Princess Donna World famous Mistress, helpless on the sybian made to cum like a common whore

Princess Donna spent years grinding girls raw on the sybian. The loudest, meanest vibrator alive. Strap a woman down, impale her on that saddle, and her cunt will spit out climax after climax whether she wants them or not. Now the cuffs bite into her wrists. Her own thighs are locked open. Donna is stuck, helpless on the machine she once mastered. The first jolt hits her clit like a live wire. She jerks, swears, then screams—part pain, part pleasure—as the motor drags the first orgasm straight out of her. Within minutes the tough Mistress is shaking like any common whore. Sweat streaks her face. Her hips grind on reflex. Every new pulse cracks her open again, forces another shuddering come from her bound, aching body. She can’t slow it down. She can’t switch it off. Nothing will stop the next brutal wave, or the one after that, or the one that follows.
