While her husband is away on a business trip, Reiko finds herself overwhelmed with loneliness. One day, her son says tenderly, "I could tell you were lonely, so I came home early to be with you." Behind those warm words, however, lies his deep desire. He reaches for her breasts, entwines his tongue with hers, and soon slips his hand beneath her pantyhose. Overcome by pleasure she hasn't felt in years, Reiko forgets her role as a mother and surrenders her body and soul completely to her son. A poignant, bittersweet moment of warmth and forbidden passion.
