Running. There were some consequences of a brisk jog that Sienna always could rely on. Firstly, it always made her sweat, of course, and she secretly enjoyed the way the salty, sticky perspiration pasted her running top and leggings to her skin. Second, there was always that heady, invigorating rush in her brain from endorphins released through physical exertion, giving her a charge throughout her entire body. Thirdly, it always made her feel strong, not like an ox per se, but more like feeling emboldened by a sense of accomplishment that left her wanting and ready to take on more, more, more.

Then, there were other side effects that tended to occur from time-to-time. Tonight, for instance, it made her feel horny. 

Very, very horny. 

Perhaps it was all the aforementioned effects combining together in a perfect mix of libidinous brain candy that she just needed to suck on, but she was feeling a little antsy and randy even before her run.

Restlessness had pulled her from her bed at 3:45 a.m. in the form of a prickling tingle that crawled under her skin. She didn’t fight it. By 4:00 a.m. she had already exchanged her nightshirt and panties for a tank top and stretch shorts that hugged her skin like plastic wrap, and was outside pounding the pavement in her beaten running shoes at a quick pace. It was a humid night and it didn’t take long for her skin to become all shiny with trails of sweat streaking down her face, neck and back.

The heat, the activity and the solitude of the night played tricks on her mind, freeing it to wander to those neural regions where naughtier thoughts and cravings were so pervasive. For approximately the last fifteen minutes of her five-mile run, she indulged in these tempting daydreams which served to spike her heart rate and quicken her pace. She was rewarded with a surge of those sweet, sweet endorphins, pushing her through the mental wall and feeding those burgeoning desires.

Her route was not unplanned, despite the impromptu decision to go for a run.  After jogging through the neighbourhood, she made her way onto the main street, running briskly by the darkened, closed shops and offices that lined the avenue. At the end of the road was the only open business, a 24-hour convenience shop. From a hundred meters away, she had set her sights on the dull-grey glow of the lights from within and charged hard towards it like a moth to the flame.

It wasn’t a thirst for refreshments alone that compelled her.

She pulled up just outside the doors, huffing and puffing, hunched over, hands on her knees. Little splashes blotted the pavement beneath her as sweat rolled down her face and dribbled off her chin and nose. She smiled, pleased with herself. 

Good run. Time for a little reward.

Standing upright, Sienna inhaled deeply and exhaled a steady stream of hot breath from her pursed lips. She swept her fingers through her damp hair, readjusted her ponytail and shook out her arms and legs before opening the door and striding inside, confident and tall.  

It was only slightly less heated in the store, the noisy, exhausted A/C churning out air that was more musty and mild rather than a cool, fresh blast. As she walked along the front of the store toward the middle of three aisles leading to the back, her cat-like eyes strayed towards the service counter, only a glance, but long enough to recognize and connect with the young man standing behind it.  

“Hello, ‘John’,” she said with a coy smile as she turned sharply and walked down the aisle away from him.

“Hello, Ms.Sienna,” he replied.

‘Ms. Sienna’. She grinned and giggled to herself. It reminded her of the way her Grade 4 students referred to her at school. So polite, yet, she was pretty sure she felt his eyes affixed on her spandex-covered ass as she walked with a deliberate wiggle of her hips to the back. That wasn’t so polite, but she kind of liked it… a lot.

Truthfully, she knew his name really wasn’t ‘John’. The owner of the store was a cheapskate who invested in only one grimy name badge which was passed along to the rotating door of young men --often foreign-exchange college students-- who did the overnight shift (ie. the ‘shit shift’).  ‘John’ was about as generic a name the owner could come up with so that any poor schmoe could wear it. The fellow currently behind the counter was at least the fifth ‘John’ that Sienna had introduced herself to over the past year, though, with that Latino accent of his, she suspected he was more likely to be a ‘Juan’ rather than a ‘John’.

Whatever his name, with his good looks --olive skin; a tall, lanky frame; dark green eyes; long wavy hair-- and amiable, borderline flirtatious attitude, she was certainly appreciative that this current iteration of ‘John’ had decided to stick around longer than most of the others.

Sienna took her time strolling down the aisle, running her finger along the shelves cluttered with packages of processed “food”. She wasn’t seriously considering any of it, but she knew her lingering allowed John ample time to ogle her butt and legs.  

