Maggie & Jim Have Fun at the Gym

A new story although I wrote it a while ago. Enjoy!

In the months that followed Maggie and Jim's first sexual encounter they regularly found time to be with one another. Not only did they enjoy the fucking, but they also loved to play. It was during a playful sex session that Maggie first suggested that Jim might enjoy working on his muscles. Although he was a part time life guard, he'd never really bothered with building his body, but with his sister's encouragement Jim was only too happy to sign up at the local gym. He was to discover that it was one of the best decisions of his life so far!

Jim had to undergo the usual assessments before he could start to use the machines and weights. It was while he was waiting for this assessment that he first noticed the positive advantages of working out in a gym, because there before him was a spectacularly beautiful girl. She was just about to start work on a leg enhancing weight machine. As he watched, she leaned forward to adjust the weights, and as she did so, her vest top fell open to reveal a delicious cleavage. He guessed that her tits were about 36 B, and they swung enticingly before Jim's eyes. As she straightened up Jim took in the rest of her body; a narrow waist, blonde hair pulled back to keep it out of her face, while she worked out, the longest legs he could remember, and the most beautiful eyes. He found it difficult to take his eyes off this goddess, but the instructor had arrived, and she wanted to start his assessment.

This wasn't going to take much persuasion either! Jim couldn't believe his luck. The girl who was going to carry out his assessment was also gorgeous. He eyed her up and down as casually as he could. Jenny, her name badge informed him, had raven black hair and was about 5'6. She was dressed in the usual gym gear of tight lycra shorts, which displayed her every outline, including the crack of her pussy lips. Her top was zipped up the front, but she hadn't done it up all the way and when she leaned forward, to pick up some paperwork, Jim could see her sports bra beneath. She obviously needed this particular item of under-wear as her breasts were quite large.

Jenny beckoned for Jim to follow her into a small assessment room. He took a final look at the girl on the weights machine, noting with satisfaction that she was looking up as he glanced at her. She smiled and returned to concentrating on the job in hand.

The little assessment room had a desk and an exercise bike to one side and to Jim's surprise a low bed on the other.

Jenny saw his look and laughed, 'We use this room for our over enthusiastic clients to lie down on when they push themselves too far. Don't worry its not part of the fitness assessment.'

Jim grinned in return. 'That's a shame; I was hoping it might be. I thought perhaps you might need to see how much stamina I've got.'

Jenny blushed and quickly shuffled through some papers.

'I'm sorry Jenny, I shouldn't have embarrassed you' Jim quickly responded.

She looked up and smiled 'Don't worry, I don't really mind. It just took me by surprise. Actually I quite like the idea!'

This time Jim laughed 'What do you mean?'

Jenny went redder still '... well you know, I see all sorts of real hunks and babes in this assessment room. Sometimes it just seems such a shame that professional etiquette prevents me from getting better acquainted with some of their best assets, and trying out a theory I've got.'

Jim chuckled 'I bet it's frustrating. I've noticed some of the gorgeous talent in the gym today.' He paused '... so you wouldn't mind getting to know the girls a bit better as well as the guys?'

Jenny gulped and then continued quickly 'That's Lea. She's here almost every day. She was one of the first members I assessed. I think I've said too much now. Let's get on with your assessment, can you hop on the bike?'

Not wishing to embarrass Jenny any further at this stage, Jim did as he was asked and started to peddle.

After 10 minutes of less provocative chat, Jenny asked him to stop and they waited for the print out. As they stood there looking at the machine Jim decided that he'd learned enough about this beautiful girl to push the earlier discussion a bit further.

'You know I've never been one for sticking to professional etiquette' he began 'in fact, I quite enjoy breaking the rules sometimes!'

Jenny looked at him quickly and blushed again. Jim continued knowing now that Jenny wouldn't need much persuasion to follow his lead.

'What's this theory of yours then, and what sort of hidden assets do you think you'd like to see?' Jim asked in a low voice.

Jenny giggled 'You know what I mean!'

'I'm not very bright Jenny. I think you'd better explain' teased Jim.

'Weeelllll' she drawled as she batted her eyelids 'I firmly believe that if someone is sexually excited they perform better in sport, and it would be so good to be able to check.'

She looked at Jim with a coy expression on her face.

He looked back and smiled 'Have you put this theory to the test?'

'Only on myself so far.' She responded.

