Miss Yara walked over to her slave from behind. Her perfect round ass wiggled enticingly with every step, leaving a trail of anticipation in the air. She reached down and grabbed his cock, still covered in her warm, sticky shit, and began stroking it.
"You did well swallowing all that scat, Cosmo," she purred, running her thumb over his sensitive pee hole. "But there's more work to be done."
Cosmo moaned loudly, his eyes rolling back in his head. The mistress was a perverse temptress who only ever pushed him to his limits, but he couldn't deny how much it turned him on.
"I want you to taste yourself on my asshole," she commanded, turning around to reveal her divine rosette. "Get on your knees and lick me clean before you get your reward."
With shaky hands, Cosmo complied. He leaned in between Miss Yara's legs and took a deep breath of her musky scent. He could feel his heart pounding as he pressed his tongue against her asshole, lapping away at her sticky juices and traces of his own semen.
"That's it," she moaned, leaning back against the wall. "Now spread your cheeks for me. I want to see that cock of yours."
Reluctantly, Cosmo obeyed, spreading his ass cheeks apart to reveal his throbbing cock. It was still covered in his own saliva and shit, making it slick against his skin. Seeing him like this, exposed and vulnerable, only turned Miss Yara on more.
"You're such a dirty boy," she said, licking her lips. "I can't wait to fuck that filthy mouth of yours."
And with that, she pushed Cosmo to his knees. With a playful grin, she teased him further by rubbing his cock against her pussy, soaking it in her own juices before finally lowering herself onto his face.
Cosmo sucked hard on her clit, feeling her juices flow down his throat as she grinded against him. It was like nothing he'd ever felt before. She was the only mistress who could push him this far and he knew he would follow her to hell and back for another taste of her perversion.
As he felt her shuddering orgasm hit him, Miss Yara began to thrust backwards onto his face harder. He could feel her pussy walls squeezing his cock, milking him for every drop of cum he had left. But before he knew it, she was already pulling back, teasing him with a knowing smirk.
"You're going to learn some self-control," she said, grabbing his chin and meeting his gaze in the mirror. "If you want me to let you cum inside me, you're going to have to promise me you'll swallow every drop of cum that comes out of you."
Cosmo's heart hammered in his chest as he looked at her. Never had he been more determined to please her than in that moment. He nodded rapidly, eager to feel her pussy wrapping around his throbbing cock once more.
"Good boy," she purred, nodding slowly. "Now get ready, because when I tell you to cum, you're going to cum so hard it'll feel like your whole body is exploding."
And with that final tease, she plunged back down onto his cock, taking him deep inside her. He groaned loudly as she began grinding against him, setting a brutal pace that left no room for anything but pure pleasure.
"Cum for me, Cosmo," she growled, her fingernails digging into his shoulders. "I want to feel every drop inside me."
With a final thrust, Cosmo lost control. Wave after wave of pleasure crashed over him, each more intense than the last. He felt his cum splashing against her cervix, felt her walls pulse around his cock as he emptied himself inside her.
And then it was over. She pulled away slowly, her eyes lingering on his face in the mirror before she reached down and helped him to his feet.
"I'm proud of you, Cosmo," she said, wrapping her arms around him and pulling him close. "You're the perfect pet for me."
As he leaned against her, still catching his breath from the intense orgasm, Cosmo knew that he would do anything for this perverse mistress who had claimed his heart and his body. She was the one who understood him, who pushed him to be the best version of himself he could be. And as he felt her warmth and her love surrounding him, he knew that no matter what she asked of him, he would always be there.
