"No!"
He slapped her ass, watching with a grin as her asscheeks jiggled, then reddened under the light blows. Against her will, Cindy let out a fart, her cuntal muscles tensing up while a trickle of juice oozed from her fuck slot.
Jack grabbed a wrench from the top of the workbench. He teased her, pressing the tool against the side of her face for a moment.
Cindy gasped.
Jack inspected the tool for a moment, then he turned the small screw near the top until the jaws were about a quarter-inch apart. Bending over, he rubbed her tits with both hands, bringing the wrench around until the head was touching her long, pink nipples.
Cindy flinched, shivering at the cold metallic touch. She felt him twisting the wrench around, bringing it up so her left nipple tit between the jaws. He began twisting the tiny screw, until the cold ribbed steel was pressing against her tit-tip.
Cindy panicked, rolling her ass around while her eyelids flickered with fear and pain. The tool was cinching down on her nipple, crushing the tiny nub and sending streamers of hot pain rushing up and down her spine. She tried yanking back, feeling the ropes cutting even harder into her flesh.
He turned the tiny screw three more times. Cindy jerked her head up, shaking the loose hair from her eyes and letting out a scream. He was crushing her nipple, smashing the long pink nub between the jaws of that awful instrument.
Cindy bobbed her ass up and down, feeling the rough wood cutting into her belly. Her knees banged against the legs of the sawhorse. He was really hurting her now with that awful wrench, the jaws squashing her pink nipple flat.
Then Jack let go of the tool, letting it swing down and tug her tit hard with its weight.
Cindy screamed, fearing the wrench would rip her nipple off.
"Now, for the other one."
Cindy managed to control her sobbing, shaking the hot tears from her eyes as she felt the painful, puffing weight on her right tit. The wrench pulled her tit down, stretching it, while the jaws still bit agonizingly into her nipple.
