Being a guy with time on his hands and temporarily living alone I took on a voluntary evening job at our local community hall. It didn't involve much and it was a chance to meet people. I opened the place up in the evenings, stayed around when it was used and tidied and locked up afterwards. A number of groups met there in the evenings, such as the local residents association, a bridge club and a wine tasting club. They were interesting people. But what I looked forward to most of all was the women's exercise class.
The class consisted of about a dozen women in a mix ranging from slim sexy girls in their twenties right through to big bottomed, big boobed middle aged housewives. I had a tiny room which doubled as a cleaners' cupboard I could sit in. But when the exercise class met I watched through the door which they always left ajar for ventilation and my eyes were constantly on the woman who ran the class, Tanya.
Tanya was a beauty in her late twenties, about ten years younger than me, with dark hair down to her shoulders which she normally tied in a pony tail for the class. As you'd expect she had a superb lithe figure with big firm breasts, a cheeky round well tuned looking bottom and mile long mans' dream legs. Tanya usually wore a figure clinging shiny blue leotard low cut between her breasts, high cut at her hips and with her legs in sheer tan coloured nylons. Perhaps I've got some kind of fetish but I don't think any garment could have emphasised Tanya's female curves more sensuously as she arched and thrust her young body and spread her long legs during her exercise routine than that leotard.
One evening, as usual I was ogling Tanya during her exercise class. She was in her leotard but in my lustful eyes and mind she was nude, showing off the big firm breasts, smooth round bottom and the bush between her legs which I'd imagined so many times as my penis strained for her in my masturbation fantasies.
As Tanya took her class through its exercise routine I watched her spread her long nylon clad legs impossibly wide in splits with her leotard bulging invitingly over her sex mound between her thighs. I ogled her as she bobbed smoothly and rhythmically up and down in wide kneed squats, imagining her astride me like that with her breasts bouncing above me as she rode my hard up rod. As she lay back on her exercise mat with her legs folded up I was on top of her between her spread thighs feeling her naked body under mine, her legs wrapped over me and her vagina tight, smooth and warm around my hard up cock.
My lustful eyes were almost permanently on the thin blue gusset strip of her leotard nestling in the valley between her bum cheeks and running down between her legs. That so erotic strip of blue cloth always led my gaze irresistibly down between her nylon clad legs to the bulge of her leotard over her mound. I strained my eyes to catch any glimpse of a dimpled cameltoe outline of her vagina slit.
Then it happened. Tanya was bent over a chair with her legs wide and with her bottom toward me sensuously swinging as she rocked her hips to the beat of the music in an exercise routine with her ladies following her movements. My eyes were locked on Tanya's hypnotically swaying bum cheeks, her nylon clad legs and as always that thin gusset strip of her leotard.
Suddenly and unexpectedly Tanya glanced straight at me over her shoulder. Our eyes met and she gave me a lewd grin. Without disturbing her rhythm, and I'm sure without any of her ladies noticing, Tanya's hand slid down her leotard clad front and between her spread legs till her fingers peeped out between her bum cheeks as she fingered her pussy. She ran her fingertips smoothly back and forth along the line of her vagina slit through her leotard. Though she only stroked her mound for a moment I've watched women masturbate enough times to know what that gesture meant, and to guess at what she was telling me!
I couldn't keep my eyes off Tanya after that. My penis rose hard and wouldn't stay down. Finally at the end of the class Tanya's leotard clad body disappeared into her tracksuit and she and the ladies departed leaving me alone in the building.
I was in the hall tidying up when I heard a noise behind me. I turned and there was Tanya back again. She was minus her tracksuit and trainers, just in her blue leotard and nylons and in the slightly high heeled shoes she wore for driving her car, and with her dark hair still in her pony tail. She was standing slightly spread legged, her hips thrust forward, her arms down her sides with her hands on her bum cheeks, and gently but sensuously rocking her hips.
"Did you like watching me fingering my pussy?" Tanya said softly. "I could all but feel your hand between my legs."
As I was standing there staring at Tanya amazed she bent over that same chair with her leotard clad bottom toward me and spread her nylon clad legs wide.
"Go on! Touch me ... if you want!" Tanya said softly but with excitement in her voice, and as she spoke she wiggled her bottom at me and fingered herself between her legs stroking her mound like she had before.
I wanted! My hands started on her legs. Perhaps I'm a fetishist, but I find the sight and feel of women's sheer nylon clad legs every bit as exciting as bare female flesh for penis straining arousal. I followed the hem of her leotard slowly across her bum cheeks with my fingertips and fondled the curves of her firm round bottom through the thin lycra. Her smooth taut leotard deliciously emphasised the feel of her rounded curves.
Then that so erotic gusset! I ran my fingertips slowly down the valley between her bum cheeks. In a crowning moment of achievement my fingers reached that thin gusset between her spread legs I'd lusted for so much. It had always filled my mind in my moment of orgasm when I masturbated thinking of Tanya, even when she was performing completely nude for me in my masturbation fantasies. Now my hand was on that gusset, brushing against her nylon clad inner thighs, cupped over the soft warm bulge of her mound! I felt a sense of conquest like that moment a guy never forgets when he gets his hand under a girl's skirt for the first ever time, slides his hand up her bare thigh and finds her thin cotton panties tight over her bottom.
My fingers gently stroked and explored the bulge of Tanya's sex mound through the thin Lycra, finding and following the dimpled line of her vagina slit. Tanya whimpered and trembled with excitement and she spread her legs even wider for my exploring hand as I played with and aroused her pussy. When she stood up after a few minutes of enjoying my hand between her legs her cameltoe was prominent and the bulge of her leotard over her mound where I'd been fingering her was moist.
"You were imagining me nude as you watched me weren't you?" Tanya said, grinning at me. "Go on, undress me if you want to see me nude for real."
I hardly needed to be asked! I started by pulling the shoulder straps of her leotard down. She wasn't wearing a bra underneath and her breasts bounced out, every bit as big, round and firm and smooth and warm in my hands as I'd imagined them to be in my masturbation fantasies, with her nipples up like little deep red corks with arousal. I couldn't keep my hands off her breasts and as I played with them Tanya slipped her leotard down and off then kicked it aside.
That left her just in tan tights with a tiny white thong underneath. Like every guy I prefer stockings to tights, but as I ran my hands over the whole length of her mile long soft smooth legs as I slipped her tights off her I certainly wasn't complaining. Her thong was the briefest I've ever seen, just a thin white strap nestling in her bum crack and a tiny white triangle of cloth at the front just big enough to cover her mound and showing the shadow of her cunt hair beneath. I pulled her thong down round her thighs to reveal a neat patch of almost black pubic hair around her slit.
Tanya let her thong drop round her ankles, kicked it aside and spread her legs wide. I cupped my hand over her pussy mound and she gasped and moaned with sex pleasure as I gently stroked her vagina lips, ruffled her cunt hair and slipped a finger into her juice sodden love slit.
Suddenly Tanya stepped back from me. Holding the chair and standing on one leg she smoothly swung her other leg up till it was pointing almost vertically straight up and took hold of her ankle. I believe that pose is a stretch gymnasts and ballerinas call a leg hold. It got her naked legs every bit as wide as when I'd watched her do the splits, except now vertically, and it pulled her pubic hair ringed vagina lips open so wide her juice glistening inner labia poked out.
"Is that a pose you were imagining seeing me in nude?" Tanya said with a grin.
In my masturbation fantasies I'd seen Tanya nude and shagged her in poses she'd hardly believe a woman could get her body into but even in my kinkiest dreams I'd never imagined her like that! I didn't tell her though.
