Once upon a time in a faraway land, there was a woman named Mistress Alex. She was known for her domineering personality and her love for excreting. Alex had a peculiar fetish; she loved to see her slaves become shit addicts. Her favorite slave, whom she called Suck, had an especially impressive ass that Alex enjoyed filling with her heavy shits on a daily basis.
One day, Alex summoned Suck to her luxurious chambers. She was sitting on her royal golden throne, wearing nothing but a revealing satin robe that highlighted her voluptuous body. Suck kneeled before her, eyes fixated on his mistress's perfect ass.
"Today," Alex began, her voice filled with lustful anticipation, "you will be serving me in a way that you've never done before." She smiled wickedly, her pointed teeth gleaming in the candlelight. "I'm going to make you my personal asshole slave."
Suck's heart raced as he tried to comprehend what his mistress was suggesting. His breath quickened in anticipation and fear of what might come next.
Alex stood up from her throne, revealing her naked body. Her ass cheeks were plump and smooth, glistening with anticipation. She turned around, presenting her perfect behind to Suck.
"Kiss it," she commanded. Obediently, Suck leaned forward and pressed his lips against her ass cheeks. He could feel the warmth of her body seeping into him, making his cock twitch with excitement.
"Now," Alex continued, her voice taking on a husky tone, "prove to me that you're worthy of being my asshole slave." She spread her legs wide, giving him full access to her most private parts.
With trembling hands, Suck reached behind him and began to explore Alex's tight, puckered asshole with his tongue. He licked at it gently at first, but soon found himself eagerly lapping up every drop of her pungent, shitty goodness.
Alex let out a moan of delight as she felt her slave's tongue probing deep into her anus. She reached down and gripped his hair, pulling him closer to her as she grunted and pushed her heavy shit load into his eagerly waiting mouth.
As Suck tasted the bitter mix of feminine fluids and feces, his cock stood at full attention. He knew that this was exactly what he had been trained for - to become a complete and utter shit slave to his beautiful mistress.
Hours passed as Alex relentlessly purged her bowels into her faithful slave's mouth. Each time she emptied her asshole, she would smile down at him, her face beaming with pride. And each time, Suck would obediently slurp up every last drop of her precious shit.
Finally, Alex pulled away, leaving Suck panting in exhaustion but filled with satisfaction. She turned around and lowered herself on his face, resting her asshole gently against his lips.
"Well done, my loyal servant," she murmured. "From now on, you will be known as Shitty Asshole Slave. Your only purpose in life is to worship and devour my excrement."
With that, she lifted her robe and revealed her shiny, glistening asshole once again. Shitty Asshole Slave closed his eyes, knowing that this was where he belonged - at his mistress's feet, ready to serve her in any manner she desired.
