In order to prevent a bad student from repeating the year, a female teacher goes wild until the morning under the pretense of supplementary lessons! "I'll make you a capable man," she says, tempting the goddess and training the devil, giving him 13 all-night cumshots! No matter how many times he cums, the more he ejaculates, the better his grades will be. A dream lesson where he gets milked until his balls are empty and he climaxes endlessly! Even a delinquent in the midst of puberty runs away from the abnormal sexual desire of the lewd teacher who won't stop even if he cums inside until the sperm flows back.
