Diane squealed again, the hot, biting pain stinging its way from her nipples to her cunt and shitter. Billy had brought the leather thongs clown hard across her tit tips, the whip crushing the sensitive nubs and sending more pain and heat crushing into her brain. Her feet jerked back, tugging at the rope running down her spine and pulling the dog collar against her throat.

Diane screamed, feeling her lungs burst for lack of air. No. No. She had to be careful. She had to control herself, her movements or she would strangle herself! Looking down, she saw silly smiling grimly at her. He seemed about to say something, then stopped, setting his jaws firmly together. He looked as if he were readying himself for work, getting ready for the big attack.

Diane felt her muscles tensing, bulging against her sweaty flesh. Her right nipple felt as if it were half-torn from her tit while the muscles of her belly quivered. Billy stepped back, lightly tapping the crop against his leg again. Then he sprang into action, snapping the thongs back, then slashing across her lower belly.

Diane's face grew red and pinched as she trembled under the cutting blow. She looked down, half-expecting to see blood oozing from the wound. Another blow, this time across her face, brought the teen back to reality. She screamed through the gag. Another blow aimed at her belly once more made her snap back in the harness.

Moving around quickly, Billy jerked his arm back, then struck the leather just under her left kneecap with the middle of the crop. The shattering pain made her scream. Diane tried drawing her legs back a little farther and felt that move increase the smooth, warm pressure of the leather straps against her cunt. She shuddered, wobbling back and forth in the harness, feeling the leather now worming its way into her asshole.
