Vanity

'I'm...' she was going to say sorry to her Mistress, but as Carly raised a hand to smack the other side of slave's face, she fell silent. Overpowered.

Carly lowered her hand and opened her bedside drawer again. Slave didn't quite see what she produced this time, but then again she didn't need to see it to know that it was a cattle prod. Or at least, something very much like one: something Carly had built herself, actually.

The curly-haired vixen climbed slowly atop her slave, facing away from her, allowing her a good look at her bum as she did so. Then even more slowly, she lowered herself. As Carly's pussy neared her slave's face, too close now to focus her eyes on, the restrained girl had only the view of her tormentor's silky smooth back to enjoy. Her graceful hips curved into her waist, and her perfect skin glistened in the low light as her golden blonde locks flowed over her shoulders. Slave couldn't help but want to feel those locks all around her own face, tangling her up, but there was no such luck tonight.

Then she was smothered. After so much practice, Carly had the positioning spot-on so that the crucial part of her reached slave's waiting mouth perfectly. Slave's whole face had been obscured now, and as Carly fixed herself onto her seat firmly, her tender skin moulding to the shape, breathing became impossible for her slave. The whole experience obscured not only her vision, but her capacity to think. It wouldn't be long before her need for oxygen took over, and she didn't have to be told what Carly wanted. No, she knew exactly what she was to do. So she did it.

Carly squirmed as slave's tongue lapped at her. Tingles roamed around her clitoris as the moistness grew and her slave's skilled, slow yet intense licking made her smile. She could feel that her slave was trying to breathe, so she pressed down harder. Desperation made her tongue work faster, but that only did the trick to a point – beyond that, it became more tickly than orgasmic.

'Slow it down,' said Carly.

But slave's tongue only managed to slow the pace for a few seconds. Her face buried, she was unable to take a gasp, her head was starting to swim and her lungs felt hot. She wriggled and tugged against the restraints, her licking becoming more and more frantic.

'I said,' Carly dealt a blow to slave's inner thigh with the electric prodder, 'slow it down.'

Of course there came a stifled yelp. And now so desperate for air, the sensations Carly had forced her slave to give her were becoming less and less sexual. She could even feel the suction between her slave's airways and her own skin as she tried desperately to breathe in. Stars formed in her slave's mind, and then without another word Carly hoisted herself up just a little.

An enormous gasp whirled around her pussy as her traumatised slave caught her breath. The cuffs chafed at her wrists and ankles as she tugged and writhed, her blurred vision returning to normal just in time for Carly to hit her again with a few volts of power and force another screech from her mouth.

'Stop moving around, you're annoying me,' said Carly.

'I'm...sorry...but–'

Prod.

'FUCKKK!'

Carly jabbed her again, and another gasp. It almost brought tears to slave's eyes.

'Please!!' slave begged.

Zap.

Another scream. This time though, slave realised her mistake. For every time she spoke, she got a nasty jolt to one or the other of her thighs. So this time she bit her lip hard and kept quiet.

Carly lowered herself back over her slave's face. It turned her on hearing slave's frantic heavy breathing stop instantly, so much so that she gave her another prod just for the hell of it. A stifled scream and then her tongue began to work again, deeper, more passionately this time. It was clear to Carly that her slave was beginning to need this ordeal to come to an end, and as such her tongue had gone into autopilot now. It lapped lusciously at Carly's clit. Slave's body began to writhe again.

'I'm not getting up bitch, not til I've cum,' Carly panted eagerly.

She zapped her slave right between the legs, enjoying the spasmodic deep thrust of her tongue that mirrored the way she tried to arch her back. Carly threw the prod aside and held her slave down by the hips, bowing her head in anticipation as her orgasm drew closer and closer. Her long hair made slave's skin tingle, and that made her give a final push with her tongue that sent Carly over the edge.

Oblivious to her smothered slave's predicament, she reached the point of no return. Her movements now were out of her own control – the onset of orgasm had taken her over, making both she and her slave helpless to what happened next. Carly rocked her hips, grinding harder onto slave's face and releasing her juices without mercy. Her body fell forward into an almost 69 position and her hands clamped around her slave's thighs like vices. Deep ecstasy pulsed through her body, and her screams must surely have been audible to her neighbours. Even though she lived in a detached house.

It blew her mind. There was nothing in the world right now but Carly and her poor, helpless slave. Carly's body was still awash with tingles and she convulsed blissfully as the climax reached its peak, then began to relax as it subsided. Her body was sweaty and her breath hot and irregular. And then she realised that her slave was totally without movement.

Carly slid forward, and at once both loved and hated the feeling of her pussy parting company with her slave's face. She turned around and straddled her slave's glistening, perfect body with her own and giggled. Carly had overdone it again; poor little slave girl had passed out through oxygen deprivation, and now there she lay, her face moistened by Carly's pleasure. Turning sticky.

Carly wasn't concerned. She simply took the opportunity to enjoy a taste of her slave's skin while she was out. She kissed her vulnerable bare chest several times, up and down, and let her tongue linger around slave's nipples. Then she kissed her lips, aroused not only by the taste of herself there, but also by the lack of any response. Finally as slave's eyes flickered, Carly slipped her body into cuddle position and let her arm sit comfortably across slave's chest.

