A woman lives happily with her husband until his estranged father suddenly arrives. After five failed marriages, the father-in-law is allowed to stay only until he finds work, but within days he takes control of the household and sees through her sexual frustration. He deliberately displays his swelling crotch while pretending to sleep, and she finally gives in to instinct and masturbates beside him. As if he had been waiting for that moment, he rises from the bedding—and her promise to allow only a tiny bit of penetration leads to unexpectedly perfect sex and repeated orgasms.