“Hot night out there,” she called out again.

“Yes,” he said, “reminds me of home.”

“Home? Oh, yes, Argentina,” she noted, recalling a previous brief conversation she had with him. “Home of the Tango.”

“I’m actually from the city where the dance originated: Buenos Ares,” he replied.

“Is that so?” Sienna said, a curl on the edge of her lips. She enjoyed how he leaned hard into his accent inflecting a slight growl as he rolled that ‘r’ sound with his throat and tongue. 

She approached the refrigerated area, opened the door and inhaled deeply, sucking in that familiar coolant smell, artificial yet somehow oddly invigorating. Though it was completely unnecessary, she leaned forward to peruse the drink offerings on the lower rack, propping her butt back, still certain of the pair of eyes trained on it. Cold air wafted across her face, neck and shoulders, cooling the sweat on her skin and clothing.

She selected a generic bottle of water and then an ice cream bar from the next door freezer. As she pivoted around, she noticed John immediately raise a book in front of his face.  

“What’cha reading?” she asked as she made her way back to front, though she knew that for the last couple of minutes his attention hadn’t been on the words on the pages.  At least the book wasn’t upside down, she thought, giggling to herself.

John showed her the cover of the book, an Economics text.  

“Taking Business in school?” she asked.

He nodded.

“Good for you,” she said, smiling with her tongue firmly pressed against her cheek. She arched a brow and glanced around the store. “Guess we all have to start from the first floor.”

He shrugged and grinned. “More like the cellar.”

She winked at him and said, “I meant that as a compliment. Good to get your hands dirty. It’ll make you appreciate your successes even more.”

She couldn’t help letting her teacher instincts out sometimes.

Sienna placed the ice cream on the counter, still holding the bottle of water.

John asked, “Will that be all?”

“Haven’t decided, yet,” she said. “How much for the water?”

“Sixty-nine cents.”

She grinned, chewing her lower lip as she did. She stepped back to give him a good view of her down to her shoes. Clamping the cold bottle between her thighs against her crotch --not a completely uncalculated act-- she patted her butt, thighs and chest with her hands then held them aside and shrugged. Obviously, she hadn’t brought any money with her; her skin-tight clothing would have made clear the outline of any coins or cash on her person.

“Care to barter?” she asked.

John paused, staring at her with a coy smirk.  

Sienna had been in line before when John was at the counter and some kids in front of her were looking to buy some chips. They didn’t have enough cash, so he suggested “bartering”.  When they asked what he meant, John folded his arms and said, “Entertain me. Show me a trick in trade for the chips.”

The kids quickly clued in and did a couple of handstands, floor spins and leg kicks. It was silly but seemed to amuse the store clerk enough and Sienna, as well. When they started to yap like monkeys, John sent them on their way with their booty in hand.   

Sienna witnessed him barter a couple of more times with kids. It was clear he really didn’t care that the store was missing out on some paltry sales.

“So?” Sienna prompted. John seemed to be stuck pondering if she was serious or not.

“You’re not a kid,” he said.

“No. No, I’m not,” she replied, hands behind her back, swivelling her hips side-to-side. “Thank you for noticing.”

He folded his arms as he continued to eye her. It offered Sienna a good look at the mesmerizing tattoo sleeve covering his left forearm. 

Finally, John nodded. “Drink it.”

She tilted her chin aside and peered at him from the edge of her narrowed eyes. She felt a twinge of disappointment. Part of her thought it a somewhat unimaginative suggestion, the other part realized John probably didn’t expect much for sixty-nine cents. He was a business student, after all. 

“What? You mean here?” she asked. “Now?”

“Yes.” He nodded again at the bottle. “Here... in front of me. Drink.”

Sienna frowned, then blinked. The way his eyes fixed upon her and how his lips had drawn into a sharp, slanted line was enough to convince her that he knew what he was asking for.

“Okay,” she said.

The cold plastic bottle was sweating with condensation that had built upon it from the warm air. Sienna pressed it against her cheek, closing her eyes and smiling.  “Mmm. Nice,” she hummed.

