For as long as she could remember, since being a little girl, Della had been known as the "Rubber Girl." Her joints and ligaments had made her the most flexible and supple girl in the class at school, in the troupe at Brownies, in the athletic team at college. And she was a good athlete; swimming, running and floor-gymnastics. In the common parlance, or slang, in her home town and area, it was said that she was "double jointed." That made no sense, of course, but everyone there knew what it meant. From an early age, she had been something of an exhibitionist; putting her foot behind her head, lying on her belly and bringing her feet forwards to rest on her shoulders.
Medically, Adele to give her proper name, was classified with hyper-mobility syndrome and her parents had been advised to ensure that he remained as fit and active as possible. And she certainly had done that. But also she had been cocooned somewhat by her family to prevent over-popularity turning into exploitation or worse. As a result, when Della entered employment at the age of 18 years, she was [shall we say] not fully socialised. She joined a fitness-physiotherapy-osteopathy-weight control company: as a trainee physiotherapist. Of course, she was surrounded by fit and active athletic people like herself, all of whom enjoyed pushing their bodes to the limit in one way or another. But none had her flexibility and she quickly acquired fame for that attribute.
Her first boyfriend was another job-starter of 18, in the same company, who seemed out of his depth with such a fit and athletic girl. Putting it bluntly, he didn't know how to treat a lady; any lady, never mind Della. And Della was typical of the athletic build of such girls: hardly any breasts nor flesh around her hips or derriere. There was "...nothing for me to get hold of," he said at the end. She was left wondering what all this sexual excitement was meant to be; about which she'd heard so much. She was penetrated whenever they "made love" but she got little sensation and no satisfaction. Definitely not any overwhelming pleasure that could be called an orgasm. And he seemed to be in a hurry to shoot his load into her and then either to fall asleep or else go out for a pint of beer. Their friendship could have been the archetypal sensuality discovery expedition, but it turned into one constant frustration for both of them.
Then Della met a slightly-older male physio known as Jimbo; properly James, of course. Jimbo made his living by performing physiotherapy on men clients and women. He had a very clear and detailed knowledge of human anatomy. And he was intrigued, not to say captivated, by Della's skeletal flexibility. He sought her out at any social event, and in the company restaurant, and offered her rides in his car back to her lodgings, and to weekend parties. His captivation was matched by Della's sense of specialness. Of course, these feelings developed and transformed into lust; or maybe love, but who can tell?
Their first sex session in a proper bedroom, in a hotel, was a revelation to Della. Jimbo had the knowledge to play on her clitoris with his hands and his mouth and Della reached an orgasm for the first time. He lay between her splayed-out legs and pressed his face to her labia and inserted his tongue into her until she was running with excitement-juice. Then he commenced licking rhythmically on her clitoris whilst reached forward to hold her little buds of breasts. He seemed to be in no hurry, except to please her.
Della was surprised and delighted to experience pleasure from her tiny nipples, as well as from the tongue pushing her towards a climax. And the head between her thighs gave her a feeling of power whilst also under the influence of this clever man. When her orgasm began to build, she was alarmed at first; the sensation started high inside her under her breast bone. Then it travelled to her groin and finally came to a crashing climax inside the labia and the opening into her body. Somewhere up inside, behind her pubic bone, beyond the reach of his tongue, somewhere mysterious. She collapse into a sort-of trance, wondering if she would ever again receive such treatment and gain such a sense of relief after the explosion.
In her half-conscious state, Della was always pleased to have Jimbo enter her and bring himself to climax also. Sometimes he was gentle and other times she thought, "He's going to shag me to death." She learned to enjoy every aspect of their sex times and Jimbo was careful always to bring her to orgasm. She learned to manage her orgasms so that they built through delay, and sometimes coincided with a massive squirt from her bladder; which excited Jimbo a great deal. He said it proved she was a full and true woman. She liked that idea a lot, and that description of herself.
Over the next weeks and months, Della and Jimbo took this pleasure many times. It didn't pall or diminish but Jimbo wanted more, she could tell. He placed her differently sometimes and she could sense his desire to bend her into new positions: not just lying flat with her legs wide open.
Then one evening, without warning, he said to her softly, "Just lift your knees and bring them near your shoulders." She did so, and Jimbo took hold of her hands and brought them through the space between her thighs.
