The AI presents her with an enormous butt plug

"Wow this is like the perfect size!" Exclaimed Samus, as she admired the watermelon-sized butt plug.

She turned around, hooked her fingers into the rim of her fat, gaping anus, and pulled it open as far as she could(which was about 9 inches.) With her buttcave ready, she sat down on it, and her asshole was instantly spread over a foot wide, permanently stretching to accommodate the plug. Samus went cross-eyed at the insertion, and a huge bulge formed in her stomach. Once the whole thing was inside, her ass was left gaping open around the neck of the toy, unable to close anymore.
