Natsuki had promised herself that she wouldn't ever shit in a public toilet again. The smell of the stalls, the grime on the seats, the sounds of people coming and going; it all sent chills down her spine. Yet here she was, ballooning her poor little asshole with a day's worth of dark, heavy feces.
She squirmed uncomfortably in her chair at work, her eyes watery from the effort it took not to double over and just give in to the intense pressure building up inside her. Sweat trickled down her back as she tried desperately to hold onto her dignity.
Just when she thought she couldn't take it anymore, she felt the dam about to break. She took a deep breath and pushed as hard as she could against her full bowels, biting her lip to keep from crying out. Her asshole stretched and strained, the stench rising up around her like a cloud.
As the first thick log of shit slipped out of her tight little starfish, Natsuki cringed in mixed horror and relief. It was ugly, it was dirty, but it was finally out. She breathed a sigh of relief and continued pushing, feeling the mass of her insides slipping free from her poor abused asshole.
The smell of her shit was overwhelming, even to her. It was a deep, fishy scent, warm and revolting all at the same time. She could feel her nostrils flaring as she pushed and pushed, filling the dingy little stall with the rancid smell of her garbage.
Finally, after what felt like an eternity, she was able to release the huge pile of feces that had been weighing her down. It was a beautiful, disgusting sight; long, sausage-like turds stacked horizontally in a low pile on the toilet seat. She couldn't help but admire her own handiwork, even as she struggled not to gag on the overpowering scent.
With a trembling hand, Natsuki lifted the toilet seat and flushed the mess away, watching in morbid fascination as it swirled down the drain. She took a moment to catch her breath, her heart still racing from the sheer relief of finally emptying herself.
As she stepped out of the stall, she couldn't help but wonder how many more times she would find herself in this miserable situation. Would she ever learn to control her body? Or would she forever be at the mercy of her own disgusting impulses? Only time would tell.
