Chapter Text
As the chief technology officer of LuthorCorp, Lena works from 7 to 7 if she’s lucky. Often, she is not. For the first quarter of the year, she has lunch and dinner at her desk, of course the food has to be delivered - she is not going to pick it up herself! The only steps she gets in are when she walks from her apartment to the Uber, to her office and from her desk to the toilet.
On a particularly late Tuesday night, she finds that, aside from the cleaners, she is the last person in the office. She uses the bathroom and as she is exiting, she catches her reflection. Despite having been an athlete growing up, she finds that her adult body does not live up to her standards. She still thinks she’s attractive but, being a perfectionist, there are so many areas she can improve on.
Her stomach was soft, almost pudgy, her arms were no longer firm and her butt was beginning to take the shape of her chair cushion! Before she can find more imperfections, she strides back to her desk, sends her final email for the night and signs up for personal training sessions with a gym near her apartment.
She fills out the form as quickly as possible:
…
What are your goals?
☑ Strength
☑ Flexibility
☐ Post-Maternity Body Snapback
☑ Mobility
☐ Crossfit
☑ Weight loss
☐ Weight Gain
For personal training sessions, what time(s) works best for you?
☑ Before work (5.45 AM to 8 AM)
☐ During the day (8 AM to 4 PM)
☑ After work (4 PM to 9 PM)
It’s 8 PM on a Friday and Lena rocks up to her first training session wearing her old workout clothes: black yoga pants, a sports bra and a blue moisture-wicking crew t-shirt. It’s not the prettiest outfit but it will work. She wears the moisture-wicking t-shirt because she knows she’ll need it after over a year away from the gym.
She stands next to the reception and coughs to get the receptionist’s attention. The receptionist looks to be a mid-20s girl who is not happy to be working on a Friday night.
“Can I help you?” The receptionist asks as she chews her gum.
That’s strike one against the gym.
Lena replies, “I’m new to the gym. I had a session with a trainer for 8.”
The receptionist makes a call and turns back to Lena, “Here’s your tag. Your trainer will show you around the gym.”
“Thanks.” Lena answers coldly.
After a minute, a blonde woman walks up to reception. Lena can’t help but study the blonde’s figure: she has the body of an olympic athlete. With lean muscles, a sports bra and tights that hug every fibre and curve of her body–okay maybe working out isn’t the only thing Lena hasn’t done in over a year. Lena does her best NOT to look at the particularly large bulge.
The blonde with the sculpted body turns to face Lena but Lena isn’t even processing her words.
“Huh?”
“I’m Kara, I’ll be your trainer. I was asking if you got a tour of the gym yet?”
Lena shakes her head timidly. She is the CTO of a Fortune 500 company and she can’t express herself in front of someone she’s paying.
Kara puts on what looks to Lena to be a pity smile and starts giving her the tour. The gym looks to be a standard gym for the 2020s, although it has more weight machines than Lena expects. She doesn’t have much to complain about, save for the one or two obnoxious neon signs.
Lena takes every opportunity to gaze upon the female Adonis.
Whenever Kara turns to point to a machine, Lena watches how her bicep flexes. When Kara turns her torso, Lena appreciates the flexibility and prominence of Kara’s abs. When Kara bends to show the different weights of the medicine balls, Lena can’t help but notice Kara’s strong thighs or sculpted ass.
Lena feels like a creep. It’s not that she’s staring but she can’t help but notice. It’s like being stuck in an elevator with peak Arnold Schwarzenegger. There’s only so many places you can look!
“So what’s your goal?” Kara asks, her blue eyes are focused on Lena’s.
“Well, I work corporate and I’ve gone pudgy.”
“You look to be mostly in shape.”
“Well, with my clothes off I remind myself of a melted candle.”
Kara laughs, “I think you’re being really harsh on yourself. You might not be where you’d like to be but you still look great. Were you athletic as a teen?”
“Yeah, I played volleyball.”
There’s a gleam in Kara’s eyes when Lena says that.
