The reason why Arisa couldn’t swim was that she doesn’t float well, in other words, her posture in the water wasn’t good.

Ideally, she should float parallel to the surface of the water, with her head slightly down and her back at the top…

In the case of Arisa, her legs were sinking and her body was at an angle.

So Yuzuru began by correcting the way she floated.

The first one was the dolphin float.

Next, he had her do the jellyfish float… and finally, he had her float with her arms and legs extended.

“Wow, that’s amazing, Arisa! I can’t believe you can do this much in such a short time!”

“…Aren’t you exaggerating your praise a bit? I’ve only just managed to float.”

She could now float beautifully.

When Yuzuru exaggeratedly praised her for that, Arisa frowned at him.

It looked like she thought she was being ridiculed.

“Nothing like that… Even some people who can swim are not good at floating. Basics are important. I never thought you could learn it so fast.”

When Yuzuru said that, Arisa’s expression relaxed.

“R-really?”

And then she giggled happily.

Adorable… Yuzuru sincerely thought so.

Nevertheless, it is true that Arisa was cute, but it was also true that he praised her excessively.

…In the first place, Yuzuru had decided to praise Arisa regardless of her performance.

In other words, Yuzuru was sweet on Arisa.

“…what’s next?”

“Right. ..Now, I’m going to pull your hand while you’re floating, and you’re going to try to do some leg flapping.”

Practice went into the basics of how to swim… in earnest.

It was a training session for the leg flaps.

“…how was it?”

“Let’s see…”

The first fundamental problem for Arisa was her floatation, but she also had a major problem with her leg flaps.

Her knees were bent wide.

And she was splashing around on the surface of the water.

This was the reason why Arisa’s swimming looked like a “bug in a lake”.

When he told her this, she tilted her head.

“What’s it like to… not bend your knees?”

“Maybe you should sit down and practice.” 

Yuzuru sat Arisa down by the pool and instructed her to try moving her legs.

The movement was… a little awkward.

“…Are you sure not bending your knees is the right thing to do?”

Arisa frowned again.

Apparently, she had a habit of getting grumpy when she couldn’t do something.

It was a bit of a new discovery for Yuzuru.

“It doesn’t mean you really shouldn’t bend your legs like a stick. A little is fine.”

“How much is a little?”

“…Can I hold your leg?”

Arisa gave a small nod.

Yuzuru stood in front of Arisa and grabbed her beautiful legs with his hands.

(…It’s beautiful after all.)

She had long, slender legs and white skin.

From the toes to the base of the foot, the form was very beautiful.

(…and risqué)

Her swimsuit was a high-cut type, so her legs were exposed to a slightly sensitive level.

He felt bad about it, but Yuzuru was also a boy, so he couldn’t help but look at it.

“Um, Yuzuru-san… What are you looking at…?”

“No, sorry. I was just admiring you.”

“…do you think you’ll always be forgiven if you say that?”

Arisa said with a pouty face.

Her cheeks were slightly flushed.

…She didn’t seem to be that angry.

“Can you please forgive me?”

“Geez… Only because you were just looking, okay?” 

Arisa had an expression that said, ‘Can’t be helped ‘.

She didn’t seem to mind being seen by Yuzuru.

Now, putting all that aside.

Yuzuru was a little nervous, but he showed Arisa how to move her legs with his hands.

“Don’t bend your knees, but rather move them like this, in small increments. I don’t want you to bend your knees.”

“That doesn’t help you get very far, does it?”

“That’s okay because the foot flutter is more of a postural aid. Besides, you’re only kicking the water with your toes, so there’s no point in moving them too far.”

“Heh…”

Taking Yuzuru’s advice, she moved her feet by herself this time.

It was much better than the first time.

“Now let’s try it while holding on.”

“Yes.”

This time, he had her do the flap while holding onto the poolside.

At first, Yuzuru held onto Arisa’s legs and assisted her.

“Don’t take them out of the water, but keep them like this….”

“It’s okay to bend your knees a little, right?”

“Yeah. As long as you can kick the water with just your toes.”

Arisa followed Yuzuru’s advice and moved her feet.

She had good motor skills, and once she learned the tricks, her progress was rapid.

(…I’m having a little trouble keeping my eyes on her.)

Yuzuru’s vision showed a white back and rather large buttocks.

Her hips were swaying in time with the movement of her feet.

Yuzuru’s fiancé was a person of great proportions, so even just acting normal was sexy in itself.

“How was it, Yuzuru-san?”

“Yeah, I think it’s good. As expected of Arisa. You are improving so fast, it’s worth teaching you.”

“Ehehe… is that so?”

Arisa seemed to be in a good mood.

Turning his eyes away from his lovely fiancée, Yuzuru tried to keep his composure.

AN: I don’t know if she can swim with this method of teaching. Because even though I can swim, I’ve never given a lecture on swimming to someone who can’t swim. Nor do I understand why someone who can’t swim, can’t swim in the first place.

Well, I think the important thing is not whether the teaching method is right or wrong, but whether Arisa is cute or not in the process!
