MIDA-492 | A 21-year-old college student, 146 cm tall, with only one friend, and the only member of Japan's "Erotic Research Club," is named Hiyori Sasakura. This is a 150-day documentary following an ordinary girl who is "just into erotica" until her AV debut.

On a certain day in a certain month, a direct message arrived addressed to the director.

"I'm in an erotic research club with my friends at university, and I wanted to try various things before graduating, so I became interested in appearing in an adult video."
"If you're interested, I'd like you to reply."

This message came from a 21-year-old, currently enrolled female university student.
Intrigued by her activities in this mysterious club, we staff members decided to meet her.

Her name is Sasakura Hiyori. She claims to be 146 centimeters tall. But she probably looks even smaller.
In her research lab, where she works in Japan's only "erotic research club," dildos are placed everywhere.

"I like this size when I masturbate."

She wears plain glasses, and her voice and height are both small.
Yet, she's innocent and like a small animal. Cute.

We wanted to get to know this girl better. We decided to film at her home as well.

Her first time undressing.
Shy in front of the camera, yet her body is revealed.
Her underdeveloped breasts,
and her fully grown adult pussy, are both erotic.

Just observing her pussy makes it wet.
Maybe this girl is kinky.

Her first time having sex.
Where did the quietness of a small animal from before go? The moment I touched her, sounds poured out of Hiyori's mouth one after another.
"I didn't know she could make sounds like that..." I thought, as she couldn't stop breathing or speaking.

When I applied her favorite vibrator, her senses suddenly soared, and her body reacted honestly.
She came again and again, unable to control herself, soaking the sheets.
She's shy, yet she can't resist the pleasure.
That contrast is just so raw and erotic.

I never imagined that a quiet, plain girl with glasses would make so much noise and become so disheveled.
Honestly, it was beyond my imagination.

This girl isn't just an ordinary curious college student.
She might be an extraordinary talent.