Unscrewing the top, she raised it to her lips and took a little sip. The cool liquid slipped refreshingly over her tongue and down her throat. Then, she tilted her head back and raised the bottle. With languid gulps, she drank, her eyes open and watching the clear water ripple and sway inside the bottle as the level sank. The store was silent save for the soft satisfying sounds of her swallowing. She hummed again and rivulets of water seeped from the edge of her lips down her chin and neck, and under the neckline of her halter top.

With the water almost gone, Sienna decided at the last moment to spice things up. Darting her pink tongue thru the top, she lapped the remaining drops then sucked hard, her cheeks going sallow. After one last resilient gulp, she crushed the bottle in her hand and gasped as she pulled it from her lips.

Spiking her brow, she turned her head to regard John. She could tell by the mesmerized look on his face that he was contemplating popping open his till to give her back some change.

“Fair trade?” she asked with a coy grin.

John mirrored her grin and nodded.

Sienna eyed the counter. “So what about the ice cream?” 

He looked at the frozen treat, skewing his lips aside. “That’s kind of a premium item. Probably shouldn’t just give it away,” he sighed with his shoulders slumping. He seemed apologetic, inferring that small bags of chips and bottles of water were the limit to his bartering allowances.

“Hmm,” Sienna replied, pouting. 

“Maybe a freezie?” John suggested. “Those are like fifty cents.”

She rolled her eyes up and to the right as she thought about it. While she could probably have just as much fun consuming a freezie as she did the water, she really, really wanted that ice cream… among other things in the store.

A devilish look darkened her eyes as she regarded John standing patiently behind the counter.  Fixing him with a provocative gaze, she reached deliberately towards the counter. “No… no, I think I’d prefer the rich chocolatey and creamy taste of this ice cream,” she said as she picked up the confection, “and I’m more than willing to pay for it in trade.”  

John smirked and chuckled, shaking his head.

Sienna slowly stepped back pointing upwards with her eyes towards the camera on the wall behind the counter. “Now, I know for a fact that the owner of this place is too cheap to actually have a working surveillance camera, so it’s all on you… John.”

He watched in bemused silence as she made her way with unnecessary stealth towards the exit. 

She stopped by the door and said, “To make it absolutely clear, you can try to stop me as I walk out and make my escape to the right and around the back through the alley. Use whatever means necessary and all that.”

That cracked his lips apart with a sharp, toothy grin. 

As she opened the door, she flipped the “Back in Fifteen Minutes” sign around. She threw him a luring wink and added, “Just make sure you lock the door when you do. You never know what type of desperate people are roaming the streets at this time of night.”

Sienna exited. Though the air conditioning in the store had been negligible, the heat and humidity still hit her, a pasty film almost immediately adhering to her skin. She strolled along her ‘escape’ route: to the right, around the back to the alley behind the store. The area was enclosed with a fence, the way she came in being the only way out. 

Trapped. Oh… well.

She leaned up against the rear staff exit of the store, beneath a single overhead lamp that cast her under a cone of bright yellow light. Tearing apart the wrapper, she removed the ice cream and wrapped her lips around the tip, sucking on it till a chunk broke off. Rich dark chocolate and velvety vanilla cream melted deliciously in her mouth, as she smeared it against her palette with her tongue before allowing it to seep down her throat. All the while, she kept her eyes on the front of the alley. 

Moments later, a dark silhouette --a tall, lanky frame-- appeared.  She heard the sound of a lighter strike and watched as a small flame was raised to light a cigarette, the face of the store clerk lit up momentarily before it was extinguished.

Sienna took another suck of her ice cream, licking her lips of every sticky coat of sweetness she found there.  “You know, those aren’t very good for you,” she remarked regarding the cigarette.

As he stepped closer into her light, John nodded. “That’s probably true.”

“Should trade it for another activity,” she suggested.

He stood before her casually, hands in his pockets. Sienna noted he had unbuttoned his store shirt, revealing a white tank top beneath, his swarthy skin glistening with perspiration above the neckline. It was a good look.

“Like what?” he asked, taking a hard drag from his cigarette, then flicking it aside. He took another step forward, moving into her space, blowing the smoke from the side of his lips.

“Something healthier,” Sienna said, her eyes raised as her back pressed against the steel door. Almost involuntarily, she felt the muscles in her thighs and buttocks flex as took in the young, handsome figure standing before her.

John drew a slow, deep breath and leaned in and over her, pressing his hand against the door just above and to their right of her head. “Like eating ice cream?”

