With a massive dildo

One of the men grabbed Madison by the hair again and pulled her farther into the warehouse.

It hurt so unbelievably bad when they did that but Cunt Brain knew she deserved it. She deserved whatever pleased the men.

The dragged her into a big room with a couch and a camera and in one corner a nude girl lying curled up. The room smelled awful, like hot sex, and old piss. Cunt Brain understood that this was the smell of her future.

Lying all around the naked girl were a bunch of sex toys. One of the men grabbed one, a huge one, an enormous elephant-sized dildo and tossed it carelessly towards Cunt Brain.

"Do what comes naturally." He said.

Her mouth went dry, and her lips got wet as she stared at the monstrous object, its veiny surface and bulbous head taunting her. This was her chance to fulfill her purpose. With determination in her eyes, Cunt Brain took the dildo and shoved it into her mouth, gagging as its size stretched her jaws to their limits.

The men watched in amusement as she desperately tried to take the entire thing into her mouth, her throat convulsing around the shaft. It seemed impossible, and cunt brain knew that her inexperience at such things was on full display. But she refused to give up. Now was the time to make up for the failure she'd been her whole life: A foolish prude who believed herself to have self worth outside of men.

Finally, after an eternity of forcing, she managed to take the entire dildo into her throat, her eyes watering and her nose running. She couldn't see the men's faces, but she sensed their approval.

Encouraged by their reaction, Madison began to bob her head up and down, fucking her throat with the dildo, again and again and again, feeling the toy bash the back of her throat.

She felt her brain barely functional, focused only on the desire to skull fuck herself into oblivion. She barely knew what she was doing. But she also knew exactly what she was doing. And she knew that this was only step one in her plan.

As expected, soon she sensed that she could no longer hold back the rising sensation in her stomach. It was the yogurt she had for breakfast and it was about to return.

With a splutter, she pulled the dildo from her mouth, spewing the contents of her breakfast everywhere, onto the dildo, onto the floor, and onto her clothes.

The men laughed as Madison desperately tried to catch her breath, wiping the vomit from her lips.

Disgust and humiliation washed over her. It was beautiful. Quickly she tore off her clothes, exposing her tight body to the men. Just a few hours ago the idea of being exposed like this to strangers would have been terrifying. But those would have been the thoughts of some girl named Madison. Not a functional toy named Cunt Brain.

Now it was time for part two of her plan. She grabbed the dildo, using her vomit to coat its surface as lube, then positioned herself over it, lowering her ass onto the massive shaft.

The pain was unlike anything she had ever experienced, her anus stretching to its limits as the dildo penetrated her. Slowly she started to bounce on it, gradually speeding up until she was fucking it properly, knowing that the slightest slip up could be disaster.

Her already foggy vision began to fade from the corners. Everything was a blur. But she wouldn't stop bouncing.

She sensed the men closer to her then before and her body felt a jolt of lightning as she felt a hand impact her face. Then another. then another. It was amazing. It was heaven. She was accepted. She knew it.

Her last thought before she passed on was a certainty that from now on life would be perfect.
