Chapter 7: Thieves and Confinement

Cassie gazed at her phone early in the morning reading an email from Mr. Kim, the sports director at her university whom she stole from. Just the notification alone had her heart racing. The email had apparently hit her student account the day before.

Exercise Regime Update - Cassie Bergh;

Hello Miss Bergh,

As per your request, I have found a timeslot at our athletic center in room B456 for your continued use. You will be expected to be there Wednesdays @4pm - 7pm, effective immediately. Attendance is mandatory.

Her date with Mia was today! There's no way this would work. Oh my god. I'm being scheduled for... I can't believe how he worded this... "continued use." Literally no notice. He's treating me like a toy he can just plug into his schedule!

Cassie tried to ignore how wet she was becoming. One hand slid down under her pajama bottoms and rubbed her clit as a series of invasive(?) thoughts trickled into her head. A part of her actually wanted to go please Mr. Kim. He was letting her off the hook; she had stolen from him and this was a way for the two of them to come to an agreement. Her body for his silence. Cassie imagined handing over her pussy like a wallet he could spread and count to make sure it was all there. It was only fair.

What the fuck am I thinking about?

She slid a finger into her pussy, then two. He could do anything to her in that window. And if she wanted to please him quickly, she would need to bring condoms, and wear something slutty (to change out of). What if he came inside her? Would she have to walk home with his cum leaking out of her?

Cassie couldn't bring herself to fish out her dildo and instead used two hands to play with her clit and rub her pussy. She needed to organize her thoughts. A notification hit her phone from facebook; Mr.Hall had sent a friend request (her neighbor from the cosplay shop).

Fuck, I'm such a slut.

I need Mr. Kim to take me to his house. Or else he's just going to hang this theft over me forever. Like a carrot on a stick, except his cock is inside me, pumping his cum into me week after week. A thrill went through her at the thought of becoming his secret little university cumdump.

Damnit! Mia is going to be so mad I'm skipping out on her for Mr. Kim. If I'm going to get out of this, I need access to his home, his belongings, his secrets. Cassie started grinding against a pillow and slapped herself, immediately feeling like an idiot. She needed a man to slap her, not her own wimpy hands.

I should be thinking about school. Dad is counting on me to get good grades. He'd lose it if he knew what I've been doing... Dressing up in little slutty outfits, licking my swim captain's feet, swallowing my sport's director's cum.

Cassie bit her lip as her orgasm rose.

Mia was going to be so mad! Should she warn her? I want her to step on me. Cassie held her breath and squeezed her throat as she pictured Mia's reaction. This korean goddess with her adorable pouty lips and toned body that just demanded submission. Would she put on heels and step on her? Would she humiliate her in front of her servants? Walk her down the street like a dog?

Licking her fingers, Cassie imagined being forced to lick Mia's toes as her servants watched, feeling their embarrassment for her like hot wax being poured down her spine.

"Ummnhh," Cassie whimpered as she orgasmed onto her pillow, quivering with her fingers in her mouth. The regret of post-orgasm clarity quickly subsided; she was only daydreaming afterall. Whatever was going to happen today couldn't really be her fault.

So call it pre-schedule jitters, blackmail anxiety, whatever you want, Cassie ended up skipping class and hiding out in her car parked in the university staff parking. What was she doing? Just watching. Mr. Kim's Prius pulled up near the front and he got out and kissed his wife goodbye.

She was cute for a woman in her forties: short black hair, big tits, a little out of shape. And before Cassie knew it, she was following her down the street to a Superstore feeling like some sort of criminal. It was strange to think what she was literally doing, so she didn't, and nearly missed Mrs. Kim getting back into her Pruis.

Around nine a.m. then, Cassie watched Mrs. Kim pull into the driveway of her home and a boy rushed out to help bring in the groceries. He looked around Robbie's age, but tall and athletic.

Mr. Kim's house was nice...

Cassie must have been really frustrated or desperate because instead of returning back to the university, she got out and decided to walk by. Looking for potential targets, perhaps. The idea of stealing from Mr. Kim had become like a secret fantasy to her, and the fact his family didn't know what she looked like pressed all the right buttons. What could it hurt anyway?

"Hey!"

"Hello?" said Jason.

Jogging up from the sidewalk, this gorgeous blonde gym-bunny just inserted herself into his mom's car, pulled out a bag of groceries and smiled. He knew girls were starting to come onto him because of his muscles, but damn. And damn.

