Her husband is away on a business trip, leaving his father-in-law at home. Naturally, she's not getting satisfied and spends her days filling the void with masturbation. One day, her father-in-law catches her in this state. Feeling sorry for his daughter-in-law, he decides to take matters into his own hands, forcefully taking her virginity. While she initially resists, her guilt over her husband gradually fades, and she starts seeking out her father-in-law for the pleasure he provides, a pleasure she can't find with her husband.
