Sayaka is a quiet, bespectacled literature girl who frequents the library. She appears to be a total bookworm with no interest in men, but in reality, she has an intense sex drive and can't stop her dirty fantasies. Two virgin guys approach her alone in a secluded room, leading to a thrilling encounter. In her first time with a real cock, the inexperienced guy finally unleashes his pent-up lust through masturbation, only to be deflowered in a creampie-filled, female-dominated sex session.
