(This is a short standalone story that I wrote for the

On The Job Challenge 2025

. It was a lot of fun to dream up and write. I hope you enjoy the whimsy, I have to admit I giggled as I wrote it. I did not spend a lot of time on it, so the writing is a bit rough. Enjoy!)

Another day, another problem. I walk to my paper strewn kitchen table and boot up my laptop. I begin to type and am again irritated at the silicone covered keys. My entire laptop is in a waterproof case, a necessary precaution in my chosen career.

I scroll through emails from designers, coordinators and builders. I toss some spam into the trash folder. 'Hi, I'm so and so and I saw your profile and you're so hot!'.

I spend the next hour working through correspondence about the Leviathan project. It is the biggest project I've ever led and when complete will be the largest ever built. Stress is mounting as it's only a few days away from testing.

A new email pops into my unread folder and I'm about to delete it as it looks like another porn scam.

The subject line reads, 'I'm excited to meet you, I'm Brittney!'

But the word Leviathan is in the first sentence of the email so I pause and read.

'Hello,

I am honoured to be a tester for your Leviathan project! I have experience testing similar but much smaller structures, some even designed by you!

You create the most unique and exciting experiences and this one promises to be the best yet. I have booked my flight across the country and am waiting expectantly for the testing day. I hope it is not delayed, my agency says they do not know.

I'm so excited to meet the man behind the machine!

-Miss Brittney Laroux'

I type out a response and read it a few times before hitting send.

'Hello, Miss Laroux.

I am flattered by your kind words! I am glad that you have enjoyed my previous work and look forward to your assessment of Leviathan. It is has been a delightful challenge and I hope it exceeds your expectations.

You say you are travelling across the country, I am surprised your agency would send you so far. I hope the destination is not disappointing.

So far the project is on schedule. With only a few days left I expect there to be no issues. If there is a delay, I will send an email so you can adjust your travel accordingly.

See you on first water day!'

I search through our personnel database and find her information. She has been an alpha and beta tester for a few years, her clearance photo shows a beautiful young woman in her early 30's. Short red hair with heavy freckling on her nose and cheeks. Her cheeky smile indicates a vivacious personality. I smile as I think about meeting her.

Two days later I receive an urgent call from the foreman. A water main has ruptured and it will take three days to fix. I growl about the delay and demand to know how it happened.

Apparently a small section of the line was cracked and went unnoticed until the system was fully pressurized.

I call a few people on my team letting them know of the delay, I send off a form message informing all the PR leads and media of the delay.

Eventually I get the repairs in motion and am about to close my laptop when I remember Brittney. I quickly send her a note saying it has been delayed three days.

The next morning I wake to dozens of messages and groan. One stands out to me and I read it first.

The subject line reads, 'Well shit, know any good places to eat around here?'

I can't help but smile as I read Brittney's email. Her informal message indicates she has already flown here and wonders if I can offer advice on how to spend the time. On a whim I offer to take her to dinner tonight. I press send before I can reconsider. I tell myself it's a business dinner, spending time building relationships with staff and clients is important after all.

She is unmistakable as she walks through the casually elegant entrance of the restaurant. Her red hair is longer than in her photo, it hangs just below her shoulders. She is wearing a pale green sundress that sways at her hips. Her bright green eyes immediately spot me. She waves, smiles brightly and practically bounces over to me.

Her expression and energy are infectious and I find myself feeling giddy as we sit at the table. She speaks excitedly about Leviathan and asks about my other projects; she also seems to breathe only when she stops speaking. She listens so intently that I feel as though she inhales my words.

As dinner progresses I find myself enamoured with her. She is passionate, intelligent and graceful. Her engaging conversation and intense eye contact make me feel as though I am the only person who exists to her.

As we are enjoying a light dessert she asks if we can meet tomorrow at the project site. I tell her that I'd love to show her some details she wouldn't normally see.

The next day at the job site I am distractedly thinking about how she would look moving along the massive structure. Would her expressions match what I hope to cause?