“You’ve probably retained a lot of muscle from that time. You said you work an office job right? You’ve probably lost flexibility from the sedentary lifestyle but you can easily get that back.”
Kara guides Lena to the yoga area and has her do some basic stretches. When Lena bends over, she winces.
“Where does it hurt?”
“My lower back.”
Kara places a large warm hand on Lena’s lower back, “Don’t do anything if it hurts. Try to get into downward dog, do whatever is comfortable.”
Lena does her best downward dog but her knees are bent. Kara’s palms run from her knees up to the top of her thighs, dangerously close to her buttocks. Kara squeezes her thighs.
“Okay let me see you do some squats.”
Lena does as instructed.
“I see your problem. Do you have a lot of lower back pain?”
Lena sighs as she finishes her final squat, “Lately, yes. By lately, I mean the past two years.”
“When you work a sedentary job, sitting for a long time can weaken your glutes. So we need to work on your glutes and your core. While also working on your flexibility along the way.”
“Can I do that while losing weight?”
“You don’t need to lose weight.”
“I can’t fit into my old clothes.”
“Have you ever heard of something called body dysmorphia?”
Lena puts her hands on her hips, “Are you a therapist or a trainer?”
Kara shrugs, “I don’t recommend it. You need strength training, not rabbit food and cardio.”
Lena looks unconvinced.
“Give it a try for say 3 months. One-on-one sessions with me. And if you don’t notice any body recomposition or improvement in your back pain, then try something else.” Kara puts her hand out, “Deal?”
Lena’s core pulses when Kara says “one-on-one” and she shakes Kara’s hand.
Lena goes home with a meal plan and a workout routine suggested by Kara. While lying in bed, she buys an Apple Watch and some cute workout sets.
FIRST WORKOUT
Two days after her induction with Kara, Lena has her first training session. To her immense disappointment her new workout clothes have not arrived, but her Apple Watch has!
Kara has Lena warm up with a short walk and then stretches.
They spend a lot of time stretching Lena’s legs. In one stretch, Lena has to try touching the ground while her legs are apart. Lena almost jumps when Kara gently taps her foot with her foot, Kara is inches away from Lena’s ass.
While Lena is doing bench presses, Kara acts as her spotter. Lena’s face is quite close to Kara’s bulge but this seems to only fluster Lena, meanwhile, Kara remains focused on the workout.
Kara never calls Lena by her first name. It’s always ‘Luthor’!
“Nice hair, Luthor. Did you do that yourself?” She asks one day when Lena rocks up with french braids.
“Great workout Luthor, I know it doesn’t feel good now but I promise you’ll feel better later.”
“Awesome job Luthor, you’ve hit your step count and your macros!”
It’s not insulting to be called by your last name but just once, once pretty please, Lena would like to hear her name slip out of Kara’s lips.
FIFTH WORKOUT
Lena rocks up to her workout wearing a matching set: a cropped long-sleeve jacket, sports bra and waist-high shorts. She puts her hair in a ponytail and, only because she’s ovulating, she wonders what it would feel like if Kara grasped Lena’s ponytail with a strong calloused hand and made Lena taste herself on Kara’s cock.
Note to self, she thinks, buy a new vibrator.
Kara is fair but she is not a pushover. When she spies Lena taking small shortcuts during her stretches she forces Lena to start all over again.
When Lena groans Kara has a quick response, “You pay me to make sure you have a safe and effective workout. Safety first, Luthor.”
Kara decides to take a more hands-on approach. When Lena is lying down with her left knee to her chest, Kara kneels next to Lena and pushes on Lena’s thigh to ‘make her feel the stretch’.
“I’m not sure if you’re really feeling the stretches.” Kara sighs.
“I think I’m feeling it! Or at least I feel something.”
Kara is firm as she maneuvers Lena’s body; with her left hand, she pushes Lena’s leg against Lena’s chest, making sure to lean in. Kara rests her right hand on Lena’s thigh, close to Lena’s pussy.
