On a certain day in a certain month, a direct message arrived addressed to the director.<br /> "I was in an erotic research club with friends at university, and I wanted to try various things before graduating, so I became interested in appearing in adult videos." "I would appreciate it if you could reply if you don't mind."<br /> This message came from a 21-year-old female university student. Intrigued by her activities in a mysterious club, we staff members decided to meet her.<br /> Her name is Hiyori Sasakura. She claims to be 146 centimeters tall, but she probably looks even smaller. Her research lab, where she works for Japan's only "erotic research club," is filled with dildos everywhere.<br /> "I like this size when I'm masturbating."<br /> He wears plain glasses, speaks softly, and is short. Even so, her innocent nature makes her seem like a small animal. So cute.<br /> I want to get to know this c** better. I'll be taking photos at home as well.<br /> First time undressing. Shy in front of the camera, yet her body is revealed. Even breasts that seem underdeveloped, Even a fully grown adult pussy is sexy.<br /> Just by observing it closely, her pussy gets wet. This girl might be a pervert.<br /> My first time having sex. The stillness that had been there just moments ago, like that of a small animal, was nowhere to be seen—the moment she was touched, voice after voice began to pour from Hiyori's mouth. "I can't believe I can make sounds like that..." I thought, unable to stop breathing or speaking.<br /> When I apply my favorite vibrator, my senses suddenly surge, and my body reacts honestly. Uncontrollable orgasms come over and over again, soaking the sheets. She's shy, but she can't resist the pleasure. That gap is incredibly raw and erotic.<br /> I never imagined that this quiet, unassuming girl with glasses would raise her voice and become this disheveled. To be honest, it exceeded my expectations.<br /> This girl isn't just any curious college student. He might be an extraordinary talent.<br /> A 150-day documentary closely following the transformation of 'just a naughty girl' into AV actress Hiyori Sasakura.