“It’s a hot night and I earned this,” Sienna said, knowing full well she hadn’t actually paid for the confection, yet. She was growing anxious, revealed by a barely perceptible shake in her knees and a restless shift in her hips. Eyes locked on his, she attempted another sampling of her ice cream only for John to clutch her by the wrist and raise it to his mouth. He clamped his lips around it, taking a large chunk of it as she pulled the stick slowly from his lips.

She watched his lips churn as he ate the ice cream, still maintaining that assured smile of his. She admired how quickly he had embraced this cocky attitude -- so bold, so certain of himself.

After sucking the stick clean, she gave her thumb a little lick, sweeping away the last of the ice cream that had dripped on it. Then she said, “I was thinking something more physical.”

John placed a hand on her shoulder and thumbed her halter’s shoulder strap. “You mean like running?”

Sienna shook her head and reached forward, sliding her hands up his belly and chest and around his neck. “You know there’s other ways of working up a good sweat… and I don’t mean the Tango.”

Abruptly, she pulled his face down and towards her, slamming her mouth against his. John seemed more than prepared, quickly smothering his long frame against her, pressing Sienna’s back against the door. Their bodies immediately exchanged heat and sweat as they engaged in a smouldering kiss, trading the flavour of smoke and ice cream between their gaping mouths and lashing tongues.

Urgency set in quickly. She realized she was shaking, her hands fluttering all around his body and face as if she didn’t know where to begin. The run and the teasing in the store had really got her worked up, and the rampant urges she had built up were now in full release.  

At some point, John had clutched her by the wrist and pinned her arm above her head, his free hand massaging her breasts roughly through her halter top.  

“Suck on my tits,” she gasped.  

The next moment, the tall Latino was leaning down, shoving the bottom of her halter up to her neck, freeing her glistening breasts and exposing them to his indulgent licks and suckling. Her nipples hardened, so taut and tight that they ached.  

While his tongue and mouth worked on her chest, his hand busied itself stroking her crotch, a stiff finger driving a damp trench through her stretch leggings. As Sienna swept the fingers of one hand through the waves of his hair, her other joined him down below.  Taking his probing hand, she drew it up to her belly, then stuffed it under the lip of her leggings, his rough fingers finding their unimpeded target instantly.

That was better.

Sienna grit her teeth and bumped her head back against the door, a ragged groan seeping from her throat. Moving quickly, she pushed him down by his shoulders to his knees and helped him tug her leggings down her legs and over one of her running shoes. It was bunched around the other ankle, but it was enough to allow her to spread her legs enough, giving clear passage for John’s fingers and mouth on her pulsing pussy lips.

“Oh, fuck,” she spat through pinched lips as she looked down gasping, watching the young clerk work so diligently on her below. Perspiration rolled down her face as freely as during her run, and damp strands of hair that had slipped from her ponytail clung to her cheeks and forehead.

In contrast to the robust, almost reckless thrusts of his fingers within her, his tongue stabbed and flicked at her lips and clit with deliriously expert precision. The guy’s tongue must have had good practice having to roll those “r’s” with that accent of his.

“My turn,” Sienna gasped, her whole body trembling. She could have let him go on, but they were short on time, and she wanted to taste his cock.

With little coaxing --Sienna was a teacher after all, and he was a good, somewhat polite, student-- John stood tall, bracing both hands on the door behind her as he leaned forward. She scooched down between him and the door, yanking apart the fly of his jeans, and pulling them down to his ankles. The moment she tugged down his underwear, his cock dropped out, heavy and stiff. With a zealous lick of her tongue around her lips, she took up his shaft and inhaled it in her warm mouth, humming with greedy satisfaction as she did.

John grunted and gulped above her, slapping the door with his hand as she dragged her teeth along the soft skin swaddling his hard cock. Shrouded from the light above by his body Sienna sucked with verve under the cover of shadow. She listened with delight to John grumble and curse in Spanish and smiled even as she cupped his balls in her mouth, slathering his sack with saliva. 

She pushed herself back up, her sweaty back dragging against the metal door. They kissed again, a messy, undulating merging of lips, and tasted their own bodies’ sweat and oils on one another’s mouths and tongues. John only managed to drop his shirt to the ground before their desperate need to fuck right now overtook them.

