A female instructor at the Pussy and Anus Licking Training Center takes a slave to a private room. The female instructor sits on a chair, puts a collar, leash, and eye mask on the slave, and says, "If you do as I say, I'll take off your chastity belt and let you jerk off," then takes off her own panties and starts masturbating. The female instructor tells the slave to move his tongue up and down, and pulls the leash so that the slave's tongue touches her pussy. The slave continues to move his tongue like a machine and licks her pussy. The female instructor uses the slave as a cunnilingus machine and enjoys pleasure. After the female instructor makes the slave lick her pussy until orgasm, she says to the slave, "You weren't good at licking, so I'll postpone the jerk off. Sorry I'm the only one who gets to have a good time, hahaha." The female instructor never intended to make the slave jerk off from the beginning, she just wanted to use the slave as a cunnilingus machine.
