She wakes up the next morning

Samus awoke on the floor of the station and groaned, her body still sore from the previous day's events. Although awake she had yet to open her eyes as she mentally pinged her suit for a status update. She read her internal HUD.

**Nanobot Storage: %5 - Replenishment in progress. Estimated Time: 12 hours.**

'well that's a relief. At least I get a bit of a break's she thought to herself.

She shifted her mental focus onto the next line.

**Capacity Upgrade: 20% Complete. Awaiting Resources to continue**

Her tired mind was sluggish to register what that meant and in an instant she remembered where she was and what had happened. Her eyes shot open and she rolled over and sat on her bum on the ground as she looked around the room.

'Right! I'm in the space station. I got the capacity Upgrade. I'm on the ground. That would explain the throbbing in my ass.'

Her eyes roamed the room for more details and saw a puddle of spit where she had been resting her head while she slept. Now she was awake Samus slowly got to her knees and stood up on shaky legs. Something felt...different. Strange...

A previously ignore mirror was imbedded in the far wall and she walked over to get a look at herself. She still had the same long, platinum blonde hair, a cute face and blue eyes which matched her blue skin tight suit. The suit hugged her body on every curve and she admired the way it made her D cup tits look as perky as ever, even going so far as to wrap around her nipples allowing them to be clearly seen as they constantly jutted out.

She followed the curve of her belly to her juicy hips and it was there that she noticed something different. They were definitely a little wider. Where she had once had a cute bum, what most would call curvy but definitely not large, was a the ass of a goddess. She ran her hands along its curve and she felt the jiggle of it and realised her figure was now a perfect hour glass. Her thigh gap had increased, still showing off her slender legs and as she spun to see it from a new angle her mouth fell open. When she spun around to see it from behind she saw that her suit wasn't as complete as it used to be. Where it has once covered her entire body from her neck down she now saw a large hole all around where her ass was. The gap in the suit however was not what has made her mouth drop open; It was her asshole. Where yesterday she had had a tight pink hole next to her little pussy, she had a massive, gaping asshole. Her hips were so wide that her ass cheeks were constantly spread and between them she could see a wet looking, completely destroyed asshole. Her rim wasn't even round or even but sagging a good inch from where it should be. It was clearly wet and puffy and as she watched she saw a large glob of thick liquid drip from her hole and land wetly on the ground with a splat.

Almost too hesitant to try, she slowly brought her hand around and tentatively stroked a finger along the ruined rim of her asshole eliciting a gasp followed by a moan as she used more pressure. The stimulation seemed to trigger something in her body because she felt a distinct feeling of emptyness that ran from her asshole rim to her completely stretched out colon, deep through her intestines until, to her shock and arousal, she felt it end just as it entered her throat.

'that....this can't be possible. How deep is my asshole?' to her suprise she heard the external speakers of the Stations AI answer her mental question,

"Exactly 1.21meters deep" it answered robotically.

"Wait what?" Samus said on shock. "What is that in American?"

The AI did it's best simulation of a sigh.

"Uugh. About 4ft. Human"

"But that's impossible. I'm only 5ft 2. How can my asshole be that deep?"

The AI needed a moment to compute it's response and the waiting made Samus nervous.

"The upgrade has modified most of your internal organs. Your insides are now 90% gaping asshole, with your throat being directory connected to the same tube. Your digestive tract has been improved so you no longer posess or require a stomach. Your throat ends approximately at your colar bone before opening up into your improved anal cavity."

Samus needed a moment to take it all in. She was now 90% asshole? She swallowed at the implications and strangely she felt the spit work it's way down her throat before she felt her knees almost buckle as her asshole was stimulated by her throat muscles. "fucking hell" she panted. "All I did was swallow."

"Ah yes. As you may have suspected, your sensitivity has been increased by 10fold in your throat and by 30 in your asshole. We advise against getting addicted to stimulation though experiment subjects have so far not been able to avoid it. Perhaps your military training will assist your will power in this."

Standing up straighter and trying not to focus on the delicious feeling of thick globs of lube sliding down her insides she asked "ok so my ass is completely ruined" this was punctuated by squishy fart of lube causing her eyes to roll as her assholes loose rim flopped open and closed. Samus regained her composure to continue, "how is the capacity Upgrade only 20% done? My asshole can't get any bigger"

The AI answered quickly. "Experiments disagree with that statement

.." Samus' eyes widened, "...but to answer your question, the Capacity Upgrade has specified 5 more areas it can increase the capacity of."

Samus was confused. She assumed maybe her pussy and maybe her mouth but where else could the program be thinking of?

"Umm ok computer.... Where are these areas?"

There was a machine-like humming noise and after a few seconds, "Connection cannot be established with nanobots" Samus frowned.

"What?"

"Connection to Upgrade Chip lost. Cannot establish connection."

"So what you're telling me is that you don't know what these other areas are? You have no idea what is going to happen to me? What is it going to increase the capacity of?"

If Samus could see into the mind of the AI she would've seen it smiling.

"I can't do that, Samus"

"You can't or you won't?"

The AI remained silent. After a few minutes Samus broke the silence. "Well fine. I'm heading back to my ship. If you ever see me again make sure you have better control of your upgrades."

With that she left the room and started walking down the hall, her puffy hole sliding along itself with each step and making her edge.
