When her son says, "A friend is coming over," the mother falls into uncontrollable lewd fantasies. Using the friend's visit as an excuse, she sends her son away and indulges in satisfying her own desires. In those stolen moments, she fantasizes about her son's groin and continues to masturbate obsessively. Calling out her son's name repeatedly, she can no longer suppress her feelings. Though initially confused, the son gradually comes to understand his mother's loneliness and isolation, eventually resolving to become one with her.
