As Natalia Kapretti woke up in the morning, she couldn't help but feel the need to use the bathroom. She hurried to the lavatory, her bladder already full to the brim. Once she was done with her business, she noticed that Kat, her slave, was still asleep on the floor next to her. An idea flashed through her mind, and she decided to take advantage of the situation.
Without hesitation, Natalia positioned herself over Kat's face, her pussy inches away from her slave's mouth. She let out a stream of warm urine, completely soaking Kat's face and hair. The smell of ammonia filled the room, and Kat moaned softly, realizing what was happening.
"Wake up, my little toilet," Natalia growled, smacking Kat's cheek softly. Kat groaned, unable to move as Natalia continued to pee on her face. "Do you like being my urinal, Kat?" she purred, her voice full of malice. "Because I certainly enjoy using you as such."
Kat whimpered, trying to squirm out from under Natalia. But it was no use; she was completely at her mistress's mercy. She could feel Natalia's hot piss dripping down her throat, filling her mouth and nose with the acrid taste of urine.
"That's it, Kat," Natalia said, leaning down to whisper in her ear. "Drink it all up. You belong to me now, and I'll do whatever I want with you – including using you as my personal toilet whenever I please."
Despite her hatred for what was happening, Kat found herself obeying her mistress's commands. She forced herself to swallow as much of Natalia's urine as she could, her body shivering with revulsion and excitement. When Natalia finally pulled away, Kat lay there, soaked and humiliated, but also aroused deep down inside.
"Now," Natalia said, smirking down at her helpless slave, "time for some rough loving." She grabbed a leather flogger from a table nearby and started to strike Kat's body with it – first on her breasts, then her stomach, before moving on to her thighs and buttocks.
Kat screamed out in pain and pleasure, her body jerking under the sting of the leather. She knew this was only the beginning of what Natalia had in store for her, but she also knew that she craved the pain and humiliation her mistress could dish out.
As the day wore on, Natalia continued to dominate and humiliate Kat, using her body in whatever way she pleased. She would tie her up, flog her, and even make her lick up her own piss and shit. Through it all, Kat remained loyal to her mistress, always obedient and always longing for more of her twisted affection.
Finally, when night fell, Natalia allowed Kat to collapse onto the floor, exhausted but satisfied. She watched as her slave curled up into a ball, trying to ignore the aches and pains that throbbed throughout her body. And even as she drifted off to sleep, Kat couldn't help but dream of the next time she would be used by her beloved mistress – this time as a human toilet once more.
