Two years have passed since the death of her husband, yet sorrow continues to stir deep within her heart. All that remains is a meager inheritance and her stepson. But now, she can no longer suppress herself. Shameful desires gnaw at her mind, growing stronger each day. One day, the mother accidentally enters her son's room and discovers SM magazines and soiled panties hidden beneath his bed. In that instant, her long-repressed desires are finally unleashed—her masochistic cravings, now awakened, begin to draw her toward her son. Without realizing it, she starts devising schemes to seduce him. Yet this is no mere erotic romance. It is a new beginning, one that will deepen the bond between them in ways unimaginable.
