Nick stepped forward. He had a plastic bottle of water in his hands. He pushed its nozzle between her lips and made her drink several gulps down. The pure water washed the stinging sour taste of vomit from her mouth and settled her stomach. She began to feel a little less queasy.

'This isn't me going soft on you,' he told her. 'You see we've got to keep you awake and alert for the rest of the day while our client has her revenge. Can't have you passing out just because you're short of water and get lightheaded. Now you can pass out from pain, that'll be okay...'

Jemima whimpered as she felt the last shreds of her self-discipline slipping away. 'No... please...' she sobbed, and then she began to scream. 'Help... help... guhhh!'

Nick had rammed something into her mouth again. This time it was a large black rubber plug fitted to a thick rubber bar like a horse's bit which he jammed between her teeth. It was held in place by rings on its ends which pressed against her cheeks, and a web of straps that went over the bridge of her nose and under her chin and up over the crown of head and over and under her ears, and which all fastened at the back of her neck. The plug drove her tongue down and the bar stretched her lips wide, stifling her protests, so she could only peer mutely at him over the straps that divided about the bridge of her nose and went down across her cheeks. They pressed tight against her flesh, making it bulge up about them.

'I like it when a woman's face is properly bound up like this,' Nick said as he pulled the straps tight. 'They can't speak or show how they feel. It just leaves their eyes rolling about, all silently desperate and pleading.'

'A regular work of art,' Jack agreed, returning to them with a bucket, a grease gun and a length of soft rubber hose. He admired Jemima's face which was now divided at all angles by the tight black strap bands. 'You are the Picasso of bondage, Nick. Now, what shall we do to warm her up?'

'I don't think we should mark her skin yet. Our client will want to do that. But a double screwing would certainly do it.'

Jemima moaned and shook her head violently. They ignored her.

'Yeah, I think that would work out right. But surely a few slaps wouldn't matter...' He swung his hand and smacked it into Jemima's bottom with a crisp crack and she jerked and gave a stifled whimper of pain.

'No, of course a few slaps won't hurt...' Nick agreed, slapping Jemima's breasts briskly so they stung and shivered. 'Do you want to have her up her bumhole?'

Jemima froze, her eyes growing wide in horror. What?

'Yep, I think I'll have fun up there. She's got a great backside. Must be all those trips to the gym. I just need to clean it out...'

Ignoring Jemima's desperate struggles, he put the bucket between her legs and then plugged the short hose over the nozzle of the big hosepipe. Then he pushed the hose into her desperately clenching anus and slid it up into her rectum. He turned the hose on and Jemima shrieked as a jet of cold water emptied her entrails out like an enema, the wastes gushing into the bucket.

When Jack was done, he wiped her bottom clean with an old cloth and put the bucket and hose aside. Then he pushed the grease gun up her rear to squirt petroleum jelly into her rectum. She felt its slippery substance begin to seep out of her anus.

Jack and Nick pulled open the flies of their coveralls, freeing straining cock shafts that bobbed stiffly upright like self-erecting flagpoles. Jemima's gaze fastened upon them in sick horror. They were going to push them up inside her and there was nothing she could do to stop them.

Jack positioned himself behind her and Nick in front, so that she had to look into his lurid rubber devil mask. She felt the flowing hair of Jack's mask brushing her shoulders as he moved closer, holding onto her hips and rubbing the head of his penis up and down the cleft of her buttocks. Then it found her tight anal sphincter now slippery with grease and began butting into it. At the same time Nick pulled himself closer to her until her breasts ground against his chest. She felt his penis head rubbing through her cleft until it found the mouth of her vagina. Then the two of them thrust into her together: skewering her between them on their spears of flesh, the power of the double penetration lifting her almost off the ground with a clink and jerk of chain.

She yelped as she felt their cocks seeming to meet within her. She was perfectly impaled upon them both, feeling their living shafts claiming use of what had been the private voids within her body. She had been invaded and completely mastered.

'Can we bruise her a little inside?' Jack sighed.

'We can do that,' Nick said. 'It won't show...'

With her sandwiched between them they began to pump into her rectum and vagina with deep regular strokes, savouring her total helplessness as they ground her body against theirs, thudding into her and driving the breath out of her as she fluttered feebly in their grasp. And as predicted her tears began to flow, burning her eyes and rolling down her cheeks over the straps of her gag bridle as she sobbed and whimpered at the depths of her humiliation.

It could not possibly get any worse than this, she thought wildly.

And then it did...
