Carrie and Mike walked through the open bay garage door and onto the heavy rubber mats of the gym. Others were already loading plates onto bars, while a coach led a small group in the corner through basic movements. Carrie was a regular, and quickly staked claim to one of the many squat racks and platforms, adorned with every accessory you could imagine: pullup bars escalating from the top, a target for medicine ball throws, and stacks of bumper plates next to several different types of barbells.
Mike finally caved to Carrie's insistence that he tag along one day, changing up his routine from a different functional fitness program at his gym for hers. He was instantly impressed at the quality of the facility, noting the long turf inside, with several sleds and apparatus for dragging, carrying, and pushing. Mike also took note of the other athletes, slightly more women than men, and all wearing less than would be accepted at his gym. Overall, this was an impressively fit and serious-looking group, which didn't surprise Mike at all: Carrie fit right in. She has been training for years and always ate extremely healthy; she's earned thick, powerful legs, broad, muscular shoulders, an impressive set of abs, and yet retained her femininity with a few softer curves and a beautiful, somewhat fierce face and piercing eyes. Likewise, Mike's efforts and naturally lean frame resulted in an equally fit and impressive physique, very often noticed by women (and some men) when he was out.
It's been several weeks since Carrie overheard Mike watching porn in his room, and let herself in. What happened next was a fantasy come true for Mike, and exhilarating for Carrie, who only then realized her attraction to Mike. She was worried she had crossed an unwritten, unspoken line when she asked to watch Mike masturbate, however seeing the most beautiful erection she'd ever seen focused her attention only on physical gratification. She intended to stop their game of "show and tell" after they both climaxed, however watching how dirty Mike could be, having back-to-back orgasms all over himself, drove her wild until she couldn't resist, pushing her over the edge of rational decisions to sinking herself onto him. What happened next began as purely physical lust; the mess Mike wore on his face after his first and second orgasm was too alluring to ignore her needs. But that messy kiss, the first she's had sharing a man's cum with him, quickly turned into one of passion, not just lust. She rode him until they collapsed back, her begging him to finish deep inside her so she could feel that gorgeous, thick, and long cock pulse and throb as he filled her, setting her off one last time in a loud, clenched moan.
As Mike came down from his orgasmic high, he too was worried about the change of dynamic in their otherwise platonic relationship. Showering and trying to keep to himself, really to give her space, he wandered to the kitchen. She was already there as he walked in, pulling a bottle of wine from the cabinet, a large glass already in hand. Sheepishly, all he could muster was "hey," with his typical Mike smile, unsure of what else to say.
"Hey yourself" Carrie replied, their standardized greeting.
Both stood still for a moment, faces reddening, both unsure of their next move, or even if there was a move to make.
Without warning, and almost without her control, Carrie blurted out "That was fucking amazing!" with a giant smile, then seemed to catch herself with a hand over her mouth.
Mike's instant broad grin confirmed that she hadn't made a mistake. He beamed "It was... it was fucking hot. You... you were incredible... I didn't know you would be into any of that... and you're beautiful..."
"You're not so bad yourself there, mister. And your dick! Had I known what you were packing, I wouldn't have waited so long to ride you!" She joked, all the tension and ice in the room vanishing.
Carrie offered Mike a glass and to share the Cabernet in hand, as they wandered to the couch as two roommates and friends, who just discovered an erotic, lustful, and even romantic spark between them, both aware of its magnetism and playful tension.
Both fell into the routine of playful flirting, even it was a lot of shit-talking, waiting for the other to finally act.
Back at the gym, Carrie set up the rack and loaded her bar with a decent warmup weight. Mike stepped over to the turf and started to go through his routine, swinging his legs high as he walked before pulling his ankle to his glutes for a stretch. He couldn't help noticing the women clad only in short gym shorts and sports bras; his glances weren't so much sexual as they were admiration for these trained athletes. The men, too, mostly shirtless, exuded strength and power, accented by each cut and visible muscle across their bodies. Mike admitted to himself that while he wasn't quite as bulked out as they are, his definition and strength was still impressive, if not much leaner. Finishing his warmup, Mike trotted to Carrie's platform in time to catch her tossing off her shirt. She was gorgeous. The straps from her sports bra seemed to accentuate her traps and delts; she wasn't bulky, but her physique was powerful and sexy. Her messy ponytail fell into place, pulled tight enough to reveal her high cut, the shaved sides of her head adding an element of boldness and edginess only when revealed.
"Are you fucking joining me or what, Mike" Carrie snapped as he approached, smiling.
"Yeah, yeah... I just had to admire you from behind is all," he replied, adding another line to the growing spark of tension between them.
"Surrrreeee you were..." then, lowering her voice, "Just don't let that big fucking dick of yours get hard in here, alright?" She teased, demurely, knowing the effect it would have on him.
"I'm not sure about that, it might be kind of fun," Mike said as his eyes obviously fell to her chest, her cleavage revealed by her low-cut sports bra. He instantly recognized it as the same bra she stripped off the first time he saw her, which helped immediately push him over the edge as she came, now topless. He might be in trouble as he felt himself swell behind his boxer briefs and his gym shorts.
Carrie started her first working set with practiced, disciplined form. Mike did everything he could to ignore the shape of her ass through her shorts as she went "ass to grass" in squat depth, and the sight of her smooth, powerful legs. She racked the bar as Mike stepped up; Carrie's height was almost his own, simplifying repping in, and making Carrie seem even more powerful than she already was.
