As Chrystal stepped into the living room, she noticed the tangy smell lingering in the air. Her heart raced with anticipation as she remembered what was waiting for her. She approached the stairs where her friends had tied up the naked slave, their test subject for today's scatological activities. The man's body twitched slightly as he sensed her presence. His eyes, full of fear and pleading, begged for mercy.
Chrystal ignored him and walked up to the group of giggling girls standing over him. "Alright, girls, let's get started," she said, her voice calm but commanding. They parted reluctantly to give her space as she mounted the step beneath him.
With deliberate slowness, Chrystal lowered herself onto the man's face, feeling his warm breath on her skin. She closed her eyes and took a deep breath, trying to control the excitement coursing through her. She pushed down her panties and positioned her slightly soiled pussy above the slave's mouth. With a hesitant look, she sank into his mouth, feeling his tongue against her folds. She moaned softly, the taste of her arousal filling her senses.
Under the mask of pleasure, Chrystal could sense the panic brewing in the slave. She could feel him trying to push her away, his neck muscles straining against the ropes restricting him. But she kept his mouth open with one hand, determined to take as much as she could. She rocked her hips back and forth, grinding her soaked pussy against his face as she felt herself getting closer to climax.
Finally, Chrystal reached her peak and cried out, her body shaking with the intensity of her orgasm. She pulled away from the slave's mouth and sat back, catching her breath. She watched as the other girls gathered around him, their eyes gleaming with an unholy mix of lust and triumph.
One after another, the girls mounted the steps and took their turns riding the slave's face. Some smeared his face with their shit, while others took pleasure in seeing their friends work him over. The man's cries and moans filled the room, but no one paid him any mind.
When they had all had their fill, the girls took turns cleaning the slave's face with their bare hands. They rubbed their wet fingers into his skin, smearing his tears and sweat along with the remnants of their excrement. They giggled and joked about how the poor man wouldn't be able to wash off all the scent for days.
As the last girl finished cleaning him up, Chrystal smiled warmly. "Well done, girls," she said, her voice filled with pride and desire. "That was quite the show. Now let's go find something else for him to enjoy." She stood up, feeling the weight of the day's activities pressing down on her body. But she was already looking forward to the next time she could indulge in her secret vice.
