As the plump SSBBW queen slid her luscious behind onto the royal throne, she knew exactly what she wanted to do. Siya had been feeling a bit gassy after her extravagant feast, but she figured she'd take advantage of it anyway. She couldn't resist the idea of dominating her pathetic human toilet while she suffered through her intestinal discomfort.
Sitting on her subject's face, Siya closed her eyes and savored the feel of his warm breath circulating around her ass crack. She allowed herself to enjoy the slow buildup of pressure inside her ass, relishing in the complete and utter control she had over him. She could feel his desperate attempts to breathe, his tongue flicking out of the corner of his mouth as he struggled not to pass out from the lack of air.
Feeling a slight twinge in her gut, Siya opened one eye and glanced down at the pathetic creature beneath her. His face was already bright red, and she could see the tears welling up in his eyes. She smiled cruelly, rolling her huge belly at him playfully before leaning over and whispering in his ear. "This is what it means to be a human toilet," she hissed, "so just be grateful I allowed you to keep your life while you serve me."
As the urge to defecate grew stronger, the queen felt a rush of pleasure course through her veins. She wanted nothing more than to push her massive turd straight into his eager mouth, but she knew she couldn't risk it just yet. Instead, she wrapped her meaty thighs around his head, squeezing his face and trapping his tongue between her plump cheeks. She moaned loudly, grinding against his face as she waited for her sphincter to relax enough to release her "gift."
Finally, the moment arrived. With a mighty heave, Siya forced her bowels to open, releasing an enormous log of shit directly into the waiting maw of her human toilet. He let out a muffled gasp as the first wave of filth hit him, his eyes watering as he tried to process the overwhelming stench emanating from her bountiful behind.
As the queen savored the feeling of her toilet's struggles against the massive turd in his mouth, she felt a sudden and unexpected stirring in her bladder. She giggled, knowing exactly what she had to do. "You're such a disgusting mess already," she chuckled, "Why waste all that perfectly good pee?"
Directing her unwilling slave to crawl to the nearby toilet chair, Siya allowed him a brief respite from her enormous girth. With a wicked grin, she watched as he scurried over, his face beet red and covered in her shit. "Congratulations, toilet boy," she purred, her voice dripping with sarcasm. "You've done your duty. Now it's time to make sure every last drop of my piss ends up in that filthy mouth of yours."
Never breaking character, even as she relished the flavor of her own piss trickling down her throat, the queen gave her victim a stern nod. "That's a good toilet," she cooed, running her tongue around the edge of his mouth playfully before standing up and wiping her ass with one of his shirts. "I think I'll keep you around for a while longer; I can already tell you're going to fit in perfectly here at the palace."
