Between mother and son, a deeply intimate relationship flourished in secret, unknown to anyone else. While she maintained a strict demeanor toward her son in front of her husband, hiding her true feelings, behind closed doors she harbored intense longing for him. In their daily lives, the mother poured affection onto her son, gradually enveloping his heart completely. Her feelings grew stronger each day, until she came to love him so intensely that she could no longer tolerate him masturbating without her.
