Mika Fujimori age:24,job:Personal trainer

"…Well, thank you for your help. I look forward to working with you, Mr. Nagai."

"Ah, likewise. Thanks."

That was last winter.

Anxious about the physical decline that comes with aging, I recently made up my mind to start going to a fitness gym. My main goal, of course, was to stay healthy, but on top of that, I was hoping I might meet some young women.

Feeling a bit bewildered on my very first visit, I managed to get through registration, changed in the locker room, and stood waiting for today's assigned trainer to come out.

"I’ll be taking care of you today. My name is Mika Fujimori. Pleased to meet your acquaintance."

The woman who appeared before me was practically a dream come true.

She was twenty-four years old. I was told she had joined this workplace right after graduating from university. She was exactly twenty-four years my junior—an age difference that clearly ruled her out as a romantic prospect.

And yet, in that very instant, I fell head over heels for her appearance.

Dressed in a black pantsuit, Mika had a glamorous figure, but her stylish, boyish attire gave her an appearance that could almost pass for a man's from a distance.

In front of me, she softly flicked the hem of her jacket, stepped forward, and smiled brightly.

"What would you like to start with?"

"Umm, well... let's start with stretching."

"Understood. Right this way, then."

Led by Mika, I headed toward a massage room inside the gym.

At first glance, it didn't look like a place for massages, but apparently that was where she planned to do the stretching. A yoga mat was spread out on the floor, and the room felt cleaner than I had expected.

"First, please lie on your back."

I laid down just as I was told.

Mika stood beside me, slowly scanning my body from above.

"Alright, let's start with leg stretches first."

With that, she lifted my right leg and straightened the knee.

"Okay, please hold this position for about ten minutes."

"Huh, ten whole minutes?"

"Yes. To stretch the muscles properly, at least ten minutes is necessary."

"I see..."

To be honest, keeping one leg raised for ten minutes was quite tough. Sweating, I endured the time.

"Alright, next is the left leg."

When time was up, she lowered my right leg, raised the left one, and stretched it the same way.

That made twenty minutes total.

"Mr. Nagai, if you feel any muscle soreness or anything, please don't hesitate to speak up."

"No, I'm alright."

"Is that so? In that case, let's move on to upper-body stretches."

"Okay."

She pulled me up into a sitting position and moved behind my back. Then, bringing her hands around front, she touched my chest.

"Um..."

"It's alright. I'm just stretching your chest muscles."

Sure enough, she was massaging my chest with her soft hands, but this was strictly part of the stretch routine.

"Hold this for ten minutes, too."

"Yeah..."

Every time her fingertips touched my nipples, a heat gradually built up in my groin.

"..."

Mika continued to stimulate my chest in silence.

That stretch of time felt hellishly long.

"Alright, next is your back."

Finally, she let go.

I remained in position, waiting for her next move.

"Okay then."

This time, she reached behind my back and began to slowly stroke it.

"Ngh..."

I accidentally let out a small groan.

"Is something wrong?"

"No, it's nothing."

"I see. Let's continue then."

Using both hands, she slowly kneaded my back from top to bottom. The sensation felt so much like getting a massage from a lover that I gradually grew aroused.

"Alright, ten minutes have passed."

Her hands finally lifted.

I let out a sigh of relief, but at the same time, I felt a lingering sense of insufficiency.

"Next, we'll do abdominal exercises."

"Abdominals?"

"Yes. Please lie on your back and bend your knees."

"Like this?"

I adjusted my posture as instructed.

"That's it. Now, I'll hold your legs, so please lift your upper body."

"Got it."

Mika grabbed both of my ankles and pulled them up toward her chest area.

"Alright, here we go. One, two, three..."

I raised my torso in time with her count, then lowered it back down. I repeated this ten times.

"Okay, rest for ten minutes, and then let's do ten more."

"Okay..."

Breathing heavily, I took a rest, then started the sit-ups again.

"Great. Next, lie on your side."

When the ten reps were finished, she instructed me to turn onto my side.

"In this position, move your legs up and down."

"Like this?"

"Yes. Let's begin."

I moved my legs as told.

Meanwhile, she gently massaged my abs with both hands.

"..."

The sensation felt so good that I reflexively closed my eyes.

"Mr. Nagai, we're all done."