'... and what did you do?' Jim enquired.

Jenny giggled 'What do you think?'

Jim feigned ignorance again and shrugged his shoulders.

'OK I'll tell you' she laughed 'I knew that I was going to work out in about 20 minutes, so I slipped into the bathroom and checked I was alone, and then I put my hand down my panties and started to finger my pussy.'

Although Jim had known exactly what he was going to hear, the fact that Jenny was now actually putting it into words was so hot. He felt his cock start to harden

'Did you cum?' he murmured.

Jenny smiled sexily 'Of course not. The whole point of the experiment was to get myself as excited as possible without cumming!'

'And you want to try out the experiment with someone else?' asked Jim.

She nodded and looked down at Jim's crotch. 'It doesn't look as if you'd need to much more excitement Jim.'

He laughed 'I guess this assessment has been rather more interesting than I originally thought. Have you any ideas as to how you might conduct the experiment Jen?'

Her face took on a thoughtful look and then she nodded. 'I don't think a man should be prepared for this through physical contact. No, he'd cum too soon and ruin the results.'

'So what do you propose?' Jim enquired.

Jenny batted her eyelids and took a step back. As she did so she took the zipper on her top between thumb and forefinger and gently drew it own. Jim gasped and instinctively put his own hand down to his cock to straighten things out as his excitement increased.

Jenny shook her head vigorously 'No touching Jim!'

He pulled his hand away as she reached the bottom of the zipper and her top fell open. Beneath it was a white sports bra, which held her breasts tight to her chest.

The sexy discussion had aroused Jenny as well, and her nipples pushed hard through the thin material. Jim's cock jerked in anticipation as Jenny put her fingers up to each of her nipples and proceeded to massage first them, and then her breasts. Jim stared in appreciation at the show, wishing that he could just grab his cock and join in with the personal stimulation. Jenny ran her hands up and down her body wriggling before him.

Eventually, after several minutes of teasing Jim, she allowed her hands to touch the mound between her legs. Her mouth fell open as her fingers pressed into the crack of her pussy and traced a line up the fabric of her tight shorts. Then with a swift movement she pushed the shorts down her legs, to reveal a tiny thong. The scrap of material only just covered her pussy, it was clear that this girl shaved her bush. As he stared at her kicking away her outer garments Jim suddenly noticed a damp patch spreading across Jenny's panties. He looked closer as she gyrated before him fingering herself through the increasingly wet thong.

His cock was throbbing with anticipation now, all he wanted to do was let it out and pump his fist up and down his shaft until he came. But he didn't want to spoil Jenny's experiment, and he was enjoying the show too much.

'Tell me if you're close to cumming Jim' Jenny panted, as she continued to rub herself.

He nodded and let out a gasp as she tugged the thong to one side and slid a finger into her exposed pussy. He could now see her glistening cunt lips, parted by her invading fingers. The only problem was that as soon as Jenny heard the gasp she slipped her fingers out of her cunt and pulled her thong back into place.

'Why did you stop?' Jim demanded. Knowing full well that she didn't want to over excite him.

'Believe me Jim' she responded, 'I'd love to finish but I want to make sure you are on the brink when you go out there.'

He grinned, 'Perhaps another look at your pussy wouldn't hurt.'

Jenny shook her head, 'No I heard you gasp and I know what would cum next. Out you go, go on.'

And with a shove she pushed him out the door and bent over to pick up her clothes.

'What about you?' Jim enquired, 'you must be desperate to finish what you started.'

She nodded and grinned, 'Don't worry about me. I've got a plan.'

With that she closed the door behind him and Jim made his way into the gym again. The only problem now, was that Lea was still working-out, and she'd somehow become even more attractive. Jim's cock gave a jerk as he watched her ass sway before him. If only he could get a handful of that beautiful body.

She must have heard him, because Lea glanced up at Jim and grinned as she saw him staring.

'Hey hansom! Like what you see?' she asked right out, as she stood up.

Jim started to redden. He hadn't meant her to notice him quite yet, at least, not while he was staring. But then again, what the hell? Lea had asked him a question.

'Certainly do. I can see how you stay so beautiful.'

This time Lea blushed. 'Thanks, I do my best. I'm Lea by the way'

She bent over and touched her toes, and Jim couldn't resist looking straight down her top. Her tits were gorgeous. He just had to hold them!

