Personal Trainer Part 5: Alex’s Ultimatum

She told herself she could still turn around. Drive away. Stop this madness. Her panties were already damp when she rang the bell.

Personal Trainer Part 4: Double Life, by Mia Sumner

She woke early, eyes open, instantly awake. A glance to the side confirmed that in ten minutes her alarm would go off. She needed to be in Alex’s apartment in ninety minutes, dressed appropriately. That instruction had been weighing on her all week. Sliding out of bed, careful not to disturb the still sleeping Richard, she put her bare feet on the carpeted floor and walked over to the closet, wondering what exactly Alex wanted her to wear.

“Come back to bed babe.” Richard mumbled. Kathy glanced over her shoulder, but he hadn’t opened his eyes.

“I have an early appointment, go back to sleep honey.” It wasn’t entirely a lie, but it twisted her stomach anyway. Richard turned over, mumbling something she couldn’t make out. Guilt twisted into sadness at his disinterest.

She dressed quickly, pulling on fitted athletic leggings, darker and slimmer than her usual gym gear and just a cropped fitted top over her sports bra. It felt revealing. So fitted, nothing hidden underneath. Her office clothes went into a bag that she slung into the passenger seat. She was out of the house in under thirty minutes.

As she parked, her stomach twisted and knotted again. She was early, there was still time to just turn around, to just drive away and stop this madness. But the memory of what had happened last time sat fresh in her mind. The heat of Alex’s thigh between her legs, the way her own hips had moved without permission. Her skin tingling, her panties already damp.

This was a bad idea. She knew it was a bad idea. This wasn’t who she was. It was wrong. It was exciting. The thoughts kept going round in her head even as she got out of the car and rang the bell.


Alex’s apartment was smaller and less opulent than the gym, but it had the same controlled, minimalist energy to it and the room Alex led her into was cramped with workout equipment and a large mirror.

“Does Richard know where you are Kathy?” Alex’s calm, direct question cut through Kathy’s nervous buzz.

“He knows I had an appointment.” She evaded, but Alex’s cool eyes followed her in the mirror, a knowing look on her face. She was standing right behind Kathy, both of them facing the long mirror. Her hands on Kathy’s stomach now, gentle movements that she could feel through the skin tight clothing.

“He doesn’t really know though does he?” Alex’s lips brushed against Kathy’s neck.

Kathy shook her head, chest tight, breathing suddenly hard.

“Good Girl.” Alex breathed. Kathy followed the movement of her hands intently, her body begging for the clothes to be removed. “Time to choose Kathy. I will expect obedience.”

Kathy bit her lip, holding her breath. Her mind raced, pulse throbbing in her wrist.

“Yes.” She whispered, the heat and damp in her panties overwhelming any fear.

Alex stepped back at those words, her hands moving to adjust Kathy’s posture. Her words now all business. Slow holds, form corrections, her eyes intently scanning as she had Kathy perform each exercise multiple times.

Kathy’s body buzzed with barely contained excitement. The strain of the movements themselves now erotically charged, her skin aching for the next touch of Alex’s hands. Eager to hear her praise when she got the exercise right. She watched herself in the mirror. Face flushed, body tense and obedient. Waiting for Alex’s next one word command. Hold. Lower. Look. Ask. Again.

That simple act of withholding words left Kathy desperate for more.

“You’re doing very well Kathy.” Alex finally gave her the praise she had been so eager to hear. “Such an obedient girl.” Kathy flushed with pride. “Did you think about me after last week’s session?”

The question caught Kathy off guard and she didn’t even have time to think up a lie. “Yes.”

“Good girl. Did you lie to your husband about that too? Did you fuck him thinking about me?”

Kathy shook her head, shame flooding her again as she remembered each of the furtive masturbation sessions this last week. All of them featuring Alex, none involving her husband. Alex chuckled, somehow intuiting the answer from just that small gesture.

“Would you like your reward Kathy?” Alex’s voice was rich with amusement. Kathy nodded, embarrassed by her eagerness. “Look in the mirror Kathy.” Alex’s voice hardened now, clear command. “Look at yourself and answer me properly.”

Kathy stared at the mirror, her red cheeks, hair messed up, the obvious desperation in her eyes. “Please.” She said, her voice weak and pathetic to her own ears, but Alex smiled in satisfaction.