"Ah, right..."

Snapping back to my senses, I sat up.

"That's the end of the stretching. How was it?"

"Yeah, it felt really great."

"I'm glad to hear that."

Mika smiled with satisfaction.

"Next is workout training. What would you like to do today?"

"Let's see... push-ups sound good."

"Understood. Let's do them over on that mat."

Prompted by her, I moved to the adjacent mat.

"First, try doing them on your knees."

"On my knees?"

"Yes. Start on your knees, and once you get used to it, you can lift them up."

"Got it."

Following her instructions, I rested my knees on the floor and began doing push-ups.

"Once you do ten, take a break."

"Okay."

Following her directions, I continued doing push-ups, taking breaks in between.

"Alright, now try with your knees off the mat."

"Understood."

Standard push-ups this time.

"Once you do ten, take a break."

"Ugh... I can't..."

I ran out of strength at seven.

"You're doing fine. For your first time, this is plenty."

Mika offered encouraging words gently.

"Next, let's use dumbbells. How many kilograms would you prefer?"

"Let's see... five kilograms."

"Understood."

She grabbed two five-kilogram dumbbells from the rack and handed them to me.

"First, stand up, bend your arms, and curl them up."

"Like this?"

"Yes. Let's do ten reps like that."

I lifted the dumbbells just as she instructed.

"Alright, rest for ten minutes, and next, try doing them while seated."

"Seated?"

"Yes. Sit on the chair, bend your elbows, and lift the dumbbells."

"I see. This might actually be easier."

"That's right. Give it a try, then."

I sat in the chair and curled the dumbbells.

"Great, once you do ten reps, take a break."

"Ahh..."

And so, I carried on with my workout.

After about an hour had passed, she called the time.

"Alright, that's all for today. Great job."

"Thanks for your hard work. Thank you too, Mika-chan."

"Not at all! I look forward to working with you next time as well."

With that, she bowed her head and walked away.

Left alone, I headed to the locker room and took a shower.

Once I got back home, I immediately crashed onto my bed.

"..."

My body was exhausted, but my mind was entirely consumed by thoughts of her.

"Mika-chan..."

Whispering her name, I gave myself over to self-gratification.

That was how our relationship began.

A few weeks later, I was visiting the gym as usual.

"What would you like to do today?"

"Well... I'd like to run on the treadmill."

"Understood. Let's head over, then."

I walked over to the treadmill alongside Mika.

"How about the speed?"

"Let's start with a walk."

"Understood."

She switched on the machine and adjusted the speed.

"Alright, please go ahead."

"Okay."

I began walking at a slow pace.

Mika stood beside me, keeping track of the time while watching over me.

"Ten minutes have passed. Next, a brisk walk."

"Got it."

I raised the speed and switched to a fast walk.

"Alright, ten minutes have passed. Next is jogging."

"Alright."

Jogging this time.

"Alright, ten minutes have passed. Next is running."

"Okay!"

I started running at full speed.

"Alright, ten minutes have passed. Great work!"

"Ah, thanks."

Stepping off the machine, I wiped away my sweat with a towel.

"What would you like to do next?"

"Hmm... abdominal exercises sound good."

"Understood. Over to the mat, then."

Once again, I performed abdominal exercises on the mat.

"Great, rest after ten reps."

"Y-yeah..."

I did the sit-ups with everything I had.

When I finished ten, I caught my breath.

"Next are leg raises."

"Leg raises?"

"Yes. Lie on your back and raise both legs straight up."

"Like this?"

"Yes. Let's do ten reps of those."

"Got it."

Following her instructions, I raised my legs.

"Alright, rest for ten minutes, and next we'll do side bends."

"Side bends?"

"Yes. While standing, bend your torso to the side."

"I see."

I stood up and bent my body to the right, then to the left.

"Great, take a break after ten reps."

"Ahh..."

In this manner, I pushed through my workout.

An hour later, it was time to wrap up.

"Great work today as well."

"Yeah, thanks. Thank you too, Mika-chan."

"No, the pleasure was all mine. I look forward to next time."

"Yeah."

She left with a smile.

I showered in the locker room and went home.

After dinner, while I was sitting around thinking about Mika, a message popped up on my smartphone.

