Long rubber whip.

Ah, yes. The fast road to submission. You slide the long black monster out of the case, crack it left and right on the ground with quick, professional movements.

Without even stepping closer you snap it at the sawhorse Natalie is bound to, she jumps in terror and retreats as much as she is able, her breasts jiggling even in their bondage.

You flick the long strip of rubber slowly over her thigh and just let it lay there like a black snake, before whipping it back, stinging her hard on the hip.

You step alongside her and slap the whip thick against her back, the long length of rubber snaking around her like a living thing, wrapping up her breasts. You pull it and it pulls tight. She shrieks in surprise, no hint of her defiance, already whipped away. Now we have fear, and blunt animal respect.

You rub the rubber up and down over her skin before shaking the whip loose and taking a distance behind her.

You crack her softly, but sincerely, finding the skin of her shoulder blades, her lower back, the top of her butt, the whip whistling through the air and snapping into her skin with a yelp of pain through the ball gag.

You walk around to the front and flick the rubber out so it drops meekly against her exposed, shaved pussy - the terror in her eyes does all of the work, you don't even need to sting her again.

You walk up to her shivering body, and softly rub her pussy lips, your other hand taking up her collar. "There, there Natalie. I'm here. You took a good beating. Feeling better now? Can you be good for five minutes?" Her red, wet eyes nod at you, her body curling in response to your soft touch.
