Maxine took a deep breath as she lowered herself onto Leonard's smiling face. Her bulging red eyes followed the movements of her enormous ass cheeks, tracing the contours of her body that squeezed the air out of Leonard's lungs. What am I doing? she thought, but the sound and sight of her own intestines sloshing against his tongue made her lose herself in the dirty pleasure.
Her full weight came down onto his shoulders and neck, pushing him deeper into the filth. Leonard's eyes widened in horror, but he could barely see through the sea of pink flesh above him. He gagged and choked on a mix of vomit and feces as Maxine began to grind her hips back and forth in a slow rhythm that was both agonizingly slow and unbearably arousing.
"Are... you enjoying this, Toilet Guy?" she purred, her hot breath hitting his gagged lips. "Because I have to say, I am. It's kind of liberating knowing that I can use someone like you simply for my pleasure."
Leonard wanted to scream and beg for mercy, but all that came out was a wet, incoherent groan. He could feel himself blacking out, his ability to breathe slowly choking that very thought out of his head. The sensation of his airway being cut off by Maxine's enormous ass only made his cock harder than ever, and he prayed for her to keep going even as his vision began to blur.
"Oh, don't worry," Maxine chuckled, running a fingernail along Leonard's lower lip. "I'm not going to kill you just yet. After all, what fun would that be?"
She rocked her hips harder, grinding against his tongue and lips, her pussy now completely soaked in a mixture of her own juices and human waste. Leonard felt like he was being suffocated, but at the same time, he had never been more aroused in his life.
As he began to lose consciousness, he could feel Maxine's orgasm rippling through her body. She moaned loudly and her hips shook violently, pushing Leonard deeper into the abyss of filth and loss. A torrent of hot cum sprayed out of her pussy, hitting him in the face and chest, mixed with the revolting smell of shit and piss.
Leonard could no longer see or feel anything. He was entirely consumed by the sensations of Maxine's body, the taste of his own vomit and her cum in his mouth, and the overwhelming stench of human excrement. As he sank into darkness, he could only hope that this was the last thing he'd ever taste.
