A lewd stepfather who has retired and is now free to join his wife

Ami has been married to Haruo for three years. I've been without sex for the past few months with Haruo, who has been hoping for a baby but is busy with work. Perhaps knowing this, her stepfather who lives with her begins to lewdly approach Ami. When I was unable to talk to anyone, my father-in-law's actions continued to escalate... Finally, Ami accepts it!
