Mother and son always had a close relationship, so intimate that the son would openly seek physical affection from his mother without caring about his father's presence. One day, the father went on a business trip, and the son looked forward to finally having his mother all to himself. But instead, the mother, feeling lonely in her son's absence, began masturbating to ease her longing. When the son discovered his mother in the act, he could do nothing but sulk. In that moment, the mother gently drew close to her son, tenderly embracing him and soothing his troubled heart.
