First cry of a newborn baby is magnificent and lovely

“……Haa……haa……♪”

After the run was over, Sayaka left Minato and immediately retreated to her room.

She didn’t shower off her sweat or even change her clothes,….. but she didn’t lie on the bed…..she was just sitting still in her room.

“What……is this?”

It was a new sensation.

Something she had never had before,……Sayaka thought about what this was–her body was sticky with sweat and she felt uncomfortable, but what bothered her even more was this sensation.

“Why is my hand on my chest……?”

Naturally, her own hand touches her chest.

The big bulge that grew rapidly when she became a highschool student……and made her feel bad about attracting the attention of boys, Sayaka rubs it.

“Ah……♪”

The sweet stimulation flowing through her body at that moment made her feel……Sayaka knew for the first time that it was sexual pleasure.

She had never experienced anything like this before, or even heard of it from anyone.

She had never even thought of trying it, and she was a genuine, pure girl no matter how far she went.

“I can’t forget that scent,……that smell,……won’t leave me,…….♪”

It is the scent of Minato’s sweat.

He always thought he didn’t want to be thought of as dirty or smelly, but apparently not for these sisters.

Minato’s sweat drove Yume crazy, and in Sayaka’s case, it was the catalyst for her to gouge open a door that had been closed for so long

“Minato kun……Minato kun……ah this sweet stimulation……this is what it is♪”

She understands that she is committing a shameful act.

Still, more than that, Sayaka feels happy that she knows this feeling of comfort that occupies her heart, and that Minato is the person she imagines after this act.

“Minato kun…… all of them, all of them are my first…..!”

Sayaka kept her distance from boys because of her circumstances.

Because of this, there were no boys that she wanted to be friends with, let alone close ones,……but when Minato saved her a few days ago, she felt something special, and through the unlikely fate of becoming a family together, Minato became too much in Sayaka’s mind.

“……?!”

Sayaka’s body trembled at what came at that moment.

At this point, she finally realized that she’s a woman–she was no longer just a high school girl.

She is a woman old enough to know about sex.

“Oh man, exercise is good.”

I scrubbed my head while muttering something like that.

I asked Sayaka if she wanted to take a shower first, but she said it would be fine later and headed to her room, so I ended up getting the first bath…but today’s run was a pretty good time.

“….Haa～”

But still,…..it was a happy time in a way.　

Being able to run with a girl was a precious time, but more than that, Sayaka’s breasts were swaying while running…every time I see something like that, it makes me feel like I’m a man.

“Okay, time to get up soon.”

I left the bath without soaking in the tub.

I went straight to Sayaka’s room and after knocking on her door, I told her that the bath was ready and went back to my room.

Before going to the bath, Sayaka looked into my room.

“……Sayaka?”

“Minato kun. Thank you very much for today–I really enjoyed it.”

Smiling, Sayaka went straight to the bath.

If Sayaka thinks so, then I’m happy too……it looks like it might be a good idea to invite her over for a run next time.

“……What is it?”

Suddenly, I smelled something familiar.

The place I approached as I sniffed was the location of the door where Sayaka was just a moment ago,……and what I smelled from there was that smell–the one I smelled from Yume’s room when she was in the restroom.

“……Do they have the same smell because they are sisters?”

I tilted my head and wondered what this scent was.

There’s no doubt that it smells good, but if I keep smelling it, it’s a smell that will make your brain tingle and go numb.

“……That’s something that makes me nervous.”

My heart beats strongly.

This feeling is the same as that time….I’m aware that this is excitement, so when I understand that, I’m the worst when I get excited by the smell of girls, and on the contrary, I calm down.

“……Getting excited by a girl’s smell is the worst……as expected, I have to be careful not to let them guess it by my facial expression.”

I have to make sure that they don’t find out….okay ! I shouldn’t be fooled by this smell anymore !

Later, Yume came home after club activities were over.

When she found out that Sayaka and I had gone running together at lunch, she invited me to go with her this time.

“I-I get it !”

“Really? I mean, let’s all go together, including Onee chan.”

So the three of us decided to go running together this time.

It was during this conversation that my dad and Mihoko san looked at me smiling that we had become really close.

It was a bombshell statement, or rather, the story popped out.

“About next week. We’re thinking of going on a honeymoon.”

“It was a little sudden, but our plans fit together. Of course, if it makes you guys uncomfortable, we’ll cancel.”

That’s too sudden !

But….that’s a little too much, isn’t it?　Because when my dad and Mihoko san are gone, there’s only going to be me and the girls left…..

Isn’t that bad? Right……?
