As the sun began to set, the bustling city streets gradually emptied, leaving behind only those who found themselves out late or simply didn't have the luxury of going home. Among them was a petite and beautiful schoolgirl, her uniform perfectly pressed and her hair tied up in two neat pigtails. She walked down the alleyway, her eyes darting between shadows as she crossed her fingers and tried to make it to the nearest public restroom without incident.
Her stomach was in knots - she'd had a heavy lunch and the cafeteria food hadn't agreed with her. All day she'd been shuffling from one end of class to the other, praying that the pressure in her gut would subside. But now that she was outside, the need was overpowering. She felt a warm trickle running down her inner thigh and forced herself to hurry up before things got any worse.

She could feel it seeping into her panties, spreading heat and dampness between her legs, and she knew that there was no going back now.
Finally, after what seemed like an eternity, the spasms subsided, and she managed to take a moment to catch her breath. She reached down between her legs and tugged gently at the sodden crotch of her uniform, groaning in disgust as she felt how wet and sticky it was. There was no way she could keep going like this – she needed to find some way to clean herself up.
Just then, she heard a metallic clanking noise from behind her, and her eyes widened in terror as she realized what it was. There, standing in the corner, was a human-sized platform attached to a tank of shimmering liquid. Oh no, she thought, my worst nightmare is coming true...