I am pulled from my reverie by my phone ringing. I hurry off to a quiet area to speak and Brittney's high energy voice is laughing as she explains how she became lost in the park. I offer to pick her up.

I grin all the way to the park and see her sitting on a bench reading a lurid novel. She looks up as I call her name and she walks quickly over to me.

She tosses her book into her purse and says, 'Thank you!'

She perches on the seat of my car looking around. She immediately turns up the stereo and I chuckle as her eyes widen.

'I didn't peg you for a metal head.' She admits. 'You seem more like a cognac and classical kind of guy.'

When we arrive at the site I give her a hard hat and we walk around the site. Our hands brush as we walk between thick metal posts, I glimpse high up her thigh as she bends and leans forward to get under a piece of the framework.

She points to large boxes attached to the hollow tubes and I explain that I have added an audio sensory aspect to Leviathan and her eyes widen.

'No one has ever done that before!' she exclaims.

I preen at her words and grin, 'I know, I'm hoping it will enhance the experience. See how it is placed just before this drop? The sound should rumble through the area.'

She glances around us and seeing no one, takes a step closer to me.

I'm looking into her shining green eyes when she softly speaks, 'I'm experiencing some of that deep resonance now.'

She presses her body against mine and my cock stirs, she grinds against me and I wrap my arms around her waist, hands on her ass.

I kiss her neck and shoulders, pressing her ass into a rhythm with my gently rolling hips. Her hands press into my back. Her green eyes pin me as she raises her lips to mine.

'BOSS!' a shout from across the site breaks our moment and I sigh.

'Back to work. Do you want to stay and see more?' I ask as we walk to the foreman.

The foreman comes barreling towards me the moment he sees us and amidst a stream of curse words I understand that the water main is fixed but there are other issues cropping up because of it.

Brittney touches my arm and I turn to her.

She says, 'I think I should let you get back to work here. Maybe we can meet up later?'

I consider asking her on another dinner date but I know I will be spending hours at my desk tonight.

'Would you like to come to my place? We could order takeout and get to know each other a bit more.' I add sheepishly, 'I need to do a lot of recalculating and can't really take time off for a dinner date. But this way I can work until you arrive and then spend the evening with you.'

She agrees, I take her to her hotel and I immediately go home to work. The emails are piling in. I have to fast track permits and forms in order to have the project done quickly. I'm mentally drained when I hear the knock on my door. I look at the clock and swear, I didn't even give myself time to shower.

Brittney is dressed in a lavender blouse and colourful skirt that is quite jarring with her bright red hair. She greets me and I guide her inside.

She asks me about the drama at the construction site and whether or not she will need extra nights at the hotel. She walks over to my kitchen table and smiles. The table is covered in papers, folders, books, reference photos, a coiled blueprint and my laptop. And a few coffee cups.

We talk about the project and I explain that it should be done only 3 days late. She winks at me as she says she'll have to make the most of the mini vacation.

The evening with Brittney runs late into the night and we find we have a lot in common, we laugh easily and speak freely as though we have been friends all our lives. By the time she insists she must go home my hair is rumpled and my shirt half unbuttoned. And I have had a raging erection for nearly an hour as we kissed and groped each other on my long couch.

The next night is the same, we talk and laugh and end the night with an intensity bordering on frantic as we explore each other. As she is straightening her hair and clothes before leaving I tell her that tomorrow is first water day. If all goes well she will be able to test it in the afternoon.

She nods in acknowledgement, suddenly all business. 'I'll be ready.'

She leans forward and kisses my cheek, 'Thank you for another exciting evening with you.'

-- -- -- -- --

I pace nervously at the top of Leviathan, the longest and second tallest waterslide ever built. I designed this with an elevator and I keep glancing at the doors. My assistant, lead contractor, PR director, and 2 members of the press stand on the platform with me. The water flows in a torrent down the slide and all the tests have shown it working perfectly. Now to test the human experience.

