I began by having Susan indulge her body in a soothing, warm bath, during which I carefully removed all the stubble from the tender skin of her armpits and at the tops of her inner thighs. Thus, by the time that she emerged, her entire body was warm and pink, and two of its most sensitive surfaces were thoroughly exposed and vulnerable.
Once I had toweled her dry, I had Susan lie with her back on a cushion which I had placed on the floor next to the wall. When her rump was a few inches from the wall, I asked her to raise her legs so that they formed a ``V'' and her heels rested against the wall. After her legs were in place, I asked her to rest her arms along the sides her head, and, as a result, Susan's torso was now presented to me in a most attractive way. Obviously, her position entailed some stretching of her entire body, but, because her heels were supported by the wall, only her groin was subjected to anything which could be described as real strain. In fact, even there it was merely the steady pull of gravity on the tendons in her thighs which produced a mild and easily tolerated tension.
When Susan had assumed this pose, I told her that she was allowed to move her body in any way which did not diminish the tension in her thighs. Thus, although she was permitted to spread her legs further apart, she was to do nothing which brought them closer together. Having explained these basic ground rules, I sat myself down next to her hips and began to slowly massage and tease the exquisitely soft, recently shaved skin at the juncture of her thighs. Not surprisingly, she found my activity simultaneously soothing and exciting, and in response she was increasingly willing to let gravity pull her legs further apart as her muscles slowly accommodated themselves to the stretching to which they were being subjected. Thus, after about ten minutes, the angle between her thighs had increased so much that her legs were nearly parallel to the floor and the musculature on their inner sides had become prominent.
However, it was not until I turned my attention to the tender folds of flesh which are the gates to her vagina that Susan abandoned all concern for her already stressed tendons and exacerbated their plight by lifting her pelvis in an attempt to increase the sexual pleasure my fingers were eliciting from her body. Needless to say, the flesh on which I was working was well lubricated by her own secretions, and her position left this most intimate part of her anatomy completely open to my ministrations. Thus, once I had begun this intense stimulation, it took just a few minutes to bring Susan to the brink of orgasm. However, orgasm was not what I wanted her to experience at this point. Instead, when I saw that further stimulation would push her over the threshold, I withdrew my hand and told her that I was going to make her stay where she was while her own copious secretions dried and, as a consequence, sealed close the entrance to her clitoris and its environs.