Lea looked up again. 'Well I'm off to the showers. Nice to meet you ...'

'Jim...' he responded. 'My name's Jim.'

Lea smiled, 'Jim. Yea, it's very nice to meet you Jim.'

She gave him a wave and turned into the ladies' changing room.

With a big sigh Jim decided he had better get to work on the treadmill. His cock was throbbing away in his pants and he knew what he would rather have been doing. He wondered whether Jenny was just a cock-teaser. After all, this so called research was hardly standard.

As he ran he looked around the gym. He was the only person in at that moment, so it gave him a chance to study the various machines and weights. As he was doing this he heard a door open and saw Jenny emerge. She quickly looked around, and then pushed open the door of the Ladies and disappeared again. Jim groaned. Just imagine the scene in there. Jenny and Lea both possibly naked and showering. His cock jerked again and he continued to run.

After another ten minutes, Jim started to wonder what had happened to the girls. Neither had emerged from the Ladies. He stopped the machine and approached the door. His imagination had started to run wild. Jenny had left him so close to cumming, that now all he wanted to do was to slide his cock into a welcoming hole, he didn't really care which one, or to whom it belonged!

Maybe the girls were showering together. Jenny obviously wanted to try something with Lea, perhaps she'd seized the opportunity! He listened carefully at the door. Hearing nothing, he tentatively pushed it open and peered inside. There was a shower running and he could also hear talking.

'...so you really gave him a show?' came Lea's voice.

'Yea, he loved it. I had to stop him from whipping out his cock.' giggled Jenny.

'Didn't you want to see it Jen?' asked Lea, surprised.

'Of course I did, I could have shagged him there and then, but I didn't want to spoil the plan. I thought if I waited it would all be much more fun.'

'I'm glad you did Jenny, Maggie would have been furious with you if you'd weakened.'

Jim gave a start. Maggie! What did she have to do with all this?

'She should be here in a minute Lea. Quick go and ask Jim if he can help you with something.'

Jim sprang back to the door and quickly tried to look busy. Lea emerged from the ladies with a grin on her face.

'You'll never guess Jim. Jenny's got stuck in a cubicle. She can't get out. Can you come and help?'

He smiled to himself, and put on a look of concern. 'No problem, lets have a look.' he said, and strode towards the ladies again. Lea followed him in and shut the door quickly behind him. Of course Jenny was there waiting. All she had on was her thong. Her breasts were now bared and pointing straight at him, her nipples long and hard. Jim tried to look puzzled.

'I thought you were in need of help.' he said, with a smile playing round his lips.

'Oh, I do need help Jim, I desperately need to complete my research.' She laughed. 'Look at your expression. I hope you don't think I'm ugly or anything?'

Jim grinned, '... and what do you need to do now for your research? Cock tease some more and then watch me in agony because my balls have gone blue with lust? Of course I don't think you're ugly. In fact I would really love to shag you.'

Jenny blushed and her breathing got shallower. Jim could see her breasts rising and falling as she spoke.

'I'll just explain the research first.' Jenny responded. 'Maggie said you'd be an excellent guinea pig. She said you would happily help out. I wanted to find out if after driving a man wild with sexy suggestions and a bit of a show, he would then be able to perform better than normal, if he was made to wait'

'How are you going to test me then?' Jim enquired, increasingly excited at the prospect of fucking Jenny.

'You're going to fuck three of us, one after the other. And we want to see if you can produce as much sperm on the last of us as on the first.' Lea suddenly butted in. She too was naked from the waist up.

Jim gasped. Never in all his fantasies had he imagined three women at one time. He looked around for the third.

'Where's number three then?' he enquired.

Suddenly the door behind him sprang open and Maggie strolled in.

'I'm hear bro. I hope you're ready for us? I'd better get ready.'

Jim watched in awe as Maggie approached Jenny and gave her a hug, then she turned to Lea and kissed her. Lea responded with her right hand, which she placed over Maggie's breast and started to massage. Maggie gasped and quickly stood back to remove her top. The others looked on as her breasts came into view. Then she hastily pushed her jeans down her legs, leaving only her panties.

Lea followed suit and removed her track pants. Now Jim had three delicious girls parading, virtually naked, before him. 'I think it's about time you got your kit off bro.' laughed Maggie as she watched the expression on his face.

