One day, the director received a DM.
"I'm in a circle called Erotic Research Club with a friend at university, and before I graduate, I want to try various things, so I'm interested in appearing in AV."
"If possible, please reply."

A message from a 21-year-old active female college student.
The staff became interested in this girl active in a mysterious club and decided to meet her.

Her name is Sasakura Hiyori. She claims to be 146cm tall, but she looks even smaller.
Her research room in Japan's only "Erotic Research Circle" has dildos placed everywhere.
"I like this size for masturbation."
Wearing plain glasses, with a small voice and small stature, yet innocently like a small animal. Cute.
We wanted to know more about her and decided to film at her home as well.

First undressing.
Although embarrassed in front of the camera, her body gradually reveals itself.
Her underdeveloped-looking breasts and her adult-grown pussy are both erotic.
Her pussy gets wet just from being carefully observed.
Maybe this girl is actually very lewd.

First sex.
The quietness like a small animal from earlier is gone — the moment she is touched, sounds keep overflowing from Hiyori's mouth.
She makes so much noise that you think "She can make sounds like this...", unable to stop breathing or speaking.
When her favorite vibrator is pressed against her, the sensation skyrockets and her body reacts honestly.
She has uncontrollable orgasms that soak the sheets over and over.
Although shy, she cannot resist pleasure.
That gap is incredibly raw and erotic.
A quiet plain glasses girl making such loud noises and getting so wildly disordered —
Honestly, it was far beyond imagination.

This girl is not just a curious college student.
She might be an incredible talent.