“Pull your pants down. Panties too. Keep looking in the mirror.”

Kathy’s eyes went wide. Alex had never been this blatant before, about what was really going on. Trembling, she pulled them down, her panties soon around her ankles too. Alex stepped in close then, her body pressing against Kathy’s. Her fingers slipping between Kathy’s legs. Sliding in easily, the slickness of it making Kathy flush deeper.

Alex’s lips were on Kathy’s neck again as her fingers thrust in and out. Kathy stared into the mirror, breath coming hard now. So exposed, so vulnerable. Staring at herself, and Alex in the mirror. The moans she was making almost alien to her ears.

A third finger then a fourth slid between Kathy’s slick lips. She gasped as Alex stretched her, the movements less gentle now as though forcefully claiming what was hers. Kathy’s hands pressed against the glass of the mirror, her body a toy now to Alex’s whims. Heart thumping, breathing fast as Alex’s whole hand took her. Stretching her like never before. Forcing gasping squeals out of Kathy’s body.

Her teeth bit down on Kathy’s shoulder. Sharp, sweet, pain contrasting with the overwhelming pleasure. Kathy shuddered and moaned and came, as Alex bit down hard. Her pussy clenched hard on the fist inside her.

They stayed like that forever, or so it seemed. But eventually, Alex removed her hand, sending further waves of pleasure through Kathy. She stepped away, suddenly composed again.

“That will leave a mark. You’ll need to be a little careful around your husband.” Her voice was steady, calm, but Kathy detected a note of satisfaction. “Leave the panties. You won’t be wearing those anymore.”


Kathy arrived late to the office and straight to the restrooms to change and fix her hair. No panties. The simple instruction echoed in her head. Even as she sat in meetings, she was conscious that she had nothing under her skirt. Her calm, controlled voice masked the whirling thoughts in her brain. Every movement now a reminder to be careful and conceal her secret.

“You look… freshly fucked.” Melanie’s voice bubbled with teasing laughter. Kathy flinched, glancing at the door to her office to confirm it was shut. Melanie just laughed louder. “Well? Was James as good as he looks?”

“I… no… what… I haven’t!”

“Mmmhhhmm… I know you got fucked. About time someone gave you what Richard isn’t.” Melanie just smirked, clearly unconvinced. Kathy flushed redder and redder, remembering Alex’s fist between her legs.

“Stop that!” Kathy’s protests were cut off by her phone buzzing. It was Richard. She picked it up and scanned the text. A harmless request that she pick up some groceries on the way home tonight. When she looked up again, Melanie was watching her closely.

“Disappointed it’s not from your secret lover?” She teased. Kathy felt her cheeks grow hot. She adjusted the collar of her blouse self-consciously, suddenly very aware of Alex’s mark on her shoulder. The silence expanded.

Another buzz from her phone saved her. She glanced down hurriedly, assuming it would be more mundanity from Richard. It was Alex.

Show me you’re obeying.

She glanced at Melanie who was still watching her. “Uh, I need to go to the little girls room.” She was already standing as she made her excuses.

The bathroom stall familiar and yet now strangely unfamiliar to her, she sat down, spreading her legs wide. A quick glance at the door, just to make sure the stall was really locked, and then she lowered her phone between her legs. For one sane second she nearly stood up and walked out, the absurd risk of what she was doing cutting through the haze. Then she snapped the picture. Kathy didn’t give herself time to think, sending it to Alex immediately and then waiting, squirming, for the response. When it came, it was only one word.

Edge

Her hand was between her legs before she’d even finished reading. Fingers rubbing and circling, a moan escaping before she could bite it back.

Another text from Richard, she ignored it, fingers moving faster. Her mind flashed back to this morning. Alex pressed against her. Alex marking her. She bit her lip, trying to stay quiet, trying to control her breathing. Her two worlds crashing together as she masturbated frantically in the work restroom at Alex’s command. Another text.

No panties all day tomorrow.

Richard’s text sat unanswered as Kathy’s fingers moved faster, her whole body focused on Alex’s next message.

If I text, you will edge. Wherever you are.

A whimper escaped Kathy’s lips and she froze, until her ears confirmed there was no one else present. Then back to rubbing.

No cumming without my permission.

Kathy didn’t even think before responding with her free hand. “Yes Alex.”