“Good evening, Mr. Nagai. This is Fujimori. Great job today! See you next week.”

“Thanks! See you next week.” I replied.

A response came back immediately.

“To tell you the truth, I’ve been thinking about you a lot... If you’re open to it, would you like to grab dinner together sometime?”

"What?"

My eyes went wide at the unexpected message.

To think Mika-chan would be the one asking me out...

I wrestled with the thought for a while, but ultimately decided to accept her invitation.

“Sure thing. Pick a place and book a spot for next Friday.”

“Yes! Understood. I’m really looking forward to it then!”

With that, her messages ended.

"..."

Clutching my smartphone, my heart raced with excitement.

"I can't wait for next week..." I muttered, crawling into bed.

A week later, the long-awaited day finally arrived.

"Mr. Nagai, sorry to keep you waiting!"

"No, it's fine. More importantly, Mika-chan, you look breathtaking today."

"Thank you so much!"

Mika wore an elegant dress, and her makeup was done to perfection.

"Shall we go then?"

"Yeah."

We headed to the restaurant she had reserved.

"This is a nice place."

"Yes, I come here quite often."

"Is that so?"

We took our seats and placed our orders from the menu.

"Do you always eat at places like this, Mika-chan?"

"No, just occasionally. I mostly come here with friends."

"I see. Do you have a boyfriend or anyone like that?"

"No, I don't right now."

"I see. So I'm the first, huh?"

"Yes. But I was really looking forward to having dinner with you, Mr. Nagai."

"I-is that so? I was really looking forward to it too."

I answered, feeling embarrassed.

"You really look so young, though, Mr. Nagai. I would never guess you're fifty."

"Haha, thanks. But in reality, I'm just an old man now."

"That's not true at all. I actually prefer older gentlemen like you."

"..."

My heart skipped a beat at her words.

"You really are such a sweet girl, Mika-chan..."

"Aw, look at you getting bashful! That's cute."

She giggled quietly.

"Still... why did you invite me out?"

"Um... well, to be honest, I was really curious about you..."

"Curious?"

"Yes. I thought you were handsome right from the start."

"I-is that so...?"

"Plus, I love the expression on your face when you're training."

"My face?"

"Yes. You look so earnest and cool."

"Hearing you say that makes me really happy."

I blushed even more.

"So... if it's alright with you, I was wondering if you would go out with me...?"

"..."

I was struck speechless by her direct confession.

"Of course, if that's impossible for you, feel free to decline..."

"N-no, not at all! I like you too, Mika-chan."

"Really?!"

"Yeah. So let's date."

"Yay! Thank you, Mr. Nagai!"

Mika threw herself at me in joy.

"W-woah, calm down a bit!"

"I'm sorry, I was just so happy..."

She buried her face into my chest, her body trembling slightly.

"Well, it's fine. So from now on, we're officially lovers."

"Yes! I'm in your hands, Takumi-san."

"Yeah. Likewise."

And just like that, we officially started dating.

Several months passed after that.

Mika and I were smoothly deepening our relationship.

Naturally, I continued my workout sessions at the gym, but outside of that, we went on dates frequently.

"Takumi-san, where shall we go today?"

"Hmm... how about going to see a movie?"

"Sounds great! What would you like to watch?"

"What do you want to see, Mika-chan?"

"Anything is fine with me. Let's watch whatever you like, Takumi-san."

"Alright then. How about that action movie?"

"Understood!"

We headed over to a nearby multiplex.

The movie was incredibly fun, and we both had a blast.

"That was so much fun!"

"Yeah, I'm glad."

"Shall we go shopping next?"

"Sounds good. What should we look for?"

"I don't really need anything in particular, but..."

"Oh? Then how about looking at some clothes for you?"

"Sure! And I'll help pick out something that looks great on you too, Takumi-san."

"I'll rely on your taste."

With that, we headed off to a department store.

"Takumi-san, how about this one?"

"Hmm, looks good. Maybe I'll buy it."

"Yes, it really suits you!"

"You think so? Thanks."

I tried on the shirt she selected in the fitting room and checked myself out in front of the mirror.

"Yeah, it really does fit well."

"Right? You look so handsome!"

Mika nodded in agreement, looking satisfied.

"Alright, I'll buy this one."

"Great!"

