**"Don't move. This will hurt less."**

Emily raised her hand, studying the taut curve of Ai's buttocks. The skin was slightly flushed from previous sessions, marked by subtle lines where the ropes had pressed harder. Perfect. She breathed deeply, feeling her pulse quicken as she calculated the angle.

*Tchack.*

The first slap echoed in the studio. Ai arched her back with a hoarse groan, but didn't move—only buried her fingers deeper into the carpet, her knuckles whitening.

"Count," Emily ordered, running her fingertips over the warm skin.

"U-one," Ai stammered, her hips trembling.

The second slap came harder, overlapping the first pink mark. This time, Ai screamed, pushing her breasts against the floor as her legs involuntarily spread.

"Two," she sobbed, feeling the heat spread.

Emily watched the wet reflection between her thighs before raising her hand again. The third slap was delivered with an open palm, covering almost her entire right buttock. The flesh trembled under the impact, rippling in slow motion.

"Three—ah! Four! Five!" Ai gasped as Emily quickened her pace, the slaps merging into a cruel cadence. Her voice broke on the sixth, turning into a continuous whimper.

On the tenth, she was truly crying, her face pressed to the floor as her body writhed. Emily stopped abruptly, squeezing the throbbing buttock hard enough to make Ai scream again.

"Good girl," she whispered, caressing the overheated skin. "Now turn around. I want to see your face."

Ai rolled over with difficulty, revealing her swollen breasts and throbbing clitoris. Her thighs were soaked, her muscles trembling with each gasping breath.

Emily smiled, wiping the tears from the girl's face with her thumb.

"Ready for the next round?"

The moan she received in response was worth more than a thousand words. Ai's breath hitched as Emily's fingers slid down her sternum, stopping just above her damp, curly hair. The studio lights cast sharp shadows between their bodies—one in a clinically controlled posture, the other broken and malleable.

"You're dripping on my floor," Emily observed, slipping two fingers between Ai's swollen lips without warning. The young woman shuddered, a broken sound escaping as Emily slowly parted them. "Is this what you wanted? To be used like a cockroach—"

"No!" Ai arched her back, her thighs tightening around Emily's wrist. "I—*nngh*—wanted you—*ah!*—to really destroy me."

Emily's laugh was grim as she withdrew her glistening fingers. "Then kneel." The transition from pain to **** anticipation made Ai's movements clumsy. She barely felt the cold metal of the restraint bar fastening around her ankles before Emily **** her to put similar handcuffs behind her back.

"Tell me again," Emily purred, pulling the violet wand from its case. The crackle of electricity made Ai groan. "And this time..." She pressed the vibrating tip against the inside of Ai's thigh. "*Scream* for me."

The first shock coursed through muscles and nerves like lightning. Ai's back arched violently, her scream dissolving into guttural sobs as her body writhed against the restraints.

Emily watched, fascinated, as the scent of burnt skin and excitement filled the air. She slid the wand upward in a slow arc, pausing to circle Ai's clitoris until the young woman's cries became inarticulate, her hips moving against the empty air.

"Please," Ai pleaded as Emily finally withdrew the wand, her voice hoarse. "More. *More.*"

Emily wiped the sweat-dampened hair from Ai's forehead, her smile revealing all her teeth.

"Oh, darling... I'm just getting started."
