'Relax, you'll find this a stimulating experience, believe me,' Vanessa taunted as Zoe felt the rope around her wrists being loosened. One of her arms was then pulled towards the top corner of the bed. Zoe couldn't see anything but she guessed that Auda was holding her arm while Basil fastened a wristcuff upon her and Vanessa sat astride her to keep her immobilised.

In no time at all both Zoe's arms were tied outstretched and she was groaning fearfully.

'Hush now darling,' Vanessa soothed, 'I promise you, the pain will be more than matched by the exquisite pleasure.'

As she spoke Zoe felt the girl stroking her sex, her fingertips brushing tantalisingly lightly against her vulva, until her sex juices started to flow and she squirmed and sighed through the gag as she was made more and more aroused.

'Clamp the wires to her labia. Her juices will keep her nice and wet there and the current will flow easily,' Auda said.

Zoe writhed desperately as two small bulldog clamps were fastened to the soft outer folds of her vulva. She could feel the delicate wires trailing over her legs and she was panting hard in nervous expectation.

'Okay, give her a first taste,' Auda ordered.

Zoe tensed her body expecting an unbearable pain to flash through her body. When the first shock came though it was no more than a hot, sharp stinging that quickly spread from her sex through her tethered body like a wave. She groaned through the gag, tossing her head and struggling against the straps that held her down. The ache that the shock created in her sex was agonising and her clitoris especially seemed to suddenly be throbbing madly.

'More.'

At Auda's order, Zoe heard a faint click and the electricity that was rippling through her helpless body doubled in its intensity and force. Zoe jerked her arms and legs frantically against the leather restraints and shook her head feverishly from side to side. Blindfolded she couldn't see her tormentors but she could imagine their faces as they stood over her watching her agony. Or course, gagged there was no way she could express how much she might be suffering and she was utterly at Auda's mercy.

Vanessa had intimated that she'd suffered a similar treatment, so surely they knew how much someone could endure? Abruptly the waves of stinging heat rippling through her body ended and Vanessa lay gasping through her nostrils, struggling to recover her breath.

'A pleasing sight. How aroused is she?' Auda asked.

Zoe grunted through the leather gag as Vanessa fingered her aching sex.

'Very moist and her clit is heavily swollen. She'll come next time, I reckon.'

'Same setting then boss?' Basil asked.

'Same again.'

The sudden shock took Zoe by surprise. She arched her back and dragged her arms against the straps, groaning and biting down on the leather phallus in her mouth as the electricity washed through her aching body. After what seemed like an eternity but was probably just seconds the agonising sensation abruptly ended. Before she could recover herself, as she lay dazed and breathless, skilled female fingers stroked her aching clitoris and moaning helplessly Zoe felt herself quickly brought to a shuddering orgasm.

'See... she's getting off on it!' Vanessa laughed.

'Give her another taste then,' Auda ordered.

Zoe shook her head but her protest was ignored and her body was convulsing again as another wave of electricity poured through her. When it stopped, she lay dazed and exhausted. Again, her sex was stroked by Vanessa and to her disbelief and dismay she was quickly brought to another violent orgasm.

'Shall we give her another taste chief?'

'Yes, do it Basil! Please Auda! Make her writhe. Let's see how many times we can make her come!' Vanessa begged.

Zoe shook her head with what strength she had left. Gagged and blindfolded she had no other way of begging Auda to stop the cruel treatment.

'Give her another taste, Basil,' Auda announced.

Zoe gasped, writhing as a fresh jolt of electricity coursed through her aching sex and tethered, sweat soaked limbs. Please...no more... she begged, but gagged, her pleading went unheard and unheeded.

'There is no trace of him anywhere.'

'Well where the hell is his base?' Miles Fairfax demanded, his voice cracked with exasperation.

The young man shrugged apologetically and gestured to say that he didn't have a clue.

'How the hell can one of the most important Sheikhs in El-Saram just disappear, especially when half the rabble protesting on the streets are chanting his name?'

'Perhaps that's why he's disappeared? If the secret police or military knew where he was, they'd grab him. He's a ringleader in this trouble.'

'What about the two SES agents, those girls, where have they got to?' Miles asked, slumping down in his chair and reaching for the glass of lime and soda standing on his paper-strewn desk.

In the last twenty-four hours the discontent that had been simmering for months had suddenly erupted. Demonstrations in the capital had created a heightened sense of tension but more alarming were the unconfirmed reports that there was fighting in the more remote parts of the country. It seemed the desert nomad chieftains had gathered their forces and attacked some outlying military garrisons.

'They were last seen with that guide they hired. Dodgy looking character, some minor chieftain, or so he claims. I think they've gone down to the old harbour.'

'Right, there's nothing to be done here. I can't stand being stuck inside this place with the bloody air-conditioning broken. We might as well take a drive out and see what's going on.'

Half an hour later Miles and his assistant climbed out of their Daimler which they had parked alongside the BMW they recognised as the car the SES agents had hired. They found the two girls sitting on the quayside alongside their guide. All three were eating ice creams and gazing out over the shimmering water.

'So this is where you've been hard at work!' Miles said sarcastically.

'He's gone,' the blonde girl announced matter-of-factly.

'Who? Auda? How?' Miles took off his Panama hat and dragged his fingers through his hair. He could feel the perspiration pouring off him. His lightweight cotton suit was fine for indoors, but out here in the heat he could feel it clinging to him. It was impossibly hot yet somehow the Arab, Fiezal, looked cool and calm in his traditional flowing robes and headdress. The girls looked pretty relaxed too, but then their work clothes seemed more minimalist and he found it difficult to avoid gazing at them. To his embarrassment he felt his cock stiffening and faced with what two such deliciously fit and alluring female bodies were wearing, it was hardly surprising, he consoled himself.

The blonde girl had on a mid-thigh length denim skirt that was slashed up one leg to her hip and a denim shirt whose sleeves were rolled back and which was knotted at her waist and only half buttoned up, so her black lace bra was easily discernible. The dark haired girl had her height accentuated by high-heeled boots and had an olive green mini skirt and a tight white crop-top that left her taut stomach exposed.

'You should be careful in this country with how you dress, girls,' Miles cautioned, seeing that they both had become aware of how he was staring at them.

'Our guide has four armed men at the end of the quay and as long as we're with him there's absolutely no problem. Besides which, we do know how to look after ourselves,' answered the blonde girl tersely.

'I'm sure that's what Miss Farquerson thought. So did you say that you thought that Auda had gone? Do you mean as in left the country? I don't see how, we've been watching the airport and the border crossings. Unless he trekked across the desert...' Miles suggested.
