Beside me, I could feel Pamela and Maria bristling, and with good cause. Their admiration was tinged by fear: what they were viewing on the screen was due to be inflicted on them too, their forfeit for having lost the challenge. The ferocity of Carina's attack was startling and I could well understand their discomfort.

"Hmm," I said wickedly. "Bet you wish you'd tried a bit harder now." Pamela tried to laugh off my remark, but I could tell she was worried. Maria was beyond speech, her eyes taking in the scene on the cam incredulously.

Finally, Carina finished her beating. She brushed her hand across her brow, removing the sweat, and turned round to the cam, giving us a thumbs-up. Returning to Adam, she kicked him and he rose from the settee, standing to attention in front of her. We could see his little dick, half erect with the excitement of his ordeal and quivering in anticipation. Carina took his place on the settee and stretched herself languidly. She raised her foot and presumably gave some order, as Adam dropped to his knees, his reddened arse pointing towards us, and pressed his face against the sole of her raised foot. As Carina manoeuvred him to the side, giving us a clear view of the action, he began to lick and suck her foot assiduously, drawing her stocking-clad toes into his mouth and allowing himself to be foot-fucked. Carina pressed her other foot against his nose and face, squashing it as she pressed deeper and deeper into his mouth. It was an engrossing scene and even Pamela and Maria began to relax, their minds taken, by the vision before them, from their own impending punishment.

After a few minutes of loving attention to her feet, Carina pushed him away and sat up on the settee. Beckoning to him, she grabbed his still erect dick and squeezed it. Poor chap: he no doubt thought that, after all the punishment, his reward was coming. As if. Carina started to wank him and we could see his dick harden and grow. He was impressively apportioned, it had to be said: far more extensively equipped than his colleague Stephen, whose little member had made such a mess of my desk a few days before. He raised his head in delight but, alas, his joy was shortlived. With a start, he doubled up in pain as Carina's hand slipped from his shaft to his balls, squeezing hard. As we watched, we saw her indicate towards us and Adam's look followed her pointing hand.

"She's telling him about the cam," said Pamela, laughing.

Still gripping his balls, Carina pointed again towards us, and it was clear that she was, indeed, explaining to the inept salesman that he had been caught on camera. She walked him towards the cam and squeezed him again, forcing his legs to buckle until he ended up on his knees, with his his puzzled face appearing in the frame of the cam.

"hi," she typed."

"hi," I replied.

"say hello to adam."

"hello adam."

Adam's face was contorted with horror. His eyes were wide, his mouth open, and he was blinking continuously. I knew what he must be thinking: the poor boy, he must have thought his gods were with him as Carina began to chat him up; and what young man would refuse a touch of kinky stuff if he thought there was going to be some old-fashioned fucking at the end of it? Somewhere around the fourth or fifth swat on his backside he probably realised he was involved in something more sinister than he understood, but still he went through with it: no-one will ever know, he would have thought, and I'm still going to be able to fuck her at the end. Thus his thought processes would have run. But now, he could sense his chances of a fuck were nil, and even worse it was clear that somebody had been watching the entire, shameful experience. Oh, the misery, the humiliation which would be humming through his brain as he watched the PC screen and the hideous conversation unfolded.

"tell adam who's watching," Carina typed.

"adam, this is harriet here. senior manager. i liked what i saw," I replied. Adam began to shake his head, still blinking.

Pamela took my place. "hello adam. pamela here. nice ass, little boy. very red, now 3; loved the show." Adam closed his eyes and shook his head again. He looked as though he were about to be sick.

Maria took over the keyboard and typed slowly. "hi adam maria here, cleaner girl you ogle allday. got what you deserve yes?"

Adam buried his head in his hands. His world was unravelling before him. I knew he would be replaying the recent events in his mind: in retrospect, his voluntary submission to such a spectacular punishment would be embarrassing enough, but now he had the additional humiliation of knowing he had been set up and his entire performance had been witnessed by three women from work. What misery must have percolated through his brain as he tried to understand how he had found himself in this situation. He was jolted from his self-pity, presumably by another judicious squeeze of his testicles, and stared at the screen once more, his face a vision of dejection.

"Hello," he typed. "Thank you for watching." I laughed. Even in his torment he wrote formally, using capital letters. There was a pause as he looked away from the screen, towards Carina: he was clearly being given his instructions. "My body is ready for you to use," he continued. He closed his eyes again, unable to look at the words he had written.

"glad to hear it little man," I replied. There was a long pause, while the screen was filled with the increasingly anguished face of Adam. A momentary blur of activity washed over the screen, causing everything to disappear into a Jackson Pollock style melee before Adam's face appeared again, slightly reddened where he had evidently been slapped by an impatient Carina. On our screen, the next message appeared, and we could understand his reluctance to write it.

"I want you to put my cock in a cage please."

Carina, Carina, I thought. Face of a minx, mind of a tyrant. Well done, my pretty one, well done.
