As Satsuki prepared for her day, she felt a slight pressure in her bowels. She ignored it, hoping it would go away, but as the morning went on, the discomfort only grew. Finally, she had to stop and address the issue head-on.
She made her way to the bathroom, her rounded ass swaying gently in her skirt. After locking the door behind her, she undid her loose-fitting blouse and let it fall to the floor, revealing a lacy black bra that barely contained her ample breasts. Next came her skirt, which pooled at her feet, leaving her standing there in just her black panties.
Satsuki took a deep breath and lifted the toilet seat, securing it in place with a plastic lid for good measure. She lowered herself onto the cold porcelain, shivering slightly as she adjusted her weight on the toilet seat. The pressure in her bowels became more insistent, and before long she felt the familiar sensation of a large dump building up inside her.
She breathed deeply, closing her eyes as she concentrated on the task at hand. A moment later, a hot gush of pungent diarrhea erupted from between her legs, splattering against the inside of the toilet bowl. It was a thick, runny mess that smelled awful, but she couldn't help but feel a twisted sense of satisfaction as she watched it flow.
Satsuki continued to relieve herself, letting out small moans of pleasure as she emptied her bowels. Soon, the toilet was filled with her fecal matter, and she felt an intense sense of relief wash over her. She sat there for a moment, catching her breath, before reaching down to clean herself with toilet paper.
Feeling a bit daring, she remembered the container she had seen online that was designed for exactly this purpose. It looked like a glass jar with a smooth, wide mouth that fit perfectly over the toilet bowl. She had been curious about it for a while but had never mustered the courage to try using it. Today, however, she decided to take the plunge (pun intended).
Satsuki carefully lifted the lid off the toilet bowl and positioned the wide-mouthed jar directly beneath it. As the last of her waste splashed into the toilet bowl, she released the plunger, watching in fascination as the thick, brown sludge rose inside the transparent container.
She turned off the water and gazed at her creation for a moment, marveling at the fact that she had created such a massive, messy poop all by herself. A sense of pride and accomplishment washed over her, and she couldn't help but grin as she carefully screwed the lid back onto the jar.
With a final glance at her handiwork, Satsuki stood up, smoothing her skirt down over her ass and adjusting her bra. She felt both dirty and thrilled, like she had just experienced something taboo and exciting. As she made her way back to her room to clean up, she couldn't help but wonder what other kinks she might discover lurking within herself.
