Erotic Exercise My Older Sister

My older sister was waiting in the training room, having changed into exercise clothes.

Bra top and short leggings. This is what my older sister often wears when working out at home.

I always think about this, but isn't this kind of sportswear more sexy than just underwear?

It fits tightly to the body from top to bottom, and it is small. My sister's body was exposed as it was.

"Sister. I don't think this how we should do?"

"Hold on tight. Don't move. Strengthen your back."

"Ah okay."

My sister put her arms around my neck and wrapped her legs around my waist from the front.

It clung to me like a cicada clinging to a tree.

Naturally, my sister's pelvis pressed against my dick.

My cock, which had already not lost its erection, became even more excited.

It definitely takes a lot of effort on my body, but is it a proper exercise?

"Don't imagine anything strange. Because all I do is exercise."

"No, still."

Although my sister spoke calmly, her face was actually slightly red.

My sister must also be able to feel that I am having an erection.

My sister unwrapped her arms from around my neck.

Then, the center of gravity shifted to my sister's upper body, and her body sank backward.

Naturally, a load came to my waist where my older sister was hanging on.

This was not the time to have strange imaginations.

If I had let my guard down, I might have broken my back.

I strengthened my back to support my sister.

And my sister started doing sit-ups in that state.

"Rye, support my hips with your hands."

"Oh, yes."

With my sister's permission, I grabbed her buttocks with both hands.

My sister's butt is not just soft. Although she looked feminine on the outside, she was well-muscled on the inside.

Especially now that she was exercising, I could clearly feel those muscles moving.

It may vary from person to person, but I like my sister's body like this.

Because it's not a body that can be built with ordinary effort. It could be said to be the culmination of my sister's efforts.

"Rye, Don't think anything strange."

"Oh, I didn't."

Actually, I did a little bit, but it would be natural if she did this kind of thing.

Every time my sister gets up, she rubs my dick with her butt.

And every time she raises her body, her face gets close enough to kiss me.

My sister's face also turned bright red.

I don't know if it's because of the shyness or the amount of exercise.

"It's okay. Please drop me off."

My sister completed twenty sit-ups.

She was sweating much more than usual.

"Whoa… So what's next…" My sister was out of breath while searching for something on her smartphone.

"Sister. Can't you just exercise normally?"

My older sister glares at me with sharp eyes.

And then she held out her phone screen towards me.

"Rye. We do this next time."

"Ah!?"

A video was shown on the phone screen of a man and a woman sitting across from each other, splitting their legs apart in a straight way, and then they got closer to each other, touching each other's legs.

The man and woman in the video had their legs completely straight up on the side, and their upper and lower bodies were in close contact.

"Hey, sister. I'm not as flexible as you?"

"You can be more flexible starting today."

My sister is the type of person who, once she decides to do something, carries it out without even asking questions.

The other person's opinion wasn't important there.

"Please be gentle."

A mischievous smile appeared on the corner of my sister's lips.

All I could think about was anxiety.

"Come on. Your sister will hug you."

We sat across from each other, stretched our legs, and moved together. We touched our legs together and put our arms around each other's necks.

As I got closer to my sister's body, I could smell the sweet smell of sweat.

Could this be a pheromone?

If we hug each other's upper bodies and come in close contact, then our lower bodies will also come in close contact, and our legs will naturally be split apart.

My sister began to count, and my leg's muscle fibers started to hurt.

"One."

My sister had already started counting, and my legs started to tremble.

"Two!"

And my older sister hugged me.

It was a very childish strategy, but I was completely caught up in that childish strategy.

And my legs were literally split apart.

Suddenly, I grabbed my crotch and rolled around on the floor.
