It was on the Thursday evening that Jade and Eva went to the keep fit class in the gym. Neither of them expected to have anywhere near as much fun as at the swimming pool but the both realised that they did need the exercise.
Jade selected a pink leotard and Eva a yellow one and they walked to the gym wearing dresses that were so short that their butts were only just covered and their slits weren't.
It was a male instructor, Don Little, that greeted them and he gave no indications that he'd seen their slits as they approached. Don Little looked to be in his mid to late twenties and when they said that they were there for the keep fit class he told them that they had made a good choice then went on to explain that it was a general fitness class covering exercises and other moves from quite a number of disciplines and is designed to improve general fitness for everyone but some of the exercises were specifically beneficial to women.
"I will push you hard but please stop if you think that it is too much for your body. Just about all the class will be students like yourself so we shouldn't have any real problems. Right, the ladies changing room is over there and I'll see you in the gym."
Both girls were a bit apprehensive, neither of them having had any serious exercise since they did PE at school.
In the changing room they saw a few other girls in various states of undress. Most were changing into leotards, some with shorts over or under them. Most of the leotards were of the thong variety and a couple of girls left the changing room with nothing under or over their thong leotards. That pleased Eva as they wouldn't look that out of place. One girl was wearing a polo shirt and a school type PE skirt and Eva wondered if she was wearing anything under it.
Eva and Jade stripped naked then put their leotards on. Both girls struggled to keep the 2 centimetre wide crotch covering strips over their labia as it kept opening them up and disappearing out of sight, Eva giggling as the material went to one side of her clit and made it stick out even more than normal.
They looked at themselves in the mirrors and saw that the difference in colour of their areolas and nipples was very obvious as the mesh moulded to their breasts.
Both girls were smiling as the walked out of the changing room and into the gym where they saw various items of gym equipment scattered around and a group of around 8 girls and 4 boys standing around chatting and waiting for the instructor to start the session.
As they approached the group they saw 2 girls and 1 boy do a double take when they saw them.
Both Eva and Jade said hello and they got a response from 3 or 4 of them before Don Little came in and blew his whistle then told everyone to form 2 lines in front of him. As Eva and Jade lined up on the back row Eva thought about her pussy and realised that the crotch material of her thong had disappeared between her labia to one side of her clit.
"Fuck it, I don't care." Eva thought as she listened to what Don Little was saying something about loosening up.
They did some simple arm and leg stretches then went on to twisting their torsos. All basic and simple so far but when they moved on to to the sort of exercised that they used to do in PE lessons they were down on their hands and knees and their backs with their legs going all over the place. The thing was, if, and when, the girl and the young man in front of Eva, and probably Jade as well, got the impression that she had nothing on between the top of her butt crack and the top of her slit, and they could see her clit that looked larger than normal because of the pressure that the material of the leotard was putting on the side of it.
The other thing was that Don Little was walking around telling people to try a bit harder and when he got to Eva he stopped and stared at her apparently uncovered pussy. For a few seconds, as he stared, he went silent then continued whatever it was that he was saying.
For the next 10 or so minutes he had everyone doing leg stretching exercises that involved their legs being stretched wide apart. One such exercise involved 2 people sat opposite each other with their legs straight and spread wide, one pair of feet pushing the other persons feet further apart being helped by the couple holding each others wrists and pulling.
When Don Little partnered the class both Eva and Jade got partnered with a young man which please both Eva and Jade, and probably both young men. Eva wondered if he'd done that on purpose.
That was the first of many exercises and activities involving 2 people and Don Little always partnered Jade and Eva with one of the young men. By the time the class ended all 4 young men had had a great view of both girls pussies. They'd also had plenty of time to stare at their tits through the see-through mesh.
Don Little got his share of the scenery because he always seemed to be near one of the girls when their legs were spread wide.
Leg stretching exercises weren't the only things that they did, Don Little had them running, vaulting, step-ups, sit-ups, squats and many more. One activity that Eva like was rope climbing, not so much the climbing as it made her arms ache but the sliding down.
As the thick rope slid passed her pussy it made her cum and she had to feign being out of breath and bent over putting her hands on her knees to get her breath back. Don Little and one of the young men were behind her and she wondered if they could see her pussy convulsions. They would definitely have seen how wet her pussy was and the odd body jerk that she couldn't stop.
By the time the hour was over most of the people there were shattered and they all headed to the changing rooms for showers. Eva and Jade however just lay on the floor in the gym relaxing and talking about all the men looking at them. They didn't realise how much time had passed until Don Little asked them to drop the latch on their way out. He'd been putting the equipment away then gone and checked that the others had left before going back to the gym and asking them.
Eva apologised and said that they'd only be a few minutes and they got up and followed Don Little to the door. As he left and was walking away Eva dropped the latch but with her and Jade still inside. As she turned to go back to the gym she took her leotard off then walked straight to the big rope.
She unhooked it from the wall then up she climbed and slowly descended, letting the rope rub against her pussy as she went. She orgasmed just before she let go and dropped to the floor, fortunately her feet being only half a metre from the floor when her hands lost their grip.
"Woah there girl," Jade said as she took off her leotard and climbed the rope. "I want a piece of that."
Both girls repeated that exercise until their arms couldn't pull them up anymore.
The rope climbing was the only activity that gave them any sexual pleasure without any men there to watch them so the headed to the showers and helped each other get rid of the sweat from their bodies.
What they had expected to be just exercise ended up being a very pleasure time and as they happily waked back to their flat they played a game of pull up the other girls skirts and they gave a few people a very pleasant surprise.
