Show her how to REALLY cum...

'Okay then,' shrugging, you wander away from the rack, forcing Karen to crane her neck to keep you in sight. The chair you were waiting in before she got here remains reclined in front of the device, and you sit down, make yourself comfortable, and fold your hands in your lap before you continue: 'Cum, Karen.'

She whimpers this time, a pitiful and fetching sound, before her second orgasm hits. It shivers up from her hips this time, her ass clenching and rising up from the table before the sensation spreads and grips the entirety of her form. Karen's green eyes close as she writhes with the feeling, far calmer this time than the first, and you realize that you've left out a word this time; you didn't tell her to "cum hard," this time, and it's a visibly different show this time around because of it.

So, choosing your words carefully matters, here...

Karen finishes her climax faster this time, another result of your careless wording, but it hardly matters. Smiling gently, you repeat the order, sending another orgasm pulsing through the Scottish woman's pussy with only the power of your voice. There is, in the end, barely a moment of reprieve from the second climax to the third, and you sit back to watch Karen cum again for your amusement.

And again. And again. And again.

From your comfy, reclining seat, you pull the orgasms from the lovely lady Gillan's body, the effort you invest to cause them far outmatched by her own effort in receiving them. That sweet, pale face burns crimson with shame as your orders dance across the surface of her mind, bending the whole of her being to your desires, and her body betrays her, over and over. That treacherous cunt clenches on nothing more times than she can count, wetness dripping freely, soaking her panties. Her clit, throbbing and raw, rubs against that sticky mess as each climax forces her to move and squirm. Until, finally...

'Cum, and don't stop until I say so.'

This is the one, the true test of the hypnotic controls embedded in Karen's mind. No human body would do this on its own, after all; Karen groaned and trembled through yet another orgasm, while you check your watch, only partly to time how long you can make this one last. Five minutes pass, to a soundtrack of sexual Scottish screaming, and you look up at Karen with an expression of mock surprise and very real amusement. She looks back at you, her eyes wide and pleading, a body already oversensitive and now in overdrive, filled from head to toe with agonizing ecstasy.

You go to ten minutes, watching the girl's nipples tighten to impossibly hard nubs beneath her dress, and then you go to fifteen just out of curiosity.

For a moment you consider going to twenty, but Karen had been reduced to simply trembling in her bondage, her breath coming in rough, uneven gasps. The helplessness of her situation seems to have gotten to her, and she's no longer putting on a good show for you.

'You may stop,' you sigh, and almost immediately she slumps, exhausted, down onto the rack. 'That was fifteen minutes, Miss Gillan. What do you think?'

'Please...' Karen whimpers, a tear rolling down one perfect cheek. 'Please don't make me... I can't...'

'If you don't play along with me, I'll leave you like that all day, you shameful little whore. Do you understand your situation now, Miss Gillan?'
