However, his mother's body is hot from being hugged by her son earlier, so she masturbates in the bath. The son is aroused by the sight of his mother after the bath and forcibly kisses her! The son's hands continue to squeeze her voluptuous big breasts... That evening, the son visits his mother again, unable to suppress his young carnal desires, and forcibly takes his mother's body.
