As the day drew to a close, Lily felt an intense sexual arousal inside her. Her mind was clouded with lustful thoughts and her body was aching for release. She hurried to the bathroom, feeling a strong urge to defecate. She looked down at her clean white panties, eagerly anticipating the dark stains that were about to mar them.
In the privacy of the bathroom, Lily reached into her panties, spreading her cheeks apart to expose her bare anus. The cool air against her skin only served to heighten her desire. She breathed deeply, trying to control the sensation as her asshole tightened in anticipation.
With a loud grunt, Lily pushed out the massive turd that had been building up inside her. It was enormous, filling her panties with hot, smelly shit. She couldn't believe the amount of shit that had come out of her. She felt a rush of pleasure that was almost indescribable.
Lily slid her panties down to her ankles, revealing the monstrous turd inside them. She used her hand to spread the shit across her panties, covering her pussy and ass in a thick layer. The feeling of the cold air hitting her exposed ass and pussy sent shivers of excitement down her spine.
Her fingers found their way to her clit, which was rock hard and aching for attention. She started rubbing it gently at first, but soon she was furiously jerking off, her slimy fingers coated in a mixture of her own juices and shit. The dirty girl moaned loudly as she approached her climax.
With a final push, Lily's body convulsed and she came hard, shooting thick strands of cum all over her hands and the shit-covered panties. She let out a long, satisfied moan before finally pulling out the shitty panties and flushing them down the toilet. She leaned against the bathroom wall, breathing heavily, her body still tingling from the intense orgasm.
Lily looked down at her messy fingers, a devilish smile forming on her lips. She couldn't wait to get home, slip back into her shit-covered panties, and rub herself raw all over again. And the next day, and the one after that. She loved being a shitting, scat girl in black.
