The female tutor gives a handjob to the dick of a student who hasn't ejaculated in three months while still in a chastity belt, and says, "Do you want to let out all your saved up sperm? Hehe, even when it's erect it's an uncut dick, hahaha." Then, when the student is about to ejaculate, the tutor takes her hand off the dick and says, "If you ejaculate, you'll spill everything you've learned, so that's bad. You were so close to ejaculating, hahaha." The tutor makes the student smell and lick her sweaty feet and armpits, and laughs. While the student is memorizing while performing cunnilingus, the tutor reads a book and hits the student with a riding crop for being bad at cunnilingus. The tutor is the only her cum by cunnilingus, and feels a sense of superiority when she sees the student who is unable to ejaculate because of the chastity belt.