"Let me help," she said.

"Sure. I mean, yes, grab that bag."

Be assertive.

She was wearing black gym shorts that absolutely stuck to her ass as she bent over. It was everything he could do just to resist slapping it. Fuck, was he supposed to slap it? Women liked that, didn't they? When she finally turned back she tilted her head and gave him this innocent, confused look as if he'd missed his opportunity.

"Aren't you going to grab a bag?"

He grabbed the remaining three and his mom's purse.

"So. You got a name?"

"It's um, Lindsay."

"Um Lindsay?" he mocked.

"Yes."

"Well, does Um Lindsay have a number or an insta?"

She dropped the grocery bag off at his front door and rolled her eyes, those big tits bouncing in their sports bra, but she did pull out her phone. It's fucking working!

"It's .. xxx-xxx-xxxx ..."

"Wait, lemme—"

"Jason?" His mom shouted from somewhere inside the house. "Jason, who's there?"

"I've gotta go, bye!"

Fucking numbers! Jason's eyes were glued to her as she jogged back to the sidewalk, reciting the numbers in his head. A real man doesn't chase though. Females do the chasing. After a few hours he sent her a 'hey' and then went back to his free-weights in the basement praying it was the right number.

She sent him a winky-face a few moments later.

Cassie got lunch with the twenty she stole from Mrs. Kim's purse (it was sitting in the Prius) and killed time at Burger King. Was she juvenile for feeling this excited from stealing a mere twenty dollars? Yes. But the satisfaction from taking it right from Mr. Kim's wife was immeasurable. Chicken strips had never tasted so good.

While she was buying condoms for her 'appointment' from the gas station on the way back to the university, however, she remembered rather darkly that her midterm was tomorrow. And she hadn't opened the textbook all month.

"Just the condoms?" asked the cashier.

Cassie nodded, not wanting to look him in the eyes.

I'll cram when I get home. Are these condoms the right size, though? Mr. Kim kinda has a big dick. But like, not thick. Should I get different sizes? I can't go back in there and buy more, the cashier's gonna think I'ma prostitute. Uhg, whatever.

She hopped back in her car.

At four pm Cassie opened the door to room B456 in a little pair of gym shorts and baby blue sports bra with her hair tied up into a ponytail by an equally baby blue scrunchie.

B456 turned out to be a tiny specialized gym like the ones you'd see in medical exam videos with music playing a mashup of things she'd heard before, but with more reverb? Nobody's here. Maybe Mr. Kim had lost his nerve and just let her workout on these machines; maybe he got busy with work and couldn't make it to his own appointment, though that seemed unlikely.

Cassie took a seat at one of the machines as a loud switching noise hit and all the lights went into power-saving mode.

"Um. Hello?"

Weirded out, Cassie tried the door and found it locked. The music, however, still played, which was something at least.

"Hello, Miss Bergh," Mr Kim said through the speaker. "This gym will be your personal training facility for the rest of the semester. You will be expected to practice on the equipment following the regime that I'm sending to your email. I will come by personally to unlock the doors at 7pm."

Are you serious right now?

Cassie rolled her hips to the side and looked around the room for a camera. There were many, each blinking green.

"Mr. Kim, this is weird as fuck. I'm not a guinea pig. What if I have to go to the bathroom?"

"There is a pan by the squatting rack."

"Mr Kim!—"

Before she could yell at him though another beep sounded off indicating he'd left. Fuck no! No, this is way too weird. But none of the doors would open. Cassie glanced at her phone which somehow had no connection and looked at the clock. She was here till 7pm. She was just going to wait it out.

"I suggest getting started, Miss Berhg. Or I will have to proceed with criminal processing through the school."

"Okay! Whatever... I can work out."

Did he lock the windows, too?

"Now, Miss Berhg."

With a huff, Cassie opened her email up and started the list from the top.

[30 minutes Treadmill] [100 Butterfly Kicks] [60 x 30 lb squats] [2 minutes Plank] [32 x 5 lb flies] [40 x 90 lb hip thrusts] ...

If this is really what he wanted, she'd do it. Criminal processing... Imagining her dad's reaction sent a shiver down her spine. Working out was hardly punishment.

In about an hour she'd already found a good rhythm.

But it was strange — similar to when she was in the pool, it felt good in here. At some point she got a second wind and just stopped thinking altogether. The dim light might have also been a factor. She felt alone, inside herself, more connected to her body than before. Sweat poured down her neck, stomach, and legs, and time just drifted by.

