As he stood over the bowed figure before him, upturned face eagerly waiting for his arrival, he felt a twinge of sadism stir within him. This was his plaything, his toy; she existed only to fulfill his desires. And one of those desires was for her to take his shit in her mouth.
He grinned wickedly and stepped closer, positioning his gargantuan erection at the edge of her parted lips. She moaned softly, trembling under his gaze as he leaned in closer. Slowly, almost teasingly, he pressed the tip of his cock against her lips, feeling her warm breath on his sensitive flesh.
And then he pushed.
The head of his penis forcefully penetrated her mouth, filling it to capacity in one swift motion. Her gag reflex kicked in, prompting a fresh round of moans that vibrated against his shaft. He looked down at her, watching as her eyes fluttered closed in ecstasy or pain - he wasn't sure which.
"Swallow my cum," he growled, pulling almost all the way out before slamming back into her throat. Her Adam's apple bobbed anxiously as she tried to breathe around his invading member, but she complied nonetheless. Her saliva mixed with his pre-cum, making it slick as he plunged deeper into her throat.
"That's it," he purred, lavishing her with soft, affectionate words that belied the cruel intent behind his actions. "Suck my dick like the filthy slave you are."
And she did. She sucked and licked and nibbled on his cock, drawing out every ounce of pleasure he could muster. He closed his eyes, lost in the sensation for a moment before snapping back to reality. This wasn't about pleasure; this was about control.
With a final thrust, he erupted into her willing mouth, filling it with his hot, thick cum. She worked her tongue around his shaft, lapping up every last drop of his essence before looking up at him with pleading eyes. He smiled coldly and stepped back, watching as she swallowed reflexively at the last moment.
"Well done," he said softly, reaching down to stroke her cheek fondly. "Now go clean yourself up. You're my plaything, not my toilet."
She nodded meekly and scurried away, leaving him alone once again with his twisted thoughts. Until next time, he mused darkly. Until next time...
