The Digestive Solidification Upgrade

(As stated in the previous chapter, this path is full of gross content involving hard scat, so consider this your final, final warning.)

"As you likely have surmised based upon the nature of the previously discussed Gas Upgrade, the other Digestive Upgrades will alter the way you rid yourself of waste. These have not been extensively tested and there is, relative to other upgrades, a higher chance of malfunction though that is still quite a rare possibility." The AI spoke in an informed tone, as Samus nodded in approval.

"I think I have a pretty good idea about what this might be, but can you tell me more about this 'Digestive Solidification Upgrade'?" Samus asked, her curiosity over-powering all other emotions, including both disgust and deeply buried arousal.

"Certainly, Ms. Aran, the Digestive Solidification, henceforth referred to as the 'Scat Upgrade' is the progenitor chip of the Gas Upgrade, rather than turning all waste into flatulence, it turns it into solids. You will no longer urinate nor pass gas and instead, these will be replaced with defecation, and you as a result you will need to poo with far more frequency. However, you will have a far stronger digestive system, and you will have far more powerful anal muscles. Assuming all is well with the chip, you will be in full control of your digestive system, anal muscles, and the nature of your defecation, meaning you will be able to decide the nature of your waste, whether you prefer it to be harder or more fluid. To summarise, you will have full control over your stomach and solid waste, at the cost of more frequent toilet breaks. Oh, and I should mention, defecation will feel far more pleasurable." Despite the long-winded explanation of the chip, Samus absorbed it all, weighing the pros and cons of it in her head.

After a few moments of silent consideration, Samus decided to screw it and asked the AI to give her the chip. After all, if she didn't want it, she could just uninstall it, right?

"Will the... poop itself change at all?" Samus asked.

"I mentioned previously that you control the facets of your waste, but without specific sub-upgrades for the chip, your feces will not have any special properties."

After taking the chip from its receptacle, the bounty hunter plugged the chip into a slot on her spine. For a few short moments, there was nothing-

Then an incredibly pleasurable sensation ran through her bowels like her stomach was having an orgasm. As she was clutching her stomach in euphoria, the area of her Zero Suit where her asshole was, said hole puffing out slightly. The orgasmic feeling had descended into a tingle, nesting itself just inside her asshole. For a moment it lingered before vanishing, replaced with a pressure. Samus needed to take a big shit, and the clenching of her now enhanced anal muscles barely slowed the stampede raging in her insides.

"Nnnnnngh!" Samus grunted, trying to hold in her shit. Though, before long she failed and a massive thick turd, hard as stone and longer than her arm, came crawling out like a brown snake. All the while it pushed out of her, Samus moaned in delight, nearly orgasming from the pleasure of shitting on the once clean floor.

After a minute or so of basking in the pleasure, her new chip affords her, before the AI spoke up.

"I will deploy some robots to clean your waste. Feel free to defecate anywhere outside of the upgraded room, please. There is a cafeteria for your convenience down the hall, and just beyond that a bathroom. If you want to apply for sub-upgrades, please go through the door to the right."

The sheer pleasure of the act of shitting was so great, the bounty hunter couldn't bring herself to remove the upgrade. Though she had some choices, should she further upgrade her digestive system, or apply other upgrades in conjunction with her newly tested one? She could just stick with her scat upgrade, and go test the limits of it. Or maybe she's had enough and just wants to get back to her job, though now lacking stomach stability.