After paying at the register, we made our way to the next shop.

"Mika-chan, isn't there anything you want to buy?"

"Not particularly... but if you're offering to buy me something, Takumi-san, there is one thing I want."

"What would you like?"

"Um... lingerie."

"Lingerie?!"

"Yes. The ones I'm using now are getting old, so I want to replace them."

"I see. Then I'll buy them for you."

"Thank you so much!"

Mika smiled happily.

"Alright, let's head to a lingerie shop."

"Okay!"

We entered a specialized lingerie boutique.

"I wonder what's good..."

"Takumi-san, how about this one?"

"Hmm? This one? Looks nice, doesn't it?"

"Thank you! I'll take this one then."

She purchased a matching set of a lace bra and panties.

"Next, I'll buy something for you, Takumi-san!"

"Huh? For me?"

"Yes! Is that okay?"

"Well, sure..."

"Come over this way, then!"

Led by her, we moved over to the men's underwear section.

"What kind do you prefer, Takumi-san?"

"Hmm... nothing in particular, really."

"Is that so? Then how about something like this?"

The item she picked up was a pair of silk trunks.

"Yeah, that looks nice."

"Then I'll buy this one for you!"

"Ah, thank you."

I said, feeling a little embarrassed.

"Matching underwear!"

"Guess so."

"Let's keep using these from now on."

"Yeah, sure."

Mika looked like she was having the time of her life.

Having bought our underwear, we started on our way home.

"Today was so much fun!"

"Yeah, I enjoyed myself too."

"See you tomorrow at the gym, then!"

"Yeah. See you tomorrow."

Parting ways with her, I hurried home alone.

The next day, when we met again at the gym, her vibe felt somewhat different from usual.

"Good morning, Takumi-san."

"Good morning. Looking forward to today as well."

"Yes! Let's get right into training."

"Alright."

We started off with stretching, as usual.

"Takumi-san, you seem a bit more tense than usual today."

"Really? Feels the same as always to me, though."

"Is that so? Well then, let's continue."

She touched my body as she proceeded with the stretching.

"..."

However, I was feeling far more aroused than usual.

"Takumi-san, is something wrong?"

"No, nothing..."

"Is that so? Next up is the actual training, then."

"Yeah."

Grabbing the dumbbells, I started doing push-ups.

"Take a break after ten reps."

"Y-yeah..."

Following her directions, I continued training with short breaks in between.

"Alright, that's it for today! Great job."

"Yeah, thanks."

"Well then, I'll be waiting in the locker room."

"Yeah."

Saying that, she walked away.

Left alone on the mat catching my breath, my smartphone chimed with a message.

“Takumi-san, I’m inside one of the private stalls in the locker room.”

"..."

Looking at that message, my heart rate spiked.

Could it be...?

Grabbing my belongings, I rushed over to the locker room.

Arriving in front of the private stall, I knocked on the door.

"Takumi-san, please come in."

"..."

Opening the door, I stepped inside.

There stood Mika, waiting for me in her underwear.

"Mika-chan..."

"Takumi-san, I've been waiting for you."

She hugged me.

"Why are you doing this..."

"Because, you know, I bought some underwear yesterday. I wanted you to see it as soon as possible..."

"I-I see..."

"And last night, I was fantasizing a lot..."

"Fantasizing?"

"Yes. I was thinking about having sex with you..."

"..."

Her bold statement excited me even more.

"Takumi-san, do you want me?"

"Yes, I do..."

"Then please, don't hold back, and give me lots of love."

She said that and then kissed me.

"Mmm..."

I was captivated by her soft lips.

"Takumi-san, put your tongue in..."

"Okay..."

I put my tongue into her mouth and intertwined it fiercely.

"Mmm, mmm..."

Mika was also engrossed, sucking on my tongue.

"Ah... mm..."

After a long kiss, she pulled away and caught her breath.

"Takumi, make me feel more..."

"Ah..."

I laid her down on the bed and climbed on top of her.

"Mm..."

Then I began to caress her breasts through her clothes.

"Ah, ah..."

"Mika, are you feeling it?"

"Yes, it feels really good..."

"I see. Well, then let me feel it more."

I removed her bra and began to caress her breasts directly.

"Ah, ah! Takumi, no, that spot is sensitive..."

