The person who came this time was ``Yuna-san, 25 years old,'' who works as a dental assistant.
My first impression was that she was a beautiful older sister.
When the interview started, I fidgeted with my hands and fidgeted throughout.
Huh? I wonder if she's not used to being a man?
I had the impression that dental assistants love going on blind dates and drinking and having fun, but that doesn't seem to be the case with Yuna-chan.
When a girl who seems to be reliable turns out to be unexpectedly inexperienced and shy, there is a gap between her and her partner.
Because it's a workplace where there are many women, it's hard to meet anyone.
Sometimes when a customer of my type comes over, she can't give him her number, so she purposely touches her breasts during treatment. I have a dream.
Perhaps it's because of his profession, but the type of man he likes is a man with beautiful teeth.
It seems like I have a balance of teeth and gums that I like, so whenever a customer of any type comes over, I fantasize about having a deep kiss with that person and sometimes end up masturbating at night.
Not having any encounters is of course frustrating.
Please take a look at the gap before and after Frustrated Sister begins.
