Yumiko stood in front of the bathroom mirror, admiring her reflection. Her long black hair cascaded down her back, framing her pale face with its delicate features. Her eyes were almond-shaped and slanted slightly upwards, giving her an exotic look. She smiled shyly at herself, feeling a bit nervous but also excited about what she was about to do.
She reached into her school bag and pulled out her phone, then turned on the camera and positioned it on the sink beside her. The yellow lock icon on the screen indicated that no one else could access the video. With one last deep breath, she slipped off her loose-fitting uniform skirt and stepped out of it.
She was wearing a plain white cotton undergarment that hugged her curvy hips and sat low on her waist. It was one of those japanese schools underwear that didn't conceal much, leaving her nether regions exposed and vulnerable. She took a step forward and straddled the white porcelain bowl, positioning her bottom over it.
Her heart was racing as she lowered herself slowly onto the cold surface of the toilet seat. She could feel the warmth spreading between her legs, and instinctively she spread them wider, opening herself up even more. She gasped softly as she pushed the tip of her finger against her clit, teasing herself while she watched herself on the screen.
Yumiko leaned forward, her breasts nearly touching the cool surface of the mirror as she watched herself squat down. Her firm round buttocks hovered just above the bowl, tempting fate as she prepared to release a deluge of filth from her bowels. With a hesitant look in her eyes, she pushed off with her feet and sent a large, warm turd plummeting into the waiting water below.
The sight and sound of it filling the bowl made her shudder with pleasure, and she closed her eyes, letting out a moan. She felt so dirty but so incredibly aroused at the same time. With determined movements, she pushed herself off again, forcing another log of shit out of her tight little asshole. It splashed against the walls of the bowl, mixing with the first one to form a vile, steaming mess.
Yumiko couldn't believe how good it felt, knowing that she was making such a disgusting spectacle for the camera. She reached down between her legs, rubbing her swollen clit as she sat there, pooping into the toilet. Her pelvis rocked back and forth, and she could hear her own moans echoing off the tiled walls.
Finally, after what seemed like an eternity, she felt the last of it slide out of her ass, and she let out a long sigh of relief. She couldn't believe she had just filmed herself taking a dump for so long. She looked down at the soiled mess in the toilet, feeling a mixture of pride and revulsion.
With shaking hands, she flushed the toilet, sending the disgusting mass of feces and urine down the drain. She wiped her hands on a nearby towel and took a step back, surveying the scene. Her underwear was soaked through with sweat and piss, and there were streaks of shit on her thighs. She couldn't wait to watch the video later, to relive every messy, filthy detail.