Hoisted from the ground with his hands around her ass, Sienna strapped her legs around his torso and arms around his neck, locked in securely to sustain the first, coarse thrust of John’s rigid cock. She pressed the back of her painfully against the steel door, gnashing her teeth and squeezing her eyes shut as he rushed her with quick, rattling strokes. 

“Uhhn, God…” she groaned aloud as she got an earful of the young man’s hot breath grunting and groaning.  

For the second time that night, adrenalin surged, endorphins kicked in and she crashed through that wall rewarded with explosive bliss. The way she was cinched in, with her gleaming muscles strong and resilient as she endured and welcomed every exquisite thrust, it was difficult to imagine she had completed a five-mile run just a little while earlier. She used her second wind to breathe filthy curses, spurring on her buck to fuck her harder, faster.

In the dark, dirty alley, they careened towards their climax. She felt his strong fingers dig into her ass, pulling her in every time he threw his hips forward. Their crotches smacked loudly, obscenely together, barely drowned out by their exhausted groans and moans. Digging the heels of her runners into the back of his thighs, her hands scrabbled at his slick, wet back and shoulders, trying to maintain her grip on his sweaty flesh.

Sienna found his mouth and clamped her lips over it with a raspy moan.  With one final, demanding thrust they both suddenly froze, save for the tremble upon their skin. As she pulled her mouth away, she breathed a shuddering groan, announcing the sopping wetness she spilled over his buried cock. “Ohh… God,” she squeaked, then gasped feeling her taxed muscles quiver and ache.

Not a second later, John let loose his own languid groan from deep in his gut. Sienna could feel every long, toned muscle in his body seize up as he unloaded within her, squeezing his butt to spurt every last drop of his cum into her slick, slippery hole. 

John went limp but continued to hold her up against the door.  Breathing hard, he muttered something in Spanish which Sienna figured was him thanking God and a few saints. Though weary and covered in sweat, she smiled and giggled. If he were her student, she would have given him an A+ for effort.

A minute later, they both hurriedly got dressed. Though they had been quick, they’d probably overextended the “Back in 15 minutes” sign by at least a noticeable margin.  

As Sienna readjusted her ponytail, she grinned and asked, “So are we square?”

John blinked and frowned, not understanding. 

She cocked her brow. “For the ice cream?”

After a moment, he smiled and rolled his eyes, then nodded back towards the front of the alley. “Come.”

She followed him back to the front of the convenience store where he asked her to wait as he went in.  When he returned, he handed her a bottle of sports drink.

Sienna nodded, still grinning, and accepted. “Thanks. I could probably use this right now,” she said, narrowing her eyes till they glistened, “Need to replenish the vitamins and minerals and fluids.”

“Anytime,” John said, shrugging and nodding. “I mean, anytime. You come by, I'll give you a bottle.”

She eyed him for a second. Then, as she turned away, she said, “Keep up with those studies. You’ll do great in Business.”

Taking a long sip of the cool, refreshing sports drink, she walked leisurely into the quiet, warm night, returning home to shower and go back to a contentful sleep just a little over an hour before the dawn.

--0--

Two evenings later...

Sienna strolled into the convenience store fresh and glowing after another late-night run.  

“Hello, ‘John’.”

“Hello, Ms.Sienna.”

She didn’t head to the back this time, just stopping by the candy rack momentarily before approaching the counter. She knew what she wanted. 

Behind the counter, John was already holding out the bottle of sports refreshment, grinning.

“Thank you,” she said, taking it from him. Then she showed him what she had selected from the candy rack. “Care to barter?”

John frowned and grinned crookedly, eyeing the cheap pack of gum. He appeared disappointed, asking, “That’s it? A single pack of Juicy Fruit?” 

Sienna chuckled then clucked her tongue as she shook her head at him. “Oh, Johnny,” she sighed as she stepped toward the door wagging the pack at him, “you have no idea of the value of a pack of Juicy Fruit to a woman on a hot night like this.”

Guess not everything could be taught from books.

She noticed him already unbuttoning his shirt as he slowly moved around the counter to follow her. Before she opened the door, she changed the single-hand clock on the “Back in” sign to read thirty minutes and flipped it over to face the exterior of the store. 

Then she ‘escaped’ to the back alley.
