An overprotective mother dotes on her teenage son excessively. One day, in an attempt to encourage her son who is working hard in his studies and club activities, they take a bath together for the first time in a long time. Seeing his mother's large breasts, the son becomes wildly excited and gets an erection! His mother, aroused by her son's adult penis, engages in incestuous sex out of love. Throwing away her shyness, she shakes her large breasts and begs her son to cum inside her many times.