"It's okay. I'll make you feel good."

"Ah, ah..."

When I pinched her nipples with my fingertips, she let out a moan.

"Mika-chan, your nipples are hard."

"Ahh, no, don't say that..."

"So cute. Feel it more."

I took her nipple into my mouth and began to lick it.

"Ahh, ahh, mmm..."

Mika was moaning, her body trembling.

"Takumi-san, I can't hold back anymore..."

"Is that so? Well, next is this."

I pulled down her panties, revealing her private parts.

"Wow... Mika-chan, you're so wet."

"No, don't look..."

"It's okay. You're so wet, you're trying to entice me, aren't you?"

"That's not it... Ahh..."

I traced her private parts with my finger.

"Ah, ahh..."

"It's so hot here."

"Mm, no, don't say that..."

"But it's true. Mika, you're so naughty."

"Ahh, stop it..."

She blushed, embarrassed.

"You don't have to be so embarrassed. I want to see all of Mika's naughty parts."

"Takumi..."

"And you're so wet, it's adorable."

"Ahh, please stop..."

"No. Feel it more."

I brought my face closer to her private parts and stuck out my tongue.

"Ahh! No, it's dirty..."

"It's not dirty. I want to taste Mika."

"No, stop, ahh..."

Ignoring her resistance, I licked her private parts.

"Mm, ahh, aahh..."

She gradually began to moan. "Mika-chan, it's amazing, so delicious."

"Ah, ah, stop, don't say that..."

"It's true. Can I lick it more?"

"Ah, that's enough... Please, lick it..."

"Ah, thank you."

I continued to lick her private parts meticulously.

"Ah, ah, ah..."

She continued to moan, writhing her body.

"Takumi-san, I'm about to come..."

"Really? Then go ahead and come."

"Ah, ah, no, I'm going to come..."

"It's okay. I'm watching."

"Ah, ahhh! I'm coming, I'm coming...!"

She arched her body like a bow and reached her climax.

"Haa, haa..."

She relaxed her body, breathing heavily.

"Mika-chan, did it feel good?"

"Yes... It felt really good..."

"I see. That's good then."

I gently stroked her head.

"But Takumi-san, you haven't yet, right?"

"Yeah. But it's okay."

"No, that's not right. I want Takumi-san's penis too."

"Mika-chan..."

"Hey, please put it in..."

She looked at me with her eyes looking up.

"Okay. I'll put it in."

I took off my pants and positioned myself against her private parts.

"Mika-chan, I'm putting it in."

"Yes... Please..."

I slowly moved my hips forward.

"Mmm, ahh..."

Her vagina was very warm and tight.

"Mika, wow, you're so tight."

"Ah, ahh, Takumi's penis is so thick..."

"Hold on. It'll all fit."

"Yes..."

I buried myself completely inside her, then stopped moving for a moment.

"Ah... It's all in."

"Ah... Wow, I'm so full inside..."

"Does it feel good?"

"Yes... It feels really good..."

"I see. Then I'll start moving."

"Yes... Please..."

I slowly began to move my hips.

"Ah, ahh, ahh..."

"Mika, it feels so good inside..."

"Ah, ahh, it feels good for me too..."

We devoured each other's bodies, making love.

"Takumi, do it harder..."

"Okay. Here I go."

I grabbed her hips and began to thrust violently.

"Ahh, ahh! Amazing, it feels so good...!"

"Mika-chan, you're so cute. Moan more..."

"Ah, ahh, ahh, mmm..."

She moaned in time with my movements.

"Mika-chan, are you going to cum?"

"Yes, I'm going to cum, I'm going to cum now...!"

"Let's cum together."

"Yes...! Ahhhh, I'm cumming, I'm cumminggg...!"

"Damn, I'm going to cum too...!"

I released my semen inside her.

"Ahh, ahhhh..."

She reached her climax at the same time.

"Haa... haa..."

We hugged each other, drenched in sweat.

"Thank you, Takumi-san."

"No, the pleasure was all mine. Mika-chan, that was amazing."

"It was amazing for me too."

She smiled contentedly.

"Let's do this a lot more from now on."

"Yes. I love you, Takumi."

"I love you too."

I hugged her tightly.

And so, our relationship deepened even further.
