My father-in-law awkwardly asks when we plan to have children because he cannot wait to see a grandchild. He invites the family on what sounds like a fishing trip, but it is really a fertility getaway at a seaside hot-spring inn, complete with a month of abstinence beforehand. On the day of the trip, however, my wife cares more about fishing than trying for a baby. Frustrated that night, I accidentally glimpse my mother-in-law’s seductive body in the bath, lose control, and repeatedly cum inside her until she becomes pregnant—something I can never confess to my wife.
