Nearly a year has passed since I married Satoshi and moved in with his family. After his wife died five years ago, my father-in-law devoted himself to his drone hobby. His playful personality is nothing like my overly meticulous husband's, and the contrast extends to the bedroom: my husband is cold and perfunctory, while his father is passionate and intense. Their affair begins when the frustrated wife is caught masturbating after another unsatisfying night with her husband. From then on, her father-in-law fucks and creampies her after every baby-making session with her spouse.