Lena stares at the ceiling, secretly praying that Kara can’t feel the heat emanating from her pussy.
“Do you feel that?”
Lena nods.
“Now, let's do the other leg.”
Kara does the same thing with Lena’s other leg.
Then as if nothing happened, Kara goes on to explain the different muscles in the legs and how the workout routine engages said muscles.
“Wanna try something a little advanced?” Kara smirks, “I don’t think it will be a big challenge for you, given that you grew up flexible.”
“Grew up flexible?”
“I mean, playing volleyball. You must’ve had to stretch and stay flexible. Anyway…”
“Sure thing! Our coach always made sure we stretched before and after a game. I even used to be able to do standing splits.” Lena adds before turning slightly red, she didn’t mean it like that. How would her employees feel if they saw her getting all hot and bothered by her trainer?
Kara is unfazed, “Great! Let’s see how far you can go. I’ll help you out and, please, speak up at any moment if it gets painful.”
Lena lays on her back and, with her left leg on the floor, tries to get her right leg as close as possible to her chest. Kara keeps one hand on the left leg and, with her other hand, directs Lena’s right leg.
“I can stretch more than that!” Lena says and she brings her leg closer to her chest.
Kara seems impressed. But that doesn’t last long.
“Oufff!”
“Here, here, we’ll hold it right here.” Kara pulls Lena’s leg back a few inches and helps Lena hold it in place.
When Lena looks down, she finally notices how close Kara’s bulge is to her crotch. She quickly looks up and try to focus on the stretch. And really “feeling” the stretch, whatever that means. If someone were to walk in they would see Lena with her legs out and Kara in between, looking like they’re imitating… well.
The remainder of the workout is not as eventful. Kara is the perfect professional; she helps Lena wipe down the machines when they’re done and wishes her a good night.
When Lena is in bed that night, she feels like she’s ready to explode. Heat and frustration coils between her legs. She’s seriously going crazy, she’s purchased six new workout sets in the past two weeks!
She sighs, opens her phone and searches for “blonde muscley dickgirl”. After thirty minutes, she can’t bring herself to orgasm. Frustrated, she puts her phone on the wireless charger and tries to sleep.
Later that night
In her mind’s eye, Lena sees Kara in an abstract gym room. Kara takes off her jacket, the light makes her body glisten. Kara turns to face Lena as if she knew exactly where Lena was.
Kara’s eyes twinkle and there’s a slight smile on her face.
Kara takes her tanktop off as she walks towards Lena, “Let’s see how far you can go. Given how flexible you are.”
By the time Kara finishes speaking she’s standing in front of Lena. Kara looks down at Lena.
Lena smiles.
Kara descends upon Lena with a ravenous kiss. The desire is primal, Kara pulls at Lena like Lena might slip through her fingers. Kara’s rough hands pull at Lena’s clothes until Lena is totally nude.
The hazy scene plays out in Lena’s mind, she feels Kara’s hands, roughened up by weight lifting without gloves and god knows what, roaming across her body and slipping inside her. She can almost taste Kara’s pert breasts or Kara’s beautiful cockhead when she takes Kara’s into her mouth. She groans out loud when Kara sinks her length down her throat.
When Kara thrusts into her cunt, Lena can almost feel the girth that Kara’s bulge always hints it. And Kara knows exactly where Lena needs it. Kara strikes at it with her cock, Lena barely has time to admire the veins that lead from Kara’s abs to her dick as Kara holds her and begins bouncing her.
It is glorious.
Much like Lena’s first horse riding lesson: it is thrilling and has her bouncing up and down. Lena tries to suck on her bottom lip, tries to stay quiet but the sensation is overwhelming. It strikes her body like lightning. She can hear herself cum out loud.
Lena wakes up to her heart racing, her pussy pulsating and finds her hand in between her legs. Her mouth forms a perfect ‘o’, she has to clean up: she can’t let her cleaner see that she squirted in her sleep.
