There are few things that would keep Ali up in the middle of the night, but a message from her friend Shaun earlier in the week had brought her to this point. It was the night before going to her new local gym for the first time.

It was 2am before a 7am appointment with a new PT and she couldn't wait. Shaun recommended it to her when he found out she was moving house.

At 6:50am, she pulled into the almost empty parking lot, scanned her ID, and went in. The new PT was getting gear ready and introduced himself when he saw Ali walk in. This guy was clearly happy to have her as his first client of the day and she knew it.

After a thorough assessment and a walk through of the flashest gym she had ever seen, he pointed Ali to the women's lockers.

The locker rooms at this gym were flash. Mirrors everywhere with "love who you are" and other motivational messages above them, bright LED strips around the edges, just begging to have selfies taken in front of.

Whether it was the extra effort she put in to impress the PT during deadlifts, the new Alphalete leggings (navy blue, especially for the new gym), or just the lighting, her ass looked outstanding.

Instagram was out in a flash. Ali turned to find her best angle (not that it took a lot of effort, there were a lot), drew and *click* went the shutter.

She posted it with nothing but a peach emoji as the caption. Before she could even put her phone in her gym bag, it dinged with a comment from Shaun. She smiled at the speed of his reply, but would read it after a well-deserved shower.

Dropping her phone, Ali pulled her sports bra off her tiny frame, the elastic at the bottom brushing her nipples on the way past, wrapped her towel around her chest, and peeled off her leggings and bright red thong, loosely throwing them over her phone.

Shower time.

The water pressure was intense. But it was just what she needed to wash off the morning sweat. Ali thought about the message from Shaun and how quick he had replied. Something about the hot water over her body, the privacy of the shower cubicle, and one of the thousand things he could've commented in that short time had culminated in her back resting against the cubicle wall, water shooting out onto her small perky breasts, and her hand running down her own body in an eyes-closed daze.

Her own fingertip inches from her always tidy landing strip brought her back to reality. With a shake of her head and a quick reorientation of where she was, she turned the shower off and walked a little slower back to her locker, past the mirror she had taken the picture at earlier. If she had more time, she might've gone back for a colder shower.

She dropped her towel off her body, put on fresh underwear and her favourite jeans which also showed off her sensational ass and legs, but clung to her tiny waist.

Ali opened the comment from Shaun. "Good enough to eat" with a tongue emoji at the end. She thought for a moment and tapped  out a non-committal but fun reply in a DM. The world didn't need to see this.

"Promises, promises."

Seconds later, it dinged again. "Just how long a shower are you having? Get out here."

Her heart pounded. Where the hell was he?

"Where are you?"

"Outside. Sounds like I have a promise to keep."

Still stood in the locker room. jeans and shoes on, bra hanging in her empty hand, she felt her pussy pulse at the idea of him right outside.

Ali threw on her dark grey tank top and discarded her bra into her bag, feeling like she wouldn't be needing it. She all but ran out the gym door, looking around for Shaun amongst cars (there were a lot more since she'd gotten there earlier).

"Over here," he called from the side of the gym. As Ali turned to the call, he was already getting up off a small bench and heading towards the corner of the building, just out of sight. She headed his way and when she reached the corner she'd seen him slip behind, he pulled her out of sight, pushing her back against the brick wall in a playful but firm way, standing over her in his 6ft frame.

"So how do you like my gym?"

Ali decided that small talk was only going to make her late for work. "It's good, but I probably should've stretched more after..." she said, turning herself around to face the wall, arms stretched high above her head, pressing her ass backwards straight at Shaun, starting a gentle rocking motion.

Without even replying, his hands were on Ali's tiny waist, dragging his palms up the sides of her ribcage, taking her tank top with it up her toned body... a mix of gentle fingertips and firm grips from his hands while she innocently continued her stretching, her heart racing at Shaun's touch, anticipating his next move.

Her tank top bundled up around the top of her chest, exposing her breasts to the cool morning air had made her nipples hard, and one of Shaun's hands was easily going to work on teasing across both of them, the other tracing his fingernails down Ali's spine, her back arching in response when he reached her waist, hooking his arm around the front and immediately getting to work on unbuttoning her jeans, hungrily prying them open to sink his hand inside her underwear.

Shaun wasted no time dipping his fingertip inside her, feeling her warm wet pussy, dragging his digit almost to her clit, teasing it by sliding back to where it started. Each movement of his forearm nudging her jeans down more, the gentle swaying of Ali's ass slowly exposing the top of her thong at the back.

A car door slamming nearby in time with a tight grip on her nipples sent a jolt of excitement through Ali's body, coating Shaun's fingers in her sex, rocking her hips in time with his fingers pumping in and out of her, forcing soft moans from her barely open mouth between bites on her own lip.

Shaun leaned in to Ali's ear, pressing his body against her, growling, "Lose them."

