【Ammolite】Big Brother, Teach Me – Secret Health Practice with My Sister-in-Law [Android Version].

■□■Story
It is yesterday that I am reminded.

[Use your brother’s body as a teaching tool and teach him health and physical education!]

My sister, Yuri, attends a prestigious nursing school.
I thought she was well on her way to becoming a nurse, but apparently [her mind goes blank when it comes to the male body].

But what about the idea of using my body as a teaching tool for practice?
Is it okay for siblings to do that?
No matter how much we are not related by blood.

Before I could think of anything else, my sister came home.

My sister seems to have forgotten about last night’s promise.
I was secretly puffing out my chest.
I’m not going to be able to teach health and fitness after all.
Just when I was feeling relieved, I went to …….

“Oh, um, …… big brother. Tonight …… health and physical education class, please ……

I nodded my head as if I were being carried away by the words.
I wonder what’s going to happen tonight.
The thought of it made my heart beat faster.

“Kenichi’s sister-in-law.
From the beginning of her parents’ remarriage, she has had a faint feeling for Kenichi.
As they live together under the same roof, their faint feelings for each other grow stronger and stronger, and they become more and more curt to hide their feelings.

She is at an age where she is very curious about sex.

Kenichi Shiramine
Yuri’s brother-in-law.
He thinks Yuri is cute, even if she is curt.
