Dominating MIL

Since my mother-in-law said she wanted to focus more on her lower body than her upper body, I guided her toward the equipment suited for leg and glute exercises.

"Lower body workouts are better for keeping things nice and firm, you know♥"

"I suppose you're right…"

Her words and tone hinted at her real intentions. It was becoming clear that she was starting to flirt more openly, gradually turning up the charm.

She wasn't wearing standard workout gear. Instead, her outfit was made of a thin, sweat-reactive material that became more transparent as she exercised. After just a short run, her clothes clung to her skin, and the outline of her breasts and curves became clearly visible through the damp fabric.

It was a sight that made my dick hard against my will. My mother-in-law noticed my slight erection and gave me a lewd smile as she headed toward the exercise equipment.

She started with the leg curl machine, which targets the glutes and the backs of the thighs. I adjusted the weight to a lighter setting for her, then she positioned herself face down on the bench.

"I'm going to start now, so watch carefully♥"

In that position, her hips stood out even more, immediately catching my eyes. With the sweat-soaked, see-through fabric clinging to her, it looked almost as if she wasn't wearing anything at all.

'Why does it feel even more provocative when it's just slightly see-through like this?'

I've seen so many naked bodies that it's hard to count. I could tell who's who just by looking at the ass of the women I've trained.

Still, seeing my mother-in-law's ass in this way, both covered and uncovered, made them look even more lewd.

The room was not just for sex but also for exercise, and the high level of exposure made me heat up even more.

'Since this place is practically a full gym, it makes everything feel even more intense.'

It was like the thrill people get from doing something risky in places like movie theaters or karaoke rooms. Being alone together in a gym, secretly crossing the line, made the situation even more exciting.

"Could you touch me… and check if I'm doing it right?♥"

"Okay."

Squeeze…

"Hnnng♥"

At this point, there was no reason for me to hesitate. I placed my hands on her hips and began checking her form, making sure she was doing the exercise correctly.

"Aahh♥… Haa♥… Haa♥…"

Each time she curled her legs, her glutes tightened slightly, showing she was engaging the right muscles. But since that area still had more fat than muscle, it remained soft and yielding even when tensed.

"Haaa♥… My upper body keeps lifting. Could you press down on me from above, Trainer?♥"

"…Alright."

Clearly, just touching her wasn't enough for her anymore. She gave a small, deliberate wiggle of her ass, clearly trying to tempt me further. I sat down gently on her hips, placing my hands on her back and the nape of her neck to hold her down.

Press…

"Hnnnng♥"

There was no real reason to press down like that for the exercise. But she seemed to enjoy the pressure and the control it implied, so I did it deliberately. Judging by her moan, it was exactly what she wanted.

It was a position that looked like I was about to fuck her, but we were clearly in the middle of exercising.

"Haa♥...Haa♥…..Ugh♥…Aahh♥"

'She's doing it on purpose with her ass…'

She was exercising, but at the same time, she was moving her ass to seduce me and stimulate my dick.

She was a beginner, so she was exercising lightly, but she was a master at seducing men. Her ass was constantly stimulating my dick between her ass cheeks.

Thanks to that, my dick, which I was barely holding back, stood up on its own and became completely hard.

'Hold it in... hold it in.'

I was trying to relieve the tension of the interview through exercise, but my mother-in-law's seduction made it difficult.

"Phew... Okay, let's stop here for this one."

"Okay~♥"

My mother-in-law still seemed relaxed, but I couldn't hold back anymore and stood up. Seeing my erect dick, which looked like it was about to burst through my pants, she gave me a lewd smile.

"Then let's move on to the next one."

"Yes, Trainer♥"

Pretending not to notice her teasing tone, I guided her to the next machine—the hip adduction machine.

It targets the inner thigh muscles by having the user press their legs together from a wide, open position.

"Hehehe♥ Sitting like this… it kind of feels like I'm waiting to be devoured♥"

She smiled playfully while sitting with her legs spread on the machine. Her comment was meant to be a joke, but after hearing it, I couldn't help but see it exactly the same way.

Because her leggings were see-through, I could see her pussy. From sweat and other fluids, her pussy was even more transparent, clearly showing the split of her cunt and seducing me.

"Gulp..."

I came here to exercise, but my mother-in-law's constant seduction made it difficult to resist. I stood behind her, checking her posture, and I got excited.

"Just squeeze your legs together."

"Haa♥ Yes, Trainer♥"

My mother-in-law turned her head slightly to the side and looked at my erect dick through my pants. She gave a blissful smile. She looked impatient, as if she wanted me to pounce on her.

"Hnnn♥….Haa♥….Haa♥….Aahhh♥."

As she started exercising and squeezed her legs together, she moaned slightly, as if it were difficult. However, her gaze remained fixed on my dick.

"Hehehe♥ You seem to be having a hard time too, Trainer♥."

Slide… Slide...

"Ugh…"

I pretended not to notice my mother-in-law's actions and let her be. She was rubbing her face against my pants while seducing me.

Her behavior, reminiscent of an affectionate bitch, made me even more excited.

'It really feels like I'm a trainer being seduced by a client.'

With her constantly calling me "Trainer" and following my instructions, it felt like I had stepped into the role of her personal trainer.

