fit! ~First experience of sweaty lessons with older women ~ (Related products of this title)

i am a professional student aiming to become an instructor.
One day, when I was about to enter the summer vacation, I had an invitation from a part-time job at a fitness gym.
The contact owner is Moo-chan, a cousin who runs a gym. It is the first time in a few years.I was supposed to start a part-time job by living in a boat and an apartment of my sister.
However, as it is washed away, it will be in charge of the exclusive of many women suddenly!?
Apparently worried about me who has become bad at women due to the trauma of the old days, my sister seems to have suggested a plan, but ......What gathered was a rebellious or very weak woman of intention.
Can I meet the expectations of the girls who want to be their ideal body shape?In the first place, can you overcome a sense of bitterness towards women!?

俺はインストラクターを目指す専門学生。
夏休みに入ろうかというある日、フィットネスジムのバイトのお誘いがあった。
連絡主は、ジムを経営している従姉の摩央姉ちゃん。 やり取りは数年ぶりだ。渡りに船と、姉ちゃんのマンションに住み込みでバイトを始めることになった俺。
しかし流されるままに、いきなり何人もの女性の専属担当にされてしまう !?
どうやら昔のトラウマで女性が苦手になってしまった俺を心配して、姉ちゃんが一計を案じてくれたらしいのだが……集まったのは、反抗的だったり非常に意思の弱い女性だったり。
俺は、理想の体型になりたいという彼女たちの期待に応えることができるのか？そもそも、女性への苦手意識が克服できるのか !?
