needed investigating.

The bowl was moving, sliding back and forth on his nightstand as Cosmo and Wanda giggled inside. After a few minutes Timmy heard screams, what he soon realized were moans instead, and his face turned beet red.

He knew what was going on now. And he couldn't get back to sleep even if he tried.

Inside the fish bowl...

Cosmo took the form of a vibrator as Wanda lay tied up on the bed. They took smaller forms of themselves to be able to fit properly inside their tiny fish tank bedroom, but their bedroom antics were still as rowdy as always. Cosmo plowed into her, using his whole body to hit every spot imaginable inside her vagina.

"HARDER!" Wanda cried, shaking the bed as she pulled at her restraints.

Cosmo knew what this command meant. He changed shapes, turning from a vibrator into a large gorilla dick, a flaccid one. He let her movements engorge him, filling Wanda on the inside. She moaned, her juices finally flooding him out.

Cosmo looked up as he took his own minature form. Wanda nodded and Cosmo shoved his rock-hard cock into his wife. It was nothing now compared to what he'd just been doing to her, but magic cured all things. He used his wand to make his cock the size of a small building, and Wanda writhed under him as Cosmo thrust over her.

Finally in a wave of ecstacy the two came together. They undid their bindings and returned things to normal, cuddling together as two innocent-looking fish inside the bowl.

"Do you think he knows?" Cosmo asked.

Wanda laughed, "That oblivious little shit? No way!"

And though Timmy knew, he never told them. He knew it was better to keep it to himself.
