Mother wants to cum with her son!

My father left the house after finding a woman outside. My mother, who was left at home, was depressed and felt lonely. The son, worried about his mother, tries to cheer up his mother on his place of his father when he leaves. The mother suddenly bursts with loneliness that she had been holding back by touching her son's kindness, and she finds herself craving her son's body. I want to be with you forever, with the feeling that "I don't want to be alone anymore!" I don't want to leave! I want to cum together! I began to strongly think this way.
