Natalia Kapretti, a dominant woman who relished in controlling the boundaries of pleasure and humiliation for her slave, enjoyed fisting and shitting on her submissive partner. She found pleasure in pushing the limits of their taboos, often forcing her slave to assist in the acts which he simultaneously loved and hated.
One day, as Natalia luxuriated in a warm bathtub of her own shit, she observed her slave positioned on the ground, his mouth open and ready for her to fill it with her excrement. A determined look crossed her face as she picked up a fresh turd and smashed it into his mouth, relishing in the sight of his throat struggling to contain the repulsive mass of filth.
With a commanding voice, she ordered the slave to move over so she could clean herself properly; his body was leaking a viscous mixture of her feces and semen. When he failed to respond quickly enough, she swung her heavy steel cage around, slamming it against his ribs and forcing him into submission.
As he lay on the ground, wincing in pain, Natalia began her meticulous cleansing process. She used a large, industrial-sized syringe to inject warm water into his rectum; the force of the stream sent waves of searing heat through his body. Next, she applied a copious amount of lubricant, ensuring that every inch of his channel was well-oiled for her upcoming invasion.
Finally, it was time for the main event. Natalia positioned herself above her slave's prostate-filled behind and, without warning, forced the head of her enormous fist into his defenseless anus. She felt the warmth of his body envelop her hand as she slowly pushed further and further inside, inch by inch until her fist had completely disappeared within her slave's body.
Moaning in pleasure, Natalia began to thrust her fist in and out of her helpless victim's body, each forward thrust pushing further than the last. Her stomach churned with anticipation as she waiting for the climax of both their needs: for her, the release of absolute control over someone else's destiny, and for him, the painfully intense orgasm he always experienced when used to its fullest potential.
Their shared moments of pleasure were punctuated by moments of extreme discomfort - for Natalia, the grimacing face of her slave as she relentlessly pistoned her fist in and out of his body; for the slave, the searing pain that coursed through his intestines with every powerful thrust. But neither one could resist the siren's call of their forbidden desires.
As Natalia felt her own climax approaching, she withdrew her fist and grabbed the slave's head, forcing him to open his mouth wide. With an audible gulp, she thrust the tip of her fist onto his tongue, smearing it with a mixture of her own fluids and the remnants of her feces.
"Swallow it all," she hissed, cold eyes boring into his. And swallow he did, every last drop of their union. As the slave lay there, panting heavily from the exertion and the pain, Natalia looked down at him, a look of triumph flashing across her face. She had claimed him completely, both body and soul - and now she would keep him forevermore.