At the two hour mark the room felt too warm so she decided to take off her shorts and workout in her panties and bra. So sweaty. Maybe coming to these sessions once a week would be a good thing? There was a pair of headphones hanging by the door that were connected to the overhead audio she decided to put on to really get the beats flowing...

Part II: Training

Mr. Kim slipped into the training room and walked right up behind Cassie sitting on the hip abduction machine. In her current state she would be blissfully unobservant. So dumb. Seeing her up close sent a roar of lust into his chest; her heavy breathing, sweat trickling down her neck to her chest, pushing open her legs wearing nothing but a pair of tiny black lacy panties tapped into whatever primal part of his brain demanded penetration.

He leaned down just to smell her then, surprised at his own restraint, knowing full well he finally had her where he wanted her. She smelled... divine. Designed for sex as all young women were; a mix of floral shampoo and feminine deodorant obscuring her musk. The gym was probably full of her pheromones testing his willpower, bidding him to act in an uncivilized manner. His audio files, however, would be doing the same to her.

Mr. Kim liked his lips and swiped open his phone to switch her audios back over:

MINDFULNESS SUBLIMINAL HYPNOSIS

Video (7) loops:

[Strong] Loss of mental focus when interacting with Mr. Kim;

[Strong] Pleasure and satisfaction from pleasing Mr. Kim;

[Strong] Arousal and pleasure from stealing from Mr. Kim;

Limit Reached (3)

Cassie paused at the abrupt music change, but didn't really mind the change of track. Wait, was someone behind her?

"Oh my god, Mr. Kim!" Cassie jumped right the fuck out of her machine. Her headphones flew as she spun around, though the music was still playing overhead. Mr. Kim was literally standing right behind her in his blue button-up shirt and slacks with his phone out. Did he take any pictures? Why did I take off my shorts!?

He raised his hand indicating everything was all right, but then seriously when did she take off her shorts? Twisting this way and that, Cassie tried to cover herself.

"Aren't we a bit past that, Miss Bergh? Remember the Quantum movie? Remember our last meeting?"

Cassie looked around the dimly lit room as the word settled into her head. He was right. He'd seen her tits already and she'd be lying if she thought she didn't look good. Slowly then, heart still running track-and-field, Cassie put her hands on her hips and regained composure. He did face-fuck me last time...

When she tried to formulate a plan though, she kept getting distracted by stuff? Like, rather quickly, another thing would take its place. She found herself squinting to maintain focus. Mr. Kim had a tent in his pants. Her skin felt so smooth. She needed to get this over with without losing too much of her dignity — was he always taller than her? The music was soothing.

"Hello, Miss Bergh?"

"Mhm. Why don't you take your stupid dick out of your pants already. Get this over with."

"Not interested in finishing your regime?"

Is that what he wanted? For her to finish her regime? Cassie shifted her hips and looked around for her phone feeling a bit like she was drunk, but she hadn't swallowed anything... If he wanted her to finish the regime though, if that's what would please him, she'd do it.

Fuck, I can't think straight. Can I just sit on a dick, please?

"You look confused."

"I can't find my phone."

"It's in your bra."

Oh god. This situation was just so— Cassie pulled the phone out from her bra and turned away embarrassed.

"How about a massage? You seem overwhelmed."

"Yes, please."

Cassie's muscles ached as she rushed over to a bench and laid down on it, her gorgeous bubble butt sticking up into the air, totally defenseless.

Mr Kim chuckled. "Not for you, Miss Bergh. You're trying to please me, remember?"

Cassie let out a squeak as she jolted out of the way. Her sweat still clinging to the bench as Mr Kim laid down on it and... sniffed.

Not really knowing where to start with such a big body, Cassie abruptly started rubbing above his belt and worked her way up his spine. He groaned about halfway up so she dug in with her elbows and accidentally grazed his back with her tits.

"Good~ slut."

"Mhm," mumbled Cassie.

She tried to ignore her own pleasure and disgust as she pulled up his shirt and pretended not to notice her tits continuing to drag across his back. She pushed down again under his shoulder blades and got another moan. Is this how those happy-ending masseuses felt? Mr. Kim's back was so much bigger than hers, despite being a swimmer, despite how little he apparently worked out. Men were just larger.

Cassie reached for his belt.

He grabbed her wrist. "What are you doing?"

