Siya, the stunning SSBBW Mistress with a cruel streak, was delighted with her new toilet slave. He had shown incredible devotion by eating all the disgusting creatures she could find beneath the waves, even though he was already stuffed to the brim with her previous meals. His stomach must have been a bottomless pit!
As she strutted into her lavish bathroom, the aroma of sewage assaulted her nostrils. She couldn't help but to revel in the repulsiveness of it all. Siya sniffed the air like a hound tracking its prey, savoring the lingering scent of her slave's excrement-filled belly. A devilish grin spread across her plump lips as she thought about how much fun she was going to have with him next.
Toggling between vanity mirrors, Siya admired her naked body - the perfect embodiment of power and perversion. Her rolls of fat jiggled subtly as she moved, and the sight of her enormous breasts, ample thighs, and plushy buttocks was enough to make any man kneel before her in submission.
She took a moment to select an outfit that would make her slave squirm with anticipation - a black latex corset that cinched her waist tightly, accentuating her voluptuous lead-covered curves, and a pair of stiletto heels that added inches to her already towering figure. As Siya slipped into the corset, the material groaned under the weight of her bulk, making her feel even more in control.
Stepping out of the bathroom, Siya's eyes met with her slaves terrified gaze. He trembled beneath her gaze, knowing what was coming next. Slowly, she unzipped her skirt, revealing a tempting glimpse of her black thong which she had purposely worn without any panties beneath.
"Good boy," she purred, striding towards him. Her ass swayed seductively as she walked, and the sound of her high heels echoed through the room. Up close, the smell of excrement wafting off him was almost overwhelming, but instead of revulsion, Siya felt a twisted thrill.
"But you know what?" she continued, leaning in close enough for him to feel her hot breath on his cheek. "You've been such a good toilet slave that I think you deserve a treat." She winked, and then turned around, presenting her plump rump to him.
"Eat it," she commanded, her voice a low growl. "Eat every last drop of my shit, and make sure you swallow it all. If you can handle that, maybe I'll let you lick my asshole clean too."
The trembling slave hesitated for a moment before lowering his head reverently towards her ass. His tongue snaked out, and he tentatively touched the creamy white substance dribbling from her anus. It tasted as foul as it smelled, but he could hardly refuse his Mistress when she was in such a playful mood.
As he began to lick and suck on her rump, Siya let out a contented moan. She placed a hand on his head, forcing him to take deeper, more passionate kisses of her ass. The feeling of his tongue swirling around her inner thighs was almost akin to pleasure, and she secretly enjoyed the way he seemed to struggle with the repulsive task she had set him.
"Better not get any off on my expensive underwear," she warned him with a smirk. Her voice was stern, yet playful, and it sent shivers down the slave's spine.
After what seemed like an eternity, he finally managed to clean her out. Siya grabbed him by the collar and yanked him towards her so roughly that his teeth clicked together. "Good boy," she cooed, her breath hot against his neck. "Now, it's time for me to return the favor."
Reaching down between his legs, Siya grabbed hold of his cock, which was already rock-hard with anticipation. "You've been such a good little shit-eater," she purred, "I'm going to let you fuck me into next week."
Without further ado, she lowered herself onto his cock, engulfing him in one swift move. The slave groaned as he felt the warmth of her ass wrapping around him, and he began to pump into her hungrily. Siya let out a long, low moan of satisfaction as he filled her up, and then she leaned back against the wall, using her immense weight to take control of their encounter.
As they fucked, the room filled with the sounds of flesh slapping against flesh and the disgusting aroma of excrement and sweat. But to Siya, it was the most exquisite torture she had ever experienced. She knew that she was pushing her slave to his limits, and that he was only doing this because he had no choice - but she couldn't help but revel in his humiliation.
Finally, with a loud cry of pleasure, Siya came, shuddering as she felt the force of her orgasm ripple through her like a tidal wave. Her slave followed suit moments later, spewing his hot seed deep inside her ass. Collapsing onto him, Siya panted heavily, her chest heaving up and down.
"That," she whispered softly, nuzzling her cheek against his, "was truly scrumptious."
