Kimiko woke up in the middle of the night, feeling a heavy pressure in her bowels. She was alone in her small, cozy bedroom, nestled in her favorite secret spot under her unicorn-printed sheets. Her phone was already on the nightstand, so she reached out and unlocked it, sliding into the camera app. She squirmed a little in her bed, trying to find a comfortable position as the pressure in her guts grew stronger.
She lifted up her fluffy nightgown, revealing her smooth, milky-white behind. It was slightly chubby, with adorable little dimples on either side of her anus. She adjusted the camera angle, positioning it to capture her whole body from the waist down. The phone's screen glowed softly, illuminating her face with a warm, ethereal light as she prepared to film herself pooping.
Kimiko closed her eyes, taking several deep breaths to calm her nerves. Her stomach rumbled softly, and she felt a warm stream of liquid flowing out of her winking asshole. It was just a small trickle at first, but gradually it grew into a steady stream as her body gave in to the urge. She couldn't help but let out a soft moan of pleasure as she felt the warm sensation spreading throughout her abdomen.
The rhythmic squelching sounds of her feces leaving her body filled the quiet room. Kimiko's thighs trembled slightly as she pushed harder, grunting with effort. Finally, after what felt like an eternity, she let out a long, satisfied sigh. A massive log of shit plopped onto the toilet seat with a loud splat, followed by a rush of urine as she finished peeing.
Panting heavily, Kimiko lowered her nightgown and leaned back against her pillows, exhaling deeply. The weight on her chest eased as she watched the video playback on her phone screen. She smiled proudly at the image of herself, covered in sweat and grime, but victorious. Kimiko titled the video "All Girls Poop (Self-Filmed) - Kimiko's Relief," feeling a sense of accomplishment wash over her. She hit the upload button, eagerly anticipating the comments and reactions from her followers.
