Dropping down to his knees, he gathered up the two-part attachment arm that fits into the spreader bar holding her legs apart. He slid it into the center position and locked it with a screw. Loosening the middle hinge, he angled the top part of the arm to about three inches from her clit. When he was satisfied it was properly placed, he got up and went back to the toy area, returning with the Magic Wand, already plugged into a heavy-duty extension cord, trailing it behind him. He cycled between Off, Low and High as he walked. He stood before her for a moment, letting her study her new tormenter. The mask was slowly started to slip away, as both fear and hate played across her face. Turning it off, he secured it in the clip, so that the head was resting on her pussy, with no way for her to escape it.
That's when the begging started.
Muffled screams, pleading for him to just beat her, to not turn on that damn thing, to untie her came flowing from behind the gag. Though he appeared unmoved, he listened intently, as well as watched her hands for the pre-arranged safe word or signal. It never came. Then, as quickly as it started, her outburst ended, and silence once again filled the room. He gave her a questioning look, asking if she wished to continue, and she nodded in the affirmative.
Still looking into her eyes, he reached down and activated the wand on low speed. Closing her eyes, she dipped her head, with the only outward sign of her struggle being a pair of clinched fists. Walking around her, he watched as she began to tremble, and fluids started to run down her legs. It took about five minutes before the first orgasm hit. Her knees buckled and a low moan came from her throat. Using two of his fingers, he found her cunt a soupy, dripping mess. Now she was ready.
Stepping back in front of her, he reached down and turned the device to high. Her eyes snapped open, and the wail of a demon twice her size exploded forth. A puddle gathered at her feet, as orgasms separated by only a minute ravaged her body. A film of sweat gathered on her skin, as her body gyrated through the assault. Thanks to his perfect placement of the wand, no matter how she moved her hips, she couldn't get away from the powerful vibrations.
Moving around to her backside, he gave her two solid strikes with the tail, across her ample ass. This, of course, drove her pussy back onto the deadly head. Back and forth they went, with the strikes getting successively harder, till her behind was beet red, with some areas beginning to bleed.
Studying her, he noticed that the screaming had stopped and that her movements had slowed. Concerned, he went around to the front of her and saw that she'd slipped off to sub-space, barely cognizant of what was going on around her. Turning off the wand, he unbuckled and removed the gag. Then he removed the clamps from her nipples and tossed them aside. After releasing her legs from the spreader cuffs, he detached her wrists from the hook above her head, catching her in his arms as she collapsed.
Walking her slowly over to the bed, he helped her lay on her stomach. He opened the drawer on the nightside stand and pulled out the first aid kit. Gently, he began to treat and cover the open areas on her back and butt, while softly telling her how proud she'd made him and how well she'd done. Once he'd finished, he laid beside her and wrapped them both in her favorite blanket. He let her find a comfortable place in his arms and, before laying her head on his chest to go to sleep, she whispered in his ear "Thank you, Sir."
