Even more

With the width of her plugged asshole approaching 4 feet, Samus was beginning to lose control of some of her faculties, but she could tell this wasn't enough, not even close to being enough.

"Ungh, AI can you, hoh hah mmn, oh yes further, WIDER. Can't you like help me stretch my butthole faster?" She said, through pants and groans, her over-stretched sphincter sending way too many signals to her bimbofied buttslut brain.

"As you wish," the AI said, before Samus felt the growth of the plug speeding up, her eyes rolling up into her skull, as the head inside her reached the size of a large mattress, with the neck becoming wide enough that if she didn't have the mass of silicone currently lodged inside of her gaping anus, you could have stood up on the rim of her impossibly stretched asscave, and held your arms out to the sides without touching them.

"Oh fuck yes! My asshole feels amazing!" Samus cried, her hands scrabbling backwards to find some purchase on the incredibly thin-stretched surface of her anus. Finding it, she hooked her fingers into the taut rim, pulling as hard as she could, creating a 6 inch gap between the flesh of her trembling anus and the mammoth buttplug stretching it out.

"Please AI, I need you to shove another toy up my butt," begged Samus, "it's still not wide enough!"

"You are insatiable," the AI said with mock surprise, only one person-sized buttplug in her ass wasn't enough? Well, the AI had plenty of toys to mess around with. One of which, the promiscuous buttslut had kindly provided herself.

Samus was busy creaming herself silly when a shadow covered her, car-sized belly bulge and gape included. She looked up and saw the familiar shape of her gunship hovering over her.

"I believe I may have found something that can finally satisfy you, Miss Aran," the AI said, "correct me if I'm wrong, but the dimensions of your ship are 20 meters(65.5 feet) long, 13 meters(42.5 feet) in width, and 5 meters(16 feet) in height?

"Oh fuck I don't care if it's a thousand feet wide, just fucking fill me with it already!" She said, gazing hungrily at the ship that brought her here, and now she would return the favor.

"Very well, try to relax your anus," the AI said before a second buttplug, identical to the one gaping her out, emerged from the ceiling, and crowded around her stuffed sphincter, trying to shove it's way inside.

Encountering failure, the plug(which was now the size of a monster truck) reared back, before slamming forward, faster than you could blink. The tip of the plug managed to lodge itself inside her overcrowded anus, and that was all it needed, as it preceded to barrel it's way into her room-sized colon, creating a bulge the size of a schoolbus in her stomach. With two plugs in her ass, able to work independently of one another, they began to pull themselves in opposite directions, one going right, the other left, stretching her entire body nearly in two, her legs getting brought along for the ride.

Finally, they had created enough space for her gunship, which charged up it's thrusters, before launching itself into her backdoor, the bulge it made went past her head for miles, stretching the skin of her torso out of the hanger into space.

Samus didn't say anything, she was probably dead lol
