[Synopsis]

Fed up with the tyrannical attitude of idol Aya, the manager seeks the help of legendary trainer ''Marao'', who is said to be able to rehabilitate any idol.
Faced with the overwhelming difference in physique, Aya's nipples and private parts are forcibly touched but she continues to resist without changing her cocky attitude.
However, as soon as she sees Marao's penis, her attitude changes completely and she desperately begs him not to let it go inside her...but a thorough punishment, called special training, begins.
