Here's one of my more recent stories I did as a request on Tumblr.

Samus Pantypoop

‘Hindsight is 20/20’, Samus thought as she struggled to make it back to her ship. Perhaps she should have landed closer to her objective, or perhaps she should have taken care of this issue earlier. There was nothing she could do now but hurry. Even as she boarded her ship, got free of her Power Suit, and was so close, Samus knew it was too late.

Her stomach was tight, full, uneasy. Normally, her muscles were strong enough to keep this sort of thing at bay, but not today. As Samus made her way to the bathroom aboard her ship, she felt it crowning. Her anus was spreading under the sheer weight of it all. It slowly inched its way out as she struggled to free herself of her Zero Suit. She was so close, finally getting a grasp of the neckline to begin removing it, but that's when a sudden surge hit her.

No longer was she in the clear as that firm, yet sticky log began to freely leave her body. Samus gasped in surprise, leaning against a nearby wall as her muscles disobeyed her and pushed everything out of her. She knew just to let it happen, there was no stopping that thick mess as it spread her asshole wide.

It curved as it hit her Zero Suit, slowly coiling inside her outfit and spreading outward as she dumped more into it. Faint pops were caught by Samus’ ears as air escaped her hot, melted chocolate. The texture was odd, slowly covering more of her firm butt, but the warmth was oddly pleasant. A sense of relief, and a bit of pleasure, came over her, even as her suit began to bulge and sag from the raw weight of it all.

Soon she found herself pushing, wanting to empty her colon into her distended Zero Suit. She groaned, forcing more mess out of her, quivering as the incredible heat radiated out of her now soiled suit. Whenever Samus thought it was over, another log slithered its way out. Part of her wished she could continue this for longer, to experience such strange pleasure for more than a few fleeting minutes, but even her body couldn't hold that much in. The last log came rushing out with only a slight push, six inches in less than a second.

Samus moaned loudly. She could feel her pile of mess in her suit swell, the heat spread, her colon finally relax, and her backdoor gape from such a long, sizable bowel movement. Her hand slowly moved its way to her ass, fingers touching the outside of it. She could feel the weight, the sheer volume and heat, in a new way. There had to be at least 2 to 3 pounds of perfectly firm, moist poop inside her suit. It ballooned outwards at least 4 inches; a massive bulge in her otherwise skin-tight suit.

It was more pleasurable than she'd ever have thought. Her mind wandered as her hand squeezed and pressed up against her soiled suit. Perhaps she'd do it again, maybe even try something else. Being a bounty hunter was a lonely life, she loved finding enjoyment wherever she could and this required further experimentation.
