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. <br><br>"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."<br>"If you're interested, I'd like you to reply."<br><br>This message came from a 21-year-old, currently enrolled female university student.<br>Intrigued by her activities in this mysterious club, we staff members decided to meet her.<br><br>Her name is Sasakura Hiyori. She claims to be 146 centimeters tall. But she probably looks even smaller.<br>In her research lab, where she works in Japan's only "erotic research club," dildos are placed everywhere.<br><br>"I like this size when I masturbate."<br><br>She wears plain glasses, and her voice and height are both small.<br>Yet, she's innocent and like a small animal. Cute.<br><br>We wanted to get to know this girl better. We decided to film at her home as well.<br><br>Her first time undressing. <br>Shy in front of the camera, yet her body is revealed. <br>Her underdeveloped breasts, <br>and her fully grown adult pussy, are both erotic. <br><br>Just observing her pussy makes it wet. <br>Maybe this girl is kinky. <br><br>Her first time having sex. <br>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. <br>"I didn't know she could make sounds like that..." I thought, as she couldn't stop breathing or speaking. <br><br>When I applied her favorite vibrator, her senses suddenly soared, and her body reacted honestly. <br>She came again and again, unable to control herself, soaking the sheets. <br>She's shy, yet she can't resist the pleasure. <br>That contrast is just so raw and erotic. <br><br>I never imagined that a quiet, plain girl with glasses would make so much noise and become so disheveled. <br>Honestly, it was beyond my imagination. <br><br>This girl isn't just an ordinary curious college student. <br>She might be an extraordinary talent. <br><br>A 150-day documentary following 'just a naughty girl' as she becomes AV actress Hiyori Sasakura.
