Pamela climbed the stairs from the dressing room to the main gym with anticipation: she always enjoyed her late-evening exercise, it was her relaxation and meditation time. This had been an awfully tense day at work, so tonight there would be no weight-machines, just a long ride on the semi-recumbent Exercycle, then a thorough stretch.
She scanned the room: her favorite machine was free, the front one nearest the treadmills. Treadmills she didn't use: they made her knees sore. She adjusted the seat, then settled onto the saddle and keyed in her program, got her earphones on and radio tuned to the good jazz station.
The reason for her choice of machine was simple: the long row of treadmills in front of her almost always had at least one or two (often several) attractive men jogging away, her own discreet body-shop. Not to mention the men stretching on the mats just off to her left. A girl could have a good time this way, at least optically: she always did.
Of course, it hadn't ever led to anything. In her many months of membership, the one time she'd been approached (by a very cute, muscular blond guy ten years her junior: flattering!) it hadn't taken ten seconds before she was sure there was only hard vacuum or dense fog between his ears. It would be nice, she thought, if she could get her now-slug of a husband to join. On the other hand, if he did, it would certainly inhibit her fun as observer. Oh well.
She started pedaling, settled into her rhythm, and observed the surroundings. Most of the people were regulars. But on the treadmill most directly in her line of sight was someone new, in a bright green running singlet -- and with a GREEN towel over the control panel. Cute, she thought: NOBODY used a colored towel! He was running fast, loose, good style, the man looked just fine. She eyed him: new meat! Good legs, compact muscular build. He had already been running for some time: his arms and legs glistened with sweat, the front of his singlet stuck to his skin, showing useless little nipples.
She wondered if he were new to the club, or just new to this time of day? Mr Green had a full-membership club ID clipped to his waistband, so he certainly wasn't just a visitor or some member's guest. And even from her distance she could tell the card wasn't pristine: not a NEW member, either. So where had he been? Maybe a change of shift or habits had moved him from another time of day. Idle speculation, but she hoped that he'd be a regular at her time. Scenic improvements were always welcome.
Pamela glanced away as his eyes shifted her direction. She positively felt them settle on her, then sweep past. She looked again: his eyes were discretely scanning the room, studying. She followed his gaze as best she could, found it fixed briefly on the crotch of one of the women doing stretches. She smiled to herself: perhaps Mr Green and she were players in the same game? She watched him watching other women. He was nicely inconspicuous about it, nothing obvious or obnoxious, never stayed focused for too long on any one person, didn't move his head much, but it was clear once you studied him.
He fixated for a moment on a youngish, big-busted woman in a tight leotard. Pam took the opportunity to study him more closely. Very nice legs indeed. Full beard, neatly trimmed, good arms and chest, the musculature not overly defined but strong. She wondered why he was running in a Speedo racing swimsuit instead of runner's shorts? Maybe he was showing off? Perhaps he'd learned to run at the beach? Maybe, just to be simple, he found it comfortable? She could understand any of the options, was happy he'd chosen that revealing costume: he did have quite a nice bulge, and through the damp thin material she thought she could make out the bump that would be the edge of his cockhead. That, she thought, meant circumcision, a naked plum.
Her belly twisted slightly: she'd always felt that her view of cock-traces was probably a lot like a man's view of nipples. Exciting due to what remained concealed. The hint as teaser.
His age? Indeterminate. Certainly between 40 and 55, a good mature forty or a very well preserved (plus good genes!) fifty five. Nice to live in an era when one couldn't tell any closer than that. She wondered how he would evaluate her own looks? His gaze rotated towards her, she went back to staring at the control panel, but she could feel his eyes on her now. Much to her surprise, she found the very thought made her nipples spring to attention beneath her top: she wondered if he could see the bumps through her exercise bra, and found herself wondering why in the world she hoped that he could!?
Pedal pedal pedal!!!
He studied her for quite some time. That was interesting, flattering - after all, he did have quite a range to choose from out there. Every now and again, they would make very brief eye-contact: that embarrassed her. It wasn't often she got caught. But he didn't seem to mind, just smiled at her when it happened, always broke the contact himself (very gentlemanly of him!) and went back to scanning the room.
Then a little commotion on the mats, two eighteen year old girls settled down to their giggle-fest and minor stretching. His eyes shifted to watch, his pace never varied, his head didn't advertise his gaze. Considerable baby-fat, lots of tit, long legs, both blond, probably very appealing to Mister Green, she thought. Phooey!.
She glanced down at herself, wondering what it was he'd found so fascinating, tried to estimate what he could see given his line of sight.
OOPS! Her face reddened brightly as she realized what was going on: her running shorts were riding up, the pedals and her pose were such that her legs were slightly spread. With every pedal rotation he must have had a clear view of her crotch, covered only by the nearly-transparent inner liner! And most likely, the bottom of her butt was hanging out quite blatantly.
