Siya, a stunning plus-sized diva, reclined luxuriously on her plush sofa. Her eyes scanned the room as she awaited the appearance of her new toy - her slave. Dressed in nothing but her favorite lace lingerie, she exuded an aura of potent sexuality and dominance.
Finally, there was a knock on the door. She smiled seductively and called out for him to enter. The door opened, revealing a nervous yet eager young man who bowed low before his mistress. Siya's tone was both commanding and soothing as she addressed him, "Come here, slave. Fetch the feeding tube."
The slave hurriedly complied, grabbing the custom-made feeding tube from a nearby table. It was a long, rubbery hose with a bulbous end designed for inserting into an orifice - in this case, the girl's gaping asshole. He knelt before Siya, presenting the tube to her.
Without further prompting, Siya sat up straight and pushed her panties to the side. Spreading her enormous cheeks, she displayed her tight, pink anus to the eager man. "Open your mouth, slave," she commanded softly.
Obligingly, the man parted his lips and tilted his head back. He watched in awe as the bulb of the feeding tube disappeared into Siya's rectum, burrowing deeper until it reached her sigmoid colon. A look of pure bliss crossed her face as she began to poop, filling the tube with her warm, supple feces.
With a flourish, she pulled the feeding tube from her asshole and detached the bulb, revealing a globby, semi-solid mass of shit. She held it up fondly before lowering it slowly towards the slave's waiting mouth. As it approached, he could already smell the tangy aroma of her feces, his mouth watering with anticipation.
Finally, the shit touched his lips. His eyes widened as he felt the slippery warmth of Siya's waste on his skin. His tongue snaked out to taste it, and he moaned in pleasure as the thick, viscous sludge coated his taste buds. In a slow, sensual motion, he began to suck on the feeding tube, drawing more of Siya's feces into his mouth.
As he relished the taste of her excrement, Siya reached back and began to stroke her enormous, glistening buttocks. She groaned softly, feeling the build-up of pressure in her bowels. With a satisfied sigh, she released another torrent of feces into the feeding tube, forcing it back down the slave's throat.
For several minutes, she enjoyed this intimate exchange of fluids, her body trembling with pleasure as the slave worshiped her. When she finally pulled away, her cheeks were smeared with his saliva, his face shiny with her shit. "Now, on your back," she commanded, pointing towards the plush carpet.
Obediently, the slave lay down on the floor. Siya climbed atop him, her weight pressing down on him gently. She straddled his face, her thick thighs nearly touching his ears. Lowering herself onto his mouth, she slowly began to grind her pelvis, teasing him with the proximity of her anal opening.
"Suck on my asshole, slave," she purred, her voice dripping with honey. "Taste what only I can give you."
With a moan of desire, the slave complied. Siya's buttocks were soft and warm against his lips, inviting him to explore the moist crevasse between them. He licked and nibbled, drawing more of her feces into his mouth as he was meant to.
They shared an intimate moment, each lost in their own desires and pleasures. As Siya reached her climax, her body shuddered violently, and she let out a loud moan. A thick, turdlike glob of shit squirted from her asshole, splattering against the slave's face and chest.
Grinning, she leaned down to whisper in his ear, "Now, on all fours."
The slave complied, presenting his exposed, vulnerable ass to his mistress. Siya chuckled darkly, walking behind him. She spanked his plump, round cheeks, leaving fiery red handprints against his pale skin. "You're so beautiful like this," she mused, reaching between his legs to stroke his growing erection.
With one swift motion, she pushed the feeding tube deep into his anus. "This is what you want, isn't it?" she taunted him, her voice deliciously cruel. "You want my shit inside you."
Satisfied with his response, Siya began to fill him up. She took her time, savoring the feel of his tight sphincter tightening around the tube. She filled him with several different types of feces, each one more explicit than the last.
As she finished, she pulled the feeding tube out, leaving a trail of filth behind. The slave lay there, trembling, his ass glistening with her excrement. He knew that this was only the beginning of his training under Siya, the SSSBW Queen. But for now, he was content to bask in her glory and await her next command.
