Electro stimulation.

I decided to use one of my favourite devices and opened the black attache case it was kept in. My pussy spasmed in anticipation as I gazed lovingly at my toy. Nestling in compartments in the case were the various components of the samurai, an electro stimulation dildo. The dildo itself was a modest seven inches in length with two sides of polished steel separated by a black strip down the middle. The design was beautiful, the sleek curved dildos were each hand tooled by craftsmen and the hefty price tag showed in the quality. The samurai was a double pole electrode and behind the curved phallus of the dildo was a chunky rubber handgrip. I plugged two leads into the base of the handgrip and the other end of the leads into the control box.

Taking a tube of lubricant specially formulated to be used in conjunction with the samurai I coated the dildo liberally and approached Cassie. Her shaven pussy looked delightfully inviting and I set the dildo down for a moment whilst I prepared Cassie. Parting her dark lips I squirted a generous amount of lube into her and used my fingers to coat the inner walls of her glistening quim. She moaned and wriggled as I worked, her pussy clenching in a vain attempt to prevent my fingers from intruding. Satisfied that she was sufficiently oiled I inserted the samurai slowly, twisting the the dildo to ease its passage into her tight cunt. I secured it in place with leather straps and watched for a moment as Cassie worked her vaginal muscles, attempting to push the dildo out of her. The effect was delightful as the protuding handle of the samurai bobbed up and down as Cassie vainly tried to expel the invasive dildo.

I left Cassie to squirm and continued my preperations. I dragged a bondage chair over to my pet so I could sit just in front of her and watch the fun in comfort. The control box I fitted to a holder on the arm of the chair and plugged it into a wall socket. On my table was a second case containing another samurai, which I prepared identically to the first. Making myself comfortable in the chair facing Cassie I parted my legs and worked more lubricant into my pussy. I slid the second samurai into my eager quim, feeling the sleek cold shaft filling me. I connected my own dildo to its control box. I turned on the control boxes and felt my cunt spasm as the first tingle of electricity was delivered to the moist depths of my sex.

"MMMMPPPHHH." Cassie protested in high pitched outrage as the samurai inside her delivered it's charge.

I sighed in satisfaction at the noise she made and adjusted the controls to increase the frequency and pulse of the dildos.

"MMMHH NNNGG GGGAARRHHH." Cassie was struggling again, her suspended body twisting and swinging as she wriggled and shook. "Grrr nnnhh ooofffggg."

I giggled as I watched her, thrusting the samurai hard up my tingling pussy and feeling my muscles spasm with each pulse of electricity. I could see the handle of Cassie's dildo jerking as her pussy convulsed with each jolt of electricity. I kept up this torment for a long time, feeling through my own dildo exactly what Cassie was experiancing. Both of us were panting hard and making incorent moans and I found the intimacy of our shared stimulation to be intensely erotic. I came hard, one hand gripping the chair arm and the other thrusting the dildo savagely up my cunt. As my breathing slowed and I drifted down from the plateau of my orgasm I watched Cassie tremble and jerk as her will to deny the intense stimulation of the samurai crumbled.

"MMWARRR." She screamed into her gag, surrendering to the shame of being **** to orgasm against her will for my amusement. Her body heaved as the tremors of climax shook her slender bondaged frame. "Nnnn nnnngg."

I switched off the dildos as her tremors subsided, satisfied that the lesson would be clear to Cassie. Despite her will to resist I could **** her to cum. She would be cursing her body's weakness now and the seed of doubt in her own nature had been planted. I would let her down now and leave her alone to think about what had just occurred.
