Seven years into marriage, she and her husband move back to his family home after her father-in-law suggests living together. Sharing expenses eases the financial burden of fertility treatments, but it does nothing for her other problem: an unsatisfying sex life. Her premature husband falls asleep as soon as he cums, leaving her frustration to build. One day, unable to bear it any longer, she masturbates while both men are away—only for her father-in-law to return for his forgotten wallet and catch her. He begins satisfying what his son cannot, repeatedly creampieing her after she has sex with her husband in their attempts to conceive.