Slave came to, breathing sharply for a few seconds. She blinked.

'Fuck,' she mumbled, everything still fuzzy. 'Thought I'd make it that time...'

Her weakened voice was music to Carly's ears. 'Mmmm, you wanted to be there to feel me orgasm, didn't you?'

'Yeah...knowing how amazing it was.'

'Too bad,' said Carly.

Slave realised that her lips were moist and licked them instinctively. She could taste Carly.

'I love it when you squirt,' said slave.

Smile. 'Only you can make me do that.'

Carly used her gentle tongue to remove the rest of her juices from her slave's face. Of course she drew out the process for as long as possible, exploring every inch of her face and yet carefully avoiding the lips. Just to frustrate her.

When she stopped, slave looked her in the eyes. 'Let me free so I can hold you.'

Carly giggled again.

'Let me free. I KNOW you want to.'

'Bitch,' Carly chastised, for her slave was right.

The dominant woman rolled over and plucked the handcuff keys out of her drawer, dangling them just above Carly's mouth.

'Or I could have you swallow these,' she tormented, 'and just leave you like this when I go back.'

Slave's eyes narrowed.

'Okay, okay,' Carly gave in.

She unfastened the ankle cuffs first of all, and slave drew her legs up in relief. Then she kissed slave's lips in passing as she made for the bedhead and released her wrists too. She flicked the keys back into the drawer and resumed her cuddle position.

Slave's arms slipped around Carly's body, their bare skin awash with goosebumps. Like a single entity, at once now they clamped arms around each other, legs too, entangled like wires behind the TV set – and held each other as tightly as humanly possible. There was no kissing now, no fondling, just two bodies locked in a hypnotic hug. They couldn't let go. With both of them satisfied, there was no feeling in the world like his, nor could there ever be.

'I'm really looking forward to this one,' Carly whispered.

'Go and do it,' said her slave, 'before we destroy the universe or something.'

They released their grip, knowing that if they didn't do it now they never would. Without another word, and without laying eyes on her irresistible slave again, Carly left the room completely naked and headed downstairs to her study. She unlocked the door eagerly and waves of excitement washed over her as she hurried in and powered up her amazing machine.

Carly was a genius of the first order. Her IQ had been measured on three separate occasions as 188, 204 and 196 respectively. She was in all likelihood the best scientific mind in the world, albeit somewhat undiscovered. And here in her study sat the thing that she had decided to devote all of her amazing intelligence to building – and build it she had, though it had taken two years and cost her her entire lottery jackpot to obtain the parts and components necessary.

There were so many potential uses for a time machine, but Carly had selected only one: satisfying her amorous lust for herself. That crazy sexy turned-on feeling she had whenever she looked in the mirror.

For three weeks now she had been using this piece of apparatus to quite literally have sex with herself, several times a week. She needed now, as always, to try to remember everything her slave had done tonight – for in a moment, she would BE that slave, and experience from the other side of the equals sign everything she had just done to her. So she had to replicate her slave's movements, because otherwise she would be changing the past. And as anyone who's seen Back to the Future must surely know, doing that is probably not a good idea.

She set the controls for 5:55pm. Then she pushed up the slider that activated the machine, and sat in a chair hooked up to it with electrodes and curly wires. She let her body relax.

BANG.

A little disorientation, and then everything calmed down. Don't be fooled by all those sci-fi films – time travel isn't all blinding light and tumbling through surreal wormholes. As Carly had realised, it was actually quite a simple process once you figured it out. And quick too, for here she was now, in the past. A glance at the clock over the fireplace told her that the machine had worked. She had just moved two hours back through time.

She crept out of the study and listened. She did it always, even though she knew full well that her earlier self wouldn't even be home yet for another ten minutes or so. She made her way up to the bedroom. It was all tidy, the bed was neat, just as it had been before she got in from work. The stage was set.

She grabbed her favourite perfume bottle and left the room. Spraying it into the air downstairs ready to entice her past self, she returned to the bedroom and finished with a couple of extra blasts to her neck. Then she fished the handcuff key out of her drawer and slipped it onto a neck chain that she always kept for this very occasion.

Time was of the essence. She heard her own car pull up outside, and her heart raced a little. She took up her signature provocative pose in the chair by the window, and waited for the sound of her past self's key in the lock downstairs. She couldn't help but touch herself a little as she heard her Mistress' playful giggle downstairs. She wanted to ambush her two-hour younger self the minute she walked through the door, but she daren't; that would be changing the past.

And that realisation was enough to force her into 'good little slavegirl' mode. She had to do exactly what younger Mistress Carly told her to now, not only because she wanted to, but because the safety of the space-time continuum depended on it.

After what seemed an age, Mistress walked into the room, wine glass in hand. God, she looked sexy in her expensive clothes. There was no wonder she fancied herself so.

Carly smiled, eager for Mistress to use and abuse her naked body. As she watched her past self put her wine glass down and begin to undress, she knew she was in for one hell of an experience. Again.