Jim didn't need asking twice. In seconds he had his vest off, and then with a final tug he released his cock from the constraints of his shorts. He couldn't remember growing so big before. Even when playing around with Maggie. The girls looked on admiringly. Lea put her fingers down to her mound and gently rubbed her clit through the soft cotton of her panties. Maggie slipped her hand inside her thong and slipped a finger right into her pussy. Jenny meanwhile watched the girls for a second and then brushed her hand over Lea's left breast. Lea let out a sigh and closed her eyes, as Jenny massaged and tweaked her friend's nipples.

'I've never done this before!' gasped Lea as Jenny leaned forward and took a nipple in her mouth.

'Don't worry, you'll enjoy it!' murmured Jenny, between sucks. 'We girls know how to pleasure each other better than any man can.' And she moved her hand down to cover Lea's as she rubbed her pussy.

Jim looked on in awe. This was every man's dream come true. Three women here to pleasure him and playing with each other as well. He stepped towards the girls and slipped his arms around his sister's waist. His cock pushed into the crack of her ass. Maggie wriggled, and her tits swung in a most tantalising way. Jim brought his hands up and caressed them, feeling the nipples harden beneath his touch. Brother and sister watched as Lea and Jenny made out before them.

Jenny tugged at the tie on her friend's panties and the skimpy piece of cloth fell away to reveal a completely smooth pussy. Lea gasped and fell back against the wall as Jenny proceeded to part her pussy lips with her fingers. Lea's cunt was obviously excited, as her labia were engorged and pink, and as her friend penetrated her crack she let out a squeal.

'Oh Jenny, yesss, fuck me with your fingers!' Jenny started to move her fingers up and down Lea's cunt and as Lea got more and more excited she positioned them over her friend's hole.

'Can you take three fingers darling?' she panted. Lea nodded vigorously and with a swift movement Jenny slipped most of her hand into her friend's cunt. Lea let out a loud gasp and started to pump her hips against Jenny's soaked hand.

Meanwhile, Jim had pushed his cock right into Maggie's ass crack. She lent forward, not taking her eyes off the show in front of them. He moved his hands round to the ties on her thong and pulled sharply. His sister's panties came away in his hand to reveal her trimmed red bush. Jenny looked over and watched as Jim positioned his cock at the base his sister's pussy and started to rub it up and down her crack. Her lips parted to receive his meat, and then she lent further forward and her cunt suddenly engulfed Jim's throbbing cock. Jenny let out a groan as she watched her friend being fucked, doggy style by her brother. This was too hot!!!

Lea hadn't missed the action either. While Jenny pumped her pussy, Lea watched open mouthed as Maggie swung her heavy breasts in front of her. The nipples were swollen and bright pink, just begging to be sucked. The combination of the scene before her, and Jenny fucking her with her hand brought Lea to a rapid climax. She let out a howl and clamped her thighs together, crushing Jenny's hand as she did so. Her pussy contracted rapidly round her friend's fingers, and then with a slurping, squelching noise she ejaculated a stream of girl cum over Jenny's arm and the floor.

Maggie gasped as she watched the blonde pour her cream down Jenny's arm. She thrust back, to feel Jim's balls slap against her butt, and his cock slipped right up to the hilt in her excited cunt. She reached down and slid her fingers rapidly over her clit. The nub of swollen flesh throbbed with pleasure, sending waves of ecstasy right up her crack. Then she excitedly thrust her finger into her pussy alongside her brother's pumping cock, and hooked it up to touch her G-spot. The effect was immediate. With a shudder, which ran from her toes up to the top of her head, and back down her arms to her fingers, Maggie came in a gush of cum. Jim felt the hot liquid pouring over his balls and dribbling down his legs as he continued to fuck his sister. He could feel his own climax approaching, but he didn't want to cum yet, so he withdrew his cock quickly and took a step back from his sister. Maggie let out a groan.

'I want you to fill my cunt, you bastard! I need your cum!'

Hearing his sister talking this way excited Jim more than he could imagine. His cock twitched and he felt he had to release some of the pressure from his balls. He looked down and watched, fascinated, as instead of ejaculating, his cock suddenly twitched again and then a stream of thick, creamy cum oozed from his hole and dribbled down his shaft. It felt incredible. It was like taking a pee, but with sperm instead of pee. Jenny noticed this and looked on admiringly.
