A tutor with big, voluptuous breasts comes to the house of a male student who is not good at talking to women. She purposely shows off her breasts as if to seduce the male student, who is sexually frustrated and has a constant erection! The tutor notices this and promises to go on a date with him if he can refrain from ejaculating for 10 days. The tutor makes the male student abstain from sex for several days and accumulates thick semen! She plays with the male student's dick, which is on the verge of exploding... It's too much... Please forgive me! A hellish yet dreamlike 10 days in which the tutor keeps playing with the male student's dick.
