When my father-in-law opened the door to take a bath, my wife was taking a shower. The father-in-law who happened to see her daughter-in-law's body leaks, "How beautiful. I envy my son...". The daughter-in-law, who was happy with the words, washed her father-in-law and fellatio. The two of them get closer because of this event. At night, after her husband is fast asleep, the daughter-in-law visits her father-in-law's room in hopes of being held, and they cross the forbidden line.
