Yuriko, who caught her son masturbating. Yuriko can't get the image of her grown son's erect dick out of her head and starts masturbating in her bedroom. Her son senses something unusual with the sounds coming from the bedroom and peeks inside. The son also catches his mother masturbating. 'I can't hold back anymore,' says the son, to which the mother responds, 'Just this once.' But the son isn't satisfied with just once; he begs his mother, 'It's okay here, right?' asking for anal sex, and the mother accepts him.
