SQIS-106 My son’s young wife, the scent of a female spreading throughout the house is irresistible

The old father, whose heart is free, indulges in obscene fantasies about his wife. His lust knows no bounds, and he ends up reaching for her underwear. Unfortunately, his wife catches him in the act, leaving him dejected. He feels embarrassed, but perhaps inspired by his father’s lust, the wife herself feels strangely excited. Then, one day, the once-healthy son falls ill and is forced to recuperate. Father-in-law and daughter-in-law… this rare opportunity leads to the two of them becoming one. (From Episode 1)