Brittney walks out of the elevator, her bright red hair is slicked back into a ponytail and she is wearing a bright blue wetsuit. I smile and hold out my hand to her, she grasps it in a handshake and beams at the cameras.

'I'm very excited to be the first to experience this masterpiece! Is it ready?' She asks, confidence and excitement playing in her words.

'We are ready for you, I will meet you at the bottom before you arrive.'

'I like your confidence,' She grins at me, 'You expect the run to last a full two minutes then?'

'If the instructions are followed, yes' I grin back at her.

She nods, 'I always follow the rules the first time.'

She sits on the large platform and water swirls around her legs, she looks back at the flashing cameras, smiles, crosses her arms and lies down. The water carries her down the slide and I hear a long peel of laughter flow back up from the tube.

We all step into the elevator and are at the base of the slide before her. The bottom of the slide is a full 5' above the water and torrents rush out. I hear the rhythmic bass effect hopefully creating vibrations in the water just before each sudden drop. I posture myself and smile for the cameras as I wait. And then I can hear her excited laughter as she nears the end of the slide.

Her blue form flies out of the tube and hits the pool in a splash. Everyone claps and cheers and Brittney swims to the exit of the pool, absolutely beaming. She walks straight up to me holding out her hand, she beams at me and then pushes me into the pool.

Everyone cheers again, I pretend to sputter and struggle as I swim to the exit while she laughs gleefully. It's tradition for the first to go down a new waterslide to splash the designer with water if it is a good one. Being yanked into the pool means it is fantastic.

The rest of the day is spent with her and a dozen other testers going down the slide over and over as my crew fine-tune the details. The testers fill out questionnaires after each ride and I take copious notes about their experiences, minor tweaks and adjustments are the only concerns they have. They all comment that the bass rumble is a unique addition that heightens the experience considerably.

Nearing the end of the day Brittney tells me that she would like to see me again before she flies home but that tonight she has paperwork for her agency and is quite exhausted. Stealing a quick kiss before she goes I request that we meet here tomorrow evening after everyone has gone home for the night. She agrees and I watch her taxi leave.

A round of drinks at a nearby pub later and I'm at home. I lay in bed and relive the past few days. It has been a wild ride, the utterly unexpected appearance of a stunning woman in my life combined with the intensely satisfying results of 2 years of work has my libido spiked. My hand strays to my cock as I think about Brittney today. Her flushed face, her wild laughter, her grin as she pushed me into the pool. The kisses, grinding against her near the waterslide at the site, her hands all over me these evenings on my couch. I find myself stroking my cock and when I imagine my most intense fantasy, she is the woman in it.

-- -- -- -- --

That fantasy plays out in my mind unbidden all the next day. I'm in a state of constant arousal and can't wait to see Brittney again. Of course it seems as though everyone needs to talk to me at the end of the day. Finally I am left alone on the site. I look around and smile at my creation. My phone buzzes in my pocket and I walk to the locked gate of the main entrance. Brittney is standing outside in a long skirt and button up blouse. I unlock the gate and she steps in, smiling at me.

We walk around the site talking, stopping occasionally to kiss, our bodies always touching. We sit on a bench near the end of the waterslide, the torrent of water muted by clever design. Our talk moves to more intimate subjects, our desires and dislikes and eventually to fantasies.

'I've always wanted to kiss in an elevator.' She says, 'I know it is barely adventurous but it's something I've just never experienced. Have you?'

'I have.' I glance at the elevator up to my waterslide but hesitate to say anything. My fantasy is definitely adventurous.

She pushes my shoulder, 'What are you holding back? Surely you have a fantasy or two you can share with me?'

She leans in and speaks in a low sultry voice, 'Maybe we can fulfill each other's fantasy, I'd love to ride your elevator.'

I whisper in her ear and her eyes light up. 'Yes! Absolutely yes!'

We walk to the elevator and once inside I cage my around her as we kiss. She moans and grinds against me, I press her back against the wall and our tongues dance. The ride is all too short but we stay in the elevator long after it has reached the top.

