Riding

Her brother was a sex beast who fucked her like nothing Emma had ever experienced. How could Mistress have lured him here to make him a sex slave, making him do this horrible thing? She was broken; nothing worse could happen to her, especially since she felt her pleasure rising. Her brother was a stallion but also a fabulous lover.

For long minutes, he didn't weaken; on the contrary, encouraged by strokes of Mistress's riding crop, he increased the speed and brutality of the penetrations, keeping her in a state of stupor. Despite all her attempts to resist, she felt her pleasure rise, amplified by her shame.

• Mistress, can I come? asked her brother.
• Yes, go ahead.

She came wildly at his words as he came inside her in long thrusts that were only interrupted when Mistress pulled him out of her vagina and guided him towards her anus.

• No mercy, Mistress, no, begged Emma.
• Shh, shut up, he can't hear you, he only hears my orders. You fuck this female dog ! she said to her brother, who continued to be hard as a bull in heat.

Just as savagely, he thrust into her, dilating her rectum. She screamed in despair, but also because she felt like the worst human wreck; she had wanted the worst, and she had gotten it.

Emma's cry turned into a moan as her brother's thick rod pushed deeper into her rectum, stretching her mercilessly. The pain was blinding, but shamefully mixed with perverse pleasure—her body betrayed her as she pressed against him. Mistress's laughter escaped as if drunk on its power, her riding crop streaking Emma's trembling flanks as if she were at a horse race.

"Harder," Mistress purred, her fingers tightening the leash around her submissive's neck, forcing her rhythm to accelerate. Emma's vision blurred as her hips were pulled back with each brutal thrust, the wet slapping of her skin drowning out her gasps.

Emma's breaths were in gasps as her brother's hips penetrated her with relentless force, each thrust sending waves of shame and pleasure through her trembling body. The pain in her rectum was raw, unbearable, yet her treacherous flesh clenched around him, squeezing him as if begging for more.

Mistress landed a sharp slap on Emma's rump, forcing her back to arch further, offering her body to her brother's brutality. The muscles in her stomach clenched violently as he pinned her in place, his member pulsing inside her like a hot piston.

Emma's scream turned into a muffled moan as her brother's hips penetrated her with animal force, his cock stretching her to orgasm. The pain Mistress inflicted as she slapped her buttocks intensified, burning and intense, merging with the inexorable fullness within her. Her body convulsed, betrayed by the nauseating pulse of pleasure that tightened with each brutal blow.

"Slower, please," she sobbed, but her brother only grunted; he couldn't hear his sister, his fingers digging into her hips with force.

• Mistress, I can't take it anymore, I'm going to...
• Go on, my darling.

Emma felt the cum flow hot and sweet into her rectum.
