As Kathy obeyed and her tongue and lips got busy in Kerri's sex, part of her mind was aware of the intensely humiliating position she was in: the only thing she could see were the curves of her friend's buttocks, and only when Kerri lifted herself up a little; when she lowered her pussy, which she did often to gain more pleasure from Kathy's hard-working mouth, Kathy's eyes were almost covered by her ass-cheeks and her nose was pressed into the crevice between them, very close to Kerri's anus (since Kerri kept herself very clean, the odour there, while not exactly pleasant, was hardly offensive). Yet she found herself, as usual, loving the very humiliation itself, this time precisely because she was helplessly restrained and had virtually no choice but to do what Glen asked. Another part of her was even more aware of other things: the taste and smell of Kerri's sexual arousal, similar to Kathy's own yet distinctly different; her own rapidly building arousal, mainly due to what Glen's knowing hands were already doing... on her breasts, her nipples, the sensitive flesh on her belly and the inside of her thighs and, of course, on and in her pussy; and, by no means least important, the knowledge that she was providing pleasure to her husband whom she loved so much.

For Kerri, things were different but no less interesting. She found that she could no more pretend it was a man eating her out than escape the restraints she was in; instead, she was intensely aware that it was a woman's mouth on and in her sex (after all, she could see a woman's naked body lying restrained on the bed under her, and it could only be that body's head between her spread thighs); also, there seemed to be something quite different, in the way Kathy used her lips and teeth and tongue, from any of the men - skilled or otherwise - who had given her head... and she'd had her share, or more! Then there was the knowledge that it was not just any woman, but her close friend and confidante, who was willing to take part in what she felt sure was the very first experience of girl-girl sex for both of them, and to help Kerri herself to what promised to be an utterly mind-blowing orgasm. Nor could she ignore the fact that she, as well as Kathy, was helplessly and inescapably restrained and had been manipulated into her current 'predicament' at least partly by the dominating personality and desires of her best friend's husband.

All the above contributed to the sheer intensity of the climax that swept through Kerri within a few minutes. That it came so quickly, she thought as she came close to losing consciousness, was also due to the long series of repeated arousal and 'easing down' that Glen's hands had subjected her to in the cell earlier... the continual caresses, during dinner and later... the erotic game of fellatio they'd played... and, last but not least, the stimulation of the video they'd watched.

For Glen, the reality of his long-held fantasy went far beyond his wildest dreams. He watched in utter fascination, even awe, as Kerri gasped and howled and shook and, finally, nearly deafened him with her shrill scream of ecstasy. At last she started to 'come down'; but Kathy, who had 'eased off' to allow her friend's orgasm to run its course, suddenly began working again with her lips and tongue. In seconds Kerri had a second climax; Glen thought it might have been as intense as the first, but she seemed too spent to do more than pant rapidly and quiver and moan, in hardly more than a whisper, "Ooooooh, godddd... yes... yesyesyesyesyes... oooooooooh yessssssssss!" And in the middle of this Kathy climaxed, too... to Glen's surprise, who was sure he hadn't aroused her to anywhere near that point! Was it possible, he wondered, that she'd been so turned on by the very act of bringing her friend to two orgasms?

By now Kerri had gone completely limp and was threatening to suffocate Kathy under her crotch and buttocks, so Glen had to raise the chain to lift her up a little. He waited until Kathy's mild but clearly very pleasant climax was spent, using his hands gently on her breasts and belly and pussy to help her 'come down'; then he went to the side of the bed and helped Kerri into a more comfortable position - sitting back on her heels with her thighs hugging the sides of Kathy's head, and her wrists held just over her head. "Nod if you'd like a drink of water," he asked with a smile; she nodded and he fetched the sports drink bottle kept in the bathroom; the water wasn't very cold, but both girls sucked greedily at the bottle... and obviously appreciated him wiping down their sweaty bodies with a warm damp cloth.
