After 20 years of marriage, her 19-year-old daughter will be living alone from this spring. Now that she has finished raising her child, the desire to have sex has begun to grow in this married woman, turning her innocent wife into a lascivious one. Her shyness is fleeting, and before she knows it, she is mindlessly devouring a stiff, erect cock. Rather than feeling guilty towards her family, she wants to be honest with her own feelings... and simply surrenders to the pleasure of sex.