She knew what he wanted. She let one hand go off the wall, using it to inch her jeans over her breathtaking ass, down her thighs, the tight denim keeping her legs together, but her perfectly formed thigh gap giving him unhindered freedom to enjoy the space left by her jeans, thrusting his fingers inside her soaking wet pussy a couple more times.

Ali felt Shaun's arm leave her chest, her body now exposed from above her small perky tits to halfway down her thighs. He wasted no time kneeling down behind her, kissing her bare back left and right as he sunk down, both hands gripping her delicious ass, biting his way down it. Shaun hooked his hands around the front of her hips, pulling Ali's juicy pussy back, and after some playful kisses on the back of her thighs, Ali felt him fulfill his promise from the earlier Instagram DM. His tongue was pressed flat against her soft wet lips, expertly dancing around on her smooth fuckhole, her ass instinctively pushing back against his face.

With her free hand, she worked her clit, pressing hard with her flat fingers, circling around in time with Shaun's tongue that was devouring her from behind. If anyone took a wrong turn out of the gym doors, they were in for a real treat. The excitement rushed through her in the form of a loud moan, and Shaun took his cue.

Removing his mouth from between her thighs and ass, he stood up slowly behind her, circling his hand over her toned ass before giving it an open-palmed smack, leaving a red sting. With his arms back in position around her chest, gripping onto her tits, nipples clamped between his fingers, he rocked forward sliding himself between her thighs, nudging her hand. Caught up in the moment, Ali hadn't even noticed Shaun drop his shorts and underwear, her only clue the rock-hard throbbing cock now dragging back and forth under her, glistening from her own wetness.

Ali retired from her clit, hooking her hand underneath Shaun's ample cock, feeling it pulse in her hand when she pulled it upwards, forcing it to slide harder against her.

Enough teasing. Shaun pulled back just far enough for the head of his cock to line up with Ali's welcoming hole, her pussy happily swallowing him up, making them both groan in delight. Once inside her, he ran his hand up her back, bundling her long dark hair in his fist, tugging back, speeding up his thrusts and all but forcing Ali to impale herself on him. She had been aching to be fucked like this for so long... just taken and stuffed full. With both her hands pressing off the wall in front of her, Shaun timed his thrusts with her to ensure he drilled in as far as he could.

Ali's wrist buzzed... time wasn't on her side. "God yes just fuck me hard," she said probably too loud.

Shaun didn't need more encouragement than that. He sped up, pumping into her lovely pussy deeper and harder, her body jolting from each impact, feeling him swell inside her. As much as she wanted him to cum inside her hungry pussy, she decided the lack of protection was probably careless enough. As Shaun pulled back to again shove his cock inside her, Ali pushed him back gently, turning around and dropping almost to her knees in a controlled squat.

One hand sunk between her thighs, giving her clit exactly what it needed. Electricity shot through her and when she looked up at Shaun, he stepped forward so her hand could guide his cock into her beautiful mouth.

"Holy fuck that's good, Ali," he groaned rocking his hips forward and back, watching her take almost the whole length of his cock in her mouth. Tongue lapping up the sweet mix of her own juices and his precum, her hand went from support to active duty, pumping his cock and jerking him into her mouth.

His pulsing cock let her know to be ready, pulling her head back, moaning at the sensation of her own fingers inside her, dragging up her sweet wetness to her clit, her legs shaking from balancing carefully on her feet.

"Fucking cum for me. I want it." Ali eagerly licked her lips and felt Shaun's cock swell in her hand. With a sharp thrust and a guttural grunt from his mouth, the first shot of Shaun's hot cum landed on her tongue, extended out of her mouth like a runway. She turned her head for the next to hit her cheek, then wiped it across to her other, watching him writhe in ecstasy. His unloading in and on her, showcasing herself to him as a hungry cumslut, the chance of being caught in broad daylight with her jeans halfway down her thighs and cum dripping off her chin to her bare chest sent her over the edge.

Ali clamped her thighs tight around her hand, wrapping her lips around Shaun's cock to muffle her own moans as her orgasm rippled through her with the intensity of three simultaneous natural disasters.

Both panting, exhausted and satisfied, Shaun encouraged Ali up with his hand under her chin, enjoying the view of her coated in his cum. She looked around for anybody who might've seen or heard while she pulled her thong back up, followed by her jeans to press the cotton of her underwear against her freshly fucked pussy.

Shaun handed her his towel, which she quickly used to clean herself back to almost pristine condition.

"Told you I could keep a promise," said Shaun with a smirk, hoisting his own underwear and shorts back up around his waist, an obvious erection still in plain sight.

"Asshole," Ali replied with a smile, taking her phone out and picking up her gym bag. She dialed a number before walking away and said, "Hi yeah I'm on my way, I had a last-minute breakfast with a friend. I'll be right in," walking backwards to see Shaun head back to his own car.

Ali guessed he had gotten all the exercise he needed for one day.
