Hell's Revenge(愛欲の標的)

Kenzo, Azusa's husband, has a heart condition but his passion for sex has not diminished one iota from the time he was still a virile, young man. Azusa does not refuse her husband for he is a money bag and if he should die of excess sex, she will come into a vast fortune. If only Azusa could kill him without staining her own hands... Unable to do it alone, she asks the aid of Naoya who is only too glad to help.