At the same time, I was stuck in a situation where I had to act like a professional—ignoring the clear signs that my "client" was actively trying to seduce me—while still teaching her how to exercise properly.

"Trainer♥"

My mother-in-law gave me a lewd, lustful smile and stuck out her tongue slightly.

"Lick…Lick…♥"

She began licking my dick through my pants as she was seducing me. My patience reached its limit.

"How can you seduce me like this when I'm trying to teach you how to exercise?"

Slap!!

"Aahhhh!?!?♥♥"

Unable to resist any longer, I spanked my mother-in-law's chest with the flat of my palm—more like a punishment than a touch. She threw her head back, letting out a moan filled with pleasure.

Seeing the satisfied expression on her face, as if everything was going exactly the way she had hoped, I finally lost my composure too.

"I'm trying to clear my head with a workout! And you're just getting in the way!"

Squeeze…Slap!!

"Ooooh♥ I-I'm sorry♥♥"

I gripped her chest firmly, squeezing hard enough to change its shape. Though she tilted her head back in apparent submission, moaning with each breath, her expression betrayed her true feelings—she was smiling, clearly enjoying every second of it.

She had tempted me on purpose, wanting this reaction. Being handled roughly was exactly what she desired.

"Aahhh♥… Aahhh♥…"

Her legs had gone weak, and she could no longer bring them together. They remained spread open, completely relaxed.

"And you're all wet here!"

Squish…

"If you touch me now, ooooooh♥"

I stood in front of her and grabbed her pussy. As expected, it wasn't just sweat; it was wet with her pussy juice. It was so wet that my fingers easily penetrated it.

Squish… Squish… Squish… Squish…

"Ooooooot!?♥ Aahhhh?!♥"

The elastic leggings didn't tear. I put my fingers inside her pussy and stirred it around.

"Aahhhh♥ Ooooooot♥"

Thanks to the hip adduction machine, my mother-in-law was unable to close her legs. She was humiliated, her body trembling with pleasure and her pussy leaking juice everywhere.

"I am cumming♥♥"

Pshoooooooo...….

She cummed while spraying pussy juice everywhere. Her leggings couldn't stop her squirting pussy juices.

"I, I like being punished during exercise♥"

My mother-in-law was humiliated and unable to properly resist. She finally gave a satisfied smile.

"I'm not satisfied at all yet."

Slide…Slap!!

"Aaaah♥ Your di… Aahh!?♥"

I took off my pants and pulled out my dick. Then, I grabbed my mother-in-law's head and forcefully shoved it into her throat.

"Lick!♥ Slurp♥ Lick♥ Hoooop♥ Lick♥ Slurp♥"

I forced it into her throat, but she seemed happy and began sucking my dick. I quickly felt a rush of pleasure and cummed into her mouth. She sucked my dick as if it were delicious.

I was treating her like an onahole, just to relieve my sexual desire.

Brrt brrt brrt brrt

"Aahhh!?♥♥"

My mother-in-law didn't panic when she saw the large amount of cum. She started drinking it. She skillfully opened her throat and sucked it in.

"Sluuuuurp♥"

She sucked my dick as if she wouldn't miss a drop even if her cheeks were sinking in.

"Aahhh!?♥ Trainer♥"

I tore her leggings at that lewd seduction and lifted her up, heading to the place where we had stretched earlier.

In the mirror, I put her in a doggy-style position with her legs spread open, making her unable to escape. My mother-in-law had a deep smile on her face.

"You can't escape this, ever."

"I'm going to be fucked by my master♥♥"

My mother-in-law looked in the mirror while smiling with anticipation and excitement.

Squish… Salp!!

"Hiiieeeeeeet♥♥"

I put my dick inside her, and her pussy squeezed tightly around it. Her pussy was waiting for this moment and leaked pussy juice everywhere.

"Then I'm going to exercise, too. Squeeze your pussy tight, you sow!!"

"Y-yes, Master♥♥"

Somehow, I ended up using my mother-in-law as an exercise machine for onaholes.

Thump!!! Thump!!! Thump!!! Thump!!!

Slap!! Slap!! Slap!! Slap!!

Slap!! Slap!! Slap!! Slap!!

"Aahhhh!?♥♥"

Pusssss...

She tilted her head back as she was overcome by intense pleasure. But...

Squish! Squish! Squish! Squish! Squish! Squish!

Slap!! Slap!! Slap!! Slap!!

Slap!! Slap!! Slap!! Slap!!

I didn't care about her condition and just pounded my dick inside her horny pussy.

"Oink♥ Oink♥ Oink♥ Oink♥"

Like a sow, my mother-in-law was moaning vulgarly and was already half out of her mind with pleasure, but her pussy was still squeezing tightly.

"From now on, I'm going to use you as an onahole exercise machine, so be prepared!"

"Oink♥ Oink♥ Yesss♥ Oink♥♥"

Pusssss...

Brrt brrt brrt brrt

I ejaculated inside my mother-in-law's tight pussy, filling it with my thick cum.

"Haa… haa… phew, then I'll keep going."

"Oink♥… Oink♥"

My mother-in-law was making silly sow noises as if she had lost her mind when I moved my dick inside her pussy again.

I was getting a better workout than I expected, so I forgot about the tension of the interview.
