"I've only shot a few AVs so far..." Sae, an aspiring AV actress, is a little nervous because she doesn't have much experience in filming. This time, she'll be experiencing a special first time. "A masturbator?" "Deep throat?" She's shaken by the things she's never heard before, but her dormant erotic instincts are awakened, and she arouses the desires of men and tempts many dicks one after another. This is a documentary about Sae Saeko Mashiro's AV training, following her first time.
