Uncompromising

Her brother roughly removed his soiled sex from her, remaining at attention, awaiting Mistress's orders.

• Cleans his sex by licking it.

Emma sighed at the sight of his sex covered in a nauseating mixture, sending back to her an image of what she felt about herself.

A swipe of the riding crop brought her back to reality; she got down on her knees and began this humiliating task.

Mistress cracked her riding crop against her thigh, the sharp sound resonating like a challenge as Emma licked her brother's glistening sex with humiliated slowness.

Each stroke of her tongue over the taut skin brought a shudder of disgust from her, saliva mingling with the remnants of their forced union. The acrid taste filled her mouth, metallic and musky, and she felt her stomach tighten, but the silent threat of the whip held her in place.

When she finished, Mistress ordered her brother.

• Fuck her mouth.

He felt for her head, tilted it, and without hesitation pushed his cock, still flexing, all the way down to her throat. She nearly vomited, as he treated her like a present to make him obey Mistress.

Emma's throat contracted violently around him, her gag reflex fighting the brutal intrusion, but her brother pushed deeper, crushing her uvula beneath his swollen head.

It was like a snake about to spit out its condemnation, pressing forcefully against the back of her neck, pushing ever deeper.

Emma gasped, her nails digging into her brother's thighs as he pounded her throat with mechanical indifference. Thick drool flowed from her stretched lips, mingled with silent tears.

He acted as if he wanted to pull out.

• Mistress, I have to go to the bathroom, he said urgently.

She laughed.

• That's what she's here for too, empty yourself inside her.

Emma wanted to pull out, but Mistress pressed her head against her brother's pubic bone, his penis buried deep in her throat, when with a moan, her brother emptied his bladder into her throat.

Tears blurred Emma's vision as her brother held her head in place, his fingers clenched in her hair like claws. Each movement of his hips pushed his cock deeper into her throat, and she felt her own saliva quickly mix with the overflowing urine, running down her chin.

Her nose pressed against her sweaty stomach also released the excess. She was choking, her throat muscles contracting involuntarily around him, trying in vain to control the flow.

She pounded at him to make him let go, but to no avail; he waited until he had emptied his bladder to release her.

Emma was still choking, her throat burning and her face streaming with a mixture of tears and urine, when the mistress's riding crop came down on her back with a sharp crack. "Don't stop, bitch," the voice above her growled as her brother, his hands still gripping her hair, began to move again. She felt his penis harden against her tongue, the acrid taste of urine making her gag.

Finally, after endless minutes, he finally spat out the last drops of semen.

• So satisfied?

Emma was crying.

• I think I've found your limits. I might deliver you to him again. Do you want me to show him who his partner was?

Emma threw herself at her feet, begging her. She could bear what she had done, but she would never be able to bear the look on her brother's face, so defiled.
