フィットしちゃお！ ～年上女性と 汗だくレッスン初体験～

I am a college student aiming for professional instructor.
By the time the school begins its summer vacation,
I was asked to be a part-time trainer in the gym.

The contact person is Mao, a cousin who runs a fitness gym.
It has been several years since we last contacted each other.
So, I was supposed to start my part time job by living in Mao-chan's apartment.
As naturally swept that away, I became the exclusive trainer for female members.
Really!?
Because of the trauma of the past, I do not get along with women,
My older sister cousin, Mao seems to have prepared that solution so that I can overcome it...

Some women have a very weak-willed, others are rebellious women.
Can I respond to their expectation to become an ideal figure?
Although I do not get along well with women yet, can I overcome myself!!??
