Making her AV debut as a virgin with no prior sexual experience, Itsuka Saya takes on the challenge of reaching her first orgasm. Enduring the male performers' relentless teasing, her panties are pulled off to reveal she's already wet and aroused. Gradually surrendering to the vibrations of the vibrator, her body twitches and trembles—then suddenly, Saya jerks violently. In that instant, her heart opens, and she steps into the world of sex. Through threesomes, intercourse, and various other acts, her pleasure builds until she's shaking so intensely she can barely stand—capturing her very first climax. Witness the pure, honest experience of her first time.
