As Kyra continued to sit heavily on her stepfather's face, she felt an uncontrollable urge to defecate. With a smirk, she leaned forward slightly, allowing him to catch a glimpse of her engorged anus. It gave her perverse pleasure to watch the fear and desperation wash over his face as he realized what was about to happen.
Kyra gripped the edges of the toilet seat and pushed hard, grunting with effort as she emptied her bowels into her father's waiting mouth. He struggled feebly against the onslaught of hot, putrid feces, gagging and choking as he tried in vain to keep up with the flow. When she was finally finished, Kyra released him, leaving him gasping for air on the floor of the bathroom.
But she wasn't finished yet. With a sinister smile, Kyra positioned herself back on the toilet seat, spreading her legs wide and arching her back to invite him closer. As he slowly crawled towards her, she reached back with one hand, grabbing a fresh handful of his hair and pulling him roughly towards her.
With her other hand, Kyra positioned his face right between her spread legs, over the warm, wet mess that remained of her previous actions. He whimpered in distress as he felt his filthy job from moments ago about to become his new torment. She let go of his hair, and once again, he found himself unable to move as he waited for his cruel stepsister's next action.
Kyra leaned forward again, allowing herself to sink into the stench and warmth of her own fecal matter. She let out a laugh that was both evil and exhilarated as she began to move her hips rhythmically, grinding herself against her father's face. Her body weight and the motion of her hips served to smear the feces over his face, into his hair, and down his chest.
It felt incredible to have such control over someone she had once looked up to. As she continued to humiliate him in the most degrading way possible, she couldn't help but feel an odd sense of satisfaction welling up inside her. It was as if she was addicted to the power she felt, the knowledge that she could reduce her own father to nothing more than a helpless toilet slave.
Finally, spent and content, Kyra sat back, allowing gravity to pull her father's head out from between her legs. She watched with twisted amusement as he retched and gagged, desperately trying to expel the foul taste from his mouth. With a flick of her wrist, she sent a stream of urine arcing through the air, landing squarely on his face.
"Clean yourself up," she said with a dismissive wave of her hand, "And make sure you don't forget your place." She glided out of the bathroom, leaving her father crumpled on the floor in a filthy, sobbing heap.
