The female private tutor visits her male student with her big tits exposed, deliberately flashing him to arouse excitement. Filled with sexual frustration, she seductively tempts the boy, making his cock hard. Noticing his arousal, the tutor proposes a condition: if he abstains from ejaculation for ten days, she'll go on a date with him. The student agrees, enduring days of enforced abstinence, accumulating thick semen. During this time, his cock is brought repeatedly to the brink of explosion, tormented endlessly by the tutor in a hellish ten-day ordeal. As the boy reaches his limit, begging for mercy, he also finds these ten days to be an almost dreamlike experience.
