Nami's husband is so busy with work that he rarely comes home, leaving her unable to have sex and desperate for release. One day she catches her live-in father-in-law napping with an erection. Addicted to sucking cock, Nami cannot resist a dick even bigger than her husband's and crosses the line by putting it in her mouth. As the pleasure consumes her, she eventually begs to become her father-in-law's personal sexual outlet.
