As Chrystal finished her business on the bound slave's face, she let out a satisfied moan and looked over at Nataly. The brunette beauty was eagerly waiting for her turn, her heart racing with anticipation. Chrystal smiled and nodded, signaling for Nataly to proceed.
Nataly approached the slave with determination in her eyes. She had always been curious about coprophilia, but never had the courage to act on it until now. Gripping the slave's hair in her hand, she pulled his head up towards her, exposing his openmouthed expression filled with fear and submission.
Without further ado, she released a loud fart onto the slave's face, her pungent ass gas filling his nostrils and making him cough reflexively. Nataly laughed, delighted by the reaction she was getting from her first victim. She took a step back, allowing the scent to envelope him before moving forward again.
This time, she lowered her perfect round ass onto the slave's face, feeling the warmth of her fresh shit seep into his mouth as he tried desperately to breathe through the disgusting odor. Her body shook with pleasure as she grinded against his face, moaning softly at the immense pleasure she was experiencing.
As she reached her climax, Nataly let out one last powerful shit, filling the slave's mouth and nose completely. Satisfied with her work, she pulled her sweaty body off the slave and stood back, admiring her handiwork.
The slave, gagging and sputtering, couldn't believe what had just happened to him. His eyes were watering, his nose was filled with the repulsive smell of shit, and there was a sticky, warm feeling coating his face. He tried to speak but could only manage a garbled noise as he struggled to breathe through the overbearing stench.
Chrystal approached him, a mischievous glint in her eye. She bent down close to his ear and whispered, "You know, slave, we can do this all night if you'd like. But since you're such a good boy, we might give you a break... for now." She stood up, smirking as she glanced at Nataly, who was still catching her breath from the intense orgasm she had just experienced.
The girls helped each other clean up, giggling awkwardly as they scrubbed the shit from their bodies and the slave's. Finally, they untied him, leaving him lying on the ground, exhausted and traumatized. As they walked away, Chrystal turned back to look at him one last time, her expression a mixture of amusement and power. The slave shuddered, knowing that he was at their mercy and they could do this to him again anytime they wanted.
