along. Also, it might be prudent to be there if something untoward occurred. And there was always the chance that she herself might learn something new. Harriet wasn’t averse to a bit of voyeurism every now and then.
There was no way of knowing how long Rachel would take to react to her fantasy, if indeed she reacted at all. It might still come to nothing. Not every woman was able to bring herself to climax without the use of her hands, but some could do so after a bit of training.
Rachel lay quietly for almost a quarter of an hour. Harriet thought she might have gone to sleep, but she hadn’t. Her first sign of life was to try escaping from her straitjacket. Harriet could see her pulling against the straps that bound her hands and arms against her body. In her imagination she could almost hear the creak of the leather as the young woman tugged and jerked against her bonds. Next Rachel tried the straps that bound her legs together, though even if she had somehow managed to loosen them she would be no further forward. Harriet knew there was no escape, but Rachel had never been so completely immobilised before, and she had to discover for herself what it meant to be in bondage. For a moment Harriet regretted not having strapped Rachel to the bed, but that could be done later if the young student liked the first lesson.
After only a brief struggle Rachel appeared to give up the idea of escape, lying quietly once again. The only result of her efforts was a slightly elevated rate of breathing and a flushed face. When she moved again, it was to turn herself on to her side. This was accomplished after several attempts – she obviously wasn’t used to levering herself about without the use of her arms and legs. Each time she got halfway there she would lose her balance and roll on to her back again. Finally she succeeded, and lay facing in Harriet’s direction. She bent her legs at the knees to prevent herself rolling back again. First lesson learnt, Harriet thought. Rachel’s face was more flushed than before, and Harriet guessed that her struggles had caused the plugs to move inside her vagina and anus. Rachel didn’t appear distressed by that.
Her next action showed that she was learning the second lesson. As Harriet watched, the young woman began a deliberate series of thrusts with her hips which were obviously intended to move the two plugs about. She began slowly, experimenting to see what produced the best results. Harriet watched her breathing quicken and her face become flushed once more. Rachel began to move faster, jerking her hips backward and forward. Abruptly she lost her balance and rolled over on to her back. Harriet could see her frustration as she struggled on to her side once more.
This time Rachel was more careful about her movements, but she didn’t seem to be able to arouse herself as before. She tried again. Her hips moved rhythmically as she felt her two plugs. This time when she lost her balance she rolled over on to her stomach, where she made a discovery. In this position she could grind her hips against the bed. She did so, more and more energetically, and it soon became clear to Harriet that the young woman was an untaught auto-erotic. And an explosive one. Rachel’s movements became more rapid as she discovered what the dildoes and the rubber pad over her vulva were doing to her.
Harriet regretted not having installed a microphone and speaker so that she could listen as well as look. Rachel looked as if she was becoming frantic. She twisted her head from side to side, and whenever she was facing in the right direction Harriet could see her mouth working. Every so often she could hear a faint cry from the other room, but most of the evidence of Rachel’s arousal was visual. She jerked and bucked against the mattress, then suddenly became rigid, apparently in surprise. She was facing Harriet at that moment, and she saw that the young woman was on the verge of a climax.
The next moment she
