For quite some time.

I watched Cassie for a minute or two. Each time the samurai inserted into her ass delivered a shock her whole body twitched in response. Though I'd shared her experiance with a similar electro stimulator in my own pussy earlier, I had no desire to repeat that now. When I first began to experiment with the bondage and domination scene I did swich roles, curious to learn the thoughts and emotions that would go through a slavegirl's mind. Physically the role was arousing, I do after all have an intensely sexual nature and acheiving orgasm was relatively easy. Mentally though, the submissive role left me cold. The feeling of control was intensely satisfying.

"Not so rebellious now are you?" I said to the girl. "Anal a new experiance for you is it?"

I heard a soft whimper from behind the gag in response. I smiled, her discomfort at having her tight asshole invaded was clear. With her legs bound up, Cassie was unable to close her legs and her shaven pussy spasmed with each jolt of electricity delivered up her ass. Now was the time to sow self doubt and confusion. I got a small vibrating pad that fitted over two fingers and began to massage her shaven slit. Her knees jerked in a futile attempt at closing her legs when the buzzing toy touched her sex.

"There, you like that better don't you?" I cooed to the girl, pressing the vibrating pad hard against her fleshy clitoral hood. "I don't think you'll be able to block this out."

She did try, screwing her eyes tight in concentration and making her body go rigid with the effort. I persevered, knowing that whatever distress she might be feeling inside there was no way she could ignore the clitoral stimulation for long. Sure enough after a minute or two of the madly buzzing pad pressing against her clit her pussylips took on a slick look as juice began to leak from her aroused quim. I could see drool running down her chin as she bit at her gag in frustration at her enforced arousal. The hotter I made her the vocal she became, moans punctuated by stifled yelps.

"Oh my word, you are getting wet down there." I teased her, as if she wasn't well aware of the fact. "I guess deep down you find getting tied and sodomised a turn on."

This elicited a louder moan and her eyes opened and flashed angrily. But behind her denial I detected a hint of doubt. Just a seed as yet and doubtless she was rationalising and suppressing the suggestion, but there nevertheless. I kept up the pressure, stimulating her clit until her breaths rasped past the gag and her bald pussy was dripping wet. Her eyes screwed up once more as her thighs twitched and trembled as I **** her to orgasm while the electric shocks continued to sting her anus. Where pain alone had failed the confusion of orgasming whilst being anally violated worked. Her eyes welled up and tears ran down her cheeks.