"I know this is what you want," Cassie said, defensively.

"No, it's what you want."

Literally not! It's not me who— well it's not my fault this — He knows he wants this!

"Then I won't." She crossed her arms.

Mr. Kim turned over and looked into Cassie's eyes. "It would please me, if you want to do it."

Cassie's chest rose and fell as thoughts drifted in and out of place.

"Let me?"

"I will. However, you need to say it: I. Want. Your. Cock. Mr. Kim."

"I want your cock, Mr. Kim," Cassie motor-mouthed.

"Slower." Mr Kim grinned.

"I want your cock, Mr. Kim."

"Good girl." Mr. Kim smiled and slid off his pants. "Was that so hard?"

Instead of answering, Cassie took his cock into her mouth as deep as she could. Fuck this guy. I'm not a highschooler. His cock tasted so good though, and honestly, she needed to spend more time with a cock in her mouth if her new style was going to stick.

His weird petting was ignored while she got her mouth down his cock and coated it in her spit. The veins were so strong and masculine. Each groan she got from him was like an inner-ear massage begging her to do more — she wanted so much more.

"Don't touch yourself. This is a punishment, young lady."

Cassie pulled her fingers out of herself and rested them on his knees with a sharp exhale. Thinking was overrated at this point. She decided to just listen to him and the music until this was over and try to enjoy herself.

"Use your boobs."

Letting her drool spill out into her sweaty cleavage, she started rubbing his cock with her breasts. At first it was awkward, she'd never given a tit-job before. But in a few seconds the motion became normal and his groans were ecstasy. A finger to her chin directed Cassie's gaze into his eyes as he climbed toward his orgasm.

"Good toy."

Fuck.

"When it starts to come out I want you swallowing every drop."

Cassie lost herself in cock. Covered in her spit, she pushed her boobs together and ran them up and down his shaft. Pinching her own nipples helped stem the throbbing need to be fucked until he took her head in his hands and pushed the tip into her mouth.

It felt so good to be used. Finally a hard cock in her mouth. Finally a rough hand on her head. Little whimpers just spilled out.

Mr. Kim slapped her lightly and then pushed her down onto his cock — cum poured out. She barely resisted, just two fiery eyes looking up at him as he emptied his load. He'd been saving it up all week to shoot into this blonde's stomach. All week.

"Every drop..." he groaned.

Gulp... Gulp...

The bastard wasn't done, though. Viagra was a miracle drug, and watching as his hypnotized toy played with her pussy on the floor of a gym, covered in spit and cum, lit a fire in him. The look of dismay on her face as he picked her up off the floor by her hair and spread her over the bench only made him hornier.

Cassie perked up her ass and pulled her panties to the side. She needed this just as much as he wanted it.

Mr. Kim didn't hesitate.

"Fuck," Cassie breathed.

As he bottomed out, she could feel how his cock made her bulge. In and out, he was using her as a cocksleeve now, just as she predicted. Just a cocksleeve until she could figure out how to blackmail him back...

"Back up into me," he said

What?

Mr. Kim slapped her ass.

"Fuck yourself on my dick or I'm sending you home without any clothes, Miss Bergh."

Cassie slid herself over his cock in doggystyle, shaking from exhaustion and pleasure.

"Exactly like that. Keep pace with the music."

Cassie focused entirely on keeping his cock pumping in and out of herself. She would get him back eventually, but now... now she would let him win. He spanked her again and her toes curled as she started to cum.

Mr Kim took both his hands then and put them around her tender throat, pumping his cock in a slow deliberate manner.

"Tell me you want my cum, Miss Bergh."

"Yes!"

"Tell me or I stop."

"Please cum," Cassie whimpered.

"Be studious. Where do you want the cum?"

"Cum in me, Mr. Kim!"

Holding her neck, he took her words as full consent to finish inside her. Pinching her bratty tits, slapping and squeezing the teen, torturing her deviant little body for his pleasure— Mr. Kim came deep and didn't pull out until she was completely imprinted by his cock. Everything was right in the world.

When he pulled, he was hit by a wave of hyper-sensitivity and exhaustion.

Shit, I may have overdone it.

Cassie slipped down off the bench onto the ground, breasts rising and falling, pussy leaking his cum out onto the floor. The sense of pride was overwhelming. This was what he should have been doing in his youth. Not chasing education and placating his parents; he should have been fucking little college sluts.