She pulls open my shirt and tugs it off me, she rains kisses up and down my chest as I pull her shirt over her head. She dips to her knees and undoes my belt before we move onto the platform of my waterslide. She pushes me against the railing and yanks my pants down, I kick them off and before I can blink her lips are wrapped around my cock. Hot wet heat suddenly slurping at my tight head has me holding tight to the railing, trying to keep my hips from bucking into her mouth. She strokes my cock in time to her head bobbing and she is doing maddening things with her tongue.

I'm about to ask to her stop, that I have to cum soon when she pulls away. She licks her lips as she looks up at me and then rises to her feet. I move her to lean against the railing near the slide and drop to my knees. I grasp her ankle and gently guide her foot to my shoulder. Her dress lifts and I feel my cock throbbing as her mound comes into view. Soft red curls amidst pale lightly freckled skin and her parted thighs display a sheen of moisture between them.

I press my fingers to her folds and slide along the seam, my fingers stroke gently across her entrance. I lean back just far enough to look into her eyes as I suck her moisture from my fingertips. I let my eyes close for a moment as I savor the taste that is uniquely her. Her eyes are clouded in lust and I chuckle as her hand presses my face back between her thighs.

I tease her as I explore her, finding the rhythm and movement she likes. Her hips buck and her hands press my face, moving me where she wants me. I sink a finger into her and she moans. I slide in a second finger and I moan, she feels so good, tastes so good.

When she is squirming and pushes at my head I reluctantly pull away from her mound. I kiss and nip her thighs while she lowers her leg from my shoulder. She pulls her long skirt off and lays it on the floor and then presses me down to the floor on my back.

I stare up at stars and her gorgeous body above me, the moonlight dances off her fair skin and her red hair creates a fiery halo framing her face. She throws her head back and with agonizing slowness she lets me enter her. Inch by glorious inch my cock is consumed by her tight slick heat; I groan before she has even fully taken me into her core and grasp her hips.

She leans forward pressing her palms to my shoulders and rocks against me. I watch her face as I hold her, letting her set the pace she wants. When she raises her hips the tip of my cock plays at her entrance, I thrust slightly teasing the head of my cock into her and she trembles. I pull her down to rest on me and pour my passion into a kiss, we grind and shift against each other quickly finding the synced rhythm I've only experienced with long term lovers.

She shifts onto her side and I pull out of her for a moment, I caress her body as she moves under me and with long slow strokes I tease her clit with my cock head until gliding back into her fully. I roll my hips as I thrust, seeking out the spot that might make her moan. I feel her nails dig into my back and slow my movements pushing deep inside her. My patience and control is rewarded by her clenching around my cock and moaning my name.

She whispers, 'I'm close.'

I'm grateful, I'm barely holding off my orgasm.

'Are you ready?' I ask.

Her response is to push on my shoulders and I move to lay down in the entrance to my waterslide. She mounts my hips and sinks hilt deep, my breath escapes in a quick huff and I wrap my arms around her. She lays down on top of me and grinds as I push off and we begin the journey down the waterslide.

The rush of water, the pounding bass audio and our spiked arousal has us crashing into each other. Less than half way down the slide I clamp her to me and feel my body explode inside her. She laughs and cries out as her body responds in kind to the chaotic sensations. We are swirled around and down the slide, water pummeling us as we are pulled in uncontrolled and wild motion. Our bodies thrash together along the final few turns and drops, the thrumming bass amplifying our orgasms as they pour through us. We desperately cling together until finally we hurtle through the air. Bodies pulled apart, we splash into the pool.

I am back at the surface a moment after her and our mad laughter rings out across the empty park. I pull her to me and we swirl and dance beneath the torrent of water for a moment before swimming together to the nearest ladder. She climbs up and sits on the edge of the pool. I stand beneath her and watch drops cascade from her hair down the soft planes of her cheeks, the mix of moonlight and water create the image of a shimmering water goddess and all I can do is stare.

'Want to go again?' She says, grinning.
